Description

Technical Field

[0001] The present application relates to the technical field of air carbon capture, and in particular to an air carbon capture adsorption device. Background Art

[0002] For a long time, the field of air conditioning and indoor ventilation has adopted the method of "fresh air" (i.e., introducing outdoor air) to solve the problem of indoor carbon dioxide enrichment. However, a large amount of fresh air brings more moisture load and heat load to the room, and the exhaust of indoor low-temperature gas also increases the energy consumption of indoor air conditioning in disguise. Therefore, in recent years, air carbon capture has gradually attracted attention due to its mild operating conditions, high adsorption capacity and fast adsorption rate.

[0003] However, the existing carbon capture devices still have the following defects in the application of air conditioning and indoor ventilation: First, the structure of some existing carbon capture devices is unstable. During the adsorption process, the adsorbed particles or adsorbed substances inside are easily discharged to the outside with the gas; the structure of another part of the carbon capture devices is relatively stable, but there is a large working resistance during the adsorption process, the adsorption effect is not good, and the adsorption efficiency is low; second, during the thermal desorption process of the carbon capture device, the active components on the surface of the adsorbent material are easily volatilized to the gas phase with the water vapor, causing the loss of active components, affecting the adsorption effect, and the service life of the carbon capture device is short, which is not convenient for multiple use. Third, during the heating and desorption process of the existing carbon capture device, hot inert gas or heat exchange tubes are used to directly heat the adsorbent material. The hot inert gas heating method makes the purity of the desorbed gas low and increases the time of secondary gas treatment, while the heat exchange tube heating method has low heating efficiency and large energy loss.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] like Figure 1-8As shown, the present application provides an air carbon capture adsorption device, including a shell 20, a heating component and a plurality of adsorption components 10, the heating component is arranged on the shell 20, the plurality of adsorption components 10 are arranged at intervals inside the shell 20, a gas channel 40 is formed between each adjacent adsorption component 10, the gas channel 40 is connected to the outside, and the plurality of gas channels 40 are independent of each other; the adsorption component 10 includes a heat conductor 3, a support body 2 and an adsorption layer 1, the support body 2 is arranged on the heat conductor 3, the support body 2 has a bonding layer 21 on a side away from the heat conductor 3, the adsorption layer 1 is arranged on the support body 2 through the bonding layer 21, the adsorption layer 1 is used to connect with the gas in the gas channel 40 to adsorb carbon dioxide in the gas; the heating component is connected to the heat conductor 3, and is used to enable the heat conductor 3 to obtain heat and transfer heat to the support body 2 through the heat conductor 3, the adsorption layer 1 is also used to connect with the heat of the support body 2 to release the adsorbed carbon dioxide and water vapor to the gas channel 40, and diffuse the thermally unstable substance 12 of the adsorption layer 1 to combine with the support body 2. The present application fully utilizes the space of the outer shell 20 through the coordination of multiple gas channels 40 and multiple adsorption components 10 to achieve full contact between the external gas and the adsorption component 10, thereby effectively improving the adsorption efficiency and adsorption effect. At the same time, the present application specially designs the adsorption component 10. Through the coordination between the heat conductor 3, the support body 2 and the adsorption layer 1, while improving the stability of the adsorption component 10 structure, it can also increase the mass transfer driving force during adsorption, and reduce the loss of thermally unstable substances 12 in the adsorption layer 1 through the action of the bonding layer 21, thereby improving the service life of the adsorption component 10.

[0055] Specifically, Figure 1 As shown, the adsorption layer 1 of the present application is arranged on the supporting body 2 through the adhesive layer 21, so that the adsorption layer 1 is thinly attached to the supporting body 2, thereby changing the existing fine-grained random pile material into a thin layer with a huge surface area, solving the problem of excessive accumulation resistance of fine-grained materials in the prior art. The purity of the active components in the adsorption layer 1 is slightly different, and some active components are thermally unstable substances 12, which are lost during repeated heating. Therefore, the present application uses secondary molding technology to set an adhesive layer 21 on the side of the supporting body 2 away from the heat conductor 3, so that some active components are in contact with the adhesive layer 21 when heated, effectively controlling the loss of active components; thanks to the secondary distribution of active components, the contact area between the airflow and the active components is increased, which means that the internal diffusion resistance of the airflow is reduced, thereby improving the adsorption efficiency, moving the adsorption penetration point backward, and shortening the time to penetrate to saturation, which is more conducive to engineering applications.

[0056] The projected area of ​​the adsorption layer 1 on the supporting layer accounts for 95%-100% of the surface area of ​​the supporting layer close to the adsorption layer 1.

