Description

Technical Field

[0001] The invention relates to the field of carbon dioxide capture, and in particular to an indoor carbon dioxide capture system for a high-rise building. Background Art

[0002] An indoor CO2 capture system is a system used to reduce indoor CO2 concentrations by capturing CO2 from the air through physical or chemical methods, thereby improving indoor air quality.

[0003] Existing indoor carbon dioxide capture systems often require fans to drive gas flow to bring air into the capture unit to adsorb and fix carbon dioxide. After adsorption is completed or saturated, the capture module needs to be desorbed. On the one hand, using fans to introduce air into the capture module for fixation, heating the capture module and evacuating it for desorption all consume a lot of energy. On the other hand, high-rise buildings, such as office buildings, require a relatively quiet office environment with dense crowds and high carbon dioxide concentrations in the air. The use of fans will cause noise and other problems. In addition, the indoor carbon dioxide capture process has multiple stages, and there is no unified method for switching between stages, making it difficult to effectively control, which in turn affects the final air purification effect.

[0070] Example

[0071] The present application embodiment provides a high-rise building indoor carbon dioxide capture system, such as Figure 1 As shown, it is applied to a method for capturing indoor carbon dioxide in a high-rise building;

[0072] like Figure 2 As shown, the system includes: a main control unit 1 and an airflow power unit 2, a carbon capture unit 3, and a plurality of airflow circulation units 4 that are communicatively connected to the main control unit 1;

[0073] The method comprises: S100, dividing the whole day into one or any multiple of a first time period, a second time period and a third time period according to light intensity;

[0074] Specifically, in some embodiments of the present application, the first time period is a strong light period, the second time period is a weak light period, and the third time period is a non-light period;

[0075] That is, the overall light intensity of the first time period is greater than the overall light intensity of the second time period, and the overall light intensity of the second time period is greater than the overall light intensity of the third time period.

[0076] S200, switching the system to different working modes for air purification according to the time period of the system;

[0077] For example, in some embodiments of the present application, the first time period can be set to 10:00-16:00, the second time period can be set to 16:00-18:00; the third reference time can be set to 18:00-10:00 the next day, so as to optimize the orderly operation of various working modes of the indoor air purification system of high-rise buildings, meet the temperature requirements when each mode is running, and achieve good air purification effect.

[0078] S300, through the system switching between different working modes, to complete the purification of indoor air in high-rise buildings;

[0079] Specifically, in some embodiments of the present application, the working mode of the indoor air purification system of a high-rise building includes one or any multiple of a carbon fixation mode, a carbon removal mode, and a cooling mode;

[0080] The first period corresponds to the carbon fixation mode, the second period corresponds to the decarbonization mode, and the third period corresponds to the cooling mode;

[0081] Generally speaking, the indoor air purification system of high-rise buildings needs to go through carbon fixation mode, decarbonization mode and cooling mode, and is divided into the first period, the second period and the third period according to the lighting characteristics of different time periods throughout the day. It can make more reasonable use of solar energy to create usage conditions suitable for different working modes, achieve a good conversion of matter and energy, and thus optimize the carbon fixation and decarbonization effects of the indoor air purification system of high-rise buildings.

[0082] S400, in the first period, the carbon capture unit, the airflow circulation unit and the airflow power unit are connected, and an updraft is formed through the airflow power unit, so that the air in each airflow circulation unit is driven by the updraft and passes through the carbon capture unit to fix carbon dioxide and then enters the airflow power unit;

[0083] S500, in the second period, the connection between the carbon capture unit and the airflow circulation unit and the airflow power unit is cut off, the carbon capture unit is vacuum treated, and the carbon capture unit is heated to desorb the carbon dioxide fixed in the carbon capture unit;

[0084] It can be understood that the carbon capture unit 3 is heated to provide sufficient heat conditions for the decarbonization working mode to achieve a good decarbonization effect, while the vacuum treatment of the carbon capture unit 3 provides a good vacuum environment for the desorption of carbon dioxide to improve the desorption efficiency of carbon dioxide.

[0085] S600, in the third period, cooling the carbon capture unit after desorption.

[0086] During the third period, the ambient temperature decreases, and the carbon capture unit 3 is cooled by heat exchange between the carbon capture unit 3 and the external environment.

