Abstract
PURPOSE: Various kinds of sludges are dried, crashed and the organic components is converted in a high-temperature furnace into gas fuels and the inorganic components into melted slugs.
CONSTITUTION: A variety of sludge A as municipal wastes, sludges containing organic substance are incorporated with 10W20%, based on the sludge A, of a substance containing calcium as slaked lime as an agent facilitating filtration and dewatering and lowering the melting point, then filtered and dewatered in water remover B. The dewatered cake is led by conveyor 1 to dryer 2 where it is dried to less than 5% water content and crashed with crasher 13. The crashed powder is sent through storage tank 3 and controlled in quantity by calculator 7 and sent by conveyor 6 into melting furnace C. At the same time the oxygen gas that contains pure oxygen from oxygen generator 14 and has 21% or higher oxygen concentration is sent at a flow rate of 0.3W0.7 to the theoretical amount of required oxygen from burner 8 together with the dried sludge powder into the furnace C, whereby the organic components are converted into gas fuels and the inorganic components are melted and taken out of outlet 12 into vessel 20 and solidified.
