毕各庄40Mt选煤厂设计

内蒙古科技大学毕业设计说明书I毕各庄4.0Mt/a选矿厂设计摘要本设计任务为唐山毕各庄矿井型4.0Mt/a选煤厂，毕各庄是隶属于开滦集团的矿井型选煤厂。首先根据生产大样和浮沉试验资料的分析与综合，绘制可选性曲线；根据原煤的性质及精煤质量要求等,评定原煤为难选煤。在进行选煤方案比较的基础上，确定采用重介-浮选联合流程的选煤方法，并制定了工艺流程；然后经过工艺流程计算、设备选型，对主厂房和总平面进行布置，并进行了图纸的绘制。同时做出了该厂的经济技术分析，可知该设计实用性较高。关键字：难选煤；重介-浮选；设备选型；工艺布置内蒙古科技大学毕业设计说明书IIBigeVillage4.0Mt/aconcentratordesignAbstractThisisaprocessdesignforthe4.0Mt/atypemineofcoalpreparationplantinBigeVillageofTangshan.BigeVillageattachestothemine-modelcoalpreparationplantofKailuaGroup.Firstofall,accordingtotheproductiondetailsandanalysisandsynthesisoffugitivedusttestdata,drawthewashabilitycurves,Washabilitycurvedrawing;Accordingtothenatureoftherawcoalandplantqualityrequirements,etc.,toevaluatetherawcoalincoal.Onthebasisofcoalpreparationschemecomparison,Determinethedensemedia-flotationcoalpreparationmethodofthejointprocess,Andformulatetheprocessflow;Andthenthroughtheprocesscalculation,equipmentselection,themainplantandtotalplanelayout,anddrawingthemap.Atthesametimemadetheplant'seconomictechnicalanalysis,practicalityishigher,thedesign.Keywords:difficultseparationcoal;Theheavy–flotation;Equipmentselection;Processarrangement内蒙古科技大学毕业设计说明书I目录摘要...............................................................IABSTRACT............................................................II第一章设计概要...................................................11.1项目背景......................................................11.2可行性研究概要................................................11.2.1原煤资料分析.............................................11.2.2选煤产品组成.............................................11.2.3选煤厂设计生产能力.......................................11.2.4选煤厂位置与交通.........................................11.2.5选煤方案的拟定...........................................11.2.6工艺流程.................................................11.2.7设备选择.................................................2第二章煤质资料的分析与综合.........................................32.1煤质资料的审查分析.............................................32.1.1煤质资料的审查............................................32.1.2煤质资料的分析............................................92.1.3筛分资料分析..............................................92.1.4浮沉资料分析..............................................92.1.5可选性分析................................................9第三章选煤方法与工艺流程的制定.....................................123.1选煤方法和入选方式............................................123.2选煤方法的比较................................................123.2.1、跳汰分选指标计算........................................123.2.2重介（三产品）分选指标计算...............................153.2.3理论与设计指标对比表.....................................183.2.4工艺流程的确定...........................................193.3工艺流程的简述及特点..........................................193.3.1工艺流程说明.............................................193.3.2工艺流程的特点...........................................20第四章工艺流程的计算...............................................224.1准备作业的计算................................................224.2分选作业的计算................................................224.3工艺设备的选型与计算..........................................404.3.1工艺设备选型的原则和规定.................................404.3.1.1设备选型的原则......................................404.2.1.2不均衡系数的确定....................................404.2.2设备的选型与计算.........................................40内蒙古科技大学毕业设计说明书II4.2.2.1原煤筛分设备........................................404.2.2.2破碎设备的选型与计算................................404.2.2.3分选设备的选型与计算................................414.2.2.4末煤及煤泥脱水设备的选型与计算......................434.2.3分级和浓缩设备的选型与计算...............................444.2.4.辅助设备的选型与计算....................................454.2.4.1运输设备............................................454.2.4.2储煤设备............................................494.3工艺布置图...................................................514.4主厂房工艺布置图..............................................524.5场地运输......................................................52第五章生产辅助设施.................................................545.1设施概况......................................................545.1.1机电修理车间.............................................545.1.2空压机车间...............................................545.1.3浮选药剂站...............................................545.1.4介质库...................................................545.1.5材料库...................................................545.2生产技术检查...............................................545.2.1数量检查.................................................555.2.2质量检查.................................................555.3.3化验室及煤样式...........................................555.3给排水........................................................555.3.1用水量及水压.............................................555.3.2给水系统.................................................565.3.3排水系统.................................................565.3.4浓缩机...................................................565.4电气.........................................................575.4.1供配电...................................................575.4.2供配电系统................
