摘要要完成了30t/日（70g/m2）胶版纸造纸车间的初步设计。首先对设计方案论证,确定工艺参数,根据所选的参数进行浆水平衡计算,然后根据计算的结果并结合工厂的生产实践进行设备选型,根据选型的结果进行绘制车间平面布置图,,最后进行经济概算,并给出了工艺流程图。设计中采用了ZW24型1760纸机，设计车速为200m/min。为了便于纸机的运行，车间的设计采用了两层布置，面积为2991.4m2，其中长127.3m，宽18m。工艺方面，采用了20%麦草浆、30%阔叶浆和50%针叶浆三种原料进行抄造，并进行了打浆、AKD中性施胶、加填、和表面施胶等。设计的总投资为3866.61万元，回收期为4.8年。关键词：胶版纸造纸车间工艺平衡计算车间平面布置IntroductionofPapermakingWorkshopProducingtheOffsetPrintingPaper(30T/D,70g/m2)Thisdesignisaboutapapermakingworkshopproducingoffsetprintingpaper,withthebaseweightof70g/m2,production30tons/day.Itincludesthedemonstrationoftheproductionprocess,balancecalculationofthepulpandwater,balancecalculationofheat,calculationofinvestmenteconomy,drawingoftheworkshoparrangement,drawingoftheproducingprocessetc.Thepapermachineusedinthisdesignis1760papermachine,thedesignedpapermachinespeedisabout200m/min..Thispapermakingworkshoppossessesaareaofxxxxxxsquaremeters,withxxxmetersinlength,xxxxmetersinwide.Twolayarrangementmakesitveryconvenienttorunthepapermachine.Bleachedreedpulpandthebleachedhardwoodpulpisusedinthemakingoftheoffsetprintingpaperattheratioofxxxxandxxxxrespectively.Themainproducingprocessincludespulping,interiorsizingwithAKD,addingfiller,surfacetreatmentetc.Thetotalinvestmentofthispaperproducinglineisxxxx,therecoveredperiodisabout6years.Keyword:offsetprintingpaper,papermakingworkshop,processbalancecalculation,drawingofworkshoparrangement目录前言……………………………………………………………………………………………11.总论………………………………………………………………………………………31.2设计范围………………………………………………………………………………31.3设计指导思想………………………………………………………………………32.工艺论证及流程设计……………………………………………………………………42.1技术指标………………………………………………………………………42.2纤维原料的选择与配比………………………………………………………………52.3打浆工艺………………………………………………………………………62.3辅料的选择………………………………………………………………………72.3.1施胶剂的选择…………………………………………………………………72.3.2干强剂的选择………………………………………………………………82.3.3助留剂的选择………………………………………………………………82.3.4填料的选择………………………………………………………………82.3.5调色剂的选择………………………………………………………………92.3.6表面施胶剂选择……………………………………………………………102.3.7辅料的使用及加入方式……………………………………………………102.4供浆系统……………………………………………………………………………112.4.1浆料混合……………………………………………………………………112.4.2浆料贮存……………………………………………………………………112.4.3冲浆稀释……………………………………………………………………122.4.4浆料净化筛选………………………………………………………………132.4.5流送上网………………………………………………………………132.5网部………………………………………………………………………………132.6压榨部………………………………………………………………………………142.7干燥部……………………………………………………………………………...
