Background Art

[0003]

[0003] The need for technologies to remove carbon dioxide from ambient air is well established. To avoid the imminent climate change crisis, it is necessary to remove a significant amount of carbon dioxide from the atmosphere in addition to conservation, carbon reduction processes, and in-situ recovery efforts. Nevertheless, these technologies are still new and the operation of the initial air recovery processes requires a large amount of energy. Since carbon dioxide in ambient air is very dilute, carbon dioxide collection devices in the atmosphere can quickly exceed a stringent energy budget for sucking and processing large amounts of air. Furthermore, conventional carbon dioxide collection systems often have the unfortunate combination of being expensive and fragile. In addition, conventional capture devices often require a large initial capital cost and high operating costs.

Summary of the Invention

[0004]

[0004] According to one embodiment, a passive carbon dioxide collection device includes a release chamber and a capture structure coupled to the release chamber, having at least three straps and a plurality of discs coupled to and spaced apart along the at least three straps. Each disc contains an adsorbent material. The capture structure is movable between the collection configuration and the release configuration. Each strap has a primary width and a secondary width, the secondary width being at least an order of magnitude smaller than the primary width. The device also includes a movable part configured to move the capture structure between the collection configuration and the release configuration. The collection configuration includes the capture structure extending upward from the release chamber. The plurality of discs are suspended from the movable part by at least three straps such that, for each pair of adjacent discs of the plurality of discs having a lower disc and an upper disc, and for each strap of the at least three straps, the lower disc is separated from the upper disc by a connecting segment of the strap, exposing at least a portion of the capture structure to an airflow, and allowing the adsorbent material of the plurality of discs to capture carbon dioxide. The release configuration includes a plurality of disks fully stacked within a release chamber for regeneration, resulting in the release of carbon dioxide adsorbed on an adsorbent material, with each strap of at least three straps collapsing, and each connecting segment adopting a release topology, the release topology being sized and positioned to fully accommodate the stack of the plurality of disks within the release chamber. For each pair of adjacent disks of the plurality of disks, and for each strap of at least three straps, if the lower disk is not fully supported by at least three straps, the connecting segment is biased to move toward the release topology.

[0005]

[0005] A particular embodiment may have one or more of the following features: While in the discharge configuration, the multiple disks are stacked in the discharge chamber such that the gap between adjacent disks is no more than three times the secondary width, and the gap may be the maximum vertical distance between adjacent disks. The capture structure may include at least six straps. The multiple disks may be detachably coupled to at least three straps. For each disk of the multiple disks, each strap of at least three straps may be detachably coupled to the edge of the disk by a belt around the disk, pushing the strap into the edge and detachably coupling the strap to the disk. For each disk of the multiple disks and each strap of at least three straps, the disk includes an opening for the strap, through which the strap passes, and the disk may be detachably coupled to the strap near the opening. For each disk of the multiple disks and each strap of at least three straps, the strap may be detachably coupled to the disk at least partially via a self-tightening clamp inside the opening of the disk through which the strap passes. Each self-tightening clamp may be released from the strap and made movable relative to the strap by lifting the disk upward relative to the strap. The self-tightening clamp includes two textured rotating wedges, and the strap can pass between them such that the upward movement of the strap relative to the self-tightening clamp causes the wedges to rotate in the direction of the strap's movement, gripping the strap and removably coupling the disc to the strap. For each disc of the multiple discs and each strap of at least three straps, the disc may be coupled to the strap via a stopper removably coupled to the strap below the disc, but the stopper is too large to fit into the opening through which the strap passes. Each of the at least three straps may be enclosed in a different sleeve. Each sleeve may be made of an elastic material and may be biased to contract from an extended state corresponding to the capture structure in the collection configuration to a relaxed state corresponding to the capture structure in the release configuration.For each of the at least three straps, the relaxed state of the sleeve may be contained within a passage bounded by an opening through which the strap passes, and as a result, when the capture structure is in the release configuration, the release topology may contain the strap contained within the passage by the sleeve. For each pair of adjacent disks of the plurality of disks, and for each of the at least three straps, the release topology of the strap's connecting segment may include a connecting segment that folds to form a folded edge sandwiched between the upper and lower disks. For each pair of adjacent disks of the plurality of disks, at least one of the upper and lower disks may include a groove of a size and position that at least partially receives the connecting segment when in the release topology. For each pair of adjacent disks of the plurality of disks, and for each of the at least three straps, the release topology of the strap's connecting segment may include a connecting segment that folds to form a folded edge in the gap between the plurality of disks and the release chamber. For each of the at least three straps, the strap may include a uniform strap, and each connecting segment of the strap may include a uniform strap coupled to at least one biasing strap. The biasing strap may be made of an elastic material. For each of the at least three straps, each connecting segment of the strap may include two biasing straps separated by breakage. The at least three straps can pass through multiple disks, and the primary width of each strap has a orientation with respect to the radius of the disk that bisects the primary width, and the orientation of the at least three straps breaks the rotational symmetry of the capture structure, preventing rotation by airflow. The at least three straps can pass through multiple disks in a tangential manner, and the primary width of each strap has a orientation with respect to the radius of the disk that bisects the primary width. The orientation of the primary width may be closer to perpendicular to the radius than parallel to the radius.At least three straps can pass through multiple disks in a radial manner, and the primary width of each strap has a orientation with respect to the radius of the disk that bisects the primary width. The orientation of the primary width may be closer to parallel with the radius than perpendicular to the radius.

