摘要
在管式反应炉上,通过加入有机氯(PVC)和无机氯(NaCl)研究了垃圾焚烧时氯对重金属迁移特性的影响。结果表明,在低温下,氯对重金属的挥发几乎没有影响,只有在较高的反应温度下氯才会对重金属的挥发特性产生影响,且垃圾焚烧过程中氯的存在使重金属更易向飞灰或烟气中迁移,垃圾中有机氯对重金属迁移特性的影响要大于无机氯。氯的存在会显著改变分布在飞灰和烟气或底渣和飞灰之间的重金属的分布特性。
Effects of chlorine on heavy metals distribution at different temperatures are studied with mixed wastes incinerated in a quartz tube by adding organic chlorine (PVC) and inorganic chlorine (NaCl). The results indicate that the chlorine content in wastes has no influences on heavy metals distribution at lower temperature. Only at higher temperature the influences can be detected. When chlorine is contained in wastes incineration, heavy metals will transfer to fly ash or flue gas more easily. The organic chlorine has more impacts on heavy metals transfer characteristics than inorganic chlorine. The chlorine can obviously alter distribution characteristics of the heavy metals that disperse between fly ash and flue gas or between bottom ash and fly ash.
