Description

Technical Field

[0001] This utility model relates to the technical field of gas adsorption equipment, specifically to a rain lintel with an adjustable opening angle and a carbon dioxide adsorption box. Background Technology

[0002] Direct air capture (DAC) is an emerging carbon sequestration technology that directly separates carbon dioxide from the atmosphere through chemical adsorption. The captured carbon dioxide can be permanently sequestered geologically or applied in industrial production fields such as synthetic fuels. The carbon dioxide adsorption chamber is a key component of industrial DAC plants, possessing advantages such as high capture efficiency, strong adaptability to operating conditions, and cyclic operation. It operates on an adsorption-desorption cycle mechanism, utilizing the selective adsorption characteristics of solid adsorbents such as zeolite molecular sieves, activated carbon, MOF materials, and amine functionalized materials packed in the adsorption bed to achieve efficient separation and purification of carbon dioxide from atmospheric mixtures.

[0003] Carbon dioxide adsorption chambers used for capturing low-concentration carbon dioxide in the atmosphere are mostly arranged outdoors, relying on an internal adsorption bed to directly capture the rare carbon dioxide in the air, and then producing high-purity carbon dioxide products after continuous capture and purification. However, under harsh outdoor conditions such as sandstorms and rain, sand and rainwater can easily enter the adsorption chamber and the adsorption bed with the airflow, seriously affecting the carbon dioxide adsorption and separation performance.

[0004] On the one hand, dust particles are easily embedded in the micropores and mesopores of the adsorbent, causing pore blockage and significantly reducing the specific surface area and carbon dioxide adsorption capacity of the adsorbent, resulting in a rapid decline in adsorption efficiency. On the other hand, dust accumulation in the gaps between adsorbent particles will increase airflow resistance, causing a significant increase in system wind pressure and operating energy consumption. Under extreme conditions, it can easily cause airflow deviation and channeling phenomena, significantly reducing the effective utilization rate of the adsorption bed.

[0005] On the other hand, commonly used carbon dioxide adsorbents such as molecular sieves, amine-modified adsorbents, and activated carbon generally have strong hydrophilicity. Water vapor will preferentially occupy the adsorption active sites, inhibiting carbon dioxide adsorption behavior, causing a sharp drop in adsorption capacity or even short-term failure. When the adsorbent is damp, it is prone to agglomeration and caking, causing adsorption bed clumping and local collapse, resulting in turbulent airflow distribution, airflow short circuits and flow dead zones, and disrupting the normal process operation of the system.

[0006] Existing open-air carbon dioxide adsorption boxes are prone to problems such as substandard decarbonization efficiency, increased operating energy consumption, shortened adsorbent replacement cycle, and soaring maintenance costs after being disturbed by sand and rain. At the same time, they can also cause many engineering drawbacks such as equipment pipeline blockage, structural corrosion, and increased failure rate, which restrict the long-term stable and economical operation of DAC devices. Utility Model Content

[0007] This utility model aims to solve the problems of substandard decarbonization efficiency, increased operating energy consumption, shortened adsorbent replacement cycle, and soaring maintenance costs that occur when existing open-air carbon dioxide adsorption boxes are affected by sandstorms and rain. This utility model provides the following technical solution:

[0008] An adjustable rain guard, comprising:

[0009] The mesh panel has multiple continuous air intake zones;

[0010] Multiple rain lint units, each located on the air inlet side of its corresponding air inlet area, each rain lint unit includes multiple stacked baffles and a first connecting rod. The end of each baffle near the air inlet area is rotatably connected to a mesh panel, and the end away from the air inlet area is rotatably connected to the first connecting rod. An air inlet channel is formed between adjacent baffles.

[0011] A linear drive mechanism is used to drive the first link of each rain lint unit to move, thereby causing the baffle of each rain lint unit to rotate. Each baffle can rotate to sequentially splice together to block the air inlet area, and can rotate to make the air inlet channel deliver air to the mesh plate at a predetermined angle.

[0012] Furthermore, in each rain lintel unit, the adjacent edges of two adjacent baffles have a cylindrical arc edge at the lower edge of the upper baffle and an inclined bevel at the upper edge of the lower baffle. When the air inlet channel is closed, the arc edge and the inclined bevel are in contact.

[0013] Furthermore, a storage groove is provided at the edge of the air intake area. When each air intake channel of each rain lintel unit is closed, each baffle rotates to accommodate the storage groove and fills the storage groove.

[0014] Furthermore, the predetermined angle is the angle between the air inlet channel and the mesh panel, which is 70° to 90°.

