Electrolytic manganese residue harmless treatment method and asphalt pavement recycled aggregate preparation device thereof
The invention belongs to the technical field of manganese slag treatment, and particularly relates to an electrolytic manganese slag harmless treatment method and an asphalt pavement recycled aggregate preparation device thereof.The treatment method comprises the following steps that S1, temperature control is conducted on a muffle furnace in advance, the temperature of the muffle furnace is controlled to be 0 DEG C, and then original manganese slag is put into the muffle furnace; s2, the interior of the muffle furnace is heated, the original manganese slag is calcined, the temperature control curve is 0-800 DEG C, and the heating rate is 10 DEG C/min; keeping the temperature at 800 DEG C for 60 minutes; the temperature is 800-1550 DEG C, and the heating rate is 5 DEG C/ Keeping the temperature at 1550 DEG C for 180 minutes; s3, the manganese slag finished product obtained after calcination is completed is put into a roller slag cooler, and the manganese slag finished product is cooled to the room temperature; and S4, the cooled manganese slag finished product is put into a pulverizer. The electrolytic manganese residues are subjected to innocent treatment in a multi-section heating manner, so that the cost consumption in treatment can be reduced while the innocent treatment of the electrolytic manganese residues is realized, and the innocent treatment is more economical and efficient.
本发明属于锰渣处理技术领域，具体的说是电解锰渣无害化处理方法及其沥青路面再生骨料制备装置，所述处理方法包括如下步骤：步骤S1：提前对马弗炉进行温度控制，将马弗炉的温度控制在0℃，进而将原始锰渣投入马弗炉内部；步骤S2：对马弗炉内部进行升温，对原始锰渣进行煅烧，温控曲线为0‑800℃，升温速率为10℃/min；800℃保温60min；800‑1550℃，升温速率5℃/min；1550℃保温180min；步骤S3：将煅烧完毕后的锰渣成品，投入滚筒冷渣机中，对锰渣成品进行降温，使其冷却到室温；步骤S4：将冷却完毕后的锰渣成品投入粉碎机中。通过多段加热的方式，对电解锰渣进行无害化处理，在实现了对电解锰渣进行无害化处理的同时，可减少处理中的成本消耗，使得无害化处理更加经济高效。