[0006]

[0006] According to another aspect of the present disclosure, a passive carbon dioxide collection device includes a release chamber and a capture structure coupled to the release chamber and having at least six straps and a plurality of discs detachably coupled to the at least six straps and spaced apart along the at least six straps. Each disc has an adsorbent material and at least three openings through the disc, and each strap passes through a different opening of the at least three openings of each disc. The capture structure is movable between the collection configuration and the release configuration, and each strap has a primary width and a secondary width, the secondary width being at least an order of magnitude smaller than the primary width. The device also includes a movable part configured to move the capture structure between the collection configuration and the release configuration. The collection configuration includes a capture structure extending upward from the release chamber and a plurality of discs suspended from the movable part by at least six straps, such that for each pair of adjacent discs of the plurality of discs having a lower disc and an upper disc, and for each strap of the at least six straps, the lower disc is separated from the upper disc by a connecting segment of the strap, exposing at least a portion of the capture structure to an airflow, and allowing the adsorbent material of the plurality of discs to capture carbon dioxide. The release configuration includes a plurality of disks fully stacked within a release chamber for regeneration, resulting in the release of carbon dioxide adsorbed on an adsorbent material, and each of the at least six straps collapses, and each connecting segment has a release topology having a connecting segment that folds to form a folded edge sandwiched between an upper disk and a lower disk defining the connecting segment, and the release topology is sized and positioned such that the stack of the plurality of disks is fully contained within the release chamber. For each pair of adjacent disks in the plurality of disks and for each strap of the at least six straps, if the lower disk is not fully supported by the at least six straps, the connecting segment is biased to move toward the release topology. For each disk in the plurality of disks and for each strap of the at least six straps, the disk is removably coupled to the strap near an opening through which the strap passes.

[0007]

[0007] A particular embodiment may have one or more of the following features: While in the discharge configuration, the plurality of disks may be stacked in the discharge chamber such that the gap between adjacent disks is no more than three times the secondary width, where the gap is the maximum vertical distance between adjacent disks. For each disk of the plurality of disks and each strap of the at least six straps, the strap may be removably coupled to the disk at least partially via a self-tightening clamp inside the opening of the disk through which the strap passes. Each self-tightening clamp may be disengaged from the strap and made movable relative to the strap by lifting the disk upward relative to the strap. For each disk of the plurality of disks and each strap of the at least six straps, the disk may be coupled to the strap via a stopper removably coupled to the strap below the disk, but the stopper is too large to fit into the opening through which the strap passes. Each strap of the at least six straps may be enclosed in a different sleeve. Each sleeve may be made of an elastic material and may be biased to contract from an extended state corresponding to the capture structure in the collection configuration to a relaxed state corresponding to the capture structure in the discharge configuration. For each of the at least six straps, the relaxed state of the sleeve may be contained within a passage bounded by an opening through which the strap passes; therefore, when the capture structure is in a release configuration, the release topology may include a strap housed within the passage by the sleeve. For each pair of adjacent disks of the plurality of disks, and for each of the at least six straps, the release topology of the strap's connecting segment may include a connecting segment that folds to form a folded edge sandwiched between the upper and lower disks. For each of the at least six straps, the strap may include a uniform strap, and each connecting segment of the strap may include a uniform strap coupled to at least one biasing strap. The biasing strap may be made of an elastic material.For each of the at least six straps, each connecting segment of the strap may include two biasing straps separated by breakage. The at least six straps can pass through multiple disks, and the primary width of each strap has a orientation with respect to the radius of the disk that bisects the primary width. The orientation of the at least six straps may break the rotational symmetry of the capture structure and hinder rotation by airflow. The at least six straps can pass through multiple disks in a tangential manner, and the primary width of each strap has a orientation with respect to the radius of the disk that bisects the primary width. The orientation of the primary width may be closer to perpendicular to the radius than parallel to the radius. The at least six straps can pass through multiple disks in a radial manner, and the primary width of each strap has a orientation with respect to the radius of the disk that bisects the primary width. The orientation of the primary width may be closer to parallel to the radius than perpendicular to the radius.

[0008]

[0008] According to yet another aspect of the present disclosure, a method for suspending adsorption disks within a passive carbon dioxide collector comprises coupling at least three straps to a movable part of the passive carbon dioxide collector and to the release chamber of the passive carbon dioxide collector. Each strap has a primary width and a secondary width, the secondary width being at least an order of magnitude smaller than the primary width. The movable part is configured to move a capture structure having at least three straps and a plurality of disks between a capture configuration and a release configuration, each disk of the plurality of disks having an adsorption material. The method also comprises coupling the plurality of disks to at least three straps such that the plurality of disks are suspended from the movable part by at least three straps when the capture structure is in the capture configuration. The plurality of disks are spaced apart along at least three straps such that each pair of adjacent disks of the plurality of disks having a lower disk and an upper disk, and for each strap of the at least three straps, the lower disk is separated from the upper disk by a connecting segment of the strap. This method involves biasing at least three straps such that, for each pair of adjacent disks of a plurality of disks and each strap of at least three straps, the connecting segment is biased to move toward the release topology when the lower disk is not fully supported by at least three straps. The release topology is set to a size and position that can accommodate a capture structure that moves consistently toward the release configuration. The collection configuration includes a capture structure extending upward from the release chamber and a plurality of disks suspended from the movable part by at least three straps, exposing at least a portion of the capture structure to an airflow so that the adsorbent material of the plurality of disks can capture carbon dioxide. The release configuration includes a plurality of disks fully stacked within the release chamber for regeneration resulting in the release of carbon dioxide adsorbed on the adsorbent material, with each strap of at least three straps collapsing and each connecting segment taking on the release topology.

[0009]

