Description

Technical Field

[0001] The invention relates to the technical field of geothermal reinjection, and in particular to a geothermal tail water reinjection system. Background Art

[0002] Geothermal resources are a kind of pollution-free, renewable clean energy. Compared with traditional fossil energy, they have many advantages such as abundant reserves, low carbon and environmental protection. For hydrothermal geothermal resources, heat energy is used by extracting groundwater, but groundwater is not inexhaustible. Geothermal recharge is a measure to avoid thermal and chemical pollution caused by direct discharge of geothermal wastewater, and plays an important role in maintaining heat storage pressure and ensuring the technical conditions for the exploitation of geothermal fields.

[0003] In the patent document with the publication number CN114349226A, a geothermal tail water efficient reinjection system is proposed, which adds an appropriate amount of corrosion inhibitor, scale inhibitor, and bactericide into the sedimentation tank to remove microorganisms in the water, prevent geothermal tail water from corroding metal pipes and metal devices, and inhibit scale formation; when the actual reinjection volume of the reinjection well does not match the theoretical demand, the storage sedimentation tank connected to the external water source plays an auxiliary reinjection role to achieve 100% reinjection of geothermal tail water. However, the geothermal tail water efficient reinjection system often reduces the reinjection capacity of the well due to blockage during the reinjection process. Summary of the invention

[0007] Preferably, the rotating tube passes through the filter box and is slidably connected to the inner wall of the filter box, the centrifuge tubes are symmetrically distributed on the outer surface of the rotating tube at equal intervals, the diameter of the end of the centrifuge tube away from the rotating tube is smaller than the diameter of the end close to the rotating tube, and the electromagnet generates magnetism and attracts the side close to the permanent magnet block. The top of the filter box extends to the interior of the filter box and is rotatably connected to the interior of the filter box. After water enters the centrifuge tube from the rotating tube, it will be thrown out of the centrifuge tube at high speed under the action of centrifugal force, impacting the filter box, impurities are filtered out, and water passes through the filter box.

[0008] Preferably, the material of the airbag is rubber, an upper contact is fixedly installed on the inner top of the airbag, a lower contact is fixedly installed on the inner bottom of the airbag, a ventilation pipe is fixedly connected to the bottom of the airbag, and an alarm is fixedly installed on the left side of the top of the geothermal platform. When the filter box retains more impurities and forms a blockage, the impurities in the box are difficult to remove, and the pressure in the filter box further increases. The airbag contracts under the action of pressure, and the upper contact contacts the lower contact. When the airbag contracts under the action of pressure, the pressure inside the airbag will be transmitted along the ventilation pipe, and the pneumatic alarm will receive the transmitted gas and sound an alarm to remind the inspection of the geothermal well.

[0009] Preferably, the upper contact and the lower contact are opposite to each other and do not touch each other, the electromagnet is electrically connected to the spiral coil through the upper contact and the lower contact, the alarm is a pneumatic alarm, the upper contact and the lower contact are in contact, then the spiral coil is connected to the electromagnet to form a closed loop, the spiral coil continuously cuts the magnetic flux lines of the permanent magnet block to generate an induced current, and the electromagnet is powered, so that the electromagnet generates magnetism and is attracted to the opposite poles of the permanent magnet block and approaches each other.

[0010] Preferably, the water inlet pipe extends to the interior of the rotating tube, a filter screen is installed on the inner top of the geothermal well, a motor is fixedly installed on the top right side of the geothermal platform, the output end of the motor is connected to a transmission shaft, the end of the transmission shaft away from the motor is fixedly connected to a worm, and the front side of the worm is connected to a worm wheel.

