Description

Technical Field

[0001] The present invention relates to the field of carbon capture technology, and specifically to a high-pressure air carbon capture and analysis integrated device used in smart greenhouses. Background Art

[0002] In greenhouse cultivation, in order to increase crop yields, it is usually necessary to regularly or irregularly introduce air containing carbon dioxide into the greenhouse. On the one hand, this can increase the temperature in the greenhouse. On the other hand, carbon dioxide, as a raw material for photosynthesis, can promote crop photosynthesis, promote plant growth, and thus increase plant yields.

[0003] Generally, a large amount of high-pressure air is continuously introduced into the adsorption column, and the carbon dioxide in the air is captured by the reaction between the adsorbent and the air. The adsorbed carbon dioxide is then released and introduced into the greenhouse. Because the carbon dioxide content of the same air is 330 mg / L, which is low, if the air flow rate into the adsorption column is too slow, even if it fully reacts with the solid adsorbent, the capture time is too long, the effect is poor, and the expected effect cannot be achieved. Therefore, it is necessary to operate under the premise of a relatively high air flow rate. However, if the air flow rate is too fast, it is easy for the same air to fail to fully react with the same solid adsorbent in a short period of time, which in turn easily leads to the carbon dioxide in the air not being well adsorbed by the solid adsorbent, affecting the overall adsorption effect of the device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the problem in the prior art that the air flow rate entering the adsorption column cannot be controlled, affecting the overall adsorption effect, a high-pressure air carbon capture and analysis integrated device for use in smart greenhouses is now provided.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: a high-pressure air carbon capture and analysis integrated device applied to a smart greenhouse, comprising an air compressor 1, an adsorption column 1, an adsorption column 2 and a vortex blower exhaust pump connected in sequence, the adsorption column 1 and the adsorption column 2 are both placed vertically, the air outlet of the air compressor 1 is connected to the bottom of the adsorption column 1, the top of the adsorption column 1 is connected to the top of the adsorption column 2 through a connecting pipe, the bottom of the adsorption column 2 is connected to the air inlet of the vortex blower exhaust pump, and the bottoms of the adsorption column 1 and the adsorption column 2 are connected to the air compressor 2, the connecting pipes between the air compressor 2 and the adsorption column 1 and the adsorption column 2 are in a "Y" shape, and a high-carbon air outlet is provided on the connecting pipe;

[0006] Each adsorption column is provided with a number of adsorption components distributed at intervals. Each group of adsorption components includes two adsorbent placement plates. The solid adsorbent is placed between two adjacent groups of adsorption components, that is, between the lower adsorbent placement plate of the adsorption component located above and the upper adsorbent placement plate of the adsorption component located below. A heating element is installed between the two adsorbent placement plates. Each group of adsorption components is provided with a number of through holes. Each through hole is equipped with an openable and closable transformer blade. The motor can drive the transformer blade to open and close to adjust the size of the through hole, thereby adjusting the air flow passing through.

[0007] First, the device performs an adsorption cycle. Air compressor 1 works to deliver high-pressure air to the interior of adsorption column 1. The internal variable-pressure blades adjust the opening and closing angles to adjust the air flow inside the adsorption column, allowing the air to fully react with the solid adsorbent on the adsorbent placement plate. The solid adsorbent captures carbon dioxide in the air and then enters adsorption column 2. The solid adsorbent on the adsorbent placement plate in adsorption column 2 captures carbon dioxide in the air again. Finally, the low-carbon air is extracted and discharged outside the greenhouse through the vortex blower exhaust pump.

[0008] Then the analysis cycle is carried out, the heating element works to heat the adsorbent, the air compressor 2 works, the air in the greenhouse enters the interior of the adsorption column 1 and the adsorption column 2, the opening and closing angles of the transformer blades are adjusted, and carbon dioxide is released from the solid adsorbent, thereby discharging the high-carbon air into the greenhouse through the high-carbon air outlet.

