| titleOfInvention | Method and apparatus for extracting volatile soil pollutants |
| abstract | (57) [Summary] [PROBLEMS] When repairing contaminated soil by gas-liquid mixed extraction method, while eliminating the danger of explosion disaster due to the vaporization of volatile soil contaminants, ensuring the safety of contaminated soil restoration work, Reduce the cost of soil restoration. SOLUTION: Cold air is blown from a cold air discharge port 6a of a vortex cooling device 6 into a suction pipe 1a near the ground surface of a suction well 1, and mixed with a gas-liquid mixed fluid of soil gas and groundwater sucked from contaminated soil. To prevent volatile soil pollutants from evaporating. To prevent freezing around the cool air discharge port 6a, warm air is blown from the warm air discharge port 6b of the vortex cooling device 6 to the outer surface of the suction pipe 1a. |
