Description

Technical Field

[0001] The present invention relates to an air flow generator, a filter system, a power generation system, and a carbon dioxide removal system.

Background Art

[0002] In vehicles that move passengers, such as airplanes and passenger cars, it is necessary to generate an air flow inside the vehicle from various viewpoints, particularly for the purpose of improving the cleanliness inside the vehicle. In order to generate an air flow inside the vehicle, it is necessary to create a pressure difference inside the vehicle. Specifically, either one or both of generating a high-pressure part and generating a low-pressure part for degassing are performed to generate an air flow from the high-pressure part to the low-pressure part. For example, the high-pressure part is generated by a compressor, and the low-pressure part is generated by a degassing pump such as a vacuum pump.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, for devices that generate high-pressure and low-pressure parts, such as compressors and degassing pumps, a large amount of power is generally required. Therefore, in vehicles such as airplanes and passenger cars, which are moving bodies with restrictions on power consumption, there is a problem of high required power. In addition, devices such as compressors and degassing pumps have mechanical moving parts that perform rotational or reciprocating motions, and there are problems such as the device becoming large or the device being prone to failure.

[0004] In vehicles traveling at high speeds, a relatively large air flow is generated outside the vehicle relative to the vehicle during travel. However, since the air flow generated outside the vehicle does not require power, it is advantageous for vehicles such as airplanes and passenger cars, but it cannot be directly controlled and utilized to generate an air flow inside the vehicle.

[0005] If a pressure difference can be generated by utilizing the airflow outside a vehicle moving at high speed, it would be preferable as a small, reliable device that does not require a large amount of power and has no mechanically moving parts. In particular, it is desirable to generate airflow inside the vehicle and thereby generate a low-pressure source. Here, a "low-pressure source" is defined as an environment controlled to have a pressure lower than the pressure of the surrounding atmosphere. Specifically, this is defined as a state where the pressure at the point where airflow is drawn in to generate airflow inside the moving vehicle is lower than the pressure around that chamber. The airflow generating device of the present invention functions as a low-pressure source generating device, and its significance lies in the fact that it produces the effect of generating a low-pressure source.

Embodiments for Carrying Out the Invention

[0015] [Embodiment 1] Next, referring to FIGS. 1A to 2B, an air flow generator 1, which is a low-pressure source generator of the present invention according to Embodiment 1 of the present invention, will be described. FIG. 1A is a perspective view of a conceptual diagram of a basic form of the air flow generator 1 according to Embodiment 1 of the present invention. FIG. 1B is a cross-sectional view of the air flow generator according to Embodiment 1 of the present invention, focusing on the moving body and the main pipeline. FIG. 1C is a perspective view of a conceptual diagram of a modified form of the basic form of the air flow generator 1 of the present invention. FIG. 1D is a system diagram of the air flow generator according to Embodiment 1 of the present invention. FIG. 1E is a diagram showing a usage example of the air flow generator according to Embodiment 1 of the present invention. FIG. 2A shows an aircraft to which the air flow generator 1 of the present invention is applied. FIG. 2B shows a railway vehicle to which the air flow generator 1 of the present invention is applied.

[0016] The air flow generator 1 of the present invention is applied to a moving vehicle (hereinafter, "moving body"). The moving body is a vehicle that moves particularly at high speed, for example, an aircraft such as a passenger aircraft, a railway vehicle such as a bullet train or a conventional line train, or an automobile. The air flow generator 1 is disposed inside the moving body. That is, the vehicle to which the air flow generator 1 is applied is disposed inside the structural wall surface 10 of the moving body. An air intake 10a and an air outlet 10b are disposed on the structural wall surface 10.

[0017] The air intake 10a is an opening for taking in the air (first atmosphere) outside the moving body into the inside of the air flow generator 1, and the air outlet 10b is an opening for discharging the first atmosphere taken in from the air intake 10a and passing through the air flow generator 1 to the outside of the moving body. For example, in the case of the aircraft 81 in FIG. 2, the air intake 10a is disposed in the front lower part of the side surface of the aircraft 81, and the air outlet 10b is disposed in the rear lower part of the side surface of the aircraft 81.

[0018] Furthermore, for example, in the case of the railway vehicle 82 shown in Figure 3, an air intake 10a is located at the lower front of the side of each vehicle of the railway vehicle 82, and an air outlet 10b is located at the lower rear of each vehicle. In either case, the front of the moving body is the upstream side where the air intake 10a is located, and the rear of the moving body is the downstream side where the air outlet 10b is located. Here, an aircraft 81 and a railway vehicle 82 are shown as examples, but the airflow generator 1 can be applied to all moving bodies and is not limited to just the aircraft 81 and the railway vehicle 82.

[0019] The airflow generator 1 of the present invention comprises a main conduit 11, an induction hole 11c, and an air conduit 13. The main conduit 11 has a first opening 11a and a second opening 11b at both ends. The induction hole 11c is located on the wall surface of the main conduit 11.

