PROBLEM TO BE SOLVED: To provide a cyclone type dust collector removing dust in air by centrifugal separation, having both high dust collection capacity and low pressure loss. SOLUTION: The dust collector 1 includes a vane train 4 at one end in the axial direction of a cylinder 2, a discharge port 5 at the other end, and a guide plate 7 between the vane train 4 and the discharge port 5. When the air containing dust flows into the dust collector 1, the vane train 4 turns the air flow and causes a swirling flow. By the centrifugal force caused by the swirling flow, dust is separated outwardly, dropped and collected. The guide plate 7 prevents direct flow of the air flow having passed through the vain train 4 toward the discharge port 5, and guides the air flow further outwardly from the vicinity of the axis. This causes a further outward swirling flow to promote the separation of the dust. Extreme narrowing of an air duct is not needed, thus causing little increase in the pressure loss. Thus the dust collector can have both high dust collection capacity and low pressure loss. COPYRIGHT: (C)2010,JPO&INPIT
