摘要:PROBLEM TO BE SOLVED: To provide a heat-cleaning apparatus for contaminated soil that can perform ideal heat-cleaning treatment of contaminated soil while saving energy.SOLUTION: A preheating kiln 12 for heating soil before cleaning with the potential heat of exhaust gas exhausted from a heating treatment kiln 1 for performing heat-cleaning treatment of contaminated soil is provided downstream of exhaust gas from the heating treatment kiln 1. The contaminated soil before cleaning is supplied to the preheating kiln 12 and heated with the potential heat of exhaust gas from the heating treatment kiln 1 to perform pretreatment for reducing the water content of the contaminated soil, and then the contaminated soil reduced in the water content is supplied to the heating treatment kiln 1 to perform heat-cleaning treatment.
