Polluted soil thermal desorption treatment equipment is an environmental protection technology equipment that evaporates/separates organic pollutants (such as volatile organic compounds, semi-volatile organic compounds, petroleum hydrocarbons, polychlorinated biphenyls, etc.) or heavy metals in soil through heating,and conducts subsequent treatment. Direct thermal desorption: Soil comes into direct contact with a heat source, and high temperatures usually 150-550 ℃ cause pollutants to evaporate. Indirect thermal desorption: indirectly heating soil through a heat exchanger to reduce secondary pollution of soil caused by combustion exhaust gas Advantages: Wide processing range (organic matter, some heavy metals). High efficiency removal rate can reach over 99%. Reusable soil can be reused after treatment.
