| 摘要：此次设计回流塔的介质为铜氨液、再生气，塔的设计温度为100℃，设计压力为0.18MPa，塔径1400mm，塔高10.48m，填料塔，填料段：1。塔设备是生产过程中一种重要的单元操作设备，它广泛应用于化工、炼油、医药、食品及环境保护等工业部门。本铜氨液、再生气回流塔的作用是利用铜氨液对再生气中所含的少量一氧化碳和二氧化碳进行脱洗。首先考虑到工艺条件等因素，塔体的材料选用了Q345R。其次对塔进行了强度和稳定性校核，计算了质量载荷，塔的自振周期、地震载荷与地震弯矩、风载荷与风弯矩。进行了圆筒轴向应力校核和裙座轴向应力校核。通过计算得出强度和稳定性都符合要求。然后通过比较不同的元件，分别对吊柱、吊耳、填料、设备接管、法兰、平台及扶梯进行了设计选择。最后利用Fluent软件对该回流塔进行上段液体流动分析，检验回流塔上段液体流动是否满足均匀分布要求。8867 关键词：填料塔；铜氨液；再生气；压力容器；Fluent Design of Cuprammonia and Resurgent gases Reflux Column Abstract：The media of this design of cuprammonia and resurgent gases column is cuprammonia and resurgent gases, and it’s design temperature is 100℃, design pressure is 0.18MPa.The diameter of column is 1400mm,and height is 11.48m,which is packing layer and has 1 trays. Column is an important process equipment, which is widely used in petrochemical, pharmacy, food, environment protection and so on. The cuprammonia and resurgent gases column is to use cuprammonia wash off a small amount of carbon monoxide and carbon dioxide contained in the regeneration gas. Based on process conditions,Q345R was chosen as column material. Stiffening was made at open pore region and stiffening rings was chosen. The strength and the stability of the column were checked including calculating mass loads, self-vibrations cycles, earthquake loads, earthquake moments, wind loads, wind moments. The axial stresses in cylindrical shell and skirt support were checked. The strength and the stability of the column were eligible. And by comparing different components, davits, sag, trays, tubes, flanges, flats and ladders were designed and chosen. Finally,Fluent6.3.26 which is used to analysis has been used for check the liquid.
