稳定蒸汽干燥机运行状况的攻关

干燥机是闪速炼铜工艺过程的重要设备之一,铜精矿通过皮带输送进干燥机,与内部通入蒸汽的盘管接触,将水分蒸发,完成铜精矿的干燥。干燥机运行的好坏直接影响着闪速炉的作业效果,贵溪冶炼厂的蒸汽干燥机在使用过程中出现了进料端堵料、盘管易磨损、换热效率低等问题,通过对设备结构和工艺方法的的改进,从而提高了蒸汽干燥机的作业效率,为提高闪速炉作业率提供了良好条件。

The Solutions of Stable Operation of Steam Dryer

The dryer is one of the important equipments in the flash copper smelting process. The copper concentrate is conveyed into the dryer through the belt, and is in contact with the internal steam-introducing coil to evaporate the water to complete the drying of the copper concentrate. The operation of the dryer directly affects the operation effect of the flash furnace. The steam dryer of the Guixi Smelter has problems such as blocking at the feed end, easy wear of the coil, and low heat exchange efficiency. Improvements in equipment structure and process methods have improved the operating efficiency of the steam dryer and provided good conditions for improving the operating rate of the flash furnace.
