| 摘 要： | 利用夹点技术对一个复杂化工换热网络进行了用能诊断，并结合流程模拟技术新设计出一个能量回收量最大的换热网络。在用断开热负荷回路的方法对所得到的新换热网络进行调优时，发现一些热负荷回路出现了与以往夹点技术论述中所没有提及的新特点。用常规的方法对这些特殊的热负荷回路进行断开已不太适应，对此提出了解决的办法，并借助流程模拟技术对此方法进行检验。结果表明，通过调整有关参数消除了新网络在实际运行中可能出现的问题。因此，采用流程模拟技术，可使夹点技术更好地应用于实际的换热网络设计中。

| Abstract: | The energy consumption of a complicated heat-exchange network in chemical industry was studied with pinch point technology and the technology of flow simulations.A new design was provided which reclaims the greatest remained energy.It was found that some special loops in heat-exchange network have some new characteristics which have not been mentioned in former dissertations,while optimizing the new designed network through disconnecting the loops in the network.It was not appropriate for disconnecting thes... |
