摘要： An exhaust air scrubber for removing dust, abraded product, and water-soluble constituents from process exhaust air may include in a single housing a cleaning stage that includes a droplet separator and a packing disposed below the droplet separator. The exhaust air scrubber may also include an inlet apparatus for process exhaust air disposed in a lower portion of the housing, a withdrawal apparatus for scrubbing solution, and a withdrawal conduit for cleaned exhaust air, with the withdrawal conduit beginning inside the housing above the cleaning stage, passing downward inside the housing, and passing out of the housing to an outside in the lower portion of the housing below the cleaning stage. The scrubber may further include a feed conduit for scrubbing solution in an upper portion of the housing above the cleaning stage.
