The present invention relates to an air re-circulation road sweeper capable of reducing air pollution and improving efficiency of road dust suction. The present invention provides an air re-circulation road sweeper which includes a blower (1410), a suction unit (1440) for sucking dirt on the road surface using the vacuum pressure provided from the blower, a hopper portion (1300) for storing the dust from the suction unit, a circulation intake portion (1420) where the air from the hopper portion returns to the blower, a circulation exhaust portion (1600) which provides the discharged air from the blower to the suction unit, an exhaust duct portion (1430) discharging exhaust air as discharged exhaust air from the blower to the outside, and a damper section (2000) for splitting air from the blower to one or more of an exhaust air discharge or the circulating exhaust. |
