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

Embodiment

[0029] Such as figure 1 The shown integrated device for remediation of volatile contaminated soil includes an outer shell 1 with a supporting leg 15 at the bottom. The outer shell 1 is provided with a soil storage cavity 4, an ozone oxidation mechanism, and a neutralization spray from bottom to top. The drenching mechanism and the adsorption mechanism 9, one side of the outer shell 1 is provided with a feed port 13 communicating with the soil storage cavity 4, and the ozone oxidation mechanism includes an ozone oxidation water storage tank 12, and an aerator located in the ozone oxidation water storage tank 12 The gas plate 11 and the ozone oxidation water spray pipe 10 directly above the ozone oxidation water storage tank 12, the neutralization spray mechanism includes a liquid collection tank 6 and a neutralization liquid spray tube 7 directly above the liquid collection tank 6, The adsorption mechanism 9 includes activated carbon filled, the upper sides of both sides of the o...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is:

[0040] In this embodiment, as figure 1 As shown, the corresponding side of the outer shell 1 on which the baffle 5 is located is inclinedly arranged above the soil storage cavity 4, and the distance between the corresponding two sides gradually decreases from bottom to top. The corresponding parts of the outer shell 1 are arranged obliquely and gathered upwards, which can promote the gathering of volatile gases to the middle, and the length of the treated area above the gas is small, so that the products and residues (solid and liquid) in the spray treatment process ) Can completely fall into the corresponding tank body when it is dropped, thereby avoiding secondary pollution caused by the products and residues falling into the soil during the aforementioned spray treatment process.

[0041] Others are the same as in Example 1.

Embodiment 3

[0043] The difference between this embodiment and Embodiment 1 is:

[0044] In this embodiment, as Image 6 As shown, the part of the outer casing 1 corresponding to the area where the ozone oxidation mechanism and the neutralization spray mechanism are located is a cylindrical shape with a convex middle part on the side surface. The soil storage cavity 4, the ozone oxidation mechanism, the neutralization spray mechanism and the adsorption mechanism 9 Two partitions are separated by partitions 21. Each partition 21 is provided with a communication port 20 on one side, and the communication ports 20 on every two adjacent partitions 21 are located on two opposite sides, below The communication ports 20 on the two partitions 21 of the two partitions are all inclined toward the corresponding side inner wall of the outer shell 1 above them; the top of the suction mechanism 9 is provided with a blocking plate 22, which faces away from the suction mechanism 9 There is a gap between one...

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...