[0087] Furthermore, if Figure 1 As shown, the airflow power unit 2 includes a channel housing 21 and a heating module 22, and the channel housing 21 and the heating module 22 are attached to the outer wall of a high-rise building to form an airflow channel 23 for airflow;

[0088] Specifically, in some embodiments of the present application, the heating module 22 is arranged in contact with the outer wall of a high-rise building, and the channel shell 21 is sleeved on the heating module 22 to form an air flow channel 23 located between the channel shell 21 and the heating module 22; and the channel shell 21 is made of transparent material to facilitate sunlight to pass through and shine on the heating module 22, and be absorbed by the heating module 22.

[0089] Preferably, the high-rise building has a sunny side and a shady side, and the airflow power unit 2 is arranged from top to bottom on the outer wall of the sunny side of the high-rise building;

[0090] The air circulation unit 4 is divided according to the indoor space of the high-rise building, and the carbon capture unit 3 is arranged on one side of the air circulation unit 4 close to the air flow channel 23, and the carbon capture unit 3 is used to connect the air flow channel 23 with the air circulation unit 4;

[0091] In the first period, the carbon capture unit 3 , the air circulation unit 4 and the air flow channel 23 of the air flow power unit 2 are connected, and the heating module 22 of the air flow power unit 2 absorbs sunlight to heat the air to form an ascending airflow in the air flow channel 23 .

[0092] It can be understood that after the heating module 22 absorbs sunlight, it heats the air in the airflow channel 23. The air rises due to the heat under the action of the "chimney effect", and the air pressure in the airflow channel 23 drops, forming an air pressure difference between each airflow circulation unit 4 and the airflow power unit 2. Under the influence of the air pressure difference, the air flows from each airflow circulation unit 4 (i.e., indoors in the building) through the carbon capture unit 3 to the airflow power unit 2, completing the adsorption and fixation of carbon dioxide by the carbon capture unit 3. There is no need to set up a fan for driving, which reduces energy consumption and is not easy to generate noise; and the airflow power unit 2 is attached to the outer wall of a high-rise building, which reduces the floor space and can adapt to application scenarios with limited space.

[0093] It can be understood that, in combination with the above content, high-rise buildings use rising airflow to drive air into the carbon capture unit 3 for carbon dioxide fixation, which can effectively reduce energy consumption. The airflow power unit 2 is attached to the outer wall of the sun-facing side of the high-rise building and is arranged from top to bottom. At the same time, it can heat the airflow. Compared with the situation where the heating module 22 is arranged at the bottom, the effectiveness and stability of the indoor air purification system of the high-rise building are enhanced.

[0094] Furthermore, if Figure 3 and Figure 6 As shown, the airflow power unit 2 includes a heat medium interlayer 25, and the heat medium interlayer 25 is arranged close to the heating module 22 of the airflow power unit 2. The side of the heat medium interlayer 25 away from the ground is connected to the heat exchange branch pipe 311 in the carbon capture unit 3 through the steam inlet valve 251. The heat exchange branch pipe 311 is connected to the side of the heat medium interlayer 25 close to the ground through the drain valve 252 to form a heat medium circulation channel;

[0095] Specifically, in some embodiments of the present application, the heat medium filling amount is determined based on heat calculation, and the ratio of the heat medium volume to the capacity of the heat medium interlayer 25 is between 0.5 and 0.7;

[0096] For example, the capacity of the heat medium interlayer 25 may be 10 cubic meters, so the heat medium volume occupies 6 cubic meters, and the remaining space is used for the subsequent vacuum treatment of the carbon capture unit 3 .

[0097] The heat medium in the heat medium interlayer 25 heats the carbon capture unit 3 through the heat medium circulation channel;

[0098] Furthermore, the heat medium in the heat medium interlayer 25 heats the carbon capture unit 3 through the heat medium circulation channel. The specific process includes:

[0099] In the first period, the steam inlet valve 251 and the drain valve 252 are closed, the conduction between the heat medium interlayer 25 and the heat exchange branch pipe 311 is cut off, and the heating module 22 absorbs sunlight and heats the heat medium interlayer 25 to vaporize part of the heat medium. The gaseous heat medium is located on the side of the heat medium interlayer 25 away from the ground, and the liquid heat medium is located on the side of the heat medium interlayer 25 close to the ground.

