Volatile contaminated soil remediation integrated device

Abstract

The invention discloses a volatile contaminated soil remediation integrated device, and belongs to the technical field of contaminated soil treatment. The device comprises an outer shell of which thetop is provided with an exhaust fan, and a soil storage cavity, a ozone oxidation mechanism, a neutralization spraying mechanism and an adsorption mechanism which are arranged in the outer shell. A rotating cylinder and arc-shaped plates arranged along the circumference of the inner side of the rotating cylinder at equal intervals are arranged in the soil storage cavity, and stirring plates are fixed to the outer side face of the rotating cylinder along the circumference of the rotating cylinder at equal intervals; a through hole is formed in the rotating cylinder between every two adjacent stirring plates, the arc-shaped plates are in one-to-one correspondence with the through holes and block the inner sides of the through holes, one side of each arc-shaped plate is hinged to the inner side face of the rotating cylinder, torsional springs are arranged at the hinged positions, and through holes allowing soil to pass through but not allowing stones to pass through are formed in the arc-shaped plates in a full-distributed mode. The soil remediation integrated device can disperse soil, volatile matter in the soil can be fully volatilized conveniently, and remediation is more thorough;meanwhile, stones in the soil can be separated out, and the quality of the treated soil can be improved.

Description

Technical field [0001] The invention relates to the technical field of contaminated soil treatment, in particular to an integrated device for remediation of volatile contaminated soil. Background technique [0002] Soil is at the center of the inorganic and biological realms in the terrestrial ecosystem. It not only circulates energy and material in this system, but also continuously exchanges materials with waters, atmosphere and organisms. Once pollution occurs, one of the three There will be mutual transfer of pollutants. [0003] The current integrated device for remediation of volatile contaminated soil uses air intake and exhaust to volatilize the soil when remediating the soil. Since the soil may contain water and the soil is too densely packed, when volatilizing, The soil on the surface is easy to volatilize, while the buried in the middle of the soil is not easy to volatilize, making the soil restoration incomplete; and the inevitable rocks in the soil cannot be separated...

Problems solved by technology

[0003] The current volatile polluted soil remediation integrated device uses air intake and exhaust to volatilize the soil when remediating the soil. Since the soil may contain moisture in the soil, and the soil piles are too dense, when volatilizing, The soil on the surface is easy to volatilize, but the soil buried in the middle of the soil is not easy to volatilize, which makes the soil restoration incomplete; and the stones that inevitably exist in the soil cannot be separated from the soil, which is not conducive to improving the quality of the treated soil