[0057] like Figure 1-4As shown, a plurality of gas channels 40 are sequentially arranged inside the outer shell 20 along the height direction of the outer shell 20, and each gas channel 40 has at least one connecting end 401 for realizing the gas flow between the gas channel 40 and the outside; the adsorption layer 1 includes a plurality of adsorption particles 11 and / or a plurality of powders, and the plurality of adsorption particles 11 and / or a plurality of powders are arranged on the supporting body 2 through the bonding layer 211; the plurality of adsorption particles 11 and / or a plurality of powders are randomly arranged on the supporting body 2, so that at least a part of the surface of the adsorption layer 1 forms an uneven structure. Compared with the prior art in which the adsorption component 10 is directly formed by randomly piling up the adsorption particles 11, the design of randomly arranging the adsorption particles 11 on the supporting body 2 reduces the resistance to the gas, and has a better adsorption effect; and the uneven structure on the adsorption layer 1 increases the driving force of mass transfer during adsorption, so that the external gas and the adsorption layer 1 are fully in contact, thereby improving the adsorption effect and efficiency.

[0058] like Figure 1-5 As shown, at least one connecting end 401 includes two connecting ends 401; for each adsorption component 10, the support body 2 and the adsorption layer 1 are stacked on both sides of the heat conductor 3, and the adsorption layer 1 faces the gas channel 40; the thickness of the adsorption layer 1 is different at different locations, and the ratio of the maximum thickness of the adsorption layer 1 to the maximum thickness of the support body 2 is between 1-10, and the ratio of the minimum thickness of the adsorption layer 1 to the maximum thickness of the support body 2 is between 0.5-5; for each gas channel 40, the adsorption layer 1 is configured to dock with the gas entering from one of the connecting ends 401 to adsorb carbon dioxide, and make The adsorbed gas is discharged through another connecting end 401. In the present application, two adsorption layers 1 are provided on each adsorption component 10, so that the upper and lower sides of each gas channel 40 can be connected to the adsorption layer 1, thereby increasing the contact area between the gas and the adsorption layer 1, thereby improving the adsorption efficiency. In addition, the structural design of different thicknesses of the adsorption layer 1 can increase the driving force of mass transfer during adsorption. The thickness of the adsorption layer 1 also depends on the thickness of the supporting body 2. By setting the ratio between the two, both the stable support of the adsorption component 10 and the good adsorption performance of the adsorption component 10 can be achieved.

[0059] like Figure 6 , 7As shown, at least one connecting end 401 includes a connecting end 401; in three adjacent gas channels 40, the connecting end 401 at a high position and the connecting end 401 at a low position are both located on the same side of the outer shell 20, and the connecting end 401 at a middle position is located on the other side of the outer shell 20; in two adjacent gas channels 40, one gas channel 40 is configured as an air inlet channel 402, and the other gas channel 40 is configured as an air outlet channel 403; the adsorption component 10 is located between the air inlet channel 402 and the air outlet channel 403, and is used to connect the gas entering from the air inlet channel 402 and adsorb and process it, so as to output the adsorbed gas from the air outlet channel 403. The present application divides the gas before and after the treatment by adopting mutually independent air inlet channels 402 and air outlet channels 403, so as to avoid the gas before and after the treatment from being mixed and discharged together; and the gas needs to directly pass through the adsorption component 10, and its contact area with the adsorption component 10 is larger, and its adsorption effect is better.

[0060] like Figure 6 , 8 As shown, for each adsorption component 10, the adsorption layer 1, the supporting body 2 and the heat conductor 3 are arranged in sequence from the inside to the outside, and the surface of the supporting body 2 in contact with the adsorption layer 1 is a concave-convex surface. Specifically, the cross-sectional shape of the concave-convex surface is wavy or arc-shaped. In the present application, the adsorption layer 1 is wrapped in the supporting body 2 by arranging the adsorption layer 1, the supporting body 2 and the heat conductor 3 in sequence from the inside to the outside, so as to further avoid the loss of substances in the adsorption layer 1; and the surface of the supporting body 2 in contact with the adsorption layer 1 is a concave-convex surface, which increases the contact area between the adsorption layer 1 and the external gas, thereby improving the adsorption effect and efficiency.

[0061] like Figure 6-8 As shown, the heating component includes a plurality of first conductive baffles 301 and a plurality of second conductive baffles 302, and the housing 20 includes an insulating shell; the plurality of first conductive baffles 301 are spaced apart on the first side 201 of the insulating shell, and each first conductive baffle 301 corresponds to an air outlet channel 403, which is used to block the side of the air outlet channel 403 away from the connecting end 401; the plurality of second conductive baffles 302 are spaced apart on the second side 202 of the insulating shell, and each second conductive baffle 302 corresponds to an air inlet channel 402, which is used to block the side of the air inlet channel 402 away from the connecting end 401; the heat conductor 3 includes a heating element, which is connected to the first conductive baffle 301 and the second conductive baffle 302, and is used to generate heat to obtain heat when the first conductive baffle 301 and the second conductive baffle 302 are energized. The present application achieves heating of the heating element and blocking of the side of the air outlet channel 403 away from the connecting end 401 and the side of the air inlet channel 402 away from the connecting end 401 through the functions of the first conductive baffle plate 301 and the second conductive baffle plate 302. The structure is more compact and the space design is more reasonable.

