Description

Carbon dioxide application device Background
[0001] The present disclosure relates to a carbon dioxide application device.
[0002] A carbon dioxide application device for application of carbon dioxide inside agriculture greenhouses to improve the yield and quality of garden plants is publicly known. Meanwhile, agriculture greenhouses are provided with heaters to inhibit a decline of temperature in the night-time. Those heaters combust heavy oil, heating oil, or the like to generate heated air and supply the heated air to the agriculture greenhouses.
[0003] Thus, a carbon dioxide application device that captures and stores carbon dioxide contained in a combustion exhaust gas generated by a heater, and supplies the carbon dioxide into an agriculture greenhouse at any time is being developed.
[0004] The carbon dioxide application device allows a passage of the combustion exhaust gas through a liquid inside a purification tank to be cooled and purified, and then sends the combustion exhaust gas to an adsorption tank with an adsorbent by a blower to make the adsorbent adsorb carbon dioxide.
[0005] The carbon dioxide adsorbed by the adsorbent is, for example, desorbed from the adsorbent during the day, and fed into the agriculture greenhouse.
Summary
[0006] In the carbon dioxide application device as above, installation of the carbon dioxide application device can be facilitated, for example, by forming a purification tank and a blower into a unit in a single housing.
[0007] However, each component of a carbon dioxide application device has different preferred location and environment. Therefore, when various components are assembled into one unit, some of the components may not exhibit their performance sufficiently or additional components may become necessary to ensure the performance.
[0008] In one aspect of the present disclosure, it is preferable to provide a carbon dioxide application device that can improve performance of components of the device with optimized layout.
[0009] One mode of the present disclosure is a carbon dioxide application device configured to capture carbon dioxide contained in a combustion exhaust gas and supply the carbon dioxide into an agriculture greenhouse. The carbon dioxide application device comprises a purification tank, an adsorption tank with an adsorbent disposed therein, and a power portion. The purification tank is configured to store a liquid and allow a passage of the combustion exhaust gas through the liquid. The adsorbent is configured to adsorb carbon dioxide in the combustion exhaust gas. The power portion comprises a blower configured to supply the combustion exhaust gas that has passed through the liquid to the adsorption tank. The purification tank and the power portion are disposed separately from each other.
[0010] According to the aforementioned configuration, since the purification tank and the power portion are separated, the purification tank and the blower can be spaced apart. Thus, regardiess of a position of the purification tank, the blower can be disposed inside the agriculture greenhouse together with the adsorption tank.
[0011] The blower disposed inside the agriculture greenhouse as such limits a decrease in temperature of the combustion exhaust gas heated by the blower due to cooling with outside air. As a result, since the combustion exhaust gas with limited humidity is supplied into the adsorption tank, adsorption capacity and desorption capacity of the adsorbent are improved. Also, generation of rust inside the adsorption tank can be inhibited.
[0012] In one mode of the present disclosure, the purification tank may be disposed outside the agriculture greenhouse. The power portion and the adsorption tank may be disposed inside the agriculture greenhouse. According to the aforementioned configuration, while cooling and purification of the combustion exhaust gas are performed outside the agriculture greenhouse, capacity of the adsorbent can be improved due to limited humidity of the combustion exhaust gas.
[0013] In one mode of the present disclosure, the carbon dioxide application device may further comprise a controller configured to control the power portion. The controller may be disposed outside the power portion. According to the aforementioned configuration, since the blower as a heat source and the controller can be spaced apart, reliability of the controller can be improved. Also, it is no longer necessary to provide an equipment for cooling the controller.
[0014] Another mode of the present disclosure is a carbon dioxide application device that captures carbon dioxide contained in a combustion exhaust gas and supply the captured carbon dioxide into an agriculture greenhouse. The carbon dioxide application device comprises a purification tank, an adsorption tank with an adsorbent disposed therein, a power portion, and a controller. The purification tank is configured to store a liquid and allow a passage of the combustion exhaust gas through the liquid. The adsorbent is configured to adsorb carbon dioxide in the combustion exhaust gas. The power portion comprises a blower configured to supply the combustion exhaust gas that has passed through the liquid to the adsorption tank. The controller is configured to control the power portion. The controller is disposed outside the power portion.
[0015] According to the aforementioned configuration, since the blower as a heat source and the controller can be spaced apart, reliability of the controller can be improved. Also, it is no longer necessary to provide an equipment for cooling the controller.
