不同热回收措施对船用多级闪蒸海水淡化装置性能影响分析

Performance Analysis of Marine Multi-Stages Flash Desalination Plant with Different Power Reserve Plants

摘要:

针对船用多级闪蒸海水淡化装置，建立热力分析模型，分别分析了部分浓海水直接循环利用和浓海水预热回收两种热回收方案在不同环境海水温度条件下加热蒸汽消耗量，计算表明，两个方案在不同环境海水温度条件下的蒸汽消耗量大致相同，但浓海水直接循环利用方案的初期投资小、维修方便，经济性优于浓海水预热方案。

Abstract: Aiming at the marine seawater desalination plant with multi-stages flash, the thermodynamic analysis model is established to conclude the heating steam consumption in different seawater temperatures at two recovery units, which are Part of the concentrated seawater recycling and Concentrated seawater waste heat. The results of calculation show that the heating steam consumption is roughly same under different seawater temperature in two solutions, but Part of the concentrated seawater recycling has some advantages as its initial investment is small and easy maintained. It is more economy than Concentrated seawater waste heat.
