摘　　要：为解决三产品重介质旋流器中煤带精的问题,在分析研究的基础上,提出了中煤有压再选三段重介质旋流器的设想。文章介绍了该旋流器的结构和工作原理,并借助ANSYS软件,模拟分析了其内部流场分布,得到了切向速度与轴向速度的分布规律,从理论上证实了其结构的合理性。The trouble with the use of a 3-product H.M. cyclone is the entraiment of clean coal in mid- dlings. To tackle this problem, the use of the pressure-fed 3-stage H. M. cyclone for rewashing of mid- dlings is proposed based on the result of analysis and study. The paper presents a brief introduction to the structure and working principle of the cyclone. The law governing the distribution of both tangential and axial velocities is brought to light through simulation and analysis of the distribution of the flow field using ANSYS software. This well demonstrates theoretically the rationality of the structure of the cyclone.
