PURPOSE: A purification apparatus for heavy metal contaminated soil is provided to improve soil purification efficiency by inputting the contaminated soil to a heating container for heat-decomposing minute heavy metals before discharging. CONSTITUTION: A purification apparatus for heavy metal contaminated soil comprises the following: a heating container(10) including plural plasma torches(20) connected to a plasma generator; inlet(11) installed on the upper side of the heating container while supplying the contaminated soil to cover the torches; an discharging outlet(12) including a discharge bucket(40) intermittently rotating by a motor from the lower side of the heating container; a exhaust pipe(13) included in the upper side of the heating container to exhaust gas generated from a thermal decomposition process in the inside of the heating container; and plural heating nozzles(14) spraying steam at high pressure and high temperature to the inside of the heating container. |
