The utility model discloses a novel rotary blowing ash removal device for a bag-type
dust collector, and relates to the technical field of
air pollution control. The device comprises a pulse valve, a driving device, a gas
storage tank, a rotary blowing mother
pipe and a rotary blowing
pipe, the driving device and the rotary blowing mother
pipe are connected through a middle connecting pipe and a
metal corrugated pipe, the two ends of the
metal corrugated pipe are connected with the middle connecting pipe through
flange bolts, the rotary blowing pipe and the middle connecting pipe are connected and fixed through a pull rod, and the pull rod is connected with the gas
storage tank. The rotary blowing device is characterized in that holes are uniformly distributed in the rotary blowing pipe, and the hole
diameter is 76mm * 50mm. According to the utility model, by adjusting the structure of the rotary blowing deashing device, the blowing
system is prevented from being damaged due to errors in mounting and manufacturing precision, meanwhile, the rotary blowing deashing device is more convenient to overhaul and maintain, and the performance of the whole dedusting
system is improved.
