[0007] Sorption filter for use in a sorption plant

[0008] The invention relates to a sorption filter for sorbing and / or desorbing at least one substance for use in a sorption system, comprising several filter segments, each comprising at least one sorption layer containing sorption material and at least one support layer for the sorption material, and at least one connecting segment that connects two filter segments together.

[0009] The invention further relates to a connecting segment for a sorption filter having several filter segments, with a first connecting area which can be connected to a first filter segment of the sorption filter, and a second connecting area which can be connected to a second filter segment of the sorption filter.

[0010] Furthermore, the invention relates to a filter segment for a sorption filter, comprising several superimposed layered composites extending in a longitudinal direction, each comprising at least one sorption layer containing sorption material and at least one carrier layer for the sorption material.

[0011] Furthermore, the invention relates to a sorption system for sorbing and / or desorbing at least one substance, comprising at least one sorption filter and a drive device for moving the sorption filter within the sorption system. The invention further relates to a method for operating a sorption system, comprising the steps of: sorbing at least one substance in and / or on one or more filter segments of a sorption filter of the sorption system, moving at least one filter segment of the sorption filter into at least one treatment area of ​​the sorption system, and desorbing the at least one substance from and / or from one or more filter segments of the sorption filter in the at least one treatment area.

[0012] Furthermore, the invention relates to a manufacturing process for producing a sorption filter, comprising the steps of: producing or providing several filter segments, each comprising at least one sorption layer containing at least one sorption material and at least one support layer for the sorption material, and producing or providing at least one connecting segment.

[0013] Sorption filters, particularly those designed as belt absorbers, are known in the prior art and can, for example, be configured as continuous filter belts. Such sorption filters can be used to implement sorption and / or desorption processes, for example, to sorb and / or desorb greenhouse gases such as carbon dioxide.

[0014] In known sorption filters, the sorption material is typically located within a material holding area of ​​the sorption filter, for example, between two layers of the filter material. The sorption material is usually granular or powdery. Although the sorption material is enclosed within the material holding area, it can move freely within this area. Such a sorption filter is known, for example, from US Patent 7,377,966 B2.

[0015] In sorption systems, a sorption filter is often moved along a predetermined filter path and deflected by deflection elements, particularly deflection rollers. This deflection exerts mechanical forces on the sorption filter, causing the sorption material within it to move and / or detach from the filter. Consequently, sorption filters known in the prior art are subject to high wear, particularly due to their insufficient mechanical strength. Furthermore, the movement of the sorption material within the material holding area can lead to a local reduction or even a local interruption of the sorption layer, which can severely impair the sorption properties of the filter.

[0016] In sorption systems, sections of the sorption filter are typically moved into a treatment chamber before the chamber is sealed gas-tight from the environment. Since the sorption filter extends into and out of the treatment chamber, sealing problems have arisen, particularly at the interfaces. Furthermore, opening and closing the treatment chamber should ideally be abrasion-free or abrasion-free to prevent the sealing process from impacting the filter's service life. A gas-tight seal of the treatment chamber significantly increases energy efficiency in both the sorption and desorption processes. It also prevents parasitic leakage currents of fluids, substances, or energy, such as those resulting from heat or cold equalization or pressure equalization.

[0017] The object underlying the invention is therefore to enable low-abrasion or abrasion-free operation of a sorption system in which one or more sections of the sorption filter extend at least temporarily through a treatment area to be sealed.

[0018] The problem is solved by a sorption filter of the type mentioned above, wherein the sorption material is immobilized by means of at least one fixing agent and fixed to the at least one support layer. The sorption material is, for example, a sensitive, porous and / or granular sorbent.

[0019] During sorption, at least one substance accumulates in and / or on at least one sorption layer. During desorption, the at least one substance accumulated in the at least one sorption layer is released from and / or on the at least one sorption layer. During sorption, the at least one substance is filtered from the environment. During desorption, the at least one substance is released into the environment or into at least one space. The at least one space can be a treatment area, for example, a vacuum chamber or a reservoir, for example, for concentrated, at least temporary, storage and / or transport.

[0020] The at least one substance may be a contaminant. The at least one substance may be present in the environment. The at least one substance may be gaseous and / or liquid. The at least one substance may exist in different states of matter under different conditions, particularly at different temperatures and / or pressures. The at least one substance may be gaseous, particularly under atmospheric conditions. Atmospheric conditions include an air temperature range of -20 to 60 °C and an air pressure range of 0.8 to 1.1 bar. The at least one substance may include water, particularly water vapor. The at least one substance may be a trace gas. Trace gases include, for example, carbon dioxide, carbon monoxide, hydrogen, methane, ammonia, nitrogen oxides, fluorinated gases, hydrogen sulfide, sulfur dioxide, noble gases, aromatic hydrocarbons, and / or alkanes.The at least one substance may comprise aerosols, which may be present as a pure substance and / or contain dissolved and / or solid substances. The at least one substance may comprise per- and / or polyfluorinated chemicals. The at least one substance may comprise greenhouse gases. These greenhouse gases include, for example, carbon dioxide, methane, nitrous oxide, nitrogen trifluoride, and / or fluorinated greenhouse gases, in particular fluorocarbons, perfluorinated hydrocarbons, and / or sulfur hexafluoride. The at least one substance may comprise chlorofluorocarbons (CFCs). The sorption filter can reduce the concentration of the at least one substance in the ambient air. The at least one substance may be or contain a finely dispersed condensate, for example, in droplet form.

[0021] The multiple filter segments can each be partially saturated with the at least one substance, particularly during a sorption or desorption process. The multiple filter segments can each be completely or partially saturated with the at least one substance, particularly after a completed adsorption process. Alternatively, the multiple filter segments can each be completely or partially saturated during a sorption process. The multiple filter segments can each be largely or completely unsaturated, i.e., essentially free, of the at least one substance, particularly after a completed desorption process. For example, a first of the multiple filter segments can be completely saturated with the at least one substance, while a second of the multiple filter segments is simultaneously partially saturated with the at least one substance.Alternatively, the second or additionally a third of the several filter segments can be completely unsaturated, i.e., essentially free of at least one substance.

[0022] The sorption material enables and / or accelerates the sorption, adsorption, and / or absorption of at least one substance on and / or in the at least one sorption layer of the multiple filter segments. The sorption material can be an adsorbent and / or an absorber, in particular a carrier material equipped with an absorber, especially an adsorbent. The sorption material can be free-flowing, granular, or powdery. The particle size is preferably in the range of 10 nm to 5 mm, particularly preferably in the range of 0.1 to 3 mm.The sorption material can comprise ion exchange resins, in particular Lewatit VP OC 1065, porous polymers, metal-organic frameworks (MOFs), in particular amine-based MOFs, covalent-organic frameworks (COFs), zeolitic imidazolate frameworks (ZIFs), zeolites, clay minerals, aluminum oxide, silica gel, carbon molecular sieves, carbon nanotubes, graphite, graphene, cyclodextrins, cucurbiturils, cellulose, alginates, or activated carbon, as well as their at least partially chemically modified and / or impregnated variants. The sorption material can further be formed as a monolith, foam structure, gyroid, aerogel, geometric lattice, nonwoven, or honeycomb structure, with the active functionality being concentrated particularly in the surface area, which can be applied in particular by coating processes, for example, washcoat coatings or adhesive application using fixatives. Sorption materials of the same size orDifferent pore sizes can be used in combination, especially in ascending or descending pore size in a hierarchical arrangement.

[0023] The at least one support layer of a filter segment carries the at least one sorption layer of the filter segment. The at least one sorption layer of the filter segment can be located on the top or bottom of the support layer of the filter segment.

[0024] At least one connecting segment can connect two filter segments to each other in a force-fit, form-fit and / or material-fit manner.

