多膛炉在活性炭工业上的应用

为了提高颗粒活性炭的利用效率,必须对已经饱和的活性炭进行再生。多炉膛是活性炭生产和再生的主要设备。介绍了多炉膛的结构及其工艺流程,并从5个方面介绍了其主要优点。详细分析了多炉膛在活性炭生产和再生过程中的主要工艺参数,包括炉内温度、中轴转速、炉膛压力和活化蒸汽量。最后指出随着颗粒活性炭在水处理、果葡糖浆脱色等行业的大量应用,多炉膛用于规模化生产和再生颗粒活性炭的前景也十分广阔。 To improve utilization rate of granular activated carbon,the spent activated carbon exhausted with wastewater treatment and other fields has to be regenerated.The multiple hearth furnace is an indispensable device for activated carbon production and regeneration.Introduce its structure,technological process as well as its five advantages.Emphasize its main technological parameters such as furnace temperature,shaft rotary speed,hearth pressure and steam volume.The results show that,with the growing consumption of activated carbon in wastewater treatment and HFCS(high fructose corn syrup) decolorization,it would be a trend that multiple hearth furance was applied to most of the granular activated carbon production and regeneration
