Simulation of a Gas/Liquid Separator

对气液分离器模拟实验技术进行了研究 ,其核心是分离效率的准确测量和实验过程中雾滴粒度及浓度的控制。采用稀盐水 -空气作为实验介质 ,通过测定进出口盐水中Cl- 浓度的变化计算蒸发率 ,进而得到分离效率。该分离效率的测量结果不受空气湿度和温度的影响 ,误差小于 0 5 %。考察了双流道喷嘴雾化粒径的影响因素 ,并提出了雾滴粒度及浓度的控制方法 。

Simulation experiment on a mist separator was carried out.The aim was to determine the separation efficiency and to precisely control droplet concentration and size.Brine-air was used as experimental media of the system.Mist separation efficiency was quantitatively determined by electrochemically measuring concentration variation of Cl - ion during process.As a prominent feature,this system could avoid effects of ambient atmospheric temperature and moisture on separation and thus provided a reliable way for the study of gas-liquid separation.Key effects of droplet concentration and droplet size on mist separation efficiency and measure of control was determined.A mathematical model for controlling droplet size during mist forming by a dual-flow nozzle was set up.
