Apparatus for gas scrubbing and particulate solids removal

A scrubber unit for removing solid particulates and contaminants from air and gas, comprising:

• a. a settling and clarifying tank for containing water including a scrubber section and a discharge section, said tank having bottom and side walls and being provided with conveyor means for moving sediment from the scrubber section to the discharge section,
• b. a scrubber unit mounted on and supported by said tank, said scrubber unit including:
• 1. an outer generally vertically disposed cylindrical housing wall defining an outer column, said outer column having an upper end which is enclosed except for an exhaust stack through which cleaned gas and air are exited from said scrubber unit, and a lower end which opens into and forms a part of said tank,
• 2. a central column disposed generally concentrically inside said outer column having a generally cylindrical upper section and a generally inwardly and downwardly tapering frusto-conical section, the upper end of said central column being closed and the lower end being open and terminating a predetermined distance above the water in said tank, said upper section having an offcenter opening for tangential introduction of incoming gases thereto and said column having deflector means in a downwardly spiraling pattern on the inside surface thereof.
• c. support means for said central column extending between the outside of said central column and the inside of said outer column, and
• d. baffle means in said tank beneath said central column and below the water level and angling downwardly in a direction away from the discharge end and terminating above said conveyor.