[0020] The first opening 11a communicates with the air intake 10a, and the second opening 11b communicates with the air outlet 10b. The air intake 10a and the air outlet 10b are exposed to the first atmosphere. As a result, a primary flow P of the first atmosphere is generated in the main pipeline 11, from the first atmosphere taken in from the air intake 10a to the first opening 11a and then to the second opening 11b.

[0021] The main pipeline 11 is a pipeline that extends along the direction of travel of the moving body. Since the air intake 10a is positioned to open forward in the direction of travel of the moving body, the first opening 11a is also positioned forward in the direction of travel of the moving body so as to avoid resistance to the flow of the first atmosphere from the air intake 10a. Similarly, since the air outlet 10b is positioned to open backward in the direction of travel of the moving body, the second opening 11b is also positioned backward in the direction of travel of the moving body so as to avoid obstruction to the flow of the first atmosphere from the air outlet 10b. The primary flow P of the first atmosphere is the flow of air relative to the moving body.

[0022] For example, the main conduit 11 can be a flow path defined between a portion of the outer or inner side of the structural wall surface 10 of the moving body and a plate member positioned opposite that portion, as shown in Figure 1B. Alternatively, the main conduit 11 can be a hollow, tubular conduit extending along the direction of travel of the moving body. The main conduit 11 can be formed in various ways, as long as it extends along the direction of travel of the moving body. For example, as shown in Figure 1B, the main conduit 11 can be formed inside the moving body as a separate pipe from the structural wall surface 10. Although not shown, a plate can also be placed inside the moving body opposite the structural wall surface 10, and the structural wall surface 10 can be used as part of the main conduit 11 by forming the main conduit 11 between this plate and the structural wall surface 10.

[0023] An induction hole 11c is drilled in the wall of the main pipeline 11. The induction hole 11c can be, for example, a slit-shaped elongated hole that extends perpendicular to the direction in which the main pipeline 11 extends. The size of the cross-section of the main pipeline 11 can be kept constant from the first opening 11a to the second opening 11b, but as shown in Figures 1A and 1B, the cross-section of the main pipeline 11 may be large at the first opening 11a and the second opening 11b, and then narrow near the induction hole 11c.

[0024] If the cross-sectional size of the main pipeline 11 is kept constant from the first opening 11a to the second opening 11b, the velocity of the primary flow P inside the main pipeline 11 will be approximately constant. However, if the cross-sectional size of the main pipeline 11 is narrowed near the induction hole 11c, the velocity of the primary flow P will accelerate near the induction hole 11c. Furthermore, the shape of the wall surface of the main pipeline 11 may be made variable, and a control device for controlling the wall surface of the main pipeline 11 may be installed to control the static pressure near the induction hole 11c by varying the ratio of the cross-sectional area of ​​the induction hole 11c to the area of ​​the first opening 11a.

[0025] The air conduit 13 is located inside the mobile body, in an environment with a second atmosphere that is different from the first atmosphere. Here, "different" means that although both the first and second atmospheres are air, the first atmosphere is the air outside the mobile body, while the second atmosphere is the atmosphere inside the mobile body. For example, as will be explained below, the second atmosphere is the air in the environment inside the mobile body, and can be said to be air containing carbon dioxide and bacteria emitted by personnel inside the mobile body. The air conduit 13 has a flow channel inlet 13a and a flow channel outlet 13b. In one embodiment of Embodiment 1, as shown in Figure 1A, the flow channel inlet 13a can be exposed to the inside of the mobile body. In this case, the flow channel inlet 13a functions as a low-pressure source, and the secondary flow Q of the second atmosphere inside the mobile body is taken in directly from the flow channel inlet 13a into the air conduit 13. Taken in from the flow channel inlet 13a into the air conduit 13, it flows out to the intake hole 11c via the flow channel outlet 13b of the air conduit 13.

[0026] The basic configuration of Embodiment 1 is one in which the flow path inlet 13a of the air conduit 13 is exposed. However, as a modified configuration of the basic configuration of Embodiment 1, as shown in Figure 1C, a low-pressure chamber 15 is provided with an opening 15a which serves as a second atmosphere acquisition port and is exposed to the second atmosphere inside the mobile body, and the flow path inlet 13a communicates with the inside of the mobile body via the inside of the low-pressure chamber 15. In this case, the low-pressure chamber 15 functions as a low-pressure source inside the mobile body, and the secondary flow Q of the second atmosphere inside the mobile body is taken in from the opening 15a of the low-pressure chamber 15 and into the air conduit 13 via the low-pressure chamber 15. It is taken in from the opening 15a through the low-pressure chamber 15 into the air conduit 13 and flows out to the induction hole 11c via the flow path outlet 13b of the air conduit 13. The following explanation will be based on a configuration in which a low-pressure chamber 15 is provided (Figure 1C), but the same principle applies to cases where the flow channel inlet 13a is exposed to the interior of the moving body and functions as a low-pressure source, without the provision of a low-pressure chamber 15.

