Description

Technical Field

[0001] The invention relates to the technical field of geothermal energy, and in particular to a geothermal collection device. Background Art

[0002] Geothermal energy is natural heat energy extracted from the earth's crust. This energy comes from the molten rock inside the earth and exists in the form of heat. The use of geothermal energy can contribute to sustainable energy supply, reduce dependence on traditional energy, and reduce the impact on the environment. Geothermal harvesting is a way of utilizing heat energy by directly introducing geothermal flow into the heating system using geothermal energy as the main heat source, or transferring the heat energy of geothermal flow to the circulating water of the heating system through a heat exchanger. The geothermal flow does not directly enter the heating system.

Cold water is passed into the underground heat reservoir through the outer tube of the casing, and the cold water is heated by geothermal energy before being pumped away through the inner tube of the casing. However, geothermal collection devices do not have heat preservation and heating functions. After extracting geothermal energy, the hot water stored in the device will gradually cool down, resulting in a large loss of geothermal energy and reducing the heat extraction efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figure 1As shown, it is a preferred embodiment of the geothermal collection device of the present invention, and this geothermal collection device can be used to extract geothermal energy. The above-mentioned geothermal collection device includes: a collection mechanism 1, a conveying mechanism 2 and a heat extraction mechanism 3. The collection mechanism 1 includes a gas storage member 11 and a liquid storage member 12, and the liquid storage member 12 is arranged in the gas storage member 11, the gas storage member 11 is used to store steam, and the liquid storage member 12 is used to store high-temperature liquid after heating. The conveying mechanism 2 is used to transport liquid and steam, and it includes a first liquid conveying pipeline 21, a second liquid conveying pipeline 22 and a steam conveying pipeline 23, and a liquid extraction member 24 is arranged on the second liquid conveying pipeline 22. The heat extraction mechanism 3 includes a box body 31, and the box body 31 is provided with: a liquid inlet, a liquid outlet and an exhaust port. One end of the first liquid conveying pipeline 21 is connected to an external water supply device, and the other end is connected to the liquid inlet. The first liquid conveying pipeline 21 is used to transport low-temperature liquid into the box body 31 to use geothermal energy for heating. One end of the second liquid delivery pipe 22 is connected to the liquid storage part 12, and the other end is connected to the liquid outlet. The high-temperature liquid after absorbing geothermal energy can be delivered to the liquid storage part 12 for storage through the liquid extraction part 24 on the second liquid delivery pipe 22. One end of the steam delivery pipe 23 is connected to the gas storage part 11, and the other end is connected to the exhaust port, which is used to deliver high-temperature steam to the gas storage part 11. A liquid heating component 32 and a gas collecting component 33 are arranged in the box body 31, and a heat extraction component 34 for extracting geothermal energy is also arranged on the outer wall of the box body 31. The liquid heating component 32 is connected to the liquid inlet and the liquid outlet. The low-temperature liquid input from the liquid inlet is heated in the liquid heating component 32 to become a high-temperature liquid and then discharged from the liquid outlet. The heat required for liquid heating is transferred to the liquid heating component 32 through the box body 31 after extracting geothermal energy through the heat extraction component 34. The liquid heating component 32 is provided with an air outlet. During the heating process, the liquid will vaporize and generate steam, which is collected by the gas collecting component 33. The gas collecting component 33 is connected to the exhaust port, so the steam collected by the gas collecting component 33 can be sent to the gas storage component 11 from the exhaust port. Since the gas storage component 11 stores high-temperature steam, the high-temperature liquid stored in the liquid storage component 12 can be continuously heated and insulated. The high-temperature liquid will not lose a large amount of geothermal energy and cool down, and the heat extraction efficiency is high. Moreover, the high-temperature steam is generated during the liquid heating process, and no additional supply is required, which is energy-saving and environmentally friendly.

[0048] like Figure 2 , Figure 3 As shown, the gas storage member 11 is a relatively large tank body, with an air inlet at the bottom and an air outlet at the top, which can be connected to a steam collection device so that the steam can be reused. A mounting ring 111 is provided inside the gas storage member 11, and the mounting ring 111 is connected to the inner wall of the gas storage member 11 through a connector.

