[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention as claimed, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be combined in any desired manner. Furthermore, the same reference numerals are used to designate identical or similar components, and redundant descriptions will be omitted.

[0010] First Embodiment <Device configuration> Fig. 1 is an external view of a gas treatment device 1 according to one embodiment of the present invention, and Fig. 2 is an explanatory diagram of the internal structure of the gas treatment device 1. The gas treatment device 1 is installed outdoors, recovers carbon dioxide from gas, and discharges gas with a high concentration of carbon dioxide, for example, in a building installed adjacent to an agricultural facility such as a vinyl greenhouse. In this embodiment, the gas to be treated is air.

[0011] The gas processing device 1 includes a hollow housing 10. The housing 10 forms the outer wall of the gas processing device 1 and houses the components of the gas processing device 1. The housing 10 of this embodiment has a top portion 11, a bottom portion 12, and a cylindrical outer peripheral portion 13 between the top portion 11 and the bottom portion 12. The top portion 11 and the bottom portion 12 are disk-shaped, with the area of ​​the bottom portion 12 being larger than the area of ​​the top portion 11. The outer peripheral portion 13 has a tapered shape that tapers from the bottom portion 12 to the top portion 11, and includes a vertical portion 13a that extends approximately vertically from the top portion 11 to the bottom portion 12, and an inclined portion 13b that inclines outward from the top portion 11 to the bottom portion 12.

[0012] The outer circumferential portion 13 is provided with an inlet portion 14 which is an intake port for untreated air and an outlet portion 15 which is an outlet port for treated air. In this embodiment, the inlet portion 14 is an opening formed in the outer circumferential portion 13, and the outlet portion 15 is formed by an exhaust pipe 41. In this embodiment, the inlet portion 14 is formed in the lower portion of the outer circumferential portion 13, and the outlet portion 15 is formed in the upper portion of the outer circumferential portion 13.

[0013] The internal space of the housing 10 is divided into a plurality of spaces S1 to S3 by partition walls 16 and 17. Space S1 communicates with an inlet portion 14, and an outlet portion 15 is formed in the outer peripheral portion 13 that forms space S3. Space S2 is a space located between space S1 and space S3, and an adsorbent / desorber 20 is disposed therein.

[0014] The adsorbent / desorber 20 includes a hollow container 21 that extends vertically. An air inlet 21a is provided at the bottom end of the container 21, and an exhaust port 21b is formed at the top end. The inlet 21a opens to space S1, and the exhaust port 21b opens to space S3. A carbon dioxide adsorbent / desorbent 22 is provided inside the container 21. The adsorbent / desorbent 22 is made of a material that adsorbs carbon dioxide at room temperature and releases the adsorbed carbon dioxide at high temperatures, such as an amine-based material, a polymer material, or an inorganic material. A member 34 is disposed in the storage space for the adsorbent 22. When the member 34 is heated or cooled, the adsorbent 22 is heated or cooled by thermal conduction.

[0015] The gas treatment device 1 includes a heating unit 30 capable of heating the adsorbing / desorbing material 22. The heating unit 30 includes a heat source 31 and a supply unit 32. In this embodiment, the heat source 31 is a solar heat collector. An opening 13c is formed in the inclined portion 13b of the outer circumferential portion 13, and the heat source 31 is provided so as to close the opening 13c. The heat source 31 is a shell-shaped solar heat collecting panel and forms part of the outer circumferential portion 13.

[0016] By providing the heating source 31, which is a solar heat collector, on the inclined portion 13b, sunlight is more easily irradiated, allowing the heat of sunlight to be absorbed efficiently. The supply unit 32 is disposed in the space S2, and is a unit that circulates a liquid heating medium between the heating source 31 and the adsorbent / desorber 20 via piping 33 and a member 34. The member 34 is, for example, a member that forms a flow path through which the liquid heating medium passes. The supply unit 32 is, for example, an electric pump. By operating the supply unit 32, the heat of sunlight obtained by the heating source 31 can be supplied to the member 34 via the liquid, and the adsorbent / desorbent 22 can be heated.

