DN1800浮阀塔装配图

摘要
塔设备是化工、炼油、医药等工业中广泛使用的重要生产设备。本设计为浮阀塔，浮阀塔在操作弹性、塔板效率、压降、生产能力以及设备造价等方面都比较优越，是化工生产中主要的传质设备之一。在计算说明部分，先确定设计方案，然后开始对塔的强度及稳进行计算。主要包括筒体和裙座的厚度计算，塔器的质量计算，塔的自振周期计算，地震载荷和地震弯矩的计算及风载荷和风弯矩计算；圆筒应力校核，裙座稳定性校核，还对基础环、地脚螺栓、筋板、盖板进行了设计计算，最后对裙座和塔壳的焊缝进行验算。接下来的部分对人孔和检查孔、再沸器入口、釜液进再沸器入口、塔顶蒸汽出口、回流液入口、进料口、釜液出料口等进行了补强计算。上述各项设计计算验算合格，强度和稳定性计算校核符合要求。
该塔适用于沉阳地区，抗地震烈度7级，地震分组为第一组，场地土类别为二类。工作压力1.9MPa，工作温度80℃。主要介质为丙烯、丙烷、丁烷等易燃物质。该塔为Ⅲ类压力容器，焊接接头采用双面焊对接接头，100%无损检测。塔体总高32.5m，塔体直径1800mm，塔壳壁厚20mm，筒体采用Q345R材料，裙座采用Q235A材料。选用50层双溢流塔盘，塔盘间距600mm。塔器最大质量为116701.3kg，最大吊装质量为94328kg，全容积97.477m3。

Tower equipment is chemical, oil refining, pharmaceutical and other important production equipment widely used in the industry. This design is the float valve tower, the float valve tower in the operation flexibility, the tower plate efficiency, the pressure drop, the production capacity and the equipment cost and so on aspects are comparatively superior, is chemical production in one of the main mass transfer equipment.In the calculation, the design scheme is first determined, and then the strength and the stability of the tower are calculated.. Mainly includes the drum body and skirt thickness calculation, calculate the quality of tower, tower of self vibration period calculation, calculation of earthquake load and bending moment calculation and wind load and wind moment; cylinder to check, skirt stability check, the foundation ring, anchor bolts, stiffened plate, cover plate to the design calculation, checking the final weld on the skirt and tower shell. The next section of manholes and manhole, reboiler inlet kettle liquid into the reboiler inlet, steam outlet at the top of the tower, reflux liquid inlet, inlet, kettle liquid out of the discharge hole for the reinforcement calculation. The calculation of the above calculation is qualified, the strength and the stability of the calculation are calculated and checked..
The tower is suitable for the Shenyang area, the earthquake intensity of 7 earthquake, the earthquake grouped for the first group, the ground soil category is two kind of. Working pressure 1.9MPa, working temperature 80. The main medium is propylene, propane, and other flammable substances.. The tower is a type III pressure vessel, welded joints using double-sided butt welded joints, 100% non-destructive testing. The tower height of 32.5m, tower diameter 1800mm, tower shell wall thickness of 20mm tube made of Q345R material, the skirt made of Q235A material. The 50 layer double overflow tray, tray spacing 600mm. The maximum mass of the tower is 116701.3kg, the maximum hoisting quality is 94328kg, the full volume is 97.477m3.