[0049] like Figure 4As shown, the liquid storage component 12 is a relatively small tank body arranged inside the gas storage component 11, and the upper end of the liquid storage component 12 is open. Specifically, the liquid storage component 12 is composed of a cylindrical upper half and a spherical shell lower half. The liquid storage component 12 is connected to the mounting ring 111, that is, the open end of the liquid storage component 12 is fixedly connected to the mounting ring 111. The bottom of the liquid storage component 12 has a liquid inlet, and one end of the second liquid delivery pipeline 22 will extend into the interior of the gas storage component 11 and connect to the liquid inlet of the liquid storage component 12. The side wall of the high-temperature liquid storage component 12 has a liquid outlet, and the high-temperature liquid inside the liquid storage component 12 is delivered to the water-demanding equipment through the liquid outlet.

[0050] Furthermore, the outer wall of the liquid storage part 12 is provided with a plurality of second heat conducting sheets 121 at intervals along the circumference thereof. Specifically, the plurality of second heat conducting sheets 121 are evenly spaced along the circumference of the outer wall of the cylindrical upper half of the liquid storage part 12. A heat conducting plate 122 is also provided at the bottom of the liquid storage part 12. The heat conducting plate 122 includes an annular plate provided at the connection between the upper half and the lower half of the liquid storage part 12, and a strip plate along the surface of the spherical shell-shaped lower half. High-temperature steam is stored in the gas storage part 11. The heat of the high-temperature steam can be transferred to the high-temperature liquid in the liquid storage part 12 more quickly through the second heat conducting sheets 121 and the heat conducting plate 122, and the heat preservation and heating effect is better.

[0051] Of course, in other embodiments, the second heat conducting sheet 121 and the heat conducting plate 122 may not be provided, and the high-temperature liquid inside may be kept warm and heated by heat conduction through the surface of the liquid storage member 12 .

[0052] In other embodiments, the shapes of the gas storage member 11 and the liquid storage member 12 may also be other shapes such as a square shell.

[0053] like Figure 6 As shown, the delivery mechanism 2 includes a first liquid delivery pipeline 21, a second liquid delivery pipeline 22 and a steam delivery pipeline 23. In this embodiment, the liquid inlet, the liquid outlet and the exhaust port are all opened on the side wall of the box body 31, and the liquid inlet, the liquid outlet and the exhaust port are sequentially arranged from bottom to top on the side wall of the box body 31. Correspondingly, the first liquid delivery pipeline 21, the second liquid delivery pipeline 22 and the steam delivery pipeline 23 are all "L" shaped, which is convenient for corresponding connection with the liquid inlet, the liquid outlet and the exhaust port.

[0054] One end of the first liquid delivery pipe 21 is connected to an external water supply device, and the other end is connected to a liquid inlet. The first liquid delivery pipe 21 is used to deliver low-temperature liquid provided by the external water supply device to the liquid inlet of the housing 31. One end of the second liquid delivery pipe 22 is connected to the liquid storage part 12, and the other end is connected to the liquid outlet. The high-temperature liquid after absorbing geothermal energy can be delivered to the liquid storage part 12 through the liquid extraction part 24 on the second liquid delivery pipe 22. Since the first liquid delivery pipe 21 delivers low-temperature liquid from top to bottom, and the second liquid delivery pipe 22 delivers high-temperature liquid from bottom to top, the second liquid delivery pipe 22 needs to be powered by the liquid extraction part 24 to deliver the high-temperature liquid to the liquid storage part 12. In this embodiment, the liquid extraction part 24 is preferably a water pump.

[0055] In addition, the delivery mechanism 2 further includes a liquid delivery component 25, which includes: a liquid delivery pipeline 251 and a control valve 252. One end of the liquid delivery pipeline 251 is connected to the liquid outlet of the liquid storage part 12, and the other end is connected to the water-using equipment. The control valve 252 is arranged on the liquid delivery pipeline 251 to control the on-off of the liquid delivery pipeline 251. By arranging the liquid delivery component 25, the high-temperature liquid in the liquid storage part 12 can be delivered to the water-using equipment at any time.

[0056] Further, such as Figure 7 As shown, the heat extraction assembly 34 includes a plurality of heat transfer grid sheets 341 disposed on the outer wall of the box body 31, and the surrounding geothermal energy is extracted through the plurality of heat transfer grid sheets 341, and the heat is transferred to the box body 31, and then the low-temperature liquid in the box body 31 is heated by the heat. In this embodiment, the heat transfer grid sheet 341 is only disposed on one side wall of the box body 31. Of course, in other embodiments, the heat transfer grid sheet 341 can also be disposed on any one or more side walls of the box body 31.

