Patent ID: 11260334

Abstract:
An object of the present invention is to provide a dust collector including a pulse jet type dust removal mechanism capable of uniformly removing dust over the entire length of a cylindrical filter without increasing the pressure loss of the cylindrical filter; and a dust removal method for such a dust collector. The dust collector of the present invention is a dust collector including a pulse jet type dust removal mechanism for removing dust adhered to cylindrical filters, in which the pulse jet type dust removal mechanism includes: a first discharge section having first discharge nozzles for discharging pulse jets from first end side openings of the cylindrical filters toward inside of the cylindrical filters; and a second discharge section having second nozzles for discharging pulse jets from second end sides of the cylindrical filters toward openings on the first end side of the cylindrical filters, and the second nozzles for discharging are each provided on a tip side of a pipe line extending from the first end side to the second end side of the cylindrical filter.
