摘　　要：提出了一个蒸馏塔板液体返混模拟和板效率计算的新模型─—等空时双平推流循环流动模型。模拟计算结果表明：该模型具有与典型的单参数混合池模型：涡流扩散模型：虚拟循环模型同样的等效性。同时，还对这几种模型值间的差异及其影响因素进行了考察。A new recycle tubular flow model with equal space time is applied to distillation plateliquid backmixing simulation and plate efficienyc calculation. The calculation results ofplate efficiency from the model and other well known one-parameter models-mixing poolsmodel,eddy diffusion model and pseudo recycle model show that the recycle tubular flowmodel with equal space time is equivalent to those well known one-parameter models.Thedifferences among one-parameter models mentioned above are also examined.
