摘　　要：在用虚拟温度法得到的间歇过程换热器网络综合的基础上,对间歇过程换热网络的结构优化问题进行了研究。主要内容包括:在以时间段模型为基础,用虚拟温度法综合间歇过程得到的直接换热网络的基础上,寻找各时间间隔的子换热器网络内的热负荷回路;以一定的规则断开回路,对总换热器网络进行结构优化,使最后的总换热网络既能够减少换热单元数目,又满足年度总费用最小。The structure optimization of heat exchanger network for batch processes was studied with the heat exchanger network based on pseudo-temperature.Based on the Time Slice Model,the direct heat exchanger network for batch processes was synthesized by replacing approach temperature with pseudo-temperature,and the thermal load loops could be determined within each time interval of the heat exchanger network.According to specific rules to disconnect loop of the heat exchanger network,structural optimization for the final network was performed to reduce the number of the heat exchanger units and to meet the minimum annual cost.
