Power and chemical plants entail serious water loss during their operation. In order to save water by alleviating the loss of the circulating water in the cooling tower, a FLUENT simulation is performed to design and analyze a cyclonic water collector. The geometrical structure of the collector was such designed that the trajectory of the steam is optimized. The turbulence caused by the collector increases the possibility for collisions between water molecules, and the accumulation of tiny drops could be recycled. The results of the numerical simulation and the experiment verification demonstrate the ability of the proposed device to save much water. Furthermore, the mechanisms for water recycling and water saving are elucidated clearly through the gas-liquid coupling of the circulating water and cooling water. The present theory gives deep insights into the optimization of water-saving facilities and improvement of water-saving efficiency.
