[0002] This application claims priority based on Japanese Patent Application No. 2022-111755, filed on July 12, 2022, the contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to recycling devices. Background Technology

[0004] To reduce carbon dioxide (CO2), methods for recovering carbon dioxide contained in the air using a recovery device (DAC (direct air capture) device) are known. In such recovery devices, there are recovery devices with cover members at both the intake and exhaust ports. For example, the cover member at the intake port is located inside the intake port and moves to a closed position and an open position by operating a multi-joint arm. Similarly, the cover member at the exhaust port is also located inside the exhaust port and moves via a multi-joint arm (see, for example, U.S. Patent No. 10,232,305).

[0005] According to this recovery device, during the carbon dioxide removal process, the cover member can be positioned in the closed position to block the intake and exhaust ports. This reduces the volume of the enclosed space within the recovery device, thereby decreasing pressure and improving the carbon dioxide removal efficiency. Hereinafter, the intake and exhaust ports will sometimes be referred to as openings. Summary of the Invention

[0006] However, the recycling device in U.S. Patent No. 10,232,305 requires a multi-jointed arm inside the opening to move the cover member to the closed and open positions, which complicates the structure. Furthermore, the cover member and the multi-jointed arm being located inside the opening cause pressure loss at the opening due to the cover member and the multi-jointed arm.

[0007] The present invention provides a recycling device that can move the cover member through a simple structure and can reduce pressure loss at the opening.

[0008] (1) The recovery device of the present invention is a recovery device for recovering specific molecules from the atmosphere (e.g., recovery device 10 of the embodiment), comprising: a frame (e.g., frame 12 of the embodiment), which is disposed inside by a solid adsorbent (e.g., solid adsorbent 35 of the embodiment) for adsorbing the specific molecules; at least one pair of openings (e.g., air inlet 41 and air outlet 55 of the embodiment) for allowing air to circulate into the interior of the frame; and a blower (e.g., blower 19 of the embodiment) disposed in at least one of the openings (e.g., air outlet 55 of the embodiment), wherein the blower is mounted by a hinge (e.g., fourth hinge shaft 58 of the embodiment) so as to be rotatable from the opening in one direction and separate from the opening, and a cover member (e.g., second cover member 18 of the embodiment) is provided in the opening, the cover member being mounted by a hinge (e.g., third hinge shaft 57 of the embodiment) so as to be rotatable from the opening in another direction relative to the first direction and separate from the opening.

[0009] According to this structure, the cover member is hinged to the opening so that it can be detached from the opening. Thus, the cover member can be moved between an open position and a closed position with a simple structure, wherein the open position is the position where the cover member is detached from the opening to open the opening, and the closed position is the position where the cover member returns to the opening to close the opening.

[0010] Furthermore, the cover member can be separated from the opening. Therefore, with the opening open and the cover member separated from the opening, the cover member can be positioned outside the opening. That is, the cover member can be positioned outside the flow path in the recovery device. This reduces pressure loss at the opening when recovering (specifically, adsorbing) specific molecules from the atmosphere. Consequently, the recovery device can efficiently recover and reduce carbon dioxide contained in the atmosphere.

[0011] Furthermore, the cover member is hinged to the opening, allowing it to rotate in the opposite direction (i.e., the opposite side of the blower) and detach from the opening. Thus, with the cover member detached from the opening, the blower can be moved to the location where the cover member was placed. In other words, the blower and cover member can be swapped at the opening.

[0012] Therefore, the distance from the frame containing the solid adsorbent to the blower in the recovery device can be shortened. Consequently, the pressure drop generated at the opening can be reduced more appropriately when recovering (e.g., adsorbing) specific molecules from the atmosphere.

[0013] (2) In the above scheme, the opening may be an air intake port (e.g., air intake port 41 in the embodiment) for drawing air into the interior of the frame and an exhaust port (e.g., exhaust port 55 in the embodiment) for discharging air out of the interior of the frame, and the blower is disposed on the exhaust port side.

[0014] According to this structure, by placing the blower on the exhaust port side, a negative pressure can be created inside the frame when recovering (specifically, adsorbing) specific molecules from the atmosphere. This negative pressure ensures a good seal between the frame and the blower. Consequently, the load on the hinges mounting the blower is reduced, and the amount of air leaking from the gap between the frame and the blower is minimized. Furthermore, the mounting device for securing the blower to the exhaust port side is simplified.

[0015] (3) In the above scheme, a rectifier (e.g., rectifier 16 in the embodiment) and another cover member (e.g., first cover member 15 in the embodiment) are provided on the intake port side. The rectifier is mounted by a hinge (e.g., second hinge shaft 44 in the embodiment) so that it can rotate from the intake port in one direction and separate from the intake port. The other cover member is mounted by a hinge (e.g., first hinge shaft 43 in the embodiment) so that it can rotate from the intake port in another direction relative to the first direction and separate from the intake port.

[0016] According to this structure, another cover member is hinged to the air intake, allowing it to be separated from the air intake. Thus, the other cover member can be moved between an open position and a closed position using a simple structure. The open position is where the other cover member is separated from the air intake, opening the air intake, while the closed position is where the other cover member returns to the air intake, closing it.

