| 摘 要： | 针对基于传统旋转填料床(RPB)和折流旋转床(RZB)开发的一种新型多级逆流式超重力旋转床(MSCC-RPB),在常压下通过以乙醇-水为研究体系的连续精馏实验对MSCC-RPB的精馏性能进行了研究。分别考察了旋转床转速(N)、进料浓度(xF)、进料热状况(q)、回流比(R)对MSCC-RPB的理论塔板数(NT)的影响规律。结果表明:MSCC-RPB的NT随N的增加先增大后减小,随xF的增加变化不大,随q的增加而增大,随R的增加而增大;在实验考察范围内,最佳操作转速为800r/min,MSCC-RPB理论塔板高度在19.5～31.4mm之间;与传统两台RPB连续精馏的理论塔板高度相当,与RZB相比传质效率提高近一倍且最佳转速更低。

| Abstract: | Continuous distillation experiments have been carried out in a novel multi-stage counter-current rotating packed bed (MSCC-RPB),which was developed by taking into account the advantages and disadvantages of a conventional rotating packed bed (RPB) and a rotating zigzag bed (RZB),using the alcohol-water binary system at atmospheric pressure to study its separation performance. The effects of varying the rotation speed (N),feedstock concentration (xF),thermal conditions of the feed (q) and reflux ratio (R) on... |
