Research on water leaching dechlorination of zinc-containing steel dust sludge

  • 摘要: 含锌钢铁尘泥是钢铁冶炼过程中产生的副产物,含有大量Cl以及Fe、Zn、K、Na等元素。含锌钢铁尘泥在返回钢铁生产流程中,Cl会在循环过程富集,直接导致烧结过程不稳定,同时严重腐蚀高炉内衬。开展了含锌钢铁尘泥中氯的水洗脱除研究,结果表明:在液固比5 mL/g、浸出温度70 ℃、浸出时间60 min、转速160 r/min条件下,含锌钢铁尘泥中Cl的浸出率达到87%;此外,在液固比为6 mL/g,常温下,三级逆流水洗45 min,含锌钢铁尘泥中Cl的浸出率超过90%。同时,水洗过程在一定程度能降低含锌钢铁尘泥中金属的浸出毒性。研究成果可为含锌钢铁尘泥中Cl的去除提供理论与技术支撑。
