Horizontal venturi scrubber

Apparatus comprising a horizontally disposed scrubber vessel, said vessel having an inlet at one end and an outlet at an opposite end, a horizontally disposed wall in said vessel, a liquid tank below said wall in said vessel, said wall supporting at least one upright moisture eliminator above said wall and through which a horizontally disposed gas stream above said wall must pass when flowing from said inlet to said outlet, a venturi housing having its outlet connected to said vessel inlet, said venturi inlet and outlet being at approximately the same elevation so that flow through said venturi housing is generally horizontal, an anvil, a movable member in said housing and cooperating with said anvil to define a venturi throat, said member being pivotably supported by said housing for movement about a horizontally disposed axis transverse of said housing, an actuator externally of said housing and connected to said member for moving said member to adjust the area of the venturi throat defined by the space between said anvil and said member, means defining a horizontally disposed water inlet slot in said venturi housing upstream from and adjacent to said member, said venturi housing having a chamber for feeding a liquid to said slot, a pump connected to said chamber and to said tank for pumping an aqueous liquid from said tank to said chamber, and said vessel having a chamber upstream of said wall and below the elevation of said moisture eliminator for collecting liquid introduced into said venturi housing through said slot and which enters said vessel through said vessel inlet.
