Abstract

This application relates to a thermal desorption treatment process and repair device for organic polluted soil. The process of this application includes collecting polluted soil, pretreatment of the soil to be treated, thermal desorption of the pretreated soil, thermal desorption of soil and waste gas Steps such as separating and recovering the heat of exhaust gas and detecting thermally desorbed soil; the restoration device of the present application includes air extraction device, pretreatment device, thermal desorption rotary kiln and incineration device, and the air extraction device and pretreatment device are all connected with heat The desorption rotary kiln is connected, the thermal desorption rotary kiln is connected with a batch conveying assembly, the thermal desorption rotary kiln and the incineration device are connected with a heat exchange element for recovering gas heat, and the incineration device is connected with a Purification parts for purifying gases. The process of the present application can recover the heat of the discharged gas and use it to preheat the pretreated soil, saving energy and being more environmentally friendly; the device of the present application can reduce repeated treatment of qualified thermal desorption soil, recover heat, and reduce secondary pollution.

Description

technical field [0001] This application relates to the field of contaminated soil treatment technology, in particular to a thermal desorption treatment process and restoration device for organic polluted soil. Background technique [0002] In recent years, due to the discharge of pollutants such as industrial wastewater, a large amount of soil has been polluted. The polluted soil contains a large amount of harmful organic matter, which seriously affects the health of residents. Therefore, it is necessary to remediate the polluted soil. Thermal desorption treatment process can effectively remediate polluted soil, so it is widely used. [0003] The patent with the notification number CN106180169B in the related technology discloses a soil thermal desorption restoration process, including: crushing, screening and dehydration pretreatment of the soil to be repaired; transporting the soil to the thermal desorption rotary kiln in a closed environment The thermal desorption proces...
