The invention discloses a kind of solar energy optical-thermal distillation devices, from left to right successively include to water cavity, vapor chamber, condensation water cavity；Free-standing photo-thermal evaporation material, several water vapour channels and hydrophobic membrane are from left to right successively arranged in the vapor chamber, the bottom of the stand alone type photo-thermal evaporation material is inserted into in water cavity；It is intracavitary that the water supply in water cavity enters condensed water after vapor chamber evaporates and to form steam.Solar energy optical-thermal distillation device provided by the invention has the characteristics that structure is simple, easily operated, avoid the membrane pollution problem as caused by directly contacting water supply and film, condensed water can efficiently be collected, it solves the problems, such as the light-blocking of condensed water and steam, improves the stability and the efficiency of solar energy utilization of photo-thermal membrane distillation system. |