[0027] Because the flow velocity of the second atmosphere in the air conduit 13 is lower than that of the primary flow P of the first atmosphere in the main conduit 11, the static pressure of the first atmosphere near the induction hole 11c in the main conduit 11 is lower than that of the second atmosphere in the air conduit 13. Therefore, at the flow outlet 13b of the air conduit 13, the second atmosphere is drawn into the main conduit 11 from the induction hole 11c. As a result, the pressure of the second atmosphere near the flow outlet 13b of the air conduit 13 is lower than that of the flow inlet 13a, and to compensate for this, a secondary flow Q of the second atmosphere can be generated through the air conduit 13 from the flow inlet 13a to the flow outlet 13b. As a result, a secondary flow Q of the second atmosphere is generated from inside the low-pressure chamber 15 through the flow inlet 13a, and the internal pressure of the low-pressure chamber 15 decreases. Since the low-pressure chamber 15 has an opening 15a, a secondary flow Q of the second atmosphere surrounding the low-pressure chamber 15 is generated, which has the effect of creating flow to the low-pressure chamber 15, which is the low-pressure source in the environment in which the low-pressure chamber 15 is installed. For example, even if there are no openings such as windows inside the room of a mobile body, a secondary flow Q is generated inside the room of the mobile body 80.

[0028] Figure 1E is a diagram showing a cross-section of the pressurized section inside an aircraft 81, which is a passenger aircraft. As shown in Figure 1E, by arranging the low-pressure chamber 15, the air inside the aircraft 81, which is the second atmosphere, flows toward the low-pressure chamber 15. For example, by providing multiple low-pressure chambers 15 (1501, 1502, 1503, 1504, 1505, 1506) and fluidically connecting each of the low-pressure chambers 1501, 1502, 1503, 1504, 1505, 1506 to the flow path inlet 13a, a secondary flow Q can be induced toward each of the openings 15a (1501a, 1502a, 1503a, 1504a, 1505a, 1506a). Naturally, it is also possible to have a configuration in which the flow path inlet 13a is exposed without arranging the low-pressure chambers 15 (1501, 1502, 1503, 1504, 1505, 1506).

[0029] For example, by generating an airflow directed towards the low-pressure chamber 15, various purposes can be achieved, such as removing bacteria and other contaminants from the air inside the mobile unit 80, or reducing the increase in carbon dioxide exhaled by passengers. The internal space of the low-pressure chamber 15 can be used for a variety of purposes.

[0030] Furthermore, as mentioned above, if the cross-sectional size of the main pipe 11 near the induction hole 11c is narrowed to be smaller than that of the first opening 11a and the second opening 11b, the pressure of the first atmosphere near the induction hole 11c of the main pipe 11 becomes particularly low due to the Venturi effect. This makes it possible to further increase the secondary flow Q of the second atmosphere through the air conduit 13 from the flow inlet 13a to the flow outlet 13b.

[0031] When the airflow generator 1 is applied to a mobile body, the air conduit 13, the flow path inlet 13a, and the flow path outlet 13b are located inside the mobile body. The second atmosphere is the atmosphere inside the mobile body's cabin. If the flow path inlet 13a is connected to, for example, the passenger compartment inside the mobile body, the secondary flow Q of the atmosphere inside the passenger compartment can be naturally merged with the primary flow P through the induction hole 11c and discharged to the outside of the mobile body. Specifically, for example, in the case of an aircraft 81, the speed of the primary flow P is 900 km / h, and at this time the speed of the secondary flow Q is 100 km / h.

[0032] Valves 14a, 14b, and 14c can be placed at the first opening 11a, the second opening 11b, and the induction hole 11c, respectively, as needed. This allows for limiting the timing of discharge to the outside, and by controlling the opening and closing amounts of valves 14a, 14b, and 14c, the flow rate of the secondary flow Q of the second atmosphere via the air conduit 13 from the flow inlet 13a to the flow outlet 13b can be controlled. Furthermore, valves (not shown) can also be placed at the flow inlet 13a and the flow outlet 13b, as needed.

[0033] Furthermore, by placing valves (opening / closing doors) at the air intake 10a and air outlet 10b, which are openings, and controlling the area of ​​the openings of the doors, the flow of the first atmosphere itself can be controlled, and the secondary flow Q of the second atmosphere can be controlled via the control of the primary flow P of the first atmosphere. For example, a control device (not shown) can be placed to control the opening and closing amounts of the air intake 10a, air outlet 10b, and valves 14a, 14b, and 14c, thereby controlling the flow velocity of the first atmosphere and the flow velocity of the second atmosphere inside the main pipeline 11. Similarly, if valves (not shown) are placed at the flow path inlet 13a and flow path outlet 13b, the flow rate and flow velocity of the second atmosphere may be directly controlled by having the control device control the opening and closing amounts of these valves.

