[0002] Device for adsorbing gaseous components from the air

[0003] The present invention relates to a device for adsorbing gaseous components from the air, comprising a housing with an air inlet side and an air outlet side, wherein a sorption agent, at least one heat exchanger structure, and at least two air guiding structures arranged parallel and spaced from one another to form an intermediate space and extending from the air inlet side to the air outlet side are arranged in the housing, wherein each of the air guiding structures comprises at least one air supply duct and at least one air outflow duct, wherein the at least one air supply duct has an air outlet region for the outlet of supplied air into the intermediate space, and wherein the at least one air outflow duct has an air inlet region for the entry of air from the intermediate space.

[0004] Furthermore, the present invention relates to a motor vehicle with a device for adsorbing gaseous components from the air.

[0005] In many technical fields, for example, automotive engineering, devices are used to remove gaseous components such as moisture or carbon dioxide (CO2) from the air. In particular, given the challenges of anthropogenic climate change, there is a particular need for devices for adsorbing CO2.

[0006] For the adsorption of CO2 from the air, CO2-affine adsorbent granules are used as sorbents. The adsorbent granules are loaded with CO2 from the ambient air by flowing through them at ambient temperature. When a saturation state occurs, the CO2 is desorbed from the adsorbent granules under the influence of heat. The heat is introduced via a heat exchanger.

[0007] To absorb CO2, the path length the air takes through the sorbent, also known as the flow length, must be as long as possible. However, for desorption, it is advantageous if the sorbent layer has the smallest possible thickness, also known as the bed height, so that heat transfer occurs quickly and evenly.

[0008] These two requirements of the greatest possible flow length and the smallest possible layer thickness or bed height are not compatible with each other in known devices for the adsorption of gaseous components from the air.

[0009] US 2022 / 0193598 A2 discloses a device for separating carbon dioxide from a gas stream using a bed of adsorbent particles. The adsorbent particles are contained in a sorbent volume. The device comprises at least two inlet channels and at least two outlet channels that merge into one another and are arranged parallel to each other. The inlet channels and outlet channels are arranged alternately in both lateral dimensions, so that the sorbent volume is delimited by the space defined by the adjacent side walls of the inlet and outlet channels.

[0010] The present invention is based on the object of providing a device for adsorbing gaseous components from the air, with which the amount of adsorbed gaseous components is maximized and which at the same time enables effective and energy-efficient desorption of the absorbed gaseous components.

[0011] To achieve the object underlying the invention, a device for adsorbing gaseous components from the air is proposed, comprising a housing with an air inlet side and an air outlet side, wherein a sorption agent, at least one heat exchanger structure, and at least two air guiding structures arranged parallel to one another and spaced apart from one another to form an intermediate space and extending from the air inlet side to the air outlet side are arranged in the housing, wherein each of the air guiding structures comprises at least one air supply duct and at least one air outflow duct, wherein the at least one air supply duct has an air outlet region for the outlet of supplied air into the intermediate space, wherein the at least one air outflow duct has an air inlet region for the entry of air from the intermediate space, wherein it is further provided that a separating element is arranged in the intermediate space,which divides the intermediate space into a first subspace and a second subspace, and that the sorbent is arranged in the first subspace and the second subspace.,

[0012] Air to be cleaned of gaseous components enters the housing through the air inlet side and exits the housing again through the air outlet side. This defines a main flow direction of the air through the housing from the air inlet side to the air outlet side. The at least two air guiding structures extend from the air inlet side to the air outlet side and preferably run parallel to the main flow direction. The air to be cleaned enters the at least one air supply duct of the respective air guiding structure and then exits through the air outlet region of the air supply duct into the intermediate space. The intermediate space contains the sorption agent, through which the gaseous components are absorbed or adsorbed from the air.After the air has flowed through the sorbent, the air enters through the air inlet area into at least one air outlet channel of the respective air duct structure and then exits from the air outlet side of the housing.

[0013] According to the invention, it is provided that a, preferably gas-impermeable, separating element is arranged in the intermediate space, which divides the intermediate space into a first partial space and a second partial space, and that the sorbent is arranged in the first partial space and in the second partial space.

