随着经济的发展与人口的急速增加,淡水危机已成为人类面临的一个大问题。为了解决日益严重的淡水资源缺乏问题,人们对海水淡化技术越来越重视,目前各国研究和实际应用的淡化海水的方法已有几十种之多。蒸馏法是最早应用的海水淡化技术。这一方法虽然古老,但由于技术的不断更新改造,至今仍占统治地位。蒸馏淡化海水的过程,就是采取一定的技术手段,使海水受热蒸发成水蒸气,与海水中的盐分分离后,再冷凝成淡水。根据设备及具体流程的不同,蒸馏法又分为太阳能蒸馏法、立式长管蒸馏法、蒸汽压缩蒸馏法、多级闪击蒸馏法等。此外,以上方法的组合也日益受到 With the economic development and the rapid increase of population, the crisis of freshwater has become a major problem facing mankind. In order to solve the problem of the growing shortage of freshwater resources, people pay more and more attention to seawater desalination technology. At present, there are dozens of ways to desalt seawater in various countries for research and practical application. Distillation is the earliest application of desalination technology. Although ancient, this method still occupies a dominant position due to the continuous upgrading of technology. Distillation of seawater desalination process, is to take some technical means to make the water heated by evaporation into water vapor, and seawater salt separation, and then condensed into fresh water. According to different equipment and specific processes, distillation is divided into solar distillation, vertical tube distillation, steam compression distillation, multi-stage flash distillation and so on. In addition, the combination of the above methods is also increasingly being used