[0100] In the second period, the steam inlet valve 251 and the drain valve 252 are opened, the heat medium interlayer 25 and the heat exchange branch pipe 311 are connected, and the gaseous heat medium enters the heat exchange branch pipe 311 through the steam inlet valve 251, releases heat to heat the carbon capture unit 3, and the vaporized heat medium after heating condenses into liquid heat medium; the liquid heat medium falls back into the heat medium interlayer 25 through the drain valve 252.

[0101] It can be understood that the above arrangement realizes the effective recycling of heat medium and utilizes the form conversion characteristics of heat medium. There is no need to set up an additional heat medium conveying structure, which reduces energy loss and use. In the first period, solar energy heats the heat medium interlayer 25, vaporizes part of the heat medium, stores the heat energy converted by solar energy, and the continuously vaporized heat medium increases the gas pressure in the space of the heat medium interlayer 25. After the steam inlet valve 251 is opened, the heat medium in the form of high-pressure steam enters the heat exchange branch pipe 311 under the influence of the gas pressure difference, thereby reducing energy consumption.

[0102] After releasing heat in the heat exchange branch pipe 311 by latent heat of vaporization, the gaseous heat medium is converted into liquid heat medium. The liquid heat medium falls back into the heat medium interlayer 25 due to gravity, and no conveying mechanism is required. This realizes low-energy or energy-free heat medium circulation and transportation, reducing energy usage.

[0103] The steam inlet valve 251 and the liquid discharge valve 252 are connected to the main control unit 1 for communication, so as to realize intelligent control of the steam inlet valve 251 and the liquid discharge valve 252 .

[0104] Furthermore, if Figure 8 As shown, the air circulation unit 4 is provided with an air purification module 41, the air purification module 41 is connected to the air intake valve 32 of the carbon capture unit 3, and the air purification module 41 is provided with a capture material 411 for capturing VOC gas or ammonia;

[0105] Among them, VOC (Volatile Organic Compounds) refers to organic chemicals that easily evaporate and enter the air at normal temperature and pressure. There are many types of VOC gases, which are usually composed of elements such as carbon, hydrogen, and oxygen. Some VOC gases may have adverse effects on the environment and human health.

[0106] For example, VOC gases include acetone and isoprene produced during human breathing, squalene secreted by human sebaceous glands, lactic acid and butyric acid contained in human sweat, etc.;

[0107] Of course, there is no limitation on the specific composition of the VOC gas.

[0108] The capture material 411 can be made of activated carbon and can be detachably arranged in the air purification module 41 so as to be replaced when the capture material 411 is saturated with adsorption.

[0109] Of course, there is no limitation on the specific capture material 411 , as long as it can adsorb VOC gas or ammonia.

[0110] The air purification module 41 can effectively capture VOC gas or ammonia, reduce the emission of VOC gas or ammonia, so as to reduce the impact on the environment and air quality and improve the ambient air quality; and the air purification module 41 can pre-treat the air before the air enters the carbon capture unit 3 to remove VOC gas or ammonia, thereby reducing the burden on the subsequent carbon capture unit 3 and improving the working efficiency and carbon capture effect of the entire system.

[0111] Furthermore, if Figure 7 As shown, the system is also provided with a light monitoring module 5;

[0112] Optionally, the light monitoring module 5 may be a fiber optic sensor, an optical sensor array, or a combination of a photodiode, a photoelectric sensor, or a photoresistor;

[0113] The light monitoring module 5 is used to monitor the sunlight irradiation on the heating module 22 of the airflow power unit 2, and is connected to the main control unit 1 for communication, and sends the irradiation information related to the heating module 22 to the main control unit 1;

[0114] The method further includes: acquiring sunlight information, the sunlight information including the illumination start time and / or the illumination angle;

[0115] Of course, sunlight information can also include light intensity;

[0116] Predict the end time of illumination based on the illumination start time and illumination angle;

[0117] Specifically, in some embodiments of the present application, a lighting time prediction model is pre-trained, and the lighting time prediction model outputs the lighting end time by inputting the lighting start time and the lighting angle;

[0118] For example, the input illumination time may be 6:00, the illumination angle may be due east, and the output predicted illumination end time is 18:00;

[0119] Based on the sunlight information and the end time of the sunlight, one or more of the first time period, the second time period and the third time period are adjusted.

