摘要/Abstract

摘要： 功交换网络作为能量回收系统的重要组成部分,其设计水平的高低对过程系统的能耗将有着重要的影响,但是目前对功网络综合的研究仍处于理论研究的起步阶段.本文根据功级联分析,首次提出了一种基于转运模型进行功交换网络综合的新方法.该方法以公用工程用量最小为目标函数,建立了适用于等温过程的LP数学模型.通过提出构造低压流股压力中间值的策略,解决直接式功交换匹配过程中压力约束的限制,在每个压力间隔内寻求可行流股匹配,从而得到功交换的初始网络结构;再根据所提的合并相邻压力间隔的策略,进一步减少公用工程用量,进而达到优化网络结构的目的.最后通过实例计算,验证了本文方法的可行性及有效性.

Abstract: As an important part of energy recovery system,the design level of work exchange network has significant influence on energy consumption in process system. However,the research on synthesis of work exchange network is still in early theoretical stages. This paper proposed a new method for synthesis of work exchange network based on transshipment model in accordance with analysis of work cascade. This method took the minimum utility consumption as the objective function,establishing a LP mathematical model for the isothermal process. A strategy for constructing an intermediate pressure of low-pressure streams was proposed to solve pressure constraints in the matches during direct work exchange between work sinks and work sources. Hence,an initial work exchange network was obtained. In order to optimize the network structure,the utility consumption was further decreased according to the strategy for merging the adjacent pressure intervals. This method was proven to be feasible and effective by its applications in several examples.