[0017] The gas processing device 1 includes a blower 2. The blower 2 includes a windmill installed outside the gas processing device 1, a blower 200 installed inside the gas processing device 1, and a transmission mechanism 300 that transmits the rotational force of the windmill 100 to the blower 200. The blower 200 is provided in the space S3. The blower 200 sucks in air from the space S3 and exhausts it to the outside of the housing 10 via the exhaust pipe 41. As the air from the space S3 is exhausted, the space S3 becomes negative pressure. Since the adsorbent / desorber 20, whose exhaust port 21b opens into the space S3, also becomes negative pressure, the adsorbent / desorber 20 sucks in air from outside the housing 10 via the inlet 14, the space S1, and the intake port 21a. In this way, an airflow that passes gas through the adsorbent / desorber 20 can be generated by operating the blower 200.

[0018] The wind turbine 100, which is the driving source of the blower 200, is a horizontal axis type wind turbine, and is supported so as to be freely rotatable on a vertical support shaft 50 erected on the ceiling 11. The wind turbine 100 has a main body 101, wind turbine blades 102, and a vertical tail 104; when the vertical tail 104 receives wind pressure, it rotates around the support shaft 50, and the wind turbine blades 102 are oriented upwind. By placing the wind turbine 100 in a high position, it is possible to more easily obtain wind power. Details of the wind turbine 100 and the transmission mechanism 300 will be described later.

[0019] Carbon dioxide concentration sensors 61 and 62 are disposed in spaces S1 and S3. From the detection results of the concentration sensors 61 and 62, the difference between the carbon dioxide concentration of the air in space S1 and the carbon dioxide concentration of the air in space S3 can be identified. In the adsorption process, if this difference is large, the adsorption effect of the adsorbent / desorbent 22 on carbon dioxide is high (the degree of adsorption is low), and if this difference is small, the adsorption effect of the adsorbent / desorbent 22 is low (the degree of adsorption is high). Therefore, by transitioning to the desorption process when this difference is small, carbon dioxide can be efficiently captured.

[0020] The control circuit 60 is an electronic circuit that controls the operation of the gas treatment device 1. The control circuit 60 includes, for example, a processor represented by a CPU, a storage device, an input / output interface that relays between the processor and external devices, a communication interface that communicates with a higher-level controller (for example, a user's mobile terminal or personal computer), a drive circuit that drives the actuators, and a signal processing circuit that processes detection signals from the sensors. The storage device is a semiconductor memory such as a ROM or RAM, or a hard disk. The processor executes a control program stored in the storage device to control the operation of the gas treatment device 1 (particularly the operation of the supply unit 32).

[0021] <Operation example> 3(A) and 3(B) are diagrams illustrating the operation of the gas treatment device 1. Fig. 3(A) shows an adsorption step in which carbon dioxide is adsorbed onto the adsorbent 22, and Fig. 3(B) shows a desorption step in which the carbon dioxide adsorbed onto the adsorbent 22 is released from the adsorbent 22.

[0022] In either process, the fan 200 is driven by the rotation of the windmill 100 caused by wind power. When the fan 200 is driven, outside air is sucked in from the inlet 14, passes through the space S1, the adsorber / desorber 20, the space S3, the fan 200, and the exhaust pipe 41, and is exhausted from the outlet 15.

[0023] During the adsorption process, the supply unit 32 is stopped and the liquid heating medium is not circulated. The temperature of the adsorbent / desorber 20 is approximately the same as the outside air temperature, and as the air passes through the adsorbent / desorbent material 22, the carbon dioxide contained in the air is adsorbed by the adsorbent / desorbent material 22. Air with a reduced carbon dioxide concentration is exhausted from the outlet 15. The adsorption process is carried out, for example, at night.

[0024] When the difference in carbon dioxide concentration between the spaces S1 and S3 based on the detection results of the carbon dioxide concentration sensors 61, 62 (FIG. 2) falls below a threshold, it is determined that the adsorption of carbon dioxide by the adsorbent / desorbent 22 is saturated, and the process proceeds to the desorption step.

