| 摘 要： | 以乙醇-水溶液为物系,以不锈钢波纹丝网为填料,在超重力因子为20~120、原料流量0.925~1.851 mol/h、回流比1.5~4.0、原料摩尔分数0.2425、室温进料和常压操作条件下,考察了高效旋转精馏床(HERDB)运行情况与传质性能。结果显示:①高效旋转精馏床运行平稳;②高效旋转精馏床的理论塔板数随超重力因子、原料流量和回流比的增大而增加;③在实验操作条件下,高效旋转精馏床传质单元高度为9.6~65.2 mm。与实验超重力精馏设备相比,高效旋转精馏床的等板高度大于实验室超重力精馏设备,说明存在放大效应。

| Abstract: | Using alcohol/water solution system,with stainless steel wave thread packing,distillation experiment is carried out in high effective rotating distillation bed(HERDB),the running state and mass transfer property of HERDB is studied,under the conditions of ambient temperature and atmospheric pressure,average high gravity factor of 20-120,feedstock flux of 0.925-1.851 mol/h,mole fraction of feedstock of 0.2425,reflux ratio of 1.5-4.0.The results indicate that:①HERDB runs smoothly,②the number of transfer units of HERDB increases with the increasing of average high gravity factor,feedstock flux and reflux ratio,③the height of mass transfer unit of HERDB is 9.6-65.2 mm.Magnifying effect exists because the height equivalent to a theoretical plate of HERDB is more than that of RPB used in experiment. |