[0025] The at least one fixing agent is located between the at least one support layer of the filter segment and the at least one sorption layer of the filter segment. Consequently, the fixing agent is located on the side of the at least one support layer of the filter segment facing the at least one sorption layer. Because the sorption material is immobilized by the fixing agent and fixed to the at least one support layer, relative movement of the sorption material, or of the at least one sorption layer encompassing the sorption material, to the support layer of the filter segment is prevented. Furthermore, fixing the sorption material with the fixing agent prevents abrasion of the sorption material. The fixing agent can be arranged as a fixing layer on the at least one support layer. The fixing agent can be distributed over the entire surface or in specific areas on or around the at least one support layer.By immobilizing the sorbent material with the fixative and fixing it to the at least one support layer, the sorbent material adheres to the at least one support layer. The fixative can increase the friction, in particular static friction, between the at least one support layer and the sorbent material, or between the at least one sorbent layer encompassing the sorbent material. The fixative can comprise adhesives, in particular sprayable hot melt adhesives with a high crystalline content, specifically selected from the group of reactive one-component polyurethane (PUR) hot melt adhesives (polyol and isocyanate from one feed), reactive two-component PUR adhesives (polyol and isocyanate from two feeds), or polyolefins.The fixing agent may include free-flowing, powdered and / or granular polymers, in particular ultra-high molecular weight polyethylene (IIHMPE), polyethylene, high-density polyethylene (HDPE), ultra-high molecular weight polypropylene (IIHMPP), polypropylene, polyolefins, polyvinylene difluoride (PVDF), polyamides, polyesters, ethylene vinyl acetate, acrylic acid esters, styrene-butadiene copolymer and other copolymers.

[0026] The multiple filter segments can each comprise at least one additional layer. This additional layer can be in contact with the support layer of at least one of the multiple filter segments. The additional layer can be in contact with the sorption layer of at least one of the multiple filter segments. The additional layer can be located between a support layer and a sorption layer. The additional layer can provide improved lubricity, stability, and / or spacing, and / or incorporate particle filtration properties.

[0027] The multiple filter segments can each include a cover layer. At least one cover layer can be in contact with an outer support layer and / or a sorption layer. The outer support layer is located on the side of the respective filter segment facing away from the other, i.e., inner, support and sorption layers of that filter segment. The cover layer can cover the outer support layer. At least one cover layer can be in contact with an outer sorption layer. The outer sorption layer is located on the side of the respective filter segment facing away from the other, i.e., inner, support and sorption layers of that filter segment. The cover layer can cover the outer sorption layer.

[0028] In a preferred embodiment of the sorption filter according to the invention, the filter segments and / or the at least one connecting segment and / or components of the filter segments and / or the at least one connecting segment are replaceable without damage. For example, the at least one sorption layer and / or the at least one support layer are replaceable without damage. Consequently, one or more worn or damaged segments of the sorption filter can be replaced, thus ensuring the functionality of the sorption filter, particularly over a longer service life.

[0029] Furthermore, a sorption filter according to the invention is advantageous in which the at least one support layer is gas-permeable, in particular air-permeable. The at least one support layer can have a comparatively high air permeability. Because the at least one support layer is air-permeable, the air containing the at least one substance can flow through it. Consequently, the adsorption of the at least one substance is accelerated, since the accumulation of the at least one substance in and / or on the at least one sorption layer is accelerated. In addition, the desorption of the at least one substance is accelerated, since the release of the at least one substance from and / or out of the at least one sorption layer is accelerated.Because the at least one support layer is air-permeable, there is an increased exchange of the at least one substance between the at least one sorption layer and the air flowing through the at least one support layer. The at least one support layer can have a porous structure, for example, a foam structure or a nonwoven fabric. The porous structure of the at least one support layer can enable or improve its air permeability. The at least one support layer can comprise a textile, in particular an air-permeable textile. The textile can comprise a woven fabric, non-woven fabric, and / or knitted fabric. The textile can comprise natural fibers and / or synthetic fibers. The textile can comprise nonwoven fabric, nonwoven material, felt, sewn knit fabric, braid, and / or knitted fabric. The textile can comprise polyester.

[0030] In another preferred embodiment of the sorption filter according to the invention, the at least one connecting segment has a different segment height and / or a shorter segment length than the filter segments. Because the at least one connecting segment has a shorter segment height than the filter segments, it is thinner. The at least one connecting segment can also have a shorter segment length than the filter segments. Consequently, the at least one connecting segment can be shorter than the filter segments. Due to its shorter segment height and / or length, the at least one connecting segment enables low-abrasion or abrasion-free mechanical conveying of the sorption filter, low-abrasion or abrasion-free sealing of treatment areas, and low-abrasion or abrasion-free deflection of the sorption filter, for example, around deflection rollers.The at least one connecting segment can include devices and / or recesses that facilitate the conveyance of the sorption filter and / or the sealing of at least two adjacent filter segments and / or the deflection of the sorption filter. In an advantageous embodiment, the at least one connecting segment has a particularly small volume. The at least one connecting segment can be taller than the filter segment, so that when the sorption filter is deflected, the filter segment comes into less or no contact with the at least one deflection device, thereby reducing or completely preventing mechanical stress on the filter segments and resulting in reduced abrasion or mechanical damage. The at least one taller connecting segment can be compressible and possess resilience.In an advantageous embodiment, the resilience is so high that the connecting segments return completely or almost completely to their uncompressed state. The at least one connecting segment can be flatter than the filter segment, so that the sorption filter consists predominantly of filter segments, thus minimizing dead volume in the treatment chambers. Alternatively, the at least one connecting segment can be shorter than the filter segment, so that the sorption filter consists predominantly of filter segments. In an advantageous embodiment, the at least one connecting segment has a particularly low heat capacity, resulting in minimal heat input into the at least one treatment area. The at least one connecting segment can be made of a foam material, for example, a closed- or open-cell polyurethane foam, or a plastic material with a softening point above the temperatures of the treatment areas.

[0031] Furthermore, a sorption filter according to the invention is preferred in which the filter segments each have several layered assemblies that are movable relative to one another. The several layered assemblies that are movable relative to one another are in contact with each other. The several layered assemblies that are movable relative to one another

[0032] Layered structures slide against each other during relative movement. The multiple

[0033] Filter segments can, for example, each have two, three, four, or more than four movable layer assemblies. The multiple movable layer assemblies can each have an identical layer structure, identical layer thicknesses, and / or an identical [feature / component].

[0034] exhibit layered material. The several movable relative to each other

[0035] Layered composites can contain multiple sorption materials in one

[0036] The layered composite and / or, particularly preferably, each layered composite contains a sorption material. The multiple layered composites, which are movable relative to each other, can have different layer thicknesses and / or

[0037] The layered structures can have alternating layer thicknesses and / or layer lengths. Alternatively, the layered structures can be designed so that the filter segment has a trapezoidal shape. The multiple sorption materials contained within a layered structure and / or a filter segment can sorb multiple substances, with each sorption material predominantly absorbing at least one substance. At least one layered structure can consist of an open-pore PU foam, monolith, gyroid, aerogel, geometric grid, nonwoven fabric, or honeycomb structure equipped with sorption material. The at least one filter segment can be composed of several identical or different layered structures. The multiple filter segments can be composed of differing layered structures and / or layered structure arrangements and / or at least partially different sorption materials.

[0038] In a further preferred embodiment of the sorption filter according to the invention, the filter segments and the at least one connecting segment form a longitudinally extending filter belt, wherein the layered composites of the respective filter segments are movable relative to one another in the longitudinal direction. The multiple layered composites movable relative to one another each have a smooth surface. Consequently, the surfaces of the multiple layered composites movable relative to one another exhibit comparatively low sliding friction and / or static friction. The surfaces of the multiple layered composites movable relative to one another can each be designed as a sliding layer. The filter belt can comprise multiple filter segments and multiple connecting segments and can be designed as a circumferential filter belt. The filter belt can extend along a closed filter path or form a closed filter path.Thus, the multiple filter segments and connecting segments can be arranged in a ring or in a row. If the filter belt is designed as a circumferential filter belt, the multiple filter segments and connecting segments form a circumferential, or closed, filter belt. The filter belt can have multiple filter segments and at least one connecting segment and can be designed as a longitudinally movable filter belt, with two ends of the filter belt, each formed by a connecting segment or filter segment. The filter belt can be at least partially wound up and / or erected, resulting in a compacted form of at least two filter segments. The winding up and / or erection of the at least two filter segments can be carried out in both the circumferential filter belt and the filter belt with open ends.The winding and / or erection of the at least two filter segments takes place in at least one adsorption zone and / or at least one desorption zone. The filter belt can be open, closed, or closable.

