摘要

Since the world’s first large-scale solar desalination plant was built,there has been no breakthrough in passive solar desalination technology.The reason for this is that the problems of photothermal conversion,evaporation and condensation have not been properly solved.As a hot research topic at present,solar interface evaporation technology is only an improvement of disk solar desalination technology.The solar evaporation technology sets the heating surface,evaporation surface and condensing surface from top to bottom.It has high efficiency of photo-heat conversion,large amount of seawater evaporation and good condensation effect.Some of that heat is recycled,and it is used to heat seawater,which is a disruptive technology.We have seen the development of passive solar desalination technology that Disk solar desalination technology is the starting point,solar interface evaporation technology is the current research hotspot,and solar evaporation technology with overhead heating surface will be the end of the whole process.
