How many degrees can the cooling tower be cooled to the water? In fact, from the principle of the cooling tower, it is very simple. Hot water exchanges heat with the air in the filler. To a large extent, the heat exchange is flat and the air temperature is flat, and the heat exchange is suspended. Therefore, the temperature of the cooling water is the same as the environmental temperature. But another point cannot be ignored that the steaming of water needs to absorb heat. The steaming of water will reduce the water temperature.
The more dry the air, the more severe the steaming, and the lower the water out of the cooling tower water receipt. Therefore, the temperature of the output of cooling water is determined by two aspects: heat transfer and steaming. These two aspects determine that the temperature of the cooling water will be lower than the ambient temperature and higher than the wet ball temperature. Use the cooling tower to collect and reuse the cooling water.
Cooling tower water collector structure: spray down through the pipeline of the tower. In addition, there is a fan on the wall of the tower to blow into the air. There is a large exhaust fan on the top of the tower to suck the air on the top of the tower to promote air activity and accelerate the cooling of water. On the top and bottom of the water spray pipe, there is a twisted hollow polyvinyl chloride plastic heat sink to increase the heat dissipation time of water droplets.
Planning into such terrain requires bilateral shapes, which will be more conducive to exchange heat exchange between water and air. The cooling tower is mainly used in air -conditioning cooling systems, refrigeration series, aluminum profile processing, turbines, rectification, power generation, injection molding, foam, air compressor, industrial water cooling and other fields.
Many cooling towers still use air -conditioning cooling, refrigeration and plastic industries. Some waste heat generated during industrial production or refrigeration is usually taken away by cooling water. At this time, the effect of the cold water tower is to exchange heat exchange with the air in the tower, then pass the waste heat to the air, and then pass it to the atmosphere.
For example, use the cooling tower water collector in thermal power plant. Heating water in the boiler to form high temperature and high pressure steam. Therefore, promoting the work of steam motors can generate generators. After the steam turbine work, the exhaust gas generated will be discharged into the cold water tower condenser, and then the cooling water is exchanged with the cooling tower, condensed into water, and then pumped. Return to the boiler for recycling. In the process, the waste heat of the exhaust gas was passed to the cooling water of the cold water tower, which increased the water temperature and carried the waste heat of cooling water.
