【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 level of power exchange network design will have an important impact on the energy consumption of the process system. However, the research on power network synthesis is still in the initial stage of theoretical research.Based on the analysis of power cascade, a new method of power exchange network synthesis based on transfer model is proposed for the first time in this paper.The LP mathematical model suitable for isothermal process is established by taking the minimum consumption of public works as the objective function.By putting forward the strategy of constructing the intermediate value of low pressure stream pressure, the limitation of pressure constraint in direct power exchange matching process is solved, and the feasible flow stock matching is sought within each pressure interval, and the initial network structure of power exchange is obtained.According to the proposed strategy of merging the adjacent pressure interval, the utility consumption is further reduced and the network structure is optimized.Finally, the feasibility and effectiveness of the proposed method are verified by an example.
