Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, in particular to a heating treatment device for soil remediation. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. Common technologies can be divided into physical, chemical and biological methods. Physical, chemical and biological methods are used to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. With the rapid development of society, many countries in the world, especially developed countries, have formulated and implemented contaminated soil treatment and remediation plans, thus forming an emerging soil remediation industry. In soil remediation, the soil to be remediated needs to be heated by a heating treatment device.

In the heating treatment device for soil remediation, the motor drives the stirring arm to rotate in the box body through the round rod, and then can drive the repair agent to be stirred evenly in the box body. At the same time, the electric heating plate on the inner wall of the box body and the side of the sealing plate can heat the repair agent. While the stirring arm stirs the repair agent, the contact area between the repair agent and the electric heating plate is increased, which effectively solves the problem of poor activity of the effective ingredients of the transmission repair agent when it is in a cooling state, and improves the repair effect on the soil.
