新型高效3D圆阀塔板的实验研究

详细分析了新型高效3D圆阀的设计原理和特点. 在1000 mm′350 mm规格的矩形实验塔中，应用典型的水-空气冷模实验系统对3D圆阀和F1型浮阀两种塔盘进行了对比实验研究，测定了多种气液负荷下两种圆形浮阀塔板的板压降、雾沫夹带和漏液量等流体力学性能. 利用氧解吸法测定了两种浮阀塔板的传质效率. 实验结果表明，在相同条件下，3D圆阀塔板的板效率比F1型浮阀塔板提高约20%左右，雾沫夹带量比F1型浮阀塔板略小，在工业应用范围内，3D圆阀的板压降和漏液量均比F1型浮阀小，是一种综合性能优良的新型圆阀.

Study on High Efficiency New Tray of 3D Round Valves

The structure design and feature of a new type of 3D round valves were analyzed particularly. In an experimental rectangular column of 1000 mm′350 mm, the compared experiments between two trays equipped with 3D round valves and F1 type valves respectively were performed by employing a typical model experimental system of water-air. In the experiments, hydraulic properties, such as tray pressure drop, entrainment rate and leakage rate, were measured, and mass transfer efficiency were determined through the method of oxygen-absorption. The experimental results demonstrate that under the same condition, compared with that of the tray equipped with F1 type valves, the tray efficiency of 3D round valve is improved by about 20%, and its entrainment rate is slightly lowered. In the range of application in industry, the tray pressure drop and leakage rate of 3D round valves are both lower than those of F1 type tray. Consequently, the 3D round valve is proven to be a better valve in terms of comprehensive technology.
