Abstract

The invention provides an environment-friendly organic polluted soil thermal desorption remediation system. The system comprises an integrated feeding and crushing mechanism, a thermal desorption mechanism, a flue gas dust removal mechanism and a charcoal preparation mechanism, wherein the integrated feeding and crushing mechanism is used for crushing and drying organic polluted soil; the thermaldesorption mechanism is used for carrying out thermal desorption treatment on the crushed and dried organic polluted soil; the flue gas dust removal mechanism is used for carrying out harmless treatment on harmful gas and flue gas tail gas generated by crushing and drying and thermal desorption treatment of the organic polluted soil; the charcoal preparation mechanism is used for preparing charcoal by utilizing high-temperature waste heat generated after the soil is subjected to the thermal desorption treatment; and the four mechanisms cooperatively work to remediate and treat the organic polluted soil. The system is simple in structure, the organic polluted soil is treated, no toxic gas is generated, the charcoal can be prepared by the waste heat generated by heat desorption of the soil,so that the system is very environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to the technical field of organic polluted soil treatment, in particular to an environment-friendly thermal desorption restoration system for organic polluted soil. Background technique [0002] With the development of my country's economy, more and more organic chemicals are released into the natural environment, most of which enter the soil environment, and the soil ecosystem has become the largest receptor for organic pollutants, and even some organic pollutants are toxic and Bioaccumulation, which can persist in the soil environment, is increasingly harmful to the ecological environment and human health. [0003] There are many sources of organic pollutants. The bubbling, dripping, and discharge of three wastes in the production process of organic chemical production enterprises will cause high concentrations of organic pollutants to remain in the soil around the production workshop or warehouse; during the circulation and use ...
