Scrubber to remove solid particles from exhaust gases

摘要

A scrubber (20) comprises a casing (21) having an exhaust gas inlet and an exhaust gas outlet (28); an impeller (23) mounted in the casing (21), and which is rotated about its own axis, an exhaust gas introduced into the center of the impeller through the exhaust gas inlet of the casing; a cleaning liquid discharge nozzle (38) positioned at the center of the impeller (23) to spray a cleaning liquid in the impeller; and, a baffle member (30) spaced apart from and surrounding the impeller (23) on which a mixture of the exhaust gas and the cleaning liquid exiting the impeller impinges. The cleaning liquid discharge nozzle (38) is provided inside and rigidly connected to the impeller (23) to rotate together with the impeller. The nozzle has a plurality of cleaning liquid discharge orifices (39) extending radially through the cylindrical wall thereof to discharge a cleaning liquid into the impeller. <IMAGE>
