为了提高炼汞沸腾焙烧炉的热效率,延长物料在炉内的停留时间,以降低燃料消耗,提高汞的冶炼回收率,贵州汞矿成功地将2.5m~2单层双稀相沸腾焙烧炉,改成床底内部排料式双层沸腾炉(简称双层炉)。双层炉具有上部沸腾床和下部沸腾床。上部沸腾床为汞矿石的焙烧床,床底面积1.39m~2,锥角47°,床层温度710～750℃,阻力损失1100mm
In order to improve the thermal efficiency of the mercury-fired roasting furnace, extend the residence time of the material in the furnace, reduce the fuel consumption and improve the smelting recovery rate of mercury, the mercury mine in Guizhou successfully succeeded in 2.5m ~ 2 single- Into the bed at the end of discharge double-bed boiling furnace (referred to as double-layer furnace). Double-layer ovens have an upper boiling bed and a lower boiling bed. The upper ebullated bed is a calcined bed of mercury ore with a bed area of 1.39 m 2, a cone angle of 47 °, a bed temperature of 710 to 750 ° C., and a resistance loss of 1100 mm
