Description

Technical Field

[0001] This application relates to the field of carbon capture technology, specifically to a carbon dioxide capture system. Background Technology

[0002] Air carbon capture systems are technologies that directly separate and collect carbon dioxide from ambient air using chemical or physical methods. Their core processes include two key stages: adsorption and desorption. In the adsorption stage, the system selectively captures carbon dioxide molecules from the air using an alkaline solution or solid adsorbent. In the desorption stage, a vacuum or inert gas environment is used to break the binding force between the adsorbent and carbon dioxide, causing it to be released and collected.

[0003] However, existing conventional air carbon capture systems have the following drawbacks when applied to the consumer market: Current air carbon capture systems primarily employ vacuum desorption or inert gas-protected desorption. While these methods effectively capture carbon dioxide from the air, the systems using these processes are complex, have large equipment structures, and impose stringent requirements on supporting equipment, pressure resistance, and sealing performance. This makes them unsuitable for carbon reduction scenarios in residential buildings, especially for everyday consumer applications involving carbon dioxide removal. Furthermore, existing air carbon capture systems have relatively high desorption temperatures, posing certain safety hazards when used in consumer scenarios. Utility Model Content

[0046] Various embodiments of this application will be described more fully below. This application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this application to the specific embodiments disclosed herein, but rather this application should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this application.

[0047] In the following, the terms “comprising” or “may include” as used in the various embodiments of this application indicate the presence of the disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. Furthermore, as used in the various embodiments of this application, the terms “comprising,” “having,” and their cognates are intended only to indicate a particular feature, number, step, operation, element, component, or combination of the foregoing, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing, or the possibility of adding one or more combinations of features, numbers, steps, operations, elements, components, or combinations of the foregoing.

[0048] In various embodiments of this application, the expression "or" or "at least one of A and / or B" includes any combination or all combinations of the words listed simultaneously. For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.

[0049] The terms used in the various embodiments of this application (such as "first," "second," etc.) may modify various constituent elements in the various embodiments, but do not limit the corresponding constituent elements. For example, the above terms do not limit the order and / or importance of the elements. The above terms are only used for the purpose of distinguishing one element from other elements. For example, a first user device and a second user device refer to different user devices, although both are user devices. For example, without departing from the scope of the various embodiments of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0050] like Figure 1-10 As shown, this application provides a carbon dioxide capture system, comprising:

[0051] The housing 1 and the air intake device 2, air exhaust device 3 and release device 4 provided on the housing 1 are all used to realize the gas flow between the inside and outside of the housing 1.

[0052] Carbon capture device 5, located inside housing 1, is used to receive gas input from air intake device 2 and adsorb carbon dioxide;

[0053] The air supply device 7 is connected to the carbon capture device 5 and the exhaust device 3, and is used to discharge the gas after adsorbing carbon dioxide to the outside.

[0054] Gas heating device 6, located inside housing 1, is used to heat the gas inside housing 1; air supply device 7 is also connected to carbon capture device 5 and release device 4, used to transport the gas heated by gas heating device 6 to carbon capture device 5, so that carbon capture device 5 is heated to release carbon dioxide and transport it to a designated space location.

[0055] The opening of the air intake device 2 is adjustable. The air intake device 2 works in conjunction with the release device 4 to regulate the concentration of carbon dioxide emitted by the release device 4.

[0056] This system, through the coordination of the housing 1, air intake device 2, exhaust device 3, carbon capture device 5, gas heating device 6, air supply device 7, and release device 4, achieves a compact structure and simple process. It not only enables direct contact between hot air and the carbon capture device at atmospheric pressure for desorption, making it suitable for consumer-grade devices, but also allows for adjustment of the carbon dioxide release concentration to a designated spatial location according to product application requirements. Furthermore, the integrated design of this system significantly reduces equipment size and space occupation. Compared to existing vacuum desorption or inert gas protected desorption systems, it eliminates the need for complex supporting devices such as large vacuum pumps and inert gas storage tanks, making it suitable for the space constraints of residential and commercial buildings. Furthermore, the gas inside the shell 1 is locally heated by the gas heating device 6, and the hot gas is directionally transported to the carbon capture device 5 by the air supply device 7. This allows the hot air to directly contact the carbon capture device 5 under normal pressure to achieve carbon dioxide desorption, avoiding the high energy consumption problem of traditional heating and regeneration processes. At the same time, the adjustable opening of the air intake device 2 can dynamically adjust the amount of air entering the system according to actual needs. Through the linkage between the air intake device 2 and the release device 4, the amount of gas entering the system and the concentration of carbon dioxide discharged can be adjusted in real time. This allows the gas containing the adjusted carbon dioxide concentration to be sent to the equipment system or place where carbon dioxide is needed for secondary utilization. For example, according to actual needs, desorbed gas with a carbon dioxide concentration of 0.1% to 10% can be produced, which can be used to trap mosquitoes, increase the yield of greenhouse vegetables, adjust the carbon dioxide concentration in closed environments such as cold storage, refrigerators, and cellars, and reduce the indoor carbon dioxide concentration in indoor spaces, underground buildings, and other living environments, thus expanding the uses of carbon dioxide.

