Cyclone bag type dust collector for rotary chamber pulse jet system

The invention discloses a cyclone bag type dust collector for a rotary chamber pulse jet system. The cyclone bag type dust collector comprises an air tank, a compressed air tube, a solenoid valve, a pulse valve, an air lock, a pressure difference transmitter and the like, wherein the air tank is connected to the solenoid valve, the pulse valve and an air nozzle through the compressed air tube so as to form a system for supplying compressed air to the air nozzle by an air source; a filter bag is nested in an inner barrel of the cyclone bag type dust collector; the filter bag is divided into multiple areas by chamber separators, so that chamber ash removal is conveniently performed; a rotating door rotates around an intermediate shaft, and the other end of the rotating door overlaps on a door shield so as to form a closed space with the chamber separators and the door shield; a stepping motor is inlaid on the lower side of the intermediate shaft; and the pressure difference transmitter is used for detecting pre
