电弧炉炼钢过程的二噁英及抑制措施

摘要

文章介绍了二噁英类的结构、毒性及理化性质，分析了电弧炉炼钢过程二噁英的产生机理，烟气中的二噁英主要通过从头合成（de novo）反应生成。介绍了我国电弧炉烟气中的二噁英排放情况，讨论了抑制二噁英生成的措施及烟气中二噁英的脱除措施。%This paper describes the structure, toxicity and physicochemical properties of dioxin,analyzes dioxin generation mechanism, which is formed by de novo synthesis reaction in Electric Arc Furnace. It investigates the dioxin emissions, inhibition of its generation and the preventive measures in Electric Arc Furnace in China.