[0039] Furthermore, a sorption filter according to the invention is advantageous in which the layered composites each comprise at least one sorption layer and at least one support layer. Because the multiple layered composites each comprise at least one sorption layer and at least one support layer, for example, the at least one sorption layer and at least one support layer of a first layered composite and the at least one sorption layer and at least one support layer of a second layered composite are movable relative to each other. The multiple layered composites are preferably arranged such that the at least one sorption layer of one layered composite is in contact with the support layer of an adjacent layered composite.

[0040] In another preferred embodiment of the sorption filter according to the invention, the filter segments each have at least one retaining element that holds together the multiple layered composites of the respective filter segments. Because the at least one retaining element holds together multiple layered composites, it is preferably ensured that the multiple layered composites are in contact with one another. The layered composites held together by the retaining element can move longitudinally relative to one another. The retaining element can partially surround the multiple layered composites. The at least one connecting segment and / or retaining element can consist of polyester, polyamides, polyurethanes, rubber, natural rubber, synthetic rubber, or renewable raw materials, such as products from plants, fungi, animals, or products manufactured using biotechnological processes.At least one connecting segment can consist of the same material as the retaining element, preferably in a more compact or airtight form than the retaining element of the filter segment. In one variant, the retaining element can extend continuously from the filter segment to the adjacent connecting segments. The retaining element can be formed by the support structure.

[0041] Furthermore, a sorption filter according to the invention is advantageous in which the retaining element is designed as a sheath that surrounds the at least one sorption layer and the at least one support layer. Surrounding the at least one sorption layer and the at least one support layer can mean that at least one further layer, for example a cover layer or additional layer, is located between the at least one sorption layer or the at least one support layer and the sheath. The sheath partially or completely surrounds the at least one sorption layer and the at least one support layer. The sheath holds the at least one sorption layer and the at least one support layer together. The sheath can be air-permeable. The sheath can be stretchable and / or flexible. The sheath can comprise a textile, in particular an air-permeable textile.The textile can be a woven fabric, non-woven fabric, and / or knitted fabric. The textile can contain natural fibers and / or synthetic fibers. The textile can contain nonwoven fabric, fleece, felt, sewn knit, braid, and / or knitted fabric. The textile can contain polyester. The coating can reduce or completely prevent damage to components and / or abrasion caused by detaching sorbent material. At least one connecting segment can be part of the coating. Connecting sections of the coating can be joined to one another, for example, by sewing, thermally bonding, welding, gluing, twisting, or punching. In the connecting sections, the coating constitutes at least one connecting segment.

[0042] The sorption filter according to the invention is further advantageously developed in that the at least one connecting segment for gas-tight enclosure of at least one filter segment in at least one treatment area, in particular in at least one sorption area, preferably in at least one desorption area, of the sorption system is gas-tight in at least one sealing direction. The at least one treatment area can be or comprise a vacuum chamber. Conditions in the treatment area can differ from atmospheric conditions. For example, a comparatively low air pressure can prevail in the sorption area. A comparatively high temperature can prevail in the treatment area. The at least one treatment area can represent one or more closed systems or compartments. A thermodynamic equilibrium can prevail in the one or more treatment areas.The thermodynamic equilibrium can be shifted within the treatment area. Desorption of at least one substance from the sorption filter can be enabled within the treatment area. Desorption of at least one substance from the sorption filter can be promoted or accelerated within the treatment area. The treatment area can be designed to minimize residual air around the filter segment. The moisture content of at least one filter segment can be reduced within the treatment area. The at least one connecting segment can be comparatively more gas-tight and / or thermally insulating relative to the filter segment.

[0043] In a further preferred embodiment of the sorption filter according to the invention, the at least one connecting segment is deformable, in particular elastically deformable. The at least one connecting segment can be flexible in one or more directions. The at least one connecting segment can be compressed and / or squashed without damage. The at least one connecting segment can be stretched and / or elongated without damage. If the at least one connecting segment is part of a filter belt, it can be compressed and held in place by one or more closing elements to close a treatment area of ​​the sorption system. The filter belt can continue to run during this process, so that the connecting segment is stretched or elongated in the longitudinal direction. In this way, the filter belt can continue to run while a filter segment is located in a treatment area of ​​the sorption system.The at least one connecting segment comprises an elastically deformable material. The elastically deformable connecting segment can comprise one or more elastomers and / or rubbers and / or high-temperature wools, in particular also open-cell, preferably closed-cell polyurethanes or nitrile rubbers, polysiloxanes, or silicones. The at least one connecting segment is compressible. The at least one connecting segment is more compressible than the filter segment. The at least one connecting segment is essentially gas-tight in the compressed state. The at least one connecting segment is essentially air-impermeable in the compressed state. When the at least one connecting segment is compressed, its height, i.e., its thickness, is reduced. The at least one connecting segment allows the residence time of the sorption filter in the desorption zone to be lengthened or shortened without changing the velocity in the adsorption zone.Furthermore, a sorption filter according to the invention is preferred in which the at least one connecting segment contains no sorption material or at least less sorption material than the filter segment. The at least one connecting segment is preferably free of sorption material. Due to production-related contamination, the at least one connecting segment may contain a comparatively small proportion of sorption material.

[0044] The sorption filter according to the invention is further advantageously enhanced by one or more sensors for sensing properties of the sorption filter and / or properties of the sorption filter's environment. The one or more sensors can comprise a pressure sensor, a temperature sensor, a humidity sensor, a sensor for detecting the concentration of at least one substance, and / or a sensor for detecting fluid velocity. A sensor can be configured to detect a color change in or on the sorption filter. The one or more sensors can be capable of wireless communication. The one or more sensors can be configured to communicate actively, in particular automatically, or passively, in particular in response to a query.One or more sensors can ensure operational reliability during the operation of the sorption plant, increase productivity, and / or reduce energy consumption. One or more sensors can be used to control the sorption plant. One or more sensors can indicate the aging status or the need to replace filter segments or the sorption filter.

[0045] The problem underlying the invention is further solved by a sorption filter for sorbing and / or desorbing at least one substance for use in a sorption system, comprising several filter segments, each of which includes a sorption layer containing at least one sorption material, and at least one connecting segment that joins two filter segments together along a longitudinal direction. The several filter segments and / or their at least one sorption layer exhibit lower elastic deformability, in particular lower longitudinal extensibility, than the at least one connecting segment. The sorption material is, for example, a sensitive, porous, and / or granular sorbent.

[0046] The filter segments can have one or more of the features described above. The filter segments are preferably not stretchable and / or inflexible in the longitudinal direction. Alternatively or additionally, the filter segments can also be designed as laminates or foams, or comprise laminates or foams. The filter segments do not necessarily have to have a multi-layered structure. Preferably, the multiple filter segments have a different segment height and / or a different segment length than the at least one connecting segment.

[0047] The at least one connecting segment can have one or more of the features described above. Preferably, the at least one connecting segment has a different, and in particular a higher, compressibility along the vertical axis than the multiple filter segments. This high compressibility ensures a reliable seal in the area of ​​the connecting segment. The at least one connecting segment can be taller than the filter segment, so that when the sorption filter is deflected by a deflection device, the filter segment comes into less or no contact with the deflection device, thereby reducing or completely preventing mechanical stress on the filter segments and resulting in reduced abrasion or mechanical damage. The at least one taller connecting segment can be compressible and possess resilience.In an advantageous embodiment, the resilience is so high that the connecting segments return completely or almost completely to their uncompressed state. The at least one connecting segment can be flatter than the filter segment, so that the sorption filter consists predominantly of filter segments, thus minimizing dead volume in the treatment chambers. Alternatively, the at least one connecting segment can be shorter than the filter segment, so that the sorption filter consists predominantly of filter segments. In an advantageous embodiment, the at least one connecting segment has a particularly low heat capacity, resulting in minimal heat input into the at least one treatment area.The problem underlying the invention is further solved by a connecting segment of the type mentioned at the outset, wherein the connecting segment according to the invention has a deformation area arranged between the first connecting area and the second connecting area, which is deformable, in particular elastically deformable.

