The invention provides an electro-adsorption hardness removal device and a circulating cooling water processing system and method. The electro-adsorption hardness removal device comprises a shell provided with a water inlet and a water outlet and an electrolysis pipe arranged in the shell; the electrolysis pipe comprises a hollow pipe body and a noble electrode positioned in the hollow pipe body; a preset gap exists between the noble electrode and the hollow pipe body; the hollow pipe body serves as an anode and the noble electrode serves as an cathode; the preset gap is 150-1000mm; after water enters the electro-adsorption hardness removal device, scaling ions in the water are scaled and deposited on the surface of the hollow pipes body under the action of the electrolysis pipe. The electro-adsorption hardness removal device adopts electrochemical descaling, has no pollution and meets energy-saving and environment protection requirements.
Description
technical field [0001] The invention relates to the field of water treatment, in particular to an electric adsorption dehardening device used in a circulating cooling 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. However, the traditional water treatment method of adding chemicals still has certain disadvantages in terms of expensive chemicals, high operating costs, and the phosphorus contained in the system sewage wastewater will pollute the environment. [0003] The principle of electrochemical water treatment ...
