It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In order to solve the technical problem of how to increase the soil temperature during the soil remediation process, the present invention provides a soil remediation system that uses a heat pipe 310 to increase the ambient temperature deep in the soil, accelerates the reproduction rate of bacteria, and thus accelerates the efficiency of soil organic pollution control.

[0026] It should be noted that the soil remediation system of the present invention is used for but not limited to soil organic pollution control, etc. For the convenience of explanation, in the present invention, only the application of the soil remediation system to soil organic pollution control is used as an example for explanation. The principles of applying the soil remediation system to other types of equipment are essentially the same as those applied to soil organic pollution control, and will not be elaborated here.

[0027] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a soil remediation system in one embodiment of the present invention. The soil remediation system includes a liquid supply component 100, an air supply component 200, and a heat exchange component 300. The liquid supply component 100 includes a liquid supply pipe 110 and a liquid supply pump 120. One end of the liquid supply pipe 110 extends into the soil, and the liquid supply pump 120 is connected to the other end of the liquid supply pipe 110 to pressurize the bacterial solution into the soil through the liquid supply pipe 110. The air supply component 200 includes an air supply pipe 210 and an air pump 220. One end of the air supply pipe 210 extends into the soil, and the air pump 220 is connected to the other end of the air supply pipe 210 to pressurize air into the soil through the air supply pipe 210. The heat exchange component 300 includes a heat pipe 310 and a heating device 320. The heat pipe 310 is inserted into the soil, and the heating device 320 is used to heat the heat pipe 310.

[0028] In this embodiment, liquid pump 120 pressurizes bacterial solution into the soil through liquid supply pipe 110, while air pump 220 pressurizes air into the soil through air supply pipe 210. This creates an aerobic environment deep within the soil that supports bacterial growth, allowing the bacteria to decompose organic pollutants in the soil. Heating device 320 heats heat pipe 310, thereby increasing the ambient temperature deep within the soil, accelerating bacterial growth and thus improving the efficiency of soil organic pollution control.

[0029] In some embodiments, there are multiple heat pipes 310 , and the multiple heat pipes 310 are arranged side by side.

[0030] In this embodiment, the use of multiple heat pipes 310 can increase the contact area between the soil and the heat pipes 310, which can increase the temperature of the soil more quickly and expand the temperature increase range of the soil.

[0031] In some embodiments, the heating device 320 includes a plurality of heat exchange fins 321 , which are arranged along the length direction of the heat pipe 310 . The heat exchange fins 321 are mounted on the ground, and the heat pipe 310 passes through each heat exchange fin 321 in sequence.

[0032] In this embodiment, if the ground temperature is high, the heat in the air is absorbed by the heat exchange fins 321 and the heat is transferred to the deep soil through the heat pipes 310, so that the soil temperature rises.

[0033] Any embodiment of the heating device 320 is feasible as long as it can generate heat to heat the heat pipe 310 . In some embodiments, the heating device 320 includes a combustion furnace, which is used to heat the heat pipe 310 .

[0034] In this embodiment, the heat pipe 310 is heated by the heat generated by the combustion of fuel inside the combustion furnace.

[0035] In some embodiments, the end of the heat pipe 310 extending into the soil has a tapered surface.

[0036] In this embodiment, since the end of the heat pipe 310 extending into the soil has a tapered surface, the resistance of the heat pipe 310 inserted into the soil can be reduced, making it easier for the heat pipe 310 to extend into the soil.

[0037] In some embodiments, the liquid supply assembly 100 includes a liquid distribution pipe 130 , and there are multiple liquid supply pipes 110 . The multiple liquid supply pipes 110 are all connected to the liquid distribution pipe 130 , and the liquid supply pump 120 is connected to the multiple liquid supply pipes 110 via the liquid distribution pipe 130 .

[0038] In this embodiment, the liquid supply pump 120 pressurizes the bacterial liquid into the liquid distribution pipe 130 , and further can deliver the bacterial liquid to each liquid supply pipe 110 .

[0039] In some embodiments, a plurality of liquid outlet holes 111 are formed on the sidewall of the liquid dispensing tube 130 along its length.

[0040] In this embodiment, since a plurality of liquid outlet holes 111 are formed on the side wall of the liquid distribution pipe 130 along its length, the bacterial liquid can penetrate into the soil at different depths through the liquid outlet holes 111 .

[0041] On the basis of the above embodiments, in some embodiments, the liquid dispensing tube 130 is arranged at an angle.

[0042] In this embodiment, the dispensing tube 130 is tilted to increase the horizontal span of the dispensing tube 130 , thereby being able to transport the bacterial liquid in a larger area.

[0043] In some embodiments, the liquid supply assembly 100 further includes a bacteria liquid tank 140 , and the liquid inlet end of the liquid supply pump 120 is connected to the bacteria liquid tank 140 .

[0044] In this embodiment, bacterial powder and water can be mixed with each other in the bacterial liquid tank 140 to form bacterial liquid, which can then be pressure-transported to the liquid supply pipe 110 by the liquid supply pump 120 .

[0045] In some embodiments, the air supply assembly 200 further includes an air distribution pipe 230 . There are multiple air supply pipes 210 , and the multiple air supply pipes 210 are all connected to the air distribution pipe 230 . The air pump 220 is connected to the air supply pipe 210 via the air distribution pipe 230 .

[0046] In this embodiment, the air pump 220 delivers air into the air distribution pipe 230 , and then pressurizes the gas into each air supply pipe 210 through the air distribution pipe 230 , thereby delivering air into the soil over a large area.

[0047] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0048] Liquid supply pump 120 pressurizes bacterial liquid into liquid distribution pipe 130, which in turn can deliver bacterial liquid to each liquid supply pipe 110, thereby widely distributing bacterial liquid into the soil. Air pump 220 delivers air into air distribution pipe 230, which in turn, through air distribution pipe 230, can pressurize air into each air supply pipe 210, thereby widely distributing air into the soil. This creates an aerobic environment deep in the soil that supports bacterial growth, allowing bacteria to decompose organic pollutants in the soil. Heating device 320 heats heat pipe 310, thereby increasing the ambient temperature deep in the soil, accelerating bacterial growth and thus improving the efficiency of soil organic pollution control.

[0049] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
