Preferably, the order number 4-5 of described one-level screen cloth.
Preferably, the order number 20-30 of described secondary screen cloth.
Described second conveyer belt runs through described first reative cell and described second reative cell.
The beneficial effects of the utility model are:
The utility model carries out pretreatment to soil, reduces contaminated soil particle diameter, coordinates heating using microwave, dusty gas is discharged effectively from soil, and the dusty gas discharged is removed under the synergy of ultraviolet light and ozone.
Gas treatment chamber efficiently can remove stench, removes the major pollutants such as volatile organic matter, inorganic matter, hydrogen sulfide, ammonia, thio-alcohol; Effectively can also prevent secondary pollution, the dusty gas of escaping out when pretreatment collected by pipeline is set in soil screening teeter chamber, is evacuated in microwave heating system by vavuum pump and carry out subsequent treatment.
The utility model operating cost is low, without any mechanical action, noiselessness, without the need to personal management and regular maintenance, only need make regular check on, equipment energy consumption is low, and without the need to adding any material, as long as arrange corresponding exhaust duct and air draft power, making waste gas by the utility model decomposing, purifying, participating in chemical reaction without the need to adding other materials.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, a kind of device of high-efficiency photocatalysis oxidization process organic polluted soil, comprise the first reative cell 11 and the second reative cell 12, described second reative cell 12 connects filter 10;
The first conveyer belt 1, one-level screen cloth 2, agitator 3, secondary screen cloth 4 and the second conveyer belt 13 is set gradually from top to bottom in described first reative cell 11;
In described second reative cell 12, gas treatment chamber 14 and microwave generator 7 are set, ozone generator 8 and oxidative synthesis system 9 are set in described gas treatment chamber 14;
Described first reative cell 11 connects gas treatment chamber 14 by pipeline 5, and described pipeline 5 arranges blower fan 6.
Preferably, the order number 4-5 of described one-level screen cloth.
Preferably, the order number 20-30 of described secondary screen cloth.
Described second conveyer belt 13 runs through described first reative cell 11 and described second reative cell 12.
The operation principle of the present embodiment is as follows:
Soil is transported to one-level screen cloth 2 by the first conveyer belt 1, bulky stone filters out by one-level screen cloth 2, stirred by agitator 3 again, by the second conveyer belt, soil is transported to microwave generator 7 after again being fallen by contaminant filter by secondary screen cloth 4 again after being pulverized by stone larger for volume, through microwave disinfection, the residual gas of generation is sent to gas treatment chamber 14 by conduit.The gas produced in the first reative cell is sent to gas treatment chamber 14 by pipeline 5, through ozone generator and oxidative synthesis system, gas is resolved into carbon dioxide and water.
This technology is that the oxygen molecule utilizing high energy ultraviolet Line beam to decompose in air produces free oxygen, i.e. active oxygen, because negative ions entrained by free oxygen is uneven so need be combined with oxygen molecule, and then produces ozone.Organic Pollution material is converted into the simple inorganic matter such as carbon dioxide, water of nonhazardous by the highly active ion-oxygen (carboxyl free radical) that the oxidability of ozone and ozone produce under the irradiation of ultraviolet light, thus reaching the object of purifying exhaust air, this course of reaction is a kind of advanced oxidation processes under high energy ultraviolet beta radiation and ozone cooperative effect.
Ultraviolet light and the more independent ozone oxidation efficiency height of ozone cooperative effect are a lot, the decomposition of the irradiation meeting accelerate ozone of ultraviolet light, the oxidizing potential (2.07ev) of the ozone that the oxidizing potential (2.8ev) of living radical OH produced is more extremely strong than oxidisability is also high by 35%, therefore carboxyl free radical and organic reaction speed exceed several order of magnitude, and the reaction of carboxyl free radical to oxidize contaminants is non-selectivity, chain reaction can be caused, therefore organic pollution materials, stench can not only by ozone direct oxidation, and can be oxidized by the product carboxyl free radical of ozone decomposed, and the latter occupies an leading position under action of ultraviolet light.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
