The oxygen concentration monitoring sensor installed on the top of the box will monitor the oxygen concentration in the cylinder in real time;

[0022] S2. Turn on the power supply, start the speed regulating motor, rotate the impeller, draw air from the closed environment outside the air inlet, pass through the desiccant on the mesh plate to absorb moisture, then pass through the filter plate to filter impurities in the air, and transport it to the air diffusion blade chamber and discharge it from the air diffusion holes. The speed regulating motor drives the rotating tube and the air diffusion blades to rotate slowly through the transmission mechanism, so that the air diffusion blades discharge air containing carbon dioxide while rotating.

The activated carbon plate in the collection chamber adsorbs carbon dioxide in the air to collect the carbon dioxide for subsequent use. When needed, the activated carbon plate in the collection chamber is mounted on the support block and heated by the electric heating tube. The heat will cause the carbon dioxide adsorbed on the activated carbon plate to be released. The carbon dioxide is then processed through step S2 to convert it into oxygen for human breathing in the closed environment. Before the release, the push rod is pushed to slide the two sealing plates to the middle position in the slideway of the slide frame, thereby blocking the sealed air inlet and preventing the carbon dioxide from escaping.

[0024] S4. Open the discharge side plate and discharge the reacted material while the diffuser blades rotate, and use the side baffles to prevent the material from falling from both sides.

[0025] S5. Regularly check and replace the desiccant on the slide rail seat to maintain its drying effect. Remove and place the grid plate and filter plate through the first cover plate and the second cover plate for cleaning or replacement. Perform necessary disassembly and maintenance of the exhaust mechanism and transmission mechanism through the rear inspection panel on the back of the box.

[0026] Compared with related technologies, the carbon dioxide capture device and method provided by the present invention have the following beneficial effects:

[0027] 1. Efficient capture and conversion: The present invention adopts a unique reagent (such as sodium peroxide) and carbon dioxide reaction mechanism to achieve the ability to efficiently capture and convert carbon dioxide exhaled by the human body in a closed environment, effectively reducing the carbon dioxide concentration in the closed environment and converting it into oxygen necessary for the human body in the closed environment. The reaction can be carried out at room temperature.

[0028] 2. In addition, the present invention can also adsorb and collect carbon dioxide exhaled by the human body in a closed environment by setting up an activated carbon plate for standby use, and release the carbon dioxide by heating when needed and convert it into carbon dioxide. The activated carbon plate can be recycled, reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] The embodiment of the present invention provides a carbon dioxide capture device, such as Figure 1-12As shown, the carbon dioxide capture device and method include: a box 1 for capturing carbon dioxide exhaled by a human body in a closed environment, wherein a first transverse partition 2 and a second transverse partition 3 are fixedly installed in the box 1 from bottom to top; a cylindrical barrel 4 is fixedly installed on the top of the second transverse partition 3 and the side wall of the box 1, and the space enclosed by the cylindrical barrel 4 and the second transverse partition 3 is used to store granular medicine, which is used to react with carbon dioxide to generate oxygen required for human breathing in a closed environment; an exhaust mechanism arranged on the first transverse partition 2 is used to extract air containing carbon dioxide outside the box 1 and in the closed environment, and transport it to the cylindrical barrel 4.

[0045] In this embodiment, a carbon dioxide capture device is provided, including a box 1 for capturing carbon dioxide exhaled by the human body in a closed environment. A first transverse partition 2 and a second transverse partition 3 are fixedly installed in the box 1 from bottom to top. Such a structural design helps to optimize the spatial layout inside the device. A cylindrical barrel 4 is fixedly installed on the top of the second transverse partition 3 and the side wall of the box 1. The space enclosed by the cylindrical barrel 4 and the second transverse partition 3 is used to store granular medicine. This granular medicine has the special function of reacting with carbon dioxide to generate the oxygen needed for the human body to breathe in a closed environment. The granular medicine in the present invention can be sodium peroxide, and the chemical reaction equation for sodium peroxide to absorb carbon dioxide is:

[0046] 2Na2O2+2CO2→2NaCO3+O2

[0047] In this reaction, sodium peroxide (Na2O2) reacts with carbon dioxide (CO2) to produce sodium carbonate (Na2CO3) and oxygen (O2), which can be achieved at room temperature.

