[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0044] First, some nouns involved in this application are analyzed:

[0045] Direct Air Capture (DAC): is a carbon reduction technology. Direct air capture technology can capture and store carbon dioxide directly from the air to achieve the reduction effect of removing carbon dioxide from the atmosphere. This carbon reduction technology is challenging because the air contains only 0.04% carbon dioxide. The concentration of carbon dioxide in the air is about 2-3 orders of magnitude lower than other common carbon dioxide capture target sources (such as flue gas produced by energy production and industrial processes). At present, direct air capture technology has received widespread attention as an important and rare means of negative emission carbon reduction.

[0046] Carbon Dioxide Removal (CDR) refers to the process of removing carbon dioxide (CO2) from the atmosphere through human activities and storing it in geological, terrestrial or marine reservoirs or products for a long time. Carbon dioxide removal technology can be used as one of the solutions to reduce greenhouse gas emissions.

[0047] The carbon dioxide removal control method and device, controller, system, and medium provided in the embodiments of the present application are specifically described through the following embodiments. First, the carbon dioxide removal device in the embodiments of the present application is described.

[0048] Figure 1 This is an optional module block diagram of a carbon dioxide removal device provided in an embodiment of the present application, the device comprising:

[0049] A reaction chamber 10, wherein the reaction chamber 10 has an opening;

[0050] A hatch cover 20, the hatch cover 20 is movably connected to the reaction chamber 10, and the hatch cover 20 is used to cover the opening;

[0051] A first electric valve 30, the first electric valve 30 is connected to the hatch cover 20, and the first electric valve 30 is used to control the hatch cover 20 to be opened or closed;

[0052] A gas delivery device 40, the gas delivery device 40 is movably connected to the reaction chamber 10;

[0053] A carbon dioxide adsorption module 50, which is disposed inside the reaction chamber 10;

[0054] Among them, when the hatch 20 is in an open state, the gas delivery device 40 is suspended in the opening, and the gas delivery device 40 blows air toward the opening to form an air inlet, and the gap between the edge of the gas delivery device 40 and the edge of the opening forms an air outlet, so that air flows from the air inlet through the carbon dioxide adsorption module 50 and is discharged from the air outlet; when the hatch 20 is in a closed state, the carbon dioxide adsorption module 50 desorbs carbon dioxide gas.

[0055] The beneficial effects of the embodiment of the present application include but are not limited to: when the hatch cover 20 is in an open state, the gas delivery device 40 is suspended in the opening and blows air into the opening to form an air inlet, and the gap between the edge of the gas delivery device 40 and the edge of the opening forms an air outlet. Air will flow through the carbon dioxide adsorption module 50 from the air inlet and be discharged from the air outlet. When the hatch cover 20 is in a closed state, the carbon dioxide adsorption module 50 desorbs carbon dioxide gas. The embodiment of the present application can control the hatch cover 20 to be opened or closed by the first electric valve 30, that is, whether the hatch cover 20 covers the opening of the reaction chamber 10. Since the air inlet and the air outlet are both located at the opening, a single electric valve, that is, the first electric valve 30, can be used to simultaneously control the opening or closing of the air inlet and the air outlet, and there is no need to use multiple electric valves to separately control the air intake and air outlet processes of the carbon dioxide removal device, thereby improving the air tightness of the carbon dioxide removal device, thereby avoiding the air tightness of the device being insufficient, resulting in the air outside the reaction chamber 10 and the carbon dioxide gas desorbed from the reaction chamber 10 mixing, and improving the purity of the carbon dioxide gas.

[0056] It should be noted that the use of a single electric valve to simultaneously control the opening or closing of the air inlet and outlet reduces the cost of the carbon dioxide removal device, expands the application scenarios and scope of the carbon dioxide removal device, and adapts to carbon capture needs of different scales.

[0057] It should be noted that the hatch cover 20 is in an open state, which means that the hatch cover 20 is not in contact with the opening, and air can enter and exit the reaction chamber 10 through the opening. The hatch cover 20 is in a closed state, which means that the hatch cover 20 covers the opening and is in close contact with the opening, so that the reaction chamber 10 is in an airtight state.

