毕业设计学生姓名：赵三明学号：100609235学院：材料科学与工程学院专业：冶金工程题目：废轮胎裂解新工艺方案的设备设计指导教师：代娟评阅教师：孙兰2014年06月毕业论文中文摘要本设计最大的特点，是利用了钢铁厂的废气；提出了一种高效、环保的具有很大吸引力的废轮胎的回收的工艺。论文主要针对这种绿色的设计理念，设计了相应的废旧轮胎裂解设备。包括预热仓，裂解仓，热风炉。与现存的以电能供热的设备相比，最大的优点和竞争力主要体现在热风炉上。本工艺摒弃了现存利用电能的设备，将钢铁厂的废弃物和废旧轮胎的裂解联系在一起，进行能量回收利用，减小了能耗，降低了成本，具有很好的前景。论文研究和设计了氮气气氛下废旧轮胎的裂解工艺路线.并设计了预热炉和加热炉，改良了废氮气的回收与利用流程。详细设计了裂解100千克废旧轮胎具体工艺过程.其预热温度设定为260℃，裂解温度设定为500℃。同时，本文充分利用氮气的惰性保护，选择了具有受热均匀的立式裂解塔，使裂解更加充分，能量得到更加充分的利用。关键词废旧轮胎热裂解裂解设备毕业论文外文摘要TitleNewequipmentdesignprocessschemeofwastetirepyrolysisAbstractThebiggestfeatureofthisdesignistheuseofwasteironandsteelplant,andprocessahigh-efficiencyenvironmentprotectedrecoveryprocessofwastetirewhichisveryattractive.Inthispaperofthegreendesignprinciple,wedesignthecorrespondingwastetyrecrackingequipment,includingthepreheatingchamber,acrackingchamber,hotblaststove.Comparedwiththeexistingelectricheatingequipment,thebiggestcompetitiveadvantageismainlyembodiedinhotblaststove.Theprocesshasabandonedtheexistinguseofelectricpowerequipment,combineswasteofsteelandironplantandthecrackingofscraptire,whichrecyclesenergy,reducesenergyconsumption,reducesthecost,soithastheverygoodprospect.Thedesignofthepyrolysisprocessofwastetireundernitrogenatmospherewasstudiedanddesigned.Andwedesignedthepreheatingfurnaceandheatingfurnace,improvedtherecoveryandutilizationofwastenitrogenprocess.Thedesignofthe100kilogramsofwastetyrecrackingprocessisconcreteanddetailed,Thepreheatingtemperaturesetat260℃,500℃ofpyrolysistemperaturesetting.Atthesametime,thispapermakesfulluseofinertnitrogen,choosetheverticalcrackingtowerwhichmaketheparticleofwastetireheateduniformly,theenergyutilizedfully.KeywordsWastetireThermalcrackingCrackingdevice毕业设计第I页共Ⅰ页目录1绪论............................................................................................................................................................11.1背景与现状....................................................................................................................................11.1.1废旧轮胎对环境的影响.....................................................................................................11.1.2废旧轮胎传统的处理方式....................................................................................................21.2常压惰性气体热解技术...................................................................................................................31.2.1常压惰性气体热解技术法定义.........................................................................................31.2.2常压惰性气体热解技术法原理.........................................................................................41.2.3废旧轮胎裂解反应的影响因素.........................................................................................51.2.4常压惰性气体热解技术法的特点.....................................................................................51.2.5常压惰性气体热解技术的应用.........................................................................................61.3废旧轮胎的分类和物理参数..........................................................................................................61.3.1轮胎的分类............................................................................................................................61.3.2轮胎规格...............................................................................................................................71.3.3轮胎的速度等级...................................................................................................................71.4课题的提出和主要研究内容........................................................................................................81.4.1课题的提出.........................................................................................................................81.4.2主要研究内容.....................................................................................................................82轮胎参数和裂解反应流程.........................................................................................................................92.1工艺路线..........................................................................................................................................92.2裂解反应的流程...............................................................................................................................93热解技术的主要设备设计.......................................................................................................................113.1预热仓.............................................................................................................................................113.2裂解仓.............................................................................................................................................133.2.1裂解仓中的问题和之前的设备.........................................................................................133.2.2国内外设备比较..................................................................................................................133.2.3立式裂解塔结构............................................................................................................
