Description

Technical Field

[0001] The present invention relates to the field of cleaning and dust collection devices, and particularly to a gas box pulse bag filter for pollution prevention and control. Background Art

[0002] A gas box pulse bag filter for pollution prevention and control is a device used to remove pollutants from polluted gases, aiming to remove dust in polluted air, improve the environment, and reduce pollution.

[0003] The patent with the patent announcement number CN214809256U involves a dust collection box body, a dust accumulation box body, a top air inlet box body, an annular box wall, a pulse valve, a retractable vibration airbag, a cylindrical dust filter bag, and an airbag support. The dust collection box body is supported and installed on the top of the dust accumulation box body. The top air inlet box body is installed on the top of the dust collection box body. A diversion air inlet hole is opened on the top box wall of the dust accumulation box body. A top ring plate is fixedly installed below the diversion air inlet hole. The bottom of the top ring plate is connected and installed with a bottom ring plate through the cylindrical dust filter bag. The bottom of the bottom ring plate is installed with a funnel wall at the bottom of the ring plate. The bottom leak port of the funnel wall at the bottom of the ring plate is connected to the dust accumulation box body through a dust discharge valve. The annular box wall is installed on the inner side wall of the dust collection box body. The beneficial effect is that the patent can more effectively clean the dust on the filter bag by converting the pulse air pressure into the physical vibration of the elastic airbag.

[0004] In the above patent, although the patent can more effectively clean the dust on the filter bag by converting the pulse air pressure into the physical vibration of the elastic airbag, there are still problems. When impurities cannot be cleaned in time, they will block the pores of the filter screen, increasing the resistance of the gas passing through the filter screen and making the passing speed slower and slower. This will lead to a significant decrease in the overall filtration efficiency of the filtration device and a reduction in the amount of materials that can be processed per unit time.
