摘　　要：The performance of a rotating packed bed （RPter solutioB） with three kinds of packings was investigated using alcohol/wan under continuous distillation conditions at atmospheric pressure. The effects of average high gravity factor （β）, reflux ratio （R）, and feedstock flux （F） on mass-transfer in distillation were examined separately. Experimental results indicated that the total number of theoretical units （NTU） of RPB increased with β, R, and F.Of the three kinds of packings, the wave thread packing of stainless steel （Packing-Ⅲ）-had the best mass transfer efficiency with the height equivalent of a theoretical plate （HETP） of approximately 7.35 mm- 23.58 ram, whereas the corrugated disk pacing of stainless steel,（Packing Ⅰ） had the worst one with the HETP of about 13.4 mm-48.07 mm.Correlations were cleveloped to describe the mass transfer efficiency for packings Comparing.experimental data with the data calculated by correlation, the average deviate obtained for each packing was 0.72%, 1.98%, and 2.7%, respectively, implying that the accuracy of correlations developed was reasonable.旋转的性能与三种包装包装了床(RPB ) 在气压在连续蒸馏条件下面用白酒 / 水答案被调查。平均高严肃因素的效果(尾) ，倒流比率(R) ，和化工物品流动(F) 在上在蒸馏集体转移独立被检验。试验性的结果显示 RPB 的理论单位(NTU ) 的全部的数字与尾， R，和 F 增加了。三种包装，不锈钢(收拾行李的 III )收拾行李的波浪线与约 7.35 公里的一个理论盘子( HETP )的高度等价物有最好的集体转移效率-- 23.58 公里，而不锈钢收拾行李的弄皱的磁盘(收拾行李我)与大约 13.4 mm-48.07 公里的 HETP 有最糟的。关联被开发为包装描述集体转移效率。把试验性的数据与数据作比较由关联计算了，一般水准背离获得了因为分别地，各收拾行李是 0.72% ， 1.98% ，和 2.7% 暗示开发的关联的精确性是合理的。