[0014] The device according to the invention for adsorbing gaseous components from the air can be used in motor vehicles. Furthermore, the device according to the invention for adsorbing gaseous components from the air can also be used in other technical fields, particularly in stationary systems and / or large-scale plants.

[0015] The separating element is preferably designed to be gas-tight, so that no air exchange occurs between the first sub-chamber and the second sub-chamber, and no crossflow occurs between the parallel air-guiding structures. Furthermore, the separating element also preferably extends from the air inlet side to the air outlet side and parallel to the main flow direction. Thus, air supplied through the at least one air supply duct of the respective air-guiding structure is discharged from the housing again through the at least one air discharge duct of the same air-guiding structure.

[0016] The flow length, i.e. the path length through which the air flows for the absorption or adsorption of the gaseous component by the sorbent, thus essentially corresponds to the distance between the air outlet region of the at least one air supply duct and the air inlet region of the at least one air outflow duct of the respective air duct structure. The bed height, i.e. the layer density of the sorbent through which the heat transfer for the desorption of the gaseous component takes place, is preferably determined by the distance of the separating element from the air duct structures delimiting the intermediate space. Therefore, a decoupling or separation of the flow length and the bed height takes place, meaning that the flow length and the bed height can be selected or adjusted independently of one another.The separating element particularly prevents crossflow of air through the sorbent between the adjacent air guide structures. If crossflow does not occur according to the invention, the flow length determined by the distance between the adjacent air guide structures would simultaneously correspond to the layer thickness to be heated, i.e., the bed height of the sorbent. Preventing such crossflow between the air guide structures thus enables the decoupling or separation of the flow length and bed height.

[0017] The air outlet region of the at least one air supply duct and / or the air inlet region of the at least one air outflow duct are preferably designed such that the sorbent, preferably in granular form, cannot enter the at least one air supply duct and / or the at least one air outflow duct. The air inlet region and / or the air outlet region can be designed, for example, as a perforated plate or as a grid.

[0018] The sorbent can be an adsorbent granulate, preferably a CO2-affine adsorbent granulate and / or a water-affine adsorbent granulate.

[0019] The sorbent can comprise a plastic, in particular a polymer. The polymer can particularly preferably be silica or SAA. The gaseous component is further advantageously CO2. Accordingly, the device for adsorbing gaseous components from the air can be designed as a CO2 adsorber. Furthermore, it is also possible for the gaseous component to be water in the gaseous phase. Accordingly, the device for adsorbing gaseous components from the air can be designed as an air dryer.

[0020] Each air duct structure may also include multiple air supply ducts and multiple air discharge ducts.

[0021] In principle, it is possible for the device for adsorbing gaseous components from the air to have only one air guide structure and one heat exchanger structure, with a gap formed between the air guide structure and the heat exchanger structure, and the sorbent disposed in the gap. In this case, a separating element can be omitted.

[0022] Preferably, at least three air guiding structures arranged parallel and spaced apart from one another are provided, wherein an intermediate space is formed between each two of the air guiding structures, wherein a separating element is arranged in each intermediate space, which divides the respective intermediate space into a first sub-space and a second sub-space, and wherein the sorption agent is arranged in each of the first sub-space and in the second sub-space.

[0023] In particular, a plurality of air guiding structures, for example four, five, six or more, can be provided. In each case, two of the air guiding structures are arranged parallel and spaced from one another, each forming an intermediate space. A separating element is arranged in each of the intermediate spaces, which divides the respective intermediate space into a first sub-space and a second sub-space. In other words, the device for adsorbing gaseous components is constructed in layers essentially in an extension viewed transversely to the main flow direction, wherein a first air guiding structure is followed by a first sub-space of an intermediate space, a separating element, a second sub-space of the intermediate space, and then a second air guiding structure. The second air guiding structure is again followed by a first sub-space, a separating element, a second sub-space, and a third air guiding structure.This layering can be continued depending on the planned number of air duct structures.

[0024] Furthermore, it can preferably be provided that the at least one air supply duct has an air inlet opening arranged on the air inlet side, and that an end of the air supply duct arranged on the air outlet side is closed, and that the at least one air outflow duct has an air outlet opening arranged on the air outlet side and that an end of the air outflow duct arranged on the air inlet side is closed.

