Why Should We Install An Electrolytic Seawater Chlorine Plant?
Seawater pipelines and cooling systems in coastal nuclear power plants are susceptible to biofouling, causing problems such as corrosion of alloy steel or carbon steel pipelines, blockage of pipelines, pollution of circulation systems, reduction of heat exchange efficiency, failure of components, and damage to instruments. In order to avoid the attachment, growth and reduction of pollution of marine organisms, and to make the nuclear power plant economically and safely operate, special electrodes can be used to directly connect the direct current to the natural gas without the diaphragm, so that the sodium chloride and chloride ions in the seawater react at the cathode and the anode. Under the action, it produces effective chlorine with strong oxidation, and uses effective chlorine to stun, destroy and kill marine microbes, plant and animal tissue cells. The chlorine production device and the chlorine production system can simultaneously generate a chlorine evolution reaction and an oxygen evolution reaction when electrolyzing seawater, and have high requirements on electrode performance and chemical performance, and the electrochlorination plantdesign and manufacture should be reasonably used.
Seaweed, tube hook shrimp, sea squirt, bryozoan, barnacle and other marine organisms can degrade the cooling system and seawater pipeline of the coastal nuclear power plant, increasing the cost of cleaning and maintenance of power station equipment, affecting power generation. Electrolyzing seawater is environmentally friendly in preventing fouling. Anti-fouling is thorough and long-lasting. The temperature and composition of seawater can change with the location and season of the sea. In order to improve the anti-fouling efficiency, the chlorine-making device should be installed and debugged reasonably, and the parameters such as current efficiency, voltage and power consumption should be controlled, the anode should be selected scientifically, and the performance of the electrode can be improved to reduce the cathode. The problem of black film, calcium-magnesium salt and anodic corrosion is deposited, so that the electrolysis process, cell voltage and current efficiency of the chlorine system can adapt to seawater composition and temperature changes, and improve the selectivity, current density and current efficiency of the system electrolysis reaction.
