An industrial baghouse dust collector, when paired with an industrial blower, pulls in air and cleans dust, dirt and other particulate matter generated by manufacturing processes from it.

As part of an , baghouses help provide workers with a safer environment by improving air quality, reducing fire and explosion hazards, removing hazardous particulates and improving productivity through ease-of-maintenance. Baghouse dust collectors also prevent particulate matter from entering the atmosphere. How does a baghouse system work? That’s where engineering and design play a key role.

How a Baghouse Works: Baghouse Dust Collector Working Principles

While they鈥檙e built in different designs and sizes, all baghouses essentially operate in the same way. Air from an industrial environment enters a baghouse through an air inlet or duct. The baghouse contains rows of fabric tube-shaped bags, which filter the particulate matter and other contaminants from the air. As the air passes through the fabric, dust and other particles are separated from the air. Smaller particulates collect on the bags and larger particulates fall into a hopper below.

After the air is filtered, it moves out of the baghouse through a clean air outlet or duct. A cleaning mechanism or system (a few examples of these mechanisms are outlined below) also works to remove built-up particulate from the fabric bags, causing it to fall into the hopper below.

Baghouse Dust Collector Types

While baghouse dust collector systems all work in the same basic way, there are a few different varieties.

• Reverse air dust collectors, for example, use a low-pressure reversed flow to backflush the air through the filter bags.
• Pulse jet dust collectors, meanwhile, use puffs of pressurized air, pulsing air through the filters.
• Shaker dust collectors are used in facilities where compressed air is impractical, like mines. These dust collectors use mechanics to shake dust from the filter bags and are common for certain particulates more easily separated from filters, like chicken dander and feathers.

淫乱社区 and Baghouse Dust Collectors

淫乱社区 has designed, , and hundreds of baghouse dust collection systems across a variety of industries, including mining, pulp and paper, foundries and beyond. Each system is designed to specifically address particle types, explosion protection guidelines, regulatory emission rates and much more. Whether built for fumes, fine or heavy dust, each custom-engineered baghouse provides cleaner and safer facilities and workplaces.

How Do Baghouses Work For You?

Now with an understanding of how a baghouse works, you can decide whether an industrial baghouse dust collector is the solution for you.

A fully functional baghouse dust collector is important for the safety of your employees and your business. When problems arise鈥攅ven small ones鈥攊t puts your operation at risk of shutdowns, exposes you to regulatory citations and can impact your bottom line. Fortunately, some common problems are simple to diagnose and have affordable solutions. Here鈥檚 a guide to baghouse troubleshooting.

Common Baghouse Problems

High Differential Pressure and/or Short Bag Life

Experiencing high differential pressure or unexpectedly short bag life are common issues in baghouse systems.

Probable Cause: Maintenance Problems

The most common source of problems with baghouses arise from poor bag installation, a faulty differential pressure gauge, leakage through the discharge device, valve and solenoid failures, wet or oily compressed air, a faulty timer or wet bags.

Probable Cause: Design Problems

Design-related issues are a potential culprit when encountering high differential pressure or reduced bag life. Possibilities include high dust loading, high air-to-cloth ratio, high can velocity, improper fabric or surface treatment or an improper or undersized discharge device.

Probable Cause: Operational Problems

During the baghouse troubleshooting process, consider whether operational issues such as improper start-up sequence, improper damper settings or high moisture content and lower temperature in the gas stream may be the cause.

Low Differential Pressure

Low differential pressure in a baghouse signals underlying issues that might affect performance.

Probable Cause: Operational Problems

Operational issues can often result in low differential pressure, primarily due to over-cleaning of bags due to excessive pulse pressure or pulse frequency.

Probable Cause: Maintenance Problems

Regular maintenance is key to ensuring consistent differential pressure. Look for plugged lines or broken or uncoupled manometer lines.

Dust Emission to Atmosphere

Baghouse dusting can reduce efficiency and risk non-compliance.

Probable Cause: Design Problems

Design flaws can lead to baghouse dusting issues. In baghouse troubleshooting, look for an extremely high air-to-cloth ratio, poor seal arrangement, extremely fine dust (or very fine spherical particles), the wrong fabric or surface treatment or the wrong bag size.

