Abstract
Liquid effluents are continously discharged into a reaction chamber and vaporized by a flame formed by a jet of gaseous oxidizer which is impelled in rotational motion and into which is introduced a fluid fuel. The ignited oxidizer-fuel mixture is directed into the chamber inlet in a jet which is spatially distinct from the discharge of liquid effluents. The combustible substances contained in the simultaneously atomized liquid effluents are evaporated and burned by the jet of oxidizer-fuel mixture.
Claims15
A method of evaporation and thermal oxidation of liquid effluents in which said effluents are continuously vaporized by a flame, comprising rotating a jet of gaseous oxidizer, introducing a fluid fuel into the jet of oxidizer, igniting and introducing the oxidizer-fuel mixture into a chamber in a rotating outwardly diversing annular jet and introducing a jet of atomized liquid effluent into said chamber with said jet of atomized liquid effluent being concentric to and geometrically distinct in the vicinity of the chamber inlet from the rotating jet of oxidizer-fuel mixture whereby the combustible substances of said liquid effluents are evaporated and burned by the jet of ignited mixture within the chamber.
A device for the evaporation and thermal oxidation of liquid effluents comprising a combustion chamber, a first duct having an atomizer for directing a jet of atomized effluents into a vaporization and combustion chamber, a second duct having means for imparting rotational flow motion to an oxidizing gas within said second duct and a third duct for supplying a fluid fuel and means for directing a jet of fluid fuel from said third duct into the oxidizing gas in said second duct in the vicinity of the chamber inlet so that the ignited fuel-oxidizer mixture will pass into said chamber;
- said chamber inlet having a divergent configuration.
