Which industries can the dust filter bag be used in?

1. The brewing industry uses bag filters to separate grains from sugar, remove proteins from the process that slows down the fermentation process, and remove any unwanted solids before bottling. This requires different packaging bags, because if used in the early stages of brewing, the use of tighter packaging bags at the end of the process will adversely affect the beer

2. The bag filter used in the mining and chemical industries must be stainless steel and often carry ASME stamps. These bag filters and processes must meet strict regulations and often must be able to filter sub-micron particles.

3. To remove contaminants from the water, bag filters and other purification methods are often used, such as the use of activated carbon or reverse osmosis. Filtering wastewater for reuse means having the ability to eliminate pollutants of various types and sizes to comply with regulations and ensure safety. Industrial bag filters are used to filter water according to the type and size of particles in the water.

4. Industrial bag filters are often used in the food and beverage industry due to their low cost and high reliability.

The material of the dust filter bag

Fabric filter bags (sometimes called envelopes) are oval or round tubes, usually made of woven or felt material, with a diameter of 15–30 feet and a diameter of 5 to 12 inches. Depending on the chemistry and/or moisture content of the airflow, its temperature and other conditions, the bag can be made of cotton, nylon, polyester, fiberglass or other materials. The nonwoven material can be felt or film. The non-woven material is attached to the woven backing (scrim). The felt filter contains randomly placed fibers supported by a textile backing material (scrim). In membrane filters, a thin porous membrane is bonded to a scrim. High-energy cleaning techniques, such as pulse jet, require felt fabrics.

 

The woven filter has a definite repeating pattern. Low-energy cleaning methods (such as shaking or backflow air) can be used to woven filters. Various weaving patterns (such as plain weave, twill weave or satin weave) will increase or decrease the spacing between individual fibers. The size of the space affects the strength and permeability of the fabric. A tighter weave corresponds to low permeability and therefore captures fine particles more effectively. An anti-collapse ring is sewn on the reversing airbag to prevent agglomeration when cleaning energy is applied. The pulse jet filter bag is supported by a metal cage to keep the fabric tight. In order to extend the service life of the filter bag of the dust collector, a layer of PTFE (polytetrafluoroethylene) film can be adhered to the filter side of the fabric to prevent dust particles from embedding in the fiber of the filter medium.

 

In conclusion

In every industry that requires dust collectors, these bag filters are placed in the bag filter housing, with the purpose of purifying the waste water by removing solids. They are commonly used with many other products to treat industrial process water, wastewater, groundwater and cooling water. Generally, bag filters are used in situations where solid matter needs to be removed from liquids. The use of bag filters varies from industry to industry. If you are looking for a high-quality dust bag at a reasonable price,Jiangsu Aokai Environmental Technology Co., Ltd. will provide you with the best products.