[0057] like Figure 8 As shown, the liquid heating component 32 includes: a liquid storage tube 321 and a drainage tube 322. The liquid storage tube 321 is connected to the liquid inlet, and the liquid storage tube 321 is used to contain low-temperature liquid. And a plurality of air outlets are provided on the liquid storage tube 321 for discharging steam. The drainage tube 322 is an "L"-shaped tube, one end of which is connected to the liquid storage tube 321, and the other end is connected to the liquid outlet. After the low-temperature liquid enters the liquid storage tube 321, it is gradually heated. After the heating is completed, the high-temperature liquid enters the second liquid delivery pipeline 22 from the liquid outlet through the drainage tube 322. Steam is generated during the heating process and is discharged from the air outlet into the gas collecting component 33.

[0058] Furthermore, the liquid heating component 32 also includes a plurality of first heat conducting sheets 323 disposed on the outer wall of the liquid storage tube 321. The heat conducting sheets can quickly transfer the heat of the box 31 to the liquid storage tube 321. In this embodiment, the first heat conducting sheets 323 are disposed on both the front and rear sides and the bottom of the liquid storage tube 321.

[0059] The gas collecting assembly 33 includes: a gas collecting hopper 331 and a guide plate 332. The gas collecting hopper 331 is arranged on the top of the box body 31, and one end of the guide plate 332 is connected to the liquid heating assembly 32, and the other end is connected to the gas collecting hopper 331. The guide plate 332 plays a drainage role, and introduces the steam into the gas collecting hopper 331 for collection.

[0060] like Figure 5 As shown, the geothermal collection device further includes a steam power generation component 4, which is connected to the gas collection component 33 and electrically connected to the liquid extraction component 24. The steam power generation component 4 can generate electricity using steam and supply power to the liquid extraction component 24, that is, the geothermal collection device can generate electricity and supply power by itself without external power supply, which is energy-saving and environmentally friendly.

[0061] Specifically, the steam power generation component 4 includes: a steam turbine generator 41, a transformer 42 and an electric control switch 43. The steam turbine generator 41 is arranged on the top surface of the box body 31 and is connected to the gas collecting component 33. The gas collecting component 33 sends steam into the steam turbine generator 41. The steam turbine generator 41 is electrically connected to the transformer 42, and the electricity generated by the steam turbine generator 41 is transformed by the transformer 42 to meet the use requirements of the liquid extraction component 24. The transformer 42 is electrically connected to the electric control switch 43, and the electric control switch 43 is electrically connected to the liquid extraction component 24. The electric control switch 43 controls the on and off of the circuit, that is, controls whether to supply power to the liquid extraction component 24.

[0062] The steam power generation component 4 also includes a control center, which is connected to the steam turbine generator 41, the transformer 42 and the power control switch 43, and can control the steam turbine generator 41, the transformer 42 and the power control switch 43. The control center includes but is not limited to a server, a computer, etc.

[0063] The working process of the geothermal collection device provided in this embodiment is described as follows:

[0064] The external water supply device provides low-temperature liquid and delivers it to the liquid inlet through the first liquid delivery pipe 21, and then enters the liquid storage pipe 321. The multiple heat transfer grid plates 341 of the heat extraction component 34 extract geothermal energy and transfer the heat energy to the liquid storage pipe 321 through the box body 31 and the first heat conductive plate 323, and heat the low-temperature liquid in the liquid storage pipe 321. During the heating process, the liquid will be vaporized into steam and discharged from the liquid storage pipe 321 through the exhaust hole, and enter the gas collecting hopper 331 under the guidance of the guide plate 332. Part of the steam in the gas collecting hopper 331 is used for power generation by the steam turbine generator 41, and the steam turbine generator 41 can power the liquid extraction component 24 after power generation, and the other part enters the steam delivery pipe 23 through the exhaust port, and then is delivered to the gas storage component 11.

[0065] When the low-temperature liquid is heated, the high-temperature liquid is transported from the liquid storage tube 321 through the drainage tube 322 from the liquid outlet to the second liquid delivery pipe 22 through the liquid extraction member 24, and then sent to the liquid storage member 12 for storage. After the high-temperature liquid is stored in the liquid storage member 12, the steam in the gas storage member 11 can transfer heat to the liquid storage member 12 through the second heat conducting sheet 121 and the heat conducting plate 122, so as to continuously heat and insulate the high-temperature liquid stored in the liquid storage member 12.

[0066] When the water-using equipment has a water demand, the control valve 252 is opened, and the high-temperature liquid stored in the liquid storage member 12 is delivered to the water-using equipment along the liquid delivery pipeline 251 .

[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