[0058] See also Figure 2 In some embodiments, the first electric valve 30 is connected to the reaction chamber 10 , and specifically may be connected to the outside of the reaction chamber 10 .

[0059] In some embodiments, it should be noted that the gas delivery device 40 is a device, equipment or system for delivering gas. The gas delivery device 40 may include any one of a blower 41, a fan, and a ventilator. A suitable gas delivery device 40 may also be selected according to demand without limitation.

[0060] In some embodiments, the gas delivery device 40 is a blower 41, and a fan blade is provided at the center of the blower 41. When the blower 41 is suspended in the opening, the fan blade rotates to push the air, so that the air flows into the reaction chamber 10 through the fan blade, and thus, the position of the fan blade at the center of the blower 41 in the opening forms an air inlet. After flowing through the carbon dioxide adsorption module 50, the air is discharged from the gap between the edge of the blower 41 and the edge of the opening, and thus, the gap forms an air outlet.

[0061] In some embodiments, the device is placed on a horizontal surface, and the opening is located at the top of the reaction chamber 10;

[0062] The gas delivery device 40 is also used to blow air toward the opening so that the air flows in a first vertical direction at the air inlet and in a second vertical direction at the air outlet; wherein the first vertical direction is perpendicular to the horizontal plane and is a direction from away from the carbon dioxide adsorption module 50 to close to the carbon dioxide adsorption module 50; the second vertical direction is the opposite direction of the first vertical direction.

[0063] The advantage of this embodiment is that the device is placed on a horizontal plane, the opening is located at the top of the reaction chamber 10, and the air flows in and out in a direction perpendicular to the horizontal plane, specifically, it flows in a first vertical direction at the air inlet and flows in a second vertical direction different from the first vertical direction at the air outlet, so as to avoid interference between the inflowing gas and the outflowing gas, increase the flow rate of the gas, and thus improve the efficiency of carbon dioxide adsorption.

[0064] In some embodiments, when the blower 41 is suspended in the opening, the horizontal plane where the cross section of the blower 41 is located is parallel to the horizontal plane where the opening is located, and the blades at the center of the blower 41 and the carbon dioxide adsorption module 50 are located on the same vertical line, thereby ensuring that the air blown in by the blower 41 can fully flow through the carbon dioxide adsorption module 50, thereby improving the carbon dioxide adsorption efficiency. The first vertical direction can be a vertical direction from the blades at the center of the blower 41 to the carbon dioxide adsorption module 50. For example, the shape of the inner wall of the reaction chamber 10 is a cylinder with an opening at the upper end, the carbon dioxide adsorption module 50 is on the central axis of the reaction chamber 10, and the blades at the center of the blower 41 and the carbon dioxide adsorption module 50 are located on the same vertical line, that is, the first vertical direction can be on the central axis of the cylindrical reaction chamber 10. Compared with the first vertical direction, the second vertical direction is closer to the inner wall of the reaction chamber 10, that is, closer to the edge of the opening.

[0065] See also Figure 2 , in some embodiments, the gas delivery device 40 includes a blower 41;

[0066] The edge shape of the blower 41 is circular, and the edge shape of the opening is circular; the shape of the air outlet is a circular ring, and the area ratio of the cross section of the gas delivery device 40 to the cross section of the opening is greater than or equal to 50%.

[0067] The advantage of this embodiment is that the air outlet formed between the edge of the blower 41 and the edge of the opening is in the shape of a circular ring, so as to facilitate the gas to flow out of the reaction chamber 10 and increase the flow speed of the gas, thereby avoiding obstruction of the gas during the flow process, causing the gas that has been adsorbed by the carbon dioxide adsorption module 50 to remain in the reaction chamber 10. In addition, the area ratio of the cross-section of the gas delivery device 40 to the cross-section of the opening is greater than or equal to 50%, so as to avoid the air outlet formed by the gap between the edge of the gas delivery device 40 and the edge of the opening being too large, causing a large amount of air to be discharged from the air outlet before flowing through the carbon dioxide adsorption module 50. In summary, the embodiment of the present application can ensure that the carbon dioxide adsorption module 50 adsorbs carbon dioxide in the air, thereby improving the efficiency of carbon dioxide adsorption.

