Description

Technical Field

[0001] The invention relates to the technical field of low-carbon and clean energy, and in particular to a carbon dioxide accumulator. Background Art

[0002] Since the Industrial Revolution, humans have produced a large amount of carbon dioxide in their production activities, which has been emitted into the atmosphere, causing global warming and having adverse effects on the global natural ecosystem. Carbon capture, utilization and storage will become the key to the successful transition to clean energy.

[0003] A carbon dioxide accumulator is needed for storing carbon dioxide energy. For example, a Chinese patent with announcement number CN210426218U provides a carbon dioxide storage device for storing geothermal energy, including a shell, a bracket is arranged at the bottom end of the shell, and a partition is arranged at the lower part of the inner cavity of the shell. The partition divides the inner cavity of the shell into two upper and lower sealed cavities, and a rotating shaft is arranged in the middle of the partition for rotation. This patent can directly use carbon dioxide as the working medium to absorb and store high-temperature thermal energy of geothermal water wells or hot water in the shell. The carbon dioxide stored in the heat exchanger is converted into high-energy-density high-pressure hot supercritical carbon dioxide fluid, which can be supplied to the supercritical carbon dioxide power generation system for power generation. The impeller, stirring blades, rotating shaft and other mechanisms can disturb the geothermal water to make the thermal energy conversion more sufficient. This patent has a simple structure, occupies a small area, does not affect the stable operation of the ecological environment, has low self-energy consumption, low investment, low operating cost, high energy storage efficiency and safe application.

[0004] Based on the above search and prior art, it is found that: the volume of the heat exchanger is constant. In order to increase the heat exchange time, the heat exchange tubes in the heat exchanger are made into a spiral shape or multiple direct current heat exchange tubes are set. The purpose is to increase the heat exchange area to increase the heat exchange efficiency. If the temperature of the water source for heat exchange is low, the residence time of the water source in the heat exchanger remains unchanged. At this time, the carbon dioxide fluid in the heat exchange tube will absorb heat and become saturated in advance. At this time, the heat exchange water source will dissipate heat to the outside, thereby absorbing the heat of the carbon dioxide fluid after absorbing heat and becoming saturated, thereby reducing the heat exchange efficiency. If the flow rate of the heat exchange water source is increased, the power consumption of the external water pump will increase, and the energy consumption of the entire device will increase.

[0018] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides a carbon dioxide accumulator through improvement. The technical solution of the present invention is: like Figures 1 to 9 As shown, an embodiment of the present invention provides a carbon dioxide accumulator, including a heat exchange tube 2, wherein a plurality of baffles 17 are arranged inside the heat exchange tube 2, and a notch 24 is opened on the outer side of the baffle 17, and the notches 24 of each two adjacent baffles 17 are in opposite positions; An adjusting assembly 14 for adjusting the distance between each baffle 17 is provided inside the heat exchange tube 2; The adjustment assembly 14 includes a plurality of movable plates 19, a scissor-type connecting rod 18, a screw rod 21 and a nut sleeve 22. One side of the heat exchange tube 2 protrudes outward to form a cavity. A guide structure for enabling the movable plate 19 to move linearly is arranged inside the cavity. The plurality of movable plates 19 are fixed one-to-one with the plurality of baffle plates 17. Rotation holes are provided at both ends of the cavity. The two ends of the screw rod 21 are respectively rotatably mounted in the rotation holes. The nut sleeve 22 is adapted to the screw rod 21 and is mounted on the screw rod 21. The movable plate 19 on one end is fixed to the inner wall of one end of the cavity. The movable plate 19 on the other end is fixed to the nut sleeve 22. The plurality of intermediate rotating shafts on the scissor-type connecting rod 18 are respectively rotatably mounted on the plurality of movable plates 19 (the result is as shown in FIG. 1 ). Figure 5 As shown), a driving assembly for rotating the screw rod 21 is installed on the outer side of the heat exchange cylinder 2; It can be seen from the above connection relationship that the driving assembly rotates the screw rod 21, and the screw rod 21 drives the movable plate 19 on one end to move through the screw nut 22. At this time, the scissor-type connecting rod 18 is extended and retracted, so that the spacing between each movable plate 19 is changed by an equal distance. It can be seen that the notches 24 of two adjacent spoilers 17 are in opposite positions. Figure 4 It can be seen that the notch of one baffle 17 is at the top, and the notch of the adjacent baffle 17 is at the bottom, and the hot water source flows in a continuous S shape in the heat exchange tube 2. The regulating component 14 adjusts the distance between the two adjacent baffles 17 in the heat exchange tube 2, thereby controlling the flow path of the hot water source, thereby adjusting the flow time of the hot water source in the heat exchange tube 2. Therefore, without changing the power of the external water pump, the flow time of the hot water source in the heat exchange tube 2 is changed, energy consumption is reduced, and at the same time, low-temperature water is prevented from staying in the heat exchange tube 2 for too long.

[0020] Specifically, combined with Figure 2 and attached Figure 3 As shown, it also includes a bracket 1, a heat exchange tube 2 is fixed to the bracket 1, and the heat exchange tube 2 is horizontally arranged on the bracket 1, a drainage pipe 6 connected to the top of one end of the heat exchange tube 2 is fixed, and a water inlet pipe 5 connected to the bottom of the other end of the heat exchange tube 2 is fixed; an external hot water source is introduced into the water inlet pipe 5 through an external water pump, and the water source flows into the heat exchange tube 2 through the water inlet pipe 5 and flows out from the drainage pipe 6.

