In order to realize the high efficiency, environmental protection and energy saving of the mechanical ventilation cooling tower, through the research on the mechanism of the feather mist generated by the cooling tower, the Mechanical Ventilation Cooling Tower Condensing and Collecting Waterand Anti-fog System was designed, and the feasibility method of cooling tower water saving and fog elimination was proposed. The confined space cooling tower(CSCT) and the free space cooling tower(FSCT) condensing water collection and anti-fog devicewere designed.The partition wall heat exchanger was used as the design mode of the condensing device, which was assembled by using a heat exchanger plate with simple structure. Through the example design calculation, the effect of the condensing water collection and anti-fog device has obvious water saving benefits. It provides theoretical basis and technical support for the upgrade of the cooling tower and the design of the new cooling tower.