[0068] In some embodiments, specifically, the shape of the blower 41 may be conical.

[0069] In some embodiments, the reaction chamber 10 is cylindrical, and the reaction chamber 10 includes a side wall, and the side wall is formed with a cavity to accommodate the carbon dioxide adsorption module 50; the gas delivery device 40 is movably connected to the first position of the side wall, and the cabin cover 20 is movably connected to the second position of the side wall, and the first position and the second position are arranged opposite to each other.

[0070] The advantage of this embodiment is that the gas delivery device 40 is movably connected to the first position, the hatch cover 20 is movably connected to the second position, and the first position and the second position are relatively arranged on the side wall of the cylindrical reaction chamber 10, thereby ensuring that there is sufficient space between the gas delivery device 40 and the hatch cover 20, avoiding the hatch cover 20 from colliding with the gas delivery device 40 when opening or closing, thereby improving the safety and reliability of the carbon dioxide removal device.

[0071] See also Figure 3 In some embodiments, the carbon dioxide removal device further includes: a second electric valve 60, the second electric valve 60 includes a cylinder 61, a first pull rod 62 and a second pull rod 63, the cylinder 61 is connected to the first pull rod 62, the first pull rod 62 and the second pull rod 63 are rotatably connected, and the second pull rod 63 is connected to the gas delivery device 40;

[0072] The cylinder 61 is used to control the second pull rod 63 to rotate around the first pull rod 62 so that the gas delivery device 40 is suspended in the opening.

[0073] The advantage of this embodiment is that the second pull rod 63 is controlled by the cylinder 61 to rotate around the first pull rod 62 to drive the gas delivery device 40 connected to the second pull rod 63, so that the gas delivery device 40 is suspended in the opening, so that the gas delivery device 40 performs a blowing action to form an air inlet and an air outlet, thereby achieving the adsorption of carbon dioxide in the air.

[0074] In some embodiments, specifically, an electric push rod may be used instead of the air cylinder 61 as a driving device for the first pull rod 62 and the second pull rod 63 .

[0075] In some embodiments, the carbon dioxide adsorption module 50 includes a carbon dioxide adsorbent, a honeycomb adsorption carrier medium, and a rectifying net;

[0076] Wherein, the carbon dioxide adsorbent is arranged on the honeycomb adsorption carrier medium; the rectifying net is arranged on one end of the honeycomb adsorption carrier medium facing the opening;

[0077] The carbon dioxide adsorbent is used to adsorb carbon dioxide gas in the air, or desorb carbon dioxide gas; the rectifying net is used to prevent the carbon dioxide adsorbent from being carried out of the carbon dioxide adsorption module 50 by the airflow.

[0078] The advantages of this embodiment are that the use of a honeycomb adsorption carrier medium can fully adsorb carbon dioxide in the air; the use of a rectifying net can effectively prevent the carbon dioxide adsorbent from being carried out of the carbon dioxide adsorption module 50 by the airflow, thereby jointly improving the efficiency of carbon dioxide removal.

[0079] In some embodiments, specifically, the adsorbent can be an amine-based solid adsorbent, such as a solid amine adsorbent. In another embodiment, the adsorbent can be coated on a high temperature resistant, porous, and large specific surface area honeycomb adsorption carrier medium, thereby improving the efficiency of carbon dioxide removal.

[0080] See also Figure 4 In some embodiments, the carbon dioxide removal device further comprises:

[0081] A vacuum pump (not shown in the figure), the vacuum pump is connected to the reaction chamber 10, and the vacuum pump is used to evacuate the reaction chamber 10;

[0082] The infrared heating module 70 is disposed inside the reaction chamber 10 and is used to perform infrared heating on the carbon dioxide adsorption module 50 under a vacuum state to desorb carbon dioxide gas.

[0083] The advantage of this embodiment is that the carbon dioxide adsorption module 50 can be heated in a vacuum state by the vacuum pump and the infrared heating module 70 , thereby preventing the residual air inside the reaction chamber 10 from affecting the purity of the carbon dioxide gas desorbed by the carbon dioxide adsorption module 50 .

