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,建设节约
高效的选煤厂,都将提高选煤效益,减弱燃煤过程对环境的危害。
本设计所用的资料为晋城无烟煤煤业集团王台铺煤矿提供的煤质筛分、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。
本设计根据煤质特点和动力煤洗选特点:选用+13mm 重介斜轮—13-1mm 重介旋流
—1- 螺旋溜槽流程。对应不同粒级、不同可选性确定不同洗选方法,避免了煤泥浮
选成本高的问题,并对出现的难选及较难选煤有适应性。
关键词:选煤工艺流程;重介分选;螺旋溜槽
Abstract:Coal occupies important position in Chinese sources of energy, world environment
problem's require that we are able to make use of coal cleanly gradually gravely. In building state
enterprises and renovating and enlarging old ones choosing a coal yard, ask the ceaseless
optimization to choose the coal handicraft, equipment choosing advanced selections coal
rationally, the for sure rational workshop building workshop arranges, be fit to wait a minute in
the office procedure choosing a coal yard as well as choosing, construction saves the high-effect
selections coal yard, will improve the damage choosing coal beneficial result, weakening fire coal
process to the environment.
This design uses material anthrax screening, vicissitude material which the coal mine
provides for Jincheng anthracite coal industry group Wang Taipu, first to the collection anthrax
material examination, the adjustment and the synthesis, obtains the curve of wash ability. Then the
basis of washability preliminary definite technical process, putation number quality flow,
the medium and the waterflow are balanced, chooses the appropriate equipment. Finally selects
the situation based on the equipment with the equipment relation chart, carries on the arrangement
to each workshop, and carries on the overall plan to the always industry location. Moreover, this
