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 Design of φ 800 stripperAbstract:Tower packing tower packing is based on gas-liquid two-phase contact as a component of mass transfer equipment. The tower is a packed tower has vertical cylinder, equipped with a filler at the bottom of bearing plates, fill the entire block to huddle or placed in the way of support on the board. Fill the top of the filler plate is installed to prevent air blowing was increased. Liquid from the top of the tower by spraying liquid distributor to fill, and down along the filler surface. Into the gas from the bottom, with gas distribution equipment (small-diameter tower generally no gas distribution device) distribution, and fluid was counter-current continuous layer through the gap filler in the filler surface, the gas-liquid two-phase mass transfer in close contact to .Packed column is continuous-contact gas-liquid mass transfer equipment, two-phase composition changes in a row along the tower, in the normal operating mode, the gas for the continuous phase, liquid ph...
