提出了一种在0℃环境下,利用气流与海水溶液界面间湿度差驱动溶液自身蒸发冻结来实现海水淡化的方法,搭建了湿度差蒸发冷冻海水淡化实验装置,给出了该蒸发冷冻海水淡化产水的计算方法,对影响产水的主要因素气液界面间湿度差、气流流量进行了分析。结果表明,气液界面间的湿度差是决定蒸发冷冻海水淡化产水的关键因素,湿度差越大产水量越高;气流流量也显著影响着溶液的结冰,较大的气流流量有利于溶液的冻结,从而获得更多的产水量。
A method for desalination of seawater by evaporating and freezing the solution driven by the difference in humidity between the air flow and the seawater solution at 0 ° C was proposed. An experimental apparatus for desalination of evapotranspiration and freezing was set up, and the desalination The calculation method of water production, the main factors affecting the production of water vapor-liquid interface between poor humidity, air flow were analyzed. The results show that the humidity difference between the gas-liquid interface is the key factor that determines the water desalination of evaporating and freezing desalination. The larger the humidity difference is, the higher the water yield is; the airflow also affects the icing of the solution significantly, and the larger airflow is advantageous to the solution Of the freeze, so as to get more water production.
