汽提器塔盘用于流化催化裂化装置的汽提段 ,待生催化剂与汽提流体接触除去催化剂中的烃。①上段收集催化剂 ;②下段垂直置于上段下方 ,在塔盘边缘向下级垂直塔盘卸催化剂 ;③一种表面倾斜的塔盘 ,环绕置于上下级塔盘之间 ,与塔盘表面的倾斜角度为 1 0～ 80°,可使催化剂径向运 The stripper tray is used in the stripping section of the fluid catalytic cracking unit and the spent catalyst contacts the stripping fluid to remove the hydrocarbons from the catalyst. (1) the upper section collects the catalyst; (2) the lower section is placed vertically below the upper section and the catalyst is removed from the vertical tray at the lower edge of the tray; (3) a slanting tray with a surface inclined between the upper tray and the lower tray Angle of 10 ~ 80 °, the catalyst can be transported radially
