摘　　要：针对已有低温精馏模拟平台,通过仿真软件进行流程模拟计算,并建立分析模型,对整个低温精馏模拟平台的各个控制体和主要部件分别进行了[火用]损和[火用]效率的仿真计算,在600 W和1200 W工况下分别达到了7.0%和12.7%的效率,对部件的优化设计是提高大型低温系统效率的关键,对流程的优化设计可提高5%以上的效率。Due to the power consumption of large-scale cryogenic refrigeration systems is huge,improving the efficiency of the system will be very meaningful,and the exergy analysis of the system and its components is an important tool for improving efficiency.Aiming at the existing cryogenic distillation simulation platform,the simulation software was used to perform process simulation calculations,and an exergy analysis model was established.The exergy loss and exergy efficiency simulation calculations were carried out on the various control bodies and main components of the entire cryogenic distillation simulation platform.The exergy efficiency of 7.0%and 12.7%were reached under 600 W and 1200 W working conditions,respectively.The optimized design of components is the key to improving the exergy efficiency of large-scale cryogenic systems.In addition,the optimized design of the process can increase the exergy efficiency by more than 5%.
