1、南华大学机i械工程学院φ800气提塔设计摘要：填料塔是以塔内的填料作为气液两相间接触构件的传质设备。填料塔的塔身是一直立式圆筒，底部装有填料支承板，填料以乱堆或整砌的方式放置在支承板上。填料的上方安装填料压板，以防被上升气流吹动。液体从塔顶经液体分布器喷淋到填料上，并沿填料表面流下。气体从塔底送入，经气体分布装置（小直径塔一般不设气体分布装置）分布后，与液体呈逆流连续通过填料层的空隙，在填料表面上，气液两相密切接触进行传质。填料塔属于连续接触式气液传质设备，两相组成沿塔高连续变化，在正常操作状态下，气相为连续相，液相为分散相。强度校核部分是本次汽提塔设计中的重点，也是难点，他分
2、为圆筒厚度校核，封头厚度校核，圆筒轴向力校核和圆筒稳定校核，塔设备压力试验时的应力校核，裙座轴向应力校核，基础环和地脚螺栓设计及校核，筋板设计及校核，盖板设计及校核。设计中个部分校核都必须合格，从而保障设计的科学合理性。关键词：填料塔；圆筒、封头；试验；校核Designofφ800stripperi南华大学机i械i工程学院Abstract：Towerpackingtowerpackingisbasedongas-liquidtwo-phasecontactasacomponentofmasstransferequipment.Thetowerisapackedtowerhasv
