Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
52 words
A gas cleaning module according to claim 1 wherein the bottom of said chamber is horizontally inclined in a downward direction to a low point intermediate its horizontal dimension, and means define an outlet from the low point for discharge of dust agglomerated with said first liquid separated from the flue gas.
Claim 2
Dependent Claim
69 words
A gas cleaning module according to claim 1 wherein the collecting means beneath the absorber comprises a first row of horizontally spaced liquid collecting channels extending transversely across the gas flow path, said channels being inclined for liquid discharge at one end thereof, a second row of horizontally spaced liquid collecting channels extending transversely across the gas flow path spaced above said first row and in staggered relationship thereto.
Claim 3
Dependent Claim
20 words
A gas cleaning module according to claim 1 wherein said absorber comprises a series of vertically spaced gas-liquid contact zones.
Claim 4
Dependent Claim
26 words
A gas cleaning module according to claim 4 wherein a demister is positioned above the absorber to remove entrained moisture from the gas leaving the module.
Claim 5
Dependent Claim
33 words
A gas cleaning module according to claim 1 wherein said scrubber includes an accelerating throat with the nozzle means for said first liquid positioned in a converging duct portion opening to the throat.
Claim 6
Dependent Claim
39 words
A gas cleaning module according to claim 6 wherein a downwardly diverging duct opens from said throat and connects with the separating chamber, and the separating chamber is horizontally elongated with the flue gases changing direction in passing therethrough.