[0084] It should be noted that in the current air carbon capture process, since it needs to transfer heat through the air medium to heat the carbon dioxide adsorption module 50, the carbon dioxide removal device often contains residual air, which greatly affects the carbon dioxide concentration during the subsequent carbon dioxide collection or reuse. Considering the above problems, the embodiment of the present application uses a vacuum pump to evacuate, and uses an infrared heating module 70 to perform infrared heating on the carbon dioxide adsorption module 50 in a vacuum state inside the reaction chamber 10, thereby improving the purity of the carbon dioxide gas desorbed by the subsequent carbon dioxide adsorption module 50.

[0085] It should be noted that the vacuum state of the embodiment of the present application may refer to a quasi-vacuum state, for example, a state in which the internal air pressure of the reaction chamber 10 is lower than the atmospheric pressure.

[0086] It should be noted that in the embodiment of the present application, the vacuum technology is used to remove the remaining air inside the reaction chamber 10, and the vacuum degree inside the reaction chamber 10 can reach up to 98%, which is much higher than the vacuum degree required for the adsorbent when desorbing carbon dioxide (for example, 82% to 86%). It can be seen that the embodiment of the present application improves the purity of carbon dioxide capture. In the stage of carbon dioxide desorption, photothermal transfer is achieved through the infrared heating module 70 (such as an infrared heating generator), and the temperature change of the carbon dioxide adsorption module 50 in a vacuum-like environment is achieved.

[0087] In some embodiments, it should be noted that the vacuum pump can be connected to the reaction chamber 10 through a vacuum pump interface that is different from the opening, and a suitable vacuum pump interface can be set according to needs, which is not limited in this embodiment of the present application.

[0088] In some embodiments, the carbon dioxide removal device further comprises:

[0089] A gas collecting device connected to a vacuum pump;

[0090] The vacuum pump is also used to collect the carbon dioxide gas desorbed from the carbon dioxide adsorption module 50 into a gas collection device.

[0091] The advantage of this embodiment is that the carbon dioxide gas desorbed by the carbon dioxide adsorption module 50 is collected and stored in a gas collection device, thereby realizing the separation of the carbon dioxide gas from the air and achieving the purpose of removing carbon dioxide.

[0092] Specifically, the gas collecting device may be a gas collecting bottle or a gas collecting bag.

[0093] In some embodiments, the carbon dioxide removal device may further include a gas compressor connected to the vacuum pump and the gas collection device, and used to compress the carbon dioxide gas desorbed by the carbon dioxide adsorption module 50 to collect the compressed carbon dioxide gas into the gas collection device.

[0094] In some embodiments, the carbon dioxide removal device further comprises: an inlet carbon dioxide concentration meter, an outlet carbon dioxide concentration meter, a flow meter, a barometer, and a temperature sensor; the infrared heating module 70 comprises a constant temperature controller;

[0095] The inlet carbon dioxide concentration meter, the outlet carbon dioxide concentration meter, the flow meter, the barometer, and the temperature sensor are all arranged inside the reaction chamber 10; the inlet carbon dioxide concentration meter is used to detect the carbon dioxide concentration at the air inlet; the outlet carbon dioxide concentration meter is used to detect the carbon dioxide concentration at the air outlet; the flow meter is used to detect the gas flow rate inside the reaction chamber 10; the barometer is used to detect the air pressure inside the reaction chamber 10; and the temperature sensor is used to detect the temperature inside the reaction chamber 10;

[0096] The constant temperature controller is used to control the infrared heating module 70 to perform infrared heating on the carbon dioxide adsorption module 50 according to a preset temperature, so that the temperature of the carbon dioxide adsorption module 50 is maintained at the preset temperature.

[0097] The advantage of this embodiment is that various sensors, including an inlet carbon dioxide concentration meter, an outlet carbon dioxide concentration meter, a flow meter, a barometer, and a temperature sensor, are used to detect various state parameters inside the carbon dioxide removal device, thereby improving the real-time performance of the carbon dioxide removal device in removing carbon dioxide and improving the efficiency of carbon dioxide removal.

