METHOD FOR SUPPRESSING RESYNTHESIS OF DIOXINS AND USE OF ACID CLAY OR ACTIVATED ACID CLAY AS SUPPRESSANT FOR RESYNTHESIS OF DIOXINS

摘要

PROBLEM TO BE SOLVED: To provide a method for suppressing resynthesis of dioxins in fly ash separated from a discharged gas, and to provide a new use of acid clay or activated acid clay as suppressant for resynthesis of dioxins.;SOLUTION: In the method for treating fly ash where molten fly ash contained in a discharged gas generated from a molten furnace or incinerated fly ash contained in a discharged gas generated from an incineration furnace is separated and eliminated by a dust collector, acid clay or activated acid clay is added to the front step or inside of the dust collector to suppress resynthesis of dioxins in the fly ash separated by the dust collector. The use of acid clay or activated acid clay as a suppressant for resynthesis of dioxins is also provided.;COPYRIGHT: (C)2013,JPO&INPIT