[0034] The airflow generator 1 can directly generate airflow inside a moving body without requiring mechanical moving parts or electricity. Furthermore, the airflow generated by the airflow generator 1 can create a low-pressure source at the flow path inlet 13a, so the airflow generator 1 also functions as a low-pressure source generator. By utilizing the airflow generated by the airflow generator 1 of Embodiment 1 and the low-pressure source generated therefrom, the airflow generator 1 can be applied to devices that achieve various purposes.

[0035] For example, in the basic configuration of Embodiment 1, the airflow generator 1 can function as a filter system by placing a filter member (not shown) in the flow path cross-section of the air conduit 13. For example, the filter member (not shown) can be placed in the flow path inlet 13a or inside the air conduit 13. As a result, all of the secondary flow Q of the second atmosphere introduced into the air conduit 13 passes through the filter member (not shown), and by selecting an appropriate filter member according to the target to be captured, it can also function as a filter system. Furthermore, when the airflow generator 1 is to function as a filter system 2, a configuration can be adopted in which the filter member is placed inside the low-pressure chamber 15, in a modified configuration of the basic configuration of Embodiment 1 in which the low-pressure chamber 15 is placed. This will be described as Embodiment 2 below. The selection of the filter member will be described later in Embodiment 2.

[0036] Furthermore, for example, in the basic form of Embodiment 1, a rotor blade can be placed near the flow channel inlet 13a, and the rotation axis of the rotor blade can be coupled to a generator to create a power generation system. That is, the rotor blade (not shown) is rotated by the secondary flow Q of the second atmosphere introduced into the air conduit 13 from the flow channel inlet 13a, and the rotation of the rotation axis by the rotor blade (not shown) rotates the power generation element inside the generator in a magnetic field, thereby generating electricity (not shown). Moreover, when the airflow generator 1 functions as a power generation system 3, in a form in which a low-pressure chamber 15 is arranged, which is a modified form of the basic form of Embodiment 1, the rotor blade can be placed inside the low-pressure chamber 15. This will be described later as Embodiment 3.

[0037] [Embodiment 2] Next, with reference to Figures 3A and 3B, a filter system 2 using the airflow generator 1 as Embodiment 2 of the present invention will be described. Figure 3A is a perspective view of the filter system 2 to which the airflow generator 1 of Embodiment 1 of the present invention is applied. Figure 3B shows a system diagram of the filter system 2. The difference from Embodiment 1 is that the filter 15b is placed in the low-pressure chamber 15. Here, only the differences from Embodiment 1 will be described. As described above, in Embodiment 1, the filter system 2 may be made by omitting the low-pressure chamber 15 and placing the filter 15b in the flow path inlet 13a of the air conduit 13.

[0038] The filter system 2 is a device intended for air purification, such as removing bacteria and other contaminants from the air inside a mobile vehicle, or for removing carbon dioxide exhaled by passengers. Its purpose is to purify the contaminated air inside the mobile vehicle and then release it into the outside air to protect the environment.

[0039] A filter 15b is placed inside the low-pressure chamber 15. The filter 15b has the characteristic of allowing the second atmosphere to pass through but not allowing the components of the target to be captured, which are impurities contained in the second atmosphere, to pass through. As a result, the secondary flow Q containing the target to be captured is introduced into the low-pressure chamber 15 from the opening 15a and passes through the inside of the filter 15b. The target to be captured is captured by the filter 15b, and the secondary flow Q from which the target to be captured flows from the low-pressure chamber 15 through the flow path inlet 13a to the air conduit 13. The second atmosphere is, as described above, the air inside the room of the mobile body, such as the air in the passenger compartment. The air in the second atmosphere contains carbon dioxide and bacteria exhaled by the people inside the room of the mobile body, such as passengers in the passenger compartment.

[0040] As the filter 15b, a porous material can be selected according to the target to be captured. For air purification, for example, porous materials with many minute pores such as HEPA filters, activated carbon, and nonwoven fabrics can be widely used. Furthermore, in the case of carbon dioxide removal, the filter 15b can be a carbon dioxide adsorbing porous material with many minute pores formed from materials that adsorb carbon dioxide, such as silica, calcium, and magnesium. As a result, the filter system 2 can remove impurities from the air, which constitutes the second atmosphere, according to the characteristics of the filter 15b, and is expected to purify the air inside the mobile unit. The purified air, which constitutes the second atmosphere, travels from the air conduit 13 through the flow path inlet 13a and through the induction hole 11c to the inside of the main conduit 11, and is exhausted from the second opening 11b of the main conduit 11.

