Description
Technical field
The present invention relates to water screw anti-soil technology field, more particularly, relate to a kind of propeller shore-based electrolytic seawater antifouling system and method.
Background technology
Along with the development of shipbuilding industry and ocean exploitation cause, sea marine organism pollution has caused people's common concern to the serious harm that boats and ships, naval vessels, offshore drilling platform and harbour etc. bring.Because marine life adheres to the resistance that has increased boats and ships on shell and water screw, reduced route speed, has increased the consumption of fuel, and has quickened the corrosion of shell.Marine life adheres to the service discharge that can reduce water coolant significantly in Sea Chest, condenser piping, make main frame normally not move, and severe patient will be forced to stop transport.Therefore increased operation and maintenance cost or caused great financial loss.Marine life at sea adheres in the salt water cooling system of oil platform, power house, strand and chemical industry equipment too can cramming, makes that to rotate office malfunctioning, and gate can't be closed, unlatching etc.Utilize seawater resources so solve the problem of sea marine organism pollution for us, the exploitation ocean has vital role.
The method that prevents sea marine organism pollution is a lot, for example application anti-fouling material, chlorination, electronics antifouling, manually root out or the like.The application anti-fouling material is the method that generally adopts at present, and the hull plate that is easy to brush construction etc. has been used widely, exists difficulty on the construction technology with the pipeline privileged sites.When chlorination is antifouling, must take safety measures to the storage of chlorine and transportation.Manually rooting out to stop work carries out, and this is a kind of forced method.
For the anti-soil technology of water screw, early stage for the copper alloy water screw that does not apply galvanic protection, utilize its copper alloy matrix material self to discharge cupric ion and kill marine life and can reach anti-fouling effect.But along with development of technology, cathode protection technology is applied to water screw anticorrosion gradually, and this technology also makes water screw lose the antifouling effect of self when the protection water screw exempts from sea-water corrosion; At present external antifouling mainly being still of water screw utilized metal antifouling coating and nonmetal antifouling coating, or the two is combined protects water screw simultaneously, and antifouling principle is similar to shell, does not still still have effective anti-pollution measure at present.Because the problem of propeller for vessels sea marine organism pollution is more serious, directly can have influence on the speed of a ship or plane and the noise of boats and ships, this becomes the difficult problem that present urgent need solves.
