Titanium anode for circulating water descaling
The electrolysis technology to treat large-scale circulating water has been applied, and its principles are as follows:
Through the electrochemical reaction in the DC electrolysis process, the effects of descaling, sterilization, algae killing and anticorrosion are achieved. During electrolysis, the cathode undergoes hydrogen evolution reaction to generate hydroxide ions.
Description
Calcium and magnesium ions in the water precipitate and adhere to the surface of the cathode.
Then, the cathode is converted into an anode through the conductive electrode, or mechanically scraped to make the surface of the cathode attached.
The object fell off and was removed.
When the concentration of calcium and magnesium ions is lower than the equilibrium concentration of the precipitation solution, the calcium carbonate scale on the surface of the pipeline and heat exchanger will continue to dissolve, so as to achieve a complete system descaling.
In the electrolysis reaction, the most important parts, the cathode and the anode, generally use titanium with good corrosion resistance as the base material, and are coated with MMO noble metal oxides. The chlorine evolution and oxygen evolution reactions are generated at the anode, active oxygen, active chlorine, free Substances such as base have strong oxidizing properties and have a strong killing effect on bacteria and algae organisms in the water, thereby preventing the growth of fungi and the adhesion of biological slime.
Titanium anode for circulating water descaling Applications
Scaling is a common issue in industrial circulating cooling water system, which leads to the impairment of heat transfer efficiency and the burden of energy consumption. Due to huge amount of water used in industrial circulating cooling water system, controlling scale deposition in the circulating water system can ensure the safe and stable operation of the whole system, efficiently reduce energy consumption and make full use of water resources, and has significant social and economic benefits.
