Description
Technical Field

Background
The cooling tower for cooling the circulating water of the main engine or the auxiliary engine of the thermal power plant has two common cooling modes, namely a dry cooling mode and a wet cooling mode. The dry cooling tower uses air as a cooling medium, and the air exchanges heat with cold air through a cooling triangle (heat exchange equipment) to cool circulating water, so that water is hardly consumed in the cooling process. The working principle of the wet cooling tower is as follows: the water is sprayed on the filler, and the circulating water is cooled through the mass transfer and heat transfer exchange process generated by air and water, so that the water consumption is high.
Although the dry cooling tower has a remarkable water saving effect, when the environmental temperature is high (such as summer), the water temperature of the circulating water often cannot meet the requirements of power generation equipment (the water outlet temperature is higher), so that the application of dry cooling is greatly limited.

Because the installation position of the dry-cold section is high, the height difference between a cooling triangle (radiator) of the dry-cold section and the outlet of the tower body is small, and the operation draft of the dry-cold section is also small (the draft formed by natural ventilation is related to the height difference between the radiator and the outlet of the tower body, namely the effective height);