[0011] Preferably, the worm is meshingly connected with the worm wheel, the center of the worm wheel is fixedly connected to the rotating tube, the output shaft of the motor drives the transmission shaft to rotate, the transmission shaft drives the worm to rotate, by starting the motor, the output shaft of the motor drives the transmission shaft to rotate, the transmission shaft drives the worm to rotate, the worm drives the worm wheel meshing with it to rotate, and the worm wheel drives the rotating tube to start rotating at high speed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the geothermal tail water reinjection system, when the filter box retains a lot of impurities and forms a blockage, the impurities in the box are difficult to remove, and the pressure in the filter box further increases. The airbag contracts under the pressure, and the upper contact and the lower contact are in contact. At this time, the spiral coil is connected with the electromagnet to form a closed loop. The spiral coil continuously cuts the magnetic flux lines of the permanent magnet block to generate an induced current, and the electromagnet is powered. The electromagnet generates magnetism and attracts the opposite poles of the permanent magnet block and approaches each other. After the electromagnet contacts the permanent magnet block, the rotating tube drives the filter box to rotate synchronously. At this time, the spiral coil no longer cuts the magnetic flux lines of the permanent magnet block, and the magnetism on the electromagnet disappears and falls under the action of gravity. This reciprocating process drives the filter box to reciprocate and contract and shake, and shakes the impurities trapped on the surface to the bottom of the filter box to prevent blockage. There is no need to frequently replace the filter box, so that the filtration can be carried out continuously and effectively.

[0013] 2. In the geothermal tail water reinjection system, when the airbag contracts under pressure, the pressure inside the airbag will be transmitted along the vent pipe. The pneumatic alarm will receive the transmitted gas and sound an alarm to remind the geothermal well to be checked. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A rotating tube 502 is connected to the top of the box body 5, a centrifugal tube 503 is fixedly connected to the bottom of the outer surface of the rotating tube 502, a filter box 505 is connected to the bottom of the box body 5, a permanent magnet 504 is fixedly connected to the bottom of the rotating tube 502, a bottom plate 506 is fixedly connected to the bottom of the filter box 505, an electromagnet 508 is fixedly connected to the top center of the bottom plate 506, an air bag 507 is fixedly installed on the left side of the top of the bottom plate 506, a spiral coil 509 is installed inside the bottom plate 506, the rotating tube 502 penetrates the box body 5 and is slidably connected to the inner wall of the box body 5 penetrated, the centrifugal tubes 503 are symmetrically distributed on the outer surface of the rotating tube 502 at equal intervals, the diameter of one end of the centrifugal tube 503 away from the rotating tube 502 is smaller than the diameter of the other end close to the rotating tube 502, the electromagnet 508 generates magnetism and attracts the side close to the permanent magnet 504, and the top of the filter box 505 extends to the inside of the box body 5 and is rotatably connected to the inside of the box body 5.

The electromagnet 508 is electrically connected to the spiral coil 509 through the upper contact 5071 and the lower contact 5072. When the filter box 505 retains a lot of impurities and forms a blockage, the impurities in the box body 5 are difficult to remove, and the pressure in the filter box 5 is further increased. The airbag 507 contracts under the action of pressure, and the upper contact 5071 and the lower contact 5072 are in contact. At this time, the spiral coil 509 is connected to the electromagnet 508 to form a closed loop.

[0023] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a technical solution: a geothermal tail water reinjection system, comprising a geothermal well 1 and a geothermal platform 2, wherein the geothermal well 1 is arranged at the bottom of the geothermal platform 2, a box body 5 is fixedly installed on the top of the interior of the geothermal well 1, a water inlet pipe 4 is connected to the top of the box body 5, the water inlet pipe 4 extends to the interior of a rotating tube 502, and a filter screen 6 is installed on the top of the interior of the geothermal well 1.

