Description

Technical Field

[0002] Suspended solids, chemical precipitates and gases generally exist in geothermal liquids. These impurities are likely to cause caking and blockage during the reinjection process, resulting in a decrease in reinjection efficiency. For example, the reinjection wells of porous sandstone thermal reservoirs have long been difficult to solve the problems of blockage caused by suspended solids and chemical scaling, which directly affects the sustainable development of geothermal resources.

[0003] A gas separation device for a geothermal reinjection well with the patent publication number CN112624460B relates to the technical field of gas separation, including a negative pressure pump and a sealed housing. An exhaust hole communicating the inside and outside is opened on the upper side of the sealed housing, and the exhaust hole is communicated with the intake port of the negative pressure pump. An intake hole and an outlet hole communicating the inside and outside are opened on the lower side of the sealed housing. The outside of the intake hole is connected to the upper end of the intake pipe, and the outside of the outlet hole is connected to the upper end of the outlet pipe. The height difference between the outlet pipe and the sealed housing is greater than 10 m. This gas separation device for a geothermal reinjection well performs negative pressure separation gas treatment on the reinjected water, avoids the gas phase blockage caused by the air in the reinjected water and affects the reinjection effect, and ensures the utilization rate of the heat in the heat energy area.

[0004] For the above gas separation device for a geothermal reinjection well, when in use, although the ultraviolet lamp is set to work to achieve the sterilization treatment of the water flowing through the sealed housing, avoiding the corrosion of the pipeline by bacteria or the blockage of the gaps in the thermal storage area, the existing one does not have the function of preventing blockage of the pipeline. Therefore, when the pipeline is used for a long time, due to the complex composition of the heat energy liquid, the pipeline may be blocked, resulting in frequent maintenance of the device and thus reducing the working efficiency.

[0015] The present invention provides a gas separation device for a geothermal reinjection well. It has the following beneficial effects:

[0016] (1) By setting up a stirring slag removal device, when the cylinder is started, under the push of the cylinder, the short rod slides in the rotating sleeve, causing the rotating sleeve to rotate. Through the cooperation of the stirring rod and the rotating shaft, the rotating piece is driven to rotate, keeping the impurities in the heat energy liquid in a suspended state all the time, solving the problem that impurities are likely to deposit at the bottom due to gravity to form hard lumps, which easily causes pipeline blockage.

[0017] (2) By setting up a collection and compaction device, when the cylinder moves, the sliding rod slides in the rotating sleeve, causing the rotating sleeve to rotate. Through the cooperation of the fixed block and the inclined throwing piece, the inclined throwing piece sweeps the impurities in the circular ring plate into the collection box, solving the blockage problem caused by impurity accumulation in the traditional static filter screen and maintaining high filtration efficiency. When the circular ring plate moves, the striking block moves away from the L table, enabling the compression spring and the compaction piece to cooperate, so that the compaction piece compresses the impurities in the collection box, solving the problems of insufficient compression and insufficient storage capacity of the static collection device, improving the single storage capacity, and reducing the frequency of replacing the collection box.

[0018] (3) By setting up a knocking device, when the compaction piece moves, it drives the blocking piece to move, causing the blocking piece to hit the L block to rotate. Through the cooperation of the L block and the return spring, the striking piece hits the collection box, making the impurities in various states in the collection box more evenly distributed in the collection box, solving the problem that the hardness and volume of the impurities in the collection box are different, resulting in uneven compaction due to the uneven height in the collection box, and improving the compaction effect.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 9 , an embodiment of the present invention is: A gas separation device for a geothermal reinjection well, including a sealing cylinder 1, the lower side of the sealing cylinder 1 is fixedly connected to the upper end of the water outlet pipe 4, the lower end of the water outlet pipe 4 is fixedly connected to the upper end of the check valve 3, the lower side of the sealing cylinder 1 is fixedly connected to the upper end of the water inlet pipe 2, the upper side of the sealing cylinder 1 is fixedly connected to the lower end of the negative pressure pump 5, a stirring slag removal device 6 for preventing impurities in the heat energy liquid from sinking to the bottom and caking is arranged inside the sealing cylinder 1, and the outer wall of the ultrasonic transmitter 9 is fixedly connected to the inner wall of the sealing cylinder 1.

