Abstract

A process and apparatus for the removal of particulate matter and reactive or water soluble gases from carrier gases is disclosed. The process includes driving the carrier gas through a conduit, in part by a fan or blower, passing the carrier gas through a turbulent free jet emitted from a supersonic nozzle and containing a large number of small high velocity liquid droplets, passing the mixture of the carrier gas and the free jet through a subsonic nozzle, injecting additional liquid as droplets into the mixture, retaining the mixture in a mixing tube to promote the further growth of the liquid droplets and separating the liquid droplets from the carrier gas. The apparatus includes a conduit having mounted therein a supersonic nozzle and liquid injector apparatus located upstream from a subsonic and liquid injector nozzle, a mixing tube downstream from the subsonic nozzle, separating means downstream from the mixing tube and blower or fan means arranged to drive, at least in part, the carrier gas containing pollutant material through the apparatus.
