采用聚丙烯中空纤维膜对纯水介质膜蒸馏、冷侧盐水循环有温差膜蒸馏及等温渗透膜蒸馏进行了实验研究,建立了描述膜蒸馏过程的传质及传热数学模型,以实验数据为基础对模型中的参数进行了回归并对数学模型进行了计算机数值求解,计算结果与实验数据吻合较好 Polypropylene hollow fiber membranes were used to conduct membrane distillation on pure water medium, thermostated membrane distillation and isothermal osmotic membrane distillation on cold-side salt water, and a mathematical model describing mass transfer and heat transfer in membrane distillation process was established. The experimental data were Based on the regression of the parameters in the model and the numerical solution of the mathematical model, the calculated results are in good agreement with the experimental data
