Abstract

The invention relates to the field of environment engineering, and concretely relates to an in-situ fuel gas thermal desorption apparatus for soil remediation treatment. The apparatus comprises a thermal conduction device, an extraction device, a treatment device and a control device; the thermal conduction device is used for heating a target repairing in a thermal conduction manner to raise the temperature of soil to a target temperature; the thermal conduction device includes a heating well, a combustion fan, a burner and a fuel supply system, the heating well includes an inner tube and an outer tube, and the inner tube is arranged inside the outer tube; a fuel supply device is arranged in the fuel supply system, and a fuel is conveyed into the burner through a pipeline; and a PLC system, an ignition device, a flameout protection device and a wireless transmission device are arranged in the burner. The apparatus solves the problems in the prior art, such as low efficiency, long repairing cycle, incomplete decontamination and single energy source. The in-situ fuel gas thermal desorption apparatus provided by the invention has the advantages of high efficiency, greenness, environmental protection, short repairing cycle, energy diversity and reusability.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to an in-situ gas thermal desorption device for soil remediation treatment. Background technique [0002] As the basis of industrial and agricultural production and an important part of environmental elements, soil is a natural resource for human survival. It absorbs about 90% of pollutants in the environment. With the advancement of suburbanization and anti-urbanization, a large number of urban enterprises have relocated. In 2008, the number of enterprises shut down and transferred in my country reached 22,488. Phenomena such as leaks and various environmental accidents will cause various volatile pollutants to enter the soil of the site, forming a large number of polluted sites that need to be repaired urgently. Volatile organic pollutants are one of the most prominent and common pollutants in the soil of industrial sites. They have been listed as priority pollutants, whic...
