Embodiment 1

[0029] figure 1 It is a structural schematic diagram of an embodiment of the application of the intelligent electrochemical water treatment device with enhanced sterilization function in the circulating water system of the present invention. Such as figure 1 As shown, the intelligent electrochemical water treatment device with enhanced sterilization function of the present invention directly pumps circulating cooling water from the cold water pool 2 under the cooling tower 1 into the electrochemical water treatment device 5 through the circulating pump P2, and the effluent returns to the cold water pool 2; Or connect a complete set of electrochemical water treatment equipment to the return water pipeline of the circulation system, use the residual pressure of the circulating water return water to introduce the circulating water into the electrochemical water treatment device, and return the effluent to the cold water pool.

Embodiment 2

[0037] The structure and treatment process of the electrochemical water treatment device 6 and the intelligent control system 5 are the same as in the first embodiment. An enterprise circulating cooling open circuit system, circulating water volume 3000m 3 / h, the circulating water system uses reclaimed water and fresh water as system replenishment from time to time according to the amount of reclaimed water, resulting in large fluctuations in the water quality of the recirculating water system. , It is more difficult to stabilize water quality by chemical agent method alone, and the device of the present invention is used to run for 30 days. The water quality parameters are shown in the table below. It shows the application reliability of the electrochemical water treatment device and the intelligent control system of the present invention.

Abstract

The invention relates to an intelligent electrochemical water treatment device with cyclically strengthened sterilization and alga killing functions. The device comprises an electrochemical water treatment device and an intelligent control system and is mounted in a circulating water system in a bypass pipeline form, wherein the electrochemical water treatment device can switch a circulating water treatment mode and a cyclical strengthened sterilization treatment mode through the intelligent control system according to feedback data of an ORP (oxidation-reduction potential) sensor mounted in a cold water tank of the circulating water system. The device can effectively remove Ca<2+>, Mg<2+> and other scale forming substances in water and reduce water hardness, also has sterilization and alga killing functions and can realize cyclical strengthened sterilization, automatic scale-removal washing and intelligent operation parameter adjustment.

Description

technical field [0001] The invention belongs to the technical field of circulating water treatment, and in particular relates to an intelligent electrochemical water treatment device used in 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. In the open circulating cooling water system, the circulating water is concentrated through the continuous evaporation of water, so that the concentration of various impurities and ions in the water is also continuously concentrated and increased, which changes the water quality characteristics of the circulating water. For example, the increase in hardness and alkalinity makes the water quality The structural tendency of the system is enhanced, and the increase in the concentration of nutrient source substances will promote the reproduction of microorganisms, making the system slime grow. Scali...
