What are the drainage methods of closed cooling towers

  The basic principle of refrigeration in a closed cooling tower is simply two cycles: one type of inner cycle and the other type of outer cycle. Without filler, the main core content is usually copper tube surface cooler, and there are others (stainless steel, carbon steel pipe, etc.).ZXDCooling tower noise reduction treatment manufacturer

  In the case of :internal circulation, it is connected with key machinery and equipment to form a fully enclosed circulation system. Realize refrigeration for key machinery and equipment, and bring the heat from the key machinery and equipment to the refrigeration equipment.ZXDCooling tower noise reduction treatment manufacturer

  When external circulation is required, in a closed cooling tower, the cooling tower itself can be cooled down. It does not touch the internal circulating water, and only realizes heat exchange and exhaust heat through the copper tube surface cooler in the cooling tower. Under this refrigeration method, the operation of the motor is set according to the water temperature through the automatic control system.ZXDCooling tower noise reduction treatment manufacturer

  The two cycles of the closed cooling tower need to run together in the spring and summer when the working temperature is high in the two seasons. The working temperature is not high in the two seasons of autumn and winter, and only one type of internal circulation is required in most cases. The water in the fins of the closed cooling tower is drained. Therefore, discussing and dealing with the drainage problems of the fins not only has basic theoretical significance for the discussion of unsteady flow, but also has practical and practical value.ZXDCooling tower noise reduction treatment manufacturer

  We get inspiration from the drainage of ordinary pipelines, whether the drainage is related to the inclination angle of the pipeline, and the drainage pipe needs to have a certain inclination when paving. The closed cooling tower is a tube heat exchanger placed in the tower, and the heat exchange of circulating air, spray water and circulating water ensures the temperature reduction effect. If the closed cooling tower does not need to operate in winter, the spray water and internal circulating water must be drained when shutting down. The cooling tower adopts a three-dimensional inclined structure in the planning of the heat exchanger to ensure that the flow of water is dredged and drained cleanly.ZXDCooling tower noise reduction treatment manufacturer

  In addition, there is also a pressure drainage method, which usually leaves an exhaust valve at the outlet of the condenser. When drainage is needed in winter, open the exhaust valve and enter from atmospheric pressure to speed up the efficiency of drainage. Together, it can be as clean as possible. drain.ZXDCooling tower noise reduction treatment manufacturer
