Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the present invention provides a kind of high humidity contaminated soil processing system, including:
Double membrane structure normal temperature desorbs greenhouse 1, is the processing sky for being handled organic material contaminated soil inside it Between 11, the outside in processing space 11, which has, by two membranes 12 folds the cushion formed, and the cushion is connected with charging valve 13, hot gas can be filled with into cushion by the charging valve 13, the hot gas is filled in cushion, as in greenhouse The buffer gas of the outer temperature of temperature and greenhouse, can avoid the direct contact of hot gas and the outer cold air of greenhouse in greenhouse and caused by knot Reveal phenomenon;Moreover, the gas pressure in cushion is more than the gas pressure in processing space, can prevent from handling the gas in space Body is outwards volatilized, and pollutant is escaped and plays double insurance effect.Wherein, the two membranes 12 preferably use Kynoar (PVDF) material;Moreover, to ensure that hot gas is spread uniform in processing space 11, the spacing of the multiple air inlet 22 is not more than 3 Rice.
Ventilating system, it is the side for desorbing greenhouse 1 by being disposed on double membrane structure normal temperature by ventilation equipment 21 Multiple air inlets 22 provide air quantity to the processing space 11, promote high humidity antecedent soil moisture in canopy, in the processing space 11 Top is provided with exhaust outlet 23, and the exhaust outlet 23 is connected by exhaust duct 24 with tail gas extraction system 3, in the exhaust duct Road 24 is provided with valve for air exhaust 241.Wherein, ventilation equipment 21 can be different according to two season of summer in winter temperature, and hot air unit is respectively adopted Or dry wind unit air blast into double membrane structure normal temperature desorption greenhouse 1.In the winter time, in double membrane structure normal temperature desorption greenhouse 1 Temperature is low, therefore hot blast is passed through into canopy using hot air unit, promotes pollutant in soil and water to be volatized into gas phase;In summer, Temperature is high in double membrane structure normal temperature desorption greenhouse 1 and atmospheric water content is big, therefore uses dry with air-conditioning dehumidifier principle Dry wind unit blasts dry wind into canopy, measurement of moisture content of gas in double membrane structure normal temperature desorption greenhouse 1 is reduced, in favor of organic Thing volatilizees.
Gas-liquid separator (is unillustrated), is connected with the downstream of the tail gas extraction system, to remove most of vapor;
Low temperature plasma equipment, it is connected with the gas passage in the gas-liquid separator downstream, to destroy organic pollution, Finally make tail gas qualified discharge.
In addition, the present invention also has isolation cabin 4, it is arranged in the double membrane structure normal temperature desorption greenhouse 1, its one end It is connected by greenhouse logistics door 111 with the processing space 11, the other end is connected by isolating logistics door 41 with the external world;Institute The top for stating isolation cabin 4 is provided with bleeding point 42, and the bleeding point 42 is connected with one end of the pump-line 43 provided with air exhauster, The other end of the pump-line 43 is communicated in the processing space 11;The isolation cabin 4, which is additionally provided with, allows extraneous gas list To the automatic compensating air valve 44 of entrance;
Moreover, the inside earth's surface in double membrane structure normal temperature desorption greenhouse 1 is additionally provided with heating coil (being unillustrated), heat Certain thickness water-tight concrete layer is covered on coil pipe, contaminated soil is re-layed on the concrete layer, the heat of heating coil Amount to contaminated soil, raises contaminated soil temperature by concrete layer conduct radiation, can promote in contaminated soil moisture and The volatilization of pollutant.
Further, it is also possible to whole slot type turner is set in double membrane structure normal temperature desorption greenhouse 1, for handling high wet soil Earth turns over throwing processing, can promote the volatilization of moisture and pollutant in contaminated soil.The moisture of southern high humidity contaminated soil Height, it is difficult to handle using general turner, the present invention uses 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 normal temperature desorption greenhouse 1 exists Under the conditions of heating coil or solar radiation, moisture and organic matter in contaminated soil volatilize and entered in canopy in gas, cause Gas humidity improves in canopy;Tail gas extraction system 3 intermittently or continuously extracts high humidity dusty gas in canopy, makes high humidity contamination gas Body is passed through gas-liquid separator, after removing most of vapor, enters low temperature plasma equipment again, to destroy organic pollution, Finally make tail gas qualified discharge;The intermittently or continuously purge air quantity into greenhouse of ventilation equipment 21, on the one hand can be prevented in canopy Wall water dew condenses, and 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 normal The greenhouse logistics door 111 that temperature desorption greenhouse 1 connects, treats that vehicle enters in isolation cabin 4, closes greenhouse logistics door 111, open isolation The air exhauster on the top of storehouse 4, the intake valve of the sidepiece of isolation cabin 4 is automatically turned on, dusty gas in isolation cabin 4 is back to duplicature knot In structure normal temperature desorption greenhouse 1, and supplement outside cleaned air;It is up to standard through automatic checkout equipment detection inner air in isolation cabin 4 Afterwards, isolation logistics door 41 is automatically turned on, after vehicle output is outdoor, closes 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.
