Method for synergetic resource treatment of waste incineration fly ash and waste hydrogenation catalyst
The invention belongs to the technical field of treatment of hazardous wastes containing heavy metals, and particularly discloses a method for synergistic resource treatment of waste incineration fly ash and a waste hydrogenation catalyst. The waste incineration fly ash and the waste hydrogenation catalyst are placed in a multi-hearth furnace in a layered mode to be roasted, the waste hydrogenation catalyst is located on the upper portion, the waste incineration fly ash is located on the lower portion, chlorine is decomposed from the waste incineration fly ash through heating, and the chlorine reacts with oxidized molybdenum trioxide and nickel oxide in the waste hydrogenation catalyst to generate dichloromolybdenum dioxide and nickel chloride; and after a certain temperature is reached, the dichloromolybdenum dioxide and the nickel chloride sublimate, are taken out of the multi-hearth furnace by airflow, are respectively condensed and deposited through pipelines with different temperatures, and are collected and recycled. The method is simple to operate, does not generate any wastewater, and realizes dual resource utilization of the waste incineration fly ash and the waste hydrogenation catalyst.
本发明属于含重金属危险废物处理技术领域，具体公开了一种协同资源化处置垃圾焚烧飞灰和废加氢催化剂的方法。将垃圾焚烧飞灰与废加氢催化剂分层放入多底炉中焙烧，废加氢催化剂在上，垃圾焚烧飞灰在下，通过加热使垃圾焚烧飞灰分解出氯气，并与废加氢催化剂中氧化后的三氧化钼和氧化镍反应生成二氯二氧化钼和氯化镍；在达到某一温度后，二氯二氧化钼与氯化镍升华，被气流带出多底炉并通过不同温度的管道使其分别冷凝沉积下来并进行收集回收。该方法操作简单，不产生任何废水，实现了垃圾焚烧飞灰和废加氢催化剂的双重资源化利用。
