Abstract

The invention discloses a contaminated soil thermal desorption remediation system and method. The contaminated soil thermal desorption remediation system comprises a contaminated soil thermal desorption device and a tail gas treatment system, wherein the tail gas treatment system is connected with a tail gas exhaust port of the contaminated soil thermal desorption device. The tail gas treatment system comprises a steam filter, a primary condensing device, a vacuum generator, a secondary condensing device, an activated carbon filter and a gas exhaust device which are connected in sequence. Thesystem and the method can significantly reduce the operation energy consumption and repair cost of the system, significantly reduce the maintenance frequency of the system, maintain the safe and stable continuous operation of the system, and improve the thermal desorption effect of the contaminated soil.

Description

technical field [0001] The present application relates to the technical field of soil remediation, in particular to a thermal desorption remediation system and method for polluted soil. Background technique [0002] At present, most of the organically polluted soils that are remediated in situ are treated by thermal desorption technology. The thermal desorption remediation technology heats the contaminated soil to a sufficient temperature through direct heating or indirect heating, so that the organic pollutants contained in it can be recovered. The process of volatilization or separation. [0003] When performing thermal desorption on oil-contaminated soil, the tail gas treatment system of the existing thermal desorption remediation system has an unreasonable structural design. Generally, there is no material (oil) recovery device or the quality of the recovered material (oil) is poor, resulting in environmental pollution. Secondary pollution, pollutant treatment is not th...
