Description

Technical Field

[0001] The utility model relates to the technical field related to dust removal equipment, in particular to a pulse filter cartridge ventilation and dust removal device. Background Art

[0002] At present, cartridge dust collectors, as important waste gas treatment equipment in the surface treatment industry, can effectively capture and filter smoke and waste gas, and ultimately achieve emissions in compliance with environmental protection policies.

[0003] After extensive searching, it was found that the Chinese patent announcement number is CN211676833U, which discloses a pulse filter cartridge dust collector with online dust cleaning. The pulse filter cartridge dust collector with online dust cleaning includes: a dust collector body, a filter cartridge, an air bag, a partition and a cylinder; a plurality of filter cartridges are evenly distributed in the dust collector body, and partitions are provided between the evenly distributed filter cartridges. The plurality of filter cartridges between adjacent partitions form a filter cartridge group, and the air bag is arranged on the outer top side of the dust collector body. A plurality of air blowing ports are provided on the air bag pipeline, and each air blowing port is placed above the filter cartridge. The cylinder is arranged above the exhaust port of the dust collector body. The utility model provides a pulse filter cartridge dust collector with online dust cleaning.
