Example Embodiment

[0023] Example 1

[0024] Reference figure 1 , An ex-situ repair device for repairing soil with high temperature gas heating, comprising a box body 1 and a feeding nozzle 5 arranged at the upper end of the box body 1 and a discharge nozzle 6 arranged at the lower end of the box body 1. A horizontal edge is arranged in the box body 1. The heat insulation board is arranged in the same direction. The heat insulation board divides the box body 1 into a heating cavity located in the upper half and a cooling cavity located in the lower half. The heat insulation board is embedded with an air duct 10 arranged in a horizontal direction. One end of 10 penetrates the inner wall of the box 1 and is installed with an air compressor 8. A vortex tube 2 is installed on the heat shield, and the input end of the vortex tube 2 is connected with the output end of the air duct 10, and the hot gas output end of the vortex tube 2 The cold air output end of the vortex tube 2 penetrates the heat insulati...

[0026] Example 2

[0027] Reference Figure 2-3 , The rotating shaft 3 located in the cooling cavity is provided with a water delivery cavity 20 along its radial direction. The surface of the rotating shaft 3 is evenly distributed with drainage micropores 21 communicating with the water delivery cavity 20, and the lower end of the box body 1 is fixedly connected with a liquid storage tank 11 , The side wall of the liquid storage tank 11 is installed with a liquid pumping device for pumping the bacterial liquid in the liquid storage tank 11 into the water delivery cavity 20.

[0028] The pumping device includes a sliding plug barrel 12 fixedly connected to the side wall of the liquid storage tank 11. The lower end of the sliding plug barrel 12 is connected to the liquid storage tank 11, and the connection is installed to allow only bacterial liquid to enter from the liquid storage tank 11. The first one-way valve in the sliding plug cylinder 12 is sealed and slidingly connected to ...

Abstract

The invention discloses an ectopic remediation device for high-temperature gas heating remediation of soil, the ectopic remediation device comprises a box body, a feeding nozzle arranged at the upperend of the box body and a discharging nozzle arranged at the lower end of the box body, wherein a heat insulation plate arranged along the horizontal direction is arranged in the box body, the heat insulation plate divides the box body into a heating cavity arranged at the upper half part and a cooling cavity arranged at the lower half part, an air duct arranged along the horizontal direction is embedded in the heat insulation plate, and one end of the air duct penetrates through the inner wall of the box body and is provided with an air compressor. According to the invention, a pressurized gas is shunted through a vortex tube, so that high-temperature remediation and cooling of the soil are simultaneously completed in one device, and the flow is simplified; an impeller is driven to rotateby airflow, a rotating shaft drives auger blades to rotate, and the auger blades push the soil to form a continuous thermal desorption process, so that only the soil needs to be continuously added, no additional driving force needs to be provided, energy is saved, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an ex-situ remediation device for remediating soil by heating with high-temperature gas. Background technique [0002] Thermal desorption technology is a technology that desorbs volatile substances from non-volatile substances by direct or indirect heating. It is one of the effective technologies for remediating polluted soil; unlike incineration, thermal desorption technology does not make organic pollutants Instead, the organic pollution components in the soil are heated to volatilize through direct or indirect heating, so that the organic pollution components are separated from the soil, and the purpose of remediating the soil is achieved; [0003] The existing thermal desorption equipment is huge and costly. After heating the soil, it needs to cool down the soil. After the cooling is completed, it is necessary to spray microbial liquid to repair the thermally desorbe...
