Dust recovery mechanism and cartridge filter

Abstract

The invention discloses a dust recycling mechanism and cartridge filter. The filter comprises a filtering box body, a filtering chamber is arranged in the filtering box body, an air inlet pipeline communicated with the filtering chamber is arranged on the side wall of the filtering box body, and an air purifying chamber communicated with the filtering chamber is arranged at the position, located at the top of the filtering chamber, of the filtering box body, a ventilation pipe is arranged between the filtering chamber and the air purifying chamber, a filtering mechanism is arranged in the filtering chamber and comprises a positioning plate frame arranged in the filtering chamber, a plurality of filter cartridges are arranged on the positioning plate frame, and a pulse cleaning mechanism for performing pulse cleaning on the filter cartridges is arranged in the filtering box body, and an air outlet pipe is arranged at the top of the air purifying chamber. The pulse cleaning mechanism is controlled to clean the filter cartridge, so that instant positive pressure appears in the filter cartridges, and swelling and micro motion are generated; dust deposited on a filter material falls into a dust hopper, and the dust in the dust hopper enters a dust collecting box, so that the filter cartridges can be automatically cleaned.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a dust recovery mechanism and a filter cartridge dust collector. Background technique [0002] With the improvement of people's living standards, the requirements for air quality are getting higher and higher, and dust collectors are widely used in electric power, chemical and other industries. Among them, after the filter material in the dust collector has been used for a period of time, a layer of dust has accumulated on the surface of the filter bag due to effects such as screening, collision, retention, diffusion, and static electricity. This layer of dust is called the first layer. , the first layer becomes the main filter layer of the filter material, relying on the role of the first layer, the filter material with larger mesh can also obtain higher filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistanc...
