SCRUBBER FOR CLEANING THE EXHAUST GASES OF A DIESEL ENGINE, METHOD OF OPERATING IT AND CORRESPONDING MARITIME VEHICLE

摘要

The scrubber comprises several gas inlet tubes (8) having an upstream end (8’’) able to be fed from the gas inlet (4) and a downstream end (8’) opening into the scrubbing volume (16), means (10, 12) for spraying scrubbing liquid near the upstream end (8’’) of the inlet tubes (8) and means (26) for removing the scrubbed gases from the chamber. Each inlet tube (8), which in particular is of the Venturi type, is able to confer upon the gas that is to be scrubbed a pressure that is markedly higher, at the downstream end (8’) of the tube, than the pressure of the gas at the upstream end (8’’) of the tube (8), and the downstream end (8’) of each tube (8) in service extends below the free surface (S) of the scrubbing liquid (L).
