存在升级节点的能量/质量交换网络集成方法研究

In order to achieve high efficient use of resources and energy, the integration of heat/mass exchange networks with upgrade node are studied. Graphical method is used to reveal the insights of the interaction between the upgrade node and the network performance. The concept of pinch point is re-defined. The relationship between the composite curves with upgrade nodes and the pinch point position is explored. The dynamic composite source and sink curves after setting the upgrade node are constructed. With fitting the shape of the net sink curve as the target, the net source curve is adjusted and the pinch position is shifted by optimizing the setting of the upgrade node and its inlet and outlet potential parameters, in order to improve the network performance. The rules and principles to improve network performance by reasonably setting upgrade node will be established. The system integration theory for the heat or mass exchange networks with upgrade node will be developed. The project will deepen and extend the theory of process integration and the corresponding industrial applications.

以实现资源和能源的高效合理利用为目标，研究存在升级节点的能量/质量交换网络。为了揭示升级节点对网络性能影响的物理内涵，将采用图示法进行研究。在重新定义夹点的基础上，通过构造设置升级节点后的动态复合源线和阱线，研究源/阱线特性、升级节点位置和升级前后势参数对夹点位置和网络性能的影响，并以趋近与净阱线最贴合的净源线为目标。建立通过设置升级节点提高网络性能的规律和原则，发展具有升级节点的系统集成理论。项目将深化和拓展过程系统集成的理论基础和工业应用。
