摘　　要：简述了硫化渣产生的原因,分析了硫化渣的性质及硫化渣处理现状,全面比较了热风烘干、微波烘干及蒸汽烘干的原理、优缺点及经济指标,得出了蒸汽烘干更适合用来烘干硫化渣的结论。蒸汽烘干具有自动化程度高、运行环境好、生产成本低、温度易于控制等优点,但要有稳定的蒸汽来源。The causes of sulfidization slag were described;the properties and treatment status quo of sulfidization slag were analyzed;moreover,an all-round comparison was made among hot air drying,microwave drying and steam drying in terms of their principles,merits and demerits,and economic indicators.It's concluded that drying sulfidization slag with steam is the most suitable way.Steam drying has the advantages of high automation,good operation environment,low production cost and easy temperature control,but it needs stable steam source.
