Abstract

The invention discloses ex-situ thermal desorption equipment for repairing organic contaminated soil, the ex-situ thermal desorption equipment comprises a box body, a heating box, a first motor and a treatment box, the heating box is mounted on the inner top wall of the box body, a detector is mounted on the inner wall of the heating box, the treatment box is mounted on the inner wall of the box body, and an air inlet pipe is mounted at the bottom of the treatment box in a penetrating manner; and one end of the air inlet pipe extends into the heating box, a second motor is installed on the inner bottom wall of the box body, and an electric telescopic rod is installed on the inner wall of the heating box. According to the device, the material turning device is installed, so that material turning can be conducted, heating is uniform, a first motor rotates to drive a first bevel gear to rotate, a second bevel gear rotates to drive a fixing shaft to rotate, the fixing shaft rotates to drive a fixing ring to rotate, and the fixing ring rotates to drive a supporting rod and a material turning groove to rotate; and the soil enters the material turning groove, the soil in the material turning groove falls into the heating box, and the material turning function is achieved.

Description

technical field [0001] The invention relates to the technical field of thermal desorption equipment, in particular to an ectopic thermal desorption equipment used for repairing organic polluted soil. Background technique [0002] Thermal desorption, as a non-combustion technology, has a wide range of pollutant treatment, movable equipment, and reusable soil after remediation. Especially for chlorine-containing organic compounds, non-oxidative combustion can avoid the formation of dioxins and is widely used. Remediation of soil contaminated with organic pollutants. At present, the traditional thermal desorption technology for contaminated soil is drum thermal desorption, and emerging thermal desorption technologies include fluidized bed thermal desorption, microwave thermal desorption technology and far-infrared thermal desorption. Most of the existing thermal desorption equipment The material is heated by means of indirect or indirect heating to volatilize the gas inside, a...
