Abstract

The invention relates to a thermal desorption treatment process and a remediation device for organic contaminated soil. The process comprises the steps of collecting the contaminated soil, pretreating the soil to be treated, performing thermal desorption treatment on the pretreated soil, separating the thermal desorption soil from waste gas, recycling heat of the waste gas, detecting the thermal desorption soil and the like. The repairing device comprises an air extracting device, a pretreatment device, a thermal desorption rotary kiln and an incineration device, wherein the air extracting device and the pretreatment device are both connected with the thermal desorption rotary kiln, the thermal desorption rotary kiln is connected with a batch conveying assembly, a heat exchange piece used for recovering gas heat is connected between the thermal desorption rotary kiln and the incineration device, and the incineration device is connected with a purification piece used for purifying gas. According to the technology, heat of exhausted gas can be recycled and used for preheating and pretreating soil, energy is saved, and the technology is more environmentally friendly; and according to the device, qualified thermal desorption soil subjected to repeated treatment can be reduced, heat is recovered, and secondary pollution is reduced.

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...
