Abstract

The invention discloses a circulating cooling water filling purification system which comprises a reservoir, a pre-ozone contact tower, a coagulative precipitation tank, a post-ozone contact tower and an electrochemical processor which are sequentially communicated, wherein a filter is arranged between the post-ozone contact tower and the electrochemical processor; an ozone generator is arranged between the pre-ozone contact tower and the post-ozone contact tower; the water outlet of the post-ozone contact tower is connected to the water inlet of the filter; the electrochemical processor is communicated with the reservoir; the reservoir is communicated with a circulating cooling tank; the circulating cooling tank is connected to a domestic water supply pipe network; a water filling pump is arranged on a pipeline between the reservoir and the circulating cooling tank; a high-low level gauge is mounted in the circulating cooling water tank; and the water filling pump and the high-low level gauge are connected to a distributed control system (DCS) in a control room. The circulating cooling water filling purification technology disclosed by the invention can be used for improving the operating efficiency and concentration multiple of circulating water, and is beneficial to energy conservation and emission reduction; moreover, the purification device is also conductive to relieving equipment corrosion during working, and the serve life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of water treatment systems, in particular to a circulating cooling water replenishment and purification treatment system. Background technique [0002] It is known that in industrial production water, a circulating water cooling system is generally used to recycle water. The cooling water that uses this method to absorb heat is generally cooled by a cooling tower. During the cooling process, a large amount of water will evaporate, resulting in the concentration of circulating water. After the circulating water is concentrated, the content of scaling substances and bacteria and algae will increase, which will cause Corrosion, scaling, slime adhesion and other problems, on the one hand, affect the service life of metal equipment, on the other hand, system scaling, slime adhesion, etc. will affect the heat exchange effect of the heat exchanger, reduce the cooling effect of cooling water, and block the pipeline ...

Problems solved by technology

The cooling water that uses this method to absorb heat is generally cooled by a cooling tower. During the cooling process, a large amount of water will evaporate, resulting in the concentration of circulating water. After the circulating water is concentrated, the content of scaling substances and bacteria and algae will increase, which will cause Corrosion, scaling, slime adhesion and other problems, on the one hand, affect the service life of metal equipment, on the other hand, system scaling, slime adhesion, etc. will affect the heat exchange effect of the heat exchanger, reduce the cooling effect of cooling water, and block the pipeline , affecting the water conservancy performance of circulating water, and the water quality problems of these systems seriously endanger the safe operation of the circulating water system

For the current circulating water treatment, the main measure is to add water treatment chemicals, so as to control the existing harmful substances in the system, so as to slow down the phenomenon of corrosion, scaling and slime, but this is only to control the harmful substances in the circulating water. In the system, when the water treatment system loses its stability, the harmful substances in the circulating water system will play its harmful role. Such a treatment method will leave potential hazards to the circulating water system.

There is no efficient and safe treatment technology for water replenishment, so we provide a water replenishment purification treatment system for circulating cooling water