[0009] A particular embodiment may have one or more of the following features: While in the discharge configuration, the multiple disks may be stacked in the discharge chamber such that the gap between adjacent disks is no more than three times the secondary width, where the gap is the maximum vertical distance between adjacent disks. The capture structure may include at least six straps. The multiple disks may be removably coupled to at least three straps. Coupled multiple disks to at least three straps may include, for each disk of the multiple disks, removably coupling each strap of at least three straps to the edge of the disk with a belt around the disk, and pushing at least three straps into the edge. Coupled disks to straps for each disk of the multiple disks and each strap of at least three straps may include passing the straps through different openings of at least three openings and / or removably coupling the straps to the disk near the openings. Coupled disks to straps for each disk of the multiple disks and each strap of at least three straps may include passing the straps through at least partially self-tightening clamps inside the openings of the disk through which the straps pass. This method may further include disengaging the self-tightening clamps and making the discs movable relative to the straps by lifting the discs upward relative to the straps for each disc of the multiple discs and each strap of at least three straps. The self-tightening clamps may include two textured rotating wedges, and the straps pass between them so that the upward movement of the straps relative to the self-tightening clamps causes the wedges to rotate in the direction of the strap's movement, clamping the straps and allowing the discs to be detachably coupled to the straps.For each disk of the plurality of disks and each strap of at least three straps, the detachable coupling of the strap to the disk near the opening may include detachable coupling of a stopper to the strap below the disk so that the stopper is too large to fit through the opening through which the strap passes. This method may further include enclosing each strap of at least three straps in a different sleeve. Each sleeve may be made of an elastic material and may be biased to contract from an extended state corresponding to a capture structure in a collection configuration to a relaxed state corresponding to a capture structure in a release configuration. For each strap of at least three straps, the relaxed state of the sleeve may be contained within a passage bounded by the opening through which the strap passes, so that when the capture structure is in a release configuration, the release topology may include a strap housed within the passage by the sleeve. For each pair of adjacent disks of the plurality of disks and for each strap of at least three straps, the release topology of the strap's connecting segment may include a connecting segment that folds to form a folded edge sandwiched between the upper and lower disks. The method may further include forming each disk of the plurality of disks to have at least three grooves, so that for each pair of adjacent disks of the plurality of disks and for each of the at least three straps, at least one groove may be set to a size and position such that it at least partially receives a connecting segment when in the discharge topology. For each pair of adjacent disks of the plurality of disks and for each of the at least three straps, the discharge topology of the strap connecting segment may include a connecting segment that folds to form a folded edge in the gap between the plurality of disks and the discharge chamber. Each of the at least three straps may include a uniform strap. Biasing the at least three straps may include coupling at least one biasing strap to each connecting segment of the straps. The biasing strap may be made of an elastic material.For each of the at least three straps, each connecting segment of the strap may include two biasing straps separated by breakage. This method may further include passing at least three straps through a plurality of disks. For each disk in the plurality of disks, the primary width of each strap may have orientation with respect to the disk radius that bisects the primary width. The orientation of at least three straps may break the rotational symmetry of the capture structure and prevent rotation caused by airflow. This method may further include passing at least three straps through the plurality of disks in a tangential manner. For each disk in the plurality of disks and each of the at least three straps, the tangential manner includes the primary width of the strap having orientation with respect to the disk radius that bisects the primary width, and the orientation of the primary width is closer to perpendicular to the radius than parallel to the radius. This method may further include passing at least three straps through the plurality of disks in a radial manner. For each disk of the plurality of disks and each of the at least three straps, the radial aspect may include the primary width of the strap having a directionality with respect to the radius of the disk that bisects the primary width, wherein the directionality of the primary width is closer to parallel with the radius than perpendicular with respect to the radius.

[0019]

[0025] The need for technologies to remove carbon dioxide-132 from the ambient air is well established. To avert the impending climate change crisis, a significant amount of carbon dioxide-132 needs to be removed from the atmosphere, in addition to conservation, carbon reduction processes, and on-site capture efforts. Nevertheless, these technologies are still new, and the operation of initial air capture processes requires a large amount of energy. Because carbon dioxide-132 in the ambient air is extremely dilute, atmospheric carbon dioxide-132 capture devices can quickly exceed the tight energy budget required to draw in and process large volumes of air. Furthermore, conventional carbon dioxide-132 capture systems often exhibit the unfortunate combination of being expensive and fragile. Conventional capture devices also often have high initial capital costs along with high operating costs.

[0020]

[0026] Figures 1A, 1B, and 1C are various diagrams of non-limiting examples of a device 100 (hereinafter referred to as device 100 or collection device 100) for passive collection of atmospheric carbon dioxide 132, which is movable between two configurations. Specifically, Figure 1A is a perspective view of a non-limiting example of device 100. Figures 1B and 1C show non-limiting examples of collection device 100 in a collection 118 configuration and an emission 120 configuration, respectively. This architecture has many advantages over conventional collection devices 100. According to various embodiments, it is energy efficient, durable, and can be adapted for use in various environments.

[0021]

[0027] As shown, the apparatus 100 includes a capture structure 106 comprising a plurality of discs 110 containing an adsorbent material 112 that can capture and later release carbon dioxide 132. These discs 110 are suspended from a lid 104 or other movable part 126 of the apparatus 100, which is located above the release chamber 102. While in the collection configuration 118 (i.e., Figure 1B), the capture structure 106 is expanded so that the discs 110 are spread over the release chamber 102, and its adsorbent material 112 is exposed to the atmosphere (e.g., natural airflow, forced airflow) where it captures carbon dioxide 132. Once the discs 110 are filled with carbon dioxide 132, the capture structure 106 is moved to the release configuration 120 (i.e., Figure 1C), where the discs 110 are stacked inside the release chamber 102. The stacked disks 110 are sealed within the release chamber 102 (for example, a lid 104 on which the disks 110 are suspended is lowered onto the release chamber 102), where they undergo a regeneration cycle that releases the captured carbon dioxide 132 into the chamber, where it is recovered and stored as concentrated carbon dioxide. Once the disks 110 have been regenerated and the released carbon dioxide 132 has been collected, the capture structure 106 is returned to the collection configuration 118, and the cycle is repeated. The nature of the regeneration cycle depends on the type of adsorption material 112 used (e.g., thermal swing, moisture swing, electrical swing, pressure swing, etc.).

[0022]

[0028] In the context of this description, the disk 110 is made of or a structure capable of holding a carbon dioxide adsorption material 112, such as a moisture-swinging material or a thermal-swinging material. While the disk 110 is shown as circular in the following description and figures, it should be noted that the methods, apparatus, and structures intended herein can be adapted for use with disks 110 of any shape.

[0023]

[0029] Furthermore, although the following description and figures depict the disk 110 as a flat surface (i.e., a short, wide cylinder), it should be noted that the disk 110 can have a variety of cross-sections, including cross-sections that are not perfectly flat. For example, in some embodiments, the bottom of each disk may have feet for resting on the surface of the next disk 100, so that when stacked there is a gap between the disks, allowing fluid communication between the release chamber 102 and the adsorbent material 112 of the disk 110, facilitating the regeneration of the adsorbent and the release of the captured adsorbent gas. Some disks may be a single, one-piece structure, while others may consist of multiple parts. Those skilled in the art will recognize that the apparatus and methods contemplated herein can be adapted for use with adsorbent disks having any shape or profile.

[0024]

[0030] The carbon dioxide capture capacity and operating efficiency depend, at least in part, on the total surface area of ​​the adsorbent exposed to the atmosphere while in the collection configuration 118, and similarly on minimizing the resources (e.g., electricity, heat, water, etc.) used during the regeneration cycle while in the release configuration 120. The advantages of this architecture over conventional collection devices 100 are amplified, according to various embodiments, as the total disk surface area increases and the total volume of the release chamber 102 decreases.

