Abstract: The separation performance of self-made inline deliquidiser apparatus was studied with air-pure water mixture as experimental medium and using weighing and variable controlling methods, and the effects of inlet velocity and liquid content on the separation efficiency and pressure drop of the deliquidiser apparatus were examined. The results show that when the inlet velocity is kept constant, the separation efficiency increases with increasing of the liquid content, then it will decline while the liquid content exceeds a certain value which increases with increasing of the inlet velocity, and the effect of liquid content on the pressure drop is not significant. The separation efficiency and pressure drop increase with increasing of the inlet velocity, in the range of the experimental droplet particle sizes (50~80 mm), when the inlet velocity increases from 14 to 22 m/s, the separation efficiency increases from 39.17% to 77.85%, and the pressure drop from 2200 to 3400 Pa. The experimental results show that the designed inline deliquidiser has good separation effect.

摘要： 以空气-纯净水为实验介质，采用称重法和控制变量法对自制的内联式脱液器的脱液性能进行了实验研究，分析了入口流速和含液量对分离效率及压力损失的影响. 结果表明，在入口流速不变的条件下，分离效率随含液量增加而增大，含液量超过一定值后，随含液量增加而下降，该定值随速度增加而增大；含液量对压力损失影响不大. 分离效率和压力损失均随入口流速增大而增加，液滴粒径为50~80 mm、入口流速从14 m/s增加到22 m/s时，气液分离效率从39.17%增加到77.85%，压力损失从2200 Pa增加到3400 Pa. 所设计的内联式脱液器脱液效果良好.
