A dust removal filter bag is a highly efficient dust-filtering material. It features good air permeability, high dust removal efficiency, and certain resistance to acids, alkalis, and heat. During the weaving process, multi-side flocking is adopted to increase the thickness of the fabric, making it elastic and achieving excellent dust removal performance with a dust removal rate of up to 99.999%. Made from polyester short fibers or long fibers, the filter bag has a service life generally 4-6 times that of glass fiber fabrics. It boasts good air permeability, high dust collection efficiency, easy dust cleaning, and a dust removal efficiency of up to 98.99%.
The filter bag is the core component during the operation of a bag dust collector. Typically, cylindrical pulse filter bags are vertically suspended in the dust collector. The dust-laden gas enters the dust collector through the air inlet and passes through the baffle plate of the ash hopper, where part of the large-particle dust in the gas is separated by inertia and falls directly into the ash hopper. The dust-laden gas then enters the filter bag filtration zone of the chamber, where the vast majority of the dust is trapped on the outer surface of the filter bags, while the clean gas passes through the filter material into the interior of the filter bags. The purified gas enters the upper chamber through the filter bag openings and is then discharged through the air outlet. The cage inside the filter bag supports the filter bag to prevent it from collapsing, while also assisting in the removal and redispersion of the dust cake.