[0025]

[0031] Many methods and structures can be used to hold the disk 110 in the collection configuration 118 and to move the disk 110 between the collection configuration 118 and the discharge configuration 120. For example, in some embodiments, rigid systems (e.g., hydraulics, tracks, actuators, etc.) can be used. However, these systems tend to be large and heavy. Suspending the disk 110 from the lid 104 by multiple tethers and moving the lid 104 up and down is far simpler and more flexible than a rigid system. However, even with the advantages of using flexible tethers, a new set of problems arise when trying to improve the efficiency and effectiveness of the collection device 100 beyond a certain point. This is best illustrated by non-limiting examples of specific embodiments of the passive collection device 100.

[0026]

[0032] According to one embodiment, the passive collection device 100 can use 150 disks 110, each 1 cm thick. Although each disk 110 weighs only a few kilograms, the total weight of the stack of disks 110 is considerable, potentially ranging from 0.5 to several tons. Tethering each disk 110 to an adjacent disk is impractical because supporting this total weight with a single disk 110 (e.g., the disk at the top of the stack) would require using a disk 110 that is inefficient if possible (e.g., a heavier, more expensive disk). However, coupling each disk 110 to the same set of tethers extending along the length of the capture structure 106 would require each disk 110 to support only its own weight. This allows the collection device 100 to utilize a larger number of disks 110, increasing the total surface area.

[0027]

[0033] As mentioned above, another factor in the overall efficiency and effectiveness of the device 100 is minimizing the volume of the discharge chamber 102, which can be achieved by reducing the space required to surround the stack of disks 110 when in the discharge configuration 120. This means that the strength of the tethers must be balanced with their physical size and shape. Small tethers may lack sufficient strength and require more of them, and may obstruct the necessary airflow in both the collection 118 configuration and the discharge 120 configuration. Large tethers may have sufficient strength to hold the entire stack of disks 110, but may be too large to fit within the space between disks 110 when stacked in the discharge configuration.

[0028]

[0034] Returning to a specific, non-limiting example, 150 disks 110, each 1 cm thick, are spaced 4 cm apart while in the collection configuration 118, and only 0.5 cm apart when stacked in the release configuration. This results in a capture structure 106 with a height range from approximately 2 m in the release configuration 120 to approximately 7 m in the collection configuration 118. This means that when in the release configuration 120, the approximately 4 cm tether must fold between adjacent disks 110 or otherwise collapse and fit into the 0.5 cm gap 208 between the disks 110, so that no excessive force is applied to the tether and there is no possibility of the tether getting caught between the disks 110 and preventing proper stacking. Flexible tethers with a radial cross-section that is nearly equal in all directions (e.g., cylindrical cables) tend to be bulky and their folding is unpredictable.

[0029]

[0035] This specification envisions apparatus and methods for passive carbon dioxide collection using adsorption discs 110 suspended using flexible straps 108. According to various embodiments, advantageously, supporting the discs 110 using these straps 108 facilitates the raising of the discs 110 and the lowering of the discs 110 into the chamber without exposure to airflow 130 or interference by the straps 108 due to a dense stack of discs 110. A small number of straps 108 are strong enough to support the weight of the entire disc stack by their primary width 122 and thin enough to collapse between the discs 110 when stacked.

[0030]

[0036] The following description is made in the context of suspending a series of carbon dioxide adsorption disks 110, but the apparatus, structure, and method intended herein can be adapted for use in any other example in which a series of disks 110 or plates are movable between an extended configuration and a collapsed configuration, while efficiently utilizing space and operating reliably in a predictable manner.

[0031]

[0037] Hereinafter, the flexible tether discussed herein will be referred to as strap 108. In the context of this description and the subsequent claims, strap 108 is a flexible or semi-flexible tether having a primary width 122 and a secondary width 124, wherein the primary width 122 is substantially greater than the secondary width 124, and these widths are perpendicular to the central axis of the tether, and in some embodiments are also perpendicular to each other. Examples include, but are not limited to, nylon webbing, woven fabrics, chains with flat links, strips, ribbons, etc. According to various embodiments, these straps 108 have much higher strength than ropes and are thin in at least one dimension (i.e., secondary width 124). In a particular example, in one embodiment, each strap 108 may have a secondary thickness of 1.5 mm and a primary width of 2 cm. In some embodiments, the secondary width 124 is at least an order of magnitude smaller than the primary width 122.

[0032]

[0038] Another advantage of the strap 108 intended herein is that, in addition to being thin, it folds naturally in one dimension, and its folding / collapse is far more predictable than that of ropes or cables. By adjusting the primary width 122 of the strap 108, the strength can be adjusted without sacrificing stacking height. In some embodiments, the strap 108 can be biased to fold or collapse in a particular direction in its one dimension. The biasing of the strap 108 will be further described with reference to Figure 5 below.

[0033]

[0039] The capture structure 106 comprises multiple discs 110 and straps 108. According to various embodiments, the device 100 utilizes at least three straps 108. In some embodiments, the device may use six straps 108 to suspend the discs 110, allowing three straps 108 to fail or be removed for maintenance without compromising the capture structure 106. One drawback of using straps 108, whose strength is primarily derived from their primary width 122, is that they are more likely to obstruct airflow than cylindrical cables or ropes. This can be mitigated by using different orientations, as described below with respect to Figures 4A-4C.

[0034]

[0040] According to various embodiments, the strap 108 must support the entire weight of the stack of disks 110, and the weight of all the disks 110 quickly increases. Therefore, they need to be robust, and in some embodiments, they need to support a total weight of several tons. On the other hand, the linkage of the disks 110 to the strap 108 does not need to support such a weight. This linkage only supports the weight share of one disk 110. The total weight of a single disk 110 is small, and in some embodiments, it is about 10 kg or less. Therefore, the coupling that holds the disk 110 to the strap 108, or the structure on the strap 108 that supports the disk 110, only needs to withstand a weight of a few kilograms or a force of tens of Newtons. This suggests that actual connectors can be lightweight yet still effective.

