摘　　要：分析了梯形立体喷射(CTST)塔板的结构与性能,通过CTST塔板对环氧乙烷(EO)精制塔改造的实例,采用计算机模拟,对CTST塔板的全塔效率及水力学性能进行了核算。结果表明,CTST塔板与F1浮阀塔板相比,全塔效率高1 5%,生产能力高80%以上。改造后的环氧乙烷精制塔部分空塔动能因子超过3 0kg1/2/(s·m1/2)。This paper introduces the structure and operational performance of the combined trapezoid spray tray(CTST).CTST has many advantages over float valve tray,for example,the overall column efficiency increases by 1 5% ,the production capacity increases by 80%～100%,the range of operation was 2 times as much and the column pressure drop decreases by 20%～30%,etc.In the technical transformation of the ethylene oxide treating column,float trays were replaced by CTST trays.As a result,the production capacity increased by 80%,with F T partially in excess of 3 0 kg 1/2 /(s·m 1/2 ).
