3D圆阀塔板性能研究

介绍了3D圆阀塔板的结构特点和实验研究情况。以空气和水为工质进行了冷模实验,研究了3D圆阀塔板的塔板压降、雾沫夹带量和泄漏量等流体力学性能。利用氧解吸法测定其塔板效率,并在相同条件下与F1浮阀塔板进行了对比实验。结果表明,在相同条件下,3D圆阀塔板比传统F1浮阀塔板的塔板效率提高5%~15%,塔板压降约低100 Pa,泄漏量和雾沫夹带量与F1浮阀塔板基本相当,是一种综合性能优良的新型浮阀塔板。

Study on Performance of 3D Round Valve Tray

The structural features and experimental studies of 3D round valve tray are presented.The pressure drop,entrainment,weeping rate were determined by using air-water system,tray efficiency was determined by experiment of O2 desorption,and were compared with F1-type tray.When compared with the corresponding properties of F1-type tray,the tray efficiency of 3D round valve was improved by 5%~15%,pressure drop was lowered by 100 Pa,weeping rate and entrainment rate were almost equivalent to those of F1-type tray,so 3D round valve is a better valve in overall performance.
