Mirror array solar heat collection metal monopile device for treating organic polluted soil

Abstract

The invention belongs to the technical field of geotechnical engineering, and in particular relates to a trough type reflecting mirror array solar collector metal single-pile device for thermal desorption treatment of organic matter contaminated soil. The device consists of a thermal desorption pile body, a sun following track, a sun following vehicle base, a motor box, a heat collecting rod, a front reflecting mirror, a lateral reflecting mirror, a change wheel, a driving wheel, a transmission wheel in the change wheel, a transmission wheel of the driving wheel, and the like. The working modeof an electric box is entered in advance, and a transmission belt is used for driving a vehicle body to move along the arc-shaped sun following track, so that a heat collecting system is driven to rotate around the thermal desorption pile body, a trough type reflecting mirror array always faces the sun along the vertical direction, and the mirror array further reflects the sunlight onto the heatcollecting rod. After being heated, the heat collecting rod transfers the heat to the thermal desorption pile body so as to heat the soil. The low-boiling organic matters in the soil escape after being heated, so that the purpose of treating the organic matter contaminated soil is achieved.

Description

technical field [0001] The invention belongs to the technical fields of geotechnical engineering and environmental engineering, and in particular relates to a trough-type reflecting mirror array solar heat-collecting metal monopile device for thermal desorption treatment of organic-contaminated soil. Background technique [0002] With the continuous acceleration of industrialization and urbanization in our country, most of the soil in our country is threatened by more and more pollution. Among them, the problem of soil pollution by organic matter has received more and more attention because of its great harm and high observability. Thermal desorption has been increasingly used as an effective treatment for organic matter-contaminated soils. The principle is to heat the organic pollutant components in the soil to a high enough temperature to evaporate and separate from the soil medium through direct or indirect heat exchange. At present, the main limitation of the applicati...
