Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology, specifically relating to a bag filter with a high-efficiency dust removal structure. Background Technology

[0002] Baghouse dust collectors, also known as bag filters or filter dust collectors, are a type of dry, high-efficiency dust removal equipment widely used in various industrial fields. Their core working principle is to use bag-type filter elements made of woven fiber material to filter dust-laden gas, capturing dust particles through the filter bags, thereby achieving air purification.

[0003] The main components of a baghouse dust collector include filter bags, a dust hopper, and a cleaning system. When dust-laden gas enters the dust collector, large dust particles settle into the dust hopper due to gravity, while fine dust particles are captured by the filter bags. A layer of dust gradually accumulates on the surface of the filter bags, forming an initial layer that effectively improves filtration efficiency. As dust accumulates, the resistance and efficiency of the dust collector increase. At this point, the cleaning system is needed to remove the accumulated dust from the filter bags to maintain efficient operation.

[0004] Although baghouse dust collectors can remove dust, they may not be able to completely remove odor substances, resulting in the exhaust gas still having an odor. At the same time, even if the filter bags have high filtration efficiency, it is difficult to completely block all dust particles, especially extremely fine dust particles that may penetrate the filter bags and escape.

[0005] This utility model addresses the above-mentioned problems by providing a bag filter dust collector with a high-efficiency dust removal structure that can filter odorous gases. Utility Model Content
