DECONTAMINATER AND DECONTAMINATION METHOD FOR THE POLLUTED SOIL BY OIL

摘要

An apparatus and a method for purifying oil-polluted soil are provided to volatilize oil from the soil by heating the oil-polluted soil, and remove harmful materials from the volatilized oil by reheating the volatilized oil at an ultra-high temperature, thereby preventing secondary environmental pollution. A soil input port(110) inputs oil-polluted soil into a heating case(120) therethrough. The heating case is connected to the soil input port, wherein the heating case has heating facilities for heating the soil. A discharge passage(130) is connected to the heating case to discharge the oil volatilized from the heating case. A connection passage(160) moves all of the soil discharged from the heating case. A cooling case(170) is connected to the connection passage, wherein the cooling case has cooling facilities for cooling the soil. A soil discharge port(140) is connected to the cooling case to discharge the soil within the cooling case therethrough. Further, a conveyor is additionally contained in order to transfer soil discharged to the soil input port.
