Soil remediation device for contaminated soil regeneration

Abstract

The invention relates to the technical field of contaminated soil regeneration, and discloses a soil remediation device for contaminated soil regeneration, the soil remediation device comprises a shell, the bottom of the shell is movably connected with a drill bit; and the device automatically penetrates into the deep layer of soil in a rotating mode, damage to the surface soil is small, meanwhile, the deep layer soil is convenient to repair, soil regeneration is facilitated, by means of the capacitance principle, agent spraying operation is triggered, linkage between the structures is improved, and operation is more convenient and faster. Under the combined action of the drill bit, a water disc, a pressing plate, a moving block, a second gear, a sector plate and a rotating plate, rotary spraying is carried out on deep soil while an agent is automatically sprayed to surface soil, the contact area of the deep soil and the agent is increased, the surface soil and the deep soil can be comprehensively absorbed, the situation that the working efficiency is too low due to a single remediation layer is avoided, the repairing efficiency is effectively improved, and the higher automation degree is achieved.

Description

technical field [0001] The invention relates to the technical field of contaminated soil regeneration, in particular to a soil restoration device for regeneration of contaminated soil. Background technique [0002] Soil remediation is one of the commonly used methods in the field of soil pollution regeneration, and it is a technical measure to restore the normal function of polluted soil by means of physical, chemical and biological technology. In-situ remediation is one of the common soil remediation methods. In situ remediation is the direct remediation or treatment of soil in contaminated sites. Usually, the remediation agent is sprayed on the soil surface. Although the soil has the function of self-purification, it can transform the harmful substances in the soil to a harmless level, and restore the soil to the state before pollution, but the deep soil will still be violated, so that the soil is repaired. Incomplete repair occurs during the process, which reduces the r...

Problems solved by technology

Usually, the remediation agent is sprayed on the soil surface. Although the soil has the function of self-purification, it can transform the harmful substances in the soil to a harmless level, and restore the soil to the state before pollution, but the deep soil will still be violated, so that the soil is repaired. Incomplete repair occurs during the process, which reduces the repair quality. However, when the existing deep repair device is used, the repair layer is single, and the surface layer cannot be operated, which seriously reduces the repair work efficiency.

[0003] Aiming at the deficiencies of the prior art, the present invention provides a soil remediation device for regeneration of contaminated soil, which has the advantages of synchronous remediation of multi-layer soil and convenient operation, and solves the problems of single remediation level and low work efficiency. The method automatically penetrates deep into the soil, which is less damaging to the surface soil and at the same time facilitates the repair of the deep soil, which is conducive to the regeneration of the soil, and uses the principle of capacitance to trigger the chemical spraying operation, automatically spraying the chemical agent on the surface soil and the deep soil at the same time. Rotary spraying increases the contact area between the deep soil and the agent, so that the surface and deep soil can be fully absorbed, avoiding the situation of low work efficiency due to a single repair layer, effectively improving the repair efficiency, and having a higher degree of automation