[0017] Furthermore, the other cover member can be separated from the intake port. Thus, with the other cover member separated from the intake port and the opening open, the other cover member can be positioned outside the intake port. That is, in the recovery device, the other cover member can be positioned outside the flow path. Therefore, when recovering (specifically, adsorbing) specific molecules from the atmosphere, the pressure drop generated at the exhaust port can be reduced.

[0018] Furthermore, another cover component is hinged to the air intake, allowing it to rotate in the opposite direction (i.e., the opposite side of the rectifier) ​​and separate from the air intake. Thus, with the other cover component separated from the air intake, the rectifier can be moved to the location where the other cover component was previously positioned. In other words, the rectifier and the other cover component can be interchanged at the air intake.

[0019] Therefore, the distance from the frame containing the solid adsorbent to the rectifier can be shortened in the recovery device. Consequently, the pressure drop generated at the rectifier can be reduced more appropriately when recovering (e.g., adsorbing) specific molecules from the atmosphere.

[0020] (4) In the above scheme, the opening may be provided on the side of the frame, and the hinges of the blower and the cover member are installed with their axes facing the vertical direction so that the blower and the cover member can rotate to the side of the opening.

[0021] According to this structure, the hinge is configured with its axis pointing vertically, and a blower and cover component are mounted on the hinge. This allows the blower and cover component to rotate horizontally to the side about the hinge axis. Therefore, compared to, for example, rotating the blower and cover component in an up-down direction, the gravitational load when rotating the blower and cover component laterally about the hinge axis can be reduced. Consequently, the blower and cover component can be rotated laterally with minimal force.

[0022] (5) In the above scheme, the recycling device may also be equipped with a motor (for example, the first electric motor 81, the second electric motor 83, the third electric motor 85, and the fourth electric motor 87 in the embodiment), and the hinge is controlled to rotate by the motor.

[0023] Based on this structure, the rotation of the hinge is controlled by a motor. This allows for efficient management of the motor torque (load) when, for example, the cover member or blower comes into contact with the frame. Consequently, proper movement is ensured when moving the cover member or blower.

[0024] According to the present invention, the cover member can be moved with a simple structure, and pressure loss at the opening can be reduced. Attached Figure Description

[0034] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0035] <Recycling Device>

[0036] Figure 1 This is a schematic diagram showing the recovery device of the embodiment set to a carbon dioxide adsorption state. Figure 2 This is a schematic diagram showing the recovery device of the embodiment set to a state where carbon dioxide is removed. Figure 3 Observing from III towards the viewing direction Figure 2 A side view of the recycling device.

[0037] like Figures 1-3 As shown, the recovery device 10 uses a solid adsorbent to adsorb carbon dioxide (specific molecules) contained in the air and removes the adsorbed carbon dioxide from the solid adsorbent, thereby recovering carbon dioxide contained in the air. Specifically, the recovery device 10 includes a frame 12, an adsorption and removal module 13, an air intake section 14, a first cover member (another cover member) 15, a rectifier 16, an exhaust section 17, a second cover member (a cover member) 18, a blower 19, a drive unit 20, a negative pressure pump 21, and a high-temperature negative pressure steam supply section 22.

[0038] It should be noted that the frame 12, the intake section 14, and the exhaust section 17 are arranged coaxially. Hereinafter, the axis 30 of the frame 12, the intake section 14, and the exhaust section 17 will sometimes be referred to as "the axis 30 of the frame 12". In addition, the radial direction centered on the axis 30 of the frame 12 will sometimes be abbreviated as "radial". Furthermore, in the following description, the intake section 14 side of the recovery device 10 will be referred to as the "upstream side", and the exhaust section 17 side of the recovery device 10 will be referred to as the "downstream side".

[0039] <Frame, Adsorption / Desorption Module>

[0040] The frame 12 is, for example, formed as a hollow cylinder. An adsorption-desorption module 13 is installed inside the frame 12. The adsorption-desorption module 13 includes, for example, a solid adsorbent 35 and a heat exchanger 36. The solid adsorbent 35 is disposed inside the frame 12 to adsorb, for example, carbon dioxide (specific molecules) contained in atmospheric air.

[0041] A heat exchanger 36 is disposed in the frame 12, and a fluid (heat exchange medium) for heat exchange is introduced to the solid adsorbent 35 side, thereby heating the solid adsorbent 35 through heat exchange. By heating the solid adsorbent 35 through heat exchange, carbon dioxide contained in the air can be effectively adsorbed onto the solid adsorbent 35.

[0042] <Inhalation Section>

[0043] The air intake 14 is coaxially mounted on the upstream side of the frame 12. The air intake 14 is formed, for example, a hollow cylindrical shape, and has an air intake 41 (opening). The air intake 41 communicates with the interior of the frame 12 on the upstream side, allowing air to be drawn into (flow through) the interior of the frame 12. Furthermore, the air intake 14 includes, for example, a first sealing element (O-ring) 42, a first hinge shaft (hinge) 43, and a second hinge shaft (hinge) 44.

