Research of entrainment and tray pressure drop of new directed bridge valve trays;

新型导向桥阀塔板的雾沫夹带和塔板压降

Equations of hydraulic parameters such as pressure drop,weeping and entrainment were regressed.

采用空气-富氧水体系,在φ1200 mm不锈钢塔内,对百叶窗式喷射塔板的流体力学与传质性能进行了测试,回归了压降、泄漏、雾沫夹带等计算关联式,并与新垂直筛板进行了对比实验。

The results show that HEFV tray possesses a little higher pressure drop,less entrainment,lower weeping and higher efficiency than sieve tray as well as lower pressure drop,less entrainment,higher weeping and higher.

结果表明,HEFV固阀塔板的压降介于筛孔塔板与F1浮阀塔板之间,雾沫夹带率低于筛孔塔板和F1浮阀塔板,泄漏率比筛孔塔板低,比F1浮阀塔板高,传质效率优于筛孔塔板和F1浮阀塔板。

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.

在1000mm×350mm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。

From the experiment,many hydraulic properties,such as tray pressure drop,entrainment rate,weeping rate and tray efficiency, were measured and mass transfer efficiency wa.

在1000 mm×350 mm规格的实验塔中,以典型的水-空气冷模实验系统,对锯齿边窄条阀STV75塔盘和F1圆形浮阀塔盘进行了对比实验,测定了多种气液负荷下的压降、雾沫夹带、泄漏量等流体力学性能。

The hydraulic properties,such as tray pressure drop,entrainment rate,and weeping rate were measured,and the mass transfer efficiency was determined through the method of oxygen-absorptions.

应用典型的水-空气冷模实验系统对3D条阀、STV条阀和F1型浮阀3种条阀进行了对比实验研究,测定了多种气液负荷下3种浮阀塔板的板压降、雾沫夹带和漏液量等流体力学性能,利用氧解吸法测定了3种浮阀塔板的传质效率。

The results show that the entrainment mechanism is a more dominant fibre loss mechanism than bubble-fibre adhesion mechanism during flotation.

结果表明:浮选时纸浆中纤维和细小纤维流失的雾沫机理较粘附机理更有说服力,更能了解浮选时纤维和细小纤维流失的原因和防止流失应采取的措施。
