Water distribution design for super large natural draft counter flow seawater cooling tower

The water distribution system of the cooling tower is to sprinkle the hot water on the top surface of the packing evenly. The uniformity of water dripping has a great influence on the cooling effect of the cooling tower, which is directly related to the efficiency, energy consumption and investment of the cooling tower. The design of water distribution of a super large natural counter flow seawater cooling tower (17500m²) in a nuclear power plant is carried out in this paper. Based on the weather conditions and the layout scheme of the packing, the water distribution scheme is optimized by hydraulic calculation and cooling performance composition. The final scheme meets the requirements of cooling tower water distribution uniformity and winter anti freezing operation, and improves the heat transfer efficiency of the cooling tower. (author)