[0044] The first seal 42 is disposed on the contact surface 14a of the air intake 14. The first seal 42 is located radially outside the air intake 41 and is formed in an annular shape along the air intake 41.

[0045] The first hinge shaft 43 is located radially outside the air intake 41 in the air intake section 14, intersecting the axis 30 of the frame 12, and the axis (not shown) of the first hinge shaft 43 is mounted in the vertical direction. The first hinge shaft 43 is, for example, fixed coaxially with the output shaft (not shown) of the first reducer 82 described later. The first cover member 15, described later, is provided on the first hinge shaft 43. That is, the first cover member 15 is provided in the air intake section 14 via the first hinge shaft 43 and is disposed on the upstream side (air intake 41 side) of the air intake 41.

[0046] The second hinge shaft 44 is disposed in the intake section 14 at a circumferential distance of 180° from the first hinge shaft 43, on the opposite side of the first hinge shaft 43. The second hinge shaft 44, like the first hinge shaft 43, is located radially outside the intake port 41, intersecting the axis 30 of the frame 12, and the axis of the second hinge shaft 44 (not shown) is mounted vertically. The second hinge shaft 44 is, for example, coaxially fixed to the output shaft (not shown) of the second reducer 84, which will be described later. The rectifier 16, described later, is supported by the second hinge shaft 44. That is, the rectifier 16 is disposed in the intake section 14 via the second hinge shaft 44 and is located upstream of the intake port 41 (intake port 41 side).

[0047] <First Cover Component>

[0048] The first cover member 15 has a cover body 47 and a base 48. The cover body 47 is formed in a generally disc-shaped manner so as to cover the air intake 41 of the air intake portion 14 from the contact surface 14a side. Moreover, the cover body 47 is formed to be larger in diameter than the first sealing member 42 in the radial direction. The base 48 is provided on the radially outer side of the cover body 47.

[0049] The base 48 is fixed relative to the first hinge axis 43 so as not to rotate in the circumferential direction. That is, the first cover member 15 is mounted such that the first hinge axis 43 is rotated by the first electric motor 81 described later, thereby enabling the first cover member 15 to rotate between the open position P1 and the closed position P2 via the first hinge axis 43.

[0050] Here, the axis of the first hinge shaft 43 is mounted vertically. Therefore, the first cover member 15 can rotate horizontally to the side of the air intake 41 about the first hinge shaft 43. Additionally, a limiting member (not shown) is provided in the open position P1 for positioning the first cover member 15 in the open position P1. A contact surface 14a is provided in the closed position P2 for positioning the first cover member 15 in the closed position P2.

[0051] When the first cover member 15 is positioned in the open position P1, which allows it to separate from the air intake 41, it is configured to open the air intake 41. Furthermore, when the first cover member 15 is positioned in the closed position P2, which contacts the contact surface 14a of the air intake section 14, it is configured to contact the first seal member 42 and close the air intake 41.

[0052] <Rectifier>

[0053] The rectifier 16 includes a frame body 51, a base 52, and a rectifier section (not shown). The frame body 51 is formed in a generally annular shape to cover the contact surface 14a of the intake section 14. Furthermore, the outer periphery of the frame body 51 is formed to be larger than the diameter of the first seal 42 in the radial direction, and the inner periphery is formed to be the same as the diameter of the intake port 41.

[0054] Additionally, a base 52 is provided on the radially outer side of the frame 51. The base 52 is fixed relative to the second hinge axis 44 so that it cannot rotate in the circumferential direction. That is, the rectifier 16 is mounted such that the second hinge axis 44 is rotated by the second electric motor 83 described later, thereby enabling the rectifier 16 to rotate between the separation position P3 and the rectification position P4 via the second hinge axis 44.

[0055] Here, the axis of the second hinge shaft 44 is mounted in the vertical direction. As a result, the rectifier 16 can rotate horizontally to the side of the intake port 41 about the second hinge shaft 44.

[0056] Additionally, a movement limiting member (not shown) is provided at the separation position P3 for positioning the rectifier 16 at the separation position P3. A contact surface 14a is provided at the rectification position P4 for positioning the rectifier 16 at the rectification position P4.

[0057] When the rectifier 16 is positioned in the separation position P3, which allows it to separate from the intake port 41, the intake port 41 is left open. Furthermore, when the frame body 51 is positioned in the rectification position P4, which contacts the contact surface 14a of the intake section 14, the rectifier 16 contacts the first seal 42, thus positioning the rectification section upstream of the intake port 41.

[0058] An air rectifier (not shown) is provided inside the frame body 51. The air rectifier has the following function: when the frame body 51 is positioned at the air rectifier position P4, which is in contact with the contact surface 14a of the air intake 14, it guides the air drawn in from the atmosphere to the entire area of ​​the air intake 41 (i.e., the solid adsorbent 35) at a stable flow rate.

