Title:
THERMAL DESORPTION SYSTEM FOR POLLUTED SOIL AND BALLAST, USING MICROWAVE INDIRECT-IRRADIATION METHOD, AND THERMAL DESORPTION METHOD FOR POLLUTED SOIL AND BALLAST, USING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/186242
Kind Code:
A1
Abstract:
The present invention relates to a thermal desorption system for polluted soil and ballast, using a microwave indirect-irradiation method, and a thermal desorption method for polluted soil and ballast, using the system. More specifically, provided are an apparatus and a method capable of economically purifying polluted soil and ballast, which are polluted by pollution sources such as various oils or organic wastes, by using a microwave indirect-irradiation method. The thermal desorption system, used in the present invention, for the polluted soil and ballast, using the microwave indirect-irradiation method, improves the structure of a contaminant desorption part, to which contaminants are thermally desorbed, such that the contaminant desorption part comprises an outer container and an inner container, is provided to allow the polluted soil and ballast to pass through the inside of the inner container, and has a microwave-absorbing and heating element provided on the outer peripheral surface of the inner container, so as to irradiate the microwave-absorbing and heating element with microwaves, thereby thermally desorbing the contaminants of the polluted soil and ballast inside the inner container. Economic efficiency is ensured by using, as the microwave-absorbing and heating element, a material having both relatively low costs and excellent heat-generation efficiency and, simultaneously, applicability at the actual site can be enhanced, by generating low-temperature and high-temperature heat so as to enable sufficient thermal desorption regardless of the types of oils.
