[0002] Bag type dust collector is a dry type dust filtering device, which is suitable for capturing fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag type dust collector, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. The gas containing fine dust is filtered when passing through the filter material, so that the gas is purified.
