Desulfurization technology of marine engine exhaust gas

摘要

1. Marine engine exhaust desulfurization system to reduce the sulfur oxide in the exhaust of one or more diesel engines of the ship. The system can be configured to operate in an open circuit or closed circuit mode. The system includes a wet scrubber system, at least one available wet scrubber, which can clean the exhaust gas produced by the diesel engine of the ship with the washing liquid, so as to produce a used washing liquid,The wet scrubber includes one or more extraction pipes for extracting the cleaning liquid used before the wet scrubber. The system also includes at least one preparation state reserve, which can be hydrolyzed by magnesium hydroxide of magnesia powder, wherein the preparation state reserve includes a water adding means,The medium in which magnesia powder is added to the powder, and the stirring medium in which water and magnesia powder are mixed together. The system also includes a means for transporting a slurry containing magnesium hydroxide slurry from at least one preparation storage to a place of liquid flow.1. The used washing liquid shall be extracted from one or more pipes to extract the washing liquid, and the magnesium hydroxide slurry shall be connected with the washing liquid used for cleaning and / or the washing liquid used to eliminate its acidity. in additionA method for reducing the amount of sulfur oxide in the exhaust of one or more marine diesel engines.
