Designs a wet cooling tower with an auxiliary fan and an air-air plate heat exchanger. Using the method of experimental study and numerical simulation, discusses the demisting and water saving performances. The results show that the air-air plate heat exchanger can help to increase the recovery of the water vapor at the same flow ratio. The recovery of water vapor can be up to 40% while the temperature difference is beyond 30 ℃ and the flow ratio is over 2.5, which improves the mixed effect of the ambient air and the hot humid air. Compares the experimental results with the numerical simulation results under the same working conditions, and the numerical model is reliable and predictable to investigate the demisting and water saving performances.