[0031] Among them, the stirring slag removal device 6 includes a cylinder 601, a short rod 602, a rotating sleeve 603, a stirring rod 604, a rotating shaft 605, a rotating vane 606, a connecting rod 607, a circular ring plate 608 and a filter hole 609; the upper side of the closed cylinder 1 is fixedly connected to the lower end of the cylinder 601, and the outer end of the output end of the cylinder 601 is fixedly connected to the inner end of the short rod 602. When the cylinder 601 is started, the cylinder 601 pushes the short rod 602 downward. The inner wall of the closed cylinder 1 is rotatably connected to the outer wall of the stirring rod 604. The upper side of the stirring rod 604 is fixedly connected to the lower end of the rotating sleeve 603, and the outer wall of the short rod 602 fits with the spiral groove formed inside the rotating sleeve 603. When the short rod 602 moves, the short rod 602 slides in the spiral groove inside the rotating sleeve 603. The upper side of the stirring rod 604 is rotatably connected to the lower end of the rotating shaft 605. When the stirring rod 604 rotates, it drives the rotating shaft 605 to move synchronously. The outer wall of the rotating shaft 605 is fixedly connected to the inner wall of the rotating vane 606. When the rotating shaft 605 moves, it drives the rotating vane 606 to move. The outer wall of the output end of the cylinder 601 is fixedly connected to the inner wall of the connecting rod 607. When the cylinder 601 pushes downward, the connecting rod 607 moves downward. The outer end of the connecting rod 607 is fixedly connected to the inner end of the circular ring plate 608. When the connecting rod 607 moves downward, it drives the circular ring plate 608 to move downward synchronously. The circular ring plate 608 is provided with a filter hole 609.

[0032] In the present invention, by setting the stirring slag removal device 6 and starting the cylinder 601, under the push of the cylinder 601 at this time, the short rod 602 slides inside the rotating sleeve 603, causing the rotating sleeve 603 to rotate. Through the cooperation of the stirring rod 604 and the rotating shaft 605, the rotating vane 606 is driven to rotate, so that the impurities in the heat energy liquid are always in a suspended state, solving the problem that the impurities deposit at the bottom due to gravity to form hard lumps, which is likely to cause pipeline blockage.

[0033] In the present invention, by setting the stirring slag removal device 6, when the cylinder 601 pushes, the connecting rod 607 moves synchronously. Through the cooperation of the connecting rod 607 and the circular ring plate 608, the heat energy liquid enters the circular ring plate 608 and flows out from the filter hole 609, leaving the impurities in the heat energy liquid, solving the problem of a large content of impurities in the heat energy liquid, thereby prolonging the service life of the reinjection well.

[0034] During the operation of this embodiment: First, transport the device to the edge of the recharge well. Place the sealing cylinder 1 on the ground at the edge of the recharge well through the support legs on the outer wall of the sealing cylinder 1. Then, put the water inlet pipe 2 into the recharge well. The recharge water to be treated is injected into the sealing cylinder 1 through the water inlet pipe 2. The recharge water in the sealing cylinder 1 enters the water outlet pipe 4. Both the water inlet pipe 2 and the water outlet pipe 4 are filled with recharge water. Start the negative pressure pump 5. A negative pressure is generated inside the sealing cylinder 1, and the negative pressure range is 0 - 0.4 atmospheres. The suction force of the negative pressure environment on the recharge water at the bottom of the water outlet pipe 4 is not greater than the gravity of the recharge water at the bottom of the water outlet pipe 4. The recharge water to be treated is continuously injected into the sealing cylinder 1 through the water inlet pipe 2. The gas contained in the recharge water in the sealing cylinder 1 is separated from the recharge water under the action of the negative pressure. The liquid level of the recharge water in the sealing cylinder 1 rises. At the same time, start the ultrasonic emitter 9 to shatter the small bubbles in the recharge water, so that the gas in the small bubbles is separated and enters the upper end of the liquid surface in the sealing cylinder 1. And the suction force of the negative pressure environment on the recharge water at the bottom of the water outlet pipe 4 is less than the gravity of the recharge water at the bottom of the water outlet pipe 4. The treated recharge water is discharged through the opened water outlet pipe 4. And when the sealing cylinder 1 is full of water, when the cylinder 601 is started, the cylinder 601 pushes the short rod 602 downward. When the short rod 602 moves, the short rod 602 moves in the spiral groove opened in the rotating sleeve 603, so that the short rod 602 can squeeze the spiral groove, and thus the rotating sleeve 603 can be rotated. When the rotating sleeve 603 rotates, it drives the stirring rod 604 to rotate. When the stirring rod 604 rotates, it drives the rotating shaft 605 to do a circular motion synchronously. When the rotating shaft 605 does a circular motion, it drives the rotating piece 606 to do a circular motion, so that the rotating piece 606 stirs the water flow. On the contrary, when the cylinder 601 pulls the short rod 602 upward, when the short rod 602 moves upward, the short rod 602 slides inside the rotating sleeve 603. When the short rod 602 slides inside the rotating sleeve 603, it squeezes the rotating sleeve 603 to rotate in the reverse direction. When the rotating sleeve 603 rotates in the reverse direction, it drives the stirring rod 604 to rotate in the reverse direction. When the stirring rod 604 rotates in the reverse direction, it drives the rotating shaft 605 to move synchronously. When the rotating shaft 605 moves, it drives the rotating piece 606 to move, so that the rotating piece 606 stirs the water flow. When the cylinder 601 pushes downward, the connecting rod 607 moves downward. When the connecting rod 607 moves downward, it drives the ring disk 608 to move downward synchronously, so that the ring disk 608 enters into the liquid, so that the impurities floating on the top of the liquid and the liquid enter the ring disk 608 at the same time. On the contrary, when the cylinder 601 pushes upward, the connecting rod 607 moves upward. When the connecting rod 607 moves upward, it drives the ring disk 608 to move upward synchronously. At this time, the filtered heat energy liquid flows out from the filter holes 609, and the impurities are left in the ring disk 608.

