Posted by Tom Hobson on Jul 31, 2024 2:15:00 PM

Once you’ve selected and sized your dust collector to meet the specific needs of your application, it’s crucial to address several additional factors to ensure that this vital piece of equipment operates both efficiently and reliably. Whether you’re installing a baghouse, cartridge filter, cyclone, or a combination of these dust collection systems, meticulous attention to detail during both the pre-installation and post-installation phases can significantly impact performance and longevity. Here’s an expanded guide covering essential aspects to ensure a seamless installation and optimal operation of your dust collection system:

Sizing and Placement

  1. Verify Dimensions and Fit:

    • Detailed Measurements: Before proceeding with installation, meticulously recheck the overall dimensions of the dust collector. This includes not only the dust collector unit itself but also the space required for ancillary components such as fans, discharge valves, collection containers, and ductwork.
    • Planning for Future Needs: Consider future expansion or modification needs. If you anticipate additional equipment or changes in the system, ensure that the space you allocate can accommodate these future upgrades without requiring significant reconfiguration.
  2. Allow for Maintenance Access:

    • Routine Maintenance Space: Adequate space around the dust collector is essential for routine maintenance tasks such as changing filters, inspecting components, and performing necessary adjustments. This space should also facilitate safe and efficient work, reducing downtime and improving overall system reliability.
    • Emergency Access: Plan for easy access in case of emergencies. Quick access points can make it easier to address unexpected issues or system failures, minimizing potential operational disruptions.
  3. Consider Environmental Factors:

    • Ventilation: Ensure that the installation location has adequate ventilation to prevent overheating and to maintain the effectiveness of the dust collection system. Poor ventilation can lead to decreased performance and increased wear on equipment.
    • Temperature and Humidity Control: Evaluate and manage environmental conditions, including temperature and humidity. Extreme temperatures or high humidity levels can affect the performance and lifespan of the dust collector, potentially causing operational problems or premature equipment failure.
  4. Space for System Components:

    • Clearances for Components: Account for the space needed for all system components, including bracing, supports, and controls. Adequate clearance helps prevent interference with system operations and facilitates easier installation and future maintenance tasks.
    • Accessibility for Ductwork: Ensure that there is sufficient space for installing and accessing ductwork. Proper ductwork design and installation are critical for maintaining efficient airflow and preventing dust buildup within the system.

Discharge Airlock Valve

  1. Select the Appropriate Valve:

    • Compatibility with Dust Type: Choose a valve that is suited to handle the specific type of dust being collected. For example, abrasive dust may require a valve with durable components, while sticky dust might need a valve designed to prevent clogging.
    • Airlock Efficiency: The valve should provide a reliable airlock to prevent pressure drops within the system. Proper airlock functionality ensures that dust is efficiently removed from the collector without disrupting the overall system pressure.
  2. Regular Inspection for Wear and Leaks:

    • Check for Component Wear: Regularly inspect the valve for signs of wear and tear. Components such as flanges, shafts, and seals should be checked for damage or degradation, as these can lead to leaks and reduced efficiency.
    • Leak Detection: Implement routine checks for leaks around the valve. Addressing leaks promptly can prevent reduced system performance and minimize potential operational disruptions.
  3. Evaluate Valve Options:

    • Automatic vs. Manual: Consider the benefits of automatic valves over manual ones. Automatic valves can provide power and maintenance savings and enhance the consistency of dust removal. They can also integrate with automated control systems for improved efficiency.
    • Power and Maintenance Costs: Analyze the total cost of ownership, including power consumption and maintenance requirements. Automatic valves may offer long-term cost benefits by reducing manual intervention and optimizing performance.
  4. Integration with Control Systems

    • Automation and Monitoring: Integrate the discharge valve with your control systems for real-time monitoring and performance management. Automated systems can provide valuable insights into valve operation, detect issues early, and facilitate proactive maintenance.
    • Data Collection and Analysis: Utilize data collected from control systems to analyze valve performance and identify trends. This information can help in making informed decisions about maintenance schedules and system adjustments.

While these considerations might seem fundamental, neglecting them can lead to significant challenges and increased costs. Addressing the dimensions, placement, and operational aspects of the dust collector and its components with careful planning and attention to detail can enhance the efficiency and longevity of your dust collection system. By prioritizing proper installation, maintenance, and monitoring, you can avoid common pitfalls, reduce downtime, and ensure that your dust collection system remains a reliable and effective component of your process equipment.

