摘　　要：热法海水淡化方法主要包括多级闪蒸、多效蒸馏、压汽蒸馏。为了降低制水成本,近年来,世界上很多国家均在努力开发热法海水淡化新技术和新工艺,并且取得了众多科研成果。探讨了国内外热法海水淡化前沿技术,包括增湿去湿法、露点蒸发、迅速喷雾蒸发、膜蒸馏、应用吸收式热泵、应用热管等海水淡化技术。针对我国对上述前沿技术的研究仍停留在实验室或模拟分析阶段的现状,提出发展建议。The thermal seawater desalination mainly includes the multistage flash desalination （MSF） process, the multiple effect distillation （MED） process and the mechanical vapor compression （MVC） distillation process. In order to reduce the cost of water production, advanced technologies for thermal seawater desalination have been researched by many countries in the world recently, and many a- chievements have been made. These advanced technologies were discussed, including humidification/dehumidification desalination, dewvaporation desalination, rapid spray evaporation, membrane distillation, application of absorption heat pumps to muhi-effect distillation and application of heat pipe to desalination. In view of that the above-mentioned advanced technologies are still at the laboratory or simulation steps in China, the development proposals were made.
