[0002] The bag type dust collector is a dry type dust filtering device, which is suitable for capturing fine, dry and non-fibrous dust.
[0003] The filter bag is made of woven filter cloth or non-woven felt, which utilizes the filtering effect of the fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag type dust collector, the dust with large particles and specific gravity settles down due to the action of gravity and falls into the ash hopper. The gas containing fine dust is filtered through the filter material, and the dust is blocked, so that the gas is purified.
[0004] The outer shell of the bag type dust collector includes a cover plate, a top plate, a middle box body and an ash hopper. The top plate mainly serves as the top covering structure of the dust collector and is usually designed with an air inlet to allow dust-containing gas to enter the interior of the dust collector.