Investing time and effort into these preparatory steps will pay off in the form of a smoother installation process, improved system performance, and reduced long-term costs

Ensuring Effective Dust Collection System Management | Aerodyne

Posted by Tom Hobson on Jun 28, 2024 10:15:00 AM

A common problem that the dust collection industry faces is that once a dust collection system is installed, the records of the system are often lost or forgotten. Typically, the engineer who designed the system moves to another position or eventually retires, and the details are not passed along to the next person. This lack of continuity can lead to significant challenges when issues develop.

The Challenge of Lost Knowledge

When an issue arises, the new engineer responsible for fixing the problem often doesn't know what the unit was originally designed for or many other critical details. This knowledge gap can complicate troubleshooting and maintenance efforts. Sometimes, the equipment manufacturer has the specifications available, but these records are not always easy to locate. As a result, when experts are called in to help resolve the issue, the system often has to be reverse-engineered.

The Cost of Reverse Engineering

Reverse engineering a dust collection system means dedicating additional time and resources to figure out the original design. This process is not only time-consuming but also carries no guarantee that the recreated design will match the original specifications. Any discrepancies can lead to suboptimal system performance and increased operational costs.

The Impact of Undocumented Changes

Another common issue is that changes made to dust collection equipment are not always documented. Modifications can include adding or removing pickup points, altering ductwork, changing fans, or updating filters. All these adjustments can significantly affect the system's performance. Without proper documentation, these changes can create confusion and hinder effective problem-solving when issues arise.

Best Practices for Documentation

To mitigate these problems, Aerodyne suggests maintaining a comprehensive file that reflects the current design of the dust collection system. This file should include:

  • Up-to-date drawings
  • Airflow measurements
  • Pressure drop data
  • Equipment specifications

It's crucial that this file is accessible to multiple people within the facility. This accessibility ensures that if someone leaves or transitions to a different role, the information is not lost. A centralized, easily accessible record-keeping system can significantly improve the efficiency of maintenance and troubleshooting processes.

Implementing a Documentation Strategy

Here are some practical steps to ensure your dust collection system documentation remains current and accessible:

  1. Establish a Documentation Protocol: Develop a standardized procedure for documenting all aspects of your dust collection system. This should include creating detailed records of any changes made to the system.
  2. Regular Updates: Schedule regular reviews of the documentation to ensure it reflects the current system configuration. Any modifications should be promptly added to the records.
  3. Digital Record Keeping: Utilize digital tools and software to store and organize documentation. Digital records are easier to update, search, and share compared to physical files.
  4. Training and Awareness: Train staff on the importance of maintaining accurate records and how to access the documentation. Ensure that multiple team members are familiar with the documentation process and location.
  5. Backup Systems: Implement backup systems for digital records to prevent data loss. Regularly back up files to secure locations.

Conclusion

Effective documentation is vital for the smooth operation and maintenance of dust collection systems. By keeping detailed and accessible records, facilities can avoid the pitfalls of lost knowledge and undocumented changes. This proactive approach ensures that when issues arise, they can be addressed swiftly and accurately, minimizing downtime and maintaining optimal system performance.

Pneumatic vs Motorized Double Dump Valves | Aerodyne

Posted by Tom Hobson on Jan 29, 2021 9:45:00 AM

Double dump valves are available in both motorized and pneumatic actuation. To figure out which would be better for you we need to consider your application. A double dump valve is really two (2) valves with flapper plates in series controlled by the same mechanism. At least one of the flapper plates is closed at all time. The main things we need to know are the pressure, temperature, and flow rates along with the area classification the double dump valve will go in.

Motorized Double Dump Valve

A motorized double dump valve uses a cam rotated by a motor and gearbox to open and close each of the dump valves in series. The cam is designed so that at least one valve is closed at all time, thereby providing an airlock. The cam also provides a certain amount of cycles each minute, which controls the amount of material that is available to pass through the valve.

Pneumatic Double Dump Valve

A pneumatic double dump valve uses one pneumatic cylinder on each dump valve to control the operation of it. A timer is used to control the cylinders. The timer cycles cylinders so that one valve is closed at all times.

Differences Between Pneumatic and Motorized Double Dump Valve

Pressure - Motorized double dump valves are limited in the amount of pressure they can handle. The cam drive doesn’t provide direct force on the flap plates. This means that higher pressures and weights will push the flap plate open. The pneumatic valve, however, provides direct pressure on the flap plate so it can handle higher pressures and weights.

