摘　　要：To improve the separation performance of a supersonic gas separation device for the treatment of gas mixture with a single heavy component, a novel structure with shorter settlement distance was constructed and a method of droplet enlargement was applied. A series of experiments were carried out in the improved separation device under various conditions, using air-ethanol vapor as the medium and micro water droplets as nucleation cen- ters. The effects of the inlet pressure, temperature and relative humidity, the swirling intensity, and mass flow rate of water on the separation performance were investigated. The separation was improved by increasing the inlet pressure and relative humidity. With the decrease of swirling intensity and mass flow rate of water, the separation efficiency increased first and then decreased. The inlet temperature had a slight effect on the separation. The results showed that the separation performance was effectively improved using the proposed structure and method, and the best separation in this study was obtained with the ethanol removal rate about 55% and dew point depression 27 K. The addition of water had little pollution to the air-ethanol vapor system since the water carry-over rate was within the range of -2 %-0 in most cases.与一个单个重部件为煤气的混合的处理改进一台超声的煤气的分离设备的分离表演，有更短的解决距离的新奇结构被构造，微滴增大的一个方法被使用。一系列实验在各种各样的条件下面在改进分离设备被执行，用象象成核中心的中等、微的水微滴的空气乙醇蒸汽。入口压力，温度和相对湿度，打漩的紧张，和分离表演上的水的集体流动率的效果被调查。分离被增加入口压力和相对湿度改进。与紧张和集体流动水评估的打漩的减少，分离效率增加了第一然后减少。入口温度在分离上有细微效果。结果证明分离表演有效地用建议结构和方法被改进，并且在这研究的最好的分离与乙醇移动率被获得大约 55% 和露水点消沉 27 K。自从水存留之物率在 &#x2212 的范围以内，水的增加有很少污染到空气乙醇蒸汽系统；在大多数情况中的 2%-0。
