1、 上海应用技术学院 机械工程学院 毕业设计（论文） 题目 铜氨液、再生气回流塔的设计 学生姓名 徐骏 专 业 过程装备与控制工程 学 号 0910221130 班 级 09102211 指导教师 朱柳娟 职 称 讲师 2013 年 6 月铜氨液、再生气回流塔的设计 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 11.25m，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
2、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。 关键词：填料塔；铜氨液；再生气；压力容器； Fluent Design of Cuprammonia and Resurgent gases Reflux Co
