Description

Technical Field

[0001] This invention belongs to the field of carbon dioxide capture technology, specifically relating to an orbital adsorption system and regeneration process for removing carbon dioxide from the air. Background Technology

[0002] Direct air capture (DAC) technology, as an emerging means of negative carbon emissions, is one of the key technologies to achieve the goals of "carbon peaking" and "carbon neutrality". It can not only capture carbon from decentralized emission sources (such as vehicles) that are difficult to treat centrally, but also directly reduce the concentration of carbon dioxide in the atmosphere. By utilizing or storing the captured carbon resources, it can create a negative carbon effect, which has profound significance for addressing climate change.

[0003] However, most current mainstream DAC technologies employ a fixed-bed process, which uses high-powered fans to force air into a fixed tower filled with adsorbent. This process has two significant bottlenecks: First, the fans consume a large amount of energy to overcome the resistance of the adsorbent bed, which has become a major component of the operating cost of DAC systems. Especially when relying on off-grid renewable energy, the high cost of supporting energy storage greatly restricts its large-scale application. Second, the operation of the fans generates continuous noise of up to 85 decibels or more. The noise pollution is even more severe when multiple devices work together, which not only increases the cost of noise reduction but also limits its deployment in noise-sensitive areas such as residential areas.

[0004] In summary, the inherent drawbacks of existing fixed-bed DAC technology in terms of energy consumption and noise severely hinder its large-scale adoption and environmental friendliness. Therefore, the industry urgently needs to develop an innovative process and system that can fundamentally eliminate reliance on forced draft, achieving efficient capture and regeneration of carbon dioxide from the air in a more energy-efficient and quieter manner.

[0022] Please see the appendix Figures 1 to 4As shown, this is the first embodiment of the present invention. This embodiment provides a track-type adsorption system for removing carbon dioxide from the air, including a desorption cabinet 10. The desorption cabinet 10 has a desorption chamber 11 and a clearance chamber 12 inside, with the desorption chamber 11 located above the clearance chamber 12. First openings are provided on both sides of the desorption chamber 11, and second openings are provided on both sides of the clearance chamber 12. A ring track 13 is installed at the lower end of the interior of the desorption cabinet 10, and the ring track 13 penetrates the interior of the clearance chamber 12. The system also includes: Multiple flow adsorption components 20 are assembled on the upper end of the annular track 13. Each flow adsorption component 20 includes a track transport vehicle 21, multiple support rods 22, and multiple trays 23. The track transport vehicle 21 is movably connected to the upper end of the annular track 13. The multiple support rods 22 are detachably inserted into the four corners of the top of the track transport vehicle 21. The multiple trays 23 are fixed between the multiple support rods 22 from the top to the bottom. The inside of the trays 23 carries the adsorption medium. The multiple support rods 22, trays 23, and adsorption medium located inside the same flow adsorption component 20 constitute an adsorption unit. Two hatch assemblies 30 are respectively assembled on both sides of the analytical cavity 11, and the two hatch assemblies 30 are adapted to the two first compartment openings one by one. The hatch assemblies 30 are configured to block the first compartment openings, so that a sealed space is formed inside the analytical cavity 11. The transfer assembly 40 is assembled at the lower end inside the analytical cavity 11; The first robotic arm unit 50 is disposed on one side of the analytical cavity 11 and is configured to perform a feeding operation on the adsorption unit at the top of the rail transport vehicle 21 located within its working range. The second robotic arm unit 51 is located on the other side of the analytical chamber 11. The second robotic arm unit 51 is configured to perform unloading operations on the adsorption unit located inside the analytical chamber 11. The first robotic arm unit 50 and the first bin opening, as well as the second robotic arm unit 51 and the first bin opening, are all adapted to each other. A steam generating unit 60 is located outside the desorption cabinet 10, and the output end of the steam generating unit 60 is connected to the desorption chamber 11 through a pipeline. The steam generating unit 60 is configured to input high-temperature steam into the desorption chamber 11. Vacuum pump unit 70 is located outside the desorption cabinet 10, and the input end of vacuum pump unit 70 is connected to desorption chamber 11 through a pipeline. Vacuum pump unit 70 is configured to extract gas from inside desorption chamber 11. The condenser unit 80 is located outside the desorption cabinet 10, and the input end of the condenser unit 80 is connected to the desorption chamber 11 through a pipeline. The condenser unit 80 is configured to extract the gas inside the desorption chamber 11 and cool the extracted gas. A compression storage unit 90 is disposed outside the analytical cabinet 10, and the input end of the compression storage unit 90 and the output end of the condenser unit 80 are also connected by a pipeline. The compression storage unit 90 is configured to compress and store the gas at the output end of the condenser unit 80. Among them, the rail transport vehicle 21 can drive the adsorption unit to move cyclically along the circular track 13 and separate and adsorb carbon dioxide in the air.

