Dust bags is the heart of bag filter during its operation. Usually, the cylindrical pulse filter bag is suspended vertically in the filter. Dust-containing gas enters the filter from the air inlet and passes through the deflector of the ash hopper, so that some large particles of dust in the gas are separated by inertial force and directly fall into the ash hopper. Dust-containing gas enters the filter area of the filter bag of the box, most of the dust is trapped on the outer surface of the filter bag, while clean gas enters the filter bag through the filter material, and the purified gas enters the upper box through the filter bag opening. The cage inside the filter bag is used to support the filter bag, prevent the filter bag from collapsing, and help to remove and redistribute the dust cake.

P84 high temperature resistant dust removal bag

P84 needled felt is made of P84 fibers by three-dimensional needling. P84 fiber (polyimide fiber) has good high temperature resistance, which can reach 260℃, and the cross section of P84 fiber is irregular leaf-shaped, which can greatly improve the filtration effect. The fiber itself has certain hydrolysis resistance and oxidation resistance. The product has good temperature resistance and filtration effect, and is widely used in complex working conditions such as concrete mixing, cement, garbage incineration and coal-fired boilers.

Teflon dust bag

Teflon needled felt is a kind of filter material made of Teflon (Teflon fiber) by three-dimensional needling. Polytetrafluoroethylene fiber is a polymer linear structure, so it has strong temperature resistance, wear resistance, corrosion resistance and chemical stability, and is widely used in various harsh flue gas filtration environments such as steel, electricity and garbage incineration.
