A method of using a soil pesticide thermal desorption device

Abstract

The invention relates to the technical field of soil treatment, and discloses a method for using a soil pesticide thermal desorption device, which includes a frame and a cabinet arranged on the frame. A heating cavity is arranged in the cabinet, a combustion chamber is provided at the bottom of the cabinet, and a combustion chamber is arranged in the cabinet. There are upper and lower feeding cylinders distributed horizontally, and a feeding hopper is provided on the top of the cabinet. The lower end of the feeding hopper communicates with the left end of the upper feeding cylinder through the feeding channel, and the right end of the upper feeding tube passes through the connecting channel. It communicates with the right end of the lower feeding barrel, the left end of the lower feeding barrel is provided with a discharge channel, the upper feeding barrel is provided with an upper shaft, the upper shaft is provided with an upper spiral belt, and the lower feeding barrel is provided with a lower shaft. The lower rotating shaft is provided with a lower spiral belt, and the ends of the upper rotating shaft and the lower rotating shaft are connected by a synchronous belt. The top of the frame is provided with a motor for driving the upper rotating shaft to rotate. The invention has the beneficial effects of crushing, stirring and heating the soil, greatly eliminating residual pesticides in the soil, and high soil repair efficiency.

Description

technical field [0001] The invention relates to the technical field of soil remediation treatment, in particular to a method for using a soil pesticide 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 soil contaminated by organic pollutants include biological remediation, chemical remediation, physical remediation, etc. In comparison, physical remediation or chemical remediation has wider applicability, especially for high-concentration, multi-component organic pollution contaminated sites . Some orchards and gardens are often sprayed with pesticides and insecticides, and the residual pesticides and insect...
