Product Description Product Description Heat Teatment Furnace Cooling TowerThe winter temperature in the northern region is usually below zero, and the operation of the closed cooling tower anti-freezing problem is becoming increasingly prominent, if it is not solved well, it may freeze the heat exchange tube or other components of the cooling tower. According to different process characteristics, some closed cooling towers run all day in winter, some run for part of the time, and some are almost not used. But all need to consider the problem of frost protection. Working principle of closed water tower1, the closed cooling tower is actually an evaporative cooling tower, a combination of coolers and wet cooling towers, it is a horizontal evaporative cooling tower, the process fluid flows in the tube, the air flows in the tube, the two do not touch each other. Closed cooling tower is a kind of deformation and development of traditional cooling tower. After the water in the reservoir at the bottom of the tower is extracted by the circulating pump, it is sent to the outside of the pipe and sprayed down evenly. It is not in contact with the process fluid hot water or refrigerant and the air outside the pipe, and becomes a closed cooling tower, which enhances the heat and mass transfer effect by spraying water.2, closed cooling tower is suitable for a variety of cooling systems with high circulating water quality requirements, and has application prospects in power, chemical, steel, food and many industrial sectors. On the other hand, compared with the air-cooled heat exchanger, the evaporative cooling tower makes use of the latent heat of the water on the lower side of the pipe to significantly enhance the heat and mass transfer on the air side, and also has obvious advantages.Other Common type size: Anti-freezing measures in each scenarioThe winter temperature in the northern region is usually below zero, and the operation of the closed cooling tower anti-freezing problem is becoming increasingly prominent, if it is not solved well, it may freeze the heat exchange tube or other components of the cooling tower. According to different process characteristics, some closed cooling towers run all day in winter, some run for part of the time, and some are almost not used. But all need to consider the problem of frost protection.Winter basically not use the occasionIf the closed cooling tower does not need to run in winter, the spray water and internal circulating water must be emptied when it is shut down. The internal circulating water is recommended to be forced to use compressed air with a pressure greater than 4 kg, and the carbon steel tube heat exchanger is not recommended to use the way of emptying to prevent freezing. Scenarios that run in partial timeThe antifreeze of the closed cooling tower has two parts: the spray water system and the internal circulating water system (softened water).The antifreeze problem of the spray water system is usually added to the electric heater in the water tray, which is generally opened when the spray water is below 5 ° C and stopped above 8 ° C. The temperature probe transmits the signal to the control cabinet to automatically control the start and stop of the electric heater. The power selection of the electric heater is determined according to the circulating water volume and the external temperature.The antifreeze of the internal circulating water system can be added with glycol solution or electric heating equipment. The freezing temperature of the glycol solution must be lower than the local lowest temperature.For large cooling system occasions, you can consider digging a pool to spray water into it, which can save the power consumption cost of electric heating operation, and can also put drugs in the pool to improve the water quality of the spray water. The problem of frost prevention in the occasions of perennial operationThe closed cooling tower running all year round, if equipped with an electronic control system, may change the number of cooling tower operation due to the load change of the main system, so it is also necessary to consider the problem of antifreeze. Unused equipment can be emptied before winter to prevent freezing.With the continuous development of science and technology, closed cooling towers will inevitably usher in greater development and application space.
