Description

Technical Field

[0001] The present invention belongs to the technical field of carbon dioxide capture, and specifically relates to a carbon dioxide capture and release device. Background Art

[0002] Carbon dioxide capture and release facilities, in a broad sense, refer to a combination of technologies and equipment designed to capture carbon dioxide (CO2) from industrial emissions or other sources and subsequently process, store or reuse it.

[0003] The prior art also proposes some solutions: for example, a Chinese patent application with publication number CN118370292A discloses a carbon dioxide capture and release device: comprising a tank body, on which an air inlet and an exhaust port are arranged, and the regional release of carbon dioxide is achieved by cleverly adjusting the contact mode between the heating module and the carbon dioxide adsorbent. On the one hand, it can ensure that the carbon dioxide output fluctuates in an orderly manner within a certain range, thereby improving the stability of the carbon dioxide output; on the other hand, by gradually releasing carbon dioxide in different zones, it can avoid releasing carbon dioxide all at once, thereby extending the duration of carbon dioxide release; at the same time, the structure of the present application is simple, which is conducive to improving the stability and reliability of the entire device while reducing costs.

[0004] Carbon dioxide capture usually involves extracting carbon dioxide from industrial flue gas for storage. The industrial flue gas needs to be passed into a tank first, and then the carbon dioxide in the flue gas is absorbed and captured using suitable chemical reagents. When the existing device passes the flue gas into the tank, the industrial flue gas cannot be evenly diffused in every corner of the tank, but is crowded together. When spraying chemical reagents for capture, the reagents cannot fully contact all the flue gas, resulting in the inability to effectively capture the carbon dioxide in some flue gases, resulting in low capture efficiency and other problems.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 9 As shown, the present invention provides a technical solution: a carbon dioxide capture and release device, comprising a tank body 1, side blocking plates 5 are fixedly connected to both sides of the tank body 1, a smoke inlet 6 is fixedly connected to the inner wall of one of the side blocking plates 5, one end of the smoke inlet 6 is fixedly connected to a spray head 7, the spray head 7 is located inside the tank body 1, an injection assembly for spraying smoke is arranged inside the smoke inlet 6, a spray box 3 is fixedly connected to the top of the tank body 1, a spray assembly is arranged inside the spray box 3, a storage box 2 is fixedly connected to the bottom of the tank body 1, a workbench 4 is fixedly connected to the bottom of the storage box 2, two side blocking plates 5 are fixedly installed on the top of the workbench 4, a diffusion assembly is arranged inside the tank body 1, the diffusion assembly is used to diffuse the sprayed smoke inside the tank body 1, a smoke outlet pipe 39 is fixedly connected to the inner wall of the other side blocking plate 5, and an electric valve 40 is arranged on the outer wall of the smoke outlet pipe 39.

[0034] During operation: when the smoke is introduced into the tank body, the industrial smoke cannot be evenly diffused to every corner of the tank body, but is crowded together. Through the embodiment of this scheme, when it is used specifically, the industrial smoke is first introduced into the interior of the smoke inlet 6, and the smoke enters the interior of the tank body 1 from the injection head 7 at one end of the smoke inlet 6. When the interior of the smoke inlet 6 is filled with smoke, the injection assembly is started, and the injection assembly can inject the smoke inside the smoke inlet 6 into the interior of the tank body 1 in the form of a column from the nozzle of the injection head 7, and When the smoke is sprayed into the tank 1, it will hit the diffusion component. The smoke hitting the diffusion component will be quickly diverted and diffused to every corner of the tank 1. This will be repeated many times. After the smoke enters the tank 1, it will be evenly dispersed in every corner of the tank 1. At this time, the absorbent will be sprayed down in the form of small droplets through the spray component. Before falling into the spray box 3, the small droplets will completely flow through the tank 1 and can react with the carbon dioxide in the smoke. Carbon reacts, carbon dioxide can be adsorbed by the absorbent and fall into the interior of the spray box 3 for storage. After spraying, the electric valve 2 40 at the smoke outlet pipe 39 is opened to discharge excess smoke from the smoke outlet pipe 39, thereby completing the entire carbon dioxide capture work. Through the above embodiment, when the smoke is injected into the interior of the tank body 1 in the form of injection and diffusion, the smoke can be evenly dispersed in the interior of the tank body 1, which helps to increase the contact area between the smoke and the spray liquid, thereby improving the carbon dioxide capture efficiency. The spraying method can directly spray the absorbent into the smoke, react chemically with the carbon dioxide in the smoke, and convert it into a solution. The operation is simple and the reaction is rapid. The columnar injection can concentrate the flow energy of the smoke, so that the smoke has a higher speed and impact force when it hits the diffusion component, thereby achieving more efficient diffusion. After the smoke hits the diffusion component, it is quickly diverted and can be more evenly diffused to every corner of the tank body, avoiding the problem of excessive or low local concentration that may be caused by a shower-type nozzle.

