1.80Mta矿区型选煤厂矿物加工工程本科生毕业论文设计.doc

PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT II Ⅰ Ⅰ 本科毕业设计论文 论文题目：鲍店1.80Mt/a矿区型选煤厂 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 PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT 1 Ⅱ Ⅱ Abstract Coal in Chinas energy occupies an important position in the world of increasingly serious environmental problems, we can require the use of clean coal. In the new coal preparation plant, alteration, extension, it is necessary to continuously optimize the coal preparation process, a reasonable choice of advanced coal preparation equipment, determine a reasonable layout of the factory workshop, and choose suitable for coal preparation plant management methods, and so on, down Improve the efficiency of coal preparation, construction, conservation and efficient coal preparation plant, will keep weakening these issues. 5The design of data used for coal in Henan Shenhuo Coal Mine Co., Ltd. Xuehu the coal preparation plant to provide screening, the first coal quality data collected by the review, correction, and comprehensive, are optional curve. Based on a preliminary set of optional process, the calculations of the quality processes, media and water flow balance, choice of appropriate equipment. The final selection based on equipment and associated equipment plans, conduct workshops on various layout and industrial sites in the overall plan. In addition, the design of production facilities, environmental protection, labor, and other aspects of the quota on. According to the design characteristics of coal. Designed with three-product referral and flotation process, the applicat
