5000t/d水泥熟料预分解窑窑尾（低氮氧化合物排放）工艺设计摘要：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。以预分解窑为代表的新型干法水泥生产技术已经成为当今水泥工业发展的主导技术和最先进的工艺，它具有生产能力大、自动化程度高、产品质量高、能耗低、有害物排放量低等一系列优点。但在水泥生产过程中会放出一些有害物质，尤其是氮氧化合物，按照要求本设计采用一系列的方法，以求降低氮氧化合物的排放浓度。本设计依据当今新型干法水泥生产技术的设计要求进行，主要任务是窑尾部分的工艺设计，包括新型干法水泥生产对原料、燃料的质量要求，配料方案的设计和配料计算，物料平衡计算，主辅机平衡与设备选型，储库计算和窑尾工艺设计。关键词：5000t/d；预分解窑；低氮排放；工艺设计TheProcessDesignoftheBackEndofPrecalcinerKilnfor5000T/DCementClinker(LowNitrogenOxideEmissions)Abstract:Cementisoneofthemostimportantbuildingmaterialsofthesocialandeconomicdevelopment,withinthecomingdecadesorevenacentury,Cementisstillnosubstituteforbasicmaterials,theimportanceofhumancivilizationisself-evident.calcinerkilnastherepresentativeshasbecomeleadingtechnologyandthemostadvancedtechnologyofthecementindustry.Ithasmanyadvantages,suchashighthroughput,ahighdegreeofautomation,highqualityproducts,lowenergyconsumption,lowemissionsofharmfulsubstances,etc.Intheproductionprocessofcementwillreleaseanumberofharmfulsubstances,particularlynitrogenoxides,accordingtotherequirementofthisdesign,thedesignusesarangeofmethodstoreducetheconcentrationofnitrogenoxide.Basedonthedesignofnewdrycementproductiontechnologyintoday'sdesignrequirements,themaintaskistheback-endpartoftheprocessdesign,includingtheproductionofcementrawmaterials,fuelqualityrequirements,thedesignofingredientsandingredients,thematerialbalancecalculation,themainauxiliarybalanceandequipmentselection,calculationandstorageback-endprocessdesign.Keywords:5000T/D,LowNitrogenEmissions,ProcessPrecalcinerkiln,Design目录第1章绪论.............................................................11.1引言...........................................................11.2设计简介........................................................1第2章建厂基本资料......................................................32.1设计题目...........................................32.2建厂条件…………………………………………………………………32.3原料质量要求....................................................32.3.1水泥原料质量要求.............................................32.3.2石膏和混合材质量要求.........................................42.4燃料品质要求....................................................52.5熟料热耗的选择..................................................62.6生产方法和窑型的选择............................................6第3章配料计算与物料和主机平衡..........................................83.1配料计算........................................................83.1.1原料原始数据.................................................83.1.1.1原燃料化学成分............................................83.1.1.2原、燃料水分..............................................83.1.1.3烟煤的工业分析............................................83.1.1.4烟煤的元素分析............................................83.1.2水泥配料方案..................................................83.1.2.1三个率值的选择............................................93.1.2.2煤灰掺入量...
