Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention is provided at a kind of double membrane structure for repairing organic polluted soil
Reason system, including：
Double membrane structure greenhouse 1, it is the processing space 11 for being handled organic material contaminated soil inside it, processing
The outside in space 11 has folds the cushion formed by two membranes 12, and the cushion is connected with charging valve 13, by this
Charging valve 13 can be filled with hot gas into cushion, and the hot gas is filled in cushion, as canopy temperature and greatly
The buffer gas of the outer temperature of canopy, can avoid the direct contact of hot gas and the outer cold air of greenhouse in greenhouse and caused by dew condensation phenomenon；
Ventilating system, it is by being disposed on multiple air inlets of the side of double membrane structure greenhouse 1 by ventilation equipment 21
Mouth 22 provides hot blast to the processing space 11, and exhaust outlet 23, the exhaust outlet 23 are provided with the top in the processing space 11
It is connected by exhaust duct 24 with tail gas treating unit 3, valve for air exhaust 241 is provided with the exhaust duct 24；
Isolation cabin 4, it is arranged in the double membrane structure greenhouse 1, its one end passes through greenhouse logistics door 111 and the processing
Space 11 is connected, and the other end is connected by isolating logistics door 41 with the external world；The top of the isolation cabin 4 is provided with bleeding point
42, the bleeding point 42 is connected with one end of the pump-line 43 provided with air exhauster, and the other end of the pump-line 43 connects
Lead in the processing space 11；The isolation cabin 4 is additionally provided with the gas supplementing opening 44 for allowing extraneous gas unidirectionally to enter；
