摘要

Abstract

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 centers.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 pres-sure 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.
