1. A wet scrubber useful for cleaning a process gas, the wet scrubber comprising:
at least a first spray level system supplied an absorption liquid for atomization by nozzles comprised in the first spray level system, a second spray level system arranged vertically above the first spray level system supplied an absorption liquid for atomization by nozzles comprised in the second spray level system, and a wet scrubber tower housing the first and second spray level systems comprising a process gas inlet located at a base portion of the tower, and a process gas outlet located at an upper portion of the tower, wherein the first spray level system comprises at least one gas-liquid contacting plate located vertically above at least one nozzle of the first spray level system, the at least one gas-liquid contacting plate operative for deflecting absorption liquid atomized by nozzles of the second spray level system flowing downward in the wet scrubber tower to contact process gas already contacted by absorption liquid atomized by the at least one nozzle of the first spray level system, and at least one adjustable damper located adjacent to the at least one gas-liquid contacting plate for controlling vertical velocity of process gas contacted by deflected absorption liquid. |