[0048] The connecting segment according to the invention is preferably a connecting segment for a sorption filter according to one of the embodiments described above. The connecting segment can have one or more of the features described above. With regard to the advantages and modifications of the connecting segment according to the invention, reference is therefore made to the advantages and modifications of the sorption filter according to the invention and its connecting segment.

[0049] In a preferred embodiment of the connecting segment according to the invention, at least one connecting area is elastically deformable, in particular stretchable in the longitudinal direction. Preferably, the connecting segment is stretchable in the longitudinal direction and the deformation area is compressible perpendicular to the longitudinal direction. The deformation area can be configured such that the material of the deformation area conforms to a seal of a treatment area of ​​the sorption system above and below the point to be sealed.

[0050] The problem underlying the invention is further solved by a filter segment of the type mentioned above, wherein the multiple layered composites of the filter segment according to the invention are movable relative to one another in the longitudinal direction. The sorption material is, for example, a sensitive, porous and / or granular sorbent.

[0051] The filter segment according to the invention is preferably a filter segment for a sorption filter according to one of the embodiments described above. The filter segment can have one or more of the features described above. With regard to the advantages and modifications of the filter segment according to the invention, reference is therefore made to the advantages and modifications of the sorption filter according to the invention and its filter segment. The sorption material can be immobilized by means of at least one fixing agent and fixed to the at least one support layer.

[0052] The problem underlying the invention is further solved by a sorption system of the type mentioned above, wherein the at least one sorption filter of the sorption system according to the invention is designed according to one of the embodiments described above and / or comprises a connecting segment according to one of the embodiments described above and / or a filter segment according to one of the embodiments described above. With regard to the advantages and modifications of the sorption system according to the invention, reference is therefore first made to the advantages and modifications of the sorption filter according to the invention, the advantages and modifications of the connecting segment according to the invention, and the advantages and modifications of the filter segment according to the invention.

[0053] Because the sorption system has a drive device for moving the sorption filter within the sorption system, the filter segments of the sorption filter can be moved within the sorption system.

[0054] In a preferred embodiment of the sorption system according to the invention, the drive unit comprises one or more rotaryally driven drive rollers for moving the sorption filter and / or one or more deflection devices, in particular deflection rollers, for deflecting the sorption filter. The one or more deflection rollers are rotatably mounted. The sorption filter rests, at least partially, against the circumference of the one or more deflection rollers. The sorption filter extends along the deflection rollers on a filter path. Consequently, a filter path for the sorption filter is defined by means of the deflection rollers. When the sorption filter is set in motion, it moves along the filter path.The filter web can have a closed path, particularly if the filter segments and the at least one connecting segment are designed as a circumferential filter belt. If the filter segments and the at least one connecting segment are designed as a circumferential filter belt, the sorption filter can move in a ring-like fashion. The sorption filter is deflected in certain sections by means of one or more deflection rollers. The sorption filter is preferably arranged such that at least a portion of the support layers of the multiple filter segments are located on the one or more deflection rollers. The sorption filter is preferably arranged such that the sorption layers of the multiple filter segments are positioned without contact with the one or more deflection rollers.Consequently, particularly when the sorption filter is set in motion, the force exerted by one or more deflection rollers on the sorption layers is reduced and / or distributed more evenly than when the sorption filter is arranged such that at least a portion of the sorption layers of the multiple filter segments are located on one or more deflection rollers. This prevents or reduces the detachment and / or abrasion of the sorption material from the sorption layers or from the support layers, and / or the displacement of the sorption material within the sorption filter. The sorption filter, preferably at least one connecting segment, bears at least temporarily against one or more drive rollers. The one or more drive rollers may each have a grooved circumference. The one or more drive rollers are rotatably mounted.The sorption filter can be set in motion by means of one or more drive rollers. The sorption filter is preferably arranged such that at least a portion of the support layers of the multiple filter segments are at least temporarily located on one or more drive rollers. The sorption filter is preferably arranged such that the sorption layers of the multiple filter segments are arranged without contact with the one or more drive rollers. Consequently, particularly when the sorption filter is set in motion, the force exerted by the one or more drive rollers on the sorption layers is reduced and / or distributed more effectively than if the sorption filter were arranged such that at least a portion of the sorption layers of the multiple filter segments were located on one or more drive rollers.This prevents the sorption material from detaching from the support layers and / or shifting within the sorption filter. The drive unit can include a motor. The one or more drive rollers are driven by the motor. The one or more drive rollers are set in rotation by the motor. Consequently, the sorption filter can be set in motion by the motor. The motor can be electrically, hydraulically, or pneumatically driven.

[0055] In an advantageous embodiment, the sorption system according to the invention comprises one or more treatment areas into which one or more filter segments of the sorption filter can be moved, wherein the one or more treatment areas are configured to treat the one or more filter segments. In the case of multiple treatment areas, the multiple treatment areas can have different sizes and / or geometries, and in particular, can also offer different capacities for filter segments. The one or more filter segments of the sorption filter can also be moved out of the one or more treatment areas. The one or more treatment areas can be gas chambers and / or air chambers. The sorption system can include a reservoir, for example, in a sorption area or at least one treatment area.The at least one reservoir can serve to compact filter segments in at least one area, thereby increasing the cumulative energy efficiency of the sorption / desorption process and / or ensuring improved, particularly accelerated, sorption and / or desorption of at least one substance. Treating the one or more filter segments can include humidifying and / or dehumidifying and / or cooling and / or heating them. Treating the one or more filter segments can also include initiating a desorption process to desorb at least one substance from them, for example, based on specific temperatures and / or pressures.In the case of multiple treatment areas, at least one other area preferably has conditions that differ from those of the other areas, allowing for the performance of different tasks, such as heating, cooling, pressure reduction, pressurization, at least partial desorption of at least one substance per treatment area, or at least partial conversion of at least one substance per treatment area. In one embodiment of the sorption system, partial separation of two desorbed substances can also be achieved, for example, by partial condensation, in at least one treatment area each.

[0056] In another preferred embodiment of the sorption system according to the invention, different treatment parameters can be set in one or more treatment areas. The values ​​of the treatment parameters in the one or more treatment areas differ from the values ​​of the ambient parameters. The treatment parameters and ambient parameters can, for example, relate to the pressure and / or temperature and / or humidity and / or the concentration of at least one substance and / or the speed of the belt in at least one sorption zone and / or treatment zone and / or the availability of energy, for example, heat, cold, or electricity. The temperature can refer to the air temperature, the inner wall temperature of the one or more treatment areas, and / or the temperature of the sorption filter. The pressure can refer to the atmospheric pressure.The values ​​of the treatment parameters in the one or more treatment areas can be recorded by at least one sensor. Alternatively or additionally, electronically provided treatment parameters can be set in the one or more treatment areas of the sorption system.

[0057] The sorption system according to the invention is further advantageously developed in that one or more treatment areas are configured to initiate different separation processes. These different separation processes are initiated by setting area-specific treatment parameters. For example, a first temperature and pressure are set in a first treatment area, and a second temperature and pressure are set in a second treatment area. A first treatment area can be configured to initiate the separation of a first substance, for example, carbon dioxide. A second treatment area can be configured to initiate the separation of a second substance, for example, water. The separation of carbon dioxide can be a process called carbon dioxide harvesting.The separation of water can represent a reduction in the water content in one or more filter segments.

[0058] The sorption system according to the invention is further advantageously developed by providing at least one treatment area for converting the sorbed substance into a process material, with or without desorption, particularly using one or more conversion aids. This treatment area thus enables in-situ utilization. The conversion of the sorbed substance can be carried out chemically. A water-gas shift reaction or steam reforming can be used for the conversion. Alternatively, the conversion of the sorbed substance can be carried out electrochemically, particularly by adding at least one conversion aid, for example, hydrogen. The addition of the at least one conversion aid can induce desorption or conversion of the substance.The addition of at least one conversion aid can cause the conversion of at least one substance in the sorbed or desorbed state. The sorbed substance can be converted, for example, into synthesis gas, methane, methanol, ethane, ethylene, ethanol, formic acid, or carbon monoxide. The conversion of the sorbed substance can occur biologically, in particular by means of genetically modified microorganisms such as acetogenic bacteria and archaea. The sorbed substance can be converted, for example, into plastics such as polyethylene or polypropylene. The sorbed substance can be converted, for example, by artificial photosynthesis, in particular to butanol or hexanol. The sorbed substance can be converted, for example, by natural photosynthesis, in particular by plants, algae, microalgae, or cyanobacteria. The sorbed substance can be converted, for example, thermocatalytically and / or photocatalytically.The sorbed substance can be converted, for example, by copolymerization, particularly to polycarbonates or polyols. The sorbed substance can also be converted, for example, by electrofermentation and / or mineralization, or by plasma treatment.

