Ex-situ soil thermal desorption repair equipment

The utility model relates to ex-situ soil thermal desorption repair equipment. The ex-situ soil thermal desorption repair equipment comprises a construction platform for stacking a to-be-treated contaminated soil pile and a heat preservation layer paved at the top of the to-be-treated contaminated soil pile, the construction platform is sequentially provided with a concrete layer, a heat insulation layer, a water filtering layer and geotechnical cloth from bottom to top, a water collecting cavity is formed in the water filtering layer, and a submersible pump used for draining water is arrangedin the water collecting cavity. An impermeable film is laid on the heat preservation layer; and a water pumping pipe, a heating pipe and an air pumping pipe which are inserted into the to-be-treatedpolluted soil pile are further arranged. The thermal desorption device has the beneficial effects that the contaminated soil treatment capacity is large, the thermal desorption efficiency is high, theequipment is convenient to