[0025] If the air supply duct is closed on the air outlet side of the housing, the air entering the inlet opening and to be cleaned can only enter the intermediate space, the first subspace, or the second subspace through the air outlet area of ​​the air supply duct and must therefore flow through the sorbent located there. Accordingly, the air introduced into the sorbent can only leave the intermediate space, the first subspace, or the second subspace through the air inlet area of ​​the air outlet duct and must exit the device's housing again through the air outlet opening of the air outlet duct.

[0026] With further advantage, it can be provided that the air guiding structures are plate-shaped and / or block-shaped and preferably have flat and / or level side surfaces.

[0027] The air guiding structures are further preferably designed in an approximately cuboid shape. The air guiding structures extend from the air inlet side to the air outlet side parallel to the main flow direction. Further preferably, the air guiding structures extend in a first direction or extent transverse to the main flow direction from a first side, for example a lower side, of the housing to a second side, for example an upper side, of the housing. As a result, an interior of the housing is divided into regions in a second direction or extent perpendicular to the main flow direction and the first direction or extent, so that a layered structure of the device is formed. Due to the flat or planar side surfaces of the air flow structures, there are no pockets or dead areas within the housing in which the sorbent can be enclosed.This makes it easier to fill or empty the device of the sorbent.

[0028] The air inlet area of ​​the air supply duct and / or the air outlet area of ​​the air discharge duct can be located in the side surfaces of the respective air duct structure.

[0029] It is further advantageously provided that the at least one air supply duct and the at least one air outflow duct are arranged next to one another in an extension plane of the respective air guiding structure.

[0030] The air duct structures, which are preferably plate-shaped, block-shaped, or cuboid-shaped, have a length, preferably measured along the main flow direction, and a width, preferably measured along a first direction or extent running transversely to the main flow direction. A thickness of the air duct structures, measured along a second direction or extent running transversely to the main flow direction and transversely to the first direction or extent, is substantially smaller than the length and width. The length and width of the air duct structures define an extension plane of the respective air duct structure. The at least one air supply duct and the at least one air outflow duct are then preferably arranged next to one another in this extension plane.In the housing, the at least one air supply duct and the at least one air outflow duct of the respective air guiding structure are arranged next to one another or one above the other, as seen perpendicular to the main flow direction.

[0031] It can be further advantageously provided that no sorption agent is arranged in the air guiding structures, preferably between the at least one air supply duct and the at least one air outflow duct of the respective air guiding structure.

[0032] Thus, the adsorption of the gaseous component from the air takes place exclusively by the sorption agent arranged in the intermediate space or in the first sub-space and / or the second sub-space, which facilitates a decoupling or separation of the flow length and the bed height.

[0033] Furthermore, it can be provided that the at least one air supply channel and the at least one air outflow channel have a common wall.

[0034] If an air duct structure comprises multiple air supply ducts and multiple air discharge ducts, the air supply ducts and the air discharge ducts can be arranged alternately next to one another in the plane of extension of the air duct structure. If multiple air supply ducts and multiple air discharge ducts are provided, a common wall can be provided between adjacent air supply ducts and air discharge ducts.

[0035] With further advantage, it can be provided that the separating element comprises the heat exchanger structure and / or that the separating element is the heat exchanger structure.

[0036] In other words, the heat exchanger structure is arranged in the space between the air duct structures. This allows heat to be transferred from the heat exchanger structure into the sorbent for desorption of the gaseous components particularly efficiently.

[0037] With further advantage, it can be provided that the heat exchanger structure is plate-shaped and / or block-shaped and preferably has flat and / or level side surfaces.

[0038] If both the side surfaces of the air guidance structures and the separating element are flat or planar, this facilitates easy filling or emptying of the device housing.

[0039] With further advantage, it can be provided that the separating element is a separating plate.

[0040] The separating element can thus also be designed as a simple separating plate, meaning, in particular, that the separating element does not encompass the heat exchanger structure or is not the heat exchanger structure. In this case, the heat exchanger structure can be integrated into the air duct structure.

[0041] It can preferably be provided that the heat exchanger structure comprises at least one heat transfer channel, and that the at least one heat transfer channel is arranged integrated in the common wall of the at least one air supply channel and the at least one air outflow channel.

