This creation is related to the technical field of cooling water tower water distribution system, especially an adjustable water distribution system for cooling water tower anti-fogging and energy saving.

The cooling water tower system uses evaporative cooling to cool hot water into cold water, and is generally widely used in air-conditioning circulating water systems and industrial circulating water systems. The main purpose is to send the hot water produced by the cooling effect to the upper end of the cooling water tower, and then flow down after forming a larger area through nozzles or other means of dispersing water. Then use the fan device to force the cold air outside the tower into the cooling water tower, then the downwardly flowing hot water and the cold air entering the cooling water tower exchange heat at the radiator, so that the water temperature is reduced to cold water, and the heated gas Then the outflow water tower is dispersed in the air.

The design of the water distribution system of general cooling water towers is usually aimed at the maximum design water volume, including main pipes, branch pipes and sprinklers. When the circulating water volume is at the design value, ensure that the sprinkling water of the cooling water tower can be evenly distributed on the filler.
