[0002] Cartridge dust collectors are composed of filter cartridges as filter elements or use pulse jets. Cartridge dust collectors can be divided into oblique insertion type, side-mounted type, hanging type, and top-mounted type according to the installation method. Cartridge dust collectors can be divided into long fiber polyester cartridge dust collectors, composite fiber cartridge dust collectors, antistatic cartridge dust collectors, flame retardant cartridge dust collectors, membrane cartridge dust collectors, nano cartridge dust collectors, etc. according to the cartridge material.

[0003] The problem with the prior art is that workers engaged in the welding industry will encounter a problem of being disturbed by smoke and dust at work. Workers are in a smoke and dust environment for a long time, which will cause great harm to their health. Moreover, the smoke and dust are discharged into the atmosphere, which will pollute the environment and is not environmentally friendly. For the health of workers and environmental protection, a dust collector specifically for smoke and dust is needed. The filter cartridge is a dust catching device in a filter cartridge type dust collector. Smoke and dust have a certain corrosive effect on the filter cartridge. However, the filter cartridges inside the existing dust removal equipment are disposable products and need to be replaced after a certain period of use, which increases the maintenance burden of the factory. In order to facilitate the cleaning of the filter cartridge and extend its service life, an anti-corrosion and environmentally friendly filter cartridge for a filter cartridge type dust collector is proposed, which is convenient for the staff to clean while increasing the corrosion resistance of the filter cartridge and extending its service life.