[0035] like Figures 2 to 3 As shown, the injection assembly includes a telescopic cylinder 15, which is fixedly installed on the top of the workbench 4, and the output end of the telescopic cylinder 15 is fixedly connected to the impact rod 14, one end of the smoke inlet 6 is fixedly connected to the blocking plate 11, the impact rod 14 is plugged into the inner wall of the blocking plate 11, and one end of the impact rod 14 is fixedly connected to the piston 12, and the piston 12 is slidably connected to the inner wall of the smoke inlet 6 and adapts to each other.

[0036] During operation: after the industrial smoke enters the interior of the smoke inlet 6, the telescopic cylinder 15 is started, and its output end drives the piston 12 to slide in the interior of the smoke inlet 6 through the impact rod 14. When the piston 12 slides quickly toward the injection head 7, the smoke will be squeezed to be ejected from the nozzle of the injection head 7, and the nozzle of the injection head 7 has a small diameter. When the smoke is squeezed and ejected by the piston 12, it will be ejected from the injection head 7 in a columnar form, and then the telescopic cylinder 15 drives the piston 12 to reset. After resetting, the interior of the smoke inlet 6 is refilled with smoke, waiting for the next smoke ejection.

[0037] like Figure 3 to Figure 4 As shown, the top of the middle part of the smoke inlet 6 is fixedly connected with a smoke inlet pipe 8, the top of the smoke inlet pipe 8 is fixedly connected with a filter bin 9, the inside of the filter bin 9 is provided with an intercepting grid plate 10, the smoke inlet 6 and the smoke inlet pipe 8 are mutually connected with a gas reflux pipe 13, and the outside of the smoke inlet pipe 8 is provided with an electric valve three 41 and an electric valve four 42.

[0038] During operation: industrial smoke is injected from the top of the filter bin 9 and injected into the interior of the smoke inlet 6 through the smoke inlet pipe 8. The smoke can automatically intercept fine impurities in the smoke when passing through the interception grid 10 to prevent the impurities from affecting the capture of carbon dioxide. When the piston 12 slides inside the smoke inlet 6 to eject the smoke from the injection head 7, the electric valve 42 is closed and the electric valve 3 41 is opened. During the squeezing and ejecting process of the piston 12, the smoke can gradually enter the smoke inlet 6 from the reflux pipe 13. Internally, during the resetting process of the piston 12, the electric valve four 42 is opened and the electric valve three 41 is closed. During the resetting process of the piston 12, the smoke entering the smoke inlet pipe 6 can be squeezed by the piston 12 and refluxed into the entire chamber of the smoke inlet pipe 6 through the reflux pipe 13 and the smoke inlet pipe 8. When the piston 12 is pushed next time, the smoke has filled the inside of the smoke inlet pipe 6 again, making it easier for the piston 12 to squeeze and inject the smoke next time, thereby achieving a cyclic operation in which the smoke can be squeezed out and filled every time the piston 12 moves repeatedly inside the smoke inlet pipe 6.

[0039] like Figures 5 and 6 As shown, the diffusion assembly includes a diffuser 16, which is located inside the tank body 1, one end of the diffuser 16 corresponds to the nozzle of the injection head 7, a plurality of diffusion grooves 17 are provided on the inner wall of the surface of the diffuser 16, a connecting piece 18 is symmetrically fixedly connected to one side of the diffuser 16, one end of the connecting piece 18 is fixedly connected to an inner slider 19, an inner mounting seat 20 is symmetrically fixedly connected to the inner side surface of the tank body 1, the inner slider 19 is slidably connected to the inner mounting seat 20 and is adapted to each other, a push assembly is provided at one end of the inner slider 19, and the push assembly is used to drive the inner slider 19 to move in the inner wall of the inner mounting seat 20.

[0040] During operation: when the smoke is ejected from the injection head 7 in a columnar form, it will hit one end of the diffuser 16, and after the smoke hits one end of the diffuser 16, it will flow along the path of multiple diffusion grooves 17, and finally diffuse to various corners inside the tank body 1, and when the smoke continues to hit the diffuser 16, the inner slider 19 can also move in the inner wall of the inner mounting seat 20 through the pushing assembly, and the inner slider 19 drives the diffuser 16 to move inside the tank body 1 through the connecting piece 18, so that the smoke can continue to diffuse to various corners inside the tank body 1, and can also diffuse to various areas inside the tank body 1, thereby achieving the effect that the smoke can be evenly diffused to various positions inside the tank body 1.

[0041] like Figures 5 and 6 As shown, the pushing assembly includes two outer mounting seats 22, and the two outer mounting seats 22 are fixedly mounted on the top of the tank body 1. The inner wall of the outer mounting seat 22 is slidably connected with a sliding member 21, and a push rod 23 is fixedly connected to the top side of the sliding member 21. The end of the push rod 23 away from the sliding member 21 is fixedly connected to one side of the inner sliding block 19, and the outer walls of the push rod 23 are respectively plugged into the side blocking plate 5 and the inner wall of the inner mounting seat 20, and the outer wall of the impact rod 14 is fixedly connected with a pushing member 24. A reset spring 25 is arranged on the outside of the push rod 23, and one end of the reset spring 25 is fixedly connected to one side of the sliding member 21, and the other end of the reset spring 25 is fixedly connected to one side of the side blocking plate 5.

