DN1100斜孔式精馏塔设计含11张CAD图+说明书
DN1100斜孔式精馏塔设计 摘要 本次设计的是DN1100斜孔式精馏塔,其中DN1100表示的是该塔的塔内径。斜孔式精馏塔属于板式塔的一种,其塔盘采用的是斜孔塔盘,斜孔塔充分地结合了筛板塔和浮阀塔的优点。斜孔塔盘是属于喷射型塔盘,近似于筛孔塔板,流动状态比筛孔塔板合理,性能比筛孔塔板优越。不过也有类似筛孔塔板的缺点,如有设计方法和使用技巧不正确时,容易被误会为弹性小,不好操作而得不到重视。其与浮阀塔盘相比,弹性不如浮阀塔盘,但处理量大大超过浮阀塔盘。斜孔塔盘优缺点并存,本设计的目的就是要尽量放大其具备的优点,再进一步缩小其缺点,提高塔盘的处理效率,解决斜孔容易堵塞以及设计使用方法复杂等难题,让其得到工人们的认可,并将其推广发扬。整个设计过程,我通过塔体载荷,塔体的强度等不同方面的数据计算来设计斜孔塔盘的最优数值,根据计算得出的数值来进一步确定塔盘的最佳摆放位置与最优开孔方式。为了使斜孔塔盘能发挥其最大的功效,在选材方面也要进行慎重考虑。最后一步就是塔设备安装与运输计划的制定,以及防腐工作计划的确定。除此之外,对于斜孔塔盘的加工工艺过程也需有详细的加工计划。 关键词:斜孔塔盘;精馏塔;喷射型;板式塔;DN1100;设计 ABSTRACT I desig