[0059] <Exhaust Section>

[0060] The exhaust section 17 is coaxially mounted on the downstream side of the frame 12. The exhaust section 17 is formed, for example, as a hollow cylinder and has an exhaust port 55 (one of at least a pair of openings). The exhaust port 55 is an opening that communicates with the interior of the frame 12 on the downstream side to exhaust air from the interior of the frame 12, thereby allowing air to flow from the intake port 41 into the interior of the frame 12. The exhaust section 17 includes, for example, a second seal (O-ring) 56, a third hinge pin (hinge) 57, and a fourth hinge pin (hinge) 58.

[0061] The second seal 56 is disposed on the contact surface 17a of the exhaust portion 17. The second seal 56 is located radially outside the exhaust port 55 and is formed in an annular shape along the exhaust port 55.

[0062] The third hinge shaft 57 is located radially outside the exhaust port 55 in the exhaust section 17, intersecting the axis 30 of the frame 12, and the axis of the third hinge shaft 57 (not shown) is mounted in the vertical direction. The third hinge shaft 57 is, for example, fixed coaxially with the output shaft (not shown) of the third reducer 86 described later. The second cover member 18, described later, is provided on the third hinge shaft 57. That is, the second cover member 18 is provided in the exhaust section 17 via the third hinge shaft 57 and is disposed on the downstream side (exhaust port 55 side) of the exhaust port 55.

[0063] The fourth hinge shaft 58 is disposed in the exhaust section 17 at a circumferential distance of 180° from the third hinge shaft 57, opposite to the third hinge shaft 57. The fourth hinge shaft 58, like the third hinge shaft 57, is located radially outside the exhaust port 55, intersecting the axis 30 of the frame 12, and the axis of the fourth hinge shaft 58 (not shown) is mounted vertically. The fourth hinge shaft 58 is, for example, coaxially fixed to the output shaft (not shown) of the fourth reducer 88 described later. The blower 19, described later, is supported on the fourth hinge shaft 58. That is, the blower 19 is disposed in the exhaust section 17 via the fourth hinge shaft 58 and is located downstream of the exhaust port 55 (exhaust port 55 side).

[0064] <Second cover component>

[0065] The second cover member 18 is formed in a manner substantially similar to the first cover member 15, having a cover body 61 and a base 62. The cover body 61 is formed in a generally disc-shaped manner so as to cover the exhaust port 55 of the exhaust portion 17 from the contact surface 17a side. Moreover, the cover body 61 is formed to be larger in diameter than the second seal member 56 in the radial direction.

[0066] A base 62 is provided on the radially outer side of the cover body 61. The base 62 is fixed relative to the third hinge axis 57 so as not to rotate in the circumferential direction. That is, the second cover member 18 is mounted such that the third hinge axis 57 is rotated by the third electric motor 85 described later, thereby enabling the second cover member 18 to rotate between the open position P5 and the closed position P6 via the third hinge axis 57.

[0067] When the second cover member 18 is positioned in the open position P5, which allows it to separate from the exhaust port 55, it is configured to leave the exhaust port 55 open. Furthermore, when the second cover member 18 is positioned in the closed position P6, which contacts the contact surface 17a of the exhaust section 17, it is configured to contact the second seal member 56 and close the exhaust port 55.

[0068] Here, the axis of the third hinge shaft 57 is mounted in the vertical direction. As a result, the second cover member 18 can rotate horizontally to the side of the air intake 41 about the third hinge shaft 57.

[0069] Additionally, a movement limiting member (not shown) is provided at the open position P5 for positioning the second cover member 18 at the open position P5. A contact surface 17a is provided at the closed position P6 for positioning the second cover member 18 at the closed position P6.

[0070] <Blower>

[0071] The blower 19 includes a frame body 65, a base 66, and an inlet fan 67. The frame body 65 is formed in a generally annular shape to cover the contact surface 17a of the exhaust section 17. Moreover, the outer periphery of the frame body 65 is formed to be larger than the diameter of the second seal 56 in the radial direction, and the inner periphery is formed to be the same as the diameter of the exhaust port 55.

[0072] Additionally, a base 66 is provided on the radially outer side of the frame 65. The base 66 is fixed relative to the fourth hinge axis 58 and cannot rotate in the circumferential direction. That is, the blower 19 is mounted such that the fourth hinge axis 58 is rotated by the fourth electric motor 87 described later, thereby enabling the blower 19 to rotate between the separated position P7 and the introduced position P8 via the fourth hinge axis 58.

[0073] Here, the axis of the fourth hinge shaft 58 is mounted in the vertical direction. As a result, the blower 19 can rotate horizontally to the side of the exhaust port 55 about the fourth hinge shaft 58.

[0074] Additionally, a movement limiting member (not shown) is provided at the separation position P7 for positioning the blower 19 at the separation position P7. A contact surface 17a is provided at the inlet position P8 for positioning the blower 19 at the inlet position P8.

[0075] When the blower 19 is positioned at the separation position P7, which allows it to separate from the exhaust port 55, the exhaust port 55 is left open. Furthermore, when the frame 65 is positioned at the inlet position P8, which contacts the contact surface 17a of the exhaust section 17, the blower 19 contacts the second seal 56, and the inlet fan 67 is positioned downstream of the exhaust port 55.

