1、本科毕业设计论文论文题目：鲍店1.80Mt/a矿区型选煤厂II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
2、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IIAbstractCoalinChina'senergyoccupiesanimportantpositionintheworldofincreasingl
