The MC-II pulse dust collector is a new type of pulse dust collection equipment improved on the basis of the MC-I pulse dust collector. In order to further improve the MC-I pulse dust collection equipment, the original pulse dust collection equipment has been modified. The modified MC-II pulse dust collection equipment retains the high purification efficiency, large dust processing capacity, stable performance, easy operation, long filter bag life, and low maintenance workload of the MC-I pulse dust collection equipment. Moreover, the pulse dust collection equipment has been modified in terms of structure and pulse valve, solving the problems of outdoor placement of pulse dust collectors and low compressed air pressure. This pulse dust collection equipment is suitable for mechanical, metallurgical, rubber, flour, chemical, carbon, building materials, mining and other units.