[0076] An inlet fan 67 is provided inside the frame 65. The inlet fan 67 is driven when the frame 65 is positioned in the inlet position P8, which is in contact with the contact surface 17a of the exhaust section 17. As a result, air inside the frame 12 is discharged from the exhaust port 55, and air flows (introduces) from the intake port 41 into the interior of the frame 12 (i.e., the solid adsorbent 35).

[0077] <Driver Unit>

[0078] The drive unit 20 is a unit that enables the first cover member 15, the rectifier 16, the second cover member 18, and the blower 19 to operate respectively, and enables the first cover member 15, the rectifier 16, the second cover member 18, and the blower 19 to operate in a coordinated manner. The drive unit 20 includes a first drive unit 71, a second drive unit 72, a third drive unit 73, and a fourth drive unit 74.

[0079] The first drive unit 71 is disposed in the air intake 14 near the first hinge shaft 43. The first drive unit 71 includes, for example, a first electric motor (motor) 81 and a first reducer 82. In the first reducer 82, for example, an output shaft (not shown) is fixed coaxially with the first hinge shaft 43. The first drive unit 71 drives the first electric motor 81, which in turn rotates the first hinge shaft 43 via the first reducer 82. That is, the rotation of the first hinge shaft 43 is controlled by the first electric motor 81. This reliably allows the first cover member 15 to open and close between the open position P1 and the closed position P2.

[0080] Furthermore, the first drive unit 71 precisely controls the opening and closing angle of the first cover member 15 using a rotation angle sensor (not shown). Additionally, the first drive unit 71 causes the first cover member 15 to abut against the limiting member in the open position P1 and against the contact surface 14a of the suction section 14 in the closed position P2. In this state, the closed position P1 and the open position P2 can be detected without sensors by detecting a sharp increase in the current value.

[0081] Thus, by forming a dual system under the control of the first drive unit 71, the stable operation of the first cover member 15 can be ensured.

[0082] The second drive unit 72 is disposed in the intake section 14 near the second hinge shaft 44. The second drive unit 72 includes, for example, a second electric motor (motor) 83 and a second reducer 84. The second drive unit 72 is configured in the same way as the first drive unit 71, so detailed description is omitted.

[0083] The third drive unit 73 is disposed in the exhaust section 17 near the third hinge shaft 57. The third drive unit 73 includes, for example, a third electric motor (motor) 85 and a third reducer 86. The third drive unit 73 is configured in the same way as the first drive unit 71, so detailed description is omitted.

[0084] The fourth drive unit 74 is disposed in the exhaust section 17 near the fourth hinge shaft 58. The fourth drive unit 74 includes, for example, a fourth electric motor (motor) 87 and a fourth reducer 88. The fourth drive unit 74 is configured in the same way as the first drive unit 71, so detailed description is omitted.

[0085] <Negative pressure pump>

[0086] The negative pressure pump 21 is connected to the interior of the frame 12 via the pump suction pipe 91. The negative pressure pump 21 is driven while the interior of the frame 12 is sealed by the first cover member 15 and the second cover member 18, thereby maintaining a negative pressure inside the frame 12. By maintaining a negative pressure inside the frame 12, carbon dioxide adsorbed on the solid adsorbent 35 can be removed from the solid adsorbent 35. The removed carbon dioxide is guided from the interior of the frame 12 towards the negative pressure pump 21 for recovery.

[0087] Here, a first on / off valve 93 is installed in the frame 12. By closing the first on / off valve 93, the internal space of the frame 12 is isolated from the atmosphere. Therefore, the negative pressure pump 21 can maintain the internal space of the frame 12 at a negative pressure. Alternatively, by opening the first on / off valve 93, the internal space of the frame 12 is opened to the atmosphere. This releases the negative pressure from the internal space of the frame 12. In other words, the first on / off valve 93 is a negative pressure on / off valve that releases the negative pressure from the internal space of the frame 12.

[0088] <High-Temperature Negative-Pressure Steam Supply Department>

[0089] The high-temperature negative pressure steam supply unit 22 is connected to the interior of the frame 12 via a steam supply pipe 95. A second on / off valve 96 is installed midway through the steam supply pipe 95. The high-temperature negative pressure steam supply unit 22 is in a non-connected state relative to the interior of the frame 12 by closing the second on / off valve 96, and is in a connected state relative to the interior of the frame 12 by opening the second on / off valve 96.

[0090] The high-temperature negative pressure steam supply unit 22 opens the second on / off valve 96 in the state of being sealed inside the frame 12 by the first cover member 15 and the second cover member 18, thereby allowing superheated steam to flow into the interior of the frame 12 through the steam supply pipe 95.

[0091] Therefore, by allowing superheated steam to circulate into the interior of the frame 12 via the steam supply pipe 95, the partial pressure of carbon dioxide can be reduced. This allows carbon dioxide adsorbed on the solid adsorbent 35 to be appropriately removed from the solid adsorbent 35 while maintaining a moderate negative pressure level inside the frame 12 generated by the negative pressure pump 21. In other words, by introducing superheated steam into the interior of the frame 12 from the high-temperature negative pressure steam supply section 22, carbon dioxide can be easily removed from the solid adsorbent 35 by the negative pressure pump 21.

