Abstract
Abstract A gas washing apparatus including an inlet duct with its discharge end submerged in a liquid and having peripheral openings below the level of such liquid but adapted to be exposed by the depression of the liquid level within said duct due to the gas pressure therein. Flared vanes extend outwardly from said openings into the liquid to form a venturi effect. The discharged gases bubble upwardly through the liquid and are passed through a drying apparatus for the removal of entrained liquid droplets.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
Apparatus for washing gases comprising a vessel having a liquid reservoir adapted to contain a wash liquid, a gas inlet duct having its discharge end immersed in the liquid in said reservoir, said duct having a plurality of spaced peripheral openings in its submerged portion, said openings having areas to be exposed due to the depression of the liquid level within said duct due to the gas pressure therein, whereby the gases are discharged outwardly through said openings into the liquid in said reservoir and bubble upwardly therethrough for removing suspended particulate material, outwardly flared vanes disposed by the discharge end of said duct adjacent said openings for forming a vena constricta effect and thus increasing the velocity of the discharged gases, said vanes having openings therethrough for the injection of liquid from the outside of the duct as jets into the gas stream in said vena constricta.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
18 words
Apparatus as set forth in claim 1 in which said vena constricta extends radially outward into said liquid.
Claim 4
Dependent Claim
18 words
Apparatus as set forth in claim 1 in which said vena constricta extends substantially tangentially of said duct.
Claim 5
Dependent Claim
38 words
Apparatus as set forth in claim 1 including a baffle member disposed in said liquid in the path of the rising bubbles on which the bubbles impinge and are deflected before emerging from the surface of said liquid.
Claim 6
Dependent Claim
15 words
Apparatus as set forth in claim 1 in which said openings are triangular in shape.
Claim 7
Dependent Claim
19 words
Apparatus as set forth in claim 5 in which flared vanes extend along the longitudinal sides of said openings.
Claim 8
Dependent Claim
37 words
Apparatus as set forth in claim 1 in which an orifice ring is disposed within said duct at the discharge end thereof below the level of the outside liquid for increasing the gas velocity in said duct.
Claim 9
Dependent Claim
27 words
Apparatus as set forth in claim 7 in which said orifice ring is provided with means for introducing liquid jets into the gas stream in said duct.
Claim 10
Dependent Claim
35 words
Apparatus as set forth in claim 7 in which said ring is provided with an annular passage and with radial passages communicating therewith to discharge jets of liquid into the gas stream in said duct.
Claim 11
Dependent Claim
29 words
Apparatus as set forth in claim 7 in which said duct is provided with openings communicating with said annular passage below the level of the liquid surrounding said duct.
Claim 12
Dependent Claim
27 words
Apparatus as set forth in claim 7 in which means is provided for adjusting the axial position of said ring and securing the same in adjusted position.
Claim 13
Dependent Claim
21 words
Apparatus as set forth in claim 1 including a gas drying zone for removing entrained liquid droplets from the washed gases.
