The utility model discloses a cloth bag type pulse dust collector. The cloth bag type pulse dust collector comprises a support and is characterized in that a dust collection frame is arranged at the upper end of the support, and an ash hopper communicated with the dust collection frame is arranged in the support; a cloth bag dust collection mechanism is movably connected onto the dust collection frame and movably mounted in the dust collection frame through a lifting mechanism; a rotating plate provided with a pulser and an air accumulation cavity is mounted at the upper end of the dust collection frame, and a draught device is communicated with a draught pipe which is communicated with the air accumulation cavity; an air inlet pipe is communicated with the side wall of the dust collection frame. The cloth bag type pulse dust collector is simple in structure, ascending and descending of a cloth bag frame are realized by the aid of the lifting device, and rotation of the draught pipe and cloth bags is realized by the aid of the rotating plate; further, the plurality of dust collection cloth bags of different specifications are arranged in the cloth bag frame and used for collecting dusts of different particle diameters, so that using one collector for collecting various dusts is realized, equipment cost is reduced, and production cost is reduced as well.
