Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to an isolation device for steam extraction remediation of organically contaminated soil. Background Technology

[0002] Organically polluted soil refers to soil whose quality and function have been impaired due to the intrusion or accumulation of organic pollutants. This type of pollution can have a significant impact on the ecological environment, human health, and the function of soil ecosystems. Remediation technologies for organically polluted soil typically include physical remediation, chemical remediation, and bioremediation. Steam extraction remediation is a type of physical remediation technology.

[0003] Steam extraction remediation of organic contaminated soil is an in-situ or ex-situ remediation technology for volatile organic pollutants and some semi-volatile organic pollutants. Its core principle is to inject hot steam or air into the contaminated soil through injection wells, causing the pollutants to volatilize and migrate with the airflow. The contaminated air is then extracted through extraction wells, thereby achieving the purpose of removing the pollutants.

[0004] However, considering that in the existing soil steam extraction remediation process, when steam flows in the soil, it carries away pollutants from the soil and causes them to escape. This means that pollutants in the soil to be remediated can easily flow with the steam to uncontaminated or remediated soil areas, resulting in secondary pollution of the uncontaminated and remediated soil areas and reducing the remediation effect of soil steam extraction remediation. Utility Model Content

[0005] The purpose of this invention is to provide an isolation device for steam extraction remediation of organically contaminated soil.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An isolation device for steam extraction remediation of organic contaminated soil is provided, comprising multiple inserts, multiple enclosure mechanisms, a positioning mechanism, and an air injection cylinder. The multiple enclosure mechanisms can be installed and detached from the multiple inserts through multiple connecting mechanisms. The enclosure mechanisms are used to block air in the soil. The air injection cylinder is inserted and installed on the inserts, and the air injection cylinder has an air outlet. The positioning mechanism is used to position the air injection cylinder.

[0008] Each connecting mechanism includes a first connecting rod and a second connecting rod. The first connecting rod is rotatably mounted on the insert via a ring, and the second connecting rod is rotatably mounted on the insert via a cylindrical tube.

[0009] Furthermore, each enclosure mechanism includes a partition plate, a telescopic plate, and two T-blocks. The telescopic plate is slidably installed on the partition plate, and the two T-blocks are fixedly installed on the partition plate and the telescopic plate, respectively.

[0010] Furthermore, each enclosure mechanism also includes a wedge block, which is connected to the telescopic plate by a spring and is slidably connected to the telescopic plate. The isolation plate has a slot, and the wedge block engages with the slot.

[0011] Furthermore, the positioning mechanism includes a cylindrical block, a semi-circular ring, a cross rod, and a stop. The cylindrical block is fixedly installed on the air injection cylinder, the cross rod is fixedly installed on the insert cylinder, and the cross rod passes through the semi-circular ring. The stop is fixedly installed on the cross rod, and the stop and the semi-circular ring are connected by a return spring.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent.

[0025] Reference Figures 1 to 3 An isolation device for steam extraction remediation of organically contaminated soil is shown, comprising multiple inserts 1, multiple enclosure mechanisms 3, a positioning mechanism 4, and an injection cylinder 5. The multiple enclosure mechanisms 3 can be installed and disassembled onto the multiple inserts 1 via multiple connecting mechanisms 2. The multiple inserts 1 and the multiple enclosure mechanisms 3 are connected end to end, thereby forming a certain spatial area to block steam pollutants. The enclosure mechanisms 3 are used to block air in the soil, thereby preventing pollutants in the soil to be remediated area from escaping to other areas with the steam. The injection cylinder 5 is inserted and installed on the inserts 1, and the injection cylinder 5 has an air outlet 51. The injection cylinder 5 injects steam into the soil to be remediated area through the air outlet 51. The positioning mechanism 4 is used to position the injection cylinder 5, thereby preventing the injection cylinder 5 from deflecting inside the inserts 1. Each connecting mechanism 2 includes a first connecting rod 21 and a second connecting rod 23. The first connecting rod 21 is rotatably mounted on the insert 1 via a ring 22. The rotation of the first connecting rod 21 can adjust its angle. The second connecting rod 23 is rotatably mounted on the insert 1 via a cylindrical tube 24. The rotation of the second connecting rod 23 can adjust its angle, thereby adjusting the installation angle of the isolation plate 31 and the telescopic plate 33 to suit soil remediation areas of different shapes.

