Abstract
Abstract A method and apparatus for efficiently scrubbing gases in which gas is discharged into a body of liquid and forced beneath a flat distributor plate disposed well within the liquid. The gas volumetric radial flow rate and liquid head causes a thin, high velocity gas stream to be developed giving a high scrubbing and reaction efficiency.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
33 words
The combination of claim 1 in which said open end is circular and said plate is flat and annular, the combination including adjustable supports for said plate facilitating horizontal alinement of the plate.
Claim 2
Dependent Claim
26 words
The combination of claim 2 in which the diameter of the Plate is at least 3 1/2 times greater than the diameter of said open end.
Claim 3
Dependent Claim
20 words
The combination of claim 1 in which said means permits adjustment of the liquid level above said nozzle open end.
Claim 4
Dependent Claim
19 words
The combination of claim 1 including a baffle plate secured to said nozzle and spaced below said open end.
Claim 5
Dependent Claim
40 words
The combination of claim 1 including a wave arrestor band surrounding said nozzle and extending through the upper surface of the scrubber liquid, and a conveyor at the bottom of said tank for removing settled solid matter from the tank.
Claim 6
Independent Claim
65 words
The method of scrubbing a gas comprising the steps of discharging the gas at a high volumetric rate into a body of scrubber liquid, and forcing the gas beneath a substantially flat horizontal surface prior to releasing the gas for upward bubbling movement from the liquid, the interface between said surface and said liquid being thus separated by a thin, high velocity stream of gas.
Claim 7
Dependent Claim
31 words
The method of claim 7 including the steps of controlling the thickness and velocity of said stream by adjusting said volumetric rate and the head of scrubber liquid above said surface.