Temperature – A motorized double dump valve has a gearbox and motor located next to the housing of the valve. At higher temperatures, this can cause issues with the grease in the gearbox and motor. Also, the cam drive uses wear plates that might degrade faster at higher temperatures. The pneumatic valve, however, can be supplied with high temperature seals on the pneumatic cylinder.

Material Flow Rates – Unlike a rotary valve, which is continuously passing material through, double dump valves fill one chamber while emptying the other. This significantly cuts down on the flow rate through the valve. A motorized double dump valve size is limited due to the cam design. A spool piece cannot easily be installed to increase the volumetric flow through each chamber. While with a pneumatic design, each flap plate is controlled by its own pneumatic cylinder, a spool piece can easily be installed to allow additional material to flow through.

Area Classifications – The electrical classification of the area the valve is being installed can also effect the valve selection. A pneumatic valve has very few electric parts and can be designed to be intrinsically safe. A motorized unit has an electric motor, so the motor must be selected to for the area classification.

When selecting the best double dump valve for your application, look at the pressure, temperature, material flow rate, and area classification.

How to Clean Various Dust Collectors | Aerodyne

Posted by Tom Hobson on Nov 30, 2020 9:45:00 AM

When you have a dust collector capturing valuable material, you often have to regularly clean the dust collector to remove the material and if it is perishable, remove it before it contaminates the other material. Some dust collectors are easier to clean than others.

Wet Scrubbers

Wet Scrubbers are pretty much self-cleaning. Since they use water to capture the dust, it pretty much washes the walls and internals regularly. The main issue with wet scrubbers are that if you are trying to use the material (whether in the process or as a product) then you will need to remove it from the water stream (unless having it in a water stream is desirable).

Cyclones

Cyclones are very low maintenance. Since they use centrifugal motion to remove the material, there isn’t much buildup inside the cyclone. So there really aren’t many places to build up. Designing the vessel with access doors will help keep the cleaning easy. Aerodyne’s horizontal cyclone has a unique design that allows you access to the whole cyclone through its back plate.

Fabric Filters

Fabric filters collect the material on the filters (bags/ cartridges). This builds up a layer of material which remains on it for the life of the filter. During cleaning, the material falling off might have recently been captured or material that has been on the filter for an extended period of time. This could contaminate the material being collected.

  1. Baghouses require the bag to be removed in order to be cleaned or replaced. Often times this is a very time consuming process and can often require workers to enter the baghouse. If contamination is a serious concern, baghouses should not be used.
  2. Cartridge collectors are much easier with replacing the cartridges. Often times this can be done in minutes compared to hours of a baghouse. So you can remove the cartridges, clean them and re-install. This will allow you to clean or replace the filters after each batch, thereby minimizing any contamination.

One option is to install a cyclone dust collector as a pre-filter before your baghouse or cartridge collector. The cyclone will capture the majority of the material without contaminating it for use in your process / product. While the smallest fines will then be captured in the baghouse / cartridge collector for disposal or treatment. This allows you to capture as much of your valuable material with minimal cleaning / contamination while also providing the high removal efficiency for the environment.

Air Velocities and Your Ductwork Design | Aerodyne

Posted by Tom Hobson on Sep 21, 2020 1:49:35 PM

When designing a dust collection system, the ductwork is like the highways of the system. They allow the dust to move from the area of production to the dust collector. The dust should move fast enough so it doesn’t fall out while not moving too fast to cause undue wear and pressure drop. What this means is when you are designing your dust collector ductwork, pay attention to the ductwork diameters. When picking the ductwork diameters throughout the system, make sure the velocities correlate with the design velocities shown below.

Low Velocity Causes Dust Build-Up

A velocity that is too low will cause major issues in your ductwork. Dust will fall out and begin to pile up in the ductwork. This will do three (3) things:

  • The dust builds up, decreasing the area of the ductwork, until the open area is large enough to get the velocity back up within the range to prevent further dust buildup.
  • Dust buildup will increase the weight of the ductwork, and could cause issues with the support of the ductwork.
  • If the dust is explosive, the dust buildup creates fuel for an incident and could cause serious problems.

The table below is from the Industrial Ventilation Booklet (5-1) and gives the velocity ranges of various applications and dusts.