[0025] The desorption process is basically carried out during the day when solar heat can be utilized by the heating source 31, which is a solar heat collector. The supply unit 32 is driven to circulate the liquid heating medium. By supplying the liquid heating medium, the adsorbent / desorbent material 22 is heated, and carbon dioxide is released from the adsorbent / desorbent material 22. Air with an increased carbon dioxide concentration is exhausted from the outlet 15. The exhausted air can be used in agricultural equipment, etc. The exhausted air may be stored in a tank.

[0026] In this manner, the gas treatment device 1 of this embodiment can recover carbon dioxide contained in the air by repeating the adsorption step and the desorption step.

[0027] In the gas treatment device 1 of this embodiment, the interior of the housing 10 is divided into multiple spaces S1 to S3 by partition walls 16 and 17, and the spaces S1 and S3 are used as gas intake and exhaust paths for the adsorbent / desorber 20. The piping to the adsorbent / desorber 20 is reduced, preventing the device configuration from becoming complicated and making it more compact. By performing carbon dioxide adsorption and desorption in the common adsorbent / desorber 20, it is possible to make the device more compact than a configuration provided with an adsorption tower and a desorption tower (capture tower).

[0028] By using a solar heat collector as the heat source 31, it is possible to utilize natural energy and save power, and by using the solar heat collector as part of the outer periphery 13 of the housing 10, it is possible to make the device more compact. In addition, by placing the solar heat collector, which is the heat source 31, on the inclined portion 13b, it is possible to make the area that receives sunlight larger.

[0029] By using the windmill 100 as the driving source of the blower 200, natural energy can be utilized to save power. By arranging the blower 200 and the outlet 15 in the upper part of the housing 10, the heated air containing carbon dioxide released from the adsorbent / desorbent material 22 by heating in the heating unit 30 can be efficiently exhausted to the outside by utilizing the rising air current.

[0030] <Structure of the wind turbine and transmission mechanism> The configuration of the wind turbine 100 and transmission mechanism 300 will now be described. Figure 4 is an explanatory diagram of the internal structure of the wind turbine 100 and the upper part of the transmission mechanism 300. Inside the hollow main body 101, a rotating shaft 103 extending horizontally from the wind turbine blades 102 is rotatably supported by bearings BR and is movable in the axial direction of the rotating shaft 103. Arrows X1 and X2 indicate the axial direction of the rotating shaft 103, with arrow X1 indicating the direction from the vertical tail 104 side towards the wind turbine blades 102 and arrow X2 indicating the opposite direction to arrow X1. When the axial direction of the rotating shaft 103 is not distinguished between the X1 direction and the X2 direction, it is simply referred to as the X direction.

[0031] Disk-shaped flange portions 103a and 103b are arranged on the rotating shaft 103 and spaced apart in the X direction. A braking member 400 is arranged facing the flange portion 103a in the X direction. The braking member 400 is fixed to the main body 101 and is a disk-shaped member having a central hole through which the rotating shaft 103 is inserted, and a material with a high friction coefficient is used on the surface facing the flange portion 103a. The braking member 400 brakes the rotation of the rotating shaft 103 when the flange portion 103a comes into contact with it.

[0032] A plurality of dampers 410 are arranged on the flange portion 103b facing each other in the X direction. Each damper 410 includes a cylinder 411 and a piston 412 inserted into the cylinder 411. A biasing member 413 that biases the piston 412 in the X1 direction is built into the cylinder 411. In this embodiment, the biasing member 413 is a coil spring.

[0033] A pressing portion 412a is provided at the end of piston 412 on the X1 direction side, and a rotatable roller 412b is attached to pressing portion 412a so as to face flange portion 103b. Pressing portion 412a constantly urges rotating shaft 103 in the X1 direction due to the biasing force of biasing member 413. The presence of roller 412b minimizes friction with flange portion 103b, thereby reducing the rotational resistance of rotating shaft 103.

[0034] An air vent hole 414 that functions as a flow valve is formed at the bottom of the cylinder 411. As the piston 412 moves relative to the cylinder 411, air in the cylinder 411 is expelled through the air vent hole 414, and conversely, external air is drawn into the cylinder 411 through the air vent hole 414. The moving speed of the piston 412 can be adjusted by changing the size of the air vent hole 414.

