Title:
TREATMENT OF INCINERATION FLY ASH CONTAINING USED WASTE GAS TREATING AGENT
Document Type and Number:
Japanese Patent JPH11128876
Kind Code:
A
Abstract:
To treat incineration fly ash containing a waste gas treating agent where dioxins are adsorped by decomposing and removing dioxins polluting the environment.
A powder-type waste gas treating agent is blown to a waste as containing dioxins from an incineration furnace to adsorb dioxins to the waste gas treating agent. The waste gas treating agent where dioxins are adsorbed is collected by a dust collector. The incineration fly ash containing the waste gas treating agent collected by the dust collector is put into a cement kiln in which a cement clinker is calcined from a cement source material, and the dioxins adsorbed to the waste gas treating agent are thermally decomposed by the calcination heat during calcination of the clinker.