Installing Explosion Vents Indoor vs Outdoor | Aerodyne

Posted by Tom Hobson on Aug 31, 2020 9:30:00 AM

When protecting vessels from explosions, one of the most common ways is to install explosion vents. The explosion vent is an engineered weak spot in the vessel that fails when the internal pressure reaches a certain point. This failure allows the pressure to be released in a controlled way so that the entire vessel doesn’t explode. The explosion vent needs to be installed so that the venting is away from any equipment, walkways, roads, picnic areas, etc.

Explosion vents are primarily used when the vessels are located outdoors, however they can be used indoors, if certain criteria is met. To install an explosion vent indoors, the vessel has to be located by an exterior wall. The vent would then be ducted through the wall, so in case of an explosion it is directed outdoors. An indoor explosion vent will usually need to be larger than an outdoor explosion vent. This is due to additional combustion of material in the duct and the inertia of the air mass in the ductwork.

The following is an explanation taken from FM Global 7- 76 Section 3.1.8

During the early part of the venting process, unburned dust is ejected into the duct ahead of the flame front from the vessel. When the flame front moves into the duct, dust starts to burn within the duct and generate additional combustion products. Those combustion products expand in ALL directions, thus slowing down or even reversing the flow out of the vessel and the pressure builds up within the vessel.

Inertia of the air within the duct also increases explosion pressure within the protected vessel. When the explosion vent opens and combustion gases first start flowing into the duct, those gases must push all the air out of the duct. During the time required to eject the air, the pressure continues to grow within the vessel because the combustion gases are obstructed from reaching the open atmosphere. In a long duct, that mass of air can delay the venting of the combustion gases enough to significantly increase the pressure in the vessel.

So if you’re installing a vessel indoors and you want to vent it outside, keep it as close to the outside wall as possible.

Do Cyclones Replace Dust Collectors (Baghouses, Wet Scrubbers)?

Posted by Tom Hobson on Jul 24, 2020 9:14:12 AM

In most applications, cyclones do NOT replace baghouses, cartridge collectors, wet scrubbers, electrostatic precipitators, etc. Modern air pollution regulations require dust collectors to provide greater removal efficiencies in the PM2 and PM10 than most cyclones can provide.

How Cyclones work?

Cyclones collect dust by having the contaminated air enter (usually on a tangent) and spin around the cyclones walls until they get to the bottom. The air then reverses and spins up the middle of the vessel and leaves from the top, while the dust falls into the hopper.

The centrifugal forces on the particles and droplets, force them out towards the walls and away from the air exiting the center of the vessel. Cyclones provide high removal of the larger, heavier dust particles and moisture droplets.

The Benefits of Cyclones

Cyclones remove very high percentages of the larger, heavier particles. This means they often remove as much as 80%-95% of the total particles. However the removal efficiency of the smaller, lighter dust isn’t very high. The PM2 and PM 10 particulate will often get through the cyclone in high enough concentrations that the system won’t comply with state, local, and federal standards.

When installed in front of a dust collector (baghouse, cartridge collector, etc.) as a pre-filter, they significantly reduce the loading on the primary dust collector. This helps extend the operational life of the dust collector, increase removal efficiency, and decrease maintenance. Cyclones are often used to lower the loading on a dust collector (baghouse, cartridge collector, wet scrubber). The cyclone removes the large material, allowing the dust collector to get the high removal efficiency on the PM 2 and PM 10 particulate.

Why Is Particle Size Distribution Important? | Aerodyne

Posted by Tom Hobson on Jun 29, 2020 10:30:00 AM

There are multiple ways to collect dust from the air. The most common are:

The Important of Particle Size

The particle size of the dust is important in all three of these techniques. Basically the larger the dust particles are the easier it is to capture. And inversely, the smaller the particle is the harder it is to capture, which means it’s more likely to pass through the dust collector and out of the exhaust. Bags and filters build up a dust layer that allows air to pass but prevents particles from passing. Cyclones use centrifugal motion to capture particles, which means the larger and heavier the particle is the faster it spins out of the air-stream. Wet scrubbers use water droplets to increase the particle size of the dust, thereby making them easier to capture.

Particle Size Distribution

What this means is that to figure out how effective your dust collector is, a particle size distribution is required. For example, cyclones have a removal efficiency curve that tells you what percentage of particles will be removed at a certain particle size. This can be used to calculate the total removal efficiency when a particle size distribution is provided. Filter bags and cartridges get high dust removal down to around 1 micron in size; however, if most of your dust is sub-micron in size, they will not provide high removal efficiency. And wet scrubbers can be used to increase particle size, but the design must take into account the particle size.