Operational Problems

Operational settings and procedures can also contribute to baghouse dusting. Consider whether a wrong damper setting or poor start-up procedure are the culprit.

Maintenance Problems

On the maintenance side, several issues can lead to baghouse dusting. They include poor bag installation or seal, tubesheet leaks, holes in bags or bad diaphragms or solenoids.

Puffing Back

Puffing back is when dust re-enters the dirty air stream.

Probable Cause: Operational Problems

If operational causes lead to puffing back, it鈥檚 likely from a high pressure drop across the baghouse, low system fan speed or improper duct balancing.

Maintenance Problems

Plugged duct lines and poor hood designs are two maintenance causes to consider.

Excessive Hopper Build-up

Probable Cause: Design Problems

Among the reasons design could play a role in excessive build-up in the hopper: a too-slow or faulty rotary air lock, the outlet is too small, there鈥檚 an improper discharge device or improper hopper slope.

Probable Cause: Operational Problems

The failure to initiate the discharge device prior to start-up or operate the discharge device after the fan has shut down may cause excessive build-up in the hopper.

Probable Cause: Maintenance Problems

Maintenance issues could lead to excessive hopper build-up when the rotary air lock needs rebuilding, there鈥檚 excessive rust or build-up on the hopper walls or material has become packed and won鈥檛 flow.

Low Dust Discharge

A few operational or maintenance issues can lead to the insufficient removal of collected dust from the baghouse hopper or discharge system.

Probable Cause: Operational Problems

Leakage at discharge points and re-entrainment of dust on filter bags can be operational causes of low dust discharge.

Probable Cause: Maintenance Problems

A malfunction of the discharge valve, screw conveyer or material transfer equipment might be an issue. Or re-entrainment of dust within the collector could be due to possible leaks in the hopper.

Holes in Bags

There are many potential causes when holes are found in bags.

Probable Cause: Design Problems

Improper fabric, an inlet abrasion from excessive inlet velocity or turbulence or bags rubbing together a warped tubesheet could create holes.

Probable Cause: Operational Problems

Too-high inlet temperature, sparks in the inlet gas stream, or high moisture mixed with moderate heat causing hydrolysis are possible culprits.

Probable Cause: Maintenance Problems

A few maintenance issues need investigating, including the failure to clean the tubesheet (leading to abrasion from the inside), bent cages rubbing against the walls or each other, excessive pulse cleaning, bags damaged during installation, broken cage wires, or improper bag installation.

Loud or Unusual Noises

Noises can cause headaches in more ways than one. Either maintenance issues or, in the case of a pulse jet baghouse, the pulse system may be to blame.

Probable Cause: Maintenance Problems

Vibrations, banging of moving parts or squealing of belt drives can cause excessive noise. Addressing these maintenance issues will generally address the noise issue.

Probable Cause: Pulse System

Unexpected noises can be caused by valves not properly pulsing or a compressed air leak in a pulse jet baghouse.

Baghouse Corrosion

When you see signs of corrosion, here鈥檚 where to begin your baghouse troubleshooting.

Probable Cause: Operational Problems

Dew point excursions and improper shutdowns and startups can lead to corrosion.

Probable Cause: Maintenance Problems

Improper paint, material, or application, improper insulation and emission of nearby equipment are also common corrosion causes.

Baghouse Troubleshooting: When to Seek Outside Support

Sometimes in-house baghouse troubleshooting can only get you so far. Whether you need help identifying the root problem or know what the problem is but need help to address it, 淫乱社区 can help. When problems persist or maintenance is needed, contact 淫乱社区鈥檚 expert team to schedule baghouse troubleshooting help, repair or service.

Who needs to do a baghouse leak detection test?

Anyone who owns or operates a dry-type dust collector, such as a baghouse or cartridge collector, needs to do a baghouse leak detection test.

How often do you need to do a leak detection test?

Leak detection tests should be done every time you do a filter change. Some regulatory requirements dictate that leak detections need to be done on an annual basis, or a six-month basis, and then also any time you suspect a leak in your system, a leak test is good to help diagnose where that leak is coming from.

What are the risks of not doing a leak detection test?

Filter changes are a fairly expensive operation, so not doing a leak detection test could mean all the money you spent on that filter change is thrown out because of an improper installation.