[0120] Specifically, in some embodiments of the present application, after predicting the illumination end time based on the illumination start time and illumination angle, the start and end time of the first period is adjusted first, and the second and third periods are adjusted in sequence based on the start and end time of the first period to ensure a sufficient first period to optimize the air purification effect;

[0121] As another example, assuming that the high-rise building is located in the northern hemisphere, when the irradiation direction is northeast, the first time period will be advanced accordingly, and the second and third time periods will be advanced accordingly. Specifically, the first time period can be set to 9:30-15:30, and the second time period can be set to 15:30-17:30; the third time period can be set to 17:30-9:30 the next day; when the irradiation direction is southeast, the first time period will be postponed accordingly, and the second and third time periods will be postponed accordingly; to match the operating temperature conditions required by the carbon capture unit 3, and optimize the carbon fixation, decarbonization and cooling effects of the carbon capture unit 3.

[0122] Furthermore, if Figure 3 and Figure 7 As shown, the system is further provided with a heat compensation module 8 connected to the heating module 22, and the heat compensation module 8 is located on a side of the airflow power unit 2 close to the ground;

[0123] The heat compensation module 8 is respectively connected to the light monitoring module 5 and the main control unit 1 for communication;

[0124] The method further includes: when in the first period, obtaining real-time light intensity through the light monitoring module 5;

[0125] If the acquired light intensity is lower than the first preset light intensity value, the heat compensation module 8 is activated to heat the air in the air flow channel 23 to promote the formation of an upward air flow in the air flow channel 23 .

[0126] For example, in weather with weak sunlight, such as rainy or cloudy weather, the heat provided in the first period is insufficient to form an updraft;

[0127] At this time, if the light intensity is lower than the first preset light intensity, the heat compensation module 8 can be activated to heat the air and / or the heat medium in the heat medium interlayer 25 to form an upward airflow, enhance the stability of the upward airflow, and reduce dependence on external energy;

[0128] Specifically, in some embodiments of the present application, the heat compensation module 8 may be an electric heating device;

[0129] Of course, there is no limitation on the specific heat compensation module 8 .

[0130] As another example, the first preset light intensity can be measured by the radiation energy or illumination of the light source, and of course there is no limitation on the specific measurement method; the first preset light intensity can be set according to the energy or illumination for forming the rising airflow;

[0131] For example, if the solar radiation heat required for heating is 37 kJ, and the solar radiation heat that can be obtained by the current light intensity is lower than 37 kJ, which may be 15 kJ, then the heat compensation module 8 needs to be started to heat the heat medium or the air.

[0132] Furthermore, if Figure 2 , Figure 3 and Figure 6 As shown, the carbon capture unit 3 includes: a capture module 31, an air intake valve 32, an exhaust valve 33, an air extraction valve 34 and a vacuum pump 35;

[0133] One end of the air outlet of the capture module 31 is connected to an exhaust valve 33 for connecting to the air flow channel 23 of the air flow power unit 2; one end of the air inlet of the capture module 31 is connected to an air intake valve 32 for connecting to the air flow circulation unit 4; the capture module 31 is also connected to an exhaust valve 34, and the exhaust valve 34 is connected to a vacuum pump 35 for improving the desorption efficiency;

[0134] The air inlet valve 32, the air exhaust valve 33, the air extraction valve 34 and the vacuum pump 35 are respectively connected to the main control unit 1 for communication;

[0135] In the first period, the air intake valve 32 and the air exhaust valve 33 are opened to connect the carbon capture unit 3, the air circulation unit 4 and the air flow channel 23, and the air extraction valve 34 and the vacuum pump 35 are closed;

[0136] The heating module 22 arranged on the outer wall of the high-rise building absorbs the heat from the sun and heats the air in the air flow channel 23. The air rises due to the heat, and the air containing high concentration of carbon dioxide in the air flow circulation unit 4 continuously passes through the capture module 31. After the carbon dioxide is absorbed by the air in the capture module 31, the air enters the air flow channel 23 through the exhaust valve 33.

