METHOD FOR TREATING DIOXIN-CONTAINING DUST TREATING DEVICE THEREFOR

摘要

PURPOSE:To provide a method for treating-dioxin-containing dust occurring in production of a cement-based solidifying material using ash of municipal wastes as a raw material and to supply a treating device therefor. CONSTITUTION:In returning dioxin-containing dust collected by a dust collector in production of a cement-based solidifying material using ash of municipal wastes as a raw material to a raw material for the cement-based solidifying material, the dust is partially returned from the vicinity of a burner to a burning furnace and heated to >=1,000 deg.C to thermally decompose dioxin in the dust rapidly in the burning furnace.
