一种回收蒸发潜热太阳能蒸馏装置的研究

STUDY ON A SEA WATER DESALINATION SOLAR STILL WITH RECOVERING LATENT HEAT OF VAPORIZATION

对一种回收蒸发潜热的太阳能蒸馏装置进行了研究。结果表明，太阳辐照度、冷凝器冷却海水流量和蒸发器入口海水温度是影响系统性能的主要因素，当冷凝器冷却海水流量为４５ｌ／ｈ，蒸发器入口海水温度为７５℃时，系统具有较大的淡水产量和合适的系统ＧＯＲ值。

Based on the principles of common solar desalination,a sea water desalination solar still with recovering the latent heat of vaporization has been studied.The results of the study show that the insolation,saline water load and evaporator inlet temperature of desalination unit are the main factors affecting the performance of the system.A higher fresh water production and a good GOR of the system could be obtained when the saline water load is 45 l/h,and evaporator inlet temperature of desalination unit is 75℃.