[0048] In order to effectively introduce carbon dioxide from the closed environment into the cylindrical barrel 4 to react with the granular pharmaceutical agent, the present invention provides an exhaust mechanism on the first transverse partition 2. The exhaust mechanism can extract air containing carbon dioxide from the closed environment outside the box 1 and transport it into the cylindrical barrel 4 to react with the pharmaceutical agent.

[0049] Through the above design, the carbon dioxide capture device of the embodiment of the present invention can not only effectively capture carbon dioxide exhaled by the human body in a closed environment, but also convert it into oxygen required by the human body through a granular agent, achieving rational resource utilization and continuous purification of the air in the closed environment. This innovation not only reduces the concentration of carbon dioxide in the closed environment, but also significantly improves air quality, providing personnel with a healthier and more comfortable breathing environment. Furthermore, the device's compact design and simple operation make it particularly suitable for use in special closed environments such as submarines, demonstrating broad application prospects and practical value.

[0050] In a further preferred embodiment of the present invention, a hopper 101 is provided on the top of the box body 1 for adding granular medicine into the cylindrical barrel 4. The hopper 101 is communicated with the space inside the cylindrical barrel 4, and an air inlet 105 is provided on one side of the box body 1 for entering air containing carbon dioxide. The air inlet 105 is set at a height lower than the first transverse partition 2.

[0051] In this embodiment, a hopper 101 is provided on the top of the housing 1. This design facilitates the addition of granular medicine (such as sodium peroxide granules) into the cylindrical barrel 4. The hopper 101 is connected to the space inside the cylindrical barrel 4, ensuring that the medicine can smoothly enter and be stored in the cylindrical barrel 4. At the same time, an air inlet 105 is provided on one side of the housing 1 for the entry of air containing carbon dioxide. The height of the air inlet 105 is lower than that of the first transverse partition 2. This design allows external air to enter the housing 1 more smoothly and be effectively extracted by the exhaust mechanism.

Furthermore, two pulleys 13 are fixedly mounted on the mounting shaft 12 and the wheel shaft 6, respectively. A transmission belt 14 is mounted between these two pulleys 13.

[0056] With this design, the speed regulating motor 11 can drive the mounting shaft 12 to rotate, and then drive the wheel shaft 6 and the impeller 7 to rotate together through the transmission action of the belt 14. This transmission method is not only simple in structure and easy to maintain, but also can achieve stepless speed regulation, so that the exhaust volume of the exhaust mechanism can be flexibly adjusted according to actual needs.

A transmission mechanism is installed at the bottom of the second diaphragm 3. This transmission mechanism includes a reduction gearbox 17 fixedly mounted on the bottom of the second diaphragm 3. The input rod 18 and output rod 21 of the reduction gearbox 17 are both equipped with spline grooves at their ends. A first splined rod 19 is mounted at the top of the mounting shaft 12, meshing with the spline grooves of the input rod 18. This design allows the mounting shaft 12 to drive the input rod 18 in rotation when it rotates. Furthermore, a worm 20 is rotatably mounted on the bottom of the second diaphragm 3. One end of the worm 20 is equipped with a second splined rod 22, meshing with the spline grooves of the output rod 21, thereby achieving a coordinated rotation between the output rod 21 and the worm 20. Finally, a worm wheel 23, fixedly mounted on the rotating tube 15, meshes with the worm 20. Rotation of the worm 20 drives the worm wheel 23 and the rotating tube 15 in rotation.

[0061] In this embodiment, this design not only enhances the structural strength of the housing 1 but also provides a stable sliding mounting base for the mesh panel 25. The retractable mesh panel 25 is slidably mounted on the rail seat 24. This ingenious design allows the user to conveniently replace or replenish the desiccant, ensuring that the air entering the housing 1 is effectively dried. By placing the desiccant on the mesh panel 25, it effectively absorbs moisture from the air, preventing it from reacting with the granular medicine within the cylindrical barrel 4, thereby protecting the granular medicine's performance and extending its service life.