[0009] The above technical solution uses adsorption column 1 and adsorption column 2 to extend the contact time between the solid adsorbent and the air, and uses variable pressure blades to dynamically adjust the opening and closing angles to adjust the size of the through hole, change the air flow rate and pressure in the adsorption column, so that the air and the adsorbent are fully in contact, and the carbon adsorption effect per unit time is improved. When the plants in the greenhouse are photosynthesizing, the introduction of high-concentration carbon dioxide air promotes the growth of plant roots and seedlings in the greenhouse, increases leaf thickness, reduces transpiration rate, and improves water use efficiency. At the same time, it promotes plant growth, promotes ethylene biosynthesis, and enhances the antioxidant capacity of plants.

[0010] Furthermore, a humidity detector and a plurality of atomizing nozzles are installed inside the first and second adsorption columns. The atomizing nozzles are distributed at the top of the first adsorption column, the top and bottom of the second adsorption column, and the bottom of each adsorption component. The atomizing nozzles are adjustable and spray water evenly inside the adsorption column. On the one hand, water has a ductility effect and can relatively retain the same air, thereby prolonging the reaction time of the same air and the same solid adsorbent. On the other hand, a relative humidity of 40% to 60% can accelerate the catalysis of the reaction between the same air and the same solid adsorbent, thereby further improving the overall effect of high-pressure air carbon capture and decomposition per unit time.

[0011] Before the adsorption cycle begins, the atomizing nozzle at the bottom of the adsorption component sprays water to make the relative humidity in the adsorption column reach 50% to 60% in the shortest possible time;

[0012] During the adsorption cycle, the atomizing nozzles at the bottom of adsorption column one and the top of adsorption column two spray water to control the relative humidity in the entire adsorption column at 40% to 60%. The direction of the atomizing nozzle spraying water is consistent with the direction of high-pressure air circulation to ensure that the relative humidity in the adsorption column remains stable during the adsorption reaction. Finally, before the end of the adsorption cycle, the water spraying amount of the atomizing nozzle is controlled in advance to reduce the relative humidity in the adsorption column, so that the relative humidity in the device is controlled in advance at 5% to 10%, ensuring the following analysis cycle stage and improving the carbon analysis capacity of the device. During the analysis cycle, the atomizing water spraying amount of the atomizing nozzles at the bottom of adsorption column one and adsorption column two is adjusted to make the relative humidity in the adsorption column reach between 5% and 10%, further improving the carbon analysis effect.

[0013] Furthermore, the high-carbon air outlet is equipped with an exhaust fan. When the device is in the analytical circulation mode, the heating element in the adsorption column heats the solid adsorbent, and the air in the adsorption column rises due to the heat. The small exhaust fan cooperates with the low-power air compressor to achieve energy saving and avoid additional energy loss.

[0014] Furthermore, a thermistor wire is installed at the air outlet of the second air compressor, and a temperature detector is provided on the top of the first adsorption column; when the decomposition cycle starts, the incoming air is heated in advance, and the heating element only needs to be set to a heating temperature of 70°C. With the support of the thermistor wire, the temperature in the adsorption column can reach above 85°C in a short time, reaching the carbon dioxide decomposition temperature. On the one hand, it reduces the heating temperature of the heating element, and on the other hand, it effectively shortens the preheating and heating time, thereby improving the carbon decomposition effect of the device per unit time.

[0015] Furthermore, the air outlets of air compressor 1 and air compressor 2 are both equipped with dust removal filters, and a dust removal filter is also installed between adsorption column 1 and the high-carbon air outlet. The dust removal filter can prevent impurities from entering the adsorption column, thereby effectively preventing impurities from entering the greenhouse and avoiding dust covering crops, affecting photosynthesis and causing diseases.

