Abstract
A scrubber removes dust from an exhaust gas. The scrubber includes a casing having an exhaust gas inlet and an exhaust gas outlet, an impeller housed in the casing and supported by a shaft, and a cleaning liquid supply tube for ejecting a cleaning liquid by which the dust contained in the exhaust gas is captured. The scrubber further includes a plurality of protrusions provided around the impeller such that the exhaust gas and the cleaning liquid which are discharged from the impeller impinge upon the protrusions.
