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第I页共Ⅰ页毕业设计目录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.....................................................................................
