Acrylic needle-punched felt dust filter bag is a key part of the bag filter operation process, usually the cylindrical filter bag is vertically suspended in the filter bag. The fabric and design of the dust filter bag should strive for high-efficiency filtration, easy dust stripping and durability. In pulse and air box pulse dust collectors, dust is attached to the outer surface of the dust bag. When the dust-laden gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas enters the filter bag through the filter material. The cage inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing, at the same time it facilitates the removal and redistribution of the dust cake.
