1. A gas scrubber comprising an enclosed vessel having a bottom, top and side walls, means dividing said vessel into upper and lower compartments, dirty gas inlet means in said upper compartment, clean gas outlet means in said lower compartment, at least one substantially vertically disposed open-ended gas collecting tube mounted in said dividing means and extending into at least one of said compartments, the inside of each said gas collecting tube being substantially completely open throughout its length, the bottom portion of said lower compartment below the bottom end of each said gas collecting tube defining a settling basin, at least one atomizing nozzle, means for circulating scrubbing liquid from said settling basin to each atomizing nozzle, and means for supplying compressed gas to each atomizing nozzle for atomizing the scrubBing liquid and accelerating it to a high velocity, each atomizing nozzle being positioned in said lower compartment below a gas collecting tube for discharging a mixture of atomized scrubbing liquid and compressed gas upwardly into said gas collecting tube countercurrent to the flow of dirty gas whereby high energy contact is achieved between the dirty gas and the atomized scrubbing liquid.
2. The gas scrubber according to claim 1 further comprising means for maintaining a substantially constant level of scrubbing liquid in said settling basin.
3. The gas scrubber according to claim 2 wherein the bottom of said vessel is sloped and contains, at about its lowest point, means for removal of sludge from said settling basin.
4. The gas scrubber according to claim 2 including scrubbing liquid return means connecting said upper compartment with the scrubbing liquid in said settling basin for return of scrubbing liquid from said upper compartment to said settling basin.
5. The gas scrubber according to claim 2 wherein the discharge orifice of the atomizing nozzle is above the surface of the scrubbing liquid in the settling basin and the nozzle comprises a hollow tube having a discharge orifice and said means for supplying compressed gas to said atomizing nozzle includes means, in said hollow tube for delivering a compressed gas to a point below said discharge orifice.
6. The gas scrubber according to claim 2 wherein the discharge orifice of the atomizing nozzle is above the surface of the scrubbing liquid in the settling basin and the nozzle comprises a hollow tube having a flared discharge orifice, a restricted throat downstream from said orifice, and means in said hollow tube for delivering compressed gas to a point below said restricted throat.
7. The gas scrubber according to claim 6 including at least one open-ended conduit affixed to said dividing means and extending downwardly therefrom to a point below the surface of the scrubbing liquid in said settling basin and sludge removal means in the bottom of the settling basin.
8. A gas scrubber comprising a series of scrubbers according to claim 2 wherein the dirty gas inlet means for each individual scrubber is in fluid flow communication with means connected to the source of dirty gas and the clean gas outlet means for each individual scrubber is in fluid flow communication with a common exhaust means.
9. A gas scrubber comprising an enclosed vessel having bottom, top and side walls, means dividing said vessel into first and second compartments, dirty gas inlet means in said first compartment, at least one open-ended gas collecting tube mounted in said dividing means and extending into at least one of said compartments, the inside of said gas collecting tube being substantially completely open throughout its length, the lower portion of said second compartment below one end of said gas collecting tube defining a settling basin, an atomizing nozzle positioned so as to discharge a scrubbing liquid upwardly into each said collecting tube countercurrent to the flow of dirty gas whereby high energy contact is achieved between the dirty gas and the scrubbing liquid, and means for circulating scrubbing liquid from said settling basin to said atomizing nozzle.
10. The gas scrubber according to claim 9 wherein said atomizing nozzle comprises a hollow tube having a discharge orifice and means in said hollow tube for delivering a compressed gas to a point below said discharge orifice whereby a mixture of scrubbing liquid and compressed gas is discharged into each said gas collecting tube.
11. A gas scrubber comprising a vessel having a bottom, top and side walls, means dividing said vessel into first and second compartments, dirty gas inlet means in said first compartment, clean gas outlet means in said second compartment, at least one open-ended gas collecting tube mounted in said dividing means; the lower portion of said second compartment below said gas collecting tube defining a settling basin, an atomizIng nozzle, and means for supplying a compressed gas to said atomizing nozzle for atomizing the scrubbing liquid and accelerating the atomized scrubbing liquid to a high velocity; said atomizing nozzle being positioned for discharging a mixture of compressed gas and scrubbing liquid into each gas collecting tube countercurrent to the flow of dirty gas whereby high energy contact is achieved between the dirty gas and the atomized scrubbing liquid.
12. A gas scrubber comprising a vessel, at least one gas collecting tube mounted in and having an open end communicating with said vessel; said gas collecting tube being substantially completely open throughout its length; dirty gas inlet means communicating with said tube; clean gas outlet means communicating with said vessel and separated from direct communication with the dirty gas inlet means; said vessel defining a settling basin below said tube; an atomizing nozzle; means for supplying a scrubbing liquid to said atomizing nozzle; and means for supplying a compressed gas to said atomizing nozzle for atomizing the scrubbing liquid and accelerating the atomized scrubbing liquid to a high velocity; said atomizing nozzle being positioned for discharging a mixture of compressed gas and atomized scrubbing liquid into the gas collecting tube countercurrent to the flow of dirty gas whereby high energy contact is achieved between the dirty gas and the atomized scrubbing liquid.