[0092] Next, based on Figures 4-9 Let's illustrate an example of recovering carbon dioxide from the air using the recovery device 10. It should be noted that... Figures 4-9The description of the first drive unit 71, the second drive unit 72, the third drive unit 73, and the fourth drive unit 74 that control the first cover component 15, the rectifier 16, the second cover component 18, and the blower 19 is omitted.

[0093] Figure 4 This is a schematic diagram illustrating an example of carbon dioxide being adsorbed onto a solid adsorbent using a recovery device according to an embodiment.

[0094] like Figure 4 As shown, the rectifier 16 is positioned at the rectifier position P4, and the first cover member 15 is positioned at the open position P1. Additionally, the blower 19 is positioned at the inlet position P8, and the second cover member 18 is positioned at the open position P5. Furthermore, the solid adsorbent 35 is heated by the heat exchanger 36. It should be noted that the first on / off valve 93 and the second on / off valve 96 are closed.

[0095] In this state, the inlet fan 67 drives the blower 19. As a result, air inside the frame 12 is discharged from the exhaust port 55 as indicated by arrow A, and air is introduced into the frame 12 from the intake port 41 as indicated by arrow B. The air introduced into the frame 12 circulates within the solid adsorbent 35, whereby carbon dioxide in the air is adsorbed onto the solid adsorbent 35.

[0096] Here, the blower 19 is positioned on the exhaust port 55 side. This drives the inlet fan 67, thereby generating a negative pressure between the inlet fan 67 and the frame 12. This allows the blower 19 to be self-held in a state where it is sealed to the contact surface 17a and the second seal 56 of the exhaust section 17 using this negative pressure.

[0097] Figure 5 This is a schematic diagram illustrating an example of starting the recovery device of the embodiment to a state of carbon dioxide removal.

[0098] like Figure 5 As shown, after carbon dioxide is adsorbed onto the solid adsorbent 35, the inlet fan 67 of the blower 19 is stopped. In this state, the rectifier 16 is rotated horizontally to the side in the direction of arrow C (one direction) about the second hinge axis 44 from the rectifier position P4. In addition, the first cover member 15 is rotated horizontally to the side in the direction of arrow D about the first hinge axis 43 from the open position P1.

[0099] Furthermore, the blower 19 is rotated horizontally to the side in the direction of arrow E (one direction) about the fourth hinge axis 58 from the inlet position P8. In addition, the second cover member 18 is rotated horizontally to the side in the direction of arrow F about the third hinge axis 57 from the open position P5.

[0100] Figure 6This is a schematic diagram illustrating an example of how the recovery device of the embodiment continues to operate in a state of carbon dioxide removal.

[0101] like Figure 6 As shown, the rectifier 16 is rotated horizontally to the side in the direction of arrow C from the rectifier position P4 about the second hinge axis 44. Additionally, the first cover member 15 is rotated horizontally to the side in the direction of arrow D from the open position P1 about the first hinge axis 43.

[0102] Furthermore, the blower 19 is rotated horizontally to the side in the direction of arrow E from the lead-in position P8 about the fourth hinge axis 58. In addition, the second cover member 18 is rotated horizontally to the side in the direction of arrow F from the open position P5 about the fourth hinge axis 58.

[0103] Figure 7 This is a schematic diagram illustrating an example of recovering carbon dioxide from a solid adsorbent using a recovery device according to an embodiment.

[0104] like Figure 7 As shown, the rectifier 16 is positioned at the separated position P3, and the first cover member 15 is positioned at the closed position P2. Additionally, the blower 19 is positioned at the separated position P7, and the second cover member 18 is positioned at the closed position P6. Thus, the interior of the frame 12 is sealed by the first cover member 15 and the second cover member 18. Furthermore, the solid adsorbent 35 continues to be heated via the heat exchanger 36.

[0105] In this state, superheated steam is introduced from the high-temperature negative pressure steam supply section 22 into the interior of the frame 12 by opening the second on / off valve 96. Furthermore, the negative pressure pump 21 is activated. By activating the negative pressure pump 21, the interior of the frame 12 is maintained at a negative pressure, causing carbon dioxide adsorbed on the solid adsorbent 35 to detach from the solid adsorbent 35. The detached carbon dioxide is guided from the interior of the frame 12 towards the negative pressure pump 21 for recovery.

[0106] Here, the rectifier 16 is configured to rotate to the separated position P3. Therefore, with the first cover member 15 positioned in the closed position P2, the first cover member 15 can close the intake port 41 when it is close to the frame 12. Furthermore, the blower 19 is configured to rotate to the separated position P7. Therefore, with the second cover member 18 positioned in the closed position P6, the second cover member 18 can close the exhaust port 55 when it is close to the frame 12.

[0107] Therefore, the internal space of the frame 12 sealed by the first cover member 15 and the second cover member 18 can be reduced to a small size. In this way, by reducing the internal space of the frame 12, carbon dioxide can be properly removed from the solid adsorbent 35, and the concentration of carbon dioxide removed from the solid adsorbent 35 can be increased.

