THEORY AND PRACTICE ABOUT THE ELIMINATION OF SALTED FOG AND FROTH BY COMBINING MAIN PRESSURE FLOW WITH ASSISTANT OPEN-CHANNEL FLOW
The heated discharge from the condenser circulating water withdrawn from Dayawan Estuary generates a hydraulic jump on the apron to dissipate energy when it falls down with high velocity over the weir. Under the hydraulic jump, a lot of the salted fog spattered will erode the equipment near the outfall, and the light yellow froth formed by entrained air bubble on water surface has influences on the ocean environment around the nuclear power station. Based on the analysis, it can be seen that the necessary condition of the froth formed is entrained air and the sufficient condition of not disappearing easily is the water quality. The way of eliminating the fog and froth by combining main pressure flow with assistant open-channel flow was put forward in this paper. The ideal has been applied to reforming the project about the heated discharge outfall (CC) in Dayawan Nuclear Power Station. In order to enhance the proportion of the pressure discharge and to decrease entrained air in free flow by many synthesis measures, the project layouts has been optimized by making use of a big-scaled hydraulic model. A new experiment method is to put some chemical solution into the water in the model to simulate the froth. Results of the model test have been verified by data obtained in the prototype observation.
