Abstract

The invention relates to an organic polluted pile building thermal desorption system, which comprises a heat preservation isolation layer used for wrapping a polluted soil pile body, a heating pipeline buried in the polluted soil pile body and used for uniformly heating the polluted soil pile body, and an extraction pipeline used for sucking organic steam in the polluted soil pile body. The invention also relates to an organic polluted pile building thermal desorption system method. The method has the beneficial effects that on the premise that the treatment effect of the organic contaminated soil is guaranteed, a novel low-pollution treatment method is provided, and the treatment benefit is improved.

Description

technical field [0001] The invention belongs to the field of remediation of organic polluted soil, and in particular relates to a thermal desorption technology for pile building. Background technique [0002] In recent years, the thermal desorption technology of contaminated soil has been widely used in the remediation of organic polluted soil. Most of them are in-situ thermal desorption, which is easy to affect the local environment and has low efficiency. Although the effect of ex-situ thermal desorption in the prior art is better, the construction and operation costs are very high, and the operation is extremely complicated. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies of the prior art and solve the problem of high cost of repairing polluted soil by ex-situ thermal desorption. [0004] In order to achieve the purpose of the above invention, a thermal desorption system for building a pile of organic pollution is provide...
