Antifouling device based on platform steel pile ring type electrolytic antifouling electrode and its realization method

Abstract

The invention relates to a fouling prevention device based on platform steel pile ring type electrolysis antifouling electrodes. The fouling prevention device comprises a controllable power supply, wires, the positive electrodes and the negative electrodes. The positive electrodes and the negative electrodes are all in an annular shape, arranged outside steel piles in a sleeving manner and connected with the controllable power supply through the wires correspondingly. A method includes the steps that the positive electrodes and the negative electrodes are prepared and connected with the controllable power supply; the controllable power supply outputs direct-current voltage so that a loop can be formed by the controllable power supply, the positive electrodes and the negative electrodes; and seawater is electrolyzed on the positive electrodes to generate Cl2, OH- is generated on the negative electrodes, the available chlorine concentration gradient is formed around pile legs, and organisms are prevented from adhering to the pile legs of a platform. By means of the fouling prevention device and the method, the effect of preventing and controlling organism adhering is achieved by electrolyzing the seawater through the controllable power supply to generate available chlorine. The controllable power supply has the beneficial effect that the power-on period of the whole closed loop can be controlled, and therefore the real-time fouling prevention effect is achieved. The preparation process is simple, operation is easy, controllability is high, performance is reliable, and the device is simple in structure and convenient to manage.

Description

technical field [0001] The invention relates to the field of preparation of marine environment antifouling devices, specifically a direct electrolytic antifouling device suitable for ocean platforms and its realization method, suitable for preventing the adhesion of organisms in marine environment materials, as well as marine steel pile bridges, Monitoring of platform cathodic protection. Background technique [0002] Since the development and utilization of marine resources, human beings have been plagued by the problem of fouling caused by marine organisms. Marine adherent microorganisms, plants and animals cause adhesion fouling on artificial ocean mobile and fixed facilities, and cause various hazards to these artificial facilities, collectively referred to as marine biofouling. The jacket of the offshore platform is in an open seawater environment, and is subject to double hazards of seawater corrosion and marine biofouling. [0003] Electrolytic seawater anti-fouling...
