摘　　要：分析了现代垃圾焚烧厂二恶英的产生原理,从全厂角度提出控制烟气中二恶英含量的方法,即通过采取入炉前预处理、3T+E分解(燃烧温度不低于850℃、气体的停留时间不小于2 s、湍流强化燃烧、控制氧量)、炉外低温合成控制(控制二恶英的再生区间、防止受热面积灰)和末端排放控制(活性炭吸附、SCR)等方式,减少二恶英的产生,实现焚烧的二恶英控制。The principle of dioxin production in modern domestic waste incineration plant was analysed.The method of controlling dioxin content in flue gas has been put forward from the perspective of whole factory.By adopting the ways of pretreatment before charging,3T+E decomposition(combustion temperature is not lower than 850℃,gas residence time is not less than 2 s,strengthen turbulent combustion,control oxygen content),low temperature synthesis control outside the furnace(control regeneration interval of dioxins,prevent ash accumulation from heating surface)and terminal emission control(such as activated carbon adsorption,SCR)to reduce the generation of dioxin and achieve the control of burning dioxins.
