| 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. |
