Embodiment 1

[0036] like Figure 1~2 As shown, the contaminated soil thermal desorption and desorption restoration equipment includes a pretreatment unit, a thermal desorption and desorption treatment unit, a gas phase product treatment unit, and a liquid phase product treatment unit;

[0037] The pretreatment unit includes a pretreatment device 91. The contaminated soil is first separated from large foreign matter in the pretreatment device 91, and then enters the thermal desorption and desorption treatment unit through the transfer bin 92;

[0038] The thermal desorption and desorption treatment unit is a thermal desorption and desorption furnace 1. The thermal desorption and desorption furnace 1 includes a material layer and a heating layer. The material layer is provided with a soil conveying system 11. The contaminated soil is thermally desorbed in the material layer. The material layer is provided with a heating system. The pyrolysis gas outlet 12 derived from the degassing, the soil...

Abstract

The invention relates to a polluted soil pyrolysis desorption repairing device and method. The polluted soil pyrolysis desorption repairing device comprises a pyrolysis desorption treating unit, a gaseous product treating unit and a liquid product treating unit. The pyrolysis desorption treating unit is a pyrolysis desorption furnace, the gaseous product treating unit comprises a combustion chamber, a flue gas dedusting unit, a spraying unit and a flue gas discharging port, and the combustion chamber, a heating layer of the pyrolysis desorption furnace, the flue gas dedusting unit and the spraying unit form a circular loop through a flue; and the liquid product treating unit is used for treating a gaseous product obtained after pyrolysis gas passes through a three-phase separating unit. The polluted soil pyrolysis desorption repairing device and method are good in treating effect, coking does not easily occur, and secondary pollution is not generated.

Description

technical field [0001] The invention belongs to the technical field of regeneration of polluted soil, and in particular relates to a thermal desorption and desorption restoration equipment and method for polluted soil. Background technique [0002] Contaminated soil refers to the quantity and speed of toxic and harmful pollutants entering the soil through various channels exceeding the capacity and purification speed of the soil, causing changes in the physical, chemical and biological properties, composition and properties of the soil, destroying the The natural dynamic balance of the soil is disrupted, resulting in soil natural dysfunction, deterioration of soil quality, impact on crop growth and development, decline in product yield and quality, resulting in certain environmental effects (secondary pollution of water bodies or the atmosphere), and can be passed through The food chain poses a hazard to living things and humans. After toxic and harmful pollutants enter the...
