固体氯化钡酸化工段工艺设计2

（二〇一二年一月本科毕业设计说明书学校代码：10128学号：题目：固体氯化钡酸化工段工艺设计学生姓名：李敏学院：化工学院系别：化学工程系专业：化学工程与工艺班级：指导教师：李铁云教授内蒙古工业大学本科毕业设计说明书摘要我国冶金和金属加工行业每年有大量酸洗废液排放，该酸洗废液是冶金和金属加工行业进行钢铁表面除锈时氧化铁溶于盐酸产生的废液，其主要含有氯化亚铁和少量游离酸。用该酸洗废液代替盐酸直接浸取毒重石可制备氯化钡，不仅可以降低其生产成本，同时也为酸洗废液的综合利用提供了一条较好的出路。氯化钡是重要的化工原料，是制备其它钡盐和其它材料的主要中间原料，主要应用于制造钡盐、鞣革、颜料、染料、化学试剂、羊毛染色助剂、金属淬火加工、人造丝的消光剂、锅炉水的处理、防止陶瓷制品褪色、制取金属钡及钡炸药、农药、化工等领域。我国氯化钡的生产能力为10万吨左右，氯化钡的生产厂家主要集中天津、河北、河南、重庆、四川、山东、山西、浙江、江苏。我国是主要的出口国，具有垄断世界市场的能力，产品主要销往国内和东南亚国家。本文设计了生产固体氯化钡的酸化工段，利用的方法是以毒重石为原料，采取盐酸酸化、烧碱中和的工艺。设计过程中先进行原料以及生产方案的选择，之后进行物料衡算和热量衡算；再根据物料衡算的结果以及工艺流程画出物料流程图；接着绘制工艺管道及仪表流程图；根据设备选型的结果和流程图绘出设备布置图和立面图；最后完成首页图和设备一览表。关键词：氯化钡；毒重石；物料衡算内蒙古工业大学本科毕业设计说明书AbstractBariumchloridewasanimportantchemicalrawmaterials，thepreparationofothersisthemainBariumsaltandotherrawmaterialsandintermediate，mainlyusedinmanufacturingBariumsalt，tanning，pigment，dyestuff，chemicalreagent，wooldyeingauxiliaries，metalprocessing，rayonquenchingthewave-rayagents，boilerwatertreatment，preventceramicsfade，makingmetalbariumandbariumexplosives，pesticides，chemicalindustry，etc．BariumchlorideproductioncapacityinChinais10milliontons，BariumchloridemanufacturermainlyconcentratedinTianjin，Hebei，Henan，Chongqing，Sichuan，Shandong，Shanxi，Zhejiang，Jiangsu．Ourcountryisthemainexportersintheworldmarket，theability，themonopolyproductsaremainlysoldtodomesticandsoutheastAsiancountries.ThispaperdesignstheproductionofsolidBariumchloride，usingtheacidificationsectionmethodbasedonpoisonforrawmaterial，adoptsthestone，causticsodaacidneutralizationprocess．Thedesignprocessforrawmaterialandproductionplanselection，aftermaterialandheatbalance，Accordingtotheresultsofthematerialandprocessflowchart，drawmaterials，Thenrenderingprocesspipingandflowchartmeters，Accordingtotheresultsoftheequipmentselectionandflowchartdrawingequipmentlayoutandelevation．Keywords：Bariumchloride；Poisonstone；Material内蒙古工业大学本科毕业设计说明书目录引言.......................................................................................................................................1第1章总论.........................................................................................................................21.1说明书.....................................................................................................................21.1.1设计依据.......................................................................................................21.1.2设计指导思想...............................................................................................21.1.3设计范围.......................................................................................................21.1.4建设规模及产品方案...................................................................................21.1.5主要原材料的规格及其消耗量和来源.......................................................31.1.6生产方法及全厂总流程...............................................................................31.2厂址概况.................................................................................................................41.3工程水文地质条件和气象资料..............................................错误!未定义书签。第2章化工工艺及系统.....................................................................................................62.1概述.........................................................................................................................62.1.1装置设计规模，装置组成与各工序名称...................................................62.1.2生产方法、流程特点...................................................................................62.1.3生产制度.......................................................................................................62.2原材料及产品的技术规格.....................................................................................62.2.1原材料的技术规格.......................................................................................62.2.2中间产品的技术规格...................................................................................62.3生产流程简述.........................................................................................................7第3章氯化钡酸化工段物热衡算.....................................................................................83.1氯化钡酸化工段物料衡算.....................................................................................83.1.1原材料...........................................................................................................8内蒙古工业大学本科毕业设计说明书3.1.2酸化...............................................................................................................83.1.3中和.............................................................................................................163.1.4过滤.............................................................................................................193.1.5吸收.............................................................................................................213.2氯化钡酸化工段热量衡算...................................................................................223.2.1酸化.............................................................................................................223.2.2中和..
