Dish type solar heat collecting single pile for thermal desorption treatment of soil organic pollutants

Abstract

The invention belongs to the technical field of geotechnical engineering and particularly relates to a dish type solar heat collecting single pile for thermal desorption treatment of soil organic pollutants. The device is composed of a thermal desorption pile body, an escape pile body, a vehicle track racing with the sun, a vehicle racing with the sun, a controller, a dish type mirror and other components. Each thermal desorption pile device is equipped with two escape piles which can be arranged in a hexagonal plum-blossom-shaped combination manner. The local sun track parameters are input into the controller in advance, the controller controls the vehicle racing with the sun to move along the circular-arc-shaped track racing with the sun, and meanwhile a telescopic rod is controlled so that the dish type mirror can be always facing the sun. The heat collecting plate reflects sunlight onto a heat collector, and the heat collector transfers heat to the thermal desorption pile body after being heated, so that the soil is heated, and low-boiling-point organic matter in the soil is heated to escape through the escape piles. The device can utilize solar energy to treat the organic pollutions in the polluted soil by the thermal desorption method, can be arranged in combination and serve together and is a novel polluted soil treatment device.

Description

technical field [0001] The invention belongs to the technical fields of geotechnical engineering and environmental engineering, and in particular relates to a dish-type solar heat-collecting single pile for thermal desorption treatment of soil organic pollutants. Background technique [0002] With the acceleration of industrialization and urbanization in our country, the soil in many areas of our country is threatened by more and more pollution. Among them, the problem of organic matter polluted soil has attracted more and more attention because of its harmfulness and high observability. Thermal desorption is widely used as an effective method to treat organic pollutants in soil. The principle of thermal desorption to treat organic pollutants is to heat the organic pollutant components in the soil to a high enough temperature through direct or indirect heat exchange to evaporate and separate from the soil medium. [0003] At present, the technology of thermal desorption to ...

Problems solved by technology

If solar energy can be used for thermal desorption to remediate soil, a relatively environmentally friendly and low-energy consumption method can be adopted to improve the energy economy of contaminated soil remediation. At present, there is no comprehensive supporting technology for using solar thermal desorption to treat organic pollution in polluted soil. How to effectively apply solar energy to thermal desorption treatment is an urgent problem to be solved