[0137] In the second period, the air intake valve 32 and the air exhaust valve 33 are closed to cut off the connection between the carbon capture unit 3 and the air circulation unit 4 and the air flow channel 23, and the air extraction valve 34 and the vacuum pump 35 are opened to vacuum the carbon capture unit 3;

[0138] After the solid amine particles 313 are saturated with adsorption and / or the carbon dioxide concentration in the air in the air circulation unit 4 reaches a suitable range, the decarbonization process begins, and the heat medium in the heat medium interlayer 25 enters the heat exchange branch 311 of the capture module 31 through the exhaust valve. The heated gaseous heat medium liquefies and releases heat in the heat exchange branch 311 in the capture module 31, heating the solid amine particles 313 and providing the heat required for decarbonization. The capture module 31 is evacuated by the vacuum pump 35 to improve the desorption efficiency; the liquefied liquid heat medium is affected by gravity and falls back into the heat medium interlayer 25 through the drain valve 252.

[0139] The heat medium of the gaseous heat medium provides the necessary temperature conditions through the heating module 22, which helps to efficiently release the captured carbon dioxide in the desorption mode; the configuration of the exhaust valve 34 and the vacuum pump 35 can evacuate the inside of the capture module 31, thereby improving the efficiency of the desorption process, and also helps to drive the carbon dioxide generated by the desorption to be discharged from the capture module 31;

[0140] In the third period, the carbon capture unit 3, the air circulation unit 4 and the air flow channel 23 are connected by opening the air intake valve 32 and the air exhaust valve 33 to accelerate the cooling of the carbon capture unit 3.

[0141] It can be understood that during the third period, the lower ambient temperature at night is utilized to achieve natural cooling depending on the ambient temperature.

[0142] Opening the air intake valve 32 and the exhaust valve 33 at the same time helps to promote the flow of air, improve the air heat exchange efficiency, and further increase the cooling speed of the carbon capture unit 3.

[0143] Furthermore, if Figure 5 As shown, the capture module 31 includes: solid amine particles 313, heat exchange branch pipes 311 and a plurality of heat exchange fins 312;

[0144] Both ends of the heat exchange branch pipe 311 are respectively connected to the heat medium interlayer 25 in the air flow power unit 2, and the heat exchange branch pipe 311 runs through the capture module 31;

[0145] Specifically, in some embodiments of the present application, one end of the heat exchange branch pipe 311 is connected to the heat medium interlayer 25 through the steam supply pipe 314, and one end of the heat exchange branch pipe 311 is connected to the heat medium interlayer 25 through the liquid return pipe 315;

[0146] The steam supply pipe 314 is provided with a steam inlet valve 251 , and the liquid return pipe 315 is provided with a liquid discharge valve 252 .

[0147] Heat exchange fins 312 are arranged around the axial direction of the heat exchange branch pipe 311. The heat exchange fins 312 are arranged in an orderly manner to form a mesh heat exchange area 310 centered on the heat exchange branch pipe 311. The solid amine particles 313 are located in the accommodation space surrounded by the heat exchange fins 312 and the heat exchange branch pipe 311.

[0148] Specifically, in some embodiments of the present application, the distribution of the heat exchange fins 312 and the heat exchange branch pipes 311 divides the internal space of the capture module 31 into a plurality of accommodation spaces, and each solid amine particle 313 is respectively arranged in a different accommodation space.

[0149] More specifically, in some embodiments of the present application, a heat transfer component made of a three-dimensional fin tube is further provided on the heat exchange fin 312 and / or the heat exchange branch tube 311 .

[0150] The meshed heat exchange area 310 can significantly improve the efficiency of the heat exchange process and achieve better heat transfer. The distribution of the heat exchange fins 312 and the heat exchange branches 311 optimizes the spatial layout, thereby increasing the heat exchange area while occupying a relatively small volume. This facilitates the solid amine particles 313 to effectively contact the heat exchange fins 312 and / or the heat exchange branches 311, thereby achieving sufficient heating of the solid amine particles 313 and also helping to achieve uniform heating of the solid amine particles 313 in the capture module 31.

[0151] Furthermore, if Figure 5 and Figure 7 As shown, the system is further provided with a carbon dioxide concentration detection module 6, which includes a first detector 61 arranged at the air inlet of the carbon capture unit 3 and a second detector 62 arranged at the air outlet of the carbon capture unit 3;

[0152] The first detector 61 and the second detector 62 may be infrared absorption type carbon dioxide detectors, chemical sensor type carbon dioxide detectors, or electrochemical sensor type carbon dioxide detectors.

