中文摘要：
空气隙膜蒸馏是一种新的膜分离技术,它可以使用太阳能等低位热能作驱动力,用于海水、苦咸水的淡化处理,在淡化水制备方面具有极强的竞争力。文章介绍的空气隙膜蒸馏实验装置,采用太阳集热装置来加热进液,通过膜蒸馏获得纯净水。结合实验数据,文章给出了料液进口温度、流量、空气隙厚度等参数对于膜通量的影响和空气隙膜蒸馏系统热容腔内对流换热传热系数的经验公式。
英文摘要：
Air Gap Membrane distillation is a new membrane separate technique.It can be used to desalt sea water and brackish water.And it can be driven by solar power, thus it has more competitiveness in desalination.The method of rotational and tangential inlet flow is adopted in air gap membrane distillation experiment device to enhance the heat and mass transfer.The effect of inlet solution temperature and mass flow and width of the air gap on the permeate flux is analyzed.The empirical equation of the convection heat transfer in the hot cavity of the air gap membrane distil-lation is proposed according to the experiment datum.