[0042] By means of the heat transfer channel of the heat exchanger structure integrated into the common wall, the air flowing into the air supply channel can be heated, and the heated air can be used to heat the sorbent. At the same time, heat can be transferred directly from the heat transfer channel to the sorbent arranged in the intermediate space, the first subspace, or the second subspace via the side surfaces of the air guide structure.

[0043] It is further advantageous that the at least one heat transfer channel is arranged in a serpentine or wave-like manner in the air guide structure.

[0044] The heat transfer channel is particularly preferably located in the plane of extension of the air duct structure. If multiple air supply channels and / or air outflow channels are present in the respective air duct structure, it can be provided that the heat transfer channel runs in a wall of a first air supply channel and is guided over the closed end of the first air supply channel and then continues in the wall between the first air supply channel and an adjacent first air outflow channel. The heat transfer channel can then run over the closed end of the first air outflow channel and then continue in a further wall located between the first air outflow channel and an adjacent second air supply channel.

[0045] Furthermore, it can preferably be provided that the at least one air supply duct tapers from the air inlet side towards the air outlet side, and that the at least one air outflow duct tapers from the air outlet side towards the air inlet side. Since air exits through the air outlet region of the air supply duct into the intermediate space or the first sub-space or the second sub-space, the flow velocity of the air entering the air supply duct continuously decreases towards the end arranged on the air outlet side. By tapering and the associated reduction in the cross-section of the air supply duct, a constant flow velocity can also be ensured towards the end of the air supply duct located on the air outlet side. The same applies to the air outflow duct.

[0046] It can be further advantageously provided that the separating element and / or the air guiding structures have guide plates, wherein the guide plates protrude into the intermediate space, in particular into the first partial space and / or into the second partial space.

[0047] Due to the relative arrangement of the air inlet and outlet areas of the air supply ducts and air outflow ducts, there may be areas within the intermediate space or the first subspace and / or the second subspace that are located in a flow shadow and are only slightly penetrated by air. By arranging baffles extending into the intermediate space or the first subspace and / or the second subspace, the air flow can be advantageously influenced and, for example, directed specifically into or away from the flow shadow areas.

[0048] A further solution to the problem underlying the invention lies in the provision of a motor vehicle with a device as described above for adsorbing gaseous components of the air.

[0049] The invention is explained in more detail below with reference to the accompanying figures.

[0050] Fig. 1A shows a first device for adsorbing gaseous components from the air in a cross-sectional view,

[0051] Fig. 1B shows the first device for adsorbing gaseous components from the air in a sectional view, Fig. 2A shows a second device for adsorbing gaseous components from the air in a cross-sectional view,

[0053] Fig. 3 shows an air guide structure for a device for adsorbing gaseous components from the air, and

[0054] Fig. 4 a motor vehicle with a device for adsorbing gaseous components from the air.

[0055] In the figures, the same or corresponding features are identified by the same reference numerals.

[0056] Fig. 1A shows a cross-sectional view of a device 100 for adsorbing gaseous components from the air. Figure 1B shows the device 100 of Figure 1A in a sectional view along line AA of Figure 1A.

[0057] The device 100 comprises a housing 10 with an air inlet side 11 and an air outlet side 12 (Fig. 1B). The air inlet side 11 and the air outlet side 12 define a main flow direction 13 for the air to be purified of its gaseous components. A sorption agent 14 and a heat exchanger structure 15 are arranged in the housing 10. Furthermore, a plurality of air guide structures 16 are arranged in the housing 10. Two of the air guide structures 16 are arranged parallel and spaced from one another, forming an intermediate space 17, and extend from the air inlet side 11 to the air outlet side 12 approximately parallel to the main flow direction 13. Each of the air guide structures 16 has a plurality of air supply channels 18 and a plurality of air outflow channels 19. The air supply ducts 18 and air discharge ducts 19 of each air guide structure 16 are arranged in an extension plane 20 (Fig.1B) of the respective air duct structure 16 are arranged adjacent to one another and alternately. Due to the arrangement of the air supply ducts 18 and air outflow ducts 19, the air duct structures 16 are approximately plate- or block-shaped. The air duct structures 16 have flat or planar side surfaces 21. The air supply ducts 18 further each have an air outlet region 22 for the outlet of supplied air into the intermediate space 17. Likewise, each of the air outflow ducts 19 has an air inlet region 23 for the entry of air from the intermediate space 17 into the air outflow duct 19. The air outlet regions 22 and air inlet regions are arranged in the side surfaces 21 of the air duct structures 16 and are designed in the form of perforated grids 24.In the spaces 17 between adjacent air guide structures 16, a separating element 25 is arranged, which divides the respective space 17 into a first subspace 26 and a second subspace 27. The separating elements 25 also comprise the heat exchanger structures 15 and, in particular, their heat transfer channels 28. The sorption agent 14 is arranged exclusively in the first subspaces 26 and the second subspaces 27.

