DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] In order to solve the technical problem of how to increase the diffusion speed of oxidants in soil, the utility model provides an organic polluted soil remediation device, which can make the drug solution spread quickly in the soil.

[0024] It should be noted that the organic contaminated soil remediation device described in the utility model is used for but not limited to soil organic pollution control, etc. For the convenience of explanation, in the utility model, only the application of the organic contaminated soil remediation device to soil organic pollution control is used as an example for explanation, and the principle of applying the organic contaminated soil remediation device to other types of equipment is essentially the same as the principle applied to soil organic pollution control, which will not be repeated here.

[0025] See also Figure 1 , Figure 1 The schematic diagram of the structure of the organic contaminated soil remediation device in one embodiment of the utility model comprises a drug feeding component 100 and a water pumping component 200. The drug feeding component 100 comprises a first sleeve 110 and an introduction pipe 120. The first sleeve 110 is inserted into the soil. The introduction pipe 120 extends into the first sleeve 110 and introduces the drug solution into the soil. The water pumping component 200 comprises a second sleeve 210, an outlet pipe 220 and a water pump 230. The second sleeve 210 is inserted into the soil and is located near the first sleeve 110. One end of the outlet pipe 220 extends into the second sleeve 210. The water pump 230 is connected to the other end of the outlet pipe 220 to extract groundwater in the soil through the outlet pipe 220.

[0026] In this embodiment, the first sleeve 110 and the second sleeve 210 are firstly inserted into the soil, and the introduction pipe 120 extends into the first sleeve 110 and introduces the liquid medicine into the soil, so that the liquid medicine permeates into the soil. At the same time, one end of the outlet pipe 220 extends into the second sleeve 210, and the groundwater in the soil is extracted through the outlet pipe 220. Then, the diffusion speed of the liquid medicine in the soil is increased under the driving effect of the water flow, so that the liquid medicine can be quickly spread in the soil, shortening the treatment period of soil organic pollution.

[0027] In some embodiments, the drug feeding assembly 100 includes a first sealing member 130 , which is installed between the introduction tube 120 and the first sleeve 110 to seal a gap between the first sleeve 110 and the introduction tube 120 .

[0028] In this embodiment, since the first sealing member 130 seals the gap between the first sleeve 110 and the introduction tube 120, when the drug solution is introduced into the first sleeve 110 through the introduction tube 120, the pressure in the first sleeve 110 will increase, thereby promoting the drug solution to penetrate into the soil.

[0029] Any implementation of the first seal 130 that can seal the gap between the first sleeve 110 and the introduction tube 120 is feasible. In some embodiments, the first seal 130 includes a first annular airbag 131, which is sleeved on the outer wall of the introduction tube 120 and presses against the inner wall of the first sleeve 110.

[0030] In this embodiment, the first annular airbag 131 can be expanded by inflating air into the first annular airbag 131 until the first annular airbag 131 completely closes the gap between the first sleeve 110 and the introduction tube 120. When the first annular airbag 131 needs to be removed, the first annular airbag 131 can be deflated to reduce the volume of the first annular airbag 131, and then the first annular airbag 131 can be taken out from the gap between the first sleeve 110 and the introduction tube 120.

[0031] In some embodiments, the pumping assembly 200 includes a second sealing member 240 . The second sealing member 240 is installed between the outlet pipe 220 and the second sleeve 210 to seal a gap between the second sleeve 210 and the outlet pipe 220 .

[0032] In this embodiment, since the second sealing member 240 seals the gap between the second casing 210 and the outlet pipe 220, when groundwater is drawn into the second casing 210 through the outlet pipe 220, the pressure in the second casing 210 will be reduced, thereby promoting the movement of groundwater in the surrounding soil toward the second casing 210, thereby increasing the flow rate of groundwater in the soil.

[0033] Any implementation of the second sealing member 240 is feasible as long as it can seal the gap between the second sleeve 210 and the outlet tube 220. In some embodiments, the second sealing member 240 includes a second annular airbag 241, which is sleeved on the outer wall of the outlet tube 220 and presses against the inner wall of the second sleeve 210.

[0034] In this embodiment, the second annular airbag 241 can be expanded by inflating air into the second annular airbag 241 until the second annular airbag 241 completely closes the gap between the second sleeve 210 and the outlet tube 220. When the second annular airbag 241 needs to be removed, the second annular airbag 241 can be deflated to reduce the volume of the second annular airbag 241, and then the second annular airbag 241 can be taken out from the gap between the second sleeve 210 and the outlet tube 220.

[0035] In some of the embodiments, the organic contaminated soil remediation device further includes a circulation component 300 , which includes a water tank 310 . The water tank 310 receives groundwater discharged by the water pump 230 , and the end of the inlet pipe 120 away from the first casing 110 is connected to the water tank 310 .

[0036] In this embodiment, the water tank 310 is used to receive the groundwater discharged by the water pump 230, and the water in the water tank 310 can be re-introduced into the soil through the introduction pipe 120. In actual use, the medicine can be put into the water tank 310 and mixed with the water in the water tank 310 to form a medicine solution.

[0037] In some embodiments, the circulation component 300 further includes a water pressure pump 320 , which pressurizes the water in the water tank 310 to the introduction pipe 120 .

[0038] In this embodiment, the water pump 320 can ensure that the introduction pipe 120 has sufficient water outlet pressure, ensuring that the liquid medicine can be smoothly pressed into the soil.

[0039] In some embodiments, the pumping assembly 200 further includes a filter 250 , which is installed at a port of the inlet pipe 120 .

[0040] In this embodiment, the filter element 250 can prevent the mud and sand in the soil from entering the introduction pipe 120 along with the water flow.

[0041] On the basis of the above embodiments, in some embodiments, the filter element 250 includes a filter screen 251 , and the filter screen 251 is covered on the port of the introduction pipe 120 .

[0042] In this embodiment, the filter screen 251 is used to prevent mud and sand from entering the introduction pipe 120 .

[0043] In some embodiments, the depth to which the first casing 110 extends into the soil is less than the depth to which the second casing 210 extends into the soil.

[0044] In this embodiment, since the depth of the first casing 110 extending into the soil is less than the depth of the second casing 210 extending into the soil, the depth of the introduced liquid medicine is lower than the depth of the groundwater extraction, and under the action of gravity and water flow, the liquid medicine can be more fully diffused to all parts of the soil.

[0045] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0046] The first sleeve 110 and the second sleeve 210 are inserted into the soil, and the first seal 130 is installed between the introduction pipe 120 and the first sleeve 110 to close the gap between the first sleeve 110 and the introduction pipe 120. The introduction pipe 120 extends into the first sleeve 110 and introduces the liquid medicine into the soil, so that the pressure in the first sleeve 110 is increased, thereby promoting the liquid medicine to penetrate into the soil. One end of the outlet pipe 220 extends into the second sleeve 210, and the second seal 240 is installed between the outlet pipe 220 and the second sleeve 210 to close the gap between the second sleeve 210 and the outlet pipe 220. When the groundwater is drawn into the second sleeve 210 through the outlet pipe 220, the pressure in the second sleeve 210 will be reduced, thereby promoting the groundwater in the surrounding soil to move to the second sleeve 210, thereby increasing the flow rate of the groundwater in the soil. Furthermore, driven by the water flow, the diffusion rate of the liquid medicine in the soil is increased, so that the liquid medicine can be quickly spread in the soil, shortening the treatment period of soil organic pollution.

[0047] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
