Title:
METHOD FOR DETOXIFYING INCINERATION ASH OR THE LIKE AT HIGH TEMPERATURE
Document Type and Number:
Japanese Patent JP3867125
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a treatment method for detoxifying incineration ash or the like capable of heating fly ash at 400°C or above without fixing the same to decompose dioxins and capable of evaporating heavy metals in fly ash as chlorides to remove them.
SOLUTION: Mullite (2Al2O3-SiO2) is mixed with fly ash containing a harmful organochlorine compound and the resulting mixture is heated at 400°C or above, preferably 600°C or above, ideally 700°C or above to detoxify the fly ash. When the mixture of the fly ash and mullite is heated, the fly ash is held to a powdery state even at 400°C or above without being fixed.