[0016] In one mode of the present disclosure, the blower may be disposed in a space in the power portion open to an outside of the power portion. According to the aforementioned configuration, an increase in temperature of the blower can be limited without a cooling equipment. As a result, downsizing and cost reduction of the device are facilitated. Brief description of the drawings
[0017] An example embodiment of the present disclosure will be described hereinafter with reference to the accompanying drawings, in which: FIG. 1 is a block diagram schematically showing a configuration of a carbon dioxide application device according to an embodiment; FIG. 2 is a schematic diagram of power portion and a controller of the carbon dioxide application device of FIG. 1. Detailed description of the exemplary embodiments
[0018] [1. First Embodiment] [1-1. Configuration] A carbon dioxide application device 1 shown in FIG. 1 is a device for capturing carbon dioxide contained in a combustion exhaust gas and supplying the captured carbon dioxide into an agriculture greenhouse A.
[0019] The carbon dioxide application device 1 comprises a combustion device 2, a purification tank 3, a recovery tank 4, a power portion 5, an adsorption tank 6, a controller 7, and an adjustment valve 8. The carbon dioxide application device 1 also comprises an exhaust gas flow passage 10, a first receiving path 11, a second receiving path 13, a first supply flow path 15, a second supply flow path 16, and a discharge flow path 17.
[0020] <Combustion devices The combustion device 2 combusts fuels such as heavy oil, kerosene and the like mainly at night to heat air inside the agriculture greenhouse A. The combustion device 2 distributes the combustion exhaust gas outside the agriculture greenhouse A via the exhaust gas flow passage 10. The combustion device 2 may be disposed inside the agriculture greenhouse A, or may be disposed outside the agriculture greenhouse A.
[0021] <Purification tank>
The purification tank 3 cools and purifies a part of the combustion exhaust gas generated in the combustion device 2 with a liquid L1.
[0022] The purification tank 3 stores the liquid L1 inside. Also, the purification tank 5 3is configured to take in the combustion exhaust gas generated in the combustion device 2, and allow a passage of the combustion exhaust gas through the liquid L1.
[0023] The combustion exhaust gas is cooled due to heat exchange with the liquid L1, and simultaneously, a part of components contained in the combustion exhaust gas is removed by a compound contained in the liquid L1. A volume of the liquid L1 stored in the purification tank 3 is smaller than a capacity of the purification tank 3.
[0024] Specifically, the first receiving path 11 is coupled to the purification tank 3, and the combustion exhaust gas is supplied from the first receiving path 11 into the liquid L1. The first receiving path 11 is coupled to the exhaust gas flow passage 10, and takes in the combustion exhaust gas.
[0025] The combustion exhaust gas supplied into the liquid L1 float in the liquid L1 as bubbles. In other words, bubbling is performed in the purification tank 3. The combustion exhaust gas that has passed through the liquid L1 is taken into the recovery tank 4 through the second receiving path 13.
[0026] Preferably, the liquid L1 stored in the purification tank 3 can remove harmful substances, such as sulphides and/or nitrides, contained in the combustion exhaust gas. For example, an aqueous solution of a compound that reacts with sulphides and/or nitrides can be preferably used as the liquid L1.
[0027] A cooling-air flow path (not shown) for cooling the liquid L1 is coupled to the purification tank 3. The liquid L1 is cooled by supplying cooling air into the liquid L1 through the cooling-air flow path.
[0028] <Recovery tank> The recovery tank 4 recovers moisture contained in the combustion exhaust gas that has passed through the liquid L1 in the purification tank 3.
[0029] Specifically, the second receiving path 13 is coupled to the recovery tank 4, and the combustion exhaust gas and the moisture separated from the combustion exhaust gas are supplied from the second receiving path 13 into the recovery tank
4. The combustion exhaust gas that has passed the recovery tank 4 is supplied to the adsorption tank 6 through the first supply flow path 15 and the second supply flow path 16. On the other hand, water L2 separated from the combustion exhaust gas is stored into the recovery tank 4.
[0030] As shown in FIG. 2, the recovery tank 4 has a supply port 4A for supplying the combustion exhaust gas, a discharge port 4B for discharging the combustion exhaust gas, and a cap 4C. The recovery tank 4 can be, for example, a commercial plastic tank.
[0031] The second receiving path 13 is coupled to the supply port 4A. The first supply flow path 15 is coupled to the discharge port 4B. Both the supply port 4A and the discharge port 4B are disposed laterally to the recovery tank 4. The discharge port 4B is located above the supply port 4A.
