武汉工程大学本科毕业（设计）论文I摘要发酵罐是化工生产中实现化学反应的主要设备。其作用：①使物料混合均匀；②使气体在液相中很好分散；③使固体颗粒在液相中均匀悬浮；④使不均匀的另一液相均匀悬浮或充分乳化。目前已广泛地用于制药、味精、酶制、食品行业等。它的主要组成部分包括釜体、搅拌装置、传热装置、轴封装置。还根据需要加其他的附件，如装焊人孔、手孔和各种接管(为了便于检修内件及加料、排料)，安装温度计、压力表、视镜、安全泄放装置(为了操作过程中有效地监视和控制物料的温度、压力)等。釜体是由简体和两个封头组成，它的作用是为物料进行化学反应提供一定的空间。搅拌装置是由传动装置，搅拌轴和搅拌器组成，它的作用是参加反应的各种物料均匀混合，使物料很好地接触而加速化学反应的进行。搅拌装置可以分为非潜水型(仅驱动机和减速机及传动系统露在液体外面和潜水型(从驱动机至搅拌器全部潜入液体内)两种类型。传热装置是在釜体内部设置蛇管或在釜体外部设置夹套，它的作用是使控制物料温度在反应所需要范围之内。本发酵罐的设计容积是63立方米，属于大型罐设计，采用蛇管传热，三级搅拌。关键词：搅拌罐；搅拌器；釜体；传热装置；轴封装置；人孔武汉工程大学本科毕业（设计）论文IIAbstractFermentationisachemicalreactiontoachievetheproductionofmajorequipment.Itsroleis:①tomixedmaterials;②thegasiswelldispersedintheliquidphase;③makinguniformsolidparticlessuspendedinliquid;④sounevensuspensionorotherliquidemulsifiedinuniform。Fortheuniformreaction,nowiswidelyusedinpharmaceutical,monosodiumglutamate,enzymesystemandfoodindustries.Itsmaincomponentsincludethereactorbody,mixingequipment,heattransferequipmentandsealdevice.Alsoaddotheraccessoriesneeded,suchasassemblyandweldingmanhole,handholeandallover(inpiecesforeaseofmaintenanceandfeeding,nesting),installthermometers,pressuregauges,mirrors,safetyreliefdevice(foroperationeffectivelymonitorandcontrolthematerialtemperature,pressure)andsoon.Mixingdeviceisagear,shaftandagitatorstirringcomposition,itsroleistoparticipateinavarietyofmaterials,reactionmixedevenly,sothatgoodcontactmaterialtoacceleratethechemicalreaction.Mixingdevicescanbedividedintonon-divingtype(onlydrivenmachinesandgearandtransmissionsystemdisclosedintheliquidoutsideanddivetype(fromthedrivingmachinetosneakintoaliquidblenderall)types.Heattransferdeviceissetintheinteriorofreactorbodycoilorexternaltanksetupinthejacket,itsroleistocontrolthematerialsneededinthereactiontemperaturerange.Thedesignofthefermentationtankvolumeis63cubicmeters,andthisisalargetankdesignwithcoilheattransferandthreemixings.Keywords:mixingtank；mixer；kettlebody；heattransferequipment；sealdevice；manhole.武汉工程大学本科毕业（设计）论文III目录摘要...........................................................IAbstract..........................................................II前言...........................................................I概论..........................................................II1、发酵罐的特点................................................II2、发酵罐的工作要求............................................II3、发酵罐的设计依据............................................II4、发酵罐的设计要求............................................II5、发酵罐的设计步骤............................................II6、设计内容...................................................III第一章设计参数的选择.............................................11.1、课程设计题目...............................................11.2、原始数据...................................................11.3、已知条件...................................................11.4、设计压力...................................................21.5、设计温度...................................................21.6、材料的选择.................................................21.7、基本的选型.................................................3第二章容器的结构设计.............................................32.1、圆筒的设计.................................................32.1.1、圆筒的高和直径........................................32.1.2、圆筒的厚度............................................42.2、封头壁厚...................................................52.3、所装料液高度...............................................63、厚度裕量.....................................................74.1、轴的设计及校验.............................................74.2、传动轴长度.................................................74.3、轴径.......................................................7武汉工程大学本科毕业（设计）论文IV4.4、临界转速...................................................84.4.1、有效质量的计算.......................................124.4.2、一阶临界转速的计算...................................134.5、按强度计算搅拌轴的轴径....................................144.6、轴向的弯矩的计算：........................................175、径向位移验算轴径............................................18第三章主要部件的选择............................................213.1、减速机....................................................213.2、联轴器....................................................213.3、密封......................................................213.4、底轴承....................................................223.5、对支承的改进..............................................22第四章传热计算..................................................234.1、传热面积..................................................234.2、蛇管总体长度..............................................234.3、蛇管组及每组长度...........................错误!未定义书签。4.4、每级蛇管排列圈数...........................错误!未定义书签。4.5、传热面积的校验.............................错误!未定义书签。4.5.1、冷却水耗量............................错误!未定义书签。4.5.2、传热面积校核..........................错误!未定义书签。第五章开孔补强及校核............................................255.1、人孔补强..................................................315.2出料口接管补强..............................................335.3进气口接管补强..............................................355.4、水压试验应力校核.............................
