精馏塔装置结构设计(含CAD)(论文说明书12000字,CAD图6张)
摘要
精馏塔设备是化工行业生产过程中用于精馏单元操作的重要设备之一，其性能的优良对生产成品的产量、质量、消耗定额、三废处理等各方面有重大的影响。精馏塔主要有两种，分别为板式塔和填料塔，其中板式塔内件以塔板作为两相接触的基本构件。塔板的类型较多，主要有浮阀塔板、喷射型塔板、旋流塔板等多种。本课题在查阅大量文献资料基础上，根据GB150-2011《压力容器》、GB151-1999《管壳式换热器》等相关标准对精馏塔装置结构进行结构设计，并完成了精馏塔装置主要受压元件设计计算书。通过绘制精馏塔装置结构装配图、结构部件图及零件图并使用SW6-2011软件校核其主要受压元件(钢制卧式容器、换热器等)强度，结果表明该精馏塔装置各部分元件均符合精馏塔相关国标中的各项要求，设计合理。

Distillation column device structure design
Abstract
Distillation column equipment is one of the important equipments for the distillation unit operations in the chemical industry production process , and whether its performance good or bad has a significant impact on the finished product yield , quality, consumption of fixed ,and waste treatment , and other aspects of the production . There are two kinds of distillation columns , including plate column and packed column , in the former one , the plate internals as the fundamental construction member for the two components in contact . There are many types of trays , such as valve trays , jet trays, cyclone trays and other types . This topic requires to access to a large literature basis, according to GB150-2011 《pressure vessel》, GB151-1999 《shell and tube heat exchanger》 and other relevant standards to design the structure of a distillation column and complete the calculations of the weighted elements in the column. By drawing the unit structure assembly drawings, structural components and parts diagram of distillation column and using the SW6-2011 software to check the intensity of the main weighted components ( steel horizontal vessels, heat exchangers , etc. ) , the results show that each element of the distillation column complies with the requirements of national standards of distillation column in reasonable design .