[0035]

[0041] The discs 110 are coupled to a strap 108 and spaced apart along the strap 108. This can be achieved in various ways. In some embodiments, including the non-limiting examples shown in Figures 1A–1C, the strap 108 may be coupled to the edge 114 of each disc 110. In the context of this description and the subsequent claims, the edge 114 of the disc 110 refers to the outermost surface or plane around the disc 110. In some embodiments, the strap 108 may be fixedly coupled to the edge 114 of each disc 110 (e.g., by fasteners, adhesives, etc.). In some embodiments, all straps 108 may be coupled to the edge 114 of the disc 110 by the same structure. In some embodiments, each strap 108 may be coupled to the disc 110 individually, while in other embodiments, all straps 108 may be coupled to the disc 110 through the same structure or mechanism.

[0036]

[0042] For example, in one embodiment, each strap 108 of the capture structure 106 may be coupled to the edge 114 of the disk 110 by a belt 116 surrounding the disk 110, so as to press the strap 108 against the edge 114, thereby preventing movement relative to the disk 110 (e.g., friction fit, cinch compression). In the context of this description and the subsequent claims, the belt 116 may be one or more pieces of material, which can conform to the shape or circumference of the disk 110 to such an extent that the belt 116 can exert sufficient force on one or more straps 108 trapped between the belt 116 and the disk 110. In some embodiments, this coupling (and other couplings) may be fixed and permanent. In other embodiments, the couplings may be removable, which may have advantages described in more detail with respect to Figures 3 and 7 below.

[0037]

[0043] As previously mentioned, the capture structure 106 of the collection device 100 can move between the collection configuration 118 shown in Figures 1A and 1B and the release configuration 120 shown in Figure 1C. In the context of this description and the following claims, the collection configuration 118 is when the capture structure 106 extends upward from the release chamber 102 or from any structure adjacent to the release chamber 102. The disk 110 is suspended from the movable part 126 of the device 100 (e.g., the lid 104) by three or more straps 108. While in the collection configuration 118, at least a portion 128 of the capture structure 106 is exposed to an airflow 130, allowing the adsorbent material 112 of the disk 110 to capture carbon dioxide 132.

[0038]

[0044] In the context of this description and the subsequent claims, the release configuration 120 is when a plurality of disks 110 are stacked on top of each other, and the entire stack of disks 110 is entirely within the release chamber 102 for exposure to an adsorbent regeneration system 140, as a result of the release of carbon dioxide 132 adsorbed on the adsorbent material 112. Examples of the adsorbent regeneration system 140 include, but are not limited to, a water source, a steam source, a heater, a vacuum pump, a power supply, etc. According to various embodiments, the released carbon dioxide 132 is removed from the release chamber 102 via a product outlet 136 as a product logistics 138 of concentrated carbon dioxide 132 for storage, purification, pressurization, sequestration, use as a raw material for another process, etc.

[0039]

[0045] The apparatus and methods contemplated herein relate to mounting disks along a strap and manipulating segments of the strap between adjacent pairs of disks 134 (i.e., segments of the strap that need to be moved somewhere when disks are stacked). Specifically, the apparatus and methods contemplated herein manipulate portions of the strap 108 between adjacent disks so as not to interfere with the transition between the collection configuration and the discharge configuration and so as to minimize the volume of the discharge chamber 102. Thus, in various embodiments, it is beneficial to inspect adjacent pairs of disks 110 134.

[0040]

[0046] Figures 2A and 2B are top and cross-sectional views of non-limiting examples of pairs 134 of adjacent disks 110 in the apparatus 100 of Figures 1A-1C when in the discharge configuration 120. While the following description is made in relation to a single pair 134 in various embodiments, it should be noted that this is not a specific pair 134 between disks 110, but rather the following content can be applied to any adjacent pair 134 between multiple disks 110.

[0041]

[0047] As shown in the figure, each adjacent pair 134 comprises a lower disk 200 and an upper disk 202. Both of these disks are coupled to a strap 108, although only two of them are visible in the side section view of Figure 2A. For each strap 108, the portion of the strap 108 between the lower disk 200 and the upper disk 202 is called the connecting segment 204. In other words, the connecting segment 204 of the strap 108 is the portion of the strap 108 that separates the upper disk 202 from the lower disk 200 when the capture structure is in the collection configuration 118 and the disks 110 are fully suspended by the strap 108. For each pair 134, the connecting segment 204 is defined by the upper disk 202 and the lower disk 200.

[0042]

[0048] When conventional methods are used, within adjacent pairs 134, the connecting segment 204 of the strap 108 can cause problems in the operation of the collection device 100. If the strap 108 is too thick, the connecting segment 204 may occupy too much space when the capture structure 106 moves to the release structure 118 as the discs 110 are stacked and collapses. At the very least, this may reduce the efficiency of the device and require a larger release chamber 102, and therefore more resources to apply the adsorbent regeneration system 140 (e.g., more steam to fill the release chamber). In the worst case, the connecting segment 204 may cause a malfunction, preventing the capture structure 106 from fitting into the release chamber 102. According to various embodiments, using conventional methods, the connecting segment 204 collapses in an unpredictable manner, and adapting the device (e.g., the size and shape of the release chamber) to address this unpredictability would introduce inefficiencies into a technology that is already operating on a tight energy and resource budget.

[0043]

[0049] This specification envisions apparatus 100 and methods for operating a connecting segment 204 in a predictable and advantageous manner. According to various embodiments, if the lower disk 200 is not fully supported by the strap 108, the strap 108, more specifically the connecting segment 204, is biased to move toward the discharge topology 206 (i.e., the lower disk 200 is resting on something or being held by something other than the connecting segment 204 on it). In the context of this description and the subsequent claims, the discharge topology 206 is an arrangement of the connecting segment 204 set to a size and position that accommodates a stack of multiple disks 110 throughout the discharge chamber 102. In some embodiments, this allows for efficient accommodation of the stack of disks 110 (e.g., minimizing size without sacrificing fluid communication with the adsorbent material).

