摘要
在常温常压条件下对2个简化试验件进行了空气-水混合物的两相可视化分离试验研究.通过改变入口空气流量、入口水体积分数以及入口液滴粒径等条件,测量并获得试验件的汽水分离效率以及阻力曲线.结果表明:2个试验件的内筒内壁均形成明显水膜,在各试验工况下分离效果良好;带有切向口的试验件2的分离水在切向出口和下降通道中的分布受入口空气流量和水流量的影响较大;试验件2的总阻力及旋叶阻力均大于试验件1的;入口液滴粒径对分离效率无显著影响.
Visualized separation tests were carried out on air-water two-phase flow in two small-sized mois- ture separators at normal pressure and temperature. The steam-water separation efficiency and resistance curve of above two separators were measured at different inlet air flows, different volumetric fractions of inlet water and different sizes of inlet water droplets. Results show that for both the separators, obvious water film forms on inner surface of the inner tube, indicating good separation performance under different conditions. For separator 2 with tangential ports, the distribution of separated water at the tangential out- let and in the downward path is greatly affected by both the air and water flows. The total and vane pres- sure drop of separator 2 are higher than separator 1. The size of inlet droplets basically plays no role in in- fluencing the separation efficiency.
