Abstract
Abstract A liquid spray nozzle which includes a pair of concentric tubular members. Liquid to be sprayed is supplied to the outer tubular member and compressed gas is supplied to the inner tubular member. The outer tubular member includes a reducer portion followed by an expander portion. The liquid and gas mix in the reducer portion and the liquid-gas mixture is discharged from the nozzle through the expander portion. The nozzle is particularly designed for use with a gas scrubber and is positioned in the flow path of the gas to be cleaned as it passes from the dirty gas inlet to the clean gas outlet. The liquid spray is countercurrent to the flow of gas to be cleaned.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
236 words
For use in combination with a gas scrubber having an inlet for supplying a gas to be cleaned and an outlet for cleaned gas, a nozzle for spraying scrubbing liquid into the dirty gas in a direction opposite to the flow of gas to be cleaned comprising: a first tubular member; means for supplying scrubbing liquid to said first tubular member; said first tubular member having a portion downstream of said supply means which defines a substantially continuously restricting flow passage; spray director means mounted on said first tubular member and having a flow passage therethrough having a portion downstream of the restricting flow passage of said first tubular member having divergent walls which terminate in an open end; a second tubular member mounted within said first tubular member and defining a flow passage therethrough which terminates within said first tubular member; means for supplying gas at an elevated pressure to said second tubular member whereby the gas mixes with the scrubbing liquid and the mixture is discharged through the open end of said spray director means into the flow of gas to be cleaned in a volume and at a velocity sufficient to clean the gas to be cleaned; and plate means having a plurality of orifices therethrough covering the flow passage through said second tubular member; the longitudinal axes of said orifices being substantially parallel with the longitudinal axis of the first tubular member.

Claim 3
Dependent Claim
45 words
The combination of claim 1 wherein saiD second tubular member is coaxially mounted within said first tubular member and extends into said first tubular member at least as far as said portion of said first tubular member which defines a substantially continuously restricting flow passage.
