Mechanism for treating exhaust gas of an internal combustion piston engine of a marine vessel and method of operating a mechanism for treating exhaust gas

摘要

The mechanism for treating the exhaust gas of the internal combustion piston engine (4) of the marine vessel (1) has a first end (12.1) connected to the engine (4) and a second end (12. 2) a scrubber unit (2) disposed between the exhaust gas flow path (12) that opens to the surrounding environment, and the first end (12.1) and the second end (12.2). 14), and the mechanism includes a cleaning liquid on an inner surface (10) of the exhaust gas flow path in a portion of the exhaust gas flow path between the scrubber unit and the second end of the exhaust gas flow path. An exhaust gas flow path cleaning system (16) arranged to apply The invention also relates to a method of operating the mechanism in two modes. The exhaust gas is processed by the scrubber unit while the engine is running, and the cleaning liquid is applied while the engine is stopped.