[0016] Furthermore, an electrically controlled air pressure valve 1 is installed between the air compressor 1 and the adsorption column 1, and between the adsorption column 2 and the vortex fan exhaust pump. An electrically controlled air pressure valve 2 is installed between the high-carbon air outlet, between the air compressor 2 and the adsorption column 1, and between the air compressor 2 and the adsorption column 2. When the electrically controlled air pressure valve 1 is opened, the air is compressed by the air compressor 1 and then enters the adsorption column 1 and the adsorption column 2 in turn. The solid adsorbent adsorbs the carbon dioxide in the air, and the low-carbon air is discharged by the vortex fan exhaust pump. At this time, the device is in an adsorption state. When the electrically controlled air pressure valve 2 is opened, the air is compressed by the air compressor 2 and then divided into two paths, entering the adsorption column 1 and the adsorption column 2 respectively. The heating elements in the adsorption column 1 and the adsorption column 2 heat the adsorbent, and the carbon dioxide is released from the solid adsorbent. The released carbon dioxide and the air enter the shed together with the high-carbon air outlet.

[0017] Furthermore, the air outlet of the air compressor 1, the top of the adsorption column 2 and the bottom of the adsorption column 1 are all provided with air pressure detectors, and the air outlet of the air compressor 1 is installed with an adjustable pressure stabilizer. According to the detection results of the air pressure detector, the air pressure entering the pipeline is dynamically adjusted to achieve dynamic adjustment of high and low air pressures, thereby improving the effect of high-pressure air carbon capture and analysis per unit time.

[0018] Furthermore, a carbon dioxide detector is installed at the air inlet of the vortex blower exhaust pump. When the device is in the adsorption cycle mode, the adsorption capacity of the solid adsorbent decreases with the frequent use of the solid adsorbent. The carbon dioxide detector is set to detect the carbon content in the exhausted air to determine whether a new solid adsorbent needs to be replaced. This design ensures the stable carbon capture capacity of the device.

[0019] Furthermore, the heating element is a graphene heating film, which has a high heat conversion rate and uniform heating.

[0020] The beneficial effects of the present invention are as follows: the present invention utilizes adsorption column 1 and adsorption column 2 to extend the contact time between the solid adsorbent and the air, and utilizes variable pressure blades to dynamically adjust the opening and closing angles to adjust the size of the through hole, thereby changing the air flow rate and pressure in the adsorption column, so that the air and the adsorbent are fully in contact, thereby improving the carbon adsorption effect per unit time.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0032] Example 1:

[0033] like Figure 1-8As shown, the present invention is an integrated device for high-pressure air carbon capture and analysis applied to smart greenhouses, comprising an air compressor 15, an adsorption column 10, an adsorption column 2 11 and a vortex fan exhaust pump 6 connected in sequence, the adsorption column 10 and the adsorption column 2 11 are both placed vertically, the air outlet of the air compressor 15 is connected to the bottom of the adsorption column 10, the top of the adsorption column 10 is connected to the top of the adsorption column 2 11 through a connecting pipe, the connecting pipe is an arc-shaped structure, the bottom of the adsorption column 2 11 is connected to the air inlet of the vortex fan exhaust pump 6, and the bottoms of the adsorption columns 10 and 11 are connected to the air compressor 2 8, the connecting pipes between the air compressor 2 8 and the adsorption columns 10 and 11 are in a "Y" shape, a high-carbon air outlet is provided on the connecting pipe, and the power of the air compressor 15 is greater than that of the air compressor 2 8;

[0034] An electrically controlled air pressure valve 1 31 is installed between the air compressor 1 5 and the adsorption column 1 10, and between the adsorption column 2 11 and the vortex blower exhaust pump 6. An electrically controlled air pressure valve 2 32 is installed between the high carbon air outlet, between the air compressor 2 8 and the adsorption column 10, and between the air compressor 2 8 and the adsorption column 2 11. The gas on and off can be controlled by the electrically controlled air pressure valve 1 31 and the electrically controlled air pressure valve 2 32.