Additional reasons to conduct these tests, and reasons to mitigate the risk by doing them, is because a hole in your filter could mean a failure to comply with regulatory requirements.

Step by step: The baghouse leak detection system

Before conducting the test, you鈥檙e going to want to consult your safety department to ensure that all lockout, tagout and confined space procedures are followed for this procedure.

Step one is we are going to be inserting the dye into the system. In this case, we鈥檙e going to insert the dye (or baghouse leak detection powder) into the hopper here. [In your system, dye may need to be inserted into the collection ductwork.]

Now that our dyes have been added, we鈥檝e ensured that our filters are evenly coated, we are going to do an inspection of the clean-air side of our bags to ensure that none of the dye made it through or around the filters and ensure we have a nice, good installation.

Now we鈥檙e up on the clean-air section of the baghouse. Because this thing is so small, we can actually lift off the entire roof of it. So first I鈥檓 going to do a quick initial inspection to see if I see any dye. Usually, if there鈥檚 a major leak, you鈥檒l see it instantaneously. But now that we don鈥檛 see any, we鈥檙e going to actually do the blacklight portion and turn off the lights and see what we can see.

All right. Since in our test we didn鈥檛 see any leaks, we wanted to show you we scattered some dye around here and wanted to show you what it would look like if there was a leak and how vividly that shows up.

Whether you purchased your baghouse from 淫乱社区 or not, 淫乱社区 can assist in these leak detection tests and help diagnose problems and come up with long-term solutions.

Common Dust Collector Maintenance Issues

When we approach a plant, a lot of the most common maintenance issues we see, and the easiest to find, are going to be the worn out duct work or low velocities, low volumes in the system. Holes in the ductwork can compromise the performance of the dust collection system.

What you’re going to look for is where those holes are, what the sources are, what the total volume on the system is, see if there’s blanking in any of the filters. Then, take it back to the collector and check to make sure that all the filters are working, not leaking through the tube sheet, and then take it back even as far as the fan or the exhaust. We want to keep everything running as designed and that the volumes are where they need to, otherwise it can just further compromise the ductwork.

Routine Maintenance Matters

The dust collection systems, a lot of times, are a project that’s put in, they get a lot of attention when they get put in, and then there may be turnover of staff, there may be a long period with no maintenance, so it’s not high on the radar. It’s just something that sometimes just goes by the wayside.

A Team With Vast Dust Collector Maintenance Knowledge

What sets 淫乱社区 apart in our maintenance services is basically our knowledge of the systems. We do build our own dust collectors, we build a lot of our ductwork, we handle everything from the design, through the fabrication, through the installation, and then as well the maintenance.

Having a diverse staff, we have the ability to react quickly. Having our own fabrication shops in three different states also allows us to get anywhere in the U.S. within a fairly short turnaround.

Dust Collector Hood Types

Along with size and airflow rate, good hood design relies on the type of hood and where it鈥檚 located in relation to the manufacturing process. There are two primary types of dust collection hoods: enclosing hoods and capturing hoods.

Enclosing hood

An enclosing hood keeps the contaminant within the hood. These hoods completely or partially enclose a process so particulates cannot escape.

Capturing hood

A capturing hood is located next to the contaminant source. These hoods must be designed to draw and capture contaminant from outside the hood.

At 淫乱社区, we begin each design with the intent to use enclosing hoods, if possible, as they are better at helping to eliminate fine particulates, toxic contaminants and more. They also take less energy to do the job effectively.

淫乱社区鈥檚 Approach to Industrial Dust Collector Hood Design

Because hoods are so crucial to a dust collection system鈥檚 functionality, we treat each of our dust collection hood design projects as unique. In other words, we never copy hoods from project to project. Instead, we consider the combination of the contaminant鈥攊ts density, size and toxicity鈥攁long with the manufacturing process. That鈥檚 where ingenuity and engineering come into play. The ingenuity is making sure the dust collection hoods fit within customers鈥� applications and needs. The engineering is using proven industry equations to determine volumetric flow rate.

We start many projects with computational fluid dynamics (CFD) modeling to visualize air flow patterns and determine capture velocities within the hoods and to measure pressure drops.

