摘　　要：2019年10月投产的湖南某企业铅电解改造及稀贵综合回收项目,设计电解系统年处理粗铅10万t,综合回收系统选用一台2 m^(2)圆形竖式侧吹还原炉,用于处理粗铅电解产生的阳极泥及部分外购阳极泥,阳极泥规模年处理约为6000 t。该项目是中国恩菲专利SSC技术(侧吹浸没燃烧熔池熔炼)在稀贵领域的一次拓展,2 m^(2)圆形竖式侧吹还原炉的设计及应用取得了处理量大、能耗低、成本低、环保好等实际效果。本文对该炉的设计情况进行了介绍,并结合生产运行对一些问题进行了分析和探讨。A project of lead electrolytic transformation and comprehensive recovery of rare,precious metals of a Hunan enterprise was put into operation in October 2019.The designed electrolysis system treats 100000 t of crude lead per year,and the comprehensive recovery system adopts a 2 m^(2)circular vertical side-blowing reduction furnace to treat 6000 t/a anode slime generated from crude lead electrolysis and partially from outsourcing.This project is an extension of China ENFI’s patented SSC(Side-blowing Submerged Combustion Bath Smelting)technology in the field of rare and precious metal recovery.The design and application of the 2 m^(2) circular vertical side-blowing reduction furnace have yielded practical results of large processing capacity,low energy consumption,low cost,and environmental friendliness.This paper presents the design of the furnace and analyzes and discusses some issues in the context of its production operation.
