A Soil Thermal Desorption Restoration Device Based on Solar Energy

Abstract

The invention relates to the technical field of soil treatment and discloses a thermal desorption remediation device based on solar energy for soil. The thermal desorption remediation device comprises a support and a horizontal heating cylinder arranged on the support, a feed channel is formed in the upper side of the left end of the heating cylinder, a discharge channel is formed in the lower side of the right end of the heating cylinder, a solar thermal collection pipe is arranged on the outer side of the heating cylinder, a solar reflection plate is arranged on one side of the support, a main shaft is arranged inside the heating cylinder, a spiral band is arranged on the surface of the main shaft, a motor driving the main shaft to rotate is arranged on the support, an air inlet pipe is arranged on the upper side of the left end of the heating cylinder, an exhaust pipe is arranged on the upper side of the right end of the heating cylinder, an exhaust fan is arranged on the exhaust pipe, rotating sleeves are fixed to the two ends of the solar thermal collection pipe and are connected to the heating cylinder in a rotating mode, outer teeth are arranged on the outer side of the rotating sleeve at the left end of the solar thermal collection pipe, an auxiliary motor is arranged on the support, and a gear meshed with the outer teeth is arranged at the shaft end of the auxiliary motor. The thermal desorption remediation device has the beneficial effect of greatly lowering the thermal desorption cost of the soil by utilizing the solar energy for heating.

Description

technical field [0001] The invention relates to the technical field of soil remediation treatment, in particular to a solar thermal desorption and remediation device based on solar energy. Background technique [0002] A large amount of soil in my country has been polluted by organic pollutants such as benzene, toluene, xylene, ethylbenzene and TPH. As the public gradually understands the environmental and health hazards of organic pollutants, there is an urgent need for economical and effective methods to deal with these toxic substances. . The main remediation technologies for organic pollutant-contaminated soil include biological remediation, chemical remediation, and physical remediation. In comparison, physical remediation or chemical remediation has wider applicability, especially for high-concentration, multi-component organic pollution sites. Among many physical or chemical remediation technologies, thermal desorption is recognized as a mature and reliable technology...
