Abstract

The invention relates to the technical field of soil treatment and discloses an energy-saving soil contamination thermal desorption device. The device comprises a support and a horizontal heating barrel arranged on the support, wherein a feeding channel is formed in the upper side of the left end of the heating barrel, a discharging channel is formed in the lower side of the right end of the heating barrel, a solar heat collecting tube is arranged on the outer side of the heating barrel, a solar reflector is arranged on one side of the support, a spindle is arranged in the heating barrel, a screw belt is arranged on the surface of the spindle, a motor for driving the spindle to rotate is arranged on the support, an air inlet pipe is arranged on the upper side of the left end of the heating barrel, an exhaust pipe is arranged on the upper side of the right end of the heating barrel, and an exhaust fan is arranged on the exhaust pipe. The device is heated by solar energy, energy is saved, and the soil thermal desorption cost is reduced.

Description

technical field [0001] The invention relates to the technical field of soil remediation treatment, in particular to a soil pollution thermal desorption device. 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 for treating organic matter-co...