[0044]

[0050] The discharge topology 206 can be defined in several different ways. In some embodiments, the discharge topology 206 may be a general one that simply specifies that the connecting segment 204 bends in a particular direction. In other embodiments, the discharge topology 206 may be more specific, defining the particular shape that the connecting segment 204 takes as the capture structure 106 moves toward the discharge configuration 120. In yet another embodiment, the discharge topology 206 may be defined as a volume in which the connecting segment 206 is constrained to fit inside, but which may exhibit different shapes within that volume. These variations may be caused by changes in the state of the capture structure 106 as it moves between configurations. As a particular example, if the capture structure 106 begins to twist slightly due to the airflow 130 as it descends into the discharge chamber 102, the connecting segment 204 of the strap 108 may be in a slightly different position, but may be biased to ultimately result in a predictable volume despite such variations, so that the device 100 can be designed to operate consistently and efficiently even in environments where such variations are common and vary. The biasing of the strap 108 will be described in more detail below with reference to Figure 5.

[0045]

[0051] In some embodiments, the emission topology 206 may be such that the connecting segment 204 folds to form a folding edge 210 (i.e., a "hinge" of the fold). In embodiments in which the emission topology 206 includes a single fold (i.e., a single folding edge 210), the connecting segment 204 does not occupy much space, particularly because the secondary width 124 of the strap 108 can be very small. In some embodiments, the emission topology 206 can further define where the folding edge 210 is located relative to the disk 110. For example, in the non-limiting example shown in Figures 2A and 2B, the folding edge 210 is located in the gap 212 or empty space between the stack of disks 110 and the wall of the emission chamber 102. This emission topology 206 has advantages and disadvantages, as with many other topologies. Advantageously, most, if not all, of the connecting segment 204 is located outside the space between the upper disk 202 and the lower disk 200, thereby facilitating fluid contact between the adsorbent material 112 of these disks 110 and the inside of the discharge chamber 102 during regeneration. However, as illustrated, folding into the gap 212 requires the use of a larger discharge chamber 102, which may increase the volume of some of the regeneration resources required (e.g., water, steam, heat, pump, etc.), and therefore, as described above, reduces the overall efficiency. Other positions of the folding edge 210 are described below in relation to Figures 3A and 3B, as well as Figures 4A and 4B.

[0046]

[0052] The gap between the upper disk 202 and the lower disk 200 shown in the non-limiting example of Figure 2A is exaggerated for visual clarity. In some embodiments, the gap 208 between the upper disk 202 and the lower disk 200 may be small compared to other dimensions of the capture structure 106. In the context of this description and the subsequent claims, the gap 208 is the maximum vertical distance between adjacent pairs of lower disks 200 and upper disks 202 when the capture structure 106 is in the release configuration 120. In some embodiments, the gap 208 between adjacent disks 110 may be no more than three times the secondary width 124. In other embodiments, the gap 208 may be slightly larger than twice the secondary width 124. In yet another embodiment, the gap 208 between adjacent disks 110 may be about half the thickness 214 of the disk 110. In yet another embodiment, the gap 208 between adjacent disks 110 may be about the thickness 214 of the disk 110.

[0047]

[0053] Figures 3A and 3B are side and top cross-sectional views, respectively, of a non-limiting example of a pair of adjacent disks 110 134 from another embodiment of the passive carbon dioxide collector 100 in the emission configuration 120. In some embodiments, such as the non-limiting example shown in the previous figure, the strap 108 may be coupled to the disk along its outermost edge 114. In other embodiments, the strap 108 may pass through the disk 110. Coupling the strap 108 to the disk 110 by passing the strap 108 through the opening 300 may be advantageous because it can provide a strong bond that does not add as much weight or volume to the disk as external coupling as shown in the previous figure. External coupling almost always requires adding material (e.g., belt 116, adhesive, fasteners, etc.) to the disk 110, whereas coupling with an opening 300 instead involves removing mass from the disk 110 to form the opening 300.

[0048]

[0054] According to various embodiments, including non-limiting examples as shown in Figures 3A and 3B, each disk 110 may have multiple openings 300 through the disk 110, one for each strap 108. According to various embodiments, the openings 300 may have a variety of shapes, including but not limited to circular, rectangular, and trapezoidal shapes.

[0049]

[0055] Each strap 108 passes through a different opening 300 to the disk 110 and is then coupled to the disk 110 in a removable or otherwise manner near the opening 300. In the context of this description and the subsequent claims, proximity to the opening 300 means, with respect to coupling to the straps 108, that the coupling between the disk 110 and the straps 108 occurs either inside the opening 300 or via something that is in direct contact with the surface of the disk surrounding the opening 300.

[0050]

[0056] For example, in the non-limiting examples of adjacent pairs 134 shown in Figures 3A and 3B, each disc 110 is removably coupled to six straps 108 adjacent to six openings 300. As shown in Figure 3A, according to some embodiments, the discs 110 are coupled to the straps 108 via stoppers 302 that are removably coupled to the straps 108 below the discs 110. The stoppers 302 are sized and / or shaped such that they are not large enough to pass through the openings 300 through which the straps 108 pass, allowing the straps 108 to be used to lift the discs 110 from the release configuration 120.

[0051]

[0057] In some embodiments, the disc 110 may be fixedly coupled to the strap 108. In other embodiments, the disc 110 may be detachably coupled to the strap 108, which allows for adjustment of the location where the disc 110 is mounted along the strap 108. In some embodiments, this may be advantageous because the strap 108 may be made of a material that changes over time due to exposure. As a specific example, in a device 100 where one side is exposed to more sunlight than the other side, the strap 108 receiving more solar heat may stretch over time. The disc 110 and the ground, which started substantially parallel to each other, will eventually begin to tilt. This may increase the force applied to the capture structure 106 by gusts of wind, potentially causing further problems beyond a decrease in effectiveness. If the disc 110 can be detached from one or more straps 108 and then reattached, such a situation can be rectified before it fails.

[0052]

[0058] Another example of a removable coupling is the use of a bridge-like structure spanning between the openings 300, holding the disc 110 on the "crossbars" of a plurality of ladders made of a pair of straps 108. Yet another example of a removable coupling may be a belt buckle that latches onto the straps 108, or something similar to a hole in the straps 108. Those skilled in the art will recognize that many other methods exist for removablely coupling the disc 110 to a plurality of straps 108, and that other methods known in the art can be adapted for use in the disc-based collection device 100.

