Description

Technical Field

[0001] The invention relates to soil remediation equipment, in particular to soil leaching and remediation equipment. Background Art

[0002] Soil leaching technology refers to the technology of injecting chemical solvents that can promote the dissolution or migration of soil pollutants into contaminated soil, thereby dissolving, separating and treating the pollutants from the soil.

[0003] In the prior art, soil leaching can be divided into in-situ leaching and ex-situ leaching. Generally, ex-situ leaching is suitable for leaching and remediation of smaller volumes of soil. Ex-situ soil leaching often uses a belt conveyor to transport soil, and a spraying device suitable for spraying leaching liquid is provided above the conveyor belt to spray the leaching liquid on the soil when the soil passes through the spraying device to achieve soil leaching. However, it is difficult to ensure uniform arrangement of the soil on the conveyor belt, and the contact time between the soil and the leaching liquid is short, so it is difficult to obtain a good leaching effect.

[0004] Moreover, some contaminated soil will clump after or before contact with the eluent, which will result in the subsequent eluent being unable to fully contact the soil, resulting in the contaminated soil being unable to be fully purified.

[0005] In view of this, the present invention designs a soil leaching and remediation device. Summary of the invention
