硫酸生产毕业设计.doc

武汉工程大学本科毕业设计 PAGE 42 摘 要 硫酸生产工艺主要由五部分组成，包括二氧化硫气体的制取，炉气的净化，二氧化硫气体的转化，三氧化硫气体的吸收以及尾气的处理。主要包括工艺流程的选定，工艺过程计算，主要设备工艺计算及选型，以及绘制 部分设备的平面布置。本设计采用二塔二电流程，以年产11万吨硫酸车间净化工段工艺设计，设计中对主要工序进了物料衡算，热量衡算，并以此绘制物料平衡表和热量平衡表。然后以净化工段为重点，对相关设备进行了计算。 关键词：硫酸；二塔二电；物料衡算；热量衡算；工艺设计  Abstract Sulfuric acid production process is mainly composed of five parts, including the preparation of sulfur dioxide gas, the furnace gas purification , the transformation of sulfur dioxide gas, the absorption of sulfur trioxide gas and the treatment of exhaust gas processes. The design mainly describes about the process of sulfuric acid production with the annual production capacity of 110,000 tons, including the flow process design, the calculation and selection of the main equipment, the layout of some equipment. Used pyrite as the raw material in the design. The design mainly calculated the mass balance and heat balance，and drew material balance table and heat balance in mainly production process. And then,use the depuration segment as the emphasis ,calculated The relevant Model Selection of the Related devices.Finally, the process description, security memorandum, memorandum of technical risk, the proposal of environmental protection and management were complete. Key words：Sulfuric acid;two towers and two Electric precipitators; mass balance;heat balance 目 录 TOC \o 1-3 \h \u HYPERLINK \l _Toc15599 第一章 文献综述 PAGEREF _Toc15599 1 HYPERLINK \l _Toc25839 1.1硫酸的性质 PAGEREF _Toc25839 1 HYPERLINK \l _Toc28620 1.1.1硫酸的物理性质 PAGEREF _Toc28620 1 HYPERLINK \l _Toc26057 1.1.2硫酸的化学性质 PAGEREF _Toc26057 1 HYPERLINK \l _Toc8832 1.2硫酸的生产方法 PAGEREF _Toc8832 2 HYPERLINK \l _Toc10496 1.2.1硝化法制造硫酸 PAGEREF _Toc10496 3 HYPERLINK \l _Toc21891 1.2.2接触法制造硫酸 PAGEREF _Toc21891 3 HYPERLINK \l _Toc28197 1.3硫酸的安全生产 PAGEREF _Toc28197 4 HYPERLINK \l _Toc28464 1.3.1硫酸工业中催化剂的重要作用 PAGEREF _Toc28464 4 HYPERLINK \l _Toc23279 1.3.2硫酸生产中可能存在的危害 PAGEREF _Toc23279 5 HYPERLINK \l _Toc7171 1.3.3我国硫酸工业技术概况 PAGEREF _Toc7171 6
