面向空分装备重构放大设计的半实物仿真方法

o achieve the amplification design of air separation equipment, a method of physical-digital hybrid simulation for the distillation system was proposed. The concept of semi-physical simulation was introduced into the enlargement of the distillation system. Firstly, the mathematical model of cryogenic distillation system was built and translated to the simulation calculation model, so the mathematical simulation of rectification process can be carried out. A rectifying column as the main machine adopted the structure of packing. Secondly, the physical model of packed tower was constructed and investigated experimentally. The physical effects simulation of packed tower can be carried out through the similar relationship in system environments. The method of semi-physical simulation introduced the physical model of packed tower into the loop simulation of distillation system. Finally, physical and digital hybrid simulation platform of the distillation system was developed using virtual instrumentation. The platform has been verified in the design and development of large air separation equipment.