[0023] It should be noted that a control terminal is also used in conjunction with the device. The control terminal can control the opening and closing of various electrical components inside the device and the overall operation of the device.

[0024] Furthermore, an online carbon dioxide analyzer is installed between the condenser unit 80 and the compression and storage unit 90. The online carbon dioxide analyzer is configured to detect the gas output from the condenser unit 80 and analyze the carbon dioxide content.

[0025] Here, the rail transport vehicle 21, the first robotic arm unit 50, the second robotic arm unit 51, the steam generating unit 60, the vacuum pump unit 70, the condenser unit 80, and the compression storage unit 90 are all existing mature applications. Their specific internal structures and working principles can be referred to existing technologies, and will not be elaborated further here.

[0026] In this embodiment, when removing carbon dioxide from the air, since the adsorption unit is exposed to the air, the carbon dioxide in the air is adsorbed by the adsorption medium carried inside the tray 23 until the adsorption medium reaches adsorption saturation. Then, the rail transport vehicle 21 is activated, which moves the adsorption unit located on its upper end towards the first robotic arm unit 50 until the rail transport vehicle 21 moves into the working range of the first robotic arm unit 50. Then, the hatch assembly 30 is activated, which opens the desorption chamber 11. Finally, the first robotic arm unit 50 is activated, and the adsorption unit located on the rail transport vehicle 21... The adsorption unit at the end moves into the desorption chamber 11 and is placed on the upper end of the transfer assembly 40. After the first robotic arm unit 50 is reset, the rail transport vehicle 21 is restarted until it moves to the second robotic arm unit 51. The door assembly 30 is reversed, causing the desorption chamber 11 to become closed. The vacuum pump unit 70 is started to evacuate the closed desorption chamber 11. The steam generator unit 60 is started to input high-temperature water vapor into the desorption chamber 11, creating a high-temperature, low-pressure closed space inside the desorption chamber 11. This causes the saturated adsorption medium inside the desorption chamber 11 to release the carbon dioxide it has absorbed, thus achieving adsorption. For medium regeneration, the condenser unit 80 is activated. The condenser unit 80 extracts carbon dioxide from the desorption chamber 11. After entering the condenser unit 80, the carbon dioxide is cooled and its moisture is separated, increasing the dryness of the carbon dioxide gas. The compression and storage unit 90 is then activated to compress and store the carbon dioxide output from the condenser unit 80. After the carbon dioxide extraction from the desorption chamber 11 is complete (the carbon dioxide content in the gas output from the condenser unit 80 is monitored by an online carbon dioxide analyzer), the transfer assembly 40 is activated. The transfer assembly 40 then moves the adsorption unit towards the direction of the second robotic arm unit 51. The cylinder 33 is activated, causing the desorption chamber 11 to change from a closed to an open state. The second robotic arm unit 51 is then activated, and the adsorption unit located at the upper end of the transfer component 40 is unloaded and placed on the upper end of the rail transport vehicle 21. The rail transport vehicle 21 then drives the regenerated adsorption unit to move along the circular track 13 again. In the above scheme, the adsorption medium is moved along the circular track 13 by the rail transport vehicle 21, so that the adsorption medium directly captures carbon dioxide in the air under natural conditions. The fluidized bed adsorption process eliminates the need for a fan during adsorption, which solves the problems of high noise and high energy consumption compared to the fixed bed process.

[0027] Here, the height of the clearance cavity 12 and the second compartment opening are sufficient to ensure that the unloaded rail transport vehicle 21 can pass smoothly.

[0028] Furthermore, the carbon dioxide content in the gas output from the condenser unit 80 is monitored by an online carbon dioxide analyzer. When the carbon dioxide content in the gas output from the condenser unit 80 is 0, it can be determined that the carbon dioxide inside the analysis chamber 11 has been completely extracted.

[0029] It should be noted that the adsorption medium can absorb carbon dioxide from the air. The adsorption medium can be any one of the following substances: solid amine-functionalized adsorbent, alkali metal carbonate-based adsorbent, or other solid absorbents that can absorb carbon dioxide. In this embodiment, the adsorption medium is preferably a solid amine-functionalized adsorbent.

[0030] In one specific embodiment, the circular track 13 has an integrated power supply system that can continuously supply power to the track transport vehicle 21.

[0031] In a preferred embodiment, the sidewall of the support rod 22 is uniformly provided with a plurality of vent holes, the diameter of which is denoted as D1 and the particle diameter of the adsorption medium is denoted as D2, where D1 < D2.

[0032] Furthermore, in this embodiment, the thickness of the support rod 22 in the vertical plane is 2cm to avoid the accumulation of adsorption medium inside the support rod 22, which would prevent the adsorption medium in the middle from effectively absorbing carbon dioxide in the air.