[0035] The transmission mechanism 300 includes a drive transmission shaft 310 whose axial direction is different from that of the rotation shaft 103, and a gear device 320. The support shaft 50 is a cylindrical shaft, and the drive transmission shaft 310 passes through the inside of the support shaft 50. The drive transmission shaft 310 extends in the vertical direction, and the axial direction of the drive transmission shaft 310 and the axial direction of the rotation shaft 103 are perpendicular to each other.

[0036] Gear device 320 is a direction-changing gear that changes the direction of drive transmission. In this embodiment, gear device 320 is a bevel gear device, and includes bevel gear 321 fixed to rotation shaft 103 and bevel gear 322 fixed to the end of drive transmission shaft 310. The rotational force of wind turbine 100 is transmitted to transmission mechanism 300 by gear device 320.

[0037] The operation of the wind turbine 100 depending on the wind speed will be described with reference to Figures 4 and 5. When a strong wind (for example, a wind speed of 20 m / s) blows, the wind turbine 100 rotates at a high speed, which may damage the wind turbine 100 itself or the transmission mechanism 300. In the case of this embodiment, when the wind speed reaches a predetermined speed, the rotating shaft 103 is braked and the transmission of driving force between the wind turbine 100 and the drive transmission mechanism 300 is cut off.

[0038] Figure 4 shows a state where the wind speed is low. Wind pressure acts on the wind turbine blades 102 in the X2 direction. However, the biasing force of the biasing member 413 of the damper 410 presses the rotating shaft 103 in the X1 direction via the flange portion 103b. The biasing force of the biasing member 413 overcomes the wind pressure, and the wind turbine blades 102 and the rotating shaft 103 are maintained in their normal positions. The rotation of the wind turbine blades 102 and the rotating shaft 103 is transmitted to the drive transmission shaft 310 via the gear device 320, and the braking member 400 is separated from the flange portion 103a, so no braking force is applied.

[0039] 5 shows a state where the wind speed is high. The pressure on the wind turbine blade 102 in the X2 direction increases due to the wind pressure, and the wind pressure overcomes the biasing force of the biasing member 413 of the damper 410, pushing the piston 412 into the cylinder 411 while displacing the wind turbine blade 102 and the rotating shaft 103 in the X2 direction. The bevel gear 321 of the rotating shaft 103 moves away from the bevel gear 322 of the drive transmission shaft 310, and the meshing between them is released. Therefore, the rotation of the wind turbine blade 102 and the rotating shaft 103 is no longer transmitted to the drive transmission shaft 310 via the gear device 320. In addition, the flange portion 103a abuts against the braking member 400, and a braking force is applied. This reduces the rotation speed of the wind turbine blade 102 and the rotating shaft 103.

[0040] When the wind speed decreases again, the state returns from that shown in Figure 5 to that shown in Figure 4, and the rotation of the wind turbine blades 102 and the rotating shaft 103 is again transmitted to the drive transmission shaft 310 via the gear device 320, and the braking member 400 moves away from the flange portion 103a, so no braking force is applied. As described above, in this embodiment, the wind turbine blades 102 and the rotating shaft 103 are displaced in the X2 direction and also in the X1 direction in response to changes in wind force. At this time, the displacement speed of the wind turbine blades 102 and the rotating shaft 103 is slowed down by the damper 410. Specifically, the moving speed of the piston 412 is regulated by the air vent hole 414, which prevents the wind turbine blades 102 and the rotating shaft 103 from suddenly displacing. When the bevel gear 321 and the bevel gear 322 return from a separated state (FIG. 5) to a meshed state (FIG. 4), or when the flange portion 103a abuts against the braking member 400 (FIG. 5), the impact between the members is alleviated, preventing damage.

[0041] 6 is an explanatory diagram of the middle and lower parts of the transmission mechanism 300. When the rotation speed of the wind turbine 100 is low, the blower 200 cannot generate sufficient wind power, while the wear of the rotating parts progresses. In this embodiment, a mechanism is provided that does not transmit the rotation of the wind turbine 100 to the blower 200 when the wind speed is low.

[0042] The drive transmission shaft 310 extends vertically, passing through the outer wall (ceiling part 11) of the gas processing device 1, and includes an upper shaft part 311 and a lower shaft part 312. A blocking part 370 is provided between the shaft part 311 and the shaft part 312.

