【摘要】 介绍了一种新型塔板——双层导向浮阀塔板,该塔板综合了国内流行的导向条阀与国外广泛使用的微型固阀的优点。采用空气-水体系,在直径为600 mm的塔内,对双层导向浮阀塔板的流体力学与传质性能进行了测试,并与F1浮阀塔板进行了对比实验。结果表明,双层导向浮阀塔板具有操作弹性大、压降低、雾沫夹带和漏液小以及传质效率高等特点,综合性能优于F1浮阈塔板。更多还原

【Abstract】 Double layer guide valve tray, combining the advantages of guide rectangular valve tray and micro V -Grid fixed valve, was presented. The hydraulic and mass transfer performances of double layer guide valve tray and F1 valve tray were investigated with air - water system in a column of 600 mm internal diameter. The experimental results show that double layer guide valve tray offered better operation flexibility, lower pressure drop, less entrainment and liquid weeping, and high efficiency, compared to Fl valve tray.更多还原