[0062] like Figure 1-4 As shown, the heating component includes a heating component 303, which is arranged on the housing 20, and the heat conductor 3 includes a heat-conducting layer, which is connected to the heating component 303 and is used to obtain heat from the heating component 303. The present application indirectly heats the adsorption layer 1 through the cooperation of the heat-conducting layer and the heating component 303. Compared with the direct heating method, although there is a heat conduction temperature difference, the heating is more uniform, the temperature control fault tolerance is higher, the protection of the adsorption layer is better, and the life of the adsorption material is also improved in disguise.

[0063] like Figure 5 As shown, a filter screen 8 is provided on the housing 20, and the filter screen 8 is located at the connecting end 401, and is used to isolate substances other than gas. The present application prevents large particles from entering the housing 20 through the design of the filter screen 8, causing large particles to adhere to the surface of the adsorption component 10, affecting the contact between the gas and the adsorption component 10.

[0064] like Figure 1-8 As shown, the bonding layer 21 includes an adhesive or an adsorption structure; wherein the adsorption structure is used to capture fine particles or powder materials.

[0065] In one embodiment, Figure 3 As shown, the bonding layer 21 includes an adsorption structure with the function of capturing fine particles or powder materials. The adsorption structure is configured as a plurality of fine gaps or a large number of tiny fibers, and the heat-unstable substance 12 with adsorption activity escaping from the adsorption layer is adhered by surface tension and / or active groups. The composite board structure made by this process is more stable and does not require adhesives. In addition, the above-mentioned heat-unstable substance 12 is secondary distributed in the support body 2 and the bonding layer 21 during the use of the adsorption material, which not only protects the active components of the adsorption material, but also increases the contact area between the active components and the airflow.

[0066] In other embodiments, Figure 2 As shown, the bonding layer 21 includes an adhesive, and the adhesive is coated on the supporting body. This method is more convenient and easier to operate than processing a composite board.

[0067] The supporting body 2 includes one or more combinations of a filter cloth layer, a filter mesh layer and a breathable plate;

[0068] and / or, the heat conductor 3 has a breathable structure;

[0069] And / or, the adsorption particles 11 include solid amine particles.

[0070] In the present application, the support layer is used to provide a molding skeleton for the adsorption layer 1. Since the adsorption layer 1 is mostly adsorption particles 11, the support layer needs a molding material such as a filter cloth layer, a filter mesh layer (such as a fiber mesh, a metal mesh) and a breathable plate (such as a metal breathable plate) to provide appropriate strength for the adsorption particles 11. The support layer can also be made of composite materials, such as a combination of filter cloth and metal mesh, a combination of fiber mesh and metal plate, etc.

[0071] Among them, solid amine particles have good properties for adsorbing carbon dioxide; the design of solid amine particles allows the gas to better contact with it, increasing the contact area and improving the adsorption efficiency.

[0072] Example 1

[0073] The present application provides an embodiment of an air carbon capture adsorption device, specifically:

[0074] like Figure 1-5 As shown, the gas channel 40 has two connecting ends 401; for each adsorption component 10, the support body 2 and the adsorption layer 1 are stacked on both sides of the heat conductor 3, and the adsorption layer 1 faces the gas channel 40; the thickness of the adsorption layer 1 is different at different locations, and the ratio of the maximum thickness of the adsorption layer 1 to the maximum thickness of the support body 2 is between 4-5, and the ratio of the minimum thickness of the adsorption layer 1 to the maximum thickness of the support body 2 is between 0.7-1.5; for each gas channel 40, the adsorption layer 1 is configured to dock with the gas entering from one of the connecting ends 401 to adsorb carbon dioxide, and allow the adsorbed gas to be discharged through the other connecting end 401.

[0075] The heat conductor 3 includes a heat conducting layer, and the heating component 303 is connected to the heat conducting layer for heating the heat conducting layer and transferring the heat to the supporting body 2; the adsorption layer 1 is used to connect the heat of the supporting body 2 to release the adsorbed carbon dioxide by heat.

[0076] Among them, the heat conducting layer includes good metal conductors such as iron mesh and thin aluminum plate.

[0077] Through the above-mentioned design, the present application realizes that the gas does not need to pass through the adsorption component 10, but can directly contact the adsorption layer 1, thereby reducing the gas phase resistance and facilitating the removal of the adsorbed gas. In addition, the present application indirectly realizes the heating of the adsorption layer 1 through the cooperation of the heat conductive layer and the heating component 303. Compared with the direct heating method, although there is a thermal conductivity temperature difference, the heating is more uniform, the temperature control fault tolerance is higher, the protection of the adsorption layer is better, and the life of the adsorption material is also increased in disguise.

