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, by the heat treatment of the fly ash generated in the waste incinerator to prevent fusion of the molten and hence the container of the chloride in accordance with the chloride contained in the fly ash in the removal of dioxins and heavy metals, efficient and economical removal of dioxins and heavy metals as a method and a device, to waste the fly ash discharged from incineration plants soil, waste concrete minutes lung cement minutes of mixing to be a total of 20 to 80% by weight of the weight of the mixture of a first species or first mixture of two or more selected from step 1 (S10) and; After filling the powder of the fly ash mixture is mixed in the first step with a height less than 10cm in a plurality of charged container, and the second stage 2 (S20) for charging the plurality of contents in the container is heated to; Within the heating furnace and the first stage 3 (S30) to volatilize the dioxins and heavy metals contained in the fly ash mixture by heating the fly ash mixture in the plurality of contents in the container 550 ~ 750 ℃; Including the step 4 (S40) to the volatile heavy metals, dioxins, and at the third step of discharging the furnace with the exhaust gas to the outside is characterized in that formed.