[0059] In a further preferred embodiment of the sorption system according to the invention, at least a part of the at least one treatment area is movable towards the sorption filter and / or can be brought close to the sorption filter. By moving at least a part of the at least one treatment area towards the sorption filter or by bringing at least a part of the at least one treatment area close to the sorption filter, the dead space is reduced. The less dead space there is in the treatment area, the less energy has to be expended for generating a vacuum and / or changing the temperature.

[0060] In another preferred embodiment of the sorption system according to the invention, the number of filter segments of the sorption filter is greater than the number of treatment zones of the sorption system. Because the number of filter segments of the sorption filter is greater than the number of treatment zones of the sorption system, while one filter segment is located within one or more treatment zones, at least one other filter segment is located outside of one or more treatment zones. Consequently, for example, a filter segment located within one or more treatment zones can desorb the at least one substance, while a filter segment located outside of one or more treatment zones can adsorb the at least one substance.

[0061] The sorption system according to the invention is further advantageously developed by a compressor, in particular a vacuum pump, for adjusting the pressure, in particular for generating a negative pressure, especially a vacuum, within at least one treatment area. The compressor can change the air pressure within the at least one treatment area. The compressor can increase or decrease the air pressure within the at least one treatment area. The compressor can be designed as a compressor, in particular a piston compressor. The compressor designed as a vacuum pump can be a positive displacement pump, rotary vane pump, rotary lobe pump, sliding vane pump, jet pump, molecular pump, or turbomolecular pump. A high vacuum, ultra-high vacuum, or extremely high vacuum can be generated by means of the compressor designed as a vacuum pump.The compressor can provide a negative pressure of <500 mbar, preferably <200 mbar, particularly preferably in the range of 1-200 mbar, and most preferably in the range of 30-130 mbar. Providing negative pressure via a compressor can increase the purity of the at least one desorbed substance, for example, by reducing fluid components, especially air components such as nitrogen and oxygen. Providing negative pressure via a compressor can extend the lifetime of the at least one sorbent by reducing degradation, particularly by reducing oxygen content and thus oxidation. Providing negative pressure via a compressor can increase the desorption rate of the at least one substance.

[0062] In a further embodiment, the sorption system according to the invention is configured to bring about a change in concentration, in particular an increase in concentration, of at least one substance, preferably water vapor, in at least one treatment area.

[0063] In another embodiment, the sorption system according to the invention comprises a closing device comprising one or more closing elements for closing one or more treatment areas, in particular by bringing the one or more closing elements into contact with one or more connecting segments of the sorption filter. The closing device allows one or more connecting segments to be clamped or compressed by the one or more closing elements. When the one or more connecting segments are clamped, the one or more treatment areas are sealed gas-tight. When the one or more treatment areas are sealed gas-tight by clamping the one or more connecting segments, a vacuum can be generated within the one or more treatment areas.The at least one locking device can be designed such that the connecting segment assumes essential locking properties, for example by clamping or reversible compression, so that no or only minimal drive of the one or more locking elements is required. The locking device can be operated or actuated by a drive. The drive can include a motor. The motor can be electrically, hydraulically, or pneumatically driven. The locking device can include a locking mechanism or be designed as a locking mechanism. The one or more locking elements can be made of metal, plastic, and / or a composite material.

[0064] In a particularly preferred embodiment, the sorption system according to the invention comprises a control device configured to control and / or regulate the drive device for moving the sorption filter and / or a drive of the closing device. The drive of the closing device serves to move one or more closing elements. The drive device for moving the sorption filter and the drive of the closing device are preferably controlled and / or regulated in a coordinated manner by means of the control device, for example, depending on environmental conditions.The drive unit for moving the sorption filter and the drive unit for the closing mechanism can be coordinated by the control unit, for example, such that after the drive stops, resulting in no movement of the sorption filter, the closing mechanism at least partially closes one or more treatment areas. Furthermore, the closing mechanism can at least partially open one or more treatment areas immediately before the drive is activated, which sets the sorption filter in motion.

[0065] Furthermore, a sorption system according to the invention is preferred, which includes a heating device. The heating device is preferably configured to heat one or more treatment areas. A specific temperature can be set in each of the treatment areas by means of the heating device. The heating device can be configured to heat the one or more treatment areas. The heating device can comprise a heating coil, electric surface heating, electromagnetic induction coil, heat exchanger, radiant heating, in particular an infrared radiator, or a waste heat boiler. The heating device can include a temperature sensor and / or a temperature controller. Heating the one or more treatment areas by means of the heating device can, for example, enable or accelerate the desorption of the at least one substance from the sorption filter.The sorption system may include a cooling device for cooling one or more treatment areas.

[0066] The sorption system according to the invention is further advantageously enhanced by a device for recovering heat from areas, in particular treatment areas and sorption areas, of the sorption system and / or for absorbing heat from the environment of the sorption system. The heat recovery device significantly increases the energy efficiency of the sorption system. The heat recovery device can, for example, recover and / or absorb heat from internal and / or external heat sources, such as waste heat sources. For example, the heat recovery device can also recover or absorb heat from fluid flows. The integration of temperature levels below the environment and treatment areas, such as well water or cooling circuits, also enables an increase in efficiency.In all such cases, heat exchangers, especially those with multiple circuits, are particularly well suited to maximizing the recovery rate, efficiency, and ultimately the energy efficiency of the process and / or the system.

[0067] In a further embodiment, the sorption system according to the invention is configured to absorb energy from the environment or at least one area via a refrigerant and / or the at least one substance, such that a refrigerant evaporates or is desorbed in at least one further sorbent, and at least one further area is cooled by the resulting evaporative cooling. Additionally or alternatively, due to the sorption of at least one substance in at least one sorbent of the sorption filter and / or due to the sorption of a refrigerant in at least one further sorbent and / or in a third sorbent of the heating / cooling circuit, the at least one substance and / or the at least one gaseous refrigerant can be sorbed and / or condensed. The at least one resulting enthalpy of condensation can be supplied in the form of heat to at least one area and / or the heating / cooling circuit.The resulting integration of an adsorption chiller and / or adsorption heat pump and / or absorption heat pump, each containing at least one circuit, increases the efficiency and thus the energy efficiency of the sorption system. The sorption system can be designed to temporarily store heat. Particularly suitable sorbents for heat / cold circuits are zeolites, silica, and MOFs. Preferably, water, and especially water vapor from the environment or a treatment area, is used for heat / cold generation or recovery. This includes the integration of an adsorption chiller and / or adsorption heat pump and / or absorption heat pump, which utilizes water vapor from the environment and transfers the generated energy into the sorption system, preferably into at least one treatment area.

[0068] The problem underlying the invention is further solved by a method for operating a sorption system of the type mentioned above, wherein, within the framework of the method according to the invention, one or more connecting segments of the sorption filter are brought into contact with one or more closing elements of the sorption system to close the treatment area. The method according to the invention is preferably used to operate a sorption system according to one of the embodiments described above. With regard to the advantages and modifications of the method according to the invention, reference is therefore first made to the advantages and modifications of the sorption system according to the invention.