[0041] [Embodiment 3] Next, with reference to Figures 4A and 4B, a power generation system 3 using the airflow generator 1 will be described as Embodiment 3 of the present invention. Figure 4A is a perspective view of the power generation system 3 to which the airflow generator 1 of Embodiment 1 of the present invention is applied. Figure 4B shows a system diagram of the power generation system 3. The difference from Embodiment 1 is that a rotor blade 16 is provided in the low-pressure chamber 15 and a generator 21 is provided. Here, only the differences from Embodiment 1 will be described. As described above, in Embodiment 1, the low-pressure chamber 15 may not be provided, and the rotor blade 16 may be placed in the flow path inlet 13a of the air conduit 13, and power generation may be performed by rotating the generator with the rotation axis 16a of the rotor blade 16.

[0042] The rotor blade 16 has multiple blade rows, a portion of which is always exposed to a secondary flow Q of a second atmosphere from the flow inlet 13a to the flow outlet 13b, and is capable of rotating around the rotation axis 16a by the secondary flow Q of the second atmosphere. The rotor blade 16 may have blade rows such that the direction of the secondary flow Q is in the direction in which the rotation axis 16a extends, or it may have blade rows such that the direction of the secondary flow Q is perpendicular to the direction in which the rotation axis 16a extends. The rotor blade 16 can have blade rows of various configurations as long as it can rotate around the rotation axis 16a by the secondary flow Q. Figures 4A and 4B show examples of rotor blades having blade rows perpendicular to the direction in which the rotation axis 16a extends.

[0043] The generator 21 is not particularly limited as long as it is of a type that generates electricity by rotation, and is typically a generator comprising a stator 21a and a rotor 21b. One of the stator 21a and rotor 21b is equipped with magnets, and the other of the stator 21a and rotor 21b is equipped with coils. The rotating shaft 16a is connected to the rotor 21b of the generator 21.

[0044] When the airflow generator 1 generates a secondary flow Q of the second atmosphere, the rotor blade 16 rotates due to the secondary flow Q, which in turn rotates the rotating shaft 16a. As the rotating shaft 16a rotates, the rotation of the rotor 21b causes the coil to rotate within the magnetic field, generating induction power within the coil, which is then output to the output line 21c by the generator 21. For example, when the primary flow P of the first atmosphere in the main pipeline 11 is 900 km / h, the secondary flow Q of the second atmosphere in the air conduit 13 is 100 km / h. At this time, the rotational speed of the rotating shaft 16a becomes 1250 rpm, and an output of 0.06 kW is obtained from the generator.

[0045] The power output by the generator 21 can operate various devices on the mobile unit, and by generating power with the airflow generator 1 without using the power required for the operation of the mobile unit, that power can be applied to various devices on the mobile unit.

[0046] [Embodiment 4] Next, with reference to Figures 5A and 5B, a carbon dioxide removal system 4 using the airflow generator 1 will be described as Embodiment 4 of the present invention. Figures 5A and 5B show conceptual perspective views and system diagrams, respectively, of the airflow generator 1 and carbon dioxide removal system 4 of the present invention as Embodiment 4. The carbon dioxide removal system 4 comprises the airflow generator 1, a rotor blade 16, a pump 17, a separation chamber 18, and a liquid container 19.

[0047] In the basic form of Embodiment 1, the flow inlet 13a of the air conduit 13 was exposed to the interior of the moving body, or in a modified form of the basic form of Embodiment 1, the flow inlet 13a of the air conduit 13 was directly connected to the low-pressure chamber 15 and the opening 15a of the low-pressure chamber 15 was exposed to the interior of the moving body. Embodiment 4 differs in that it includes a rotor blade 16 that rotates around a rotation axis 16a in the secondary flow Q to the air conduit 13 inside the low-pressure chamber 15. The airflow generator 1 is the same as in Embodiment 1.

[0048] The rotor blade 16 has multiple blade rows, a portion of which is constantly exposed to a secondary flow Q of a second atmosphere from the flow inlet 13a to the flow outlet 13b, and is capable of rotating around the rotation axis 16a by the secondary flow Q of the second atmosphere. The rotor blade 16 may have blade rows such that the direction of the secondary flow Q is in the direction in which the rotation axis 16a extends, or it may have blade rows such that the direction of the secondary flow Q is perpendicular to the direction in which the rotation axis 16a extends. The rotor blade 16 can have blade rows of various configurations as long as it can rotate around the rotation axis 16a by the secondary flow Q. Figures 5A and 5B show examples of rotor blades having blade rows perpendicular to the direction in which the rotation axis 16a extends.

[0049] Pump 17 comprises a discharge port 172 and a suction port 171 located in a second atmosphere. Pump 17 is a degassing pump, typically a vacuum pump. The rotation shaft 16a of the rotor blade 16 is coupled to an impeller inside the pump 17 so that its rotation is transmitted. Pump 17 is driven by the rotational force of the rotor blade 16 to discharge gas from the second atmosphere drawn in through the suction port 171 through the discharge port 172. Pump 17 can typically be a rotary pump that directly utilizes the rotation around the rotation shaft 16a, but it can also be a positive displacement reciprocating pump that uses a mechanism such as a crank to reciprocate a piston.

