Scrubber for cleaning of a gas

A scrubber for cleaning of a gas, comprising

• a casing extending along a longitudinal central axis (x) and enclosing a scrubbing chamber, wherein the casing has a gas inlet for the gas to be cleaned, which extends into the scrubbing chamber, and a gas outlet for the cleaned gas, which extends out from the scrubbing chamber, wherein the casing is configured to permit a gas flow of the gas to flow through the scrubbing chamber in a flow direction from the gas inlet to the gas outlet,
• a deflector device provided in the scrubbing chamber between the gas inlet and the gas outlet and forming a gas passage between the deflector device and the casing, which deflector device comprises an upstream surface facing the gas inlet, and
• a spraying nozzle configured to spray a scrubbing liquid into the scrubbing chamber and the gas flow,
• a separation device, which comprises a shield element arranged between the upstream surface of the deflector device and the gas inlet and at least partly shielding the upstream surface from the gas flow, which shield element is perforated by a plurality of holes, wherein the shield element is arranged so as to provide a collecting gap between the upstream surface and the shield element, and the holes extend through the shield element from the scrubbing chamber to the collecting gap to permit scrubbing liquid to enter the collecting gap, and wherein the separation device comprises a drain outlet configured to drain scrubbing liquid from the collecting gap.