[0098] In some embodiments, the inlet carbon dioxide concentration meter, the outlet carbon dioxide concentration meter, the flow meter, the barometer, and the temperature sensor are respectively connected to the controller for communication; the controller obtains the signal sent by the above-mentioned sensors, and controls the first electric valve 30 and other modules based on the signal, thereby controlling the state of the carbon dioxide removal device (such as adsorption or desorption) by transmitting the signal, thereby realizing automatic control of the carbon dioxide removal process.

[0099] In some embodiments, the carbon dioxide removal device further includes: a water vapor heating module connected to the reaction chamber 10 ; the water vapor heating module is used to input water vapor into the reaction chamber 10 to heat the carbon dioxide adsorption module 50 with water vapor.

[0100] In some embodiments, it should be noted that the current air carbon capture device often heats the carbon dioxide adsorbent by water vapor, which involves the use of water resources, will cause waste of water resources, and limit its application scenarios. In this regard, the embodiment of the present application adopts an infrared heating module 70 for heating, which avoids the above problems, reduces the use of water resources, optimizes the heat transfer method, has less impact on the environment, and meets the requirements of sustainable development. In another embodiment, the device shell material used in the current air carbon capture device is mainly steel structure material, which limits its application range and temperature change method. In the embodiment of the present application, the shell material of the carbon dioxide removal device can be tempered glass to realize light and heat transfer during infrared heating, overcome the temperature change problem under vacuum state, and help improve the efficiency and performance of the carbon dioxide adsorption module 50 for adsorption.

[0101] It should be noted that the heating method of the carbon dioxide removal device includes at least one of an infrared heating method and a water vapor heating method. In some embodiments, the infrared heating method can be used alone, such as infrared heating the carbon dioxide adsorption module 50 by an infrared heating module 70. In another embodiment, the water vapor heating method can be used alone, such as water vapor heating the carbon dioxide adsorption module 50 by a water vapor heating module. In another embodiment, the infrared heating method and the water vapor heating method can also be used together to desorb carbon dioxide. Among them, the advantages of the water vapor heating method include but are not limited to: the collection speed of carbon dioxide gas is faster, specifically, carbon dioxide is dissolved in water vapor to form carbonic acid, and carbon dioxide gas can be quickly taken away by water vapor. The advantages of the infrared heating method include but are not limited to: overcoming the temperature change problem under vacuum, improving the purity of the desorbed carbon dioxide gas, and reducing the use of water resources, optimizing the heat transfer method, and having less impact on the environment, meeting the requirements of sustainable development.

[0102] It should be noted that conventional carbon dioxide removal devices are usually dual valves, for example, different valves are used to control the air intake and the air outlet. The embodiment of the present application innovatively adopts a single electric valve, which can improve the air tightness compared with conventional equipment; for example, the vacuum degree inside the reaction chamber 10 can reach 96% to 98%. In addition, the embodiment of the present application adopts a single electric valve to reduce energy consumption.

[0103] It should be noted that the carbon dioxide removal device in the embodiment of the present application is relatively simple. On the one hand, the replacement of the adsorbent is relatively convenient; when the hatch 20 is open, the carbon dioxide adsorption module 50 can be directly taken out of the reaction chamber 10 to replace the adsorbent. On the other hand, the intelligent control system is easy to operate. When the carbon dioxide removal device is running, the state of the carbon dioxide removal device can be conveniently and quickly controlled by the intelligent control system. Among them, the intelligent control system has a variety of options, and various state parameters of the carbon dioxide removal device can be adjusted individually. For example, the opening or closing of the gas delivery device 40 (such as a fan) and the control of specific state parameters such as wind speed can be independently controlled by the intelligent control system.

