For the soil remediation project containing volatile and semi-volatile organic pollutants,a city soil remediation project adopts ex-situ direct thermal desorption technology and equipment.Contaminated soil after preprocessing,then through rotary kiln for hot stripping,organic pollutants and the soil particle separation,removal,the enrichment of gasification of pollutant exhaust by the cyclone dust removal,secondary combustion chamber cooling high temperature decomposition,heat exchanger,half dry acid alkali reaction tower,bag dust removal for tail gas treatment,effectively remove the pollutants in the exhaust gas.The technology is mature and the equipment is stable,which can meet the environmental protection requirements of organic contaminated soil remediation.
