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，还包括强度及稳定性校核。图纸包括一张装配图和零件图。

Design of Process Water Hydrogen Degassing Tower
Abstract：Tower equipment is chemical, petrochemical and refining, pharmaceutical, environmental protection, and other industrial department is a kind of important unit operation equipment. The design of the tower equipment consists of two parts: the process design and mechanical design. Mechanical design part 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 the 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 Hydrogen plant process water degassing tower 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, etc.
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：same wall thickness；packed tower；Ⅰ class pressure vessel
