While traditional CO2 emission reduction technologies (such as chemical absorption and membrane separation) are mature, they generally suffer from high energy consumption and secondary pollution. Photocatalytic CO2 reduction technology utilizes solar energy to drive the reaction, converting CO2 into value-added chemicals such as methane (CH4) and methanol (CH3OH), combining environmental friendliness with resource recovery potential, and meeting the low-carbon technology requirements of ISO 14064-1:1918, "Quantification and Reporting Specification for Greenhouse Gas Emissions and Removal." However, current photocatalytic technology still faces challenges such as low efficiency and poor product selectivity. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figure 1 This utility model provides a reduction device for carbon dioxide treatment, comprising:

[0022] The photocatalytic reaction chamber 10 has a catalytic reactor 7 fixedly connected inside it. The feed end of the photocatalytic reaction chamber 10 is connected to a hydrogen supply component and a carbon dioxide waste gas enrichment component. The discharge end of the photocatalytic reaction chamber 10 is connected to a collection tank 11. The feed end and the discharge end are connected through the catalytic reactor 7.

[0023] The detection component includes a monitoring and control unit and a temperature sensor 6 and a pressure sensor 8 installed inside the photocatalytic reaction chamber 10. The temperature sensor 6 and the pressure sensor 8 are electrically connected to the monitoring and control unit, respectively.

[0024] The main function of the catalytic reactor 7 is to perform photocatalytic reduction of carbon dioxide; the main function of the hydrogen supply component is to provide the hydrogen required for the carbon dioxide reduction reaction; the main function of the carbon dioxide waste gas enrichment component is to enrich the carbon dioxide in the factory waste gas and send the carbon dioxide to the photocatalytic reaction chamber 10; the main function of the collection tank 11 is to collect the reaction products; the main function of the temperature sensor 6 is to monitor the temperature in the photocatalytic reaction chamber 10, and the main function of the pressure sensor 8 is to monitor the pressure in the photocatalytic reaction chamber 10. Overall, this invention utilizes the carbon dioxide waste gas enrichment component to enrich the carbon dioxide in the factory waste gas, and then introduces it into the photocatalytic reaction chamber. Under the action of the catalytic reactor, carbon dioxide and hydrogen are efficiently converted into water and high-value-added fuels. The conversion rate is high, effectively treating carbon dioxide in factory waste gas and mitigating the greenhouse effect.

[0025] To further optimize the design, the discharge end of the photocatalytic reaction chamber 10 is connected to the collection tank 11 via the first pipe 21.

[0026] Further optimization of the design: the three side walls of the photocatalytic reaction chamber 10 are made of light-absorbing material, which can absorb light energy to the maximum extent and make the conversion efficiency of carbon dioxide in the chamber reach more than 80%.

[0027] To further optimize the design, a 3DOM single-atom photocatalyst is installed in the catalytic reactor 7. This catalyst is composed of porous nanostructured material components and is used for the photocatalytic reduction of carbon dioxide gas.

[0028] Further optimization of the scheme: the carbon dioxide waste gas enrichment component includes a carbon dioxide desorption device 5, which is connected to a carbon trap 4 via a conveyor belt 23. Several porous material absorption plates 27 are installed on the conveyor belt 23. When the porous material absorption plates 27 move into the carbon trap 4, they are used to absorb carbon dioxide gas in the factory waste gas. When the porous material absorption plates 27 move into the carbon dioxide desorption device 5, they are used to desorb the carbon dioxide in the porous material absorption plates 27. The gas outlet of the carbon dioxide desorption device 5 is connected to the feed end of the photocatalytic reaction box 10.

[0029] like Figure 1 and Figure 2 As shown, after desorption, the carbon dioxide desorption device 5 transports the desorbed porous material absorption plate 27 back to the carbon collector 4 via conveyor belt 23. Simultaneously, the carbon collector 4 transports the collected porous material plate back to the carbon dioxide desorption device 5 via conveyor belt 23, and this process repeats continuously. The carbon dioxide desorbed by the carbon dioxide desorption device 5 is used as a raw material and transported to the photocatalytic reaction chamber 10 via the fourth pipe 24.

[0030] The carbon trap 4 and the carbon dioxide desorption device 5 are respectively provided with openings for the porous material absorption plate 27 to enter. An automatic door (not shown in the figure) is provided at the opening. When the porous material absorption plate 27 is moved out, it automatically closes to ensure the sealing of the carbon trap 4 or the carbon dioxide desorption device 5.

[0031] Further optimization of the scheme: the hydrogen supply component includes an electrolyzer 2, the outlet of which is connected to the feed end of the photocatalytic reaction chamber 10.

[0032] In a further optimized design, a power supply 1 is also provided, which is electrically connected to the electrolytic cell 2 via a wire 19 to provide electrical energy to the electrolytic cell 2. In this embodiment, the power supply 1 is a photoelectrochemical cell.

[0033] like Figure 1 As shown, the photoelectrochemical cell converts light energy into electrical energy during the day or when there is sufficient light to supply electrical energy to the electrolytic cell 2 and stores excess electrical energy. At night or when there is insufficient light, it directly supplies electrical energy to the electrolytic cell 2 through the stored electrical energy.

[0034] Electrolyzer 2 contains anode and cathode as well as water. Hydrogen is produced by electrolyzing water and is transported as raw material to photocatalytic reaction chamber 10 through second pipeline 20.

[0035] To further optimize the design, a condenser 9 is installed on the top of the photocatalytic reaction chamber 10, and the liquid outlet of the condenser 9 is connected to the interior of the electrolytic cell 2.

[0036] The condenser 9 converts the water vapor in the photocatalytic reaction chamber 10 into liquid water, which is then transported back to the electrolyzer 2 through the condenser pipe 3, achieving the effect of water reuse, which is in line with the green and environmentally friendly concept in the project background.

[0037] The design was further optimized by tilting the condenser tube and connecting its lower end to the electrolytic cell 2, which facilitates the smooth entry of condensate into the electrolytic cell 2.

[0038] The scheme is further optimized. The monitoring and control unit includes a central processing unit 15, a temperature sensor 6 and a pressure sensor 8 which are electrically connected to the central processing unit 15, and a display 12 and an alarm 14 are also electrically connected to the central processing unit 15.

[0039] To further optimize the design, the alarm 14 is also equipped with an indicator light 13, and the antenna transmission module 17 interacts with the central processing unit 15 through the interface module. It is internally equipped with a communication control unit 16 and a communication device 18.

[0040] In a further optimized design, the central processing unit 15 is also electrically connected to the carbon dioxide desorption device 5, the electrolyzer 2, the carbon trap 4, the catalytic reactor 7, and the photocatalytic reaction chamber 10 to control the operating status.

[0041] like Figure 1 As shown, temperature sensor 6 accurately measures the temperature in photocatalytic reaction chamber 10 in real time, and pressure sensor 8 accurately measures the gas pressure in photocatalytic reaction chamber 10 in real time. Temperature sensor 6 and pressure sensor 8 feed the monitoring data back to central processing unit 15 so that central processing unit 15 can adjust the relevant equipment to ensure the equipment's carbon dioxide reduction efficiency.

[0042] To further optimize the design, the wires on the central processing unit 15 are protected by conduit 22.

[0043] The scheme is further optimized by also including an exhaust gas collection tank 26, which is connected to the carbon capture device 4 to collect the remaining exhaust gas after carbon dioxide capture.

[0044] like Figure 1 As shown, the carbon trap 4 is connected to the exhaust gas collection tank 26 via a fifth pipe 25.