[0104] In some embodiments, the carbon dioxide removal device has a safety protection mechanism to deal with abnormal situations, and the safety protection mechanism may specifically include an overheating protection mechanism and a pressure abnormality release mechanism. In one embodiment, the overheating protection mechanism is implemented by a thermostat in the infrared heating module 70; for example, when the temperature inside the reaction chamber 10 exceeds a preset temperature threshold, such as exceeding 100 degrees Celsius, the thermostat will automatically cool down to avoid overheating, thereby improving the reliability and safety of the carbon dioxide removal device. In another embodiment, the pressure abnormality release mechanism means that a gas pipeline can be set to connect to the reaction chamber 10; in order to avoid the reaction chamber 10 having too low air pressure (such as being in a vacuum state) causing the hatch cover 20 to be difficult to open, before opening the hatch cover 20, gas can be transported to the inside of the reaction chamber 10 through the gas pipeline to pressurize the inside of the reaction chamber 10, so that the pressure difference between the inside and outside of the reaction chamber 10 is reduced, so as to open the hatch cover 20. Specifically, the gas pipeline can also be connected to a gas delivery device, and gas can be delivered to the inside of the reaction chamber 10 through the gas delivery device.

[0105] In some embodiments, the experimental conditions of the carbon dioxide removal device may include: an ambient temperature of 25°C, an ambient humidity of 50% (excluding water vapor blowing and desorption conditions), and a gas flow rate of 1.0 m / min. In the carbon dioxide adsorption module 50, the adsorbent is a solid amine-based adsorbent, and the material of the honeycomb adsorption carrier medium is a cordierite cylindrical module. When conducting an adsorption test, the size of the carbon dioxide adsorption module 50 is 10mmx10mmx10mm; when conducting an overall system test, the size of the carbon dioxide adsorption module 50 is a cylinder with a diameter of 300mm and a height of 150mm.

[0106] In some embodiments, the operating conditions of the carbon dioxide removal device include: an initial carbon dioxide concentration of 450 ppm (parts per million, ppm), a carbon dioxide outlet concentration of 21.6 ppm, and an adsorption efficiency of 95.2%. Specifically, the above data can be the fitted mean of 100 experimental data. It should be noted that after 40 consecutive adsorption-desorption cycles, the adsorption efficiency and desorption efficiency of the carbon dioxide removal device are both maintained above 90%, showing good cycle stability and good adsorbent stability. In some embodiments, specifically, the energy consumption of the carbon dioxide removal device during the adsorption process is about 0.36±0.02 GJ / tCO2 (gigajoules per ton of carbon dioxide), the energy consumption during the desorption process is about 4.12±0.07 GJ / tCO2, and the total energy consumption is about 4.48 GJ / tCO2. In another embodiment, when the carbon dioxide concentration in the air is about 400 ppm and the relative humidity is in the range of 30% to 80%, the adsorption capacity of the carbon dioxide removal device is greater than 1.6 mol / kg (mass molar concentration).

[0107] In some embodiments, it should be noted that the adsorption capacity is used to indicate the total amount of carbon dioxide that can be absorbed by the adsorbent per unit mass (such as kg). The adsorption capacity attenuation fluctuation is used to indicate the proportion of the adsorption capacity that is reduced compared to before the cycle after a predetermined number of adsorption-desorption cycles. Specifically, after the carbon dioxide removal device of the embodiment of the present application cycles 100 times at a relative humidity of 30% to 80%, the adsorption capacity attenuation fluctuation is less than or equal to 15%. For example, if the adsorption capacity attenuation fluctuation is 15%, the initial adsorption capacity is 1 ton, and the adsorption capacity after 100 cycles is 850 kg.

[0108] Specifically, the carbon dioxide removal device can capture about 2.3 kg of carbon dioxide per day.

[0109] Figure 5 is an optional flow chart of the carbon dioxide removal control method provided in the embodiment of the present application, Figure 5 The method is applied to the above-mentioned carbon dioxide removal device, and the method may include but is not limited to steps 101 to 102.

[0110] Step 101, controlling the first electric valve to open the hatch, and controlling the gas delivery device to blow air toward the opening of the reaction chamber, so that air flows from the air inlet through the carbon dioxide adsorption module and is discharged from the air outlet, so that the carbon dioxide adsorption module adsorbs carbon dioxide on the air;

[0111] Step 102: When a predetermined condition is met, the first electric valve is controlled to close the hatch cover, so that the carbon dioxide adsorption module desorbs carbon dioxide gas.

