摘要: 熔融工藝是目前處理工業粉塵及飛灰的有效方法.為了能夠有效控制熔融工藝中Zn、Pb等重金屬資源的分離回收,對比分析了Zn、Pb在含Cl的FeO-CaO-SiO₂-Al₂O₃-Fe₂O₃渣系中的揮發行為.首先通過熱力學計算分析了Zn、Pb在該渣系中可能的揮發氣體種類,以及各因子如溫度、熔渣成分、氧勢和Cl含量等的影響.同時,對以上問題進行了實驗研究.最終明確了分別提高Zn、Pb揮發分離效率的不同的技術措施和優化參數.

Abstract: Smelting process is an effective way to treat industrial dust and fly ashes nowadays.In order to effectively control the remove and recovery of heavy metals such as Zn,Pb by smelting process,the vaporization behaviors from FeO-CaO-SiO₂-Al₂O₃-Fe₂O₃ slag system with Cl were analyzed and compared in this study.Firstly,thermodynamic prediction on the possible vapor species of Zn and Pb in molten slag was carried out,together with the effect of some factors such as temperature,slag compositions and oxygen potential.And then related experimental study was performed.Finally the various technical measures and optimized parameters for enhancing the volatile efficiency of zinc and lead were determined.
