Filter cartridge dust collector is a kind of filtering dust removal equipment, which is composed of filter cartridge as filter element or pulse jet dust removal equipment. Filter cartridge dust collector has many advantages, such as compact structure, small volume, high dust removal efficiency, good dust collector effect, convenient manual maintenance and so on. At present, the application scope of this equipment in the industrial production field has become wider and wider. Its working principle is as follows: after the dusty gas enters the dust collector from the air inlet, the air flow speed slows down, the coarse particles leave 76 and settle in the dust collecting chamber, the fine dust is blocked on the surface of the filter cartridge when passing through the filter cartridge with the air flow, and the crystalline gas is discharged from the air outlet; When the ash layer on the surface of the filter cartridge is thick, the pulse controller will issue a command to open the blow valve. The compressed air in the air bag will be ejected at high speed through the blow pipe, and the surrounding air several times of the ejected air volume will be induced to enter the filter cartridge and be ejected rapidly from the inside to the outside. The dust on the surface of the filter cartridge will be blown down into the dust collection chamber and finally discharged from the ash hopper.
