摘　　要：在两级逆流式旋转填充床(TSCC-RPB)的基础上,采用简单结构的整体泡沫镍填料替代其相对复杂的动静环结构填料,从而构建新型两级整体泡沫镍填料旋转填充床(TSNF-RPB)。采用空气-水体系,研究了TSNF-RPB的压降特性,并以甲醇-水为工作体系,对TSNF-RPB进行了连续精馏实验研究。结果表明:虽然TSNF-RPB的湿床压降比TSCC-RPB高出了20%—30%,但TSNF-RPB的分离效率提高了20%,且TSNF-RPB结构简单、安装方便,更利于工业推广应用。In order to simplify the rotor structure of the two-stage counter-current rotating packed bed （ TSCC-RPB）, a novel two-stage rotating packed bed with nickel foam packing （TSNF-RPB） was developed.With the air-water system , the characteristics of gas pressure drop in the TSNF-RPB were studied . And the continuous distillation experiments using methanol-water binary system were carried out in the TSNF-RPB.The experimental results indicate that compared with the TSCC-RPB, the gas pressure drop in the wet TSNF-RPB is increased by 20%-30%, and the separation efficiency is increased by 20%.The TSNF-RPB is more conducive for industrial popularization and application , owing to its simple structure and installability .
