隧道窑毕业设计

2008届本科毕业生设计（论文）年产70万平方米玻化砖液化石油气辊道窑设计1摘要本设计说明书对所设计的年产70万平方米玻化砖辊道窑加以说明。说明书中具体论述了设计时应考虑的因素,诸如窑体结构、排烟系统、烧成系统和冷却系统等等.同时详细的进行了对窑体材料的选用、热平衡、管路、传动设计等的计算。本次设计窑炉的燃料为液化石油气，在烧成方式上采用明焰裸烧的方法，既提高了产品的质量和档次，又节约了能源，辊子运输可减少窑内装卸制品，和窑外工序连在一起，操作方便，同时具有很高的自动化控制水平，在燃烧及温度控制上采用PID智能仪表，可以很方便的调节和稳定烧成曲线。本说明书内容包括：窑体主要尺寸的确定、工作系统的确定、窑体材料的选择、燃料燃烧计算、热平衡计算、传动计算、管道尺寸阻力计算、风机的选型及工程材料概算。2008届本科毕业生设计（论文）年产70万平方米玻化砖液化石油气辊道窑设计2AbstractThisinstructionelaboratedtherollerkiln.Theannualproductionofthisrollerkilnis700thousandsquaremeterporcelainbrick.Thisinstructionspecificallyelaboratedthefactorshouldconsideredwhenwedesigned,suchasthestructureofthekilnbody,dischargedsystem,burningsystemandthecoolingsystemandsoon,Atthesametimeitdetailedhowtochoosethemeterial,thecalculationofheatbalance,thepipelinedesign,thetransmissiondesigntothekilnandsoon.Thisfuelofthekilnisliquefiedpetroleumgas,itfiresproductdirectly.Thisfiringwaycanimprovedthequalityandscaleoftheproduct,savedtheenergy,andthetransportationbyrollermayreduceloadingtheproduct.Withtheworkingprocedureoutsidethekiln,Iteasedtheoperation.Simultaneouslyithasthehighautomationcontrollevel.ItusesthePIDintelligencemeasuringapplianceinfiringandthetemperaturecontrol.Itcanadjustthefiringcurveandmakethetemperaturestablyconveniently.Thisinstructioncontentincludes:thedeterminationofkilnbodydimension,worksystem,thechoiceofmaterial,thecalculationoffuelburning,thecalculationofheatbalance,thecalculationoftransmission,thecalculationofpipelinesizeandresistance,2008届本科毕业生设计（论文）年产70万平方米玻化砖液化石油气辊道窑设计3howtochooseairblowershapingandtheestimationofengineerigmaterial.目录前言...................................................................62008届本科毕业生设计（论文）年产70万平方米玻化砖液化石油气辊道窑设计41原始资料收集..........................................................72窑体主要尺寸的确定....................................................82.1进窑砖坯尺寸.....................................................82.2内宽的确定与排砖方法.............................................82.3内高的确定.......................................................92.4烧成制度的确定...................................................92.5窑长及各带长的确定..............................................102.5.1窑长的确定................................................102.5.2各带长的确定..............................................112.5.3辊道窑窑头、窑尾工作台长度................................122.5.4窑体总长度的确定..........................................123工作系统的确定.......................................................123.1排烟系统........................................................123.2燃烧系统........................................................133.2.1烧嘴的设置................................................133.2.2助燃系统..................................................143.2.3液化石油气输送系统........................................143.3冷却系统........................................................143.3.1急冷通风系统..............................................143.3.2缓冷通风系统..............................................153.3.3快冷通风系统..............................................153.4温度控制系统....................................................153.4.1热电偶的设置..............................................153.4.2温度仪表选型..............................................163.5传动系统........................................................163.5.1辊棒的选择................................................163.5.2传动装置..................................................163.5.3辊距的确定................................................173.5.4辊棒的联接形式............................................173.5.5传动过程..................................................183.6窑体附属结构....................................................183.6.1事故处理孔................................................183.6.2观察孔与测温口............................................193.6.3膨胀缝....................................................193.6.4下挡墙和上档板............................................193.6.5钢架结构..................................................203.6.6测压孔....................................................204窑体材料确定.........................................................204.1窑体材料确定原则................................................204.2整个窑炉的材料表................................................205燃料及燃烧计算.......................................................215.1理论空气量计算：................................................225.2烟气量计算......................................................225.3燃烧温度计算....................................................222008届本科毕业生设计（论文）年产70万平方米玻化砖液化石油气辊道窑设计56物料平衡计算.........................................................237热平衡计算...........................................................247.1热平衡示意图....................................................247.2热收入项目......................................................257.2.1坯体带入显热1Q............................................257.2.2燃料带入化学热及显热fQ...................................257.2.3助燃空气带入显热aQ........................................257.2.4预热带漏入空气带入显热aQ..................................257.3热支出项目......................................................267.3.1热制品带出显热2Q.............................
