<P>PROBLEM TO BE SOLVED: To provide a cyclone dust collection device for separating and removing powder dust included in atmospheric air, which is capable of retaining a high dust collecting efficiency while retaining the setting space by reducing the pressure loss. Ž<P>SOLUTION: When air is introduced into the dust collection device 1, swirling flow is generated within an annular chamber 2 and the centrifugal force is applied to the powder dust in air. The powder dust descends while swirling along the inner wall surface of a cone-shaped tube 5 to fall into a dust collection chamber 6. When an axial flow fan 10 mounted within an exhaust chamber 8 is rotated and operated, the pressor action works and the still pressure in an exhaust port 9 rises higher than the pressure on an inner cylinder side, and as a result, the pressure loss as the dust collection device can be reduced. In this way, the dust collection device having the high dust collection efficiency while retaining the setting space by reducing the pressure loss can be provided. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
