1、 I 甲醇水分离塔设计甲醇水分离塔设计 摘要摘要 筛板塔是传质过程常用的塔设备，它的主要优点有： 结构比浮阀塔 更简单，易于加工，造价约为泡罩塔的 60，为浮阀塔的 80左右。 处理 能力大， 比同塔径的泡罩塔可增加 1015。 塔板效率高， 比泡罩塔高 15 左右。 压降较低，每板压力比泡罩塔约低 30左右。虽然筛板塔有： 塔 板安装的水平度要求较高，否则气液接触不匀。 操作弹性较小(约 23)。 小孔筛板容易堵塞等缺点。但它由于具有前述的一些优点，因而在化工，石油， 能源等行业的应用中仍处于板式塔应用的主导地位。本次论文以介质的性质、温 度和压强，以及公称直径和当地自然环境为设计条件，综合

2、考虑各方面的因素选 定板式筛板塔，具体步骤主要包括壳体、封头壁厚的设计与较核，基础环板，裙 座等零部件的设计， 同时结合所选定的材料和工作环境制定相应的焊接工艺和制 作、组装和加工工艺。 关键词关键词 筛板塔；塔盘；降液管 II Abstract The sieve-plate column is commonly used in mass transfer tower equipment, its main advantages: structural valve tower more than a simple, easy processing, and cost about 60% of

3、 bubble tower, tower float valve for about 80% . processing capacity, than the diameter of the blister with tower 10 15% increase. tray efficiency higher than that Blister tower about 15% higher. lower pressure drop per plate bubble tower pressure than about 30%. Although the sieve-plate column are:

4、 tray installation require a higher degree level, or gas-liquid contact with uneven. Operating flexibility small (about 2 3). small plate, such as easy to plug the shortcomings. But it is because of some of the advantages mentioned above, which in the chemical, petroleum, energy and other industries

5、 are still in the application of the application tray column dominance. The thesis of the nature of media, temperature and pressure, as well as the nominal diameter for the design of the natural environment and local conditions, concrete steps to include the shell, head of design and wall thickness

6、more nuclear, based on the Central board, and other parts of the skirt design, combined with selected materials and the working environment to develop the corresponding welding technology and production, assembly and processing technology.
