1、常压塔设计论文常减压装置中常压塔设计摘要塔设备是化工,石油化工和炼油生产屮最重要的设备之一。塔设备是大部分机械专业理论学习的重点设备,也是化工厂中常见的设备。随着石汕,化工生产的迅速发展,塔设备在石油化工生产中投入所占的比例越来越大,占到大概百分之五十的比例。塔设备的性能,整个装置的产品产量,质量,生产能力和消耗定额,以及三废处理和环境保护方面都有重要意义。因此选择沥青装置常压塔设计。本文是以专业知识为基础,对六十万吨每年氧化沥青装置常压塔进行的设计计算,该塔可以在常压,一百五十摄氏度温度下工作。该塔设备为浮阀塔,优点是生产能力高,操作弹性大
2、,气液流动阻力较小,塔板效率较高,但浮阀装卸清洗较W难,造价高,总体来讲综合性能较好,可以在工业上得到普遍应用。塔设备的设计具有很强的综合性,尤其在塔的高度较高时,要注意考虑高振型以及横风向风振对塔设备的影响。当前板式塔应该以处理能力为第一目标,传质效率为第二目标,开发的重点集中在降液管结构改进,塔板空间合理利用,气液分散结构优化以及降低成本等方面的改进。关键词:常压塔;沥青装置;浮阀DesignofatmospherictowerTowerequipmentinchemical,petrochemicalandoilrefiningprod