So one of the first steps to correctly select and design a dust collection system is to run a particle size distribution test. This will allow you to pick the best equipment for your application and to make sure it will provide the removal efficiency you require.

Dust Collector: Signs You Need a Pre-Filter | Aerodyne

Posted by Tom Hobson on May 27, 2020 9:04:42 AM

Many dust collectors spend their time operating far below their potential.  Whether the system was designed incorrectly, the process has changed, slow maintenance, or a combination of these, the dust collector isn’t operating at its finest.    One possible solution is to install a pre-filter before your dust collector to help your dust collector to be all it can be!

The following are some signs that your dust collector isn’t operating up to par and you should look at installing a cyclone pre-filters

Filter Collectors (baghouse, cartridge collector, HEPA filters, etc.)

  1. There is a high pressure drop across your filters. This is caused by the dust building up on the filters and not being cleaned off fast enough.  The high pressure drop causes the fan to pull less air to compensate, thereby letting more dust out on to the shop floor.
  2. Filters are being replaces too fast! The most common filter failures are by developing holes or plugging up.  Both failures are tied to high dust loadings. 
     
    1. One of the ways holes develop is filter cleaning. Pulse-jet dust collectors use high pressure air blown down through the center of the filter to expand the filter off its support structure.  When the pressure disappears the filter returns to its normal size, causing the top layer(s) of dust to fall off the filter.  This regular expansion and contraction will cause holes and tears in the fabric, which then let unfiltered air and dust through the unit. 
    2. Plugging of the filters happens with “Tough” dust or a deficiency of cleaning of the filters. As the filters plug up, the removal efficiency will actually get better because very little air will get through, but this will cause dust to escape from the pickup points  as less and less air is pulled through the system.  So the dust collector system will not be doing the job it is supposed to do.
  3. Valuable product or raw material is being disposed in the dust collector waste due to contamination. As stated above, filters build up dust layers to provide the removal efficiency.  Those filters will retain the material over time.  If the material is valuable, this can be a lot of money that is going to waste.  Pre-filters will allow the material to be collected and used in the process or product before it can be contaminated in the filters.

Wet Scrubbers

  1. Do you have a high cost of water treatment and disposal of the scrubber blowdown? When wet scrubbers capture particulate, slurry is formed.  This slurry will then have to be disposed.  It will often be sent to a water treatment plant.  The water treatment plant might be dedicated to the facility or municipal.  Either way, additional costs are added to treat the slurry before it is disposed of or reused.  These costs are usually much more than disposing of dry material.  One reason being that dry material weighs much less because there isn’t any water added and the other being that regulations prevent slurries from being put into landfills, etc.  A pre-filter removes a portion of the material before it is put into slurry, thereby saving costs on waste water treatment.
  2. Similar to above, since wet scrubbers form slurries, any valuable material collected in the wet scrubber will be in that slurry. So unless the desired state of the material is within the slurry, it will have to be processed to make it useful.  This means additional steps (and expense) are required to recycle the material.  A cyclone pre-filter removes the material dry, before it is in slurry, thereby saving costs.

So before you decide to purchase a new dust collector, look into the benefits of installing a cyclone pre-filter.  You just might save yourself money!

How To Determine the Cost of a Cyclone - Part 5 | Aerodyne

Posted by Tom Hobson on Apr 24, 2020 1:29:51 PM

When selecting the cyclone for a dust collection process, there are different factors affecting sizing and cost of the cyclone.  The cyclone should be sized to compliment the airflow of the system and the required dust removal efficiency.  Process conditions will dictate suitable materials of construction as well as any special design requirements.

Part 5: Cyclone Orientation (Horizontal vs Vertical)

The cyclone orientation can affect pricing and cyclone selection.  A vertical cyclone has slightly better removal efficiency than a horizontal cyclone.  Horizontal cyclones are much shorter so they can often fit in spaces where vertical cyclones can’t be placed.  The horizontal cyclone can be accessed easier for cleaning and is easier for installing explosion vents when needed.  However, horizontal cyclones have limitations with high concentrations of dust and cost more than vertical cyclones.

In summation, cyclone design and costs are based on the size and construction required in your specific application.  Special applications can require costly equipment and design changes that will increase the cyclone cost significantly.  When selecting a cyclone for your application, be sure to include all the factors in to your cost estimate so you are can accurately determine your budget.
