铜氨液、再生气回流塔的设计_毕业设计说明书铜氨液、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10.48m关键词：填料塔；铜氨液；再生气；压力容器；FluentDesign of Cuprammonia and Resurgent gases Reflux ColumnAbstract：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.