[0050] The separation chamber 18 is a chamber in which a separation material 181 is placed and which is divided into two chambers, a front chamber 18a and a rear chamber 18b, by the separation material 181. The front chamber 18a has an opening in part and is exposed to and communicates with the second atmosphere, while the rear chamber 18b communicates with the suction port 171 of the pump 17. The rear chamber 18b is connected to the suction port 171 of the pump 17 and is arranged so that the gas of the second atmosphere that has permeated through the separation material 181 from the front chamber 18a is introduced into the suction port 171 of the pump 17. The separation material 181 is a membrane that selectively permeates carbon dioxide. The separation material 181 is, for example, a polymer material membrane that is a nanoporous film having a large number of nanopores that do not permeate nitrogen and oxygen but selectively permeate carbon dioxide molecules. The separation material 181 is, for example, a polymer film having a large number of nanopores that are larger than the average size of carbon dioxide molecules (0.33 nanometers) and smaller than the average size of nitrogen molecules in air (0.36 nanometers). Furthermore, by making the film thickness 250 nanometers or less, it is possible to selectively transmit carbon dioxide.

[0051] The front chamber 18a is exposed to the second atmosphere inside the mobile body, and the internal pressure of the mobile body is 0.8 atmospheres, for example, in the case of an aircraft cabin. On the other hand, the pressure in the rear chamber 18b is reduced by the pump 17. The pressure difference between the front chamber 18a and the rear chamber 18b causes carbon dioxide in the second atmosphere generated inside the mobile body to pass through the separation material 181. As a result, carbon dioxide is selectively collected in the rear chamber 18b by so-called membrane separation, passing through the separation material 181. On the other hand, other components of air, such as nitrogen, cannot pass through the separation material 181 to the front chamber 18a and either remain in the front chamber 18a or return to the inside of the mobile body.

[0052] The gas of the second atmosphere that has passed through the separation material 181 is introduced to the pump 17 from the suction port 171 via the rear chamber 18b. The gas of the second atmosphere that has passed through the separation material 181 is mostly carbon dioxide, but small amounts of nitrogen and oxygen, which are components of air, also permeate the separation material 181, so the gas of the second atmosphere that has passed through the separation material 181 also contains small amounts of nitrogen and oxygen. The pump 17 discharges the gas of the second atmosphere containing carbon dioxide, which has been drawn in from the suction port 171, from the discharge port 172 using the rotational force transmitted from the rotor blade 16.

[0053] The carbon dioxide removal system 4 includes a liquid container 19 having a liquid 191 that dissolves carbon dioxide inside. Examples of liquids that dissolve carbon dioxide include water and ionic liquids. Any liquid that has high solubility for carbon dioxide is acceptable. The end of the discharge port 172 of the pump 17 is located in the liquid 191 inside the liquid container 19. Alternatively, an inlet pipe may be placed in the carbon dioxide removal system 4, with one end communicating with the discharge port 172 of the pump 17 and the other end located in the liquid in the liquid container 19, allowing a gas of the second atmosphere to pass through the liquid from the inlet pipe. The inlet pipe may be formed as part of the discharge port 172, or as another component connected to the discharge port 172. The gas of the second atmosphere containing carbon dioxide introduced into the liquid container 19 from the discharge port 172 passes through the liquid 191, and the carbon dioxide in the gas of the second atmosphere dissolves in the liquid 191 by so-called solution separation.

[0054] The gas that has passed through the liquid 191 in the liquid container 19 is recirculated into the interior of the mobile body. One way to recirculate the gas that has passed through the liquid 191 into the interior of the mobile body is to place a collector 192 on the top of the liquid container 19 to collect the air that has passed through the liquid 191 from the top of the liquid container 19. The air collected by the collector 192 is recirculated into the interior of the mobile body through a reflux pipe 193 using a reflux device (not shown), and returns to the second atmosphere as fresh gas from which carbon dioxide has been removed.

[0055] This allows the airflow generator 1 to drive the pump 17 without supplying power to the pump 17.

[0056] As described above, in the basic form of the carbon dioxide removal system of Embodiment 4, the rotation shaft 16a of the rotor blade 16 is coupled to the impeller of the pump 17 so as to transmit rotational force. However, as a variation of Embodiment 4, the rotation shaft 16a of the rotor blade 16 is not coupled to the impeller of the pump 17 so as to transmit rotational force, and the rotation shaft 16a of the rotor blade 16 is coupled to the generator 21 so as to Embodiment 3, providing a power generation system 3, and the pump 17 is operated so as to drive the impeller of the pump 17 with the electricity generated by the generator 21 of the power generation system 3 (not shown).

