  • Dusting Across Industries

    When I was younger I used to help my dad out at his job during the summer, and sometimes still do. He happens to be a farmer, so I did not get to spend a summer of luxury indoors in the air conditioning, but rather outside sweating under the sun. One of his favorite tasks to have me help with was stacking hay bales in the barn. This was a time consuming, labor intensive and intimidating task, and easy to push off on able-bodied teenagers. This project involved stacking hay...

  • Bag Houses Use Fabric as Filter

    Bag houses are highly cost-effective and efficient methods of dust collection, offering a typical fine particle capture rate of more than 99 percent. Common materials used to make bag houses include cotton, glass-fiber and synthetic materials. Like cyclone collectors, bag house collectors are incorporated into large dust collecting systems of industrial facilities, often located outside and connected to the interior through ductwork. Bag houses can be used in conjunction with cyclones when there are larger media that needs to be separated by the cyclone before the dirty air enters the...

  • Important Factors Regarding Bag Houses

    Bag houses are essential dust collection machines for capturing dust and other particles. Improper dust control can result in contamination of products and unfortunately even explosions. These hazardous events are why bag house maintenance is vital to the successful operation of a facility. To ensure ultimate proficiency of bag house the differential pressure must be carefully monitored. The differential pressure is a crucial gauge of determining the status of a bag house. When diagnosing any issues regarding a bag house analyzing the differential pressure is typically the first step. If...

  • Variations of Baghouses

    Baghouses are used for the removal of dust and dirty particles from the air. They are found in factories, and other large scale manufacturing workshops where a dust control system is needed. A proper and efficient dust collection system is essential for any industrial environment where airborne particles are common. Keeping the air clean is an important part of employee safety and well being as well as keeping the environment and work place clean and productive. Baghouses are one way that manufacturers use to keep their air at a healthy...

  • Dust Collecting Is More Than Just Sitting Around

Like the miniatures in my wall shadowbox, or the weird knickknacks my mom has been buying off EBay lately. Dust collectors. Ok, so I have a degree in playing with words, not in Industrial Engineering. It turns out dust collectors perform, in many manufacturing plants, one of the most...

Industry Information

Bag Houses

Bag houses, also spelled “baghouses” and also known as bag filters or fabric filters, are a type of dust collector, which is any system or machine that draw dust out of the air into a filter or separator. In this same group are equipment like air scrubbers, electrostatic precipitators, wet scrubbers, unit collectors and inertial separators. By removing contaminated air particles from the environment around them, bag houses and dust collecting systems like them improve air quality and worker health and safety. Bag houses, which trap dust particles using fabric filters, are popular for a number of reasons. For starters, they are easy to use and cost-effective; they typically exhibit a fine particulate capture rate of up to 99.9%. In addition, rather than disposing of the dust after collection, as scrubbers do, bag houses return it to the mix. There, the dust can be reused. Another advantage of baghouses is the fact that are more portable and flexible than other devices. Also, they require less horsepower than others to operate.

In addition to simple dust, baghouses commonly capture particles such as: concrete dust, wood dust, welding fumes and incinerator smoke. They can also separate and filter toxic media, explosive media and metalworking chips. They are popular in work environments including manufacturing facilities, workshops and plants. In particular, they are the preferred method of particulate emission control in hot mix asphalt plants. They are also useful to companies seeking to comply with OSHA regulation pollution codes without breaking the bank. Typical industries in which companies like these are involved include: agriculture, cement fabrication, chemical processing, coal handling, metal fabrication, pharmaceutical processing, recycling, waste incineration and woodworking.

Bag houses consist of ducts, a fan, a hopper, fabric filters, an outlet and an airlock. To pull contaminated air through the fabric filters, or bags, the fan creates a vacuum. The air enters through the ducts into the hopper, where the filters are housed. Here, the filters capture smoke, dust and other particles and let the clean air move freely through and out of an outlet at the top of the baghouse. The captured particles eventually settle into a routinely emptied airlock, found at the bottom of the hopper. As they settle, the dust particles accumulate on the fabric filters and build up to form a layer known as a filtering cake, filter cake or dust cake. The filter cake is an important and unique feature of the baghouse; it is used as a barrier that can catch extremely fine particulates. The filter cake must be carefully maintained, though, because if it is allowed to build up too much, it will clog the airway and become ineffective.

There are three main types of bag houses, each which maintains the filter cakes in different ways. First are reverse-air bag houses. To work, filtration is paused in a compartment about to be cleaned. (Reserve-air bag houses are compartmentalized so that filtering can continue in most areas, even at it is halted in one compartment during cleaning.) Then, clean air is injected into the baghouse in reverse direction, thus pressurizing the compartment and causing the filter bags to partially break down. This breakdown causes the filter cake to crack and fall into the hopper. Similarly, the next type of baghouses, reserve-jet bag houses, permit unbroken filter operation during cleaning, but they do not usually have compartments. In this case, the filter bags are cleaned when compressed air is sent through in short bursts via a compressed air manifold. Finally, mechanical shaker bag houses clean themselves using vibrations that shake the filter cake off of the filter and into the hopper. These vibrations are generated by a motor-driven shaft and cam. In addition, this cleaning process may be supplemented by a device known as a sonic horn. Sonic horns work by emitting low frequency, high intensity sound waves; these sound waves help sever the bonds between particles sitting on the filter media surface, and they also help with dust removal.

Bag houses are most often made from fiberglass, cotton and various synthetic materials. To determine the best bag house materials and configurations for your application, call a trusted dust collection professional today. Once you have your bag house, make sure to care for it properly by paying attention to the following factors of its performance: gas temperature, pressure drop, opacity and gas volumetric flow rate. Provided all of these elements are watched and corrected when wrong, you can count on your bag house to clean your air efficiently for many years to come.
