5000吨水泥窑生产线设计

洛阳理工学院毕业设计（论文）I大庆水泥公司4800t/d熟料新型干法生产线烧成窑尾工艺设计-P·F32.5；P·O42.5摘要本设计为日产4800吨水泥熟料生产线设计—重点车间：烧成窑尾。烧成车间是水泥成品制备的重要工艺过程，它直接影响水泥质量的好坏，因此水泥烧成车间设计在整个水泥厂的设计中是一个很重要的环节。窑尾系统是由NST-I分解炉、旋风筒、连接管道及附件等组成。此次论文的主要内容是：在配料计算基础上，进行了物料平衡、储库平衡、主机平衡计算，并以此为依据，对全厂储库、主机及辅机进行了选型和工艺布置；重点对烧成窑尾进行了工艺计算、设备规格设计、工艺布置设计。预分解窑生产工艺指采用窑外分解新工艺生产的水泥，其生产以悬浮预热器和窑外分解技术为核心，采用新型原料、燃料均化和节能粉磨技术及装备，全线采用计算机集散控制，实现水泥生产过程自动化和高效、优质、低耗、环保。关键词：烧成窑尾，悬浮预热器，NST-I分解炉洛阳理工学院毕业设计（论文）IIKilnTechnologyDesignof5000t/dCementClinkerProductionLineindaqing-P·F32.5；P·O42.5CementABSTRACTThisdesignisaimattheendofkilntechnicsfor4800t/dripematerialnewtypedryprocesscalcinationsworkshop.Theendofkilnisofcrucialimportanceincementproductionprocess,sinceitdirectlyinfluencesthequalityofthecementproduct.Therefore,thedesignoftheendofkilninthewholeofthecementplant’sdesignisveryimportantaspect.TheendofkilniscomposedofNST-Ibreakdownfurnace,cyclonecanister,jointpipelineandattachment,andsoon.Thisdesigncarriedonthematerialbalance,reservoirbalanceandhostbalancecalculationwhichwerebasedonthecalculationoftheingredients,andasabasis,thewholeplantreservoir,mainandauxiliarymachineryhavingbeenselectedandcarriedonthelayoutprocess;andthenitwascarriedontheprocesscalculation,equipmentspecificationdesign,processlayoutdesignwhichwerefocusonthefiringkiln.Precalciningkilnproductionprocessofthekilnnewtechnologyoftheproductionofcement.Itsproductioninsuspensionpreheaterandkilntechnologyasthecore,usingnewmaterials,fuelandenergysavinggrindingtechnologyandequipment,fulluseofcomputerdistributedcontrolsystem,realizesthecementproductionprocessautomationandhighefficiency,highquality,lowconsumption,environmentalprotection.KEYWORDS:firingkiln，suspensionpreheater,NST-Ibreakfurnace洛阳理工学院毕业设计（论文）III目录前言.........................................................................................................1第1章绪论...............................................................................................21.1设计的目的....................................................................................21.2设计依据......................................................................................31.3工艺设计的原则与指导思想.........................................................31.3.1工艺设计的原则.................................................................31.3.2工艺设计的指导思想..........................................................31.4工厂总平面布置基本原则............................................................4第2章配料计算........................................................................................52.1原始数据.......................................................................................52.2原燃料的评价...............................................................................62.3熟料率值的确定...........................................................................62.4熟料热耗的确定............................................................................72.5计算煤灰掺入量...........................................................................72.6配料计算及结果...........................................................................72.6.1原料配比及理论料耗.........................................................72.6.2计算熟料矿物组成..........................................................102.6.3计算湿原料的配合比.......................................................112.6.4有害气成分的计算...........................................................112.7水泥配比.....................................................................................12第3章物料平衡.......................................................................................143.1烧成车间生产能力和工厂能力的计算......................................143.1.1窑规格的确定...................................................................143.1.2窑的台时产量标定...........................................................143.1.4计算烧成系统的生产能力...............................................153.2原燃材料消耗定额的计算..........................................................153.2.1原料消耗定额..................................................................153.2.2干石膏消耗定额..............................................................16洛阳理工学院毕业设计（论文）IV3.2.3干混合材料消耗定额........................................................163.2.4烧成用干煤消耗定额.......................................................173.2.5水泥产量...........................................................................17第4章主机平衡......................................................................................194.1主机设备的确定.........................................................................194.1.1主机设备工作制度的确定...............................................194.1.2主机设备生产能力的确定................................................194.2石灰石破碎机选型......................................................................204.3砂岩破碎机选型..........................................................................214.4生料磨选型.................................................................................214.5窑选型.........................................................................................234.6煤磨选型.................................................................
