| 摘要：塔设备是化工、石油化工和炼油、医药、环境保护等工业部门的一种重要的单元操作设备。塔设备的设计包括两个部分：工艺设计和机械设计。机械设计部分要解决的问题除了确定塔设备的各个细节结构外，更重要的就是要做各种校核工作，以保证设计完成的塔设备不仅能够正常运转，而且必须符合国家安全生产的标准。其校核内容主要包括：质量载荷、地震载荷、风载荷等，好包括强度及稳定性校核。图纸包括零件图和一张装配图。完成筛板水洗塔成套装置肢体部分结构设计，结构设计是指压力容器设计部分，即计算塔的壁厚，封头的结构及尺寸，水洗塔的附件设计，接管设计等内容。辅助装置及附件结构设计：接管的设计与相关法兰的选用、除尘器、人孔及其附件的设计。全塔校核包括塔体与封头壁厚的确定、塔设备质量载荷及自振周期的计算、地震载荷与地震弯矩、风载荷与风弯矩计算、圆筒轴向应力和圆筒稳定性校核、塔设备压力试验时的应力和裙座轴向应力的校核。9841 关键词：筛板塔；塔盘；塔板性能；结构设计 Design of Washing Tower Abstract：Tower equipment is chemical, petrochemical and refining, pharmaceutical, environmental protection, and other industrial department is a kind of important unit operation, The design of the tower equipment consists of problem to solve, in addition to determine the details of the tower equipment structure outside, more important is to do all kinds of work check, in order to ensure that the design of tower equipment can not only finish the normal operation, and must comply with the national safety production standards. Check the content mainly includes: quality load, earthquake loads, the wind loading, etc, also including the strength and stability are checked. Drawings including a assembly drawing and drawing. Complete body of complete set of equipment of the column plate structure design, structure design is the design of pressure vessels parts, namely calculation of the tower wall thickness, the head of the structure and size, design of the column accessories, and took over the design. Auxiliary equipment and accessories structure design: take over the design and the related flange of selecting, except the foaming machine, manhole and its annex design. The tower check: including tower body and the head of the thickness is sure, tower equipment quality load and natural vibration period of calculation, earthquake loads and seismic moment, the wind load and the wind bending moment calculation, cylinder axial stress and cylinder stability checking, tower pressure test equipment of stress and axial stress of skirt a check. Key words: sieve-tray column; structure design; screen panel tower；Plate properties. 目 录 摘要 I ABSTRACT I 1 绪论 1 1.1 课题介绍 1 1.2 课题研究的意义 1 1.2.1 发展筛板塔的意义 1 1.2.2 筛板塔应用的意义 2 1.3 国内外水洗塔设计的研究进展与主要成果 2 1.3.1 国内外水洗塔的研究进展与主要成果 2 1.3.2筛板塔的结构特点和工作过程 3 1.3.3筛板塔在工业中的应用 4 1.3.4 筛板塔的复合性能 4 1.3.5 课题研究的内容 5 1.3.6 难点分析及创新点 5 2 水洗塔的结构设计 6 2.1 材料选取 6 2.1.1压力容器用材的基本要求 6 2.1.3 裙座和接管材料的选择 7 2.1.4 整体塔高的确定 7 2.2 结构设计 7 2.2.1 筒体和封头的厚度计算 7 (责任编辑：qin) |
