Evaluation of the operation effect of circulating cooling water treatment Monitoring heat exchanger method

1 Scope

This standard specifies the materials and equipment, methods, processes, and results calculations used for the evaluation of the operation effect of circulating cooling water treatment by the monitoring heat exchanger method And evaluation report and other technical requirements. This standard is applicable to the monitoring of corrosion, fouling and biological sludge on the heat exchanger by monitoring the bypass of the circulating cooling water system under normal operating conditions To evaluate the water treatment operation effect of the indirect cooling open circulating cooling water system.

3 Terms and definitions

The following terms and definitions defined in GB/T 10123-2001 apply to this document. For ease of use, the following is repeated Certain terms and definitions in GB/T 10123-2001. 3.1 Circulating cooling water For the purpose of directly or indirectly cooling petroleum, chemical, steel products or meeting the needs of other industrial production, returning to the cooling building after heat exchange The temperature of the material is lowered, and the water used is recycled after necessary treatment. 3.2 Circulating cooling water system A water supply system that uses water as a cooling medium and circulates. Note. It is composed of heat exchange equipment, cooling equipment, processing facilities, water pumps, pipelines and other related facilities. This standard specifically refers to the intercooled open circulating cooling water system, namely The circulating cooling water system indirectly transfers heat to the cooled medium and directly contacts the atmosphere to dissipate heat. 3.3 Monitoring heat exchanger It is a small heat exchanger that simulates the working conditions of the water cooler in the circulating cooling water system and monitors the corrosion and deposition conditions and changing trends of the circulating cooling water system. 3.4 Monitoring test tube test tube Standard metal straight pipe placed in the monitoring heat exchanger for monitoring corrosion and deposition. 3.5 Pressure drop monitoring tube Straight stainless steel pipe installed horizontally by measuring the pressure difference between both ends to monitor the amount of attached biological slime. ......