[0108] Figure 8 This is a schematic diagram illustrating an example of starting the recovery device of the embodiment into a carbon dioxide adsorption state.

[0109] like Figure 8 As shown, after recovering carbon dioxide from the solid adsorbent 35, the second on / off valve 96 is closed to isolate the high-temperature negative pressure vapor supply section 22 from the internal space of the frame 12. Additionally, the operation of the negative pressure pump 21 is stopped and the first on / off valve 93 is opened, thereby releasing the negative pressure in the internal space of the frame 12.

[0110] In this state, the rectifier 16 is rotated horizontally to the side in the direction of arrow G from the separated position P3 about the second hinge axis 44. In addition, the first cover member 15 is rotated horizontally to the side in the direction of arrow H (another direction) about the first hinge axis 43 from the closed position P2.

[0111] Furthermore, the blower 19 is rotated horizontally to the side in the direction of arrow I from the separated position P7 about the fourth hinge axis 58. In addition, the second cover member 18 is rotated horizontally to the side in the direction of arrow J (another direction) about the fourth hinge axis 58 from the closed position P6.

[0112] Figure 9 This is a schematic diagram illustrating an example of carbon dioxide being adsorbed onto a solid adsorbent using a recovery device according to an embodiment.

[0113] like Figure 9 As shown, the rectifier 16 is positioned at the rectifier position P4, and the first cover member 15 is positioned at the open position P1. Additionally, the blower 19 is positioned at the inlet position P8, and the second cover member 18 is positioned at the open position P5.

[0114] In this state, such as Figure 4 As described, the blower 19 is driven by the intake fan 67. Thus, air inside the frame 12 is discharged from the exhaust port 55 as indicated by arrow K, and air is introduced into the frame 12 from the intake port 41 as indicated by arrow L. The air introduced into the frame 12 circulates within the solid adsorbent 35, thereby causing carbon dioxide in the air to be adsorbed onto the solid adsorbent 35.

[0115] Here, by moving the rectifier 16 toward the position where the first cover member 15 is disposed, the rectifier 16 and the first cover member 15 can be swapped at the intake port 41. In addition, by moving the blower 19 toward the position where the second cover member 18 is disposed, the blower 19 and the second cover member 18 can be swapped at the exhaust port 55.

[0116] This shortens the distance from the frame 12 to the blower 19, and also shortens the distance from the frame 12 to the rectifier 16. This reduces the pressure drop at the intake port 41 and the exhaust port 55, allowing carbon dioxide in the air to be properly adsorbed onto the solid adsorbent 35.

[0117] The following will be done by repeating the process. Figures 4-9 The process described herein enables the continuous recovery of carbon dioxide from the atmosphere via the recovery device 10.

[0118] It should be noted that, in the implementation method, carbon dioxide is used as an example of a specific molecule, but the specific molecule is not limited to carbon dioxide.

[0119] As described above, the recycling device 10 according to the embodiment, such as Figure 1 , Figure 2 As shown, the first cover member 15 is mounted to the air intake 14 via the first hinge shaft 43, allowing the first cover member 15 to separate from the air intake port 41 of the air intake 14. Thus, the first cover member 15 can be moved between an open position P1 and a closed position P2 using a simple structure. The open position P1 is the position where the first cover member 15 separates from the air intake port 41, opening the air intake port, while the closed position P2 is the position where the first cover member 15 returns to the air intake port 41, closing the air intake port 41.

[0120] Furthermore, the second cover member 18 is mounted to the exhaust section 17 via the third hinge shaft 57, allowing the second cover member 18 to be separated from the exhaust port 55 of the exhaust section 17. Thus, the second cover member 18 can be moved between an open position P5 and a closed position P6 with a simple structure. The open position P5 is the position where the second cover member 18 is separated from the exhaust port 55, opening the exhaust port 55, and the closed position P6 is the position where the second cover member 18 returns to the exhaust port 55, closing the exhaust port 55.

[0121] Furthermore, the first cover member 15 can be separated from the air intake port 41. Therefore, with the air intake port 41 open and the first cover member 15 separated from it, the first cover member 15 can be positioned outside the air intake port 41. Additionally, the second cover member 18 can be separated from the exhaust port 55. Therefore, with the exhaust port 55 open and the second cover member 18 separated from it, the second cover member 18 can be positioned outside the exhaust port 55.

[0122] That is, in the recovery device 10, the first cover member 15 and the second cover member 18 can be arranged outside the flow path. As a result, the pressure loss generated at the intake section 14 and the exhaust port 55 can be reduced when recovering carbon dioxide from the atmosphere. Therefore, the recovery device 10 can efficiently recover and reduce the carbon dioxide contained in the atmosphere.

