Soil leaching, upgrading and remediating device with tail gas treatment function

The invention relates to the field of environmental protection, and discloses a soil leaching, upgrading and remediating device with a tail gas treatment function. A thermal analysis system comprisesa combustion chamber, an analysis chamber and a water storage tank; a heat exchange tube which is wound in the combustion chamber is connected to the water storage tank; one end, far away from the water storage tank, of the heat exchange tube communicates with the analysis chamber; a recovery pipe is arranged at the top of the analysis chamber; the recovery pipe is connected with a spraying tower;the top of the spraying tower is connected with an activated carbon adsorption tower; the bottom of the spraying tower is connected with a collecting pipe; and the collecting pipe is connected with the activated carbon adsorption tower. Through arrangement of the spraying tower and a water return pipe, high-temperature gas generated in the analysis chamber is liquefied by the spraying tower, andthen harmful substances are