[0035] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, a collection and compaction device 7 for concentrating impurities for treatment without affecting the collection of filtered impurities is provided inside the closed cylinder 1, including a horizontal block 701, a sliding rod 702, a rotating sleeve 703, a fixed block 704, an inclined throwing piece 705, a collection box 706, a striking block 707, an L-shaped platform 708 and a compaction piece 709.

When the air cylinder 601 pulls, it drives the sliding rod 702 to move upward. The lower side of the horizontal block 701 is rotatably connected to the upper end of the rotating sleeve 703, and the outer wall of the sliding rod 702 fits with the inner wall of the spiral groove formed in the inner wall of the rotating sleeve 703. When the sliding rod 702 moves upward, the sliding rod 702 moves in the spiral groove formed in the rotating sleeve 703, so as to be able to squeeze the rotating sleeve 703 to rotate. The outer wall of the rotating sleeve 703 is fixedly connected to the inner end of the fixed block 704. When the rotating sleeve 703 rotates at the lower end of the horizontal block 701, it drives the fixed block 704 to rotate synchronously. The outer end of the fixed block 704 is fixedly connected to the inner side of the inclined throwing piece 705. When the fixed block 704 rotates, it drives the inclined throwing piece 705 to rotate. The inner wall of the closed cylinder 1 is fixedly connected to the outer wall of the collection box 706. The upper end of the annular disk 608 is fixedly connected to the lower end of the striking block 707. When the annular disk 608 moves downward, it drives the striking block 707 to move downward synchronously. The inner wall of the closed cylinder 1 is fixedly connected to the upper end of the compression spring 710, and the lower end of the compression spring 710 is fixedly connected to the upper side of the compaction piece 709. The upper side of the compaction piece 709 is fixedly connected to the lower side of the L-shaped platform 708. When the striking block 707 moves downward, the L-shaped platform 708 moves downward.

[0036] By providing the collection and compaction device 7, when the air cylinder 601 is started, the sliding rod 702 moves in the spiral groove formed in the rotating sleeve 703, so as to be able to squeeze the rotating sleeve 703 to rotate, and through the cooperation of the fixed block 704 and the inclined throwing piece 705, the inclined throwing piece 705 sweeps the impurities in the annular disk 608 into the collection box 706, solving the problem of blockage caused by impurity accumulation in the traditional static filter screen and maintaining high filtration efficiency;

[0037] And when the annular disk 608 moves, the striking block 707 moves away from the L-shaped platform 708, enabling the compression spring 710 and the compaction piece 709 to cooperate, so that the compaction piece 709 compresses the impurities in the collection box 706, solving the problems of insufficient compression and insufficient storage capacity of the static collection device, improving the single storage capacity, and reducing the frequency of replacing the collection box 706.

