I年产6万吨环氧树脂车间工艺设计设计说明：环氧树脂生产工艺一般分为一步法和二步法。目前低分子量液体环氧树脂和中分子量固体环氧树脂，一般都采用一步法工艺；高分子量环氧树脂采用二步法。本设计用一步法工艺：把双酚A(BPA)和环氧氯丙烷(ECH)在氢氧化钠作用下进行缩聚，即开环和闭环在同一反应条件下进行的工艺方法。以双酚A（BPA）为主要原材料，合成的环氧树脂称为双酚A（BPA）型环氧树脂，是目前产量最大、用途最广的环氧树脂，由于它的应用遍及国民经济的众多领域，因此又称为通用型环氧树脂。本设计用此类环氧树脂。本文从生产工艺技术、经济、管理等方面对年产6万吨环氧树脂进行了详细的论述，内容主要包括：设计依据，工艺路线论证，工艺流程设计，全流程物料衡算，全流程能量衡算，工艺设备选型与计算，车间布置设计，三废处理及其综合利用等。设计主要成果如下：①每天产量理论值181.82t,实际产量为180.70t；实际年产量为5.96万吨。②用水蒸气加热的50000L闭式搅拌溶解釜；用冰盐水冷却的50000L搪玻璃闭式搅拌反应釜，材料为镍铬不锈钢0Cr18Ni9。③主要设备：浆式搅拌器；标准椭圆形上封头，锥形下封头；支承式支座，选用标准为JB/T472—92；釜夹套；1000L环氧氯丙烷回收釜；8000L苯贮槽；30000L脱苯釜；进出料管都选用普通无缝钢管；泵选择屏蔽泵B；过滤器。④图纸包括：1）、工艺流程图2）、物料图3）、反应釜的装配图关键词：环氧树脂，一步法，车间工艺设计IIAnnualoutputof60000tonsofepoxyresinplantprocessdesignDesignNotes:Epoxyresinproductionprocessisgenerallydividedintoone-stepandtwo-step.Presentinlowmolecularweightsolidepoxyresinsandliquidepoxyresin,generallyusingone-stepprocess;highmolecularweightepoxyresinwithtwo-step.Thisdesignonestepprocess:thebisphenolA(BPA)andepichlorohydrin(ECH)inthecondensationundertheactionofsodiumhydroxide,theopen-loopandclosed-loopinthesamereactionconditionsforprocessmethod.Thedesignoftheuseofsuchepoxyresin.TobisphenolA(BPA)asthemainrawmaterial,knownasbisphenolepoxyresinsynthesizedA(BPA)typeepoxyresinistheoutputofthelargestandmostwidelyusedepoxyresin,becauseofitsapplicationthroughoutthenationaleconomymanyareas,so-calledgeneralepoxyresin.Itisethertype.Inthispaper,productiontechnology,economics,managementandotheraspectsofanannualoutputof60000tonsepoxydiscussedindetail,mainlyincluding:thedesignbasis,processroutefeasibilitystudies,processdesign,thewholeprocessmaterialbalance,thewholeprocessofenergyaccountancy,processequipmentselectionandcalculation,plantlayoutdesign,wastetreatmentandcomprehensiveutilization.Designofthemainresultsareasfollows:(1)dailyoutputofthetheoreticalvalue181.82t,actualproductionwas180.70t;actualannualoutputof59600tons.(2)linedwithclosedsteamheating50000Lstirtodissolvekettle;withicecoolingsaline50000Llinedclosedstirredtankreactor,D=3800mm,H=4600mm.Materialforthenickel-chromiumstainlesssteel0Cr18Ni9.(3)Mainequipment:Paddlemixers;standardellipsehead,conicallowerhead;bearingtypebearings,selectioncriteriaJB/T472-92;reactorjacket;1000Lepichlorohydrinrecoverytank;8000Lbenzenetank;30000Ldebenzenizedkettle;accesstomaterialsuseanordinaryIII环氧树脂设计说明DesignNotestubesareseamless;pumpshieldpumpselectionB;filter.(4)Drawingsinclude:1)processflowdiagrams,2)materials,3)reactorassemblydrawingKEYWORDS:Epoxyresin，one-step，workshopprocessdesignⅲ环氧树脂设计说明目录目录1引言.................................................................................................................................................11.1环氧树脂基本概述...............................................................................................