[0015] Furthermore, the longitudinal section of the air intake area is rectangular, and the baffle is a rectangular plate with one side equal to one side of the rectangle.

[0016] Furthermore, each rain lintel unit also includes a second link, and the two sides of each baffle are rotatably connected to the first link and the second link, respectively. The two apex angles of the baffle near the air inlet area are rotatably connected to the mesh plate, and the two apex angles away from the air inlet area are rotatably connected to the first link and the second link, respectively.

[0017] Furthermore, the continuous arrangement direction of each air intake zone is perpendicular to the continuous arrangement direction of each baffle in the rain lintel unit.

[0018] Furthermore, any two adjacent rain lintel units are fixedly connected by an adjacent first link and a second link.

[0019] Furthermore, the linear drive mechanism includes at least one electric cylinder, each electric cylinder being connected to the first link of at least one of the rain sill units to drive all rain sill units to move.

[0020] Furthermore, embodiments of this utility model also provide a carbon dioxide adsorption box, including a box body and the aforementioned adjustable rain lintel.

[0021] The chamber is equipped with multiple adsorption beds.

[0022] An adjustable rain lintel is installed on one side of the box, and the air inlet side of each adsorption bed is set to correspond one-to-one with the air inlet area of ​​the mesh plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model provides an adjustable-angle rain lintel, which divides the mesh panel into multiple independent air inlet zones. Each air inlet zone is equipped with a corresponding rain lintel unit. The rain lintel unit consists of multiple continuously arranged baffles and a first connecting rod connecting the baffles. An air inlet channel is formed between adjacent baffles. Under conditions of no sand or rain, the linear drive mechanism drives the first connecting rod to rotate the baffles, so that the air inlet channel maintains a preset opening angle. Airflow with a set direction is delivered to the mesh panel through the air inlet channel to meet the airflow requirements of the gas adsorption operation on the air outlet side of the mesh panel. Under severe conditions of sand or rain, the linear drive mechanism drives the baffles to rotate and close through the first connecting rod, so that the air inlet channel is completely closed. The baffles overlap to form an overall closed structure, completely blocking the air inlet side of the mesh panel, which can effectively prevent sand and rain from entering the interior and has a reliable rainproof and sandproof protection effect.

[0025] 2. The rain lintel with adjustable opening angle provided by this utility model can flexibly adjust the air intake angle of the air intake channel according to the real-time wind direction on the air intake side, which can significantly reduce airflow resistance, improve carbon dioxide gas adsorption efficiency, reduce system operating energy consumption, and thus reduce the overall operation and maintenance cost of the equipment.

[0026] 3. The present invention provides a rain lintel with an adjustable opening angle. In light rain conditions, the first connecting rod and each baffle can be deflected in real time by a linear drive mechanism according to the actual amount of rainfall. This allows for real-time adjustment of the opening of the air inlet channel and the tilt angle of the baffles, adapting to the rain protection needs of different falling angles. Rain protection can be achieved without completely closing the air inlet channel, greatly expanding the applicable range of the device.

[0027] 4. This utility model proposes a carbon dioxide adsorption box that integrates an adjustable-angle rain lint structure. Under normal operating conditions without sandstorms or rainfall, the air inlet areas of each mesh plate are directionally delivered to the corresponding adsorption bed air inlet side through the air inlet channel, allowing air to enter the adsorption bed in the optimal flow direction, effectively improving the adsorption efficiency of the adsorption bed for carbon dioxide, while reducing equipment operating energy consumption. Under severe conditions of sandstorms or rainfall, a linear drive mechanism drives the first connecting rod to drive each baffle to rotate synchronously, realizing the adaptive adjustment of the working posture of each rain lint unit. This effectively prevents sandstorms and rainwater from entering the box and adsorption bed with the airflow, fundamentally solving the problems of low decarbonization efficiency, increased operating energy consumption, shortened adsorbent replacement cycle, and soaring maintenance costs caused by sandstorms and rainwater intrusion. At the same time, it avoids engineering hazards such as pipeline blockage, structural corrosion, and increased equipment failure rate, ensuring that the DAC device can operate continuously, stably, economically, and reliably for a long time.

[0061] To make the purpose, technical solution and advantages of this application clearer, the implementation method will be described in detail below in conjunction with the specific structure and working process of the device of this utility model.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a rain lintel 1 with an adjustable opening angle, including a mesh plate 11, multiple rain lintel units, and a linear drive mechanism 13.

[0063] The mesh panel 11 has multiple continuous air inlet zones.