[0057] Specifically, the carbon dioxide capture system has an adsorption mode and a desorption mode. In the adsorption mode, the air intake device 2, the exhaust device 3, the carbon capture device 5, and the air supply device 7 work together to reduce the indoor carbon dioxide concentration in indoor spaces, underground buildings, and other residential environments. In the desorption mode, the air intake device 2, the release device 4, the gas heating device 6, and the air supply device 7 work together, and the opening degree of the air intake device 2 is adjustable. The carbon dioxide capture system is used to adjust the concentration of carbon dioxide discharged to the outside environment according to different application scenarios. The carbon dioxide concentration released by the carbon dioxide capture system is between 0.1% and 10% (volume fraction) to attract mosquitoes, increase production in greenhouse vegetable sheds, or regulate the carbon dioxide concentration in enclosed environments.

[0058] like Figure 1-9 As shown, the air outlet 201 of the air inlet device and the air outlet 601 of the gas heating device both face the carbon capture device 5. Both the air outlet 201 of the air inlet device and the air outlet 601 of the gas heating device are equipped with a flow equalization structure 8 for uniform gas diffusion. This application utilizes the design of the flow equalization structure 8 to make the airflow enter the carbon capture module more uniformly, thereby increasing the efficiency of carbon dioxide capture and removal.

[0059] Specifically, the outlet 201 of the inlet device faces the carbon capture device 5 and is equipped with a flow equalization structure 8 for uniformly diffusing the gas, ensuring that the input gas uniformly covers the surface of the adsorbent material in a laminar flow state. During the adsorption stage, the uniform airflow distribution ensures that carbon dioxide molecules are in full contact with the active sites of the adsorbent, avoiding a decrease in adsorption efficiency caused by excessive local concentration gradients. The outlet 601 of the gas heating device faces the carbon capture device 5 and is equipped with a flow equalization structure 8 for uniformly diffusing the gas, ensuring that the heated gas uniformly covers the surface of the adsorbent material in a laminar flow state. During the desorption stage, uniform heating can simultaneously trigger the desorption of carbon dioxide in various areas of the adsorbent, reducing desorption residues caused by uneven temperature distribution and improving the thoroughness of regeneration of the carbon capture device 5.

[0060] like Figure 2 , 8 As shown, the carbon capture device 5 includes multiple adsorption units 51, which are arranged sequentially and combined to form a labyrinth structure or multiple V-shaped structures.

[0061] In one embodiment, multiple adsorption units 51 are arranged sequentially and combined to form a labyrinth structure, allowing the gas to flow in a meandering manner between the adsorption units 51. This structure significantly improves the diffusion-adsorption probability of carbon dioxide molecules by extending the contact path between the gas and the adsorbent, thereby maximizing the adsorbent loading within a limited space.

[0062] In another embodiment, multiple adsorption units 51 are arranged sequentially and combined with each other to form multiple sets of V-shaped structures. This design maximizes the amount of adsorbent in a limited space, making the system volume smaller than that of traditional flat-plate structures, and more suitable for embedded installation in civil buildings.

[0063] like Figure 10 As shown, each adsorption unit 51 contains multiple adsorption particles 511 for desorbing or adsorbing carbon dioxide, and these particles are randomly distributed within the adsorption unit 51. The randomly distributed adsorption particles 511 within the adsorption unit 51 form a multi-level porous network, causing carbon dioxide molecules to undergo multiple collisions and captures during diffusion, thereby improving the efficiency of carbon dioxide capture and removal.

[0064] The adsorbent particles 511 include solid amine particles, metal-organic frameworks, molecular sieves or other solid adsorbent particles 511. The desorption temperature of these adsorbent particles 511 is low, with a maximum temperature not exceeding 80°C, ensuring safety performance and making them suitable for consumer-grade products.

[0065] like Figure 1-10 As shown, the release device 4 includes a release pipe 41 and a release valve 42. One end of the release pipe 41 is connected to the air supply device 7, and the other end of the release pipe 41 is connected to the outside. The release valve 42 is installed on the release pipe 41 and is used to open or close the release pipe 41.

[0066] A temperature sensor for detecting the temperature inside the housing 1 is provided between the carbon capture device 5 and the release device 4. The carbon dioxide capture system also includes a control device 9, which is used to open the release valve 42 when the temperature detected by the temperature sensor is at a preset temperature value, so that the release pipe 41 connects the carbon capture device 5 and the outside.

[0067] This application uses a temperature sensor to monitor the temperature inside the housing 1 in real time, and uses a control device 9 to automatically open the release valve 42 when the preset desorption temperature is reached, thereby realizing automated control of carbon dioxide emissions and making the carbon dioxide release of the carbon dioxide capture system more intelligent during the desorption stage.

[0068] like Figure 1-10 As shown, the outlet of the release device 4 is equipped with a concentration sensor (not shown in the figure) for detecting the concentration of carbon dioxide in the released gas. The control device 9 is also used to close the release valve 42 when the concentration detected by the concentration sensor is less than the preset concentration value.

