Problems solved by technology

However, after the IMO Ballast Water Convention came into effect, ballast water treatment devices must be installed on large ocean-going ships to meet the new environmental protection requirements, which overlaps with the anti-sea organisms device of the original cooling water system on board the ship, making shipbuilding greatly increased cost

Abstract

The invention discloses a system for treating cabin seawater pipe microorganisms by a ballast water device and a ship, the system comprises the ballast water treatment device, a sea chest, a ballast tank, cabin equipment and a control box, the ballast water treatment device comprises two groups of electrolysis mechanisms which operate in parallel, and the electrolysis mechanisms are respectively afirst electrolysis mechanism and a second electrolysis mechanism; the first electrolysis mechanism is connected with a water outlet pipeline through a first water conveying pipe, and the water outletpipeline is connected with the sea chest; the second electrolysis mechanism is connected with a second water conveying pipe and the ballast tank, the second water conveying pipe is communicated witha switching valve, and the ballast tank and the cabin equipment are both connected with a seawater header pipe on the sea chest. By reasonably arranging the pipelines in the system, a sodium hypochlorite solution generated by electrolysis of the ballast water treatment device can treat the microorganisms in the ballast tank and a cabin seawater pipe at the same time, a cabin marine organism prevention device does not need to be installed on the ship, and the shipbuilding cost is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a system for treating microorganisms in engine room seawater pipes by a ballast water device and a ship. Background technique [0002] The methods of killing marine microorganisms in the ballast water treatment device of marine equipment include ultraviolet disinfection, chemical disinfection, and hypochlorous acid disinfection. The anti-marine biological device in the engine room has electrolytic copper and aluminum rods and hypochlorous acid disinfection methods to kill marine microorganisms. However, after the IMO Ballast Water Convention came into effect, ballast water treatment devices must be installed on large ocean-going ships to meet the new environmental protection requirements, which overlaps with the anti-sea organisms device of the original cooling water system on board the ship, making shipbuilding The cost is greatly increased. Therefore, how to make the bal...