[0123] Furthermore, the second cover member 18 is mounted to the exhaust section 17 via the third hinge shaft 57, so that the second cover member 18 can face the opposite side of the blower 19 along arrow J (see reference). Figure 8 The blower 19 rotates and separates from the exhaust port 55. Therefore, with the second cover member 18 separated from the exhaust port, the blower 19 can be moved to the location where the second cover member 18 was placed. That is, the blower 19 and the second cover member 18 can be swapped at the exhaust port 55, thereby shortening the distance from the frame 12 to the blower 19.

[0124] Additionally, the first cover member 15 is mounted to the intake section 14 via the first hinge shaft 43, allowing the first cover member 15 to face the opposite side of the rectifier 16 along arrow H (see reference). Figure 8 The rectifier 16 is rotated and separated from the air intake 41. Therefore, with the first cover member 15 separated from the air intake, the rectifier 16 can be moved to the location where the first cover member 15 was placed. That is, the rectifier 16 and the first cover member 15 can be swapped at the air intake 41, thereby shortening the distance from the frame 12 to the rectifier 16.

[0125] In this way, by shortening the distance from the frame 12 to the blower 19, and also shortening the distance from the frame 12 to the rectifier 16, the pressure loss generated at the intake port 41 and the exhaust port 55 can be reduced more appropriately when recovering carbon dioxide from the atmosphere.

[0126] Furthermore, by installing the blower 19 in the exhaust section 17 (exhaust port 55 side), a negative pressure can be created inside the frame 12 by the blower 19 when recovering carbon dioxide from the atmosphere. This negative pressure in the frame 12 ensures a good seal between the frame 12 and the blower 19. This reduces the load on the fourth hinge shaft 58 that mounts the blower 19, and also reduces the amount of air leaking from the gap between the frame 12 and the blower 19. In addition, it simplifies the fixing device for securing the blower 19 to the exhaust section 17.

[0127] Furthermore, the first hinge axis 43 is configured with its axis pointing vertically, and a first cover member 15 is mounted on the first hinge axis 43. This allows the first cover member 15 to rotate horizontally to the side about the first hinge axis 43. Additionally, the second hinge axis 44 is configured with its axis pointing vertically, and a rectifier 16 is mounted on the second hinge axis 44. This allows the rectifier 16 to rotate horizontally to the side about the second hinge axis 44.

[0128] Therefore, compared to, for example, rotating the first cover member 15 and the rectifier 16 in the up-down direction, the gravitational load when rotating the first cover member 15 and the rectifier 16 laterally horizontally about the first hinge axis 43 and the second hinge axis 44 respectively can be reduced. Thus, the first cover member 15 and the rectifier 16 can be rotated laterally horizontally with less force.

[0129] Furthermore, the third hinge axis 57 is positioned so that its axis is vertical, and the second cover member 18 is mounted on the third hinge axis 57. This allows the second cover member 18 to rotate horizontally to the side about the third hinge axis 57. Additionally, the fourth hinge axis 58 is positioned so that its axis is vertical, and a blower 19 is mounted on the fourth hinge axis 58. This allows the blower 19 to rotate horizontally to the side about the fourth hinge axis 58.

[0130] Therefore, compared to, for example, rotating the second cover member 18 and the blower 19 in the up-down direction, the gravitational load when rotating the second cover member 18 and the blower 19 laterally horizontally about the third hinge axis 57 and the fourth hinge axis 58 respectively can be reduced. Thus, the second cover member 18 and the blower 19 can be rotated laterally horizontally with less power.

[0131] Furthermore, the rotation of the first hinge shaft 43 is controlled by the first electric motor 81. Additionally, the rotation of the second hinge shaft 44 is controlled by the second electric motor 83. Therefore, when the first cover member 15, the rectifier 16, and the contact surface 14a of the intake section 14 are brought into contact, the torque (load) of the first electric motor 81 and the torque (load) of the second electric motor 83 can be appropriately managed. Thus, proper operation can be ensured when moving the first cover member 15 and the rectifier 16.

[0132] Furthermore, the rotation of the third hinge shaft 57 is controlled by the third electric motor 85. Additionally, the rotation of the fourth hinge shaft 58 is controlled by the fourth electric motor 87. Therefore, when the second cover member 18, the blower 19, and the contact surface 17a of the exhaust section 17 are brought into contact, the torque (load) of the third electric motor 85 and the torque (load) of the fourth electric motor 87 can be appropriately managed. Thus, proper operation can be ensured when moving the second cover member 18 and the blower 19.

[0133] It should be noted that the technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0134] For example, in the above embodiment, an example of providing the blower 19 on the exhaust port 55 side was described, but it is not limited to this. As other examples, the blower 19 may be provided on both the exhaust port 55 side and the intake port side, or the blower 19 may be provided only on the intake port side.

[0135] Furthermore, in the above embodiment, an example was described in which a first seal 42 is provided on the contact surface 14a of the intake section 14 and a second seal 56 is provided on the contact surface 17a of the exhaust section 17, but this is not a limitation. As another example, the first seal 42 and the second seal 56 may not be provided on the contact surfaces 14a and 17a.

[0136] Furthermore, without departing from the spirit of the present invention, the constituent elements in the above embodiments may be appropriately replaced with well-known constituent elements, and the above-described variations may also be appropriately combined.
