摘要
介绍了鞍钢联众焙烧法回收混合废酸的原理及工艺,通过对混酸再生技术的改进,使废酸及再生酸达到平衡,提高了再生酸硝酸回收率,降低了设备故障率,经济效益显著。
The principle and process of recycling waste mixed acid by roasting method in Ansteel LISCO Steel were introduced. Based on the improvement of the recycling technology for waste mixed acid, the balance between waste acid and recycled acid was achieved. By improving the recovery rate of HN03 in recycled acid, the failure rate of the recycling equipment was reduced and therefore the economic benefits were remarkable.
