Abstract: An exhaust gas cleaning system includes a particle filter device comprising a casing, plural hollow ceramic filter rods arranged at least partly inside a gas passage of the casing, and a gas inlet and gas outlet. The particle filter device guides exhaust gas from the gas inlet, through the gas passage and to the gas outlet. The particle filter device further comprises a perforated plate extending at least partly along the filter rods and partly blocking an exhaust gas flow path from the gas inlet to the gas passage. The perforated plate defines openings allowing exhaust gas to flow into the gas passage. The filter rods are gas permeable to allow exhaust gas to penetrate, during filtration, a respective wall of the filter rods and flow into the filter rods. A respective open upper end of the filter rods communicates with the gas outlet so exhaust gas leaves the casing.

Abstract: An exhaust gas cleaning system (1, 49, 77, 107), a method and a use are provided. The exhaust gas cleaning system is for cleaning exhaust gas (EG) onboard a ship and comprises an exhaust gas inlet (5, 79) for receiving the exhaust gas to be cleaned, and a scrubber (9, 51, 83) arranged to clean, in a scrubbing section (11, 53, 89) of the scrubber, the exhaust gas from pollutants. The scrubbing section comprises an exhaust gas inlet (19) for receiving the exhaust gas and an exhaust gas outlet (15, 57) for outputting the exhaust gas. The exhaust gas cleaning system further comprises a wet Electrostatic Precipitator (39) arranged to further clean the exhaust gas from pollutants after it has been cleaned in the scrubbing section.

Abstract: A scrubber for cleaning of a gas comprises a casing, enclosing a scrubbing chamber. The casing comprises a gas inlet into and a gas outlet out from the scrubbing chamber. The casing permits the gas to flow through the scrubbing chamber from the gas inlet to the gas outlet. A deflector device is provided in the scrubbing chamber between the gas inlet and the gas outlet and forms a passage between the deflector device and the casing. The deflector device comprises a downstream surface facing the gas outlet and having an outer edge. A spraying nozzle is configured to spray a scrubbing liquid into the scrubbing chamber and the gas flow. A channel member extends from the deflector device. The channel member leads scrubbing liquid collected by the deflector device from the deflector device.

Abstract: A scrubber for cleaning a gas comprises a casing extending along a longitudinal central axis and enclosing a scrubbing chamber. The casing has a gas inlet and a gas outlet. The casing is configured to permit flow of the gas through the scrubbing chamber in a flow direction from the gas inlet to the gas outlet. A deflector device in the scrubbing chamber between the gas inlet and outlet forms a gas passage between the deflector device and the casing. The deflector device comprises an upstream surface facing the gas inlet. A spraying nozzle is configured to spray a scrubbing liquid into the scrubbing chamber and the gas flow. A separation device comprises a shield element and is arranged between the upstream surface of the deflector device and the gas inlet. The shield element shields the upstream surface from the gas flow and is perforated by a plurality of holes.

Abstract: A scrubber for cleaning of a gas comprises a casing enclosing a scrubbing chamber. The casing comprises a gas inlet into and a gas outlet out from the scrubbing chamber. A gas flow of the gas flows through the scrubbing chamber in a flow direction from the gas inlet to the gas outlet. A deflector device is provided in the scrubbing chamber between the gas inlet and the gas outlet and forms a passage between the deflector device and the casing. A spraying nozzle is arranged between the gas outlet and the deflector device for spraying a scrubbing liquid into the scrubbing chamber and the gas flow. An inner shield extends between the casing and the deflector device, surrounds the deflector device at least partly, and forms a gap with the casing. Scrubbing liquid may flow through the gap.
