Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A geothermal energy well energy-saving circulation collection device includes a placement plate 1. From left to right, a filter box 2, a flash chamber 3, a turbine 4, a generator 5, and a storage tank 6 are fixedly connected to the top of the placement plate 1. A waste heat recovery assembly 7 is provided on the rear side of the placement plate 1. A filter screen 8 is installed inside the filter box 2. A disassembly and assembly mechanism 9 is provided inside the filter box 2, which includes:

[0027] The assembly 91 includes a support block 911 fixedly installed on the inner wall of the filter box 2 and an installation rod 912 slidably installed inside the filter box 2. The surface of the installation rod 912 is slidably connected to the inside of the support block 911. A connecting plate 913 is fixedly connected to one end of the installation rod 912. A control plate 914 is fixedly connected to one side of the connecting plate 913. An installation spring 915 is fixedly connected to the surface of the installation rod 912. One end of the installation spring 915 is fixedly connected to the inner wall of the filter box 2. A connecting groove 916 is provided on the top of the support block 911.

[0028] The connecting component 92 is located at the bottom of the filter plate 8.

[0029] The flash chamber 3 is equipped with a flash evaporator, which is a highly efficient liquid concentration device. Its core principle is to use instantaneous heating to rapidly evaporate the solvent, thereby achieving the concentration and separation of substances.

[0030] A turbine is a device that uses changes in the pressure of steam or gas to convert them into mechanical energy. Its main function is to increase the intake air volume by compressing air, thereby increasing the output power of the engine.

[0031] Generator 5 is a device that converts mechanical energy into electrical energy. Its basic working principle is based on the law of electromagnetic induction. When a conductor moves in a magnetic field, an electromotive force is generated inside the conductor. This process mainly consists of two parts: the change of the magnetic field and the movement of the conductor. Generators are usually composed of components such as stator, rotor, end cover and bearings. The rotor rotates in the stator and cuts the magnetic lines of force to generate an induced electromotive force, and then the current is led out through the terminal.

[0032] The turbine inside turbine 4 is connected to the rotor of generator 5 via a shaft, and generator 5 is connected to the battery inside battery storage box 6 via wires.

[0033] In this embodiment, the connecting component 92 includes a connecting block 921 installed at the bottom of the filter screen plate 8. The surface of the connecting block 921 is slidably connected to the inner surface of the connecting groove 916. The surface of the connecting block 921 is provided with an installation groove 922, and the inner surface of the installation groove 922 is engaged with one end of the installation rod 912.

[0034] When the spring 915 is not affected by external force, one end of the mounting rod 912 will always remain locked and fixed to the inner surface of the mounting groove 922.

[0035] Pulling the control plates 914 on both sides causes the connecting plate 913 and the mounting rod 912 to slide synchronously, thereby compressing the mounting spring 915. As the mounting rod 912 slides, one end of it slides inside the support block 911, causing one end of the mounting rod 912 to slide out of the mounting groove 922. This facilitates the quick removal of the filter screen 8 for replacement or cleaning. With the installation and removal mechanism 9, the filter screen 8 inside the filter box 2 can be quickly installed and removed. Under the influence of the elasticity of the mounting spring 915, one end of the mounting rod 912 will always be engaged with the inner surface of the mounting groove 922, thereby maintaining the stability of the filter screen 8 after installation.

[0036] In this embodiment, a sealing cover plate 10 is installed on the top of the filter box 2, and the right side of the filter box 2 is fixedly connected to the left side of the flash chamber 3 through the water outlet pipe 11.

[0037] In this embodiment, a water pumping pipe 12 is fixedly connected to the left side of the filter box 2, and one end of the water pumping pipe 12 extends through into the interior of the water pumping well.

[0038] In this embodiment, the right side of the flash chamber 3 is fixedly connected to the left side of the turbine 4 through the air inlet pipe 13, the right side of the turbine 4 is fixedly connected to the left side of the generator 5, and the right side of the generator 5 is fixedly connected to the left side of the battery storage box 6.

[0039] In this embodiment, the waste heat recovery assembly 7 includes a water storage tank 71 installed on the right side of the placement plate 1. A heat dissipation pipe 72 is fixedly connected inside the water storage tank 71. One end of the heat dissipation pipe 72 extends through to the outside of the water storage tank 71 and is fixedly connected to a connecting pipe 73. One end of the connecting pipe 73 is fixedly connected to the bottom of the turbine 4.

[0040] The outlet of the heat dissipation pipe 72 extends through to the outside of the rear side of the water storage tank 71, and the outlet is connected to the external condenser. The condenser converts the gas into liquid and discharges it back into the ground, realizing the energy-saving cycle collection of geothermal energy.

[0041] By installing a waste heat recovery component 7, the hot steam is further transported through the connecting pipe 73 and the heat dissipation pipe 72. The remaining geothermal energy of the hot steam is used to heat the cold water in the water storage tank 71, thus avoiding the loss of geothermal energy and realizing the full utilization of geothermal energy, achieving the effect of energy saving.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, geothermal water is first extracted from the well through the pumping pipe 12. The geothermal water then enters the filter box 2 through the pumping pipe 12, where it is filtered by the filter screen 8 inside the filter box 2 to remove impurities. The filtered geothermal water then enters the flash chamber 3 through the outlet pipe 11. The flash chamber 3 is equipped with a flash evaporator, which uses a pressure-reducing device to rapidly reduce the pressure of the geothermal water. As the pressure decreases, the steam in the geothermal water becomes supersaturated, causing some components to quickly convert into vapor, forming hot steam. This hot steam then enters the turbine 4 through the intake pipe 13, driving the turbine in the turbine 4 to rotate. The turbine 4 is connected to the generator 5, and the turbine is connected to the rotor of the generator 5 via a shaft. The rotor rotates in the stator, and the magnetic field on the rotor cuts the coils in the stator, generating an induced electromotive force. The electromotive forces of multiple coils are superimposed to form a voltage at the generator terminals, thus supplying power to the external storage tank 6. The storage tank 6 stores the electrical energy, while the flowing hot steam passes through the vortex... After the wheel converts kinetic energy into mechanical energy, the hot steam is discharged through connecting pipe 73 and enters heat dissipation pipe 72. At this time, heat dissipation pipe 72 is located inside water storage tank 71, which is filled with cool water. The heat dissipation pipe 72 dissipates the geothermal energy from the hot steam and heats the cool water. The heated water is stored in water storage tank 71 for later use. Finally, one end of heat dissipation pipe 72 is connected to an external condenser. After heat dissipation, the hot steam enters the condenser, where it is converted from gas to liquid and then discharged back into the ground. The geothermal energy is collected in a loop. After the work is completed, due to the long-term filtration of geothermal water by the filter plate 8, a lot of impurities are easily left on its surface. At this time, by pulling the control plates 914 on both sides, the connecting plate 913 and the mounting rod 912 slide synchronously, thereby compressing the mounting spring 915. As the mounting rod 912 slides, one end of it slides inside the support block 911, causing one end of the mounting rod 912 to slide out of the mounting groove 922, so that the filter plate 8 can be quickly removed for replacement or cleaning.
