The invention discloses a hypochlorous acid electrolysis system based on a grading method and a control method thereof. The system comprises a plurality of electrolysis units and a controller, the electrolysis units are connected in series through water conveying pipes, an electric control valve is installed on each water conveying pipe, the electric control valves are electrically connected withthe controller, and water outlet branch pipes are installed on pipelines of the water conveying pipes between the electric control valves and the electrolysis units. The water inlet of the electrolysis unit at the head end is connected with a seawater pipeline, and the water outlet of the electrolysis unit at the tail end is connected with a main water outlet pipe. The concentration of a sodium hypochlorite solution generated by the system is adjusted by adopting the grading method, so that the requirement of daily inactivation is met, a marine organism preventing device does not need to be mounted on a ship, and the treatment efficiency of marine organisms in a water ballast tank, a sea chest and a seawater header pipe is greatly improved.
Description
technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a hypochlorous acid electrolysis system based on a classification method and a control method thereof. Background technique [0002] When the ship is empty, in order to keep the ship at a certain draft without capsizing, ballast water will be added to the ballast tank. There are a lot of organisms in the water, including plankton, microorganisms, bacteria and even small fishes, as well as eggs, larvae or spores of various species. These organisms will be added to the ballast tank along with the seawater. During the voyage of the ship, some Organisms die because they cannot adapt to changes in temperature, salinity and other factors, but some can survive. The ballast water in the ballast tank is discharged to the destination sea area until the end of the voyage. [0003] In order to prevent the alien marine organisms in the ballast water from causing harm to the marine ecol...
