Abstract
Abstract A contactor for liquids with gases, solids or liquids which can also serve as an entrainment separator for separating liquids from gases and solids from gases, includes a housing providing an inlet at one end and an outlet at the opposed end, means to introduce a mist or spray of liquid and positioned between said inlet and an adjustable surface (preferably planar) providing a face facing the inlet and the means for introducing said liquid, and an opposed face, an annular deflector beneath the planar surface attached to the housing and extending inward of the housing and positioned relative to the planar surface to provide an opening between the planar surface and annular deflector, means to adjust the position of the planar surface relative to the annular deflector, a tube attached to the opposed face of the planar surface and extending downward of the inlet, a funnel providing a downward extending spout positioned below the tube, means providing flow of liquid in the funnel past the tube and to the spout, and a gas outlet extending through the side of the housing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
260 words
A combination liquid-gas contactor and entrainment separator comprising: a. a housing having inlet means for introducing a flow of gas into said housing, first outlet means for withdrawing liquids and solids, separated from said gas, from said housing, and second outlet means for withdrawing gas, substantially free of entrained liquids and solids, from said housing, said inlet means and said first outlet means being disposed in opposite ends of said housing, said second outlet means being disposed in said housing intermediate said inlet and first outlet means; b. spray means for injecting a liquid mist into said housing, said spray means being configured and positioned for contacting said liquid mist with the gas introduced into the housing; c. a member having means defining a first surface for intercepting both the flow of gas introduced by the inlet means and the liquid mist injected by the spray means, and a second surface opposite said first surface; d. a tube disposed within said housing and extending away from said second surface; e. annular deflector means disposed adjacent to the member, attached to the housing and extending inward of the housing and positioned relative to the member to provide an opening therebetween; the deflector means being operative for directing the gas flow toward said tube; f. means for adjusting the position of the member relative to the annular deflector means, thereby varying the size of said opening; and, g. funnel means at least partly surrounding said tube for conducting flow of liquids and solids separated from the gas into said second outlet means.
Claim 2
Dependent Claim
260 words
A combination liquid-gas contactor and entrainment separator comprising: a. a housing having inlet means for introducing a flow of gas into said housing, first outlet means for withdrawing liquids and solids, separated from said gas, from said housing, and second outlet means for withdrawing gas, substantially free of entrained liquids and solids, from said housing, said inlet means and said first outlet means being disposed in opposite ends of said housing, said second outlet means being disposed in said housing intermediate said inlet and first outlet means; b. spray means for injecting a liquid mist into said housing, said spray means being configured and positioned for contacting said liquid mist with the gas introduced into the housing; c. a member having means defining a first surface for intercepting both the flow of gas introduced by the inlet means and the liquid mist injected by the spray means, and a second surface opposite said first surface; d. a tube disposed within said housing and extending away from said second surface; e. annular deflector means disposed adjacent to the member, attached to the housing and extending inward of the housing and positioned relative to the member to provide an opening therebetween; the deflector means being operative for directing the gas flow toward said tube; f. means for adjusting the position of the member relative to the annular deflector means, thereby varying the size of said opening; and, g. funnel means at least partly surrounding said tube for conducting flow of liquids and solids separated from the gas into said second outlet means.
Claim 3
Dependent Claim
19 words
The combination contactor-separator of claim 1 wherein the housing includes a removable cover with the inlet means disposed therein.
Claim 4
Dependent Claim
17 words
The combination contactor-separator of claim 1 further including means for securing the funnel means to the tube.
Claim 5
Dependent Claim
43 words
The combination contactor-separator of claim 3 wherein the means for securing the funnel means to the tube is further operative for regulating flow of the gas between said tube and funnel means by adjusting a spacing between the tube and the funnel means.
Claim 6
Dependent Claim
15 words
The combination contactor-separator of claim 1 wherein the funnel means is secured to the housing.
Claim 7
Dependent Claim
46 words
The combination contactor-separator of claim 1 wherein the funnel means includes a spout having a lateral gas port therein and said combination contactor-separator further comprises shield means, attached to the funnel, for preventing liquids or solids, separated from said gas, from flowing through the gas port.
Claim 8
Dependent Claim
41 words
The combination contactor-separator of claim 1 wherein the annular deflector means is attached to the housing and extends inwardly and downwardly of the housing at an angle of about 15° to about 75° relative to a longitudinal axis of said housing.
Claim 9
Dependent Claim
41 words
The combination contactor-separator of claim 1 wherein the annular deflector means is attached to the housing and extends inwardly and downwardly of the housing at an angle of about 30° to about 60° relative to a longitudinal axis of said housing.
Claim 10
Dependent Claim
23 words
The combination contactor-separator of claim 1 wherein the second outlet means includes a pipe extending through a housing sidewall and into the housing.
Claim 11
Dependent Claim
21 words
The combination contactor-separator of claim 1 further comprising means for washing collected liquids and solids from interior portions of the housing.
Claim 12
Dependent Claim
44 words
The combination contactor and entrainment separator of claim 1 wherein the spray means is further configured and disposed within said housing for injecting a liquid mist in a direction generally countercurrent to the direction of the flow of gas introduced by said inlet means.
Claim 13
Dependent Claim
44 words
The combination contactor and entrainment separator of claim 1 wherein the spray means is further configured and disposed within said housing for injecting a liquid mist in a direction generally co-current with the direction of the flow of gas introduced by said inlet means.