[0112] The beneficial effects of the embodiments of the present application include but are not limited to: controlling the first electric valve to open the hatch, and controlling the gas delivery device to blow air to the opening of the reaction chamber, so that air flows from the air inlet through the carbon dioxide adsorption module and is discharged from the air outlet, so that the carbon dioxide adsorption module performs carbon dioxide adsorption on the air. Since the air inlet and the air outlet are both located at the opening, a single electric valve, that is, the first electric valve, can be used to simultaneously control the opening or closing of the air inlet and the air outlet, and there is no need to use multiple electric valves to separately control the air intake and air outlet processes of the carbon dioxide removal device, thereby improving the air tightness of the carbon dioxide removal device, thereby avoiding the mixing of the air outside the reaction chamber with the carbon dioxide gas desorbed from the reaction chamber due to insufficient air tightness of the device, and improving the purity of the carbon dioxide gas desorbed from the carbon dioxide adsorption module.

[0113] In step 101 of some embodiments, when the gas delivery device is a blower, the blower can be controlled to blow air toward the opening of the reaction chamber. In one embodiment, when the carbon dioxide concentration inside the reaction chamber belongs to a preset atmospheric carbon dioxide concentration threshold range, the carbon dioxide adsorption module performs carbon dioxide adsorption on the air. Specifically, the atmospheric carbon dioxide concentration threshold range can be the normal atmospheric carbon dioxide concentration, such as about 400 ppm (parts per million, ppm), and the specific range can be 350 to 430 ppm. In another embodiment, the air can also enter the reaction chamber under the action of natural wind in a scene with abundant wind energy, which is not limited in the embodiments of the present application.

[0114] In step 102 of some embodiments, the predetermined condition may include: the carbon dioxide concentration value at the air outlet belongs to the preset atmospheric carbon dioxide concentration threshold range. It should be noted that the above predetermined condition indicates that the carbon dioxide concentration at the air outlet has risen to a level close to the carbon dioxide concentration in the normal atmosphere, that is, the adsorbent in the carbon dioxide adsorption module has been fully absorbed by carbon dioxide, and there are no more carbon dioxide attachment points. In some embodiments, the predetermined condition may also include: the time for opening the hatch is greater than the preset time (such as 10 minutes), the user controls the hatch to open, and so on. The predetermined condition may also be set according to the needs, without limitation thereto.

[0115] See also Figure 6 In some embodiments, after step 102, the method may include but is not limited to steps 201 to 202:

[0116] Step 201, controlling the vacuum pump to evacuate the reaction chamber so that the reaction chamber is in a vacuum state;

[0117] Step 202, controlling the infrared heating module to heat the reaction chamber in a vacuum state, so that the carbon dioxide adsorption module performs a desorption action to desorb carbon dioxide gas.

[0118] The advantage of this embodiment is that the residual air inside the reaction chamber is removed by vacuuming, the purity of the carbon dioxide gas desorbed subsequently is improved, and the infrared heating module is used for heating under vacuum state, so as to realize heat transfer (photothermal transfer) through the energy conversion of infrared light, and realize the temperature change of the carbon dioxide adsorption module under vacuum state. It can be seen that the embodiment of the present application can heat the carbon dioxide adsorption module under vacuum state through the vacuum pump and the infrared heating module, so as to avoid the residual air inside the reaction chamber affecting the purity of the carbon dioxide gas desorbed by the carbon dioxide adsorption module.

[0119] In step 201 of some embodiments, the vacuum pump may be controlled to perform vacuuming on the reaction chamber according to a preset vacuuming time. For example, the vacuuming time required for the reaction chamber is 30 seconds.

[0120] It should be noted that, under vacuum conditions, the vacuum degree inside the reaction chamber can reach up to 98%, which is much higher than the vacuum degree required by the carbon dioxide adsorption module during desorption (eg, 82% to 86%).

[0121] In step 202 of some embodiments, a heating action is performed, specifically, the temperature inside the reaction chamber is heated to a preset desorption temperature threshold, wherein the desorption temperature threshold is a suitable temperature for the adsorbent in the carbon dioxide adsorption module that absorbs all carbon dioxide to undergo a desorption reaction. For example, the value range of the desorption temperature threshold may be 90° C. to 100° C. In some embodiments, the temperature inside the reaction chamber is maintained stable by a thermostat controller of the infrared heating module.

