摘要/Abstract

摘要： 研究了流股混合顺序对热集成用水网络的能耗影响。首先，根据两流股的混合规则，基于热力学分析的方法研究了多流股的水网络中，不同的混合顺序对系统能耗的影响。然后，根据产生的影响结果，归纳出混合顺序的规则，可用于指导选择适当的流股混合顺序，从而提高系统节能效果。

Abstract: In this paper, the effect of mixing sequence on heat-integrated water network’s energy performance is presented. First, the effect of mixing sequence in multiple streams on system’s utility target was explored based on the heuristic rules of mixing between two streams coupled with the thermodynamics analysis method. Some rules of stream mixing sequence by investigating its effect on utility target were formulated. These rules could be used to identify the appropriate mixing sequence and improve the energy performance of a water network with several mixing scenarios, benefiting the system’s utility target.

Key words: heat-integrated water network, mixing sequence, energy saving effect, thermodynamic analysis
