Abstract
Abstract This disclosure teaches a Venturi type scrubber of rectangular cross section and having water jets staggered in a row in opposed wide side walls thereof. Each of the nozzles is provided with a tubular diaphragm to control flow therethrough. The nozzles of each side wall are connected to a water box which in turn communicates with a water feed line via a valve.
