高分选密度重介质旋流器的研究与应用

Research and Application on Heavy Medium Cyclone of High Separation Density

针对大型动力煤选煤厂分选密度高的特点,通过数值模拟和试验研究,研发了新型高密度旋流器,实现了分选效率高、电耗低的效果。将其应用于处理能力400 Mt/a选煤厂,与原系统相比,节约用电7.92万k W·h/a,节省电费3.96万元/a。

According to the characteristics of high density in the large Thermal coal preparation plant, through the numerical simulation and experimental research, a new type of cyclone with high density was researched and developed. The cyclone has realized the separation effect of high efficiency, low power consumption. The cyclone could be applied to the coal preparation plant of 4 000 000 tons per year. In comparison with the original system, the electric power consumption could be saved with 79200 kW. h per year. The electricity could be saved with 39 600 Yuan per year.