[0035] Each adsorption column is provided with a number of adsorption components distributed at intervals, and each group of adsorption components includes two adsorbent placement plates 1. The solid adsorbent is placed between two adjacent groups of adsorption components, that is, between the lower adsorbent placement plate 1 of the adsorption component located above and the upper adsorbent placement plate 1 of the adsorption component located below. A heating element 2 is installed between the two adsorbent placement plates 1. The heating element 2 is a graphene heating film with a high heat conversion rate and uniform heating. Each group of adsorption components is provided with a number of through holes, and each through hole is equipped with an openable and closable variable pressure blade 14. The motor 18 can drive the variable pressure blade 14 to open and close to adjust the size of the through hole, thereby changing the air flow rate and pressure in the adsorption column, so that the air and the adsorbent are fully in contact, and the carbon adsorption effect per unit time is improved.

[0036] A humidity detector 13 and a plurality of atomizing nozzles 12 are installed inside the adsorption column 10 and the adsorption column 2 11. The atomizing nozzles 12 are distributed at the top of the adsorption column 10, the top and bottom of the second adsorption column, and the bottom of each adsorption component. The atomizing nozzles 12 are adjustable. The atomizing nozzles 12 spray water evenly inside the adsorption column. On the one hand, water has a ductility effect and can relatively retain the same air, thereby prolonging the reaction time between the same air and the same solid adsorbent. On the other hand, a relative humidity of 40% to 60% can accelerate the catalytic reaction between the same air and the same solid adsorbent, thereby further improving the overall effect of high-pressure air carbon capture and decomposition per unit time.

[0037] Before the adsorption cycle begins, the atomizing nozzle 12 at the bottom of the adsorption assembly sprays water to make the relative humidity in the adsorption column reach 50% to 60% in the shortest possible time;

[0038] During the adsorption cycle, the atomizing nozzles 12 at the bottom of the adsorption column 10 and the top of the adsorption column 2 11 spray water to control the relative humidity in the entire adsorption column at 40% to 60%. The direction of the atomizing water spray from the atomizing nozzle 12 is consistent with the direction of high-pressure air circulation to ensure that the relative humidity in the adsorption column remains stable during the adsorption reaction. Finally, before the end of the adsorption cycle, the water spraying amount of the atomizing nozzle 12 is controlled in advance to reduce the relative humidity in the adsorption column, so that the relative humidity in the device is controlled in advance at 5% to 10%, ensuring the following analysis cycle stage and improving the carbon analysis ability of the device. During the analysis cycle, the atomizing water spraying amount of the atomizing nozzles 12 at the bottom of the adsorption column 10 and the adsorption column 2 11 is adjusted to make the relative humidity in the adsorption column reach between 5% and 10%, further improving the carbon analysis effect.

[0039] The high-carbon air outlet is equipped with an exhaust fan 9. When the device is in the analytical circulation mode, the heating element 2 in the adsorption column heats the solid adsorbent, and the air in the adsorption column rises due to the heat. The small exhaust fan 9 cooperates with the low-power air compressor 8 to achieve energy saving and avoid additional energy loss.

[0040] The air outlet of the air compressor 2 8 is installed with a thermal resistance wire 17, and the top of the adsorption column 10 is provided with a temperature detector 7; when the decomposition cycle starts, the incoming air is heated in advance, and the heating element inside the adsorption column only needs to be set to a heating temperature of 70°C. With the support of the thermal resistance wire 17, the temperature inside the adsorption column can reach above 85°C in a short time, reaching the carbon dioxide decomposition temperature. On the one hand, the heating temperature of the heating element is reduced, and on the other hand, the preheating and heating time is effectively shortened, thereby improving the carbon decomposition effect of the device per unit time.

[0041] The air outlets of the air compressor 1 5 and the air compressor 2 8 are both equipped with dust removal filters 15, and a dust removal filter 15 is also installed between the adsorption column 10 and the high-carbon air outlet. The dust removal filter 15 can prevent impurities from entering the adsorption column, thereby effectively preventing impurities from entering the greenhouse and avoiding dust covering crops, affecting photosynthesis and causing diseases.