[0057] [Embodiment 5] Next, with reference to Figures 6A and 6B, a carbon dioxide removal system 4 using the airflow generator 1 will be described as Embodiment 5 of the present invention. Figures 6A and 6B show conceptual perspective views and system diagrams, respectively, of the airflow generator 1 and carbon dioxide removal system 4 of the present invention as Embodiment 5. The carbon dioxide removal system 4 comprises the airflow generator 1, a rotor blade 16, a pump 17, a separation chamber 18, and a liquid container 19. In Embodiment 3, the separation chamber 18 uses a separation material 181 to divide the chamber into a front chamber 18a and a rear chamber 18b, and the rear chamber 18b is depressurized so that carbon dioxide selectively passes through the separation material 181. However, Embodiment 5 differs in that a separation pipe 183 is placed in the separation chamber 18, and a pressurized second atmosphere is passed through the separation pipe 183 to selectively separate carbon dioxide from the separation pipe 183. Here, the parts of Embodiment 5 that differ from Embodiments 1 to 4 will be described, and the same parts will be described only as supplementary information.

[0058] Embodiment 5 further includes a compressor 12 in addition to the components of Embodiment 4. The compressor 12 includes an intake port 12a for introducing the second atmosphere into the compressor 12 and an exhaust port 12b for discharging the second atmosphere compressed by the compressor 12. The separation chamber 18 is also equipped with a separation pipe 183, which communicates with the exhaust port 12b and has an exhaust port 183a for discharging from the separation chamber 18.

[0059] In Embodiment 5, the driving force for the compressor 12 is also utilized by the airflow generator 1. Therefore, Embodiment 5 includes two airflow generators 1: a first airflow generator 1a and a second airflow generator 1b. The first airflow generator 1a drives the pump 17, and the second airflow generator 1b drives the compressor 12. The first airflow generator 1a and the second airflow generator 1b have the same structure and mechanism as the airflow generator 1 described in Embodiment 1.

[0060] The first airflow generator 1a comprises a first main conduit 111, a first induction hole 111c, a first air conduit 131, and a first low-pressure chamber 151. The first main conduit 111 has a first opening 111a at one end and a second opening 111b at the other end, and is positioned on the moving body such that a primary flow of a first atmosphere outside the moving body is generated from the first opening 111a to the second opening 111b. The first induction hole 111c is drilled in the wall surface of the first main conduit 111 between the first opening 111a and the second opening 111b. The first air conduit 131 has a flow path inlet 131a at one end and a flow path outlet 131b at the other end. The flow path outlet 131b communicates with the first induction hole 111c, and the flow path inlet 131a is positioned in a second atmosphere inside the moving body. The first low-pressure chamber 151 is equipped with a first rotor blade 161, which is rotatable around a rotation axis 161a by the airflow of the second atmosphere in the first air conduit 131.

[0061] On the other hand, the second airflow generator 1b includes a second main conduit 112, a second induction hole 112c, a second air conduit 132, and a second low-pressure chamber 152. The second main conduit 112 has a first opening 112a at one end and a second opening 112b at the other end, and is positioned on the moving body so that a primary flow of the first atmosphere outside the moving body is generated from the first opening 112a to the second opening 112b. The second induction hole 112c is drilled in the wall surface of the second main conduit 112 between the first opening 112a and the second opening 112b. The second air conduit 132 has a flow path inlet 132a at one end and a flow path outlet 132b at the other end. The flow path outlet 132b communicates with the second induction hole 112c, and the flow path inlet 132a is positioned in the second atmosphere inside the moving body. The second low-pressure chamber 152 is equipped with a second rotor blade 162, which is rotatable around a rotation axis 162a by the airflow of the second atmosphere in the second air conduit 132.

[0062] Valves 141a, 141b, and 141c can be placed in the first opening 111a, the second opening 111b, and the first induction hole 111c of the first main pipeline 111, as needed. Valves 142a, 142b, and 142c can also be placed in the first opening 112a, the second opening 112b, and the second induction hole 112c of the second main pipeline 112, as needed. In addition, valves (not shown) can be placed in the flow inlet 131a and flow outlet 131b of the first air conduit 131, the flow inlet 132a and flow outlet 132b of the second air conduit 132, as needed.

[0063] The first main pipeline 111 and the second main pipeline 112 can typically be configured to communicate in parallel with a common air intake 10a and air outlet 10b, as shown in Figure 6B. Alternatively, the first opening 111a of the first main pipeline 111 and the first opening 112a of the second main pipeline 112 may communicate with separate and different air intakes, and the second opening 111b of the first main pipeline 111 and the second opening 112b of the second main pipeline 112 may communicate with separate and different air outlets (not shown). The first opening 111a of the first main pipeline 111, the second opening 112b of the second main pipeline 112, the second opening 111b of the first main pipeline 111, and the first opening 112a of the second main pipeline 112 are in communication with the outside of the mobile body through openings provided on the mobile body, and various forms can be taken as long as a primary flow P of the first atmosphere from the first opening 111a of the first main pipeline 111 to the second opening 111b of the first main pipeline 111 and a primary flow P from the first opening 112a of the second main pipeline 112 to the second opening 112b of the second main pipeline 112 can occur.

