<p><P>PROBLEM TO BE SOLVED: To provide an oil sludge treatment apparatus capable of efficiently treating oil sludge, which is produced in a vegetable oil manufacturing process, in a short time. <P>SOLUTION: The oil sludge treatment apparatus includes a reactor 20 for the oxidative decomposition treatment of oil sludge, an electric heating coil 23 for heating the water in the reactor 20 to 650°C higher than the critical temperature of the water, a high-pressure pump 13 for introducing the oil sludge in the reactor 20 and pressurizing the pressure of the water in the reactor 20 to 17 MPa below the critical pressure of the water, and a compressor 33 for supplying an oxidizing agent into the reactor 20 and pressurizing the pressure of the water in the reactor 20 to 17 MPa below the critical pressure of the water. An exhaust pipe 41 for discharging the reaction gas produced by the oxidation decomposition treatment of the oil sludge and a waste pipe 51 for discharging the solid (inorganic) residue produced by the oxidation decomposition treatment are connected to the reactor 20. Further, a gas-liquid separator 44 for separating the reaction gas into a gaseous substance and a liquid substance is connected to the exhaust pipe 41. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
