Title:
PRODUCTION OF CARBIDE FROM FLAMMABLE WASTE AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JP3530001
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing carbide from flammable wastes, capable of obtaining a clean carbide which has a high removal ratio of water-soluble substances from the flammable wastes and contains a very small amount of heavy metals and advantageous in developing a source-recycling system for wastes and effective uses thereof.
SOLUTION: This method comprises: heating flammable wastes under a lower oxygenic condition; subjecting the thus obtained carbide to wet crush; and dehydrating and drying it. This makes it possible to quickly remove water- soluble substances and heavy metals apt to remain in the carbide in a high efficiency and hence the resultant carbide is so refined as to contain scarcely any harmful substances of the water-soluble substances and heavy metals.