[0064] Pump 17 is the same as in Embodiment 4 and includes an inlet 171 and a discharge port 172. The rotation shaft 161a of the first rotor blade 161 is coupled to an impeller inside the pump 17 so as to transmit rotation. The rotational force of the first rotor blade 161 is transmitted to drive the second atmosphere drawn in from the inlet 171 of the pump 17 to be discharged from the discharge port 172 of the pump 17. The compressor 12, a characteristic configuration of Embodiment 5, includes an intake port 12a and an exhaust port 12b. The rotation shaft 162a of the second rotor blade 162 is coupled to an impeller inside the compressor 12 so as to transmit rotation. The compressor 12 is driven by the rotational force of the second rotor blade 162 to draw in the second atmosphere from the intake port 12a of the compressor 12, compress it, and discharge it from the exhaust port 12b.

[0065] The separation chamber 18 is equipped with a separation tube 183 inside. The separation chamber 18 communicates with the suction port 171 of the pump 17 and collects carbon dioxide that has permeated from the separation tube 183 and introduces it to the suction port 171. The separation tube 183 has one end communicating with the exhaust port of the compressor and the other end communicating with the second atmosphere, and is a tube that selectively permeates carbon dioxide. The separation tube 183 is, for example, a tube formed by forming a thin film of a polymer-based material into a tubular shape. Alternatively, the separation tube 183 is a separation tube formed by creating a polymer-based material separation membrane, which is a nanoporous film having a large number of nanopores, as microtubules with a hollow cross-section having a small radius, and arranging a large number of these into a cluster-like bundle. The meaning of selectively permeating carbon dioxide is that it mainly permeates carbon dioxide, and nitrogen does not permeate at all, or only a small amount if it does. The separation tube 183 has a main gaseous flow along the direction in which it extends, and allows carbon dioxide to permeate in the thickness direction of the polymer-based separation membrane constituting the separation tube 183, which is along the radial direction of the separation tube 183. Therefore, to allow more carbon dioxide to permeate, it is more effective to make the separation tube 183 longer. For example, by forming the separation tube 183 in a spiral shape and housing it inside the separation chamber 18, the separation tube 183 can be housed inside the separation chamber 18 in a small volume.

[0066] When air containing carbon dioxide flows from the exhaust port 12b into the separation tube 183 and is pressurized, only nitrogen, which cannot pass through the polymer separation film layer, passes through the separation tube 183 and is recirculated into the second atmosphere from the outlet 183a. On the other hand, oxygen and carbon dioxide other than nitrogen flow through the polymer separation membrane and seep into the interior of the separation chamber 18, seeping radially through the separation tube 183.

[0067] The carbon dioxide removal system 4, like Embodiment 4, comprises a liquid container 19 having a liquid 191 that dissolves carbon dioxide inside, and an introduction pipe whose one end communicates with the discharge port 172 of the pump 17 and whose other end is located in the liquid 191 of the liquid container 19, allowing the gas of the second atmosphere to pass through the liquid. The gas that has passed through the liquid 191 of the liquid container 19 is recirculated into the inside of the mobile body. That is, the carbon dioxide, along with small amounts of nitrogen and oxygen introduced into the separation chamber 18 by seeping out, is introduced into the pump 17 from the suction port 171 and discharged from the discharge port 172, just like in Embodiment 4. The carbon dioxide is then introduced into the liquid container 19, passes through the liquid 191, and dissolves in the liquid 191 through so-called solution separation, just like in Embodiment 4.

[0068] The carbon dioxide removal system 4, similar to embodiment 4, can also be configured to include a collector that collects gas that has passed through the liquid 191 from the top of the liquid container 19, and a recirculation device that recirculates the gas collected by the collector back into the mobile body. Then, the gas that has passed through the liquid 191 in the liquid container 19 is recirculated back into the mobile body.

[0069] Thus, the carbon dioxide removal system 4 can separate carbon dioxide without requiring mechanical moving parts or electricity by utilizing an airflow generator.

[0070] As described above, in the basic configuration of the carbon dioxide removal system of Embodiment 5, the rotation shaft 161a of the first rotor blade 161 is coupled to the impeller of the pump 17 so as to transmit rotational force, and the rotation shaft 162a of the second rotor blade 162 is coupled to the impeller of the compressor 12 so as to transmit rotational force. However, as a variation of Embodiment 5, a carbon dioxide removal system (not shown) can also be provided without the first rotor blade 161 and the second rotor blade 162, and the power generation system 3 of Embodiment 3 is installed, and the pump 17 and compressor 12 are operated so as to drive the impellers of the pump 17 and compressor 12 with electricity generated by the generator 21 of the power generation system 3.
