Second means is provided for varying the thickness of said foam layer across said housing, thereby obtaining a substantially uniform gas velocity through the foam layer throughout the flow cross section of the foam bed.,下面是Gas scrubber专利的具体信息内容。

1. A wet-type gas scrubber comprising a housing having an inlet for contaminated gas and an outlet for cleansed gas spaced above said inlet, means for wetting said gas with scrubbing liquid, filter means extending transversely between said inlet and outlet for accelerating said wetted gas to high velocity and forming a layer of liquid foam bubbles across said housing between said inlet and outlet, and filter support means for supporting said filter means and means for tilting said filter means to a plurality of adjustable tilt positions relative to the horizontal forming a nonuniform thickness of said foam layer across said housing and means for maintaining said support means in a selected one of said positions.
2. The scrubber of claim 1 wherein said filter means comprises a filter bed including a grid across said housing and a plurality of separate, movable filter elements several layers deep mounted on said grid and said filter support means includes adjustable support means for supporting said grid in a position tilted relative to the horizontal whereby a nonuniform depth of foam layer is obtained across said plate.
3. The scrubber of claim 1 wherein said filter means comprises a perforated plate having a plurality of apertures therein and said filter support means includes adjustable support means for supporting said plate in a position tilted relative to the horizontal whereby a nonuniform depth of foam layer is obtained across said plate.
4. The scrubber of claim 3 including flexible seal means around the periphery of said plate sealingly secured to the inside surface of said housing.
5. The scrubber of claim 4 including drain means above the level of said perforated plate for limiting the upper level of said foam layer by removal of contaminated liquid.
6. A gas scrubber comprising a housing having an inlet for contaminated gas adjacent the lower end and an outlet for cleansed gas adjacent the upper end, a filter bed across said housing intermediate said inlet and outlet including a supporting grid and frame and a plurality of separate individually discrete, filter elements on said grid relatively movable over said grid stacked several layers deep, and adjustable filter bed support means for supporting said filter bed in said housing, means for tilting said filter bed to a plurality of adjustable tilt positions relative to the horizontal and means for maintaining said support means in a selected one of said positions, said elements movable across said tilted grid toward lower portions thereof forming a nonuniform depth of elements in different portions of said filter bed.
7. The gas scrubber of claim 6 wherein said adjustable support means includes a trio of vertically adjustable support members mounted at spaced locations around the inside of said housing.
8. The gas scrubber of claim 7 wherein said housing includes a cylindrical wall section and said inlet is formed on one side of said wall section and wherein said support means includes a cylindrical ring and a plurality of spaced-apart, vertical ribs across said ring for supporting said grid.
9. The gas scrubber of claim 8 including drain means adjacent the center of said grid for removing liquid from said filter bed and discharging the same into the lower end of said housing and valve means operable to open and close said drain means in response to the head of liquid collected therein.
10. The gas scrubber of claim 8 wherein said trio of adjustable support members are in engagement against said vertical support ribs.
11. The gas scrubber of claim 8 wherein said cylindrical ring extends upwardly above said grid for containing said filter elements around the edge of said filter bed.