[0026] Reference Figure 4 and Figure 5 Each enclosure mechanism 3 includes an isolation plate 31, a telescopic plate 33, and two T-shaped blocks 34. The telescopic plate 33 is slidably installed on the isolation plate 31. Through the sliding effect of the telescopic plate 33, the actual size of the telescopic plate 33 can be adjusted, which facilitates the installation of the isolation plate 31 and the telescopic plate 33 between two inserts 1 with different spacings. The two T-shaped blocks 34 are respectively fixedly installed on the isolation plate 31 and the telescopic plate 33. The bottom of the isolation plate 31 and the telescopic plate 33 are provided with a beveled surface, which facilitates the insertion of the isolation plate 31 and the telescopic plate 33 into the soil. Each enclosure mechanism 3 also includes a wedge 36, which is connected to the telescopic plate 33 by a spring 35. The wedge 36 and the telescopic plate 33 are slidably connected. Through the elastic force of the spring 35, the wedge 36 is always engaged with the slot 37 when no external force is applied. The isolation plate 31 has a slot 37, and the wedge 36 engages with the slot 37. Through the engagement effect of the wedge 36 and the slot 37, the telescopic plate 33 can be limited to prevent it from moving, thus facilitating the storage of the isolation plate 31 and the telescopic plate 33.

[0027] Reference Figure 3 and Figure 6 The positioning mechanism 4 includes a cylindrical block 41, a semi-circular ring 42, a crossbar 43, and a stop block 44. The cylindrical block 41 is fixedly installed on the air injection cylinder 5, and four cylindrical blocks 41 are arranged circumferentially around the air injection cylinder 5. The crossbar 43 is fixedly installed on the insert cylinder 1 and passes through the semi-circular ring 42. Two semi-circular rings 42 are symmetrically distributed. The crossbar 43 guides the semi-circular rings 42 to prevent them from shifting during movement. The stop block 44 is fixedly installed on the crossbar 43, and the stop block... The semicircular ring 44 and the semicircular ring 42 are connected by a return spring 45. The return spring 45 ensures that the semicircular ring 42 always stays close to the middle of the insert 1 when no external force is applied, so that the mounting groove 49 engages with the cylindrical block 41. Both the semicircular ring 42 and the insert 1 are provided with mounting grooves 49 that match the cylindrical block 41. By engaging the cylindrical block 41 with the mounting groove 49, the air cylinder 5 can be limited, thus keeping the air cylinder 5 fixed.

[0028] Reference Figure 6The positioning mechanism 4 also includes a movable block 46 and a pull rod 48. The movable block 46 is slidably mounted on the cross rod 43, and the movable block 46 is hinged to the semi-circular ring 42 through a hinge rod 47. The movement of the movable block 46 can drive the hinge rod 47 to move, thereby causing the semi-circular ring 42 to squeeze the return spring 45, thus releasing the locking effect between the mounting groove 49 and the cylindrical block 41. The pull rod 48 is fixedly mounted on the semi-circular ring 42. By pulling the pull rod 48 on one semi-circular ring 42, one semi-circular ring 42 can be moved, causing the movable block 46 to drive the other semi-circular ring 42 to move, thereby causing the two semi-circular rings 42 to move away from each other.

[0029] Reference Figure 2 and Figure 3 The cylindrical tube 24 has a groove 25, which is used to avoid the steam flowing out of the through hole 26. The insert tube 1 has a through hole 26 that matches the air outlet 51. There are four sets of through holes 26 arranged around the circumference of the insert tube 1, so that the air injection tube 5 can adjust the orientation of the air outlet 51, thereby injecting steam into the soil through the through holes 26 at different positions. Both the connecting rod 1 21 and the connecting rod 23 have T-slots 27 that match the T-block 34. Since the T-block 34 matches the T-slot 27, the isolation plate 31 and the telescopic plate 33 can be connected by inserting the connecting rod 1 21 or the connecting rod 23 installed on the insert tube 1 at two different positions through the T-block 34.

[0030] Reference Figures 1 to 6 This isolation device for steam extraction remediation of organic polluted soil, through its connecting and enclosure mechanisms, can isolate soil areas of different shapes and sizes from other areas, thereby preventing pollutants in the soil to be remediated from escaping to other areas with steam. This improves the remediation effect of steam extraction remediation. In addition, the positioning mechanism facilitates the installation and positioning of the air injection cylinder inside the insert, and also allows for adjustment of the orientation of the air outlet of the air injection cylinder, further enhancing the effectiveness of the isolation device for steam extraction remediation.
