Problems solved by technology
Indirect thermal desorption has the disadvantages of small processing capacity and high requirements for raw material pretreatment. Compared with indirect thermal desorption, direct thermal desorption has high heat transfer efficiency and large processing capacity, but the thermal desorption produced by direct thermal desorption The air volume is large and the content of particulate matter is high

The embodiment of the invention provides a treatment method and a treatment device for organic contaminated soil, and the treatment method for the organic contaminated soil comprises the following steps: carrying out thermal desorption treatment on the organic contaminated soil to form a solid-phase material and flue gas; adopting a heat accumulating type combustion furnace to treat the flue gas and store heat, and adopting the stored heat to preheat the subsequent flue gas, so that the volatile organic compounds in the organic contaminated soil can be subjected to harmless treatment by adopting the treatment method for the organic contaminated soil; the heat generated by combustion in a combustion chamber can be recycled, and the formation of dioxin can be prevented by adopting the heat accumulating type combustion furnace to quickly cool the flue gas.
Description
technical field [0001] Embodiments of the present disclosure relate to an apparatus and method for treating organically polluted soil. Background technique [0002] For organic polluted soil, thermal desorption technology has a significant effect, and thermal desorption technology is widely used in the remediation of organic polluted soil. Thermal desorption technology is also called thermal desorption technology. As a non-combustion technology, thermal desorption technology has a wide range of pollutant treatment, movable treatment equipment, and reusable soil after restoration, especially for chlorine-containing organic compounds. , non-oxidative combustion treatment can avoid the production of dioxins, which is widely used in the remediation of organic contaminated soil. At present, according to the classification of heating methods, thermal desorption technologies are usually divided into two categories: direct thermal desorption and indirect thermal desorption. Indire...