[0053]

[0059] As mentioned above, many emission topologies 206 have both advantages and disadvantages. The emission topology 206 shown in the previous figure, in which the folded edge 210 is located in the gap 212 between the disk 110 and the inner wall of the emission chamber 102, has the disadvantage of requiring a larger emission chamber 102 than would otherwise be necessary. According to various embodiments, an emission topology 206 that solves this problem (however, a new problem arises that happens to be solved by topology 206 in the previous figure) is in which each connecting segment 204 has a single fold, and the folded edge 210 is sandwiched between the upper disk 202 and the lower disk 200. By folding the connecting segments 204 inward, the size of the gap 212 can be reduced, thereby increasing the efficiency of the device 100.

[0054]

[0060] However, according to various embodiments, the release topology 206 in which the folded edge 210 is sandwiched between the upper disk 202 and the lower disk 200, or any other arrangement in which the strap 108 is almost trapped between the disks 110 when in the release configuration 120, may require cutting out the surface of the disks 110 to form a groove 304 of a size and position that accepts (or at least partially accepts) the connecting segment 204, thereby reducing the height of the stacked disks 110. This may result in a very small gap 208, but the drawback is that the groove 304 may reduce the surface area of ​​the adsorption material 112 on the disks 110. In some embodiments, the groove 304 may be on one side of each disk 110. On the other hand, in other embodiments, both sides of the disk 110 may have grooves 304 aligned to form a pocket for the connecting segment 204 when the capture structure 106 is in the release configuration 120. In a particular example, in one embodiment, the depth of the groove 304 may be 0.3 cm.

[0055]

[0061] As described above, in some embodiments, the strap 108 may always be biased to fold in a particular direction. For example, the strap 108 in Figures 2A and 2B can always be biased to fold outwards. In other embodiments, the strap 108 may fold in either direction. In other words, in some embodiments, the discharge topology 206 may be large enough to enclose the connecting segment 204 folded in either direction. For example, in one embodiment, the device 100 may have a larger discharge chamber 102 required for folding outwards in Figures 2A and 2B, in addition to the groove 304 required for folding inwards in Figures 3A and 3B. Thus, the strap 108 can be folded in either direction without interfering with the operation of the device 100.

[0056]

[0062] Figures 4A, 4B, and 4C are top views of non-limiting examples of the lower disk 200 of an adjacent disk pair 134 according to different embodiments, each comprising a strap 108 having a different orientation 400. In the context of this description and the following claims, the orientation 400 of the strap 108 refers to its angle with respect to the disk 110 at the point where the disk 110 and the strap 108 intersect (i.e., an opening 300, edge 114, etc.). More precisely, the orientation 400 of the strap 108 is the angle formed between the primary width 122 of the strap 108 and the radius 402 of the disk 110 that bisects the primary width 122. In the context of this description and the following claims, the radius 402 of the disk 110 is a vector extending outward from the centroid 408 or geometric center of the disk 110.

[0057]

[0063] According to various embodiments, the strap 108 can be coupled to the disk 110 in various orientations 400. In some embodiments, including the non-limiting example shown in Figure 4A, the strap 108 can pass through or be coupled to the disk 110 in a tangential aspect 404. In the context of this description and the subsequent claims, the tangential aspect 404 is when the orientation 400 of the primary width 122 is closer to perpendicular to the radius 402 that bisects the primary width 112 than is parallel to the radius 402. In some embodiments, the tangential aspect 404 may refer to a primary width 122 having an orientation 400 within 10 degrees from perpendicular to the radius 402. In other embodiments, the tangential aspect 404 may refer to a primary width 122 having an orientation 400 within 15 degrees from perpendicular to the radius 402.

[0058]

[0064] Passing the strap 108 over the disk 110 in a tangential manner 404 may be advantageous because it can prevent the trapping structure 106 from twisting or rotating in the airflow 130. However, the tangential manner 404 can also prevent some of the airflow 130 from entering the space between the disks 110, as the strap 108 can act as a series of narrow walls around the disk 110.

[0059]

[0065] In some embodiments, including the non-limiting examples shown in Figure 4B, the strap 108 may pass through or be coupled to the disk 110 in a radial aspect 406. In the context of this description and the following claims, a radial aspect 406 is when the orientation 400 of the primary width 122 is closer to parallel to the radius 402 that bisects the primary width 112 than is perpendicular to the radius 402 that bisects the primary width 112. In some embodiments, a radial aspect 404 may refer to a primary width 122 having an orientation 400 within 10 degrees of parallel to the radius 402. In other embodiments, a radial aspect 404 may refer to a primary width 122 having an orientation 400 within 15 degrees of parallel to the radius 402.

[0060]

[0066] Passing the strap 108 through the disc 110 in a radial configuration 406 may be advantageous because it may obstruct the airflow 130 as little as the tangential configuration 404. However, the radial configuration 406 may cause the airflow 130 to rotate the capture structure 106, causing the connecting segment 204 to function as a small rotor blade. In some situations, this rotation may be beneficial. This action helps the capture structure 106 to rapidly release moisture after a regeneration cycle in the discharge chamber 102, accelerating the cycle of the moisture swing-based collector 100. However, unless rotational or torsional forces are anticipated and taken into account, such strains may cause wear on the strap 108 or the strap's coupling to the moving part 126, ultimately leading to failure of the device 100.

[0061]

[0067] In some embodiments, all of the straps 108 may have the same orientation 400. In other embodiments, the straps 108 may have two, three, or more different orientations 400. In some cases, it may be advantageous to have different strap orientations 400 within the same capture structure 106. In some embodiments, including the non-limiting example shown in Figure 4C, different orientations 400 can be used to break the rotational symmetry of the capture structure 106 with respect to the vertical central axis of the capture structure 106 passing through the center of gravity 408 of the disk 110, thereby preventing rotation caused by the airflow 130. In some embodiments, the straps 108 may use a variety of orientations 400 (e.g., tangential, radial, etc.) to achieve a balance of the advantages and disadvantages discussed herein. Ultimately, the best orientation 400 depends on many considerations, including, but not limited to, the type of adsorption material 112 used and the energy cost of regeneration per unit volume of the release chamber 102.