[0064] In addition, a rectangular sealing gasket is installed on the top inner wall of the frame-shaped groove. This design enhances the seal between the rectangular frame 26 and the filter screen 27, ensuring the filtration effect. The frame-shaped airbag 28, installed on the bottom inner wall of the frame-shaped groove, is connected to the air outlet pipe 8 via an inflation tube 29 and is equipped with a valve. When the frame-shaped airbag 28 needs to be inflated, the valve can be opened, the speed control motor 11 can be started, and air can be injected into the frame-shaped airbag 28 to inflate the airbag, thereby forming a seal between the rectangular frame 26 and the filter screen 27.

[0081] The present invention further provides a method for using a carbon dioxide capture device, which is applied to the above-mentioned carbon dioxide capture device and comprises the steps of:

[0082] S1. Add an appropriate amount of granular agent (e.g., sodium peroxide granules) into the cylindrical barrel 4 through the feeding hopper 101. The agent is used to react with carbon dioxide at room temperature to produce oxygen. The oxygen concentration monitoring sensor 104 installed on the top of the box 1 will monitor the oxygen concentration in the cylindrical barrel 4 in real time.

[0083] S2. Turn on the power supply, start the speed regulating motor 11, rotate the impeller 7, draw air from the closed environment outside the air inlet 105, pass the desiccant on the mesh plate 25 to absorb moisture, then pass the filter plate 27 to filter impurities in the air, and transport it to the chamber of the air diffuser 16, and discharge it from the air diffusion holes. The speed regulating motor 11 drives the rotating tube 15 and the air diffuser 16 to rotate slowly through the transmission mechanism, so that the air diffuser 16 discharges air containing carbon dioxide while rotating. The carbon dioxide contacts the granular pharmaceutical and reacts at room temperature to generate oxygen. The oxygen and untreated air are discharged from the feeding hopper 101.

[0084] S3. The oxygen concentration is monitored by the oxygen concentration monitoring sensor 104, and the two solenoid valves are adjusted as needed to allow a portion of the gas to be transported to the collection chamber 38. The activated carbon plate 35 in the collection chamber 38 adsorbs carbon dioxide in the air, thereby collecting the carbon dioxide for subsequent use. When needed, the activated carbon plate 35 in the collection chamber 38 is mounted on the support block 39 and heated by the electric heating tube 40. The heat causes the carbon dioxide adsorbed on the activated carbon plate 35 to be released, and the carbon dioxide is processed through step S2 to convert it into oxygen for human breathing in the closed environment. Before the release, the push rod 43 is pushed to slide the two sealing plates 42 to the middle position in the slideway of the slide frame 41, thereby blocking the sealed air inlet 105 to prevent the carbon dioxide from escaping.

[0085] S4. The reacted material is discharged by opening the discharge side plate 30 and rotating the air diffuser blades 16, and the side baffles 31 are used to prevent the material from falling from both sides.

[0086] S5. Regularly check and replace the desiccant on the slide rail seat 24 to maintain its drying effect. Remove and place the grid plate 25 and the filter screen plate 27 through the first cover plate 44 and the second cover plate 45 to clean or replace them. Perform necessary disassembly and maintenance on the exhaust mechanism and transmission mechanism through the rear inspection panel 46 on the back side of the box body 1.

[0087] This embodiment aims to improve carbon dioxide capture efficiency and provide it for human respiration in a closed environment. The method of use includes: adding a granular agent to the device and monitoring the oxygen concentration; starting the motor to extract air, drying it, filtering it, and then discharging it, allowing the carbon dioxide to react with the agent; adjusting the solenoid valve as needed to collect the carbon dioxide; heating the activated carbon plate 35 to release the carbon dioxide and convert it into oxygen; discharging the reacted material, regularly inspecting and replacing the desiccant, cleaning or replacing the filter plate 27, and performing necessary disassembly and maintenance of the device. This device can improve carbon dioxide capture efficiency while also meeting the human oxygen needs in a closed environment.

The power connection method of each electrical device is an existing mature technology and a well-known technology for people in this field, so no unnecessary details will be given here.

[0090] In summary, compared with related technologies, the present invention uses a unique agent to react with carbon dioxide, achieving efficient capture and conversion in a closed environment, reducing carbon dioxide concentration and converting it into oxygen, and can be carried out at room temperature;

[0091] An activated carbon plate 35 is provided to absorb and collect carbon dioxide, which is then heated for release and conversion when in standby mode. The activated carbon plate 35 can be recycled to reduce costs.
