摘　　要：研究了新型立体传质塔板(CTST)的气相提升能力,提出了相对提升量的概念。得出了新型立体传质塔板的气相提升能力与板上清液层高度、板孔动能因子以及罩体底隙的关系。研究了单罩以及多罩组合情况下气相提升能力的变化情况,对几种立体喷射型塔板的气相提升能力进行了对比。结果表明,在相同条件下新型立体传质塔板的气相提升能力明显高于其他几种塔板。Gas elevating capability of combined trapezoid spray tray(CTST)was studied,and the conception of relative elevating amount was put forward for the first time. The relationship between gas elevating capability of CTST and clear liquid height on the plate, F-factor based on tray hole, clearance between the cap and the plate was concluded. In single cap and combined several caps, the change of gas elevating capability was also studied. By comparing the capability of several spatial spray trays, it was founded ...
