摘　　要：将雾化强化加湿技术引入加湿除湿海水淡化系统，搭建雾化加湿过程性能测试平台，并对不同操作下雾化加湿器内的雾滴蒸发与空气热湿过程进行实验研究。实验表明，气液体积比与进口空气温度对加湿器的加湿性能影响较大，当加湿器进口空气温度为90℃，气液体积比为（20—25）×10^3时，加湿器出口温度约为36℃，出口相对湿度在90％以上，蒸发率在50％以上。The atomizing reinforced humidifying technology was inducted into humidit cation-dehumidification seawater desalination system, and the platform for testing the performance of spray humidificati.n process was set up to carry out the experiment research of the fogdrop evaporation and air heat-humidity process in Spray humidifier and in different operating conditions. The experimental results show that the effect of gas liquid volume ratio and the air temperature in the inlet of humidifier on the humidification performance of humidifier is larger. When the air temperature in the inlet of humidifier is 90 %, the gas liquid volume ratio is between （20-25）×10^3, the temperature, the relative-humidity and the evaporation rate in the outlet are about 36 ℃, above 90% and more than 50%, respectively.