[0069] The method may additionally include the following step: moving one or more filter segments of the sorption filter, particularly those located outside the treatment area, while at least one other filter segment remains stationary within the treatment area. The method may additionally include the following step: setting the treatment parameters, such as temperature, pressure, and / or humidity, within the treatment area. The sorption filter may be moved continuously or semi-continuously. The sorption filter may be moved at different speeds. The method may additionally include the following step: releasing one or more closing elements of the sorption system from one or more connecting segments to open the treatment area.The process may additionally include the following step: moving at least one filter segment of the sorption filter out of the treatment area of ​​the sorption system. If at least one filter segment of the sorption filter is located within the sealed treatment area, sorption of the at least one substance into and / or on the at least one filter segment of the sorption filter is prevented, and desorption of the at least one substance from and / or on the at least one filter segment of the sorption filter is enabled. If at least one filter segment of the sorption filter is located outside the sealed treatment area, sorption of the at least one substance into and / or on the at least one filter segment of the sorption filter is enabled, and desorption of the at least one substance from and / or on the at least one filter segment of the sorption filter is prevented.While the at least one filter segment is located in the closed treatment area, the concentration of the at least one substance in the fluid, preferably air, located in the closed treatment area changes due to the desorption of the at least one substance from and / or the at least one filter segment of the sorption filter. The at least one substance desorbed from and / or the filter segment of the sorption filter is distributed in the fluid, preferably air, located in the closed treatment area.

[0070] The sorption filter need not run through the sorption system along its entire length, but can be compacted at one or more points within the system, particularly preferably in at least one treatment zone and / or before and / or after at least one treatment zone. Compaction within a treatment zone reduces the dead space to be evacuated and thus contributes to the energy efficiency of the process. Compaction before and / or after a treatment zone allows for an adapted, individual residence time in different zones at an unimpeded conveying speed of the sorption filter, thus enabling continuous operation.

[0071] In a preferred embodiment of the method according to the invention, bringing one or more connecting segments of the sorption filter into contact with one or more closing elements of the sorption system includes compressing one or more connecting segments, wherein the filter segments of the sorption filter are not compressed or are compressed less than the one or more connecting segments. Because the filter segments of the sorption filter are not compressed or are compressed less than the one or more connecting segments, the wear of the filter segments is reduced compared to the case where the filter segments of the sorption filter are compressed to the same extent as the connecting segments.

[0072] Furthermore, a method according to the invention is advantageous in which, when compressing one or more connecting segments, the sorption material of one or more filter segments located in the at least one treatment chamber is not moved. Because the sorption material of the one or more filter segments is not moved when compressing one or more connecting segments, the wear of the one or more filter segments, or of the sorption filter, is reduced compared to the case where the sorption material of the one or more filter segments is moved when compressing one or more connecting segments.

[0073] The method according to the invention is advantageously further developed by having one or more sensors detect properties of the sorption filter and / or properties of the sorption filter's environment. The one or more sensors preferably detect pressure, temperature, humidity, the concentration of at least one substance, and / or fluid velocity. A sensor can detect a color change in or on the sorption filter. The one or more sensors can communicate actively, particularly automatically, or passively, particularly in response to a query. The one or more sensors can ensure operational reliability during the operation of the sorption system, increase productivity, and / or reduce energy consumption. The one or more sensors can be used to control the sorption system. The one or more sensors can determine the aging state or...Indicate the need to replace the filter segment or sorption filter.

[0074] In a further embodiment of the method according to the invention, at least a part of the at least one treatment area is moved towards the sorption filter and / or brought closer to the sorption filter. By moving at least a part of the at least one treatment area towards the sorption filter or bringing at least a part of the at least one treatment area closer to the sorption filter, the dead space is reduced. The less dead space exists in the treatment area, the less energy has to be expended for generating a vacuum and / or changing the temperature.

[0075] In a further embodiment of the method according to the invention, energy is absorbed from the environment or at least one area via a refrigerant and / or the at least one substance, causing a refrigerant to evaporate or desorb in at least one further sorbent, and resulting in the cooling of at least one further area by means of evaporative cooling. Additionally or alternatively, due to the sorption of at least one substance in at least one sorbent of the sorption filter and / or due to the sorption of a refrigerant in at least one further sorbent and / or in a third sorbent of the heating / cooling circuit, the at least one substance and / or the at least one gaseous refrigerant can be sorbed and / or condensed. The at least one resulting enthalpy of condensation can be supplied in the form of heat to at least one area and / or the heating / cooling circuit.The resulting integration of an adsorption chiller and / or adsorption heat pump and / or absorption heat pump, each containing at least one circuit, increases the efficiency and thus the energy efficiency of the process. The process can be designed such that heat is temporarily stored. Particularly suitable sorbents for heat / cold circuits are zeolites, silica, and MOFs. Preferably, water, and especially water vapor from the environment or a treatment area, is used for heat / cold generation or recovery. This includes the integration of an adsorption chiller and / or adsorption heat pump and / or absorption heat pump, which utilizes water vapor from the environment and transfers the generated energy into the process, preferably into at least one treatment area.

[0076] The problem underlying the invention is further solved by a manufacturing process of the type mentioned at the outset, wherein, within the framework of the manufacturing process according to the invention, two filter segments are connected by means of the connecting segment. A sorption filter according to one of the embodiments described above is preferably produced by means of the manufacturing process according to the invention. With regard to the advantages and modifications of the manufacturing process according to the invention, reference is therefore first made to the advantages and modifications of the sorption filter according to the invention.

[0077] The production of the filter segments can include mixing sorbent material with a fixative to form a material mixture, trickling the material mixture onto a support layer, and melting the material mixture. The production of the filter segments can also include stacking at least one, preferably several, layer composites, each comprising a sorbent layer and a support layer, on top of each other, and / or cutting several layer composites or a stack of layer composites. Preferably, several filter segments and several connecting segments are joined together to form a filter belt. The production process can additionally include the following step: attaching at least one retaining element to the several filter segments. The production process can also additionally include the following step: producing or providing a sheathing for the several filter segments or sheathing the provided layer composites.The manufacturing process may additionally include the following step: arranging, or winding, and / or closing the previously at least partially open casing around the one or more filter segments.

[0094] Fig. 16 shows a sorption filter according to the invention in a schematic top view;

[0095] Fig. 17 shows another sorption filter according to the invention in a schematic top view; and

[0096] Fig. 18 shows a schematic representation of a production plant for carrying out the manufacturing process according to the invention. Fig. 1 shows a sorption filter 10, which is suitable for sorbing and desorbing a substance, in this case carbon dioxide, and can be used in a sorption plant 100.

[0097] The sorption filter 10 comprises several filter segments 12a, 12b, which are connected to one another via a connecting segment 14. The connecting segment 14 has a first connecting area 16a and a second connecting area 16b. The first connecting area 16a is connected to a first filter segment 12a of the sorption filter 10. The second connecting area 16b is connected to a second filter segment 12b of the sorption filter 10. The connecting segment 14 includes a deformation area 18 arranged between the first connecting area 16a and the second connecting area 16b, which is elastically deformable. Additionally or alternatively, at least one connecting area 16a, 16b can be elastically deformable, in particular stretchable in the longitudinal direction. In a particularly preferred embodiment, the connecting segment 14 is stretchable in the longitudinal direction and the deformation area 18 is compressible perpendicular to the longitudinal direction.In a particularly preferred variant, the deformation area 18 can be designed such that the material of the deformation area 18 conforms to the seal of the treatment area above and below the point to be sealed.

[0098] The connecting segment 14 can connect the filter segments 12a, 12b to each other, for example, by means of a force-fit, form-fit and / or material-fit connection.

[0099] Filter segments 12a and 12b have a segment height SHF and a segment length SLF. Connecting segment 14 has a segment height SHV ​​and a segment length SLV. The segment length SLV of connecting segment 14 is less than the segment length SLF of filter segments 12a and 12b. Because connecting segment 14 has a shorter segment length SLV than filter segments 12a and 12b, it is shorter. The segment height SHV ​​of connecting segment 14 is less than the segment height SHF of filter segments 12a and 12b. Because connecting segment 14 has a shorter segment height SHV ​​than filter segments 12a and 12b, it is thinner than filter segments 12a and 12b.

[0100] The filter segments 12a, 12b each have several layer assemblies 20a-20c that are movable relative to each other. These layer assemblies 20a-20c are in contact with each other and slide past each other during relative movement. In the illustrated embodiment, the filter segments 12a, 12b each have three layer assemblies 20a-20c that are movable relative to each other. The layer assemblies 20a-20c that are movable relative to each other have an identical layer structure, identical layer thicknesses, and identical layer material.