[0021] Specifically, combined with Figure 4 As shown, sealing plates 15 are fixed at both ends of the heat exchange tube 2, and a plurality of fixing holes are opened on the plate surface of the sealing plate 15. A heat exchange tube 16 is fixed to every two fixing holes on the same axis. Round covers 3 are fixed at both ends of the heat exchange tube 2, and a connecting pipe 4 connected to the round cover 3 is fixed on the outer side of the round cover 3. The carbon dioxide fluid flows into the round cover 3 through the connecting pipe 4 at one end, and then is divided into each heat exchange tube 16. The carbon dioxide fluid absorbs the heat of the water source in the heat exchange tube 2, and then flows out from the connecting pipe 4 at the other end.

[0022] Specifically, combined with Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the guide structure includes a plurality of guide rods 20, the two ends of which are respectively fixed on the two ends of the cavity, and each movable plate 19 is slidably mounted on each guide rod 20; the guide structure is arranged so that the movable plate 19 can only move linearly in the cavity.

[0023] Specifically, combined with Figure 4As shown, the drive assembly includes a servo motor 7 and a transmission structure. The shell of the servo motor 7 is fixed to the outer side of the heat exchange tube 2. The transmission structure includes a first synchronous wheel 9, a second synchronous wheel 10 and a synchronous belt 8. The output shaft of the servo motor 7 is coaxially fixed with the first synchronous wheel 9, the second synchronous wheel 10 is coaxially fixed with the screw 21, and the synchronous belt 8 is sleeved on the first synchronous wheel 9 and the second synchronous wheel 10; the servo motor 7 rotates the first synchronous wheel 9 through the output shaft. Since the first synchronous wheel 9 and the second synchronous wheel 10 rotate through the synchronous belt 8, and since the second synchronous wheel 10 is fixed with the screw 21, the output shaft of the servo motor 7 rotates the screw 21 through the transmission structure.

[0024] Specifically, combined with Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the baffle plate 17 has a plurality of through holes on its surface, and the baffle plate 17 is slidably mounted on the heat exchange tube 16 through the through holes; the through holes are provided to enable the baffle plate 17 to move along the heat exchange tube 16 .

[0025] Specifically, combined with Figure 7 , Attachment Figure 8 and attached Fig. 9 As shown, the plate surface of the baffle 17 is provided with a plurality of annular scrapers 23 which are integrated with the baffle 17. The plurality of annular scrapers 23 are coaxially arranged one by one with the plurality of through holes, and the inner annular surface of the annular scraper 23 is in contact with the heat exchange tube 16. During the adjustment process of the baffle 17, that is, during the movement of the baffle 17 along the heat exchange tube 16, the annular scrapers 23 on the periphery of the through holes scrape the circumferential outer wall of the heat exchange tube 16 to remove the scale attached to the heat exchange tube 16. The bottom of the heat exchange tube 2 An inclined bucket 11 connected to the heat exchange tube 2 is fixed, and a slag discharge pipe 12 connected to the heat exchange tube 2 is fixed at the lower end of the inclined bucket 11, and a closing valve 13 is installed at the bottom end of the slag discharge pipe 12; when the baffle 17 moves along the heat exchange tube 16, the scale on the outer periphery of the heat exchange tube 16 is scraped off by the annular scraper 23. Since the inflowing water flows in a continuous S shape at each baffle 17, the scale is easy to settle and accumulate at the bottom of the heat exchange tube 2, and is pushed into the inclined bucket 11 by the baffle 17 for centralized collection.

[0026] Working principle: The external hot water source is introduced into the water inlet pipe 5 through an external water pump, and the water source flows into the heat exchange cylinder 2 through the water inlet pipe 5 and flows out from the drain pipe 6; The carbon dioxide fluid flows into the round cover 3 through the connecting pipe 4 at one end, and then flows into each heat exchange tube 16. The carbon dioxide fluid absorbs the heat of the water source in the heat exchange tube 2, and then flows out from the connecting pipe 4 at the other end; The servo motor 7 rotates the first synchronous wheel 9 through the output shaft. Since the first synchronous wheel 9 and the second synchronous wheel 10 rotate through the synchronous belt 8, and since the second synchronous wheel 10 is fixed to the screw rod 21, the output shaft of the servo motor 7 rotates the screw rod 21 through the transmission structure. The screw rod 21 drives the movable plate 19 on one end to move through the screw nut sleeve 22. At this time, the scissor-type connecting rod 18 is extended and retracted, so that the spacing between each movable plate 19 is changed by equal distance. It can be seen that the notches 24 of the two adjacent baffles 17 are in opposite positions, and the hot water source flows in the heat exchange tube 2 in a continuous S shape. The adjustment component 14 adjusts the spacing between the two adjacent baffles 17 in the heat exchange tube 2, thereby controlling the flow path of the hot water source, thereby adjusting the flow time of the hot water source in the heat exchange tube 2. Therefore, without changing the power of the external water pump, the flow time of the hot water source in the heat exchange tube 2 is changed, energy consumption is reduced, and the low-temperature water is prevented from staying in the heat exchange tube 2 for too long. During the adjustment process of the baffle plate 17, that is, during the movement of the baffle plate 17 along the heat exchange tube 16, the annular scraper 23 on the periphery of the through hole scrapes the circumferential outer wall of the heat exchange tube 16 to remove the scale attached to the heat exchange tube 16; As the baffle 17 moves along the heat exchange tube 16, scale on the outer periphery of the heat exchange tube 16 is scraped off by the annular scraper 23. Since the inflowing water flows in a continuous S-shape at each baffle 17, scale is easily precipitated and accumulated at the bottom of the heat exchange tube 2, and is pushed into the inclined bucket 11 by the baffle 17 for centralized collection.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