[0058] As can be seen particularly in Fig. 1B, each air supply duct 18 has an air inlet opening 29 arranged on the air inlet side 11. At the end arranged on the air outlet side 12, the respective air supply duct 18 is closed. Each air outflow duct 19 has an air outlet opening 30 on the air outlet side 12 and is closed at the end arranged on the air inlet side 11.

[0059] The air to be purified of its gaseous components enters the air supply ducts 18 through the air inlet openings 29 and subsequently through the air outlet regions 22 of the air guide ducts 18 into the intermediate space 17 or into the first subspace 26 or the second subspace 27. The air then flows through the sorption agent 14 arranged in the first subspace 26 or the second subspace 27 and subsequently through the air inlet region 23 of an adjacent air outflow duct 19 and then exits the housing 10 of the device 100 through the air outlet openings 30 on the air outlet side 12. The distance 31 that the air takes through the sorbent 14 is the flow length 32. The distance 33 between the air guiding structures 16 and the separating element 25 designed as a heat exchanger structure 15 is referred to as the layer thickness or filling height 34.Due to the arrangement of air guide structures 16 and separating elements 25, the flow length 32 and the bed height 34 are aligned substantially perpendicular to one another and can be adjusted independently of one another by selecting the distances between the air supply ducts 18 and air outflow ducts 19, or between the air guide structures 16 and the separating elements 25. This has the advantage that, on the one hand, a large flow length 32 can be provided, whereby the device 100 has a high adsorption potential for the gaseous components of the air, and, on the other hand, that the bed height 34 can be minimized, whereby the heat input into the sorbent 14 required for the desorption of the gaseous components can be achieved more efficiently and evenly by means of the heat exchanger structures 15.The air supply ducts 18 and air outflow ducts 19 arranged adjacently within an air duct structure 16 have common walls 35 so that no sorbent 14 can penetrate between the air supply ducts 18 and air outflow ducts 19.

[0060] 2A and 2B show a further device 100 for adsorbing gaseous components of the air. In contrast to the device 100 according to FIGS. 1A and 1B, the separating element 25 is not designed as a heat exchanger structure 15 but as a simple separating plate 36. The heat exchanger structures 15, however, are integrated into the air guiding structures 16, with the heat transfer channels 28 running in the common walls 35 of the adjacent air supply channels 18 and air outflow channels 19. The heat transfer channels 28 of the heat exchanger structures 15 run in a serpentine manner through the air guiding structures 16, as can be seen particularly in FIG. 2A. Baffles 37 are provided on the air guiding structures 16 and extend into the intermediate spaces 17 or into the first sub-spaces 26 and into the second sub-spaces 27.The guide plates 37 serve to influence the air flow in the first sub-chambers 26 and in the second sub-chambers 27 in order to ensure the most homogeneous flow through the sorbent 14 possible.

[0061] Fig.3 shows a variant of an air guiding structure 16. In the air guiding structure 16 according to Fig. 3, the air supply ducts 18 taper from the air inlet side 11 towards the air outlet side 12. Correspondingly, the air outflow ducts 19 taper from the air outlet side 12 towards the air inlet side 11. This compensates for the continuously decreasing or increasing air flow in the air supply ducts 18 and air outflow ducts 19, so that a substantially constant flow velocity can be ensured over the entire length of the air supply ducts 18 or air outflow ducts 19.