[0043] In this embodiment, the interrupter 370 is a centrifugal clutch and includes a main body 371 fixed to the lower end of the shaft 311, a plurality of movable parts 372 that are displaceable in the radial direction of the drive transmission shaft 310 relative to the main body 371, and a cylindrical outer case 373 fixed to the shaft 312 and surrounding the main body 371 and the movable parts 372. Arrow R1 indicates the inward direction in the radial direction of the drive transmission shaft 310, and arrow R2 indicates the outward direction in the radial direction of the drive transmission shaft 310.

[0044] Movable part 372 is constantly urged in the R1 direction relative to main body part 371 by an elastic member (not shown), such as a spring. When wind turbine 100 is exposed to wind with a wind speed of 2 m / s or more, centrifugal force acts on movable part 372 due to the rotation of shaft part 311, friction between movable part 372 and the inner circumferential surface of outer case 373 is high, and the rotational force of wind turbine 100 is transmitted between shaft part 311 and shaft part 312. On the other hand, when wind turbine 100 is exposed to a light wind with a wind speed of 2 m / s or less, shaft part 311 rotates at an extremely slow speed, friction between movable part 372, which is urged in the R1 direction, and the inner circumferential surface of outer case 373 is low, and transmission of the rotational force of wind turbine 100 between shaft part 311 and shaft part 312 is blocked.

[0045] In this way, when the wind speed is low, the rotation of wind turbine 100 can be prevented from being transmitted to blower 200. Blocking section 370 may be installed at a location other than drive transmission shaft 310, but because drive transmission shaft 310 is configured to be located upstream in the drive transmission direction in transmission mechanism 300, blocking drive transmission here can prevent wear from progressing in more downstream component parts.

[0046] Next, the transmission mechanism 300 includes a drive transmission shaft 330 having an axial direction different from that of the drive transmission shaft 310, and a gear device 340. The drive transmission shaft 330 extends horizontally, and the axial direction of the drive transmission shaft 330 and the axial direction of the drive transmission shaft 310 are perpendicular to each other.

[0047] Gear device 340 is a direction-changing gear that changes the direction of drive transmission. In this embodiment, gear device 340 is a bevel gear device, and includes bevel gear 341 fixed to the lower end of drive transmission shaft 310 and bevel gear 342 fixed to the end of drive transmission shaft 330. The rotational force of wind turbine 100 is transmitted to speed-increasing section 350 by gear device 340.

[0048] The speed increasing unit 350 includes a spur gear 351 fixed to the drive transmission shaft 330 and a spur gear 352 fixed to the output shaft 360. By using the spur gear 352, which has fewer teeth than the spur gear 351, the rotation speed of the drive transmission shaft 330 is increased and transmitted to the output shaft 360. The rotation speed of the wind turbine 100 can be increased by the speed increasing unit 350 and transmitted to the blower 200.

[0049] Pulley 361 is fixed to output shaft 360. Blower 200 includes rotating shaft 202 to which blades 201 are fixed, and pulley 203 is fixed to rotating shaft 202. An endless belt 362 is wound between pulley 361 and pulley 203, and the rotational force of wind turbine 100 is transmitted from output shaft 360 to rotating shaft 202, thereby driving blower 200.

[0050] As described above, in this embodiment, the rotational force of the wind turbine 100 is transmitted to positions separated in the vertical direction by the drive transmission shaft 310, and further transmitted to positions separated in the horizontal direction by the drive transmission shaft 330. By designing the axial lengths of the drive transmission shaft 310 and the drive transmission shaft 330, the transmission position of the rotational force of the wind turbine 100, i.e., the position of the blower 200, can be adjusted, providing a technology that allows a high degree of freedom in the placement of the blower 200 that uses the wind turbine 100 as a drive source.

[0051] Second Embodiment In preparation for weather changes, a device for storing heat generated by the heating source 31, which is a solar heat collector, may be provided. FIG. 7 shows one example. In the example of FIG. 7, a tank 36 is provided in the circulation path of the liquid by the supply unit 32. The tank 36 is connected to the piping 33 and stores a certain amount of liquid. By providing the tank 36, the amount of circulating liquid can be increased, and solar heat can essentially be stored in the tank 36. When sunlight decreases due to changes in weather or after sunset, heating of the adsorbent / desorbent material 22 can be continued, and the desorption process time can be extended.

