Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a novel bag dust collector. Background Art

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] The existing bag dust collector is used to filter the gas with high dust content by arraying the filter bags, and adopts pulse self-cleaning. In the filtering process, the air intake direction of the dust-containing gas is certain, and the flow rate is large under the action of the external induced draft fan, which causes the filter bag at the air inlet to be seriously blocked and easily damaged due to the large impact force, resulting in uneven blockage of the filter bag as a whole, thereby affecting the filtering efficiency and effect of the device. Therefore, a new bag dust collector is urgently needed to solve the above problems. Utility Model Content