[0122] In some embodiments, after step 202, the method includes:

[0123] Controlling the vacuum pump to perform a gas collection action on the carbon dioxide gas so that the carbon dioxide gas enters the gas collection device connected to the vacuum pump;

[0124] When the carbon dioxide concentration value inside the reaction chamber is less than or equal to the preset target carbon dioxide concentration threshold, the process returns to the step of controlling the hatch to open, and controlling the gas delivery device to blow air toward the opening of the reaction chamber.

[0125] The advantage of the embodiments of the present application is that a continuous carbon dioxide removal process is achieved, thereby improving the continuous operation capability of the carbon dioxide removal device.

[0126] See also Figure 7 In one application example, the process of removing carbon dioxide by the carbon dioxide removal device is as follows:

[0127] (1) Room temperature adsorption process, specifically including:

[0128] The first electric valve is controlled to open the hatch, the blower is controlled to be suspended in the opening, and then the blower is controlled to blow air to the opening to form an air inlet, so that air enters the reaction chamber from the air inlet and is discharged from the air outlet, so that the carbon dioxide adsorption module performs carbon dioxide adsorption on the air. At this time, the carbon dioxide in the air flows into the interior of the reaction chamber with the air flow and is adsorbed by the carbon dioxide adsorption module. During the adsorption process, the temperature inside the reaction chamber is room temperature, that is, normal temperature adsorption. In addition, the outlet carbon dioxide concentration of the air outlet is obtained by the carbon dioxide concentration meter; the carbon dioxide concentration of the air outlet is detected by the carbon dioxide concentration meter at the air outlet. When the carbon dioxide concentration at the air outlet belongs to the preset atmospheric carbon dioxide concentration threshold range, the carbon dioxide concentration meter at the air outlet transmits a signal to the controller, the controller controls the blower to stop blowing, and controls the blower to move out of the opening, and then controls the first electric valve to close the hatch, so that the interior of the reaction chamber is in an airtight state.

[0129] (2) Vacuuming process, specifically including:

[0130] The vacuum pump is controlled to evacuate the reaction chamber so that the reaction chamber is in a vacuum state; the pressure inside the reaction chamber is detected by a pressure gauge. When the pressure inside the reaction chamber is less than or equal to the preset vacuum pressure threshold, the pressure gauge transmits a signal to the controller, and the controller controls the vacuum pump to turn off.

[0131] (3) Variable temperature desorption process (also called low temperature desorption process), specifically including:

[0132] The infrared heating module is controlled to heat the reaction chamber in the vacuum state so that the temperature of the reaction chamber belongs to the preset temperature threshold range, so that the carbon dioxide adsorption module performs a desorption action to desorb carbon dioxide gas; the vacuum pump is controlled to collect carbon dioxide gas so that carbon dioxide gas enters a gas collection bag or a collection bottle connected to the vacuum pump. The carbon dioxide concentration value in the reaction chamber is obtained; when the carbon dioxide concentration value in the reaction chamber is less than or equal to the preset target carbon dioxide concentration threshold, the vacuum pump is controlled to be turned off. Specifically, during the variable temperature desorption process, the carbon dioxide concentration value in the reaction chamber increases from about 0 and then decreases to about 0, indicating that the desorption process is completed and carbon dioxide collection is completed. A large-range carbon dioxide concentration meter arranged in the reaction chamber can be used to obtain the carbon dioxide concentration value in the reaction chamber, and the large-range carbon dioxide concentration meter can be arranged at the interface between the vacuum pump and the reaction unit device. The large-range carbon dioxide concentration meter transmits a signal to the controller, and the controller controls the infrared heating module to stop maintaining the constant temperature state in the reaction chamber, and controls the first electric valve to open the hatch cover to carry out the next carbon dioxide removal process.

[0133] It should be noted that the above process of removing carbon dioxide is an alternating cycle process. This application example realizes the conversion of the three processes of room temperature adsorption, vacuuming, and variable temperature desorption.
