Description

technical field

[0001] The invention relates to the technical field of environmental protection dust removal, in particular to a multi-stage filter dust collector. Background technique

[0002] The bag filter is a dry dust filter device, which uses the filtering effect of the filter material to filter the dusty gas to purify the gas; when the dusty gas is filtered through the filter material, the dust attached to the filter material continues to increase The ventilation effect of the filter material is significantly reduced, resulting in a reduction in the dust removal efficiency of the dust collector.

[0003] The traditional bag filter uses a first-stage filter bag for filtration. The concentration of dust-containing gas around the filter bag is relatively high, and the size of the dust particles is uneven. Some larger dust is easy to block the filter bag, thereby affecting the filtration efficiency.

[0004] In addition, the existing bag-type dust collector mainly uses d...