[0069] The exhaust device 3 includes an exhaust pipe 31 and an exhaust valve 32. One end of the exhaust pipe 31 is connected to the air supply device 7, and the other end of the exhaust pipe 31 is connected to the outside. The exhaust valve 32 is installed on the exhaust pipe 31 and is used to open or close the exhaust pipe 31.

[0070] The intake device 2 includes an intake pipe 21 and an intake valve 22. One end of the intake pipe 21 is connected to the outside, and the other end faces the carbon capture device 5. The intake valve 22 is installed on the intake pipe 21. The control device 9 is also used to open the exhaust valve 32 and the intake valve 22 when the carbon dioxide capture system captures carbon dioxide in the air, so that the exhaust pipe 31 and the intake pipe 21 are both connected to the carbon capture device 5 and the outside.

[0071] This application provides a concentration sensor at the outlet of the release device 4 for detecting the concentration of carbon dioxide in the released gas. When the concentration detected by the concentration sensor is less than a preset concentration value, the control device 9 closes the release valve 42 and opens the exhaust valve 32 and the intake valve 22 at the same time, so that the exhaust pipe 31 and the intake pipe 21 are connected to the carbon capture device 5 and the outside world, making the emission of the gas after adsorption in the adsorption stage of the carbon dioxide capture system more intelligent.

[0072] like Figure 1-10 As shown, the gas heating device 6 includes a heating unit 61, a return gas pipe 62, and a return gas valve 63. The return gas pipe 62 is connected to the carbon capture device 5 and the heating unit 61, respectively. The return gas valve 63 is located in the return gas pipe and is used to realize the gas flow between the carbon capture device 5 and the heating unit 61. This application, through the connection and positional relationship between the heating unit 61, the return gas pipe 62, the return gas valve 63, and the carbon capture device 5, enables the airflow to circulate through the return gas pipe 62, the heating unit 61, and the carbon capture module under the action of the air supply device 7, thereby realizing the release of carbon dioxide by the carbon capture module upon heating.

[0073] The heating unit 61 includes an electric heater or a waste heat recovery unit. Heating is achieved through the electric heater or waste heat recovery unit, resulting in a breakthrough in both energy efficiency and flexibility.

[0074] Specifically, the carbon dioxide capture system of this application is applied to air conditioning equipment. The heating unit 61 adopts a waste heat recovery device, which can effectively recover the heat generated during the operation of the air conditioning equipment and use this heat to release carbon dioxide in the carbon capture device 5, greatly reducing energy consumption.

[0075] like Figure 1 , 5 As shown, the housing 1 includes a cuboid housing 11 or a cylindrical housing 12. Different housing 1 structural designs can meet the needs of various applications.

[0076] This application designs different internal structures for different shell 1 structural designs, specifically:

[0077] In one embodiment, such as Figure 1-4As shown, the housing 1 includes a cuboid housing 11. Air entering through the intake pipe 21 first passes through a specially designed flow equalization structure 8 before diffusing and uniformly entering the carbon capture device 5. The carbon capture device 5 adopts a labyrinth structure, resulting in a larger overall passage area and a larger air volume under the same wind resistance. Simultaneously, the air supply device 7 uses a centrifugal fan, further increasing the air volume, shortening the carbon capture time, and reducing carbon capture energy consumption. The heating unit 61 can use electric heating or low-temperature waste heat. Furthermore, the heating unit 61 is encapsulated with a sheet metal structure, blocking ineffective heat exchange areas at the edges, ensuring that all air passes evenly through the effective heat exchange area of ​​the electric heating, resulting in more uniform heating and more precise temperature control. The cuboid housing, with its sheet metal structure design, is simpler to assemble and lower in cost compared to a cylindrical structure, making it more suitable for commercial environments where functionality and cost are paramount.

[0078] In another embodiment, such as Figure 5-9 As shown, the housing 1 includes a cylindrical housing 12. Air entering through the intake pipe 21 first diffuses and then passes through a specially designed flow equalization structure 8, uniformly entering the carbon capture device 5. The carbon capture device 5 adopts a multi-group V-shaped structure design, which increases the overall airflow area within the cylindrical housing 12. The air is then extracted by the air supply device 7. The cylindrical housing 12 employs a double-layer structure design. During carbon release operation, the air supply device 7 blows the gas from the return air pipe into the interlayer of the cylindrical housing 12, from where it enters the heating unit 61 for heating, and then circulates. Compared to a cuboid structure, the cylindrical structure has more complex components, more precise assembly, and a more attractive appearance, making it more suitable for home use in environments where functionality and aesthetics are important.

[0079] like Figure 10 As shown, the carbon capture device 5 includes a frame 512 and a screen 513 on its exterior. The screen 513 is disposed on the frame 512 and surrounds the frame 512 to form a cavity for accommodating adsorbed particles 511. This application achieves high air permeability of the screen 513 while ensuring the structural pressure-bearing capacity through the composite structure of the frame 512 and screen 513. Compared to traditional screen cylinder structures, with the same adsorbent filling amount, the gas passage resistance is reduced, resulting in less system pressure loss and thus reducing the energy consumption of the air supply device 7.
