摘　　要：对垂直筛板帽罩内装催化剂构成的新型塔构件进行了实验研究。考察了板孔动能因子、催化剂藏量、床层空隙率对塔构件压降、罩体喷出量以及液泛和漏液速度的影响。结果表明:压降随板孔动能因子和催化剂藏量的增加而增大,随床层空隙率的增加而减小;罩体喷出液体量随着板孔动能因子的增加先增大后减小,随床层空隙率的增加而增大,随催化剂藏量的增加而减小;漏液速度随液体流量、藏量的增加而增大,随空隙率增大而减少;液泛速度随床层空隙率、液体流量的增大而减小,随藏量增加而增大。新型塔构件流体力学性能良好。The new column internals which were composed of the vertical sieve tray caps filled with catalyst were studied. The experiment investigated the influence of kinetic energy factor in plate holes, catalyst inventory, bed porosity on the pressure drop of column internals, cap unit ejection quantity, and flooding and liquid leakage velocity. The results show that the pressure drop rises with the increase of kinetic energy factor in plate hole and catalyst inventory, and decreases with the increase of bed porosity. Cap unit ejection quantity rises first and then decreases with the increase of kinetic energy factor in plate holes, rises with the increase of bed porosity, and decreases with the increase of catalyst inventory. Liquid leakage velocity rises with the increase of the liquid flow and inventory and decreases with the increase of porosity. Flooding velocity decreases with the increase of bed porosity and liquid flow, and rises with the increase of the inventory. All of the above indicate that the hydrodynamics performance of new type column internals is excellent.
