Scrubbing dust collector and exhaust gas treatment installation

摘要

An improved scrubbing dust collector and exhaust gas treatment installation are described. The collector (2) includes a tank (21) containing a washing liquid, a scrubbing tower (22) on the upper portion of the tank into which an exhaust gas is introduced, a jetting nozzle (25) on the upper portion of the tower, and at least one netting member (42) located in a lower portion of the tower. The netting may be installed in a frame (40) which has slits therein. A plurality of netting members may be employed and a lower member may have a smaller mesh size than an upper one. The installation includes the scrubbing dust collector (2), a combustor (1) and a separator tower (23). As washing liquid is jetted from the nozzle (25), it passes downward in the scrubbing tower and forms a membrane-like layer on the netting member thereby providing a larger contact area between the exhaust gas and the washing liquid.
