Description
Technical Field
The utility model relates to a circulation system, cooling water feeding system technical field, concretely relates to closed recirculated cooling water device.
Background
The cooling water circulation system is a water supply system for cooling water to be subjected to heat exchange, temperature reduction and recycling, and cooling equipment is divided into an open type and a closed type, so that the cooling water circulation system is divided into the open type and the closed type.
The design and operation of an open system are complex, and cooling equipment comprises a cooling pool and a cooling tower which both mainly depend on the evaporation of water to reduce the water temperature. Furthermore, cooling towers often use fans to facilitate evaporation, and cooling water is often lost. The open cooling water circulation system must be replenished with fresh water. Due to evaporation, the circulating water is concentrated, and the concentration process promotes salt scaling. Make-up water has a diluting effect and its flow rate is often determined based on the circulating water concentration limit. The make-up water typically exceeds the amount lost by evaporation and blowing, so some circulating water (called blowdown) must be drained to maintain water balance. In an open system, dust, microorganisms and the like enter circulating water because water flow contacts with the atmosphere; in addition, the quality of the circulating water is also changed by the dissipation of carbon dioxide and the leakage of materials in the heat exchange equipment. For this reason, circulating cooling water often requires treatment, including sediment control, corrosion control, and microbial control. The determination of the treatment method is often related to the amount and quality of make-up water and to the performance of the production equipment. When multiple agents are used, chemical reactions that may exist between the agents are avoided. The closed cooling water circulation system adopts closed cooling equipment, circulating water flows in a pipe, and the outside of the pipe is usually radiated by wind. Except the leakage of the materials of the heat exchange equipment, no other factors change the water quality of the circulating water. To prevent salt scale in the heat exchange equipment, sometimes the cooling water needs to be softened. In order to prevent the heat exchange equipment from being corroded, a corrosion inhibitor is often added; when a high-concentration and highly toxic corrosion inhibitor is adopted, attention needs to be paid to safety, and cooling water discharged during maintenance needs to be properly treated. Generally, the closed cooling water circulation is more meaningful, and the problem to be solved is how to improve the cooling efficiency and reduce the damage of the hardness of the cooling water to the circulation system.
