A scrubber including a casing having an exhaust gas inlet and an exhaust gas outlet. An impeller is mounted in the casing, and the impeller is rotatable about its own axis. An exhaust gas can be introduced into the center of the impeller through the exhaust gas inlet of the casing. A cleaning liquid discharge nozzle is positioned at the center of the impeller for spraying a cleaning liquid in the impeller. Also, a baffle member is spaced apart from and surrounds the impeller. A mixture of the exhaust gas and the cleaning liquid exiting the impeller impinges on the baffle member. The cleaning liquid discharge nozzle is provided inside and rigidly connected to the impeller so as to rotate together with the impeller. The nozzle has a plurality of cleaning liquid discharge orifices extending radially through a cylindrical wall thereof to discharge a cleaning liquid into the impeller.
