河南理工大学2013届本科生毕业设计(论文)矿物加工工程专业本科毕业论文论文题目：鲍店1.80Mt/a矿区型选煤厂学生姓名：周鹏学号：310906030228指导教师：路阳专业：矿物加工工程年级：09级-2班学校：河南理工大学河南理工大学2013届本科生毕业设计(论文)Ⅰ摘要煤炭在中国能源中占有重要地位，世界环境问题的日益严重,都要求我们能够洁净的利用煤炭。在选煤厂的新建、改建、扩建中，要不断的优化选煤工艺，合理选择先进的选煤设备，确定合理的厂房车间布置，以及选择适合于选煤厂的管理方法等等，都将提高选煤效益，建设节约高效的选煤厂，都将不断的弱化这些问题。本设计所用的资料为兖州鲍店选煤厂提供的煤质筛分、浮沉资料，首先对收集的煤质资料的审查、校正和综合，得到可选性曲线。然后根据可选性初步确定工艺流程，计算数质量流程、介质和水流程平衡，选择合适的设备。最后依据设备选用情况和设备联系图，对各个车间进行布置，并对总的工业场地进行总体规划。另外，本设计还对生产辅助设施、环保、劳动定员等方面进行了阐述。本设计根据该厂的煤质特点，设计采用三产品重介+浮选流程，工艺流程简单适用，易于生产管理。对矿区难选及较难选煤质较为适应，设计向着简单高效重介工艺选煤方向发展。关键词：选煤；重介；三产品旋流器河南理工大学2013届本科生毕业设计(论文)ⅡAbstractCoalinChina'senergyoccupiesanimportantpositionintheworldofincreasinglyseriousenvironmentalproblems,wecanrequiretheuseofcleancoal.Inthenewcoalpreparationplant,alteration,extension,itisnecessarytocontinuouslyoptimizethecoalpreparationprocess,areasonablechoiceofadvancedcoalpreparationequipment,determineareasonablelayoutofthefactoryworkshop,andchoosesuitableforcoalpreparationplantmanagementmethods,andsoon,downImprovetheefficiencyofcoalpreparation,construction,conservationandefficientcoalpreparationplant,willkeepweakeningtheseissues.5ThedesignofdatausedforcoalinHenanShenhuoCoalMineCo.,Ltd.Xuehuthecoalpreparationplanttoprovidescreening,thefirstcoalqualitydatacollectedbythereview,correction,andcomprehensive,areoptionalcurve.Basedonapreliminarysetofoptionalprocess,thecalculationsofthequalityprocesses,mediaandwaterflowbalance,choiceofappropriateequipment.Thefinalselectionbasedonequipmentandassociatedequipmentplans,conductworkshopsonvariouslayoutandindustrialsitesintheoverallplan.Inaddition,thedesignofproductionfacilities,environmentalprotection,labor,andotheraspectsofthequotaon.Accordingtothedesigncharacteristicsofcoal.Designedwiththree-productreferralandflotationprocess,theapplicationprocessissimple,easytoproductionmanagement.Mineelectionofhardcoalandmoredifficulttoadapttotheelection,simpleandefficientdesigntowarddensemediumprocessCoaldirection.Keyword:Coalpreparation,densemedium,thethreeproductsdensemediumcyclone河南理工大学2013届本科生毕业设计(论文)I目录摘要.................................................................................................................................................ⅠAbstract..................................................................................................................................................Ⅱ1绪论...................................................................................................................................................12选煤厂概况......................................................................................................................................12.1设计任务...............................................................................................................................22.2矿区概述...............................................................................................................................22.3选煤厂概况...........................................................................................................................32.4选煤厂设计原则和要求....................................................................................................52.5厂型、厂址及工作制度....................................................................................................72.5.1选煤厂工作制度......................................................................................................72.5.2选煤厂生产能力......................................................................................................7表2-2实际与理论分选密度差值...................................................................................73工艺部分...........................................................................................................................................73.1煤层、煤质特征以及煤的可选性..................................................................................73.1.1煤质特征分析...........................................................................................................83.1原煤资料表.........................................................................................................................104可选性曲线绘制及分析.............................................................................................................184.2工艺流程介绍............................................................................................................185流程计算.........................................................................................................................................205.1准备作业.....................................................................................................................205.2数质量流程的计算...................................................................................................206工艺设备的选型与计算..............................................................................................................436.1工艺设备选型的一般原则..............................................................................................436.2主选设备（三产品重介质旋流器）的选取...........................................