[0101] The layered composites 20a-20c each comprise a sorption layer 26 containing sorption material 28 and a support layer 22 for the

[0102] Sorption material 28. The sorption material 28 is immobilized by means of a fixative 24 and fixed to the carrier layer 22 of the respective layer assembly 20a-20c. Because the layer assembly 20a-20c each comprise a sorption layer 26 and a carrier layer 22, the sorption layer 26 and the carrier layer 22 of the first layer assembly 20a and the sorption layer 26 and the carrier layer 22 of the second layer assembly 20b are movable relative to each other. The layer assembly 20a-20c is arranged such that the sorption layer 26 of the layer assembly 20a moves relative to the carrier layer 22 of the adjacent layer assembly 20a-20c.

[0103] layer composite 20b touches and the sorption layer 26 of the

[0104] layer composite 20b the support layer 22 of the adjacent

[0105] Layered composite 20c touched.

[0106] The support layers 22 are air-permeable. They exhibit a comparatively high air permeability, allowing the air containing the substance to be absorbed to flow through them with minimal resistance. Consequently, the absorption of the substance is accelerated, as its accumulation in and on the sorption layers 26 is accelerated. Furthermore, the desorption of the substance is accelerated, as its release from and to the sorption layers 26 is accelerated. The support layers 22 have a porous structure, such as a foam or nonwoven structure. Each support layer 22 can be designed as an air-permeable textile.

[0107] The sorption material 28 enables the substance to be sorbed on and / or in the sorption layers 26 of the filter segments 12a, 12b. The sorption material 28 is granular or powdery.

[0108] The support layers 22 each carry a sorption layer 26. The fixative 24 is located between the support layers 22 and the sorption layers 26 of the filter segments 12a, 12b. By immobilizing the sorption material 28 by means of the fixative 24 and fixing it to the respective support layers 22, relative movement of the sorption material 28 or the sorption layers 26 to the support layer 22 carrying the sorption material 28 is prevented. Furthermore, the fixation of the sorption material 28 by means of the fixative 24 prevents abrasion of the sorption material 28. In the illustrated embodiment, the fixative 24 forms fixative layers on the respective carrier layers 22. Because the sorption material 28 is immobilized by the fixative 24 and fixed to the carrier layers 22, the sorption material 28 adheres to the carrier layers 22. The fixative 24 is an adhesive, namely a sprayed-on hot melt adhesive.

[0109] The filter segments 12a, 12b each comprise a cover layer 30. The cover layers 30 each lie on the uppermost sorption layer 26 and cover it.

[0110] Filter segments 12a, 12b each have a retaining element 32a, 32b, which holds together the multiple layered composites 20a-20c of the respective filter segments 12a, 12b. Because the respective retaining elements 32a, 32b hold the multiple layered composites 20a-20c together, it is also ensured that the multiple layered composites 20a-20c of the filter segments 12a, 12b are in contact with each other. The retaining elements 32a, 32b each surround several layered composites 20a-20c and are designed as a sheath. The retaining elements 32a, 32b, designed as a sheath, completely surround the layered composites 20a-20c of the filter segments 12a, 12b. The sheath is air-permeable and can, for example, be an air-permeable textile.

[0111] Fig. 2 shows a filter segment 12 with several layered composites 20a-20c. Each layered composite 20a-20c has a support layer 22 and sorption material 28 fixed to the support layer 22 by a fixative 24. The sorption material 28 forms sorption layers 26 on the respective support layers 22.

[0112] The stacked layered composites 20a-20c are held together by a retaining element 32 designed as a sheath. The layered composites 20a-20c of the filter segment 12 are movable relative to each other in the longitudinal direction L1, L2. The retaining element 32, designed as a sheath, is deformable and thus allows the relative movement of the layered composites 20a-20c in the longitudinal direction L1, L2.

[0113] The mutually movable layered assemblies 20a-20c each have a smooth surface. Consequently, the surfaces of the several mutually movable layered assemblies 20a-20c exhibit a comparatively low sliding friction, so that the layered assemblies 20a-20c can slide along each other in contact during a relative movement in the longitudinal direction L1, L2.

[0114] Figures 3 to 5 show the production of a filter segment 12 for a sorption filter 10.

[0115] As shown in Fig. 3, two layered composites 20a, 20b are initially provided, each of which has a support layer 22 and sorption material 28 fixed to the support layer 22 by a fixative 24. The sorption material 28 forms a sorption layer 26 on each of the support layers 22. The layered composites 20a, 20b are initially stacked loosely on top of each other, allowing relative movement between them.

[0116] As shown in Fig. 4, a further layered composite 20c is then provided, wherein the layered composite 20c has a carrier layer 22 and sorption material 28 fixed to the carrier layer 22 by a fixing agent 24. The sorption material 28 forms a sorption layer 26 on the carrier layer 22.

[0117] The layered composite 20c is initially loosely stacked on top of the composite package consisting of the layered composites 20a, 20b, so that a relative movement of all layered composites 20a-20c is possible.

[0118] As shown in Fig. 5, the filter segment has a cover layer 30. The cover layer 30 can either be applied to the composite package of the layer combinations 20a-20c or separately to the layer combination 20c beforehand.

[0119] The layered composites 20a-20c are held together by means of a retaining element 32 designed as a sheathing in such a way that the layered composites are held in a stacked arrangement and yet a relative movement of the layered composites 20a-20c in the longitudinal direction is possible.

[0120] Fig. 6 shows a sorption system 100 for sorbing and desorbing a substance, for example carbon dioxide from the ambient air.

[0121] The sorption system 100 comprises a sorption filter 10 designed as a circumferential filter belt. The sorption filter 10 has a plurality of filter segments 12a-12c and a plurality of connecting segments 14a-14c, wherein adjacent filter segments 12a-12c are connected to each other by means of a connecting segment 14a-14c arranged between the adjacent filter segments 12a-12c.

[0122] The sorption system 100 further comprises a drive unit 102 for moving the sorption filter 10 within the sorption system 100. Because the sorption system 100 has a drive unit 102 for moving the sorption filter 10 within the sorption system 100, the filter segments 12a-12c of the sorption filter 10 can be moved within the sorption system 100. The drive unit 102 has a rotaryally driven drive roller 104 for moving the sorption filter 10 and several deflection rollers 106a-106c for deflecting the sorption filter 10. The deflection rollers 106a-106c are rotatably mounted. The sorption filter 10 rests against the circumference of the deflection rollers 106a-106c in certain areas. The drive unit 102 includes a motor. The drive roller 104 is driven by the motor and set into rotation.

[0123] The sorption filter 10 extends along the deflection rollers 106a-106c on a continuous filter track. Consequently, the deflection rollers 106a-106c define a continuous filter track for the sorption filter 10. When the sorption filter 10 is set in motion, it moves along the continuous filter track. The filter track has a closed path.

[0124] The sorption system 100 comprises a treatment area 108, into which a filter segment 12a-12c of the sorption filter 10 can be moved in and out, wherein the treatment area 108 is designed to treat the filter segment 12a-12c.

[0125] Treatment area 108 is an air chamber. Various treatment parameters can be set within treatment area 108. The values ​​of these treatment parameters can differ from the values ​​of the ambient parameters. The adjustable treatment parameters may include, for example, pressure, temperature, and / or humidity. The values ​​of the treatment parameters within treatment area 108 can be detected by a sensor.

[0126] In sorption systems 100 with multiple treatment areas 108, the multiple treatment areas 108 can be configured to initiate different separation processes. These different separation processes are then initiated, for example, by setting area-specific treatment parameters. In the illustrated embodiment, treatment area 108 is configured to initiate the separation of carbon dioxide. The sorption system 100 could be extended by adding further treatment areas 108, for example, for dehumidifying and / or cooling and / or heating the filter segments 12a-12c.

[0127] The sorption system 100 further comprises a compressor (not shown) for adjusting the pressure within the treatment area 108. The compressor can be a vacuum pump for generating a vacuum within the treatment area 108.

