摘　　要：基于HIDiC的理论和Aspen模拟的结果,建立了新型内部能量集成的精馏塔的塔节结构,对筛孔式结构的复合HIDiC塔节做了CFD模拟,探索了不同参数下的水力学性能,优化了新型复合塔节的结构。结果表明:对于筛孔式复合塔节,减小塔板孔径,降低出口堰高有利于提高传质和传热效果。利用SolidWorks软件针对温度与压力下的双重效应做了静应力分析,通过HIDiC理论,模型构建,水力学模拟相互验证,将HIDiC逐板换热的理论与实际模型完美结合。In this paper, based on the theory of HIDiC and the results of Aspen simulation, a new type of internal energy integration distillation structure was established, CFD simulation was conducted for the composite HIDiC with structures of sieve hole type, hydraulics properties under different parameters were explored, and the HIDiC structure was optimized. The results show that reducing the hole of the tray and the height of the exit weir can improve the effect of mass transfer and heat transfer. SolidWorks software was used to conduct static stress analysis on the dual effects of temperature and pressure. Through HIDiC theory, model construction, and mutual verification of hydraulic simulation, the theory of HIDiC heat transfer from plate to plate was perfectly combined with the actual model.
