专利汇可以提供Gas scrubber专利检索，专利查询，专利分析的服务。并且A gas scrubber comprising a housing having an inlet and an outlet for gas, and a grid structure for introducing contaminant collecting scrubbing liquid into the gas flow. Said grid structure comprises a plurality of V-shaped, liquid troughs in spaced parallel array, having deflector vanes parallel and above the troughs and means for maintaining a relatively constant level of liquid in said troughs for distribution into the high velocity gas flow passing over and between adjacent troughs. Mechanical separator means is provided for removing contaminated scrubbing liquid from the gas after contaminants have agglomerated in the liquid from the gas.，下面是Gas scrubber专利的具体信息内容。
1. Apparatus for scrubbing gas with a liquid for collecting contaminants therefrom comprising vertical flow passage means, a plurality of elongated, liquid holding troughs disposed in spaced apart, parallel, horizontal array across said flow passage means, said troughs having sharp upper edges forming spillways for liQuid flow sucked into said gas flow in the spaces between upper edges of adjacent troughs, said troughs having upper edge wall portions sloping oppositely outwardly from the center of the troughs and dimensioned to provide an unobstructed upper liquid surface area of approximately 60 percent of the total crosssectional area of said flow passage means normal to said vertical gas flow; a second grid structure comprising a plurality of elongated, spaced apart, deflector vanes parallel to said troughs and disposed above the spaces between adjacent pairs of troughs for defining minimum area passageways for said gas as it moves generally through said grid structures; means for supplying liquid to said troughs from supply ends thereof, control means for maintaining a desired level of liquid in said troughs; liquid sump means downstream of said array for collecting contaminated liquid; and separator means downstream of said array for separating liquid droplets from said gas.
2. The gas scrubbing apparatus of claim 1 wherein said separator means comprises an array of sloped vanes arranged in a radial pattern around a common axis for directing said gas in an upwardly spiralling stream outwardly toward a cylindrical surface for collecting liquid droplets therefrom.
3. The gas scrubbing apparatus of claim 1 including an elongated housing section having liquid sump means defined in the lower portion thereof, said liquid troughs being mounted in said housing above said sump means, inlet means for directing gas flow into said housing section downwardly onto said troughs, said separator means including an upright housing in communication with said housing section and laterally offset from said inlet means.
4. The apparatus of claim 1 including a feeder trough disposed at the supply ends of said troughs for supplying liquid to the same, and return means connected between said separator means and said feeder trough for returning separated liquid thereto.
5. The apparatus of claim 4 including make-up supply means connected to a feeder trough adjacent opposite ends of said troughs to provide a supply of liquid to the same.
6. The apparatus of claim 1 wherein said troughs are V-shaped in cross section and have sidewalls arranged at approximately a 45* angle to the general direction of gas flow between adjacent troughs.
7. The apparatus of claim 1 wherein said troughs are spaced to provide a confronting liquid surface to the vertically flowing gas in said passage means of at least one-half of the cross-sectional flow area of said vertical gas flow passage means.
8. Apparatus for scrubbing gas with a liquid for collecting contaminants therefrom comprising a first grid structure having a plurality of elongated, liquid holding troughs disposed in spaced apart, parallel, horizontal array across a vertical flow path of said gas, said troughs having sharp upper edges forming spillways for liquid flow sucked into said gas flow in the spaces between upper edges of adjacent troughs, said troughs having upper edge wall portions sloping oppositely outwardly from the center of the troughs and dimensioned to provide an unobstructed upper liquid surface area of approximately 60 percent of the total cross-sectional area of said flow passage means normal to said vertical gas flow; a second grid structure comprising a plurality of elongated, spaced apart, deflector vanes parallel to said troughs and disposed above the spaces between adjacent pairs of troughs for defining minimum area passageways for said gas as it moves generally vertically through said grid structures; means for feeding liquid to the supply ends of said troughs, control means for maintaining a selected level of liquid in said troughs; liquid sump means downstream of said array for collecting contaminated liquid; and separator means downstream of said array for separating liquid droplets from said gas.
9. The gas scrubber of claim 8 wherein said deflector vanes comprise elongated angles centered bEtween pairs of adjacent liquid troughs.
10. The gas scrubber of claim 8 including a feeder trough connecting supply ends of said troughs for supporting the same and supplying liquid thereto.
11. The gas scrubber of claim 9 wherein said deflector vanes have downwardly sloping flanges with lower edges spaced above upper edges of said liquid troughs to define minimum cross-sectional flow areas therebetween.
12. The gas scrubber of claim 11 wherein each deflector vane defines a pair of minimum cross-sectional flow areas along the lower edges of the flanges thereof, the sum of said flow areas being less than the open space directly between pairs of adjacent liquid troughs.
13. The gas scrubber of claim 12 wherein the area of open space defined between said troughs is less than the surface area of liquid in said troughs.
