焚烧烟气中二噁英类控制技术研究进展

Advance on Dioxins Control Methods in Waste Incineration Plant

焚烧烟气中二噁英是制约垃圾焚烧技术发展的关键性问题。文章描述了烟气中二噁英的形态分布,并综述了烟气中二噁英控制技术的研究进展,指出了有待进一步研究的问题;重点阐述了活性炭吸附技术,比较了传统的利用活性碳吸附技术的净化工艺与双层滤料颗粒床+活性炭+布袋除尘脱酸除二噁英一体化新工艺。

Dioxins in flue gas are key issues which restrict the development of municipal solid waste incineration technology.Distribution features of dioxins in flue gas were described,and advances in dioxins control methods were reviewed,of which the problems to be further studied were pointed out.Adsorption technology of activated carbon was underlined,and traditional purification process using activated carbon and novel integrative technology of dual-layered granular bed ＋ activated carbon ＋ bag filter were compared.
