Description

Technical Field

[0001] The invention relates to the technical field of circulating cooling water treatment devices, and in particular to a comprehensive treatment device for a circulating cooling water system. Background Art

[0002] Circulating cooling water is widely used in power, petrochemical, metallurgy and other industries. During the long-term circulation process, water evaporates continuously, causing the salt content of circulating cooling water to gradually increase, and hardness ions are prone to form scale deposited on the heat transfer surface. This will not only reduce the heat exchange efficiency, but also block the pipeline, causing great harm to normal production. In addition, circulating cooling water contains organic matter and nitrogen and phosphorus compounds. Microorganisms such as bacteria and algae will use these nutrients to multiply in large numbers in the circulating cooling water system, which will also cause great harm to normal production. Therefore, circulating cooling water needs to be effectively treated during use.

[0003] Usually, the circulating cooling water is treated by adding chemical agents such as scale inhibitors and disinfectants. Although this method is effective, the cost of the agent is high, and the scale inhibitor contains a large amount of phosphorus, which can easily cause eutrophication of natural water bodies and pollute the environment.
