Abstract: Super float valve（SFV）tray is a new type of trays developed by China University of Petroleum. SFV tray was designed with many innovation and optimization for valve structures combining the advantages of guide rectangular valve tray and micro V-grid fixed valve. The hydraulic and mass transfer performances of SFV were investigated with an air-water-oxygen system in a stainless steel column of 1200 mm in comparison with the traditional F1 tray. Experimental results showed that SFV has pressure drop lowered by 10%—20%，weeping rate lowered by 20%—30%，entrainment lowered by 20% and mass transfer efficiency increased by 10%—20% as compared with F1. The industrial application showed that the high performance SFV tray could be used to the design and restoration of columns.

摘要： SFV全通导向浮阀塔板为中国石油大学开发的新型塔板，其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，在结构上进行了多方面的创新和优化。采用空气-富氧水体系，在1200 mm不锈钢塔内，对SFV全通导向浮阀塔板的流体力学与传质性能进行了测试。结果表明，与F1型浮阀塔板相比，塔板压降可降低10%～30%，漏液率降低10%～30%，雾沫夹带降低10%～20%，传质效率可提高10%～20%。工业应用表明，该种塔板综合性能优异，可用于石油化工等行业的老塔改造与新塔设计。