[0032] The second receiving path 13 and the first supply flow path 15 respectively have a leading end 13A and a leading end 15A that extend in a horizontal direction inside the recovery tank 4. Also, a water surface of the water L2 inside the recovery tank 4 is lower than the leading end 13A of the second receiving path 13. Thus, entry of water inside the recovery tank 4 to the leading end 13A of the second receiving path 13 is inhibited. As a result, the part of the second receiving path 13 disposed inside the recovery tank 4 can be shortened. This facilitates weight saving and cost reduction.
[0033] Also, the leading end 15A of the first supply flow path 15 has a peripheral wall with holes. Further, a filter 15B is wound around the peripheral wall of the leading end 15A to cover the holes. The combustion exhaust gas released from the leading end 13A of the second receiving path 13 into the recovery tank 4 is taken into the leading end 15A of the first supply flow path 15 through the filter 15B.
[0034] The recovery tank 4 can discharge the water L2 inside by leaning its posture with the cap 4C removed. By forming the first supply flow path 15 to be flexible (for example, to have a bellows shape), the water L2 can be discharged with the first supply flow path 15 coupled to the recovery tank 4. Also, the recovery tank 4 may have a drain valve disposed below the leading end 13A of the second receiving path 13. This allows easy discharge of the water L2.
[0035] <Power portion> The power portion 5 has a blower 5A and a frame body 5B.
[0036] The blower 5A is configured to supply the combustion exhaust gas that has passed through the liquid L1 from the recovery tank 4 to the adsorption tank 6. The blower 5A is disposed between the first supply flow path 15 and the second supply flow path 16.
[0037] In an carbon dioxide adsorption process, the inside of the purification tank 3 and of the recovery tank 4 are negatively pressurized (vacuumed) in response to the operation of the blower 5A, and the combustion exhaust gas generated in the combustion device 2 is compressed and transferred to the adsorption tank 6 through the purification tank 3 and the recovery tank 4.
[0038] The frame body 5B holds the blower 5A, the first supply flow path 15, and the second supply flow path 16. Specifically, the blower 5A is mounted on a first floorboard 5C of the frame body 5B. The frame body 5B does not have a side wall that surrounds the blower 5A. In other words, the blower 5A is disposed in a space in the power portion 5 open to an outside of the power portion 5.
[0039] Also, the frame body 5B has a second floorboard 5D disposed below the first floorboard 5C. The recovery tank 4 is mounted on the second floorboard 5D. Thus, the recovery tank 4 is located below the blower 5A.
[0040] <Adsorption tank>
In the adsorption tank 6 shown in FIG. 1, an adsorbent is disposed in the adsorption tank 6. The adsorbent is configured to adsorb carbon dioxide in the combustion exhaust gas. In the carbon dioxide adsorption process, carbon dioxide in the combustion exhaust gas supplied by the blower 5A is adsorbed by the adsorbent. The adsorbent may be implemented, for example, by a hydrophilic porous material such as an activated carbon or zeolite.
[0041] In a carbon dioxide feeding process, a feed air is supplied from a feed-air flow path (not shown) into the adsorption tank 6, and carbon dioxide is desorbed from the adsorbent. The desorbed carbon dioxide is fed into the agriculture greenhouse A through the discharge flow path 17.
[0042] <Controller> The controller 7 is configured to control the operation of the carbon dioxide application device 1. Specifically, the controller 7 is configured to control, for example, the power portion 5 (that is, the blower 5A to operate and to stop), and control a switching valve (for example, solenoid valve) disposed in each flow path to be open and closed.
[0043] The controller 7, as shown in FIG. 2, is located outside the power portion 5. In other words, the controller 7 has a housing separate from the frame body 5B of the power portion 5. Since the controller 7 of the present embodiment is located inside the agriculture greenhouse A, high weather resistance is not required as compared to a case outside the agriculture greenhouse A. Thus, the housing of controller 7 can be plastic, which allows the housing to be light.
[0044] In the present embodiment, the controller 7 is disposed above the power portion 5. However, the controller 7 may be disposed below the power portion 5, or may be spaced apart from the power portion 5.
[0045] <Adjustment valve> The adjustment valve 8 is configured to adjust the pressure in the purification tank 3 and the recovery tank 4. The adjustment valve 8 is configured to block the flow of gas from the adsorption tank 6 into the recovery tank 4 after the operation of the blower SA is stopped. In other words, the adjustment valve 8 inhibits the pressure inside the purification tank 3 and the recovery tank 4 from being increased after the operation of the blower 5A is stopped.
