船舶机械蒸汽压缩海水淡化装置性能分析

摘要

In the present work, by analizing the process of marine mechanical vapor desalination, the mathmatic models were gotten. As an example, the fresh water flowrate and work consumption at different evaporate temperature of a type of 5 t/d desalination system were calculation. The conclusion is that with the increasing of evaporate remperature, the flowrate of fresh water and work consumption are increasing accordingly.%在分析机械蒸汽压缩海水淡化装置工作过程基础上,给出了该型装置的数学模型.以产水量5 t/d的装置为例,分析了装置工作性能随蒸发温度的变化规律.结果表明,随着蒸发温度的提高,产水量增大,压缩机耗功相应增大.