In addition to CFD modeling, we also use our R&D test lab to simulate real-world applications. In the lab, we test either full-size or small-scale models to ensure they capture contaminants effectively before we fabricate and install full-size hoods.

Issues with Improper Dust Collector Hood Design

We鈥檝e seen first-hand the effects of improper hood design. The most common hood design error we see in the industry is placing the hood too far away from the where the contaminant is generated. A hood鈥檚 primary purpose is removal of dust and other particulates from the process. When a hood doesn鈥檛 do that properly, issues multiply.

We鈥檝e seen a specific instance of this in a tissue converting application where dust was settling on top of the hood rather than being pushed into the hood. This accumulating dust is hazardous for two reasons: It is a risk for fire and employees鈥� health and safety. In an industry where stringent production schedules rely on little downtime, maintenance crews had to stop production to clean the accumulated dust. It was a clear case of a dust collection hood not meeting design goals.

One Source for Dust Collector Hood Fabrication, Design

At 淫乱社区, we believe metal fabrication is as important as hood design. When building our hoods, we use abrasion-resistant or heavy-gauge materials to ensure they stand up to applications where particulates may cause wear and tear. In addition to ensuring we have smooth welds that won鈥檛 trap dust, we also use our fiber optic laser to accurately and precisely cut slots out of our hoods. Our laser cutter not only leaves the finished product looking aesthetically better, it also ensures a more accurate slot for better performance.

If you have noticed dust buildup in your facility, an improperly designed hood may be the cause. Contact us to see how our dust collection hood design experts can help make your facility and manufacturing process cleaner and safer.

When to replace baghouse filters

For the most part, there are only three reasons to change baghouse filters:

• When they can no longer be cleaned because dust has accumulated to the point of plugging the fabric鈥檚 air passages, keeping the vacuum from pulling in unwanted dust.
• When the bags have developed holes.
• When the regulates your company or industry to change bags.

While some facilities change bags once per year because their dust collectors capture large quantities of especially fine, hazardous dust, most of 淫乱社区鈥檚 customers can go two to 10 years before having to schedule dust collector bag replacement.

Facilities that change bags more than once a year may be doing so because of a unique situation鈥攖he collector is capturing an especially tough material, like a wet, corrosive or abrasive dust. Facilities that change bags often but are not in this situation likely have a dust collector that doesn鈥檛 correctly match their manufacturing process.

Checking your industrial dust collection system

If you鈥檝e just installed a new industrial dust collection system, it鈥檚 best practice to check the system regularly to ensure it鈥檚 running efficiently and the bags have been installed correctly.

Here鈥檚 how to tell whether dust collector issues may be related to the bags:

• High differential pressure: Bags that haven鈥檛 been installed correctly, or are retaining excess amounts of dust, will lead to high differential pressure within the baghouse. As it becomes more difficult to pull air through the bags, the difference in the pressure before air enters the bags and after exiting the bags increases.
• Baghouse dusting: Dusting is noted by a visible emissions plume coming out of the stack or by dust in the clean air section of the collector. Bags that are the wrong size or fabric for the particulate may not be installed correctly, may not be sealed or have holes that are contributing to the dusting.

Replacing baghouse filters

Dust collector bag replacement: A quick tutorial

Before removing filters:

• Obtain and follow a Confined Space permit, if required.
• Manually pulse down existing filters.
• Allow the screw auger and rotary air lock to remove waste.
• Conduct proper lockout-tagout per or requirements.
• Ensure employees are trained on hazards associated with the task and are wearing the proper personal protective equipment.

Removing old filters (pertains to top-load bags only):

• Open clean air section doors and remove pulse tubes and cages. (Note: 淫乱社区鈥檚 baghouses do not use hold-down hardware, but if your baghouse does, remove this hardware before proceeding.)
• Flex the bag鈥檚 seal toward the center of the tube sheet hole and drop the bags into the dirty air section.
• Remove all the old bags that were dropped by accessing the hopper. Count the bags to verify you have removed them all to avoid damage to your dust collector.
• Dispose of dirty bags in a dust-tight bag or sealable waste container.
• Close and bolt or screw shut access doors.