[0128] To close the treatment area 108, the sorption system 100 has a closing device 110 comprising several closing elements 112a, 112b. Closing is achieved by bringing the closing elements 112a, 112b into contact with two connecting segments 14a-14c of the sorption filter 10. Using the closing device 110, connecting segments 14a-14c of the sorption filter 10 can be clamped between the closing elements 112a, 112b and compressed for sealing purposes. When the connecting segments 14a-14c are clamped, the treatment area 108 is sealed gas-tight. When the treatment area 108 is sealed gas-tight by clamping the connecting segments 14a-14c, a vacuum can be generated within the treatment area 108.

[0129] The locking device 110 can be driven or actuated by means of a drive. The drive of the locking device 110 serves to move the locking elements 112a, 112b. The drive can include a motor. The sorption system 100 includes an electronic control unit, which is configured to control the drive unit 102 for moving the sorption filter 10 and the drive of the locking device 110. The drive unit 102 for moving the sorption filter 10 and the drive of the locking device 110 are controlled in a coordinated manner by means of the control unit.The control of the drive unit 102 for moving the sorption filter 10 and the control of the drive of the closing device 110 are coordinated by the control unit in such a way that when or after the drive stops, resulting in no movement of the sorption filter 10, the treatment area 108 is closed by means of the closing device 110. Furthermore, the treatment area 108 is opened by controlling the closing device 110 immediately before the drive is activated, which sets the sorption filter 10 in motion.

[0130] The sorption system 100 includes a heating device (not shown) which is designed to heat the treatment area 108. A target temperature can be set in the treatment area 108 using the heating device.

[0131] During operation of the sorption plant 100, carbon dioxide is adsorbed in and / or on the filter segments 12a-12c of the sorption filter 10 outside the treatment area 108. The filter segments 12a-12c of the sorption filter 10 are then moved into the treatment area 108 of the sorption plant 100. In the treatment area 108, carbon dioxide is desorbed from and / or off the filter segments 12a-12c of the sorption filter 10 within the treatment area.

[0132] The filter segments 12a-12c and the connecting segments 14a-14c of the sorption filter 10 are replaceable without damage. Consequently, individual or multiple worn or damaged segments of the sorption filter 10 can be replaced, thus ensuring the functionality of the sorption filter 10, particularly over a longer service life.

[0133] Fig. 7 shows the deformation of a connecting segment 112 of a sorption filter 10 when a treatment area 108 of a sorption system 100 is closed. On the left side of the figure, the treatment area 108 is in an open state. On the right side of the figure, the treatment area 108 is in a closed state.

[0134] When the treatment area 108 closes, a closing element 112 of a closing device 110 of the sorption system 100 is brought into contact with a connecting segment 14, which connects two filter segments 12 (not shown), causing the connecting segment 14 to deform. The connecting segment 14 is designed such that its outer legs are pressed laterally against the closing element 112 when the treatment area 108 closes, creating additional contact areas and improving the sealing effect.

[0135] Figures 8 and 9 each show a compacted area of ​​a sorption filter 10, wherein the filter segments 12 of the sorption filter 10 are upright in the compacted area and aligned parallel to each other.

[0136] Beyond the compacted area, the sorption filter 10 is elongated such that the longitudinal axis of the horizontally oriented and serially arranged filter segments 12 runs parallel or aligned with the longitudinal axis of the sorption filter 10. The elongated area is located, for example, in the region shown by the arrow.

[0137] Compacting the sorption filter 10 within a treatment area 108 reduces the dead space to be evacuated and thus contributes to the energy efficiency of the process. Compacting before and / or after a treatment area 108 allows for an adapted, individual residence time in different areas at an unimpeded conveying speed of the sorption filter 10, thus enabling continuous operation.

[0138] In the sorption filter 10 shown in Fig. 8, the connecting segments 14a-14e connecting the filter segments 12 are comparatively short and each connects the ends of adjacent filter segments 12 on only one side, i.e. either on the underside or on the top side, of the sorption filter 10.

[0139] In the sorption filter 10 shown in Fig. 9, the connecting segments 14a-14e that link the filter segments 12 are comparatively long and each connects an upper end of one filter segment 12 with a lower end of the adjacent filter segment 12. Figs. 10 and 11 show a cylindrical filter segment 12 and a sorption filter 10 with several such filter segments 12. The cylindrical filter segment 12 has several cylindrical layers which are slidable relative to each other.

[0140] The cylindrical layers are nested hollow cylindrical layer composites 20a-20c, which contain sorption material 28. The sorption material 28 can, for example, be immobilized by means of a fixative 24 and fixed to a cylindrical support layer 22. The cylindrical filter segments 12 are connected to each other via connecting segments 14, the connecting segments 14 being connected to the outer surface of the filter segments 12. The outer surface is formed by the retaining element 32.

[0141] In other embodiments, the cylindrical filter segments 12 can include a lid and / or bottom, so that the filter segments 12 may, for example, have a closed or open cup shape.

[0142] Furthermore, the outer surface and / or at least a bottom or lid can be designed as a round flat sheet or ring-shaped like a pair of glasses and contain sorption material. The lid and / or bottom can also be attached via a spacer. Furthermore, the cylindrical filter segment 12 can have one or more wound layer composites. The winding can be designed, for example, like that of a paper roll.

[0143] Figures 12 and 13 also show a filter segment 12 and a sorption filter 10 with several such filter segments 12. The cylindrical filter segment 12 again has several cylindrical layers which are slidable relative to one another. The cylindrical layers are composite layers 20a-20c which contain sorption material 28. In this case, the connecting segments 14 are connected to the end faces of the cylindrical filter segments 12.

[0144] Figures 14 and 15 show a filter segment 12 and a sorption filter 10 with several such filter segments 12. Figure 14 shows that the layer composites 20a-20c are formed by coaxial ring structures of different diameters, which are nested inside one another.

[0145] In other embodiments, the filter segments 12 can be formed by cylinders with an H-shaped cross-section. These cylinders can include a material plane that forms the central leg of the H-shape. The lateral surface can act as a support for the material plane. The material plane can consist of a support layer containing sorbents.

[0146] Several such cylindrical filter segments 12 with an H-shaped cross-section and different pressure gauges can be inserted into one another or stacked on top of each other.

[0147] The top view of a sorption filter 10 shown in Fig. 16 demonstrates that the sorption filter can have a uniform width. The filter segments 12a-12d have a segment width SBF. The connecting segments 14a-14c have a segment width SBV. The segment width SBF of the filter elements 12a-12c corresponds to the segment width SBV of the connecting segments 14a-14c.

[0148] In other embodiments, the segment width SBF of the filter elements 12a-12c and the segment width SBV of the connecting segments 14a-14c may differ from each other.

[0149] As shown in Fig. 17, the connecting segments 14a-14c can also be components of a retaining element 32 designed as a tubular sheath. The retaining element 32 designed as a tubular sheath has connecting sections 34a-34c between the filter segments 12a-12d, in which the retaining element 32 designed as a tubular sheath has adhesive areas or seams that form the connecting segments 14a-14c between the filter segments 12a-12d.

[0150] Fig. 18 shows a manufacturing plant 200 for producing a sorption filter 10.

[0151] The production plant comprises material rolls 202a-202f, from which layered composite strip material, each with a carrier layer 22 and a sorption layer 26 supported by the carrier layer 22, is unwound via a winder 204. The layered composite strip material from the material rolls 202a-202f is first gathered into a layered composite stack.

[0152] The layered composite stack is then cut to length in a cutting station 206, for example in a cutting process. The resulting cut composite package 36 is then loosely placed onto a lower elastic retaining element 32a, which is unwound from the material roll 208a and rests on the conveyor belt of a conveying device 212.

[0153] After the lower elastic retaining element 32a has been advanced by means of the conveying device 212 by one composite package length, adhesive 38 is applied to the lower elastic retaining element 32a via an adhesive dosing station 210a, so that a connecting segment 14 can be positioned on the applied adhesive 38.

[0154] The lower elastic retaining element 32a is then advanced by the conveyor 212 by another composite package length. Adhesive 38 is then applied to the connecting segment 14 via an adhesive dosing station 210b. Subsequently, an upper elastic retaining element 32b is fed from the material roll 208b and bonded using the adhesive applied to the connecting segment 14.

[0155] The process continues until the intended filter length of the sorption filter 10 is reached.
