Electric arc furnace device for reduction modification treatment of hot steel slag
The electric arc furnace device comprises an electric arc furnace body, the top of the electric arc furnace body is provided with an auxiliary feeding furnace body, a refractory protective sleeve and a furnace top dry ash blowing pipe, and the lower portion of a furnace cavity of the auxiliary feeding furnace body communicates with the upper portion of a furnace cavity of the electric arc furnace body; a high-temperature flue gas discharge port is formed in the upper portion of a furnace cavity of the auxiliary feeding furnace body and connected with a powder collecting system through a high-temperature flue gas pipeline, the auxiliary feeding furnace body is provided with a feeding port, the refractory protective sleeve is provided with a central oxygen-enriched injection pipe and an electrode hole, the graphite electrode is arranged in the electrode hole, and an electrode injection hole is formed in the center of the graphite electrode. The electrode injection holes are connected with a pulverized coal injection system through electrode pulverized coal injection pipes, and the furnace top dry ash injection pipe is connected with a dry ash injection system. According to the electric arc furnace device, iron can be reduced from steel slag, zinc-containing fly ash can be sprayed into the reduction molten pool, dezincification treatment is conducted on the zinc-containing fly ash in the reducing atmosphere, and finally zinc oxide powder is recycled through the powder collecting system.
本发明公开了一种用于热态钢渣还原改性处理的电弧炉装置，包括电弧炉本体，电弧炉本体的顶部设有辅助加料炉体、耐材保护套、炉顶干灰喷吹管，辅助加料炉体的炉腔下部与电弧炉本体的炉腔上部连通，辅助加料炉体的炉腔上部设高温烟气排放口，高温烟气排放口通过高温烟气管道与收粉系统连接，辅助加料炉体设有加料口，耐材保护套设有中心富氧喷吹管和电极孔，石墨电极设置在电极孔内，石墨电极中心设有电极喷吹孔，电极喷吹孔通过电极煤粉喷吹管连接煤粉喷吹系统，炉顶干灰喷吹管连接干灰喷吹系统。该电弧炉装置可将铁从钢渣中还原，并可将含锌除尘灰喷入还原熔池，在还原气氛下对含锌除尘灰脱锌处理，最终通过收粉系统回收氧化锌粉末。
