Title:
有機性廃棄物の溶融分留装置
Document Type and Number:
Japanese Patent JP4817569
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To use an organic sludge as a recycled resource having a product value by rendering a molten slag nontoxic and homogeneous, reclaiming metals contained therein, and reducing processing costs through the recovery of heat during the process of melting wastes including an organic matter (combustible part). SOLUTION: A slag containing no heavy metal is manufactured by the evaporation of heavy metal compounds from a molten slag, and the heavy metal compounds are separated and recycled by promoting positive migration of the heavy metal compounds to a gaseous phase, and fractionating them. Industrial waste containing dry pulverized organic matter is combusted in a low temperature melting furnace and incombustible parts are melted and introduced to a high temperature melting furnace. Gases generated in the furnaces are introduced into a high temperature dust collector to recycle high boiling point dust containing high boiling point metallic compounds. Emissions passed through a high temperature dust collection chamber are cooled and introduced into a low temperature dust collector to recycle low boiling point dust containing low boiling point metallic compounds. The cooling is effected by a heat storage type heat exchanger in order to increase efficiency through heat recovery.