[0062]

[0068] Figure 5 is a side cross-sectional view of some non-limiting examples of the connecting segments 204 of the strap 108. As previously mentioned, the strap 108 (or at least the connecting segments 204 of the strap 108) is biased to move toward the emission topology 206. In some embodiments, biasing can be achieved through the structure of the strap 108 (e.g., thickening one side of the wave of the webbing strap). In other embodiments, material can be added to the uniform strap 500 to break symmetry and / or facilitate folding in a desired direction and / or at a desired point, thereby entering a desired emission topology 206. For example, in some embodiments, including the non-limiting examples shown in Figure 5, the strap 108 comprises a uniform strap 500, and each connecting segment 204 of the strap 108 comprises at least one biasing strap 502 coupled to the uniform strap 500.

[0063]

[0069] In some embodiments, the strap 108 may comprise a uniform strap 500 coupled to a single biasing strap 502 over its entire length. Optionally, in some embodiments, the biasing strap 502 may be composed of a slightly deformed elastic material 504, so that the side of the strap 108 having the biasing strap 502 tends to contract, biasing the strap 108, or the unrestrained portion of the strap 108 (i.e., the connecting segment 204), to bend toward the biasing strap 502 to reduce its deformation. The elastic material 504 may be an elastomer or other material having elastic properties and suitable for coupling to the uniform strap 500.

[0064]

[0070] In other embodiments, including the non-limiting example shown in Figure 5, the strap 108 may include a uniform strap 500, and each connecting segment 204 includes two biasing straps 502 coupled to the uniform strap 500, with the two biasing straps 502 separated by a break 506 (for each connecting segment 204). Similar to embodiments where a single biasing strap 502 extends along the length of the uniform strap 500, the biasing strap 502 separated by the break 506 may also be composed of a slightly strained elastic material 504, which causes the connecting segment 204 to bend toward the biasing strap 502. However, the folded edge 114 of the resulting emission topology 206 will, as expected, be where the break 506 is located, since there is no interfering biasing strap 502. Still other embodiments may use coatings, sleeves, recesses, etc., to bias the strap 108 to fold into a desired emission topology 206 or otherwise collapse.

[0065]

[0071] It should be noted that in embodiments using the opening 300 (e.g., embodiments in Figures 3A and 3B), and similarly in embodiments where the strap 108 is joined along the outer edge 114 by friction (e.g., embodiments in Figures 2A and 2B), the shape of the strap 108 may be determined by, or at least influenced by, the shape of the surface of the disc 110 to which it is joined (e.g., the shape of the opening 300, the shape of the edge 114, etc.). Changing the shape of the strap 108 beyond a flat surface may help to facilitate folding in a particular direction or inhibit folding in another direction, similar to the curvature of a metal measuring tape that allows it to withstand buckling under its own weight when stretched.

[0066]

[0072] In some embodiments, the strap 108 may be directly exposed to the disk 110, the binding, and / or the elements. In other embodiments, including non-limiting examples shown in Figures 6A and 6B, the strap 108 may be enclosed within a sock or sleeve 600 extending over the length of the strap 108. Figures 6A and 6B are cross-sectional views of non-limiting examples of the capture structure 106 in a collection 118 configuration and a release 120 configuration, respectively. As shown, each strap 108 is enclosed within a sleeve 600. In some embodiments, the sleeve 600 may be made of a stretchable elastic material 504. In other embodiments, the sleeve 600 may be made of other materials. For example, in one embodiment, the sleeve 600 may be made of a material resistant to UV radiation, which may help extend the lifespan of the strap 108 without sacrificing the strength-to-size ratio of the strap 108. Those skilled in the art will recognize that the sleeve 600 may be made of other materials that better adapt the device 100 to a particular environment (for example, a caustic environment in which the collection device 100 is used to capture carbon dioxide emitted from an industrial process).

[0067]

[0073] In some embodiments, the sleeve 600 is composed of an elastic material 504, and the sleeve 600 may be biased to contract from an extended state 602 (i.e., Figure 6A) corresponding to the capture structure 106 being in a collection configuration 118 to a relaxed state 604 (i.e., Figure 6B) corresponding to the capture structure 106 being in a release configuration 120. In some of these embodiments, the sleeved strap passes through the disk 110 through an opening 300 in the disk 110. According to various embodiments, the opening 300 in the stacked disks 110 can be aligned to define a passage 606 extending to the height of the stack. According to various embodiments, including a non-limiting example shown in Figure 6B, the relaxed state 604 of the sleeve 600 is contained within a passage 606 bounded by the opening 300 through which the strap 108 passes, and as a result, when the capture structure 106 is in a release configuration 120, the release topology 206 of the strap 108 includes a connecting segment 204 housed within the passage 606 by the sleeve 600. Such an emission topology 206 avoids the problems introduced by the outward and inward folding embodiments, as discussed above. It does not require additional space in the gap 212 that increases the size of the emission chamber 102, nor does it require grooves 304 in the disk 110 that reduce the surface area of ​​the adsorbent material 112.

[0068]

[0074] The intended sleeve 600 offers several advantages. Using the sleeve 600, the resulting vertical channel and the straps 108 within it can be fully protected by using a thin fibrous material that can be stretched to accommodate an extended version of the disc 110 stack. The sleeve 600 can protect the straps 108 from UV, moisture, or other elements that could compromise the integrity of the straps 108. Furthermore, the sleeve 600 will prevent debris from entering the channel. In some embodiments, the sleeve 600 can be self-supporting like a sock, while in other embodiments, it may have an embedded coil to add some rigidity.

[0069]

[0075] Figures 7A and 7B show cross-sectional views of non-limiting examples of a removable coupling located within the opening 300 in the engaged and disengaged states, respectively. Specifically, this removable coupling is a self-tightening clamp 700. As shown, the strap 108 passes between two rotating wedges 702 having textured surfaces that grip the strap 108. When the texture engages with the strap 108, the wedges 702 rotate inward to clamp the strap 108. See Figure 7A. The greater the weight of the disc 110 that pushes down the clamp 700, the tighter the clamp 700 grips the strap 108. According to various embodiments, the clamp 700 can be disengaged by lifting the disc 110 (i.e., Figure 7B) and rotating the wedges 702 in the direction of the movement of the strap 108 relative to the disc 110 until the strap 108 is no longer clamped, and the strap 108 can slide freely as long as the wedges 702 remain open. This allows for adjustment of the height of the disc 110 on the strap 108. When the weight is removed, the clamp 700 can slide into a more suitable position and be secured there again. This is similar to the clamps used on cargo straps, but can be much lighter as it only needs to hold the weight of a single disc 110.
