三段式聚结板气液分离器性能实验研究

Experimental Study on Performance of Gas-liquid Separator with Three-segment Coalescence Plates

为优化聚结板结构、合理选择适合于不同现场的聚结构件,针对三段式聚结板气液分离器进行了可视化实验研究;通过实验改变聚结板板倾角β及板间距b等条件,得到聚结板分离效率与气流速度、压降与气流速度变化曲线,并分析解释其分离机理。若聚结板结构参数确定,当气流速度达到9 m/s时,分离性能较为理想。当气流速度高于临界破膜速度时,二次夹带现象显著,分离效率出现下降趋势。

To optimize the structure and make a reasonable choice for different field of coalescence plates, visual experiment of three-segment coalescence plate separator is accomplished. The relationship between separation efficiency and inlet velocity as well as pressure drop and inlet velocity are obtained by changing plate angle and plate spacing of coalescence plates in the experiment. It also explains the separation theory. If the structure parameters of coalescence plates are determined, the separation performance is more excellent when the inlet velocity comes to 9 m/s. When the inlet velocity is higher than the critical rupture velocity, secondary entrainment phenomenon is obvious, and the separation efficiency declines.
