According to the energy supply form, the high-temperature heating pipe can adopt both gas and electric heating; according to the vertical distribution of the pollutant in the formation, the length of the high-temperature heating pipe is reasonably determined, and the target pollutant is targeted and heated;

Relying on the on-site hydrogeological conditions, the temperature field simulation calculation is carried out, and the gas dynamics calculation is extracted to obtain the optimal design layout of the heating pipe and the extraction pipe;

Innovatively configured flue gas waste heat utilization system to realize secondary heating of the soil through flue gas recovery, which greatly saves energy consumption and improves thermal efficiency by more than 50%;

There is no need to excavate, even after excavation, it could also realize in-situ remediation, the depth can reach 20 meters. There is no secondary pollution such as odor, noise during excavation or transportation, or mass incidents risk.
