摘要
应用空气-富氧水系统,在直径1200mm不锈钢塔内对HEFV固阀塔板进行了实验研究。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。
New HEFV （half-ellipse fixed valve） tray which has some improvements on traditional fixed valve trays was presented. The hydrodynamic and mass transfer performance of HEFV tray,sieve tray and F1 valve tray were experimentally studied with air-water-oxygen system in a 1200 mm stainless steel column. The re.ults show that HEFV tray possesses a little higher pressure drop,less entrainment,lower weeping and higher efficiency than sieve tray as well as tower pressure drop, less entrainment, higher. weeping and higher efficiency than F1 valve tray,which demonstrates that HEFV tray owns super performance.
