Abstract
Abstract A single-stage or plural-stage scrubber having a cylindrical or polyhedral housing is provided with a bottom partitioning the housing into upper and lower portions and provided with an outlet of a cross-section less than that of the partitioned housing through which the gas emerges. Below this bottom is provided an upward open tub and a ring is provided between the outlet and the tube to define a laterally open clearance which is adjustable by vertical displacement of the ring. Preferably two such rings are used in telescoping relationship and one of the rings is vertically displaceable, the ring defining a variable lateral cross-section designed for linear pressure characteristics with axial displacement of one of the rings.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
An apparatus for the scrubbing of a gas with a liquid, comprising an upright housing formed with an inlet at an upper portion and an outlet at a lower portion; a partition in said housing subdividing same between said portions into a pair of chambers, said partition being formed with a generally central opening traversable by gas and interconnecting said chambers; a tub fixed in said housing below said opening, said tub being aligned with and concave toward said opening but spaced axially from said partition; a first annular member disposed in said opening and a movable second annular member received in said tub, said annular members defining a lateral gap traversable by a liquid/gas mixture; means connected to said second member for relatively displacing said members to vary said gap; and spray means above said opening for directing liquid toward said opening.
Claim 2
Independent Claim
143 words
An apparatus for the scrubbing of a gas with a liquid, comprising an upright housing formed with an inlet at an upper portion and an outlet at a lower portion; a partition in said housing subdividing same between said portions into a pair of chambers, said partition being formed with a generally central opening traversable by gas and interconnecting said chambers; a tub fixed in said housing below said opening, said tub being aligned with and concave toward said opening but spaced axially from said partition; a first annular member disposed in said opening and a movable second annular member received in said tub, said annular members defining a lateral gap traversable by a liquid/gas mixture; means connected to said second member for relatively displacing said members to vary said gap; and spray means above said opening for directing liquid toward said opening.
Claim 3
Dependent Claim
49 words
The apparatus defined in claim 1 wherein at least one of said members is formed with a crenellated edge turned toward the other of said members imparting to said gap an approximately linear characteristic between the pressure drop across said gap and the relative axial positions of said members.
Claim 4
Dependent Claim
45 words
The apparatus defined in claim 1 wherein said second member is formed wtih a felly coaxial with said tub, a hub within said felly and spokes connecting said felly with said hub, said means for relatively displacing said members including a rod engaging said hub.
Claim 5
Dependent Claim
28 words
The apparatus defined in claim 1, fUrther comprising an upstanding duct fixed to said partition and surrounding said opening for defining an annular liquid-collection chamber around said duct.
Claim 6
Dependent Claim
43 words
The apparatus defined in claim 1, further comprising a hood connected to the rim of said tub and convex in the direction of said partition, said hood reaching outwardly away from said partition toward the housing wall and defining an annular space therewith.
Claim 7
Dependent Claim
17 words
The apparatus defined in claim 5, further comprising droplet-separation baffles angularly spaced apart in said annular space.
Claim 8
Dependent Claim
99 words
The apparatus defined in claim 1 wherein said partition is generally horizontal and is upwardly concave, said apparatus further comprising a downwardly directed nozzle axially aligned with and spaced away from said opening for directing a conical spray of liquid therethrough; an upstanding duct coaxial with said opening and surrounding same above said partition and anchored thereto for defining a liquid collection chamber around said duct; an upwardly convex apron below said partition anchored to said rim of said tub and extending inwardly toward the wall of said housing; and a liquid-collection sump below said hood in said housing.
Claim 9
Dependent Claim
39 words
The apparatus defined in claim 7 wherein one of said members is crenellated along its edge facing the other of said members to maintain the pressure drop across said gap substantially in a linear function with the gap spacing.
Claim 10
Dependent Claim
32 words
The apparatus defined in claim 8, further comprising baffles angularly spaced about said hood and received in said annular space for separating droplets of liquid from the gas traversing said annular space.
