Gas cleaning system

Claim 1

A gas cleaning system for removing solid particles in a gas having a dirty gas inlet, a clean gas outlet, and means for impelling the gas to be treated from the inlet to the outlet comprising: a cyclone separator communicating with said dirty gas inlet for removing relatively heavy solid particles from the gas being treated; a duct forming a short radius turn of 180* in a vertical plane having one end communicating with the outlet of said cyclone separator for inducing turbulence in the gas flowing therethrough; a first means disposed within the other end of said duct for developing a curtain spray of liquid in an umbrella flow pattern across said duct and directed obliquely counter to the flow of gas therein; a second means developing a curtain spray of liquid in an umbrella flow pattern across said duct and directed obliquely parallel with the flow of gas therein downstream of said first means; a maze of fine stainless steel wire elements which are essentially inert and impervious to the liquid and gasparticle compositions and are randomly disposed in a mass extending across said duct immediately downstream of and below said second means; and a means for collecting the liquid-solid particle residue mixture formed by said system from the gas flow downstream and below said maze, said collecting means comprising a chamber providing an enlarged cross-sectional path for gas flow from said duct; a diffuser directly below said maze and within said chamber having an apex vertically aligned with said maze and downwardly sloping faces extending outwardly from the apex to beyond the vertical projection of said maze; a skirt depending from the outer extremities of said faces; a sump below and spaced from said skirt for reception of the liquid-solid particle residue mixture; and a duct beneath said diffuser and having a port within said skirt for exhausting gas from said collecting means chamber.
