Problems solved by technology

[0004] (2) Microbial growth: The open circulating cooling water can convolute dust and microorganisms (and their spores) in the air during the heat dissipation process in the cooling tower, resulting in an increase in system turbidity. At the same time, microorganisms such as bacteria and algae are suitable for cooling water systems. will grow rapidly under the conditions that lead to the growth of systemic microorganisms
[0007] Although the chemical treatment method of circulating cooling water is effective, it has obvious disadvantages: first, a large amount of chemical agents are used, most of which are harmful to the environment and have poor environmental compatibility; As the concentration of cooling water increases continuously, the drainage of the sys

Embodiment 1

[0054] (1) Overview

[0055] The cooling system of pure water filling production line of Shenyang Zhongfu Preform Co., Ltd. was selected as the experimental research object. This system is mainly used for cooling of pure water canning production equipment, with a scale of 50m 3 / h. Due to the lack of professional maintenance personnel, the water replenishment of the system is controlled by the opening of the water replenishment valve controlled by the float level gauge. In addition to the wind loss, the system rarely drains water, resulting in a long-term extremely high concentration multiple (according to the conductivity and hardness test results) It is judged that the system is operated under the condition that the concentration ratio of the system is greater than 600 times), and the system rarely performs chemical treatment and maintenance, resulting in serious scaling and corrosion of the system. less than 2 degrees Celsius.

Abstract

The invention relates to a water direct-current electrolytic treatment process for circulating cooling and direct-current electrolytic treatment equipment for the circulating cooling, and shows the core concept that a bypass circulating system is arranged on a circulating cooling water system, and the direct-current electrolytic treatment equipment is arranged to treat the circulating cooling water. The direct-current electrolytic treatment equipment is used for scaling and separating out calcium and magnesium in the circulating water by utilizing cathodic hydrogen evolution reaction, and descaling and discharging the scale to continuously reduce the hardness of the system so as to preventing scale from generating; active materials separated from a specially dimensionally stable anode are utilized for exterminating bacteria and inhibiting the growth of bacteria, so that the problems due to blocking and corrosion are prevented; and simultaneously, the pH is increased by hydrogen evolution reaction, so that electrochemical corrosion can be effectively prevented. The direct-current electrolytic process realizes a plurality of functions in the same process, such as descaling, sterilizing and exterminating the bacteria. Compared with the conventional physical method and chemical method, the direct-current electrolytic treatment process has the advantages of being remarkable in effect, high in cleanability, capable of saving water source, low in energy consumption and low in cost, and can realize unattended operation.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and mainly relates to a circulating cooling water treatment process and equipment, in particular to a circulating cooling water direct current electrolytic treatment process and equipment. Background technique [0002] Industrial production equipment and building air conditioning systems need to be cooled, and water is the most commonly used cooling medium. Industrial cooling water consumption is very large, accounting for more than 2 / 3 of the entire water consumption, and cooling water in many industries accounts for 80% to 95% of the total industrial water consumption. The number of building air-conditioning systems is huge. It is estimated that there are several million central air-conditioning units in the country, and the cooling water consumption is very large. In order to save water resources, cooling water is usually required to be recycled, which is called circulating cooling w...
