第1页1设计总说明隧道窑的优点是操作连续、生产能力大、燃料消耗低、使用寿命较长、机械化、自动化程度较高、劳动条件较好、烧成制度易于控制及产品质量较高。隧道窑有大小两种窑型，后者截面温差较小，调节灵活，成品率较高，设备重量较轻，制造方便。隧道窑前设有干燥器不仅可以简化工艺、减少砖坯搬运的破损及减轻扬尘，且为全盘机械化、自动化创造条件。目前，我国耐火材料和陶瓷工业所用隧道窑种类较多，且大多数是我国自行设计建造的，已经累积了较为丰富的经验。但在自动控制，节约能源等方面仍然有很多工作窑做。本文详细介绍了165米年产30000吨超高温镁质耐火材料标准砖隧道窑的总体设计过程。主要包括设计技术数据，材质的选择，结构特点，压力平衡设计，燃料燃烧计算，热平衡和风机的选择。该窑的主要特点是高温调节灵活，在不缺氧的条件下烧成温度是1600℃，燃料消耗量为395Kg/h,节约了大量的燃料，成品率为95%，全窑的自动化水平较高，实现自动控制，劳动条件较好，劳动效率较高。关键词：超高温，隧道窑，设计，镁质第2页ThetotaldesignedtoshowthatTunnelkilnhastheadvantageofcontinuousoperation,largeproductioncapacity,lowfuelconsumption,longservicelife,highdegreeofmechanization,automation,goodworkingconditions,firingsystemiseasytocontrolandhighproductquality。Tunnelkilnwhichhastwokindsofsize,type,andthelattersectiontemperaturedifferenceissmall,flexibleadjustment,highyield,thedeviceislightinweightandeasyfabrication。Beforethetunnelkilnwithdriercannotonlysimplifyprocesses,reduceadobehandlingdamageandreducethedust,andtocreateconditionsforsystemmechanization,automationThisarticleintroducedthe165metersannualoutputof30000tonsofultrahightemperaturestandardbricktunnelkilnofmagnesiarefractoryoveralldesignprocess.Maintechnicaldataincludingdesign,materialselection,structuralcharacteristics,pressurebalancedesign,fuelcombustioncalculation,heatbalanceandtheselectionoffanThemaincharacteristicsofthekilnishightemperatureadjustmentflexible,undertheconditionofnothypoxiasinteringtemperatureis1600℃,andthefuelconsumptionof395kg/h,savealotoffuel,theyieldwas95%,thekilnofhighautomationlevel,toachieveautomaticcontrol,andbetterworkingconditions,highlaborefficiencyKeywords：Ultrahightemperature，tunnelkiln,，design,，magnesia第3页目录1设计总说明...............................................................................................................12原始资料的收集.......................................................................................................63镁砖的生产工艺.......................................................................................................73.1原料的要求.......................................................................................................................73.2颗粒组成及配料...............................................................................................................74温度、压力和气氛制度的确定...............................................................................84.1温度制度...........................................................................................................................84.2压力制度..........................................................................................................................84.3气氛制度...........................................................................................................................95隧道窑总体设计......................................................................................................95.1隧道窑内容纳窑车数的确定...........................................................................................95.2每辆窑车装砖量的确定...................................................................................................95.3窑车尺寸的确定..............................................................................................................95.4窑长的确定......................................................................................................................95.5窑的截面积尺寸的确定................................................................................................105.5.2窑宽度的确定......................................................................................................105.6窑各带的划分及长度的确定.........................................................................................105.7有效容积的计算和装窑密度的计算............................................................................115.8窑车数量的确定............................................................................................................116隧道窑各带结构的确定.........................................................................................116.1预热带烟道和气幕配置................................................................................................116.1.1.预热带烟道以及排废气孔数量的确定..............................................................116.1.2隧道窑预热带气幕装置......................................................................................126.1.3窑内横向循环.....................................................................................................136.2烧嘴的确定....................................................................................................................136.3热风抽出系统................................................................................................................136.4冷风鼓入系统.................................................................................................................136.5窑底压力平衡装置........................................................................................................146.6窑门的设置....................................................................................................................147窑墙、窑顶和窑车衬砖设计.....
