Between outside have the cushion that is formed folded by two membranes, be filled with hot gas in the cushion;
Ventilating system, including ventilation equipment, it is disposed on multiple air inlets and the institute of the side of double membrane structure greenhouse
Ventilation equipment are stated to be connected.
The described double membrane structure processing system for repairing organic polluted soil, wherein:In the processing space
Top be provided with exhaust outlet, the exhaust outlet is connected by exhaust duct with tail gas treating unit.
The described double membrane structure processing system for repairing organic polluted soil, wherein:In the exhaust duct
It is provided with valve for air exhaust.
The described double membrane structure processing system for repairing organic polluted soil, wherein:In the duplicature knot
Isolation cabin is additionally provided with structure greenhouse, described isolation cabin one end is connected by greenhouse logistics door with the processing space, the other end
It is connected by isolating logistics door with the external world.
The described double membrane structure processing system for repairing organic polluted soil, wherein:The isolation cabin is provided with
Bleeding point, the bleeding point are connected with one end of the pump-line provided with air exhauster, the other end connection of the pump-line
Into the processing space.
The described double membrane structure processing system for repairing organic polluted soil, wherein:The isolation cabin is provided with
Allow the gas supplementing opening that extraneous gas unidirectionally enters.
The described double membrane structure processing system for repairing organic polluted soil, wherein:The two membranes are adopted
With Kynoar material.
The described double membrane structure processing system for repairing organic polluted soil, wherein:The multiple air inlet
Spacing be not more than 3 meters.
Compared with prior art, the invention has the advantages that:1. being filled in the hot gas in cushion, can make
For the buffer gas of temperature outside canopy temperature and greenhouse, can avoid the direct contact of hot gas and the outer cold air of greenhouse in greenhouse and
Caused by dew condensation phenomenon.2. moreover, being passed through hot-air in double membrane structure canopy, gas pressure in interlayer is on the one hand set to be more than in canopy
Gas, it can prevent that gas outwards volatilizees in canopy, another aspect double membrane structure can escape to pollutant and play double insurance
Effect.3. setting isolation cabin in logistics door, isolation cabin in confined conditions, dusty gas is drawn back to processing space, led to simultaneously
Cross tonifying Qi hole and supplement clean gas to isolation cabin, when opening greenhouse logistics door, can effectively avoid gas in canopy from escaping.

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;
Wherein, the two membranes 12 preferably use Kynoar (PVDF) material;Moreover, to ensure processing space 11
Interior hot gas is spread uniformly, and the spacing of the multiple air inlet 22 is not more than 3 meters.
Moreover, the inside earth's surface in double membrane structure greenhouse 1 is additionally provided with heating coil, certain thickness is covered on heating coil
Water-tight concrete layer, contaminated soil re-layed on the concrete layer, and the heat of heating coil is radiated by concrete layer
Conduction raises contaminated soil temperature, can promote the volatilization of moisture and pollutant in contaminated soil to contaminated soil.
Further, it is also possible to set whole slot type turner in the double membrane structure greenhouse 1, throwing is turned over for handle high humidity soil
Processing, can promote the volatilization of moisture and pollutant in contaminated soil.The moisture of southern high humidity contaminated soil is high, using one
As turner be difficult to handle, the present invention use whole slot type turner, it is possible to increase soil turns over throwing efficiency.
When the present invention uses, as shown in figure 4, the high humidity contaminated soil in double membrane structure greenhouse 1 is in heating coil
Or under the conditions of solar radiation, moisture and organic matter in contaminated soil volatilize and entered in canopy in gas, cause gas in canopy
Humidity improves;Tail gas treating unit 3 intermittently or continuously extracts high humidity dusty gas in canopy, high humidity dusty gas is passed through gas
Liquid/gas separator, after removing most of vapor, low temperature plasma is passed through again, to destroy organic pollution, finally reach tail gas
Mark discharge;Ventilation equipment 21 intermittently or continuously purge hot dry wind into greenhouse, on the one hand can prevent canopy inwall water dew from condensing,
On the other hand dusty gas can be promoted to be extracted greenhouse.
When needing vehicle etc. during soil treatment and being exported out of canopy, first open isolation cabin 4 and double membrane structure is big
The greenhouse logistics door 111 that canopy 1 connects, treat that vehicle enters in isolation cabin 4, close greenhouse logistics door 111, open the top of isolation cabin 4
Air exhauster, automatically turn on the sidepiece of isolation cabin 4 intake valve, dusty gas in isolation cabin 4 is back to double membrane structure greenhouse 1
It is interior, and supplement outside cleaned air;After automatic checkout equipment detection inner air in isolation cabin 4 is up to standard, isolation is automatically turned on
Logistics door 41, after vehicle output is outdoor, close isolation logistics door 41.
It is described above to be merely exemplary for the purpose of the present invention, and it is nonrestrictive, and those of ordinary skill in the art understand,
In the case where not departing from the spirit and scope that claim is limited, can many modifications may be made, change or equivalent, but will all fall
Enter within protection scope of the present invention.
