摘要
本课题研究的目的主要部分是针对给定的筛板塔的设计要求，通过查阅资料、分析设计条件，根据一些基本计算来确定筛板塔的结构及工艺。
本次设计时要考虑实际要求，遵循塔设备的设计原则，要经历需求分析、目标界定、总体结构设计、零部件结构设计、参数设计和设计实施这几个过程。在这个不断决策的过程中，应当结合多方面考虑，使方案更加合理与准确，最终确定的设计方案就越理想。设备设计最终必须综合平衡产品性能、成本和环境这三个方面的要求。通过分析筛板塔的设计条件，确定零部件的设计加工步骤。完成对筛板塔的塔体、内件、群座、封头、筒体及附件等部件的材料选择、壁厚计算和强度校核。绘制符合要求的筛板塔的图纸，给出相关的技术要求。
在筛板塔的结构设计过程中，要参考相关的标准要求进行设计，使设计能够符合相关标准。同时要使设计的结构要求满足生产的需要，达到安全生产的要求。