[0064] Each rain lintel unit is located on the air intake side of its corresponding air intake area. Each rain lintel unit includes multiple stacked baffles 121 and a first connecting rod 122. The end of each baffle 121 near the air intake area is rotatably connected to the mesh plate 11, and the end away from the air intake area is rotatably connected to the first connecting rod 122. An air intake channel is formed between two adjacent baffles 121.

[0065] The linear drive mechanism 13 is used to drive the first link 122 of each rain lint unit to move, so as to drive the baffle 121 of each rain lint unit to rotate. Each baffle 121 can be rotated to sequentially splice together to block the air inlet area, and can be rotated to make the air inlet channel deliver air to the mesh plate 11 at a predetermined angle.

[0066] This invention provides a rain lintel 1 with an adjustable opening angle. A mesh plate 11 allows airflow to pass through; for example, when applied to the adsorption of gases such as carbon dioxide, it allows a mixed gas containing the adsorbed gas to pass through. The mesh plate 11 is divided into multiple air inlet zones, allowing the mixed air to enter each zone, be filtered by the mesh plate 11, and then be sent to its corresponding adsorption structure. The adsorption structure can be an existing adsorption structure for various gases, such as an adsorption bed. Each air inlet zone has a corresponding rain lintel unit, which consists of multiple continuously arranged baffles 121 and a first connecting rod 122 connecting the baffles 121. The first connecting rod 122 drives each baffle 121 to rotate together. The end of the baffle 121 closest to the air inlet zone rotates around a fixed axis, while the end furthest from the air inlet zone moves closer to or further away from the mesh plate 11. Air inlet channels are formed between adjacent baffles 121. These multiple air inlet channels divert the airflow entering each air inlet zone and allow adjustment of the direction of the airflow delivered through the air inlet channels.

[0067] The adjustable rain lintel 1 provided by this utility model, in practical applications, under conditions of no sandstorms and no rainfall, such as... Figure 1 and Figure 2 As shown, the linear drive mechanism 13 drives the first connecting rod 122 to rotate each baffle 121, maintaining the air inlet channel at a preset opening angle, and delivering airflow in a set direction to the mesh plate 11 through the air inlet channel to meet the airflow requirements of the gas adsorption operation on the outlet side of the mesh plate 11; in severe conditions such as sandstorms or rain, such as Figure 3 As shown, the linear drive mechanism 13 drives each baffle 121 to rotate and close through the first connecting rod 122, so that the air inlet channel is completely closed. The baffles 121 overlap each other to form an overall closed structure, which completely blocks the air inlet side of the mesh plate 11, effectively preventing sand and rainwater from entering the interior, and has reliable rainproof and sand and dustproof protection effects.

[0068] The mesh panel 11 primarily serves to prevent insect infestation. The number of air inlet zones in the mesh panel 11 can be flexibly set according to the actual application scenario, generally determined by the number of adsorption structures arranged on the air outlet side of the mesh panel 11. For example, one corresponding air inlet zone can be set for each adsorption structure to prevent insects from entering the adsorption structure with the airflow. For instance, in this embodiment, the number of air inlet zones in the mesh panel 11 is set to six.

[0069] The air inlet zones in the mesh panel 11 are arranged continuously along the same direction. For example, they are arranged continuously along the length of the mesh panel 11. In actual operation of the adjustable-angle rain lintel 1 provided by this utility model, the air inlet zones are arranged horizontally. The air inlet zones in the mesh panel 11 can be separated by partitions or the like, or they can be directly connected into a whole area without gaps. For example, in this embodiment, the mesh panel 11 is a single piece of wire mesh.

[0070] The number of air inlet zones in the mesh panel 11 is the same as the number of rain lint units, and their positions correspond one-to-one. For example, the number of rain lint units is also set to six, namely rain lint units 12a, 12b, 12c, 12d, 12e, and 12f.

[0071] In some embodiments, the continuous arrangement direction of each air inlet zone is perpendicular to the continuous arrangement direction of each baffle 121 in the rain lint unit. For example, each air inlet zone in the mesh panel 11 is continuously arranged along the length direction of the mesh panel 11, while each baffle 121 in the rain lint unit is continuously arranged along the width direction of the mesh panel 11.

[0072] like Figure 5 As shown, the number of baffles 121 in each rain lintel unit can be flexibly set according to the area of ​​the air inlet area, as long as the area of ​​the area formed by the sequential splicing of each baffle 121 is the same as the area of ​​the air inlet area. For example, in this embodiment, the number of baffles 121 in each rain lintel unit is six, namely baffles 121a, 121b, 121c, 121d, and 121e.

