Description

Technical Field

[0001] This utility model relates to the field of geothermal energy, specifically an energy-saving auxiliary device for extracting geothermal water. Background Technology

[0002] Hydrothermal geothermal resources are one of the main types of geothermal resources. These resources are extracted from medium-deep geothermal water through natural channels or artificial drilling. During drilling, the geothermal water enters the casing through a screen pipe and is then pumped to the surface for reuse. The cooled water, having lost its heat, is then reinjected back into the extraction layer through a reinjection well. The primary energy consumption in hydrothermal geothermal resource development is concentrated on the pumps. These pumps are the power source for extracting underground hot water to the surface, circulating it within the system, and reinjecting it back into the underground reservoir. The energy consumption of the pumps largely determines the economic cost of operating a geothermal project. Reducing pump energy consumption will effectively improve the economic efficiency of geothermal projects, achieving low-carbon and energy-saving practices. Utility Model Content

[0003] To achieve the above objectives, the purpose of this utility model is to provide an energy-saving auxiliary device for geothermal water extraction, effectively reducing pump consumption during the geothermal water extraction process and improving the economic efficiency of the project. This utility model provides the following technical solution:

[0004] An energy-saving auxiliary device for geothermal water extraction includes a main pipe, a thermoelectric module, and a power module. The main pipe has an inlet and an outlet at each end, both connected to a water supply pipe. The thermoelectric module is connected to the power module, which is mounted on the main pipe. The thermoelectric module is made of semiconductor thermoelectric material. The upper half of the thermoelectric module is installed outside the main pipe, and the lower half is installed inside. The device operates as follows: the inlet and outlet of the main pipe are connected to the surface water supply pipe of the geothermal well. High-temperature geothermal water enters the main pipe and passes through the thermoelectric module. The upper half of the thermoelectric module, located inside the main pipe, is heated by the geothermal water, resulting in a higher temperature. The lower half, located outside the main pipe, is affected by the environment and thus has a lower temperature. A significant temperature difference exists between the upper and lower halves of the thermoelectric module, and this temperature difference can be maintained over a long period. The thermoelectric module, made of semiconductor thermoelectric material, generates current based on the thermoelectric effect. This current is transmitted to the power module, which drives the fluid within the main pipe to flow forward.

[0005] As a further embodiment of this utility model, both the inlet and outlet are connected to the water supply pipe via threads or flanges, ensuring a secure connection that is not easily detached, thereby guaranteeing smooth fluid flow.

[0006] As a further embodiment of this utility model: the upper and lower halves of the thermoelectric module are tightly embedded in the main body, making them less likely to fall off.

[0007] As a further embodiment of this utility model: a wire is connected to the thermoelectric module, and the thermoelectric module is connected to the power module through the wire to form a circuit. The wire has tensile and compressive strength.

[0008] As a further embodiment of this utility model: the power module includes a column and a fan blade. The column is a hollow column, welded inside the main body in the direction of the diameter of the main body. One end of the column is located outside the main body, and the other end is provided with a fan blade. An electric motor is installed inside the column. The thermoelectric module is connected to the electric motor through a wire. The current generated by the thermoelectric module can be input to the electric motor inside the column through the wire. The electric motor drives the fan blade to rotate, which can generate thrust and push the geothermal water forward.

[0009] As a further embodiment of this utility model: the fan blade is located at the center of the radial section of the main body, and the number of blades on the fan blade is three or more.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This product utilizes the natural thermal properties of geothermal water, driving its flow through a thermoelectric effect. This effectively reduces the power consumption of the circulating water pump, significantly lowering its energy consumption and improving economic efficiency. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1-3 This utility model provides an energy-saving auxiliary device for extracting geothermal water, comprising a main pipe 1, a thermoelectric module 2, and a power module. The main pipe 1 has an inlet and an outlet at its two ends, both of which are connected to a water supply pipe 6. The thermoelectric module 2 is connected to the power module, and the power module is installed on the main pipe 1. The thermoelectric module 2 is made of semiconductor thermoelectric material. The upper half of the thermoelectric module 2 is installed outside the main pipe 1, and the lower half is installed inside the main pipe 1. The usage process of this product is as follows: the inlet and outlet at both ends of the main pipe 1 are connected to the ground water supply pipe 6 of the geothermal well 4; the geothermal water 5 with a higher temperature enters the main pipe 1 and then passes through the thermoelectric module 2. The upper half of the thermoelectric module 2 is located inside the main pipe 1 and is heated by the geothermal water 5, thus having a higher temperature. The lower half of the thermoelectric module 2 is located outside the main pipe 1 and is affected by the environment, thus having a lower temperature. There is a large temperature difference between the upper and lower halves of the thermoelectric module 2, and this temperature difference can be maintained for a long time. Thermoelectric module 2 is made of semiconductor thermoelectric material. According to the thermoelectric effect, thermoelectric module 2 generates current, which is transmitted to the power module. The power module drives the fluid in the main body 1 to flow forward.

[0019] In one embodiment of this utility model, both the inlet and outlet are connected to the water pipe 6 via threads or flanges, ensuring a strong and secure connection that is not easily detached, thereby guaranteeing smooth fluid flow.

One end of the column 31 is located outside the main body 1, and the other end of the column 31 is provided with a fan blade 32. An electric motor is installed inside the column 31. The thermoelectric module 2 is connected to the electric motor through a wire 21. The current generated by the thermoelectric module 2 can be input to the electric motor inside the column 31 through the wire 21. The electric motor drives the fan blade 32 to rotate, which can generate thrust and push the geothermal water 5 forward.

[0023] In one embodiment of this utility model, the fan blade 32 is located at the center of the radial section of the main pipe 1, and the fan blade 32 has three or more blades, which provides strong driving force and ensures the smooth flow of geothermal water 5.

[0024] In one embodiment of this utility model, a main body 1 may be provided with multiple thermoelectric modules 2 and power modules.

[0025] In one embodiment of this utility model, the thermoelectric module 2 and the power module are both located on one side of the main pipe 1; after the geothermal water 5 enters the main pipe 1, it first passes through the thermoelectric module 2 and then through the power module, so that the device can work smoothly.