[0078] Furthermore, a filter screen 8 is provided on the housing 20, and the filter screen 8 is located at the connecting end 401, and is used to isolate substances other than gas; an adsorbent material is applied on the filter screen 8, and the adsorbent material is used to absorb part of the carbon dioxide in the gas. Since the adsorption layer 1 of the present application is directly exposed to the gas channel 40, the filter screen 8 is required to filter large particles. The large particles enter the interior of the housing 20, causing the large particles to adhere to the surface of the adsorption component 10, affecting the contact between the gas and the adsorption component 10.

[0079] Example 2

[0080] The present application also provides another embodiment of an air carbon capture adsorption device, specifically:

[0081] like Figure 6-8 As shown, at least one communication end 401 includes a communication end 401;

[0082] In the three adjacent gas channels 40 , the high-positioned connecting end 401 and the low-positioned connecting end 401 are both located on the same side of the housing 20 , and the middle-positioned connecting end 401 is located on the other side of the housing 20 ;

[0083] In two adjacent gas channels 40, one gas channel 40 is configured as an air inlet channel 402, and the other gas channel 40 is configured as an air outlet channel 403; the adsorption component 10 is located between the air inlet channel 402 and the air outlet channel 403, and is used to connect with the gas entering from the air inlet channel 402 and adsorb and process it, so as to output the adsorbed gas from the air outlet channel 403.

[0084] For each adsorption assembly 10, the adsorption layer 1, the supporting body 2 and the heat conductor 3 are arranged in sequence from the inside to the outside, and the surface of the supporting body 2 in contact with the adsorption layer 1 is a concave-convex surface.

[0085] like Figure 6-8 As shown, the present application uses independent air inlet channels 402 and air outlet channels 403 to divide the gases before and after processing, thereby preventing the gases before and after processing from mixing and being discharged together; and the gas needs to directly pass through the adsorption component 10, so that the contact area with the adsorption component 10 is larger and the adsorption effect is better.

[0086] Compared with the air carbon capture adsorption device provided in Example 1, the gas needs to pass through the adsorption assembly 10 during the gas treatment process. Although this causes additional resistance, thanks to the reasonable shaping design, under certain volume conditions, its gas contact area is much larger than that of Example 1, that is, the wind speed is reduced and the resistance is reduced.

[0087] like Figure 6-8As shown, further, the heating assembly includes a plurality of first conductive baffles 301 and a plurality of second conductive baffles 302, and the housing 20 includes an insulating shell; the plurality of first conductive baffles 301 are arranged at intervals on the first side 201 of the insulating shell, and each first conductive baffle 301 corresponds to an air outlet channel 403, and is used to block a side of the air outlet channel 403 away from the connecting end 401;

[0088] A plurality of second conductive baffles 302 are arranged at intervals on the second side 202 of the insulating housing, and each second conductive baffle 302 corresponds to an air inlet channel 402 and is used to block a side of the air inlet channel 402 away from the connecting end 401;

[0089] The heat conductor 3 includes a heating element, which is connected to the first conductive baffle 301 and the second conductive baffle 302 and is used to generate heat to obtain heat when the first conductive baffle 301 and the second conductive baffle 302 are powered on.

[0090] The heating element includes a heating net or a heating wire.

[0091] The present application achieves heating of the heating element and partial blocking of the air outlet channel 403 and the air inlet channel 402 through the functions of the first conductive baffle plate 301 and the second conductive baffle plate 302, so that the gas can switch from the air inlet channel 402 to the air outlet channel 403, thereby allowing the gas to pass through the adsorption component 10 and improve the contact between the gas and the adsorption component 10; the structural design is more compact and the space design is more reasonable.

[0092] The cross-sectional shape of the concave-convex surface may be a wave shape, an arc shape or the like.

[0093] The present application specially designs the adsorption component 10 so that the adsorption layer 1 is wrapped by the supporting body 2, so that the adsorption layer 1 is more evenly distributed in the inner cavity defined by the supporting body 2, thereby reducing the possibility of the substance in the adsorption layer 1 being discharged to the outside with the gas; and the design of the concave and convex surface increases the contact area between the body and the adsorption layer 1, thereby improving the adsorption effect.

[0094] The support body 2 includes a breathable filter cloth, and the sealing part of the breathable filter cloth can be processed by hot melting, gluing, sewing, etc. The heating layer includes a mesh heating filament, which has a certain mechanical strength and can be combined with the breathable filter cloth. Since the support body 2 itself has the ability to filter large substances outside the gas, it is not necessary to set the filter screen 8 at the connecting end 401 of the gas channel 40, thereby reducing costs.