[0153] Of course, there is no limitation on the specific types of the first detector 61 and the second detector 62 .

[0154] The carbon dioxide concentration detection module 6 is in communication connection with the main control unit 1;

[0155] The method further includes:

[0156] In the first period, if it is detected that the difference in carbon dioxide concentration detected by the first detector 61 and the second detector 62 is not greater than a preset value, the control system switches from the working mode corresponding to the first period to the working mode corresponding to the second period.

[0157] In the above situation, when the solid amine particles 313 of the carbon capture unit 3 reach a saturated state and the indoor carbon dioxide concentration reaches a predetermined normal level, the carbon capture unit 3 automatically switches the operation mode, thereby improving the intelligence level of the carbon capture unit 3.

[0158] Exemplarily, the preset value can be 30 ppm. If the first detector 61 detects a carbon dioxide concentration of 300 ppm, and the second detector 62 detects a carbon dioxide concentration of 289 ppm; then at this time, the difference in carbon dioxide concentrations detected by the first detector 61 and the second detector 62 is not greater than the preset value, and the control system switches from the carbon fixation mode corresponding to the first time period to the decarbonization mode corresponding to the second time period.

[0159] Of course, there is no limitation on the specific size of the preset value.

[0160] In other embodiments of the present application, when in the second time period, if it is detected that the difference in carbon dioxide concentration detected by the first detector 61 and the second detector 62 is not less than a preset value, the control system switches from the working mode corresponding to the second time period to the working mode corresponding to the third time period.

[0161] Furthermore, if Figure 4 As shown, the heating module 22 includes: a heat insulation layer 222, a heat conductive medium layer 224, a light-to-heat conversion layer 223 and a heat exchange strengthening component 221;

[0162] The insulation layer 222 is arranged on a side close to the outer wall of the high-rise building, the heat exchange reinforcement component 221 is arranged on a side close to the air flow channel 23, the light-to-heat conversion layer 223 is attached to the insulation layer 222, and the heat conductive medium layer 224 is located between the light-to-heat conversion layer 223 and the heat exchange reinforcement component 221.

[0163] Specifically, in some embodiments of the present application, the heat exchange reinforcement component 221 has a good light transmittance property, so that sunlight can pass through the heat exchange reinforcement component 221 and the photothermal conversion layer 223, and absorb solar energy through the photothermal conversion layer 223 and transfer heat to the heat conductive medium layer 224. The heat conductive medium layer 224 transfers heat to the air through the heat exchange reinforcement component 221 to heat the air to form an ascending airflow, and also to transfer heat to the heat medium interlayer 25 through the heat exchange reinforcement component 221. The heat medium in the heated heat medium interlayer 25 serves as the main source of heat for the decarbonization mode of the capture module 31.

[0164] Exemplarily, the heat medium may be water, and the photothermal conversion layer 223 may be realized by coating a photothermal material; the thermal conductive medium layer 224 may contain a thermal conductive medium, such as water or oil.

[0165] The multi-layer structure of the heating module 22 can play the role of heat insulation and heat absorption, and reduce the amount of heat entering the room; wherein, the photothermal conversion layer 223 is located between the heat insulation layer 222 and the heat conductive medium layer 224, which can effectively capture and convert solar energy, improve the photothermal conversion efficiency, and use the converted heat energy to heat the heat medium in the heat medium interlayer 25 and the heat conductive medium layer 224; the heat exchange reinforcement member 221 is arranged on the side close to the air flow channel 23, and after absorbing the heat of the heat conductive medium layer 224, it can enhance the exchange of air and heat, and improve the thermal utilization efficiency of the system; so that the hot air in the air flow channel 23 forms a relatively obvious temperature difference with the outdoor environment, causing the hot air in the air flow channel 23 to rise, and after the hot air rises, a low pressure area is formed at the original position, causing the air of each air flow circulation unit 4 to flow toward the direction of the air flow channel 23 to replenish the air flow channel 23, and continue this process, forming the effect of indoor air being drawn into the air flow channel 23; the heat insulation layer 222 is located on the side close to the outer wall of the high-rise building, which can effectively prevent heat from entering the interior of the building and reduce the indoor temperature of the building.

