I摘要水泥是社会经济发展最重要的建筑材料之一，在今后几十年甚至是上百年之内仍然是无可替代的基础材料，对人类生活文明的重要性不言而喻。现代最先进的水泥生产技术就是新型干法预分解窑。预分解窑是在悬浮预热器与回转窑之间增设分解炉，在分解炉中加入占总用量50%-60%的燃料，使燃料燃烧的过程与生料碳酸盐分解的吸热过程在悬浮状态或沸腾状态下迅速进行，从而使入窑生料的分解率从悬浮预热窑的30%-40%提高到85%-90%，使窑的热负荷大为减轻，窑的寿命延长，而窑的产量却可成倍增长。与悬浮预热器窑相比，在单机产量相同的条件下，预分解窑具有:窑的体积小，占地面积减小，制造、运输和安装较易，基建投资较低，且由于一半以上的燃料是在温度较低的分解炉内燃烧，，产生有害气体NOｘ较少，减少了对大气的污染。本设计内容为日产5500吨水泥熟料新型干法生产线回转窑工艺设计，根据配方比例和原燃料的数据分析，计算三大平衡，并进行了烧成工艺设计，参照其它国内外的水泥厂进行了回转窑工艺设计，确定回转窑规格，最终符合生产实际要求。关键字：回转窑三大平衡工艺设计IIAbstractCementisoneofthemostimportantbuildingmaterialsofthesocialandeconomicdevelopment,withinthecomingdecadesorevenacentury,Cementisstillnosubstituteforbasicmaterials,theimportanceofhumancivilizationisself-evident.ModernmostadvancedcementproductiontechnologyisNSPkilnadvancedecomposition.Predecompositionkilnisinsuspensionperheaterbetweendecomposingfurnacewithrotarykilnadded,joinincalcinerintotalamount50%-60%offuel,tomakethefuelburningprocessandrawintheabsorptionprocessdecomposecarbonatestateofsuspensionorboilingcondition,thusmakerapiddecompositionrateofkilnrawfromsuspensionpreheaterkiln30to40percentoftheincreasedto85percentto90percent,theheatloadofkilnisreducedgreatly.Comparedwithsuspensionpreheaterkilnindividualoutput,inthesameconditions,thedecompositionfurnacewith:smallsize,coversanareaofreduced,manufacturing,transportationandinstallationeasier,lowinvestmentininfrastructure,andbecausemorethanhalfoffuelisinthelowertemperatureburninginprecalciner,,produceharmfulgases,andreducedtherateoflessNOxatmosphericpollutionThedesignofthecontentofNissan5500tonsdryprocessrotarykilncementproductionlineprocessdesign,Accordingtotheoriginal,thefuelofdataanalysis,Iworkoutthecalculationofthethreebalanceandthecalculationforthefiringprocess.Refertootherstate-of-the-artcementplantforrotarykilntechnologydesign,furtherdeterminethespecificationsforthedesignofrotarykiln,andadapttotheactualrequirement.III目录摘要...................................................................................................................................IAbstract...................................................................................................................................II目录........................................................................................................................................III前言..........................................................................................................................................11设计任务...............................................................................................................................21.1任务............................................................................................................................21.2重点解决问题............................................................................................................21.3工厂原始资料............................................................................................................22配料计算...............................................................................................................................32.1三个率值的选择........................................................................................................32.2计算煤灰掺入量........................................................................................................42.3计算干燥原料配合比................................................................................................42.4熟料的矿物组成计算................................................................................................53物料与主机平衡...................................................................................................................73.1物料平衡计算............................................................................................................73.1..1烧成车间生产能力和工厂生产能力的计算................................................83.1.2原料消耗定额.................................................................................................93.2原料、燃料、材料需要量的计算和物料平衡表的编制......................................114工艺设备选型与计算.........................................................................................................134.1工艺设备选型与计算的目的..................................................................................134.2设备选型..................................................................................................................144.2.1石灰石破碎设备的选型[7]..........................................................................14IV4.2.2生料磨的设备选型.......................................................................................154.2.3回转窑选型..................................................................................................164.2.4煤磨的选型...................................................................................................174.2.5水泥磨的设备选型.......................................................................................184.3包装机的设备选型..................................................................................................194.3主机平衡表见表.....................