Installing new filters:

• Vacuum the clean air section to remove accumulated dust and debris.
• Drop new filters鈥攐ne at a time鈥攖hrough the tube sheet.
• When the filter is unfolded into the dirty air section, flex the snap band toward the center of the tube sheet hole. Do not bend the snap band at the seam.
• Place the filter snap bands on either side of the tube sheet, and push the band toward the perimeter of the tube sheet hole. You鈥檒l hear the snap when it鈥檚 properly sealed.
• Slowly drop the cage down the center of the filter until the venture sits snug on the filter. Gently step down on the venture to seat the cage. If you have hold-down hardware, reinstall it.
• When all bags have been replaced, reinstall all pulse tubes.
• Inspect all the bags for uniformity.

We also recommend testing your system using a fluorescent powder. Starting your industrial ventilation system using this powder will allow you to see whether it is making its way through to the clean side of the bag. If it is, the bag has not been installed properly.

When, and if, you need to replace bags, we also recommend taking the following steps to prevent maintenance and reduce production downtime:

• Keep a bag location replacement chart.
• If you have consistent bag failures, retain a typical bag for inspection.
• Retain bags with unusual or non-characteristic failures.
• Maintain an adequate supply of replacement bags.

By maintaining and changing your baghouse filters when needed, your dust collector will run more efficiently at a lower cost.

Contact 淫乱社区 for assistance

Unfortunately, many things can go wrong during a dust collector bag replacement procedure. Improperly seated bags can lead to poor dust collection, which can lead to failing government regulation tests and to excessive dust in your facility, which can adversely affect product quality.

If you are unsure about changing your own baghouse filters, contact us. We will not only change dust collector filters, we also can help analyze your system to help extend bag life, thereby reducing how often you鈥檒l need to do one of the dirtiest maintenance jobs in industrial ventilation.

Types of industrial baghouse dust collectors:

• Pulse jet baghouse dust collector
• Reverse air baghouse dust collector
• Shaker baghouse dust collector

After learning about your facility, regulatory requirements and particulate matter you need to filter, the 淫乱社区 team taps decades of experience to identify the industrial baghouse dust collector that鈥檚 right for you. Here are the types of baghouses we consider:

Pulse Jet Baghouse Dust Collector

In pulse jet baghouse dust collector operation, puffs of pressurized air 鈥減ulse鈥� incoming air through the filters for cleaning. Pulse jet dust collectors are the most common type of baghouse dust collector used in industry today.

Reverse Air Baghouse Dust Collector

Industrial reverse air baghouse dust collectors are typically used in wood dust applications with larger chips or when particulate matter has low densities and/or large aspect ratios. Reverse air baghouse operation involves a low-pressure reversed flow to backflush the air through the filter bags. Once backflushed, the filtered air is released back into the environment for recirculation.

Shaker Baghouse Dust Collector

Industrial shaker dust collectors are occasionally used for areas and facilities where it鈥檚 not practical to have compressed air. Mechanical shaker baghouses remove particles by mechanically shaking the filter bags. This causes the heaviest pieces to fall into a hopper while the smaller pieces are stuck against the inside or outside of the bags, depending on the design.

Shaker baghouse dust collectors are nearly obsolete and have limited applications due to required regulatory efficiencies and necessary maintenance.

Custom Design Baghouse Dust Collector Capabilities

Whether your facility requires a reverse air or pulse jet baghouse dust collector, 淫乱社区 has a custom design-build department which allows us to conduct both engineering and custom design in-house for any type of industrial baghouse dust collector. We can design a unique baghouse to fit your needs according to regulatory emission rates, particle type, explosion protection guidelines, the size and type of your facility and air-to-cloth ratios.

• Whether adding new equipment or improving efficiency is the reason behind the installation
• Evaluating duct network, fans, dust collector and baghouse efficiency
• What 淫乱社区 will evaluate and the different areas an industrial dust collector manufacturer can help in

Reasons to consider a new dust collector installation

Facility managers may consider a new dust collector installation for two primary reasons:

• New equipment: Adding equipment likely will add to the amount of particulate sources that need to be collected.
• Improve efficiency: Oftentimes, dust collection systems become inefficient, leaving behind particulates that should be collected. If maintenance issues are ruled out, a new dust collector installation can help improve the overall performance of the dust collection system.

Evaluating whether you need a new dust collector installation

When considering a new dust collector installation, the first step is conducting an evaluation of the current system. This evaluation will determine the system鈥檚 current capacity and what modifications need to be made to keep the system running efficiently.

