AI Technical Summary
The soil temperature after thermal desorption and remediation is relatively high, and the cooling rate is slow, which leads to a longer development and utilization cycle of the land.
The system employs an insulated cover plate and sedimentation tank structure. It uses a heating well to inject clean water and a pumping well to extract the mud-water mixture for sedimentation. Combined with a heat exchange mechanism, it achieves simultaneous cooling and sedimentation, and recovers heat energy for use in refrigeration equipment, thus realizing efficient energy utilization.
It achieves rapid cooling after soil remediation, saves water used for cooling, improves the efficiency of land development and utilization, and realizes efficient recovery and utilization of heat energy.