[0038] Inside the closed cylinder 1, there is a knocking device 8 that makes the impurities in the collection box 706 more evenly distributed, thereby increasing the loading capacity. The knocking device 8 includes a rotating rod 801, a torsion spring 802, a retaining piece 803, a connecting block 804, an L-shaped piece 805, a striking piece 806, and a return spring 807. The inner wall of the compaction piece 709 is rotatably connected to the outer wall of the rotating rod 801. One end of the torsion spring 802 is fixedly connected to the inner wall of the compaction piece 709, and the other end of the torsion spring 802 is fixedly connected to the outer wall of the retaining piece 803. The inner wall of the retaining piece 803 is fixedly connected to the outer wall of the rotating rod 801. When the compaction piece 709 moves downward, it drives the retaining piece 803 to move synchronously. The outside of the collection box 706 is fixedly connected to the inside of the connecting block 804. The inner wall of the connecting block 804 is rotatably connected to the outer wall of the L-shaped piece 805. When the retaining piece 803 moves downward, it causes the retaining piece 803 to squeeze the L-shaped piece 805 to rotate. The lower end of the L-shaped piece 805 is fixedly connected to the upper side of the striking piece 806. When the L-shaped piece 805 rotates, it drives the striking piece 806 to rise. The outer end of the striking piece 806 is fixedly connected to one end of the return spring 807, and the other end of the return spring 807 is fixedly connected to the inner wall of the closed cylinder 1.

[0039] In the present invention, by setting the knocking device 8, when the compaction piece 709 moves, it drives the retaining piece 803 to move, causing the retaining piece 803 to strike the L-shaped piece 805 to rotate. Through the cooperation of the L-shaped piece 805 and the return spring 807, the striking piece 806 strikes the collection box 706, making the impurities in various states in the collection box 706 more evenly distributed in the collection box 706. This solves the problem that the hardness and volume of the impurities in the collection box 706 are different, resulting in uneven compaction due to the uneven height in the collection box 706, and improves the compaction effect.

[0040] During the operation of this embodiment: When the cylinder 601 pulls, it drives the slide rod 702 to move upward. When the slide rod 702 moves upward, it makes the slide rod 702 slide within the rotating sleeve 703. When the slide rod 702 slides within the rotating sleeve 703, it makes the rotating sleeve 703 rotate in the reverse direction at the lower end of the cross block 701. When the rotating sleeve 703 rotates in the reverse direction at the lower end of the cross block 701, it drives the fixed block 704 to rotate synchronously in the reverse direction. When the fixed block 704 rotates in the reverse direction, it drives the inclined chip 705 to rotate in the reverse direction, causing impurities to be squeezed and accumulated. Conversely, when the cylinder 601 pushes, it drives the slide rod 702 to move downward. When the slide rod 702 moves downward, it makes the slide rod 702 slide within the rotating sleeve 703. When the slide rod 702 slides within the rotating sleeve 703, it makes the rotating sleeve 703 rotate at the lower end of the cross block 701. When the rotating sleeve 703 rotates at the lower end of the cross block 701, it drives the fixed block 704 to rotate synchronously. When the fixed block 704 rotates, it drives the inclined chip 705 to rotate, causing the filtered impurities to be squeezed along the arc of the inclined chip 705 and enter the collection box 706; When the circular ring plate 608 moves upward, it drives the striker 707 to move upward synchronously. When the striker 707 moves upward, it pushes the L-shaped platform 708 to move upward. When the L-shaped platform 708 moves upward, it drives the compaction piece 709 to squeeze the compression spring 710, causing the overall device to reset. Conversely, when the circular ring plate 608 moves downward, it drives the striker 707 to move downward synchronously. When the striker 707 moves downward, the L-shaped platform 708 moves downward, and the compression spring 710 that loses the blockage pushes the compaction piece 709 to fall downward, compacting the slag in the collection box 706.

[0041] When the compaction piece 709 moves upward for reset, it drives the retaining piece 803 to move upward synchronously. When the retaining piece 803 moves upward, the retaining piece 803 touches the L-shaped platform 708. When the retaining piece 803 touches the L-shaped platform 708, the retaining piece 803 rotates downward. When the retaining piece 803 rotates downward until it passes over the L-shaped platform 708, it resets under the action of the torsion spring 802; Conversely, when the compaction piece 709 moves downward, it drives the retaining piece 803 to move synchronously. When the retaining piece 803 moves downward, it makes the retaining piece 803 squeeze the L-shaped block 805, and the L-shaped block 805 rotates around the connecting block 804. When the L-shaped block 805 rotates, it drives the striking piece 806 to rise. When the compaction piece 709 drives the retaining piece 803 to pass over the L-shaped block 805, under the action of the return spring 807, the L-shaped block 805 drives the striking piece 806 to quickly reset, causing the L-shaped block 805 to impact the collection box 706, making the distribution of impurities more uniform.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