[0073] Considering that the air inlet of the adsorption structure arranged on the air outlet side of the mesh plate 11 is generally rectangular, and the shape of the air inlet area matches that of the air inlet, the longitudinal section of the air inlet area is rectangular, and the baffle 121 is a rectangular plate with one side equal to one side of the rectangle. In this way, the baffles 121 can be spliced ​​together to completely block the air inlet area.

[0074] like Figure 4 and Figure 6 As shown, in some embodiments, in each rain lintel unit, the adjacent edges of two adjacent baffles 121 have a cylindrical arc edge 1211 at the lower edge of the upper baffle 121c and an inclined side 1212 at the upper edge of the lower baffle 121d. When the air inlet channel is closed, the arc edge 1211 and the inclined side 1212 are in contact. The diameter of the arc surface is approximately the same as the thickness of the baffle 121, and the inclined side 1212 is formed by bending inward from the edge of the upper surface of the baffle 121 near the air inlet area.

[0075] It should be noted that when the two adjacent baffles 121 rotate, the arc edge 1211 and the inclined edge 1212 cooperate. On the one hand, when the two adjacent baffles 121 rotate to contact and splice, the arc edge 1211 of the lower edge of the upper baffle 121C blocks the outside of the inclined edge 1212 of the upper edge of the lower baffle 121d, forming a partial overlap, which avoids gaps at the splice of the two adjacent baffles 121 and more effectively prevents sand and rainwater from entering the interior. On the other hand, it avoids interference between the lower edge of the upper baffle 121 and the upper edge of the lower baffle 121 when the two adjacent baffles 121 rotate to contact and splice or separate from contact and splice, thus preventing relative movement.

[0076] like Figure 5As shown, a storage groove 111 is provided at the edge of the air intake area. When each air intake channel of each rain lintel unit is closed, each baffle 121 rotates to be accommodated in the storage groove 111 and fills the storage groove 111 completely. The storage groove 111 is formed by a surrounding plate around the air intake area. The depth of the storage groove 111 is equal to or slightly greater than the thickness of the baffle 121. When the baffles 121 are spliced ​​in sequence, the side of each baffle 121 near the mesh plate 11 remains in contact with the mesh plate 11, and all the baffles 121 are completely laid flat in the storage groove 111, filling the storage groove 111 completely and forming a complete shield for the air intake side of the air intake area, further improving the ability to block sand and rainwater from entering.

[0077] To improve the air intake efficiency of the adsorption structure arranged on the air outlet side of the mesh plate 11 and reduce airflow resistance, airflow in a predetermined direction needs to be input into the adsorption structure. Based on the real-time external wind direction on the air inlet side, the linear drive mechanism 13 drives the first connecting rod 122 to rotate each baffle 121, flexibly adjusting the air inlet angle of the air inlet channel to maintain a preset opening angle. For example, the predetermined angle is the angle α between the air inlet channel and the mesh plate 11, where α is 70° to 90°. This angle meets the air intake requirements of the adsorption structure arranged on the air outlet side of the mesh plate 11, significantly reducing airflow resistance, improving carbon dioxide adsorption efficiency, reducing system operating energy consumption, and thus lowering the overall equipment maintenance cost.

[0078] like Figure 5 As shown, each rain lintel unit also includes a second connecting rod 123. The two sides of each baffle 121 are rotatably connected to the first connecting rod 122 and the second connecting rod 123, respectively. The two apex angles of the baffle 121 near the air inlet area are rotatably connected to the mesh plate 11, and the two apex angles away from the air inlet area are rotatably connected to the first connecting rod 122 and the second connecting rod 123, respectively. The first connecting rod 122 and the second connecting rod 123 are both arranged parallel to the mesh plate 11, and both are rotatably connected to each baffle 121, allowing for more stable rotation of each baffle 121.

[0079] In some embodiments, any two adjacent rain gutter units are fixedly connected by adjacent first links 122 and second links 123. Specifically, the adjacent first links 122 and second links 123 of any two adjacent rain gutter units are fixedly connected, so that when the linear drive mechanism 13 drives each first link 122 to move, all rain gutter units move synchronously.

[0080] Furthermore, the linear drive mechanism 13 includes at least one electric cylinder, each of which is connected to the first connecting rod 122 of at least one of the rain gutter units to drive all the rain gutter units to move. When any two adjacent rain gutter units are fixedly connected, it is not necessary to arrange an electric cylinder for each rain gutter unit for individual drive. Only a few electric cylinders are needed to drive the first connecting rod 122 of some of the rain gutter units to move, thereby driving all the rain gutter units to move synchronously. As shown in the figure, for example, there are three electric cylinders, which are evenly spaced along the arrangement direction of all the rain gutter units. The output end of each electric cylinder is connected to the first connecting rod 122 of a rain gutter unit. In this way, the three electric cylinders drive the first connecting rod 122 to move synchronously. When the first connecting rod 122 moves closer to or further away from the mesh plate 11, it drives the baffle 121 to rotate.

