The invention provides a comprehensive
recovery technology of
solid waste gas ash and
zinc-containing ferrovanadium
slag. By combining advantages of low
iron content and rich carbon of gas ash and characteristics of high
iron content and rich precious metals of ferrovanadium
slag, and by the adoption of a rotary-
kiln fire method fuming enrichment technology, the material undergoes comprehensive
recovery. Advanced equipment such as a
waste heat boiler, a negative-pressure bag collector, a pneumatic emulsification desulfurization
tower and the like are configured to carry out efficient
recovery and harmless environmental-protection
processing of
flue gas so as to achieve the purpose of clean production. By a
beneficiation combined method, iron-containing
kiln slag undergoes high added-value exploitation. Thus, the
environmental protection problem of resource disposition is solved, and the effect of comprehensive utilization with low
energy consumption, high yield and high added-value is achieved. Problems of short
kiln age,
high energy consumption and low concentration of SO2 during the treating process of ferrovanadium slag can be solved by the technology provided by the invention, and problems of poor iron separation effect and overhigh content of
fluorine and
chlorine in
zinc hypoxide also can be solved. The technology has good economic benefit and high popularization and practical value.
