Abstract An apparatus and method for scrubbing gases with liquid. The apparatus employs a plurality of nozzles which discharge several streams of the gas downwardly against the surface of the scrubbing liquid (e.g., water). Each nozzle has a shield which overlies the liquid body and confines the movement of gas and entrained liquid from the region of impingement with the liquid. The nozzles and their shields are arranged in a cluster within a reservoir. In carrying out the method, the gas flow is discharged from the several nozzles and caused to impinge on the surface of the liquid, the flow velocity being such that depressions are formed in the liquid body immediately below the nozzles. Some initial scrubbing action is effected by such impingement, and the impingement causes some of the liquid to be entrained in the gas flow whereby a gas-liquid mixture flows outwardly in a radial direction from the region of each depression and through the spaces underlying the shields. Also, the gas-liquid mixture discharging from the region of each depression is caused to intermingle with the gas-liquid mixture discharging in an opposite direction from at least one adjacent nozzle, thereby causing further turbulence and scrubbing action. This invention relates generally to an apparatus and method for subjecting air and other gases to scrubbing with water or other liquid.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
39 words
A method as in claim 1 in which the mixture of gas and liquid discharging from each of said streams is caused to commingle with turbulence with the gas and entrained liquid discharging from at least one adjacent stream.
Claim 2
Dependent Claim
162 words
In gas scrubbing apparatus, a reservoir adapted to contain a body of scrubbing liquid, a plurality of gas nozzles disposed within the reservoir above the surface of the liquid body, said nozzles being disposed to discharge gas downwardly upon the surface of the liquid body in spaced regions, manifold means for delivering flow of gas to be scrubbed into said nozzles, and a generally horizontal shield mounted upon each of the nozzles adjacent the lower discharge end of the same, discharge of gas from said nozzles being caused to impinge upon the surface of the liquid and to depress the liquid surface in regions immediately underlying the nozzles, each of said shield means serving to provide a confined annular space between the same and the surface of the liquid, whereby gas after impingement with the liquid body flows outwardly with entrained liquid in directions through the confined annular space transverse to the gas discharge to promote scrubbing action between gas and liquid.
Claim 3
Dependent Claim
39 words
Apparatus as in claim 3 in which the shield for each of said nozzles is circular in plan, the shields of adjacent nozzles being spaced apart by a distance which is substantially less than the radius of each shield.
Claim 4
Dependent Claim
20 words
Apparatus as in claim 4 in which said nozzles and associated shields are arranged as a cluster within the reservoir.
