The method and apparatus for removal of dioxins/furans and heavy metals in the fly ash formed from wastes incinerator

摘要

The present invention removes dioxins and heavy metals in the fly ash treated by heating the fly ash generated from waste incinerators, This prevents melting and fusing of the vessel in accordance with the chloride contained in the chloride, heavy metals and dioxin relates to a method and apparatus for efficiently and economically removed, the fly ash discharged from waste incineration plants the soil, waste concrete minutes a first step (S10) of mixing the mixture of the selected one or one or more closed-cement mixture from a minute to be 20 to 80% by weight of the total weight; After filling the mixed powder of the fly ash mixture in the first step with a height of less than 10cm, each container of a plurality of contents, and the second step (S20) are charged to the furnace that a plurality of charging the vessel; A third step (S30) and to volatilize the dioxins and heavy metals contained in the fly ash, the fly ash in the mixture by heating the mixture charged in the plurality of containers to 550 ~ 750 in the heat; Characterized by comprising a fourth step (S40) for discharging to the outside of dioxins and heavy metals volatilized in the third step in the furnace with the exhaust gases.
