Power plant circulating water descaling sterilization ruthenium-iridium titanium anode

Electrochemical water treatment technology circulating water descaling

Circulating water system is one of the essential energy medium of metallurgy, petroleum, chemical, pharmaceutical and building central air conditioning system. Improving the utilization rate of circulating water will greatly reduce the water pressure. However, reducing the discharge of circulating water and improving its utilization rate will inevitably lead to scaling, corrosion and large number of microorganisms breeding in pipelines and equipment. At present, for industrial circulating water treatment system, in order to reduce the adverse impact on the pipeline and equipment caused by the concentration of salt in circulating water, the method of adding chemical agents is widely used to keep the water quality stable and improve the concentration ratio of circulating water system. However, the agents used in this method are expensive and expensive to run. Electrochemical water treatment technology utilizes the electrochemical characteristics of water and minerals in water, and by adjusting the balance of minerals in water, solves the three major problems of scale formation, corrosion and algae breeding of industrial circulating water, and fundamentally solves the environmental pollution caused by the addition of chemical agents.

Principles of electrochemical water treatment technology

The main principle of electrochemical water treatment technology is the use of titanium electrode electrochemical REDOX reaction, the water Ca2+, Mg2+ in the form of solid adsorption in the cathode after removal, reduce the hardness of the water, while producing some strong oxidizing substances, inhibit the cooling circulating water system in the breeding of fungi algae, to achieve the function of sterilization and algae.

Principle of electrochemical circulating water descaling

Under the action of current, electrolytic reaction occurs in the water at the cathode to generate hydroxide ions. The hydroxide ions generated by the cathode reaction break the balance of alkalinity and hardness in the solution near the cathode. Meanwhile, the calcium and magnesium plasma in the water migrate to the cathode area under the action of electric field, forming calcium carbonate and magnesium hydroxide precipitation respectively. At the same time, calcium carbonate crystallizes on the surface of cathode plate under the action of electric field, which is easy to peel and remove.

Principle of electrochemical circulating water sterilization

Electrochemistry is not a simple process. It includes a variety of action mechanisms and reaction processes, such as physics, chemistry and biology, and can be considered as a result of the combined action of a variety of factors. Under the action of electric field, the chloride ion in the water will 衱 oxidation into chlorine free chlorine components, such as, hypochlorite, hypochlorous acid root electrolytic chlorination, mainly through hypochlorous acid. Hypochlorous acid is a small, neutral molecule that acts as an oxidizing agent that destroys bacteria and kills them. In electrocatalytic reactions, the electrolysis of water and oxygen dissolved in water generates some short-lived intermediates on the surface of the electrode. These highly oxidizing substances can oxidize various components of the microbial cell, resulting in irreversible changes and death of the microbial.
