IPC: F24F7/007
Filed: 1988-06-28
Abstract: PURPOSE:To suck and purify flue gas before it is dispersed and to prevent contamination of the interior of a room by a method wherein a title device is provided with a suction port for a flow, a fan to feed a flow to a discharge port, and an annular discharge port situated around the suction port and discharging the flow, and a purifying device is located between the discharge port and the fan. CONSTITUTION:With a fan 5 run, a flow is sucked through a suction port 4 and discharged through a discharge port 7, and the flow runs toward the outside along a guider 9. Since the discharge port 7 surrounds the suction port 4, the inner side of an annular flow running out from he discharge port is brought into a negative pressure state. With the progress of flows toward a downstream, the flows are mutually drawn to the inner side and join together at a position B, and the suction port 4 sucks a flow in the vicinity of a position B. Namely, the position of suction is moed from the position A to the position B. A moving distance H is changed according to an out angle theta of the guider 9 but the H is maximized at approximately 45 deg.. While a flow sucked through the position B passes a passage 11a of a purifying device 11, impurity, e.g. smoke, is removed, the flow is discharged through the discharge port 7 again.
