Abstract:
Embodiments of the present invention relate to a thermal desorption system for oil-contaminated soil and gravel, using a microwave indirect irradiation method and including a microwave emission prevention device and a preheating device using waste heat, and a thermal desorption method for oil-contaminated soil and gravel, using the same and, more specifically to: a device capable of economically purifying, in an eco-friendly manner, contaminated soil and gravel by using a microwave indirect irradiation method on soil and gravel contaminated by pollutants such as various oils or organic waste; and a method therefor. When using the contaminated soil and gravel purification device and the method therefor of the present invention, purification work can be completed by processing contaminated soil and gravel only once, thereby enabling high productivity to be ensured, and waste materials discharged from an ironmaking process and the like are used as raw materials of heating element particles such that objectives are achieved even without using conventional, high-priced materials, thereby enabling high economic feasibility to be ensured, and thus applicability to an actual field can remarkably increase. In addition, an outer tube encompassing an inner tube extends to both sides and a plurality of ring-shaped microwave attenuation units are arranged on the inner circumferential surface of the outer tube, such that microwaves are prevented from leaking between the inner tube and the outer tube, thereby enabling eco-friendliness to be ensured, and even the waste heat generated during a pollutant desorption process is utilized in the system itself, thereby enabling economic feasibility to increase further.

Claim (Index 1):
An oil-contaminated soil and gravel thermal desorption system using a microwave indirect irradiation method comprising:\n a storage part in which contaminated soil and gravel are stored; a conveying part configured to introduce the contaminated soil and gravel of the storage part into a contaminant desorbing part; the contaminant desorbing part configured to desorb contaminants from the contaminated soil and gravel conveyed by the conveying part by heat, including an inlet through which the contaminated soil and gravel are introduced, a treatment section in which the contaminated soil and gravel are subjected to thermal desorption treatment, and an outlet through which the soil and gravel subjected to the thermal desorption treatment are discharged, wherein a single or a plurality of microwave oscillating parts are connected to one side of the treatment section, the contaminant desorbing part includes an outer tube that constitutes a cylindrical fixed container and an inner tube that is formed in a cylindrical shape having a smaller diameter than the outer tube and rotatably disposed inside the outer tube by a rotation shaft and into which the contaminated soil and gravel are introduced through the inlet, a driving motor to which the rotation shaft is extended and connected is provided outside of the outer tube, an outer circumferential surface of the inner tube is provided with a microwave absorbing and heat generating element for absorbing microwaves to generate heat, a cavity space for reflecting microwaves is provided between the outer tube and the inner tube, and the microwaves irradiated from the microwave oscillating part generate irregular reflection in the cavity space so that heat is generated in the microwave absorbing and heat generating element provided on the outer circumferential surface of the inner tube, thereby thermally desorbing contaminants from the contaminated soil and gravel inside the inner tube; and a retrieving part configured to retrieve soil and gravel from which the contaminants have been removed through the contaminant desorbing part, wherein the contaminant desorbing part comprises portions extended from opposite ends of the outer tube and a plurality of microwave attenuating members each of which has a hook shape bent twice in a center direction of the contaminant desorbing part along inner circumferential surfaces of the extended portions of the outer tube.
