Abstract

The invention relates to the technical field of soil remediation, and discloses contaminated soil remediation equipment capable of achieving electromagnetic heating through magnetic separation, the contaminated soil remediation equipment comprises an equipment main body, a feeding port is formed in the top of the equipment main body, a driving shaft center is arranged in the equipment main body, and a spiral stirring blade is arranged on the outer side of the driving shaft center. According to the contaminated soil remediation equipment achieving electromagnetic heating through magnetic separation, an electromagnetic controller is started to drive an electromagnetic coil to generate high current, the surface of a magnetic heating plate in lap joint with the electromagnetic coil is wound with the high current immediately, and the surface temperature of the magnetic heating plate rises immediately based on the electromagnetic effect; a closed heating cavity is formed in the circumferential trough on the outer side of the iron powder, based on the principle that the iron powder is heated quickly, the contaminated soil mixed with the iron powder is heated immediately and quickly, the contaminated soil is heated above the boiling point of a target pollutant, the pollutant is effectively promoted to be gasified and volatilized, and the target pollutant and soil particles are separated and removed.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a contaminated soil restoration device that realizes electromagnetic heating through magnetic separation. Background technique [0002] With the development of society and the gradual intensification of industrialization, the number of industrially polluted sites has gradually increased, causing serious environmental hazards; in order to ensure the ecological environment and human health, the restoration of polluted soil in polluted sites has become an inevitable trend. [0003] As an important adsorption technology for contaminated soil, thermal desorption technology is suitable for contaminated soil due to its short treatment period and good effect. At present, it has been widely used in engineering practice abroad. From 1982 to 2004, about 70 US Superfund projects adopted this technology. It can deal with a wide range of volatile organic compounds, semi-volatile organ...
