The device that utilizes the microwave treatment contaminated soil of known technology covers at contaminated soil and processes apparatus and irradiating microwaves, and remove polluter by contaminated soil, No. 570845 (flat just hero etc. of TaiWan, China patent gazette Announcement Number such as bulletin on January 11st, 2004, the method for innocent treatment of contaminated soil and processing apparatus) the middle soil that will be subjected to the chemical contamination of boiling point below 500 ℃ that discloses, cover thereon and process apparatus, and the knife-edge that will process apparatus is embedded in more than the underground 1cm of contaminated soil, and have the pipe that is communicated with microwave catheter and exhaust gas treatment device at the opposition side of aforementioned peristome, with microwave irradiation contaminated soil surface to remove polluter.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of equipment that need not the microwave treatment of contaminated soil excavation is subjected to organic matter or mercury contaminated soil.
In order to reach above-mentioned purpose, the utility model provides a kind of microwave treatment to be subjected to the equipment of organic matter or mercury contaminated soil, includes:
Microwave rf generator, it places ground and produces microwave and the watt level of control launched microwave;
Waveguide, it is inserted in the contaminated soil and with tube connector with vertical mode and is connected with described microwave rf generator, can deeply adjust length according to contaminated soil, mainly microwave is imported in the contaminated soil, makes microwave directly act on contaminated soil;
Protective cover, its center of circle take the contact point on waveguide and ground as protective cover is positioned over ground, avoid microwave by the underground loss to ground.
Therefore, the utility model produces microwave via the waveguide of inserting in the contaminated soil with microwave rf generator, make contaminated soil be subjected to microwave action, make its thermal desorption or destruction be converted into carbon dioxide and water the heating of the organic matter in the soil, make organic matter removal to obtain clean soil; Mercury contaminated soil is subjected to microwave action, makes the mercury in the soil be subjected to the thermal desorption loss to leave soil to obtain clean soil.
Moreover the technical scheme that the utility model adopts is under the situation of not excavating contaminated soil, directly processes the equipment of contaminated soil at terrain, and it is all effective to VOCs-contaminated Soils or mercury contaminated soil.
As above, the utlity model has following beneficial effect:
1, the utility model microwave treatment is subjected to the equipment of organic matter or mercury contaminated soil, the microwave terrain is processed and to be subjected to the equipment of organic matter or mercury contaminated soil can be under the situation of not excavating contaminated soil, at short notice contaminated soil is processed into clean soil, it helps the regulation of contaminated soil site and protection water table not to be subjected to organic matter or mercury pollution, is beneficial to the utilization of follow-up soil and underground water;
2, the utility model microwave treatment is subjected to the equipment of organic matter or mercury contaminated soil, because the reaction time is short, therefore relative response device scale can significantly be dwindled, and because not excavating soil, need not the contaminated soil carrying is processed to factory, can significantly save the funds of founding the factory, tool mobility and avoid causing secondary pollution in transportation;
3, the utility model microwave treatment is subjected to the equipment of organic matter or mercury contaminated soil, because the utility model can will be subjected to the polluter of organic material contaminated soil to be converted into stable, harmless carbon dioxide and water at short time thermal desorption or destruction; Mercury contaminated soil is subjected to microwave action, make the mercury in the soil be subjected to the thermal desorption loss to leave soil to obtain clean soil, reaction temperature is low, processing is subjected to organic matter or mercury contaminated soil relatively with tradition incineration method, the spent energy significantly reduces, and do not produce the toxic polluters such as dioxin, polycyclic aromatic hydrocarbons (PAH) (PAHs), so unlikelyly cause secondary pollution.
