Abstract

The electrochemical method of removing biological pollutant of ocean ship is to apply pulse current across the hull as the cathode and the metal titanium or flexible rod or plate as anode separated by, say, 0.3-10 cm to shoot down oyster and other small marine organism attached to the hull. The present invention has the advantages of simple apparatus, simple operation, high efficiency, low power consumption, no environmental pollution, etc.

Description

technical field

[0001] The invention belongs to an electrochemical method for removing biological pollution from ocean ships. Background technique

[0002] Marine ships are immersed in seawater for a long time, and are fouled by the attachment of marine organisms, which brings great harm to the ship. On the one hand, it will increase the weight of the hull and the frictional resistance of the hull, thereby reducing the performance of marine ships and increasing fuel consumption; 1996;1:80). 80% of the friction resistance of marine ships comes from the surface, and the high roughness caused by marine biofouling is the main factor. According to statistics, when marine biofouling is 5%, the resistance is equivalent to twice that of a clean surface, and fuel consumption increases by 10%. In addition, when marine organisms attach to the bottom of the ship, a series of complex physical and chemical changes will occur with the growth of these fouling organisms, which greatly acc...
