This invention belongs to the field of in-situ remediation technology for contaminated sites, specifically relating to a gas-phase extraction system and remediation method for contaminated sites based on freeze-thaw and heating cycles. It includes several air compressors, the outlets of which are connected to the air inlets of a vortex tube control box via pipelines. The hot and cold air outlets of the vortex tube control box are connected to the central inlet and loop inlet of a well pipe via hot and cold air pipelines, respectively. The loop inlet of the well pipe is also connected to the outlet of an atomizing device via an atomizing pipeline. The atomizing pipeline, cold air pipeline, and loop inlet are interconnected via a three-way valve. This invention tightly couples the "physical pore-expanding" effect of soil freeze-thaw with the "thermal desorption" effect of heating in space and time. First, soil mass transfer conditions are improved through freeze-thaw and heating, while simultaneously, pollutant desorption is enhanced through heating. The synergistic effect of these two methods overcomes the mass transfer bottleneck in the remediation of low-permeability soils, significantly improving the overall efficiency of gas-phase extraction.