[0166] Furthermore, the heating module 22 includes a plurality of heat absorbing submodules (not shown in the figure), and the heat absorbing submodules are arranged from top to bottom along the height direction of the high-rise building; each air circulation unit 4 is arranged in sequence along the height direction of the high-rise building, and is located on one side of the air flow channel 23;

[0167] A high-rise building includes a high-rise area and a low-rise area, and the area of ​​the heat-absorbing submodule located in the high-rise area is not less than the area of ​​the heat-absorbing submodule located in the low-rise area;

[0168] The area of ​​the heat absorption submodule in the high-rise area is larger than that in the low-rise area, which helps to capture more solar radiation in the high-rise area of ​​the building. The high-rise area is usually exposed to more light. By increasing the heat absorption area in the high-rise area, the heat load can be balanced at different heights of the building and the effective utilization rate of sunlight can be improved. By setting a larger area of ​​heat absorption submodule in the high-rise area of ​​the building, it helps to improve the effective utilization rate of the heat absorption submodule and also helps to reduce manufacturing costs.

[0169] The heat absorption submodule has an irradiation surface for receiving sunlight. The heat absorption submodule is also provided with an angle adjustment device 24, which is connected to the main control unit 1 and is used to adjust the direction of the irradiation surface according to the angle of sunlight.

[0170] By setting an angle adjustment device 24 to adjust the direction of the irradiation surface, and cooperating with the continuous or intermittent monitoring of the light monitoring module 5, the irradiation surface is opposite to the direction of sunlight, so that the light incident angle is 90 degrees or approximately 90 degrees, which can maximize the amount of sunlight received and improve the light-to-heat conversion efficiency. It can automatically adjust according to the angle of sunlight so that the heat absorption sub-module can obtain the best light at different times and seasons, thereby enhancing the environmental adaptability of the heat absorption sub-module, and thus also helping to enhance the "chimney effect" and provide a better airflow driving force.

[0171] Furthermore, if Figure 1 and Figure 7 As shown, the system is also provided with a photovoltaic panel module 7, which is located in the high-rise area of ​​the high-rise building and is used to convert solar energy into electrical energy to supply power to the system.

[0172] The photovoltaic panel module 7 is located in the high-rise area, which can effectively receive the energy of sunlight, convert solar energy into electrical energy, and provide clean electricity; it enriches the diversity of energy sources of the carbon dioxide capture system and improves the stability of energy supply of the indoor air purification system of high-rise buildings;

[0173] The electricity generated by the photovoltaic panel module 7 can better meet the building's energy needs for heating the gas in the air flow channel 23 and driving the vacuum pump 35, improve the overall energy utilization efficiency, adapt to the use needs of the indoor air purification system in high-rise buildings, and rely on clean energy to achieve the overall energy consumption of the carbon dioxide capture system.

[0174] Furthermore, if Figure 7 As shown, an energy storage module 9 connected to the photovoltaic panel module 7 is also provided.

[0175] The photovoltaic panel module 7 can generate electricity during the day, and the energy storage module 9 can store excess electricity for use at night or during periods of insufficient sunlight such as cloudy days, which helps the carbon dioxide capture system to obtain a more stable power supply at different times.

[0176] The present invention proposes a high-rise building indoor carbon dioxide capture system, and verifies the required energy and air purification effect.

[0177] Taking a high-rise building carbon capture project as an example, the annual carbon dioxide capture capacity is required to be 1 t, and the daily adsorption is calculated as 6 hours. The required air volume is calculated to be 900m³ / h, the capture module size is 1mx1m, the capture module thickness is 100mm, the desorption temperature is 110℃, and the solar energy is used as the heat source. The required radiation area is 362.3㎡ (the external wall area of ​​20mx20m can meet the requirements), and the required heat medium interlayer thickness is 6mm. Detailed design calculation data are shown in Table 1:

[0182] Specifically, the airflow power unit 2 includes a channel shell 21 and a heating module 22. The heat from the sun is used to enhance the airflow through the heating module 22, thereby improving the energy efficiency of the system, reducing dependence on external energy, reducing system energy consumption, and helping to keep the environment quiet. According to different time periods, the system is switched to different modes to adapt to environmental conditions of different working modes, thereby improving the intelligence and automation level of the system, thereby improving the effective utilization of energy and optimizing the indoor air purification steps and purification effects of high-rise buildings.
