摘要
改进了描述含易挥发组分水溶液膜蒸镏过程的数学模型,其特点是同时考虑了两个挥发性组分在膜内和空气间隙的传质和传热,并提出了将整个膜长划分成若干微元段逐段进行计算的数学模拟方法.模拟结果与实验数据吻合较好.
A mathematical model which describes the membrane distillation of aqueous solution containing more volatile solute is improved. Mass and heat transfers of two volatile compounds in the membrane and air gap are concerned. The paper proposes a mathematical simulation method which is divided the whole membrane length into tiny sections and calculates part for part. The simulation results agree with the experimental data satisfactorily.
