Efficient thermal desorption equipment for soil organic pollution remediation

Abstract

The invention discloses efficient thermal desorption equipment for soil organic pollution remediation. The efficient thermal desorption equipment comprises a treatment box, wherein a material inlet pipe is inserted into the upper end of the treatment box in a penetrating manner, a material outlet groove is formed in one end, far away from the material inlet pipe, of the treatment box, a connectingpipe is fixed to the inner wall of one end, away from the material inlet pipe, of the treatment box, one end, close to the material inlet pipe, of the connecting pipe is rotationally connected to anauger rotating pipe penetrating through the side wall of the treatment box, a driving motor is welded to the outer wall of one end, away from the material inlet pipe, of the treatment box, and the output shaft of the driving motor penetrates through the side wall of the treatment box, and is welded to the side wall of the auger rotating pipe. According to the invention, by driving the auger rotating pipe to rotate through the driving motor, the auger rotating blade pushes the soil in the rotating process to form the continuous and effective thermal desorption treatment procedure, so that onlythe untreated soil needs to be manually guided into material inlet pipe so as to partially reduce the manual control in the whole treatment process, substantially reduce manual labor and reduce the error rate caused by manual operation.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a high-efficiency thermal desorption device for soil organic pollution remediation. Background technique [0002] With the increasing of soil organic pollution, the remediation of organic polluted solid waste is one of the key means of soil organic pollution recovery; the existing technologies used for remediation of organic polluted solid waste include: biological remediation process, chemical rinsing process, Gas phase extraction technology and thermal desorption method; [0003] Among them, thermal desorption technology is a technology that desorbs volatile substances from non-volatile substances through direct or indirect heating. It is one of the effective technologies for remediating polluted soil; unlike incineration, thermal desorption technology does not make organic pollution Instead, the organic pollution components in the soil are heated to volatilize throug...