[0042] During operation: when the telescopic cylinder 15 is started to make the piston 12 move inside the smoke inlet 6 to squeeze the smoke, the pushing member 24 can push the sliding member 21 to slide inside the outer mounting seat 22, and the sliding member 21 can make the inner slider 19 slide inside the inner mounting seat 20 through the push rod 23 during the sliding process. In this way, when the injection head 7 continuously sprays smoke and hits one end of the diffuser 16 for diffusion, the diffuser 16 can continuously slide inside the tank body 1, so that the smoke is evenly dispersed inside the tank body 1, and when the telescopic cylinder 15 drives the piston 12 to reset, the diffuser 16 can be reset by the reset spring 25. This operation can be achieved every time the smoke is sprayed, and the smoke is evenly dispersed every time.

[0043] like Figures 7 and 8 As shown, the spray assembly includes a liquid storage tank 26, which is fixedly installed on the top of the spray box 3. Both sides of the liquid storage tank 26 are fixedly connected with liquid outlet hoses 27. A diversion pipe 28 is fixedly connected between the other ends of the two liquid outlet hoses 27. The bottom of the diversion pipe 28 is fixedly connected with multiple liquid spray heads 29. Both ends of the diversion pipe 28 are provided with shaking assemblies, which are used to drive the multiple liquid spray heads 29 to swing continuously.

[0044] During operation: after the flue gas is evenly injected into the interior of the tank body 1, the valve on one side of the liquid storage tank 26 is opened, so that the absorbent first flows into the diversion pipe 28 through the liquid outlet hose 27, and then is sprayed out in the form of small droplets through the liquid spray head 29. The small droplets will contact the flue gas during the falling process and react with the carbon dioxide in the flue gas. The carbon dioxide can be adsorbed by the absorbent and fall into the interior of the spray box 3 for storage. During the spraying process, the shaking component is started to make multiple liquid spray heads 29 swing continuously. The swinging of the liquid spray head 29 can expand the spraying range, so that the absorbent can fully absorb the carbon dioxide, thereby improving the carbon dioxide separation, capture and recovery efficiency.

[0045] like Figures 8 to 9 As shown, the shaking assembly includes a telescopic cylinder 2 31, which is fixedly installed on the side of the tank body 1, and the output end of the telescopic cylinder 2 31 is fixedly connected to a push plate 32, and one side of the push plate 32 is symmetrically fixedly connected to a rack plate 33, and both ends of the diverter pipe 28 are symmetrically fixedly connected to a fan gear 30, and the teeth of the fan gear 30 are meshed with the teeth of the rack plate 33.

[0046] During operation: when spraying is required, the telescopic cylinder 2 31 is started, and its output end drives the push plate 32 to move back and forth repeatedly. During the movement, the push plate 32 drives the rack plate 33 to move and makes the rack plate 33 mesh with the sector gear 30. During the repeated movement of the rack plate 33 back and forth, the sector gear 30 is continuously rotated in two directions, so that the sector gear 30 continuously rotates forward and reverse, and the rotation angle is the same as the angle between the teeth of the sector gear 30, thereby achieving the effect that the liquid spray head 29 can continuously swing.

[0047] like Figure 1 and Figure 7 As shown, a heating pipe 36 is provided outside the storage box 2 , and the heating pipe 36 is fixedly installed on the top of the tank body 1 .

[0048] During operation: After being captured, carbon dioxide will be stored together with the absorbent inside the spray box 3. When carbon dioxide needs to be released, the solution inside the storage box 2 is heated to a certain temperature through the heating pipe 36. The heated carbon dioxide will be separated from the absorbent and discharged from the top of the storage box 2.

[0049] like Figures 7 and 8 As shown, a liquid return pipe 37 is connected between the top of the storage box 2 and the liquid storage box 26 , and a liquid pump 38 is arranged outside the liquid return pipe 37 .

[0050] During operation: After carbon dioxide is separated from the absorption liquid, the liquid extraction pump 38 is turned on to extract the absorption liquid inside the storage box 2, and the absorption liquid flows back to the inside of the liquid storage box 26 through the liquid reflux pipe 37. The absorption liquid is heated to separate carbon dioxide and can be reused after cooling. By using the absorption liquid sequentially, resources are saved and costs are reduced.

[0051] like Figures 7 and 8 As shown, a release pipe 34 is symmetrically fixedly connected to the top of the spray box 3, and an electric valve 35 is arranged outside the release pipe 34.

[0052] During operation: during the capturing process, the electric valve 1 35 blocks the release pipe 34, so that the smoke cannot flow out from the release pipe 34; during the releasing process, the electric valve 2 40 is controlled to block the smoke outlet pipe 39. After the carbon dioxide is released as gas, the electric valve 1 35 is controlled to open the air outlet of the release pipe 34, so that the carbon dioxide can be discharged and released from the release pipe 34.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
