Description

technical field [0001] The invention belongs to the field of soil restoration, in particular to thermal analysis equipment, especially direct thermal analysis equipment. Background technique [0002] Thermal desorption technology is an important contaminated soil remediation technology, which can remediate the soil that has been polluted by organic matter, and can achieve a good remediation effect. It uses heating to heat the soil polluted by organic matter to above the boiling point of the organic matter, so that the organic matter adsorbed in the soil is volatilized into a gaseous state and then separated. Thermal desorption technology can effectively remove volatile organic compounds, such as aromatic hydrocarbons, etc., and can also effectively remove low-volatility and refractory organic pollutants such as PCBs, DDT, Dioxins, and chlorine-containing pesticides. Organic pollutants with different boiling points can be heated at one time to achieve the remediation target ...