The following areas are evaluated:

• Duct network: Ducts are examined to measure flow volumes, velocities, static pressures and physical wear and appearance. This network also is inspected for dropout.
• Fans: Fans are examined to determine flow rates, rpm and system static pressure. Based on the findings and needs of the collection system, fans may need to be resized or resheaved to change fan rpm. In addition, a motor change may be necessary to meet required fan speed or necessary static pressure.
• Dust collector: The size of the dust collector indicates whether it has the capacity to pick up contaminants from needed areas. This capacity may need to be increased if more particulate is required to be removed from the area.
• Baghouse efficiency: The evaluation determines whether the baghouse has adequate air-to-cloth ratio to capture particulate efficiently.

淫乱社区鈥檚 evaluation

淫乱社区, an industrial dust collector manufacturer, has the engineering resources to conduct a thorough evaluation of your industrial air ventilation system. If you are experiencing inefficiencies in your system, we鈥檒l determine whether you have a maintenance issue or whether you need a new dust collector installation.

If it鈥檚 a maintenance issue, we can set up a regular maintenance schedule at your facility to ensure your system is running at peak efficiency. Because we鈥檙e an industrial dust collector manufacturer, we can also provide a turnkey solution, from evaluation to design and build, if you鈥檙e adding equipment.

Types of pulse controllers

Pulse controllers come in two types鈥攁 simple timer and an on-demand timer.

• Simple timer: With this pulse controller, an operator sets a timer for how often the pulse valve will pulse. With this type of controller, the bags are cleaned at the set interval even if they do not need cleaning. Typically, trial and error is used to set the frequency. This pulse controller is a lower cost option because its design is simple, and it is easier to set up. This controller works best with predictable or consistent loading, and it鈥檚 ideal for baghouses that need to be cleaned continuously.
• On-demand timer: For this pulse controller, the timer reads the differential pressure across the baghouse and initiates a pulse sequence once the differential pressure reaches a high set point. It continues to pulse until the pressure across the baghouse reaches the low set point. Once at the low set point, pulsing stops until the differential pressure reaches the high set point, and the sequence continues. Because filters are cleaned when needed, the advantages of an on-demand pulse controller are extended bag life and savings in compressed air.

Set up parameters for pulse controllers

Several parameters can be set on pulse controllers.

The simple timer has just two:

• Time the valve is open: This time correlates to how much volume of compressed air is released through the valve. A quick pop of air, for example, is just .05 of a second.
• Time the valve is closed: This is the amount of time between pulses. It can typically be set to anywhere from one second to several hundred seconds.

Besides high and low pressure, as well as those listed above, the on-demand timer also has the following parameters:

• Alarm pressure: Alarms can be set to tell an operator there is an issue with a bag. A high pressure alarm indicates a plugged bag. As an example, a high pressure set point may be six, and an alarm may be set for nine or 10. Conversely, a low pressure alarm indicates a bag needs to be replaced because of a leak or a bag has fallen off.
• Pulse sequencing: Operators can set the order that the valves release air. 淫乱社区鈥檚 Ecollector鈩�, for example, can have six to 16 valves, which can be programmed in sequence.

As an added note, when installing a pulse controller, avoid locations with direct sunlight or in close proximity to heat or an electromagnetic field as these can damage the controller.

Troubleshooting your pulsing system

If you experience issues with the pulse controller, there are several things you can check, depending upon the problem:

• Valves are not pulsing: Check the power to the timer, the differential pressure switch, header pressure, or the solenoid and/or diaphragm valve.
• Hissing sound from valves: This may indicate a possible compressed air leak.
  • If the solenoid air outlet is leaking, check:
    • The electrical connection
    • The sub assembly for debris
  • If the diaphragm valve outlet port is leaking, check:
    • The air line to the solenoid
    • Header pressure
    • The inside valve body for pitting and debris
    • The membrane for wear
  • Bags are not cleaning adequately: Check the pulse pressure, on-time and off-time, and pressure set points. It may also indicate the need for a bag change.

We also recommend that you keep an adequate supply of dust collector filters and pulse valve kits on hand to avoid the cost that comes with having delays in production.
