摘　　要：海水淡化技术对于远洋船舶营运具有重要意义。为优化船用淡化装置,对蒸馏法海水淡化利用分析的方法,建立了及效率方程,分析了蒸发器损的原因,并建立了损方程,得出了影响效率的主要因素是温差和流动阻力,从而为船用淡化装置的优化改进指明了方向。Sea water desalinization technology is of great significance for the operation of ocean-going vessels.In order to optimize the marine desalination devices,exergy and exergy efficiency equations,for the distillation way of sea water desalinization,are set up by making use of the method of exergy analysis.At the same time,the causes of evaporator exergy loss are analyzed,and exergy loss equations are set up.Finally,it comes to the conclusion that the difference of temperature and flow resistance are the main factors influencing the exergy efficiency.And by this way,it is not so difficult to find out the way of how to optimize and improve the marine desalination devices.
