Description

Power-free long-life self-driven antifouling device for ship seawater box body environment
Technical Field
The invention belongs to the field of marine organism pollution protection of ships or marine facilities, and particularly relates to a power-free long-life self-driven antifouling device for a ship seawater tank environment.
Background
Under the natural seawater state, the fouling problem caused by the adhesion and growth of marine organisms is very easy to occur in the metal box environments such as ship titanium alloy, steel structures and the like. The ship is usually damaged to cause a plurality of problems of reduced navigation speed, blocked pipeline, induced corrosion, reduced heat exchange efficiency, increased noise and the like. Therefore, it is necessary to combine the target structural materials and environmental factors for use, and to adopt effective measures to prevent marine fouling.
The marine organism pollution protection technology for ships is generally divided into a physical method, a chemical method and a biological method. Wherein, the physical method is physical cleaning or biological adhesion reduction or prevention, and mainly comprises mechanical cleaning, water jet decontamination, ultrasonic wave, ultraviolet ray, low surface energy coating and the like. The chemical method is to utilize specific chemical substances to kill or inhibit the attachment of organisms, and comprises the steps of directly adding medicaments, chemical antifouling paint, electrolytic seawater antifouling, electrolytic copper aluminum antifouling and the like. Biological antifouling is the inhibition of adhesion by certain biological mechanisms, including biological antifouling agents, biomimetic coatings, and the like. The selection of the anti-fouling technology is related to factors such as use conditions, materials, economy, reliability and the like.
However, for the internal box structure of the ship, because the internal operation space is small, mechanical equipment or paint coating workers are difficult to enter, and the construction difficulty is too high, the internal box structure is not suitable for pollution prevention by a physical method and a biological method. In addition, the cost of adding chemical agents is too high for chemical antifouling; the anti-fouling measures for the seawater electrolysis have large power consumption and complex structure, the electrolytic cell needs to be maintained, and hydrogen is generated in the using process; the electrolytic copper and aluminum can not meet the antifouling requirement of large water flow temporarily, and the service life of the copper bar and the aluminum bar is short (1 year), and the use cost is high. And moreover, external power supplies are required to be introduced by adopting the anti-fouling measures of the electrolysis method, and pipelines are required to penetrate through the tanks in an anti-fouling system, so that the structural strength of the ship body is influenced to a certain extent, and the hidden danger of stray current corrosion exists.
According to a search of the prior art, for example, CN1109790C discloses an antifouling device for a structure in contact with seawater, which generates oxygen on the surface of the structure in contact with seawater to inhibit marine organisms from adhering to the surface of the structure in contact with seawater, and which has an external dc power supply with an automatic potential control means built therein. Patent CN102409353A discloses a distributed titanium alloy pipeline electrolysis anti-fouling device, and the device handles titanium alloy pipeline inner wall, utilizes external power source to produce chlorine and the effective antifouling compound of hypochlorite at the inner wall electrolysis sea water thereby reaches antifouling purpose.
In summary, the application of the anti-fouling technology in the field of marine organism fouling protection of ships is increasingly wide, but an anti-fouling measure which can be applied in the marine environment of the ship box is lacked.
