摘要： The present invention relates to an exhaust system (24) for a combustion engine (30) of a marine vessel (1). The exhaust system (24) includes a flow redirection arrangement (48, 50, 56) in the exhaust gas flow path for restricting a flow of liquid flowing in the reverse flow direction towards the exhaust system inlet. The flow redirection arrangement includes at least one flow redirection feature configured to redirect a first stream of the liquid toward the forward flow direction to collide with a second stream of the flow of liquid. This produces turbulence and dissipates the kinetic energy of the incoming flow of liquid. The invention also relates to motor assemblies and marine vessels having such exhaust systems.

The hub (2) exhibits a central bore (3) arranged to receive a rotating drive shaft (S). Each blade (50, 50') is pivotally fixed to the hub (2) and pivotal about a respective blade pivot axis (P) which extends radially from the hub (2) through the respective blade (50, 50'). Each blade (50, 50') exhibits a leading edge (51, 51'), a trailing edge (52, 52'), a pressure side (54. 54') exhibiting a pressure side area and a suction side (53, 53') exhibiting a suction side area. The blades (50) are mechanically interconnected to freely transfer pivotal movement of each blade to all other blades. The pivotal axis (P) of each blade (50, 50') is positioned such that > 50% of the suction side (53, 53') area and of the pressure side (54, 54') area is arranged between the trailing edge (52, 52') and the pivotal axis (P) of the respective blade (50, 50').

摘要： A wet scrubbing subsystem reduces atmospheric emissions of nitrogen oxides (NO x ) and sulfur oxides (SO x ) from an engine exhaust stream. The exhaust stream is first directed through a catalytic oxidation device that converts NO to NO 2 . In marine applications, the wet scrubbing subsystem can employ seawater scrubbing. The wet scrubbing subsystem can involve a one-stage or multi-stage scrubbing process. The oxidation catalysts in the catalytic oxidation device tend to become poisoned by sulfur species in the exhaust stream. If more than one catalytic oxidation device or catalyst bed is used, one device or bed can be regenerated while another continues to oxidize NO in the exhaust stream. A syngas generator can be employed to produce a syngas stream for use in regenerating the oxidation catalyst. An exhaust stream flow diverter and syngas flow distribution device can be employed to direct the various streams to enable simultaneous catalyst regeneration and exhaust after-treatment.
摘要翻译：湿式擦洗子系统从发动机排气流中减少氮氧化物（NO x x SO）和硫氧化物（SO x x SO）的大气排放。排气流首先通过将NO转化为NO 2的催化氧化装置。在海洋应用中，湿式洗涤子系统可以使用海水洗涤。湿式擦洗子系统可以涉及一级或多级洗涤过程。催化氧化装置中的氧化催化剂倾向于在废气流中被硫物质中毒。如果使用多于一个催化氧化装置或催化剂床，则可以再生一个装置或床，而另一个装置或床可以在排气流中继续氧化NO。可以使用合成气发生器来产生用于再生氧化催化剂的合成气流。排气流分流器和合成气流分配装置可用于引导各种流以实现催化剂再生和废气后处理。
