MSF系统级数的选择

Making Choice for Stage Number of Multi-stage Flash Desalination System

本文通过分析级数与淡水产量、造水比、传热面积及(火用)损失的关系,详细地说明了级数对系统的热力学性能和经济性的影响,并推演出了确定排热段级数的方法。然后针对不同的情况综合分析给出了级数的合理范围。

In this paper,the relations between stage number and distillate production performance ratio, heat trans-fer area or exergy loss are minutely analyzed. The influences of stage number on the thermodynamic property and economy of the system are detailedly discussed. The approximate method for determining the stage number of heat rejection section is derived. Finally, the reasonable ranges of stage number in accordance with different conditions are given.
