Description

Technical Field

[0001] This utility model belongs to the technical field of baghouse dust collectors, and specifically relates to a baghouse dust collector for purifying waste gas. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.

[0003] A search revealed a pulse jet baghouse dust collector for waste gas purification, patent publication number CN214019733U. The collector includes a housing, an mounting plate on one outer wall of the housing, an air manifold on the upper surface of the mounting plate, an electromagnetic pulse valve on the upper surface of the air manifold, and a blowpipe at the other end of the electromagnetic pulse valve. Both sides of the inner wall of the housing are fitted with locking mechanisms, and a tube sheet is mounted on one side of each locking mechanism. Grooves are provided on both outer walls of the tube sheet, and venturi tubes are spaced apart on the lower surface of the tube sheet. Dust filter bags are mounted on the lower surface of the venturi tubes. A dust hopper is located at the bottom of the housing, and supports are installed on both sides of the lower surface of the housing. This effectively purifies waste gas, improves its secondary utilization, and allows for easy replacement of the dust filter bags.

[0004] In existing technologies, a dust collection hopper is fixedly connected to the bottom of the bag filter. When cleaning the dust collection bags, the falling dust easily accumulates on the inner surface of the dust collection hopper, causing blockage at the discharge point and resulting in poor performance. Therefore, it is necessary to design a waste gas purification bag filter to solve the above problems. Utility Model Content