[0081] In addition, such as Figure 7 and Figure 8 As shown, an embodiment of this utility model also provides a carbon dioxide adsorption box 2, including a box body 21 and a rain lintel 1 with an adjustable opening angle as described above.

[0082] The box 21 is equipped with multiple adsorption beds.

[0083] An adjustable rain lintel 1 is installed on one side of the housing 21, and the air inlet side of each adsorption bed is set in correspondence with the air inlet area of ​​the mesh plate 11.

[0084] Specifically, the number of adsorption bed groups inside the housing 21 is the same as the number of air inlet zones on the mesh plate 11, and their positions correspond one-to-one. For example, the number of adsorption bed groups is also set to six.

[0085] Those skilled in the art should know that each adsorption bed is formed by a Z-shaped stacking of multiple individual adsorption beds. Adsorption beds are common carbon dioxide capture devices. The adsorption beds are generally filled with solid adsorbents, which can be one or more of zeolite molecular sieves, activated carbon, MOF materials, amine functionalized materials, etc. The selective adsorption characteristics of solid adsorbents enable the efficient separation and recovery of carbon dioxide in the mixed gas.

[0086] The air inlet side of the housing 21 is open, and the mesh plate 11 is installed on the air inlet side of the housing 21 and covers the housing 21, so that each rain lint unit is arranged outside a set of adsorption beds.

[0087] The linear drive mechanism 13 selects three electric cylinders, which are evenly distributed along the length of the housing 21. The cylinder ends of the three electric cylinders are rotatably fixed to the bottom of the housing 21. The output ends of the three electric cylinders are distributed and connected to the first connecting rods 122 of the three rain lint units. Thus, the extension and retraction of the output ends of the three electric cylinders synchronously drive the first connecting rods 122 to move.

[0088] A mixed gas containing carbon dioxide flows into the outside of the housing 21 through the air inlet channel between adjacent baffles 121. After being filtered by the mesh plate 11, the airflow enters the adsorption bed. The solid adsorbent adsorbs the carbon dioxide in the mixed gas, while the remaining residual gas is discharged from the side of the housing 21 opposite to the rain lintel 1 with an adjustable opening angle, thus achieving continuous carbon dioxide adsorption.

[0089] This utility model embodiment also provides a carbon dioxide adsorption box 2 placed outdoors. Under normal operating conditions without sandstorms or rainfall, the air inlet areas of the mesh plate 11 are directionally delivered to the corresponding adsorption bed air inlet side through the air inlet channel, so that the air enters the adsorption bed in the optimal flow direction, effectively improving the adsorption efficiency of the adsorption bed for carbon dioxide, while reducing the energy consumption of the equipment. Under severe operating conditions of sandstorms or rainfall, the first connecting rod 122 is driven by the linear drive mechanism 13 to drive the baffles 121 to rotate synchronously, realizing the adaptive adjustment of the working posture of each rain lintel unit. This can effectively block sandstorms and rainwater from entering the box 21 and the adsorption bed with the airflow, fundamentally solving the problems of low decarbonization efficiency, increased operating energy consumption, shortened adsorbent replacement cycle, and soaring maintenance costs caused by sandstorms and rainwater intrusion. At the same time, it avoids engineering hazards such as pipeline blockage, structural corrosion, and increased equipment failure rate, ensuring that the DAC device can operate continuously, stably, economically, and reliably for a long time.

[0090] It should be noted that the carbon dioxide adsorption box 2 of this utility model is mainly used to capture rarefied carbon dioxide in the air. Specific scenarios include, but are not limited to, carbon dioxide resource utilization and carbon dioxide sequestration. Carbon dioxide resource utilization mainly involves collecting, compressing, and drying high-concentration carbon dioxide for resource utilization, such as synthesizing methanol, aviation fuel, and other fuels. Carbon dioxide sequestration involves capturing and compressing carbon dioxide and transporting it to specific locations such as geological or marine sites for long-term isolation, rather than releasing it into the atmosphere, in order to achieve carbon emission reduction.

[0091] For example, the device embodiments described above are merely illustrative. For instance, the division of units is only a logical functional division. In actual implementation, there may be other division methods. For example, multiple units or components may be combined or integrated into another device, or some features may be ignored or not executed.

[0092] The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.