[0033] In this embodiment, the arrangement of the vent holes can increase the contact area between the adsorption medium and the air, thereby improving the carbon dioxide absorption effect. At the same time, the setting of D1 being smaller than D2 can prevent the adsorption medium from leaking out of the vent holes.

[0034] Secondly, please refer to the following as well. Figure 5 and Figure 6 The door assembly 30 includes a base plate 31, a door frame 32, a cylinder 33, and a sealing door 34. The base plate 31 and the door frame 32 are both fixed to one side of the analytical cabinet 10. The base plate 31 is located at the upper end of the door frame 32, and the door frame 32 is located inside the first compartment opening. A guide groove 35 is provided inside the door frame 32, and the guide groove 35 is located outside the analytical cabinet 10. The cylinder 33 is fixed to the side of the base plate 31 away from the analytical cabinet 10. The sealing door 34 is fixed to the output end of the cylinder 33, and the sealing door 34 and the door frame 32 are slidably connected through the guide groove 35. The cylinder 33 is configured to drive the sealing door 34 to move and cause the analytical chamber 11 to change between a closed state and an open state.

[0035] Furthermore, a retaining plate is fixed to the output end of the cylinder 33, and the retaining plate and the sealing door 34 are fixedly connected by screws. The cylinder 33 and the sealing door 34 are fixedly connected by the retaining plate.

[0036] It should be noted that an air pump assembly is used in conjunction with the cylinder 33. The air pump assembly can input or extract gas into the cylinder 33. When the air pump assembly inputs gas into the cylinder 33, the output end of the cylinder 33 extends, causing the analytical chamber 11 to change to a closed state. When the air pump assembly extracts gas from the cylinder 33, the output end of the cylinder 33 retracts, causing the analytical chamber 11 to change to an open state.

[0037] In this embodiment, when it is necessary to load or unload the adsorption unit, the desorption chamber 11 changes from a closed state to an open state. The cylinder 33 is activated, causing the output end of the cylinder 33 to retract. Through the fixed connection between the cylinder 33 and the sealing door 34, the cylinder 33 drives the sealing door 34 to slide along the guide groove 35. When the sealing door 34 no longer blocks the first compartment opening, the desorption chamber 11 changes from a closed state to an open state. The adsorption unit can then be loaded or unloaded by the first robotic arm unit 50 or the second robotic arm unit 51.

[0038] In a preferred embodiment, a plurality of sealing rings are fitted between the sealing door 34 and the door frame 32.

[0039] In this embodiment, the sealing ring can improve the sealing performance of the closed parsing chamber 11 and prevent gas outside the parsing cabinet 10 from entering the parsing chamber 11.

[0040] Please refer to it again. Figure 7 The transfer assembly 40 includes multiple driven rollers 41, a driving roller 42, a conveyor belt 43, a drive motor 44, and multiple support rollers 45. The driven rollers 41 and the driving roller 42 are rotatably connected to both sides inside the analytical chamber 11, respectively. The conveyor belt 43 is mounted on the outside of the driven rollers 41 and the driving roller 42. The drive motor 44 is fixed to the lower end inside the analytical chamber 11, and the output end of the drive motor 44 is fixedly connected to the driving roller 42. The multiple support rollers 45 are all rotatably connected to the inside of the analytical chamber 11 and located inside the conveyor belt 43.

[0041] Furthermore, multiple flange seats 46 are fixed at both ends inside the analytical chamber 11, and the driven roller 41 and analytical cabinet 10, the driving roller 42 and analytical cabinet 10, and the support roller 45 and analytical cabinet 10 are all rotatably connected through the flange seats 46.

[0042] It should be noted that the drive motor 44 is a vacuum motor (i.e., a motor that can operate stably in a vacuum environment).

[0043] In this embodiment, when regenerating the adsorption unit through the desorption chamber 11, the cylinder 33 is activated, changing the desorption chamber 11 from a closed state to an open state. The first robotic arm unit 50 is then activated to load the adsorption unit and place it on the surface of the conveyor belt 43. After the first robotic arm unit 50 resets, the cylinder 33 is reversed, changing the desorption chamber 11 from an open state to a closed state. The vacuum pump unit 70, the steam generating unit 60, the condenser unit 80, and the compression and storage unit 90 are then activated sequentially. Through the cooperation of the steam generating unit 60, the vacuum pump unit 70, the condenser unit 80, and the compression and storage unit 90, the adsorption medium is regenerated. The drive motor 44 is started, which drives the active roller 42 to rotate. The active roller 42 drives the conveyor belt 43 to move along the outside of the driven roller 41 and the active roller 42. The conveyor belt 43 drives the adsorption unit located at its upper end to move towards the second robotic arm unit 51. The cylinder 33 is started again, so that the desorption chamber 11 changes to the open state. The second robotic arm unit 51 is started, and the adsorption unit located at the upper end of the conveyor belt 43 is unloaded and placed on the upper end of the rail transport vehicle 21. The rail transport vehicle 21 drives the adsorption unit to move again to capture carbon dioxide in the air. Example

