Brief discussion on the water-saving principle of closed cooling tower

A closed cooling tower is a device that uses water for heat exchange. It has been widely used in modern industrial production and civil fields for its water quality protection, water and energy saving, precise temperature control, reduced maintenance costs, strong environmental adaptability, low noise, easy installation and movement, and strong scalability.

The water-saving principle of a closed cooling tower is mainly reflected in its unique circulation system and working mode. The following is a detailed analysis of the water-saving principle:

Water-saving in the internal circulation system

1 Closed circulation: The internal circulation water of the closed cooling tower circulates in a closed coil, completely isolating the outside air, thus avoiding the evaporation and consumption of water. Compared with the traditional open cooling tower, this design saves a lot of water resources at the source.

2 Constant temperature regulation: The internal circulation system is usually equipped with a constant temperature regulation device, which can adjust the water temperature according to the actual needs of the production equipment, further improving the water use efficiency and avoiding unnecessary waste.

Water-saving in the external circulation system

1. Spray water circulation uses the spray pump of the closed cooling tower to draw water from the sump, spray the water evenly on the coil surface, and exchange heat with the pipe wall. The unevaporated water droplets return to the sump through the dehydrator, realizing the reuse of the spray water. This design significantly improves the recycling efficiency of water.

2 Low floating water rate: Since the closed cooling tower is a closed working environment, the spray water rarely floats during the spraying process, further reducing water waste.

3. Intelligent working mode water saving

1. Dry and wet mode switching: The closed cooling tower has two operating modes, dry and wet, which can be automatically adjusted according to conditions such as outlet temperature, working conditions, season and whether local water resources are sufficient. When the outlet water temperature requirement is high, only the air cooling mode can be turned on and the spray system can be turned off to save water resources. In spring and summer, when the ambient temperature is high, turn on the air cooling + spray mode, and in autumn and winter, when the ambient temperature is low, it may only need to turn on the air cooling mode.

2 Intelligent control: The closed cooling tower is also equipped with an intelligent control system that can automatically adjust the operating parameters of the spray pump and fan according to the changes in the circulating medium outlet temperature and ambient temperature, ensuring that water resources and electricity are saved to the maximum extent while meeting the cooling needs.

The closed cooling tower achieves efficient water-saving effects through its unique internal and external circulation system and intelligent working mode. The extensive application of closed cooling towers in industrial production can not only reduce water consumption and operating costs, but also help achieve sustainable development goals.
