1、河南理工大学2009届本科毕业设计摘要泉店选煤厂隶属于河南神火煤电股份有限公司，属矿井型炼焦煤选煤厂，厂址位于河南省许昌市泉店矿井工业广场内。本设计所用的资料为泉店矿选煤厂提供，设计日处理量为120万吨的选煤厂.根据入选原煤的煤质特征、选后产品用途和质量要求，确定如下选煤方法：准备至50mm以下原煤采用脱泥无压三产品重介旋流器+旋流静态微泡浮选联合工艺。原煤首先经50mm分级，+50mm块煤人工拣矸后破碎至-50mm。50-0mm入选原煤预先0.75mm脱泥，脱出煤泥再回收+0.35mm粗煤泥与
2、+0.75mm原煤一起给入无压三产品重介旋流器分选，选后产品经脱介、脱水出精煤、中煤、矸石三种产品。稀介质直接磁选，精煤、中矸磁选尾矿分别回收，粗煤泥按煤质分别掺入相应选后产品，细粒煤泥采用旋流静态微泡浮选工艺处理，浮选精矿采用加压过滤机回收掺入重介精煤中。尾煤采用浓缩+压滤回收煤泥，浓缩机的溢流与压滤液作为循环水重复使用。关键词：选煤；无压给料三产品重介质旋流器；浮选102河南理工大学2009届本科毕业设计AbstractStephenstoresShenhuocoalpreparationp
