Soil thermal desorption treatment system with discharge dust removal function

Abstract

The invention discloses a soil thermal desorption treatment system with a discharge dust removal function, and relates to a technology for treating and dedusting soil polluted by organic pollutants. The soil thermal desorption treatment system comprises a thermal desorption treatment system for treating the soil by heating to remove the soil pollutants, a tail gas dust removal system for treating dust generated in a thermal desorption treatment process, a soil retreatment system for subsequently treating the soil subjected to thermal desorption treatment, and a soil dust removal system, wherein the input of the soil retreatment system is connected with the output of the thermal desorption treatment system, and the input of the soil dust removal system is connected with the output of the soil retreatment system. According to the soil thermal desorption treatment system, raised dust of the discharged soil is effectively controlled through the soil retreatment system and the soil dust removal system; during field operation, basically no raised dust is generated at the discharge hole of thermal desorption equipment, so that the field production environment is greatly improved; also, the resource recycling can be achieved.

Description

technical field [0001] The invention relates to an organic pollutant-contaminated soil treatment and dust removal technology, in particular to a soil thermal desorption treatment system with the function of discharging dust and removing dust. Background technique [0002] In the past few decades, due to a series of factors such as the production and use of pesticides and other chemicals, the discharge and dumping of waste residues and liquids, and the leakage of production processes, a large amount of organic pollutants have been discharged into the environment, and finally accumulated in the soil environment, resulting in Serious soil organic pollution has caused disadvantages and threats to the safe use of soil and agricultural production in my country, and urgently needs to be repaired. [0003] Thermal desorption technology is one of the most commonly used and mature organic contaminated soil remediation technologies. Its main principle is to use direct or indirect heat e...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a soil thermal desorption treatment system with the function of discharging and dust removal, which solves the problem that the soil at the discharge port of the thermal desorption equipment in the prior art is relatively dry, and the soil still contains a large amount of dust particles, which is easy to generate a large amount of dust , the problem of poor on-site operating environment