[0042] The air outlet of the air compressor 15 is provided with an air pressure detector 3 163, the top of the adsorption column 2 11 is provided with an air pressure detector 161, and the bottom of the adsorption column 10 is provided with an air pressure detector 2 162. The air outlet of the air compressor 15 is installed with an adjustable pressure stabilizer 19. The air pressure detector 2 162 and the air pressure detector 3 163 are respectively located on the upstream and downstream sides of the adjustable pressure stabilizer 19. According to the detection results of the air pressure detector, the air pressure entering the pipeline is dynamically adjusted to realize dynamic adjustment of high and low air pressures, thereby improving the effect of high-pressure air carbon capture and analysis per unit time.

[0043] A carbon dioxide detector 4 is installed at the air inlet of the vortex blower exhaust pump 6. When the device is in the adsorption cycle mode, the adsorption capacity of the solid adsorbent decreases with the frequent use of the solid adsorbent. The carbon dioxide detector 4 is set to detect the carbon content in the exhausted air to determine whether a new solid adsorbent needs to be replaced. This design ensures the stable carbon capture capacity of the device.

[0044] Working principle:

[0045] First, the adsorption cycle is carried out. The two electrically controlled air pressure valves 1 31 are opened, and the three electrically controlled air pressure valves 2 32 are closed. The atomizing nozzle 12 sprays water by atomizing. The humidity detector 13 monitors the humidity in the adsorption column and controls the relative humidity in the adsorption column at 40%. The air compressor 1 5 is working, and the high-pressure air is first filtered through the dust removal filter 15, and then passes through the air pressure detector 3 163. The air pressure of the input pipeline is then adjusted by the adjustable pressure regulator 19. The adjustable pressure regulator 19 is repeatedly adjusted according to whether the air pressure detector 2 162 reaches the predetermined pressure value. The air is then transported to the interior of the adsorption column 10. The humidity detector 13 detects the humidity in the column and the atomizing nozzle is adjusted. 12. Accurately control the internal humidity and narrow the humidity range. The variable pressure blade 14 roughly adjusts the opening and closing angle. The air enters the adsorbent placement plate 1 with holes and reacts with the solid adsorbent. The solid adsorbent captures carbon dioxide in the air. The opening and closing angle of the variable pressure blade 14 is finely adjusted according to the air pressure detector 161. The air then passes through the dust removal filter 15 to filter the gas and enters the adsorption column 2 11 through the connecting pipe. The solid adsorbent in the adsorbent placement plate 1 in the adsorption column 2 11 again captures carbon dioxide in the air. Finally, the low-carbon air is extracted and discharged outside the greenhouse through the vortex blower exhaust pump 6. During this process, the carbon dioxide detector 4 continuously detects the carbon dioxide content in the low-carbon air.

[0046] Then, the analysis cycle is carried out. The atomizing nozzle 12 at the bottom of the adsorption column sprays water at an atomizing rate that controls the relative humidity in the adsorption column at 5%. At the same time, the graphene heating film is initially set to a heating temperature of 70°C. The thermal resistor 17 is heated, the three electrically controlled air pressure valves 2 32 are opened, and the two electrically controlled air pressure valves 1 31 are closed. The air compressor 2 8 is operated, and the air is filtered through the dust removal filter 15. The air is input into the interior of the adsorption column 10 and the adsorption column 2 11 through a "Y"-shaped pipe. The humidity detector 13 detects the humidity in the column, and the atomizing nozzle 12 is adjusted to accurately control the internal humidity. The temperature detector 7 is used to detect the temperature in the column, and the temperature of the graphene heating film is adjusted. Accurate heating is performed to ensure that the temperature in the adsorption column reaches the required level. The air pressure detector detects the air pressure in the adsorption column, and the opening and closing angles of the variable pressure blades 14 are adjusted. After the above devices are repeatedly adjusted to achieve the optimal effect, carbon dioxide is released from the solid adsorbent, and the carbon dioxide released from the solid adsorbent is discharged together by the exhaust fan 9, thereby discharging the air containing high concentrations of carbon dioxide into the greenhouse.
