Description

Technical Field

[0002] Since the filter cartridge dust removal equipment uses the filter cartridge as the main filtering structure, it has good dust particle recovery performance and is widely used in industrial dust control in shipbuilding, automobile, casting, non-ferrous metal processing, light industry and medicine and other industries.

[0003] Usually the filter cartridge is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the equipment, it is filtered by the filter cartridge. Dust with large particles and high specific gravity settles due to gravity and falls into the bin and can be recycled.

[0004] However, when the gas containing fine dust passes through the filter cartridge, the dust can also be retained to purify the gas, but due to its fineness, it will continue to adhere to the outer wall of the filter cartridge, affecting the air permeability of the filter cartridge.
