Problems solved by technology
[0005] Thermal desorption consumes a lot of energy in the process of treating polluted soil, and produces a large amount of high-temperature wastewater. If it is directly treated and discharged, it will not only cause a large amount of energy loss, but also generate a certain amount of wastewater treatment costs.
Normal temperature desorption technology is greatly affected by temperature and region. In summer or in the south, the temperature is higher and the pollutant removal efficiency is better. In autumn and winter or in the north, this technology cannot achieve the ideal repair effect due to weather conditions.

Abstract
The invention relates to a waste heat utilization system using thermal desorption high temperature cycle spray wastewater to improve normal temperature desorption booth processing efficiency. The system comprises a thermal desorption spraying system, a wastewater adjusting system, a wastewater processing system, and a booth ground heating system. The thermal desorption spraying system is connected to the wastewater adjusting system. The wastewater adjusting system is connected to the wastewater processing system. The wastewater processing system is connected to the booth ground heating system. The booth ground heating system is connected to the thermal desorption spraying system and / or the wastewater adjusting system. The high temperature spraying cycle wastewater generated by thermal desorption is utilized to heat the polluted soil in a normal temperature desorption booth, the energy is fully utilized, and at the same time the processing effect of the normal temperature desorption technology is improved by the waste heat utilization system. The thermal desorption technology and normal temperature desorption technology are co-used in the system, and the novel system is economic, reliable, and stable, and is especially suitable for repairing and processing soil polluted by volatile / semi-volatile organic matters.
Description
technical field [0001] The invention relates to the field of contaminated soil treatment, in particular to a waste heat utilization system that uses thermal desorption high-temperature circulating spray wastewater to improve the treatment efficiency of normal-temperature desorption greenhouses. It is used to increase the soil temperature of the room temperature desorption greenhouse, and improves the treatment efficiency of the room temperature desorption while realizing the comprehensive utilization of energy. Background technique [0002] With the development of industrialization and urbanization in our country, a large number of chemical companies have relocated or are about to be decommissioned in recent years. These companies have caused site pollution problems due to waste dumping and discharge, product production and treatment, and chemical substance leakage. , This type of soil pollution is mainly volatile or semi-volatile organic compounds. At present, most of the ...