[0046] The adjustment valve 8 is disposed in the first supply flow path 15, that is, in the upstream side of the blower 5A in the direction of flow of the combustion exhaust gas. The adjustment valve 8 is located above the discharge port 4B of the recovery tank 4 and below an intake port 5E of the blower 5A.
[0047] The adjustment valve 8 may be implemented, for example, by a check valve. Alternatively, a gate valve, a globe valve, a ball valve or the like may be used as the adjustment valve 8. In this case, the adjustment valve 8 may be held open during the carbon dioxide adsorption process, and the adjustment valve 8 may be closed manually or by the controller 7 after the operation of the blower 5A is stopped. The adjustment valve 8, which is implemented by the check valve, can simplify the configuration of the adjustment valve 8, and thus can reduce the cost.
[0048] In the present embodiment, the adjustment valve 8 is oriented so that the combustion exhaust gas flows in the horizontal direction. The adjustment valve 8 may be oriented so that the combustion exhaust gas flows in a vertical direction.
[0049] <Layout of each component> Inthe carbon dioxide application device 1, the purification tank 3, the power portion 5, and the adsorption tank 6 are disposed separately from each other.
[0050] Specifically, as shown in FIG. 1, the purification tank 3 is disposed outside the agriculture greenhouse A. Also, the power portion 5, the controller 7, and the adsorption tank 6 are disposed inside the agriculture greenhouse A.
[0051] In addition, it is preferable that the power portion 5 may be disposed closer to the adsorption tank 6 than the purification tank 3. In other words, the purification tank 3, the power portion 5, and adsorption tank 6 may be disposed so that a length of the second supply flow path 16 is smaller than a total length of the second receiving path 13 and the first supply flow path 15. This can improve performance of the adsorption tank 6.
[0052] [1-2. Effects] According to the embodiment described above in detail, the following effects can be achieved. (1a) Separation of the purification tank 3 and the power portion 5 enables the purification tank 3 and the blower 5A to be spaced apart. Thus, regardless of a position of the purification tank 3, the blower 5A can be disposed inside the agriculture greenhouse A together with the adsorption tank 6.
[0053] The blower 5A disposed inside the agriculture greenhouse A as such limits a decrease in temperature of the combustion exhaust gas heated by the blower 5A due to cooling with outside air. As a result, since the combustion exhaust gas with limited humidity is supplied to the adsorption tank 6, adsorption capacity and desorption capacity of the adsorbent are improved. Also, generation of rust inside the adsorption tank 6 can be inhibited.
[0054] (1b) The purification tank 3 disposed outside the agriculture greenhouse A improves cooling effect of the combustion exhaust gas by outside air. Further, while cooling and purification of the combustion exhaust gas are performed outside the agriculture greenhouse A, the capacity of the adsorbent can be improved by humidity limitation of the combustion exhaust gas.
[0055] (1c) The controller 7 disposed outside the power portion 5 enables the blower 5A as a heat source and the controller 7 to be spaced apart. As a result, reliability of the controller 7 can be improved. Also, it is no longer necessary to provide an equipment for cooling the controller 7.
[0056] (1d) Since the blower 5A is disposed in a space in the power portion 5 open to an outside of the power portion 5, an increase in temperature of the blower SA can be limited without a cooling equipment. As a result, downsizing and cost reduction of the device is facilitated.
[0057] [2. Other embodiments]
Although the embodiment of the present disclosure has been described above, the present disclosure is not limited to the aforementioned embodiment, but may be embodied in various forms.
[0058] (2a) In the carbon dioxide application device of the aforementioned embodiment, the blower may not be disposed in a space in the power portion open to an outside of the power portion. For example, the blower may be disposed in a space surrounded by side walls.
[0059] (2b) In the carbon dioxide application device of the aforementioned embodiment, the adjustment valve may not be disposed above the discharge port of the recovery tank and below the intake port of the blower. Also, the discharge port and the supply port of the recovery tank may not be disposed laterally to the recovery tank.
[0060] (2c) It may be possible to divide a function of one element in the above- described embodiment to a plurality of elements, or to integrate functions of a plurality of elements into one element. The configurations in the above-described embodiments may be partly omitted. At least part of the configuration of the above- described embodiments may be added to or replaced with the configuration of other embodiments described above. Any form that falls within the scope of the technical idea defined by the language of the appended claims may be an embodiment of the present disclosure.
