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.

A dust collector is provided, which includes a housing, a filter screen, and a spiral air director. The housing is provided with an air inlet, an air inlet channel, an air outlet channel, an air outlet, and a dust collection chamber. The dust collection chamber is in communication with the air inlet and the air outlet through the air inlet channel and the air outlet channel, respectively. The filter screen is disposed in the air outlet channel. The spiral air director is disposed in the air outlet channel and located on at least one side of an air inlet side and an air outlet side of the filter screen. Air flow flowing through the air outlet channel is directed by the spiral air director to form a swirling air flow.
