Closed circuit cooling towers achieve effective contact between water and air in the following ways:
1.Well-designed sprinkler device: The sprinkler is an important part of the closed cooling tower, which can evenly distribute the water on the surface of the packing and increase the contact area between water and air. For more effective contact, a special nozzle design can be used to make the water mist more fine, while the spray angle of the nozzle can also be adjusted so that the water can evenly cover the entire packing area.
2.Choose the right filler: The filler is the medium through which water and air exchange heat, so it is important to choose the right filler. The packing should have good ventilation and heat exchange properties to maximize the contact area between water and air. In addition, the material and shape of the filler should also be able to withstand water mist and sunlight to ensure its longevity.
3.Control proper air flow: The amount of air flow directly affects the contact between water and air. If the air flow is too high, the water mist will be blown away, resulting in a shorter contact time between water and air;If the air flow is too low, the water mist will float in the air and heat exchange will not be able to take place efficiently. Therefore, it is necessary to adjust the working state of the fan according to the actual situation and control the appropriate air flow.
4.Maintain proper inlet water temperature: The inlet temperature can also affect the heat exchange efficiency between water and air. If the inlet water temperature is too high, it will cause the water temperature to drop slightly, which will affect the cooling effectIf the inlet water temperature is too low, it will cause the water temperature to drop too much and increase energy consumption. Therefore, the inlet water temperature needs to be adjusted according to the actual demand to achieve better cooling results.
Through the above measures, the closed circuit cooling tower can achieve effective contact between water and air, improve the cooling effect and reduce energy consumption.
