摘要

本次课题是设计一个18.5m3的尾气缓冲罐，主要包括结构设计和焊接工艺设计两大方面。

在结构设计方面：首先根据设计条件确定设计文件，设计文件包括设计压力、设计温度、介质性质、材料的种类及焊接接头系数等，其次对零部件进行设计。零部件的设计包括筒体设计、封头设计、开孔补强、法兰、人孔、支座和吊耳的计算和选择。在完成以上设计后根据设计数据完成总图和零件图的绘制。

在制造工艺方面：首先根据图纸完成制造工5艺流程设计，其次根据流程重点对筒体、封头的制造和无损检测、水压试验等重点工序进行阐述，最后对筒体和封头纵环缝焊接工艺进行设计，并采用设计的焊接工艺进行试验、对焊接试样进行了力学性能分析。试验结果满足使用要求，证明焊接工艺是合理的，能够成功实现产品的制造。

这次设计的主要意义在于锻炼了自己独立分析问题、解决问题的能力。培养了查阅资料、工作细致、认真负责、独立思考、自主创新的能力。并通过此课题的研究来进一步增强低理论知识的掌握以及研究类似问题的能力，为今后的工作打下基础。

《化工设备机械基础》是化工工艺类专业一门综合性的机械类技术基础课，本设计是以掌握中、低压压力容器的设计为目的，以一系列技术法规、设计规定、材料和零部件标准为依托，讲解材料、机械、结构方面的基础知识。其任务是使学生掌握相关的基本理论、基本知识以及设计的基本方法，为从事化工设备机械的设计、使用、管理和维护打下基础。

完成一项相关设计是设计学习的主要目的，也是化工工艺类学生十分重要的教学环节之一。目的是为了使学生进一步加深并综合运用课本基本理论，训练和掌握典型化工设备机械设计的基本技能。

“化工设备机械基础设计”包括设计计算和机械制图。通过将“化工设备机械基础”与“化工原理设计设计”有机地结合起来，形成了“化工单元过程及设备设计”综合实践教学体系，提高学生查阅资料、理论计算、工程制图、数据处理、化工设备设计说明书写作等方面的能力。

本设计的主要内容：参照化工设备机械基础的化工容器设计，本设备按GB150-1998《钢制压力容器》，TSG R0004-2009《固定式压力容器安全技术监察规程》等标准法规进行设计、计算、校核。设计参数、接管方位和几何尺寸按工艺条件确定。焊接按JB/T4709-2009《压力容器焊接规程》。综合考虑各种因素，变压吸附尾气罐的结构设计选择适用合理、经济的结构形式，同时满足制造、检修、装配、等要求；而强度计算的内容包括尾气缓冲罐的材料，确定主要结构尺寸，满足强度、刚度和稳定性等要求，根据设计压力确定壁厚，使尾气缓冲罐有足够的腐蚀裕度，该设计分析包括内压薄壁圆筒与封头的强度设计、容器零部件的设计，包括法兰连接、容器支座、人孔的设计。最终确定尾气缓冲罐的标准。从而使设计结果达到最优化组合。

ABSTRACT

ABSTRACT

The project is to design a tail gas buffer 18.5m3, including structural design and welding technology in two areas.

In structural design: First, determine the design documents under design conditions, design documents, including the design pressure and design temperature, medium properties, the types of materials and welded joints coefficient, followed by the design of the parts.The design components include cylinder design, head design, reinforcement, flanges, manholes, supports and lug the calculation and choice. After the completion of the above design data according to the design plans and parts to complete the total mapping.

In the manufacturing process: First, complete the manufacturing process based on design drawings, then according to the process focuses on the cylinder, head of manufacturing and non-destructive testing, pressure testing and other key processes were described, and finally head of the cylinder and the longitudinal girth welding process design and welding process used to test the design on the mechanical properties of welded samples were analyzed. The results meet the requirement to prove that welding is reasonable to successful products.

The main significance of this design exercise its own independent analysis of issues, problem-solving abilities. Develop a data access, work is meticulous, conscientious and responsible, independent thinking, the ability of independent innovation. This topic through research to further enhance the low theoretical knowledge and research similar problems to master the ability to lay the foundation for future work.

"Chemical equipment machinery foundation" is a comprehensive chemical process engineering machinery technology basic course, this design is based on mastering the medium and low pressure vessel design for the purpose, with a series of technical regulations, and rules for design, materials and parts standard as the backing, explain the basics of materials, machinery, structure. Its mission is to enable students to master relevant basic theories, basic knowledge and the basic design methods, is engaged in chemical equipment mechanical design, use, management and maintenance.

Complete a related design is the main purpose of the study design, is also a chemical process class students one of very important teaching link. The purpose is to make students further deepen and by using the basic theory of textbooks, training and master the basic skills of typical chemical equipment mechanical design.
