摘要: 基于火力发电厂烟气脱硫工程化项目的需要 ,提出了一种同时具备大孔径和高开孔率条件、由大孔筛板和波纹板填料及其附件构成的复合塔板 ,研究了孔径和开孔率对于该复合塔板流体力学性能的影响 .结果表明 :与其他的塔板相比 ,该塔板在同样的操作条件下压降更低 ,通量更大.
Abstract: As a large equipment used in flue gas desulfuration,Plural Tray,which operates in the spray regime and consists of large-holed sieve tray and structured packing,has been developed.Hydrodynamics of such new sieve tray is studied in this paper.The experiments are accomplished in a cold model column with diameter of 400mm.The effect of hole diameter and free area of Plural Tray on the hydrodynamic properties is studied.The larger the hole diameter is,the more the wet tray pressure drop is;the more the free area is,the worse the operating flexibility is.As a result,Plural Tray has the characteristics of lower resistence,little entrainment and big upper limit velocity of operation.
