Abstract

The invention relates to a device for repairing organic polluted soil through indirect thermal desorption of high-efficiency energy level staged utilization. The device comprises a polluted soil preheating and feeding system (3), an indirect thermal desorption system (4), a hot air and incinerator (5) and a soil discharge cooling system (6); the afterheat of each gas phase link in the indirect thermal desorption process is integrated, so that the energy of the whole system is utilized efficiently in a staged mode. Meanwhile, the content of organic pollutants in tail gas is greatly reduced through high-temperature incineration of the tail gas, so that the disposal difficulty of a subsequent link is reduced; and then the defects that a traditional technology is tedious in a treatment link, multiple in equipment, prone to faults, difficult in treatment of wastewater and bottom mud and the like are overcome.

Description

technical field [0001] The invention belongs to the technical field of soil remediation of polluted sites, and is suitable for containing organic compounds (volatile / semi-volatile / persistent organic compounds) produced in polluted sites such as chemical plants, pesticide plants, smelters, gas stations, chemical storage tanks, and solid waste disposal. / pesticide) contaminated soil remediation, more related to a high-energy level gradient utilization of indirect thermal desorption device for the remediation of organic contaminated soil. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants. When the amount of waste discharged into the soil exceeds the self-purification capacity of the soil, it destroys the original balance of the soil system and causes changes in the composition, structure and function of the soil system. Soil pollution. Due to insufficient early environmental protection measure...
