Abstract: The structural characteristics of bubbling valve tray were analyzed. In an experimental rectangular column of 1 000×350 mm, the behavior of bubbling valve tray was tested with air–water system. In the experiment, hydraulic properties, such as tray pressure drop, entrainment rate, and weeping rate were measured, and mass transfer efficiency was determined through the method of oxygen–absorptions. When compared with the corresponding properties of conventional F1 valve tray, the tray efficiency of bubbling valve tray was improved by 10%～20% , pressure drop was lowered by over 200Pa, and entrainment rate was almost the same. Bubbling valve tray, with its bubbling holes, had a larger weeping rate than F1 type tray at the low air flow rate in the experiment. However, in industrial application, the weeping rate of bubbling valve tray is almost equivalent to that of F1 type tray. The bubbling valve is proven to be a better valve in terms of overall performance.

摘要： 分析了浮阀鼓泡器的结构特点。在1 000 mm×350 mm规格的实验塔中，应用典型的水 — 空气冷模实验系统对浮阀鼓泡器塔盘进行了实验研究，测定了多种气液负荷下的塔板压降、雾沫夹带和泄漏量等流体力学性能。利用氧解吸法测定了塔板传质效率，并与F1型浮阀塔板进行了对比研究。实验结果表明，在相同条件下，浮阀鼓泡器塔板比F1型浮阀塔板的板效率提高10%～20%，板压降降低200 Pa以上，雾沫夹带与泄漏与F1阀基本相当。在小气速时，由于浮阀鼓泡器存在着鼓泡口而使得泄漏量比F1阀稍大，不过在工业应用范围内，浮阀鼓泡器的泄漏量和F1浮阀基本相当。是一种综合性能优良的新型浮阀。
