Technical Field

[0001] The utility model relates to the technical field of thermal desorption repair devices, in particular to a fuel gas thermal desorption repair device. Background Art

[0002] The gas thermal desorption remediation device is a technology used to treat organic pollutants present in the soil. The device injects gas into the soil to increase the soil temperature and evaporate the organic pollutants from the soil. The evaporated pollutants are then captured and treated to ensure that they no longer pollute the environment. The working principle of this remediation device is based on the principles of combustion and thermal decomposition. After the gas is injected into the soil, the soil temperature is raised by heating. The increase in temperature causes the organic pollutants in the soil to change from a solid phase to a gas phase. These gaseous pollutants are then collected and further treated to ensure that they are completely decomposed or converted into harmless substances. The soil gas thermal desorption remediation device has There are many advantages. First, since it evaporates organic pollutants from the soil, it can quickly and effectively reduce the pollutant content in the soil.