[0052] Third Embodiment When adsorbing carbon dioxide, the adsorption efficiency of the adsorbent / desorber 22 may decrease due to moisture in the gas. Therefore, the adsorbent / desorber 20 may be provided with a moisture adsorbent / desorber. FIG. 8 shows one example. In the illustrated example, the adsorbent / desorber 20 accommodates a moisture adsorbent / desorber 23 in addition to the carbon dioxide adsorbent / desorber 22. The adsorbent / desorber 23 is arranged upstream of the adsorbent / desorber 22 in the gas flow direction. The adsorbent / desorber 23 is arranged between the adsorbent / desorber 22 and the inlet 21a. The adsorbent / desorber 23 is, for example, silica gel, zeolite, metal organic frameworks (MOFs), covalent organic frameworks (COFs), or activated carbon.

[0053] In this embodiment, a condenser 70 is disposed in the space S3 to reduce the moisture content of the gas exhausted from the blower 200. The condenser 70 is provided midway along the exhaust pipe 15, condenses the moisture in the gas being exhausted, and drains the condensed moisture through a drain pipe 71. A known condenser can be used as the condenser 70, such as an air-cooled or water-cooled cooler for cooling the gas.

[0054] In this embodiment, by providing the adsorbent / desorbent 23, moisture in the gas is adsorbed by the adsorbent / desorbent 23 in the adsorption step. A drier gas is supplied to the adsorbent / desorbent 22, improving the carbon dioxide adsorption performance. In the desorption step, the moisture adsorbed by the adsorbent / desorbent 23 by heating is desorbed (vaporized) from the adsorbent / desorbent 23 and is exhausted together with the carbon dioxide desorbed from the adsorbent / desorbent 22. However, since the moisture in the gas exhausted by the blower 200 is removed by the condenser 70, it is possible to exhaust dry gas with a high carbon dioxide content from the outlet 15.

[0055] <Fourth embodiment> A configuration may be adopted in which a gas with a low carbon dioxide content (lean gas) that is discharged to the outside of the device in the adsorption process and a gas rich in carbon dioxide (rich gas) that is discharged to the outside of the device in the desorption process are distinguished and discharged to the outside of the device. Figure 9 shows an example of such a configuration.

[0056] In the illustrated example, a switch 42 is connected to an exhaust pipe 41, and exhaust pipes 43 and 44 are connected to the switch 42. The switch 42 switches which of the exhaust pipes 43 and 44 is connected to the exhaust pipe 41. For example, in the adsorption process, the switch 42 connects the exhaust pipe 41 to the exhaust pipe 43, and lean gas is exhausted from the exhaust pipe 43. On the other hand, in the desorption process, the switch 42 connects the exhaust pipe 41 to the exhaust pipe 44, and rich gas is exhausted from the exhaust pipe 44.

[0057] By switching the exhaust pipe for exhausting lean gas and rich gas, the effort of removing lean gas can be eliminated in agricultural equipment and storage tanks that receive a supply of rich gas from the gas treatment device 1.

[0058] Fifth Embodiment Instead of the solar heat collector used as the heat source 31, a solar power generator (solar panel) may be used as the power source. FIG. 10 shows an example. In the example of FIG. 10, a solar power generator 31' is provided instead of the heat source 31, which is a solar heat collector. The solar power generator 31' constitutes part of the outer periphery 13, similar to the solar heat collector of the first embodiment. A power supply device 81 and a capacitor 82 are provided in the space S2. The power supply device 81 stores the power generated by the solar power generator 31' in the capacitor 82, and supplies power from the capacitor 82 to each component of the gas treatment device 1.

[0059] The heating unit 30′ of this embodiment is disposed in the space S2 and includes a heat source (electric heater) 35 that is driven by power from a capacitor 82. The supply unit 32 circulates a liquid, which is a heating medium, between the heat source 35 and the adsorbent / desorber 20 via a pipe 33′ and a member 34. The power stored in the capacitor 82 can also be used to drive the heat source 35 and the supply unit 32.
