Title: Method and apparatus for treating oil-containing sludge
Inventor: ISHINO HIDETO
IPC: F23G7/04
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To prevent oxidation of iron content as main constituent of sludge to be treated and to effectively utilize it by regulating oxygen concentration in a furnace to a predetermined concentration, burning oil content of oil- containing sludge to completely remove the oil content, and cooling it under the condition of non-oxidation. SOLUTION: Oil-containing sludge is preferably supplied to a rotary kiln 3 of a parallel flow type rotary kiln combustion furnace via an oil-containing sludge inlet 5. Oxygen concentration in the kiln 3 is regulated to 0.5 to 15vol.%, and an inner wall temperature of the kiln 3 is held at 400 deg.C or higher. Moisture in the sludge thrown in the furnace is rapidly evaporated, the oil content in the sludge is rapidly volatilized, ignited and burnt. Only the oil content is completely burnt, and oxidation of the iron content is limited as much as possible. Thus, the sludge after the oil content is burnt is separated from gas in an area of an exhaust gas hood 7, and introduced into a rotary cooler 8. Since inert gas atmosphere exists in the cooler 8, oxidation of the iron content is prevented.