[0044] This embodiment provides a carbon dioxide regeneration process applicable to any of the orbital adsorption systems for removing carbon dioxide from the air in Embodiment 1, comprising the following steps: St1: Start the rail transport vehicle 21, and use the rail transport vehicle 21 to drive the adsorption unit to move along the circular track 13 towards the direction of the first robotic arm unit 50 to adsorb carbon dioxide in the air until the adsorption medium reaches saturation. St2: Start cylinder 33 to open the analysis chamber 11, start the first robotic arm unit 50, and transport the adsorption unit closest to the first compartment opening within its working range to the upper end of the conveyor belt 43. Reverse cylinder 33 to close the analysis chamber 11, and start the rail transport vehicle 21 to move to the second robotic arm unit 51. St3: Start the vacuum pump unit 70 to evacuate the closed analytical chamber 11 until the analytical chamber 11 reaches a vacuum state. St4: Start the steam generating unit 60 and input water vapor into the desorption chamber 11 until the temperature inside the desorption chamber 11 reaches 100°C, so that a high temperature and low pressure space is formed inside the desorption chamber 11, causing the adsorption medium to release the carbon dioxide it has absorbed. St5: Start the condenser unit 80 and the compression and storage unit 90. The condenser unit 80 extracts carbon dioxide from the desorption chamber 11 and cools the carbon dioxide flowing through it and separates the water in it. The compression and storage unit 90 compresses and stores the carbon dioxide flowing through the condenser unit 80. St6: Start the drive motor 44 to move the adsorption unit on the surface of the conveyor belt 43 toward the direction of the second robotic arm unit 51, start the cylinder 33 to open the analytical chamber 11, start the second robotic arm unit 51 to unload the adsorption unit on the surface of the conveyor belt 43 and assemble it onto the upper end of the rail transport vehicle 21.

[0045] It should be noted that in this embodiment, in St3, when the vacuum pump unit 70 evacuates the desorption chamber 11, it continues until the pressure inside the desorption chamber 11 is -0.1MPa; in St4, the steam generating unit 60 inputs water vapor with a temperature of 120°C into the desorption chamber 11. Of course, this is only one implementation method and does not constitute a specific limitation.

[0046] Furthermore, in this embodiment, the saturation state of the adsorption medium is determined based on the duration of exposure of the adsorption medium to air. Since the adsorption medium has different materials, its absorption efficiency for carbon dioxide also varies. The exposure time is adjusted according to the specific material of the adsorption medium, and no further limitation is made here.

[0047] The working principle of this invention is as follows: When removing carbon dioxide from the air, the adsorption unit is moved along the circular track 13 by the rail transport vehicle 21. Since the adsorption unit is exposed to the air, the carbon dioxide in the air is adsorbed by the adsorption medium carried inside the tray 23 until the adsorption medium reaches adsorption saturation. The rail transport vehicle 21 is then activated, moving the adsorption unit located at its upper end towards the first robotic arm unit 50. The cylinder 33 is activated, causing the desorption chamber 11 to open. The first robotic arm unit 50 moves the adsorption unit located at the upper end of the rail transport vehicle 21 into the desorption chamber 11 and places it on the upper end of the conveyor belt 43. After the first robotic arm unit 50 is reset, the rail transport vehicle 21 is activated again until it moves to the second robotic arm unit 51. The cylinder 33 is reversed, causing the desorption chamber 11 to close. The vacuum pump unit 70 is activated to evacuate the closed desorption chamber 11. The steam generator unit 60 is activated to generate steam for the desorption chamber. High-temperature water vapor is introduced into the chamber 11, creating a high-temperature, low-pressure closed space inside the chamber 11 to regenerate the adsorption medium. The condenser unit 80 is activated to extract carbon dioxide from the chamber 11. After entering the condenser unit 80, the carbon dioxide is cooled and its moisture is separated. The compression and storage unit 90 is activated to compress and store the carbon dioxide at the output of the condenser unit 80. After the carbon dioxide in the chamber 11 is completely extracted, the drive motor 44 is activated to move the adsorption unit at the top of the conveyor belt 43 toward the second robotic arm unit 51. The cylinder 33 is activated to change the chamber 11 from closed to open. The second robotic arm unit 51 is activated to unload the adsorption unit located at the top of the transfer component 40 and place it on the upper end of the rail transport vehicle 21. The rail transport vehicle 21 then drives the regenerated adsorption unit to move again along the circular track 13.

[0048] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