[0024] A motor 3 is fixedly installed on the top right side of the geothermal platform 2, and a transmission shaft 301 is connected to the output end of the motor 3, and a worm 302 is fixedly connected to the end of the transmission shaft 301 away from the motor 3, and a worm wheel 303 is connected to the front of the worm 302, and the worm 302 is meshed with the worm wheel 303, and the center of the worm wheel 303 is fixedly connected to the rotating tube 502. By starting the motor 3, the output shaft of the motor 3 drives the transmission shaft 301 to rotate, and the transmission shaft 301 drives the worm 302 to rotate, and the worm 302 drives the worm wheel 303 meshed with it to rotate, and the worm wheel 303 drives the rotating tube 502 to start high-speed rotation. Because the diameter of the end of the centrifugal tube 503 away from the rotating tube 502 is smaller than the diameter of the end close to the rotating tube 502, after water enters the centrifugal tube 803 from the rotating tube 502, it will be thrown out of the centrifugal tube 503 at high speed under the action of centrifugal force, and impact on the filter box 505, impurities are filtered out, and water passes through the filter box 505.

[0025] The top of the box body 5 is connected to a rotating tube 502, the bottom of the outer surface of the rotating tube 502 is fixedly connected to a centrifugal tube 503, the bottom of the box body 5 is connected to a filter box 505, the bottom of the rotating tube 502 is fixedly connected to a permanent magnet block 504, the bottom of the filter box 505 is fixedly connected to a bottom plate 506, the top center of the bottom plate 506 is fixedly connected to an electromagnet 508, an air bag 507 is fixedly installed on the left side of the top of the bottom plate 506, and a spiral coil 509 is installed inside the bottom plate 506. The rotating tube 502 passes through the box body 5 and is connected to the box body 5. The body 5 is slidably connected to the inner wall through which it is penetrated, and the centrifuge tubes 503 are symmetrically distributed on the outer surface of the rotating tube 502 at equal intervals. The diameter of the end of the centrifuge tube 503 away from the rotating tube 502 is smaller than the diameter of the end close to the rotating tube 502. After the electromagnet 508 generates magnetism, it attracts the side close to the permanent magnet block 504. The top of the filter box 505 extends to the inside of the box 5 and is rotatably connected to the inside of the box 5. When the filter box 505 retains a lot of impurities and forms a blockage, the impurities in the box 5 are difficult to remove, and the pressure in the filter box 5 is further increased.

[0026] The material of the airbag 507 is rubber, and an upper contact 5071 is fixedly installed on the inner top of the airbag 507, and a lower contact 5072 is fixedly installed on the inner bottom of the airbag 507. The upper contact 5071 and the lower contact 5072 are opposite to each other and do not touch each other.

A ventilation pipe 5073 is fixedly connected to the bottom of the airbag 507, and an alarm 5074 is fixedly installed on the top left side of the geothermal platform 2. The alarm 5074 is a pneumatic alarm. When the airbag 507 contracts under pressure, the pressure inside the airbag 507 will be transmitted along the ventilation pipe 5073. The pneumatic alarm 5074 will receive the transmitted gas and will sound an alarm to remind the inspection of the geothermal well.

[0027] When in use, when the filter box 505 retains a lot of impurities and forms a blockage, the impurities in the box body 5 are difficult to remove, and the pressure in the filter box 5 is further increased. The airbag 507 contracts under the pressure, and the upper contact 5071 and the lower contact 5072 are in contact. At this time, the spiral coil 509 is connected with the electromagnet 508 to form a closed loop. The spiral coil 509 continuously cuts the magnetic flux lines of the permanent magnet block 504 to generate an induced current, which supplies power to the electromagnet 508. Then, the electromagnet 508 generates magnetism and contacts the permanent magnet block 504. 4 Opposite poles attract each other and approach each other. After the electromagnet 508 contacts the permanent magnet block 504, the rotating tube 502 drives the filter box 505 to rotate synchronously. At this time, the spiral coil 509 no longer cuts the magnetic flux lines of the permanent magnet block 504, and the magnetism on the electromagnet 508 disappears and falls under the action of gravity. This reciprocating process drives the filter box 505 to reciprocate and contract and shake, and the impurities trapped on the surface are shaken off to the bottom of the filter box 5, preventing the occurrence of clogging problems. There is no need to frequently replace the filter box 505, so that the filtration can be continuously and effectively carried out.
