Problems solved by technology

[0005] However, the existing electrochemical water treatment devices generally have shortcomings such as a single metal electrode composition in the electrode group, weak durability of the electrical treatment performance, easy aging of the electrodes, and poor corrosion resistance; corresponding to different treatment water qualities, there is a lack of sensitivity to adjust operating parameters More targeted intelligent automatic control system; lack of descaling treatment process and suitable mechanical devices, resulting in more scale deposits on the electrode plates in the electrode group, which will have a greater impact on the subsequent electrochemical water treatment process and reduce water pollution.

Abstract

The invention discloses an electrochemical water treatment device and an intelligent control system for a circulating water system. The electrochemical water treatment device is characterized by being capable of being used as a bypass pipeline for treating quality of circulating water, and comprising an electrochemical treatment device (6) and an intelligent control system (5), wherein feedback data of a current and voltage sensor (26) in the electrochemical treatment device (6) and feedback data of a residual chlorine sensor (7) in the circulating water system are used as input information of the intelligent control system (5), so that an automatic descaling and cleaning step and an intelligent operation parameter regulation of the electrochemical treatment device (6) are realized.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an electrochemical water treatment device and an intelligent control system for a circulating water system. Background technique [0002] The circulating water system is one of the indispensable energy media for the production of metallurgy, energy and chemical enterprises. At present, for circulating water treatment systems, in order to reduce the adverse effects on pipelines and equipment caused by the concentration of salts in circulating water, the method of adding chemical agents is generally used to maintain stable water quality and increase the concentration multiple of circulating water systems. [0003] However, the traditional water treatment method of adding chemicals still has certain disadvantages in terms of expensive chemicals, high operating costs, and the pollution of the environment caused by the phosphorus contained in the system sewage wast...
