Background
The conventional natural ventilation counter-flow wet cooling tower (the conventional tower for short) is most used in power plants in China, and the tower type is introduced from Hamon in the eighties and ninety years of the last century, is hyperbolic and is made of reinforced concrete.
The tower type is suitable for units of 100 ten thousand and below, and the problem of uneven air distribution and water distribution is more obvious along with the increase of the water spraying area of the cooling tower, so that the performance of the cooling tower is influenced. Simultaneously along with the increase of trickle area, the water supply height increases, and the increase of pump operation charges of electricity is obvious, and economic nature is relatively poor.
The biggest difference between the high-order tower and the conventional tower is that a bottom water pool of the conventional tower is eliminated, a high-order water collecting device is added, and circulating water after heat exchange and cooling is directly collected to a circulating water system by the water collecting device below the filler.
The high-order tower has the characteristics of high efficiency, energy conservation and low noise. The high-level water-collecting cooling tower has no rain zone, small ventilation resistance, uniform air inlet in the tower, and consistent air inlet temperature of the central area in the tower and the outer ring. Compared with the conventional tower, under the same engineering condition, the water spraying area is the same, the water temperature of the high-level tower is low, and more power can be generated; the same water temperature of the tower outlet, the water spraying area of the high-level tower is small. The high-level water-collecting cooling tower can effectively utilize the potential energy of cooling water, and the lift of a circulating water pump is reduced.
In recent years, the development of power tower technology has reached a new stage. Large diameter fans, power towers with large cooling water volumes have been used in engineering.

However, in a larger unit, such as a nuclear power AP1000, CAP1400 or CAP1700 unit, the required water spraying area of the cooling tower is larger, the tower height is higher, visual aesthetics is affected, and if typhoons or tornadoes land on the local area, the safety requirement on the cooling tower is higher, which leads to an increase in the engineering quantity of the cooling tower.
