[0033] Example

[0034] like Figures 1 to 3 As shown, the utility model proposes a dual-function low eutectic solvent nanoreactor, including a box body 1, the inner wall of the box body 1 is installed with a first partition 11, and a second partition 12 installed on the inner wall of the box body 1 is provided below the first partition 11. The first partition 11 and the second partition 12 divide the interior of the box body 1 into three cavities from top to bottom, namely, a capture chamber, a temporary storage chamber and a conversion chamber. There is a low eutectic solvent in the capture chamber, the temporary storage chamber and the conversion chamber.

[0035] Furthermore, the reactor includes a ventilation assembly 2 disposed within the capture chamber, configured to allow air to pass through the capture chamber. The ventilation assembly 2 includes a first air inlet pipe 21 mounted on the side of the housing 1. The first air inlet pipe 21 communicates with the capture chamber and is located below the liquid level, facilitating the pumping of air into the capture chamber via an air pump. This allows the air to fully contact the deep eutectic solvent, allowing carbon dioxide in the air to be adsorbed into the deep eutectic solvent. A first air outlet pipe 22 is mounted on the side of the housing 1 away from the first air inlet pipe 21. The first air outlet pipe 22 communicates with the capture chamber and is located above the liquid level, facilitating the discharge of air containing adsorbed carbon dioxide from above the liquid level.

[0036] Furthermore, the above-mentioned reactor also includes a catalytic component 3 arranged in the conversion chamber, and the catalytic component 3 is used to introduce catalytic gas and discharge the conversion gas. The catalytic component 3 includes a second air inlet pipe 31 installed on the side of the housing 1. The second air inlet pipe 31 is connected to the conversion chamber and is located below the liquid level, which is convenient for pumping catalytic gas (such as hydrogen) into the conversion chamber through an air pump, so that the catalytic gas and the low eutectic solvent are fully reacted. A second air outlet pipe 32 is installed on the side of the housing 1 away from the second air inlet pipe 31. The second air outlet pipe 32 is connected to the conversion chamber and is located above the liquid level, which is convenient for the discharge of the remaining catalytic gas and the conversion product (methane). Solenoid valves are installed on both the second air inlet pipe 31 and the second air outlet pipe 32. After the solenoid valve is closed, it is convenient for the water pump 42 to transport the low eutectic solvent in the conversion chamber to the capture chamber. At the same time, the low eutectic solvent in the temporary storage chamber enters the conversion chamber through the second lower liquid pipe 51.

[0037] It is worth mentioning that the above-mentioned reactor also includes a conveying mechanism 4 mounted on the housing 1, which is used to drive the deep eutectic solvent to circulate in the capture chamber and the temporary storage chamber. The conveying mechanism 4 includes a first mounting bracket 41 mounted on the side of the housing 1, and a water pump 42 is mounted on the first mounting bracket 41. The position of the water pump 42 is fixed. The output end of the water pump 42 is fixedly connected to a delivery pipe 43, which is used to drive the deep eutectic solvent to circulate in the capture chamber and the temporary storage chamber. One end of the delivery pipe 43 is connected to the capture chamber. Two sets of first liquid down pipes 44 are installed at the bottom of the first partition 11. The temporary storage chamber is connected to the capture chamber through the first liquid down pipes 44. The bottom end of the first liquid down pipe 44 is located below the liquid surface, facilitating the entry of the deep eutectic solvent adsorbed with carbon dioxide in the capture chamber into the temporary storage chamber. A first liquid return pipe 45 is installed on the outside of the housing 1. The first liquid return pipe 45 is connected to the temporary storage chamber and is located below the liquid surface. The input end of the water pump 42 is installed with a liquid inlet pipe 46 to facilitate the circulation of the deep eutectic solvent.

[0038] Furthermore, the above-mentioned reactor also includes a connecting component 5 installed on the housing 1, and the connecting component 5 is used to drive the low eutectic solvent into the conversion chamber. The connecting component 5 includes a second downpipe 51 fixedly connected to the bottom of the second partition 12. The conversion chamber is connected to the temporary storage chamber through the second downpipe 51, so that the low eutectic solvent in the temporary storage chamber can flow into the conversion chamber. The bottom end of the second downpipe 51 is located below the liquid surface. The second downpipe 51 is equipped with an electromagnetic valve to separate the temporary storage chamber from the low eutectic solvent in the conversion chamber, so that the carbon dioxide in the low eutectic solvent can fully react. A second return liquid pipe 52 is also installed on the outside of the housing 1. The second return liquid pipe 52 is connected to the conversion chamber and is located below the liquid surface to facilitate the discharge of the low eutectic solvent after the conversion reaction.

[0039] A switching mechanism 6 is provided on the side of the housing 1. The switching mechanism 6 is used to switch the flow path of the deep eutectic solvent. The switching mechanism 6 includes multiple sets of second mounting brackets 61 mounted on the side of the housing 1. The multiple sets of second mounting brackets 61 are commonly fixedly connected to a reflux block 62. The reflux block 62 is fixedly connected to the first liquid return pipe 45, the liquid inlet pipe 46, and the second liquid return pipe 52. Two sets of first flow channels 63 are defined in the reflux block 62. The two sets of first flow channels 63 are respectively connected to the first liquid return pipe 45 and the liquid inlet pipe 46. The reflux block 62 also defines a second flow channel 64 that is connected to the liquid inlet pipe 46. Both sets of first flow channels 63 are connected to the second flow channel 64. A piston rod 65 is slidably connected to the reflux block 62. The piston rod 65 is located between the two sets of first flow channels 63. After the piston rod 65 moves, it switches the first flow channel 63 to be connected to the second flow channel 64, thereby regulating the water pump 42 to extract the deep eutectic solvent from the temporary storage chamber or the conversion chamber. A connecting rod 66 is fixedly connected to one side of the piston rod 65. The connecting rod 66 is slidably connected to the reflux block 62, and the connecting rod 66 moves synchronously with the piston rod 65. The end of the connecting rod 66 away from the piston rod 65 is fixedly connected to a movable plate 67. A push rod motor 68 is mounted on the side of the reflux block 62. The output end of the push rod motor 68 is fixedly connected to the movable plate 67. When the push rod motor 68 is activated, it drives the movable plate 67 to move, thereby driving the piston rod 65 to slide.

[0040] Finally, an electrical box 7 is installed on the outside of the box body 1. The water pump 42, the push rod motor 68 and the three sets of solenoid valves are all electrically connected to the electrical box 7 to facilitate automatic control of the adsorption and conversion of carbon dioxide.

[0041] In this embodiment, air is first pumped into the first air inlet pipe 21 via an air pump. The air comes into contact with the deep eutectic solvent in the capture chamber, causing the deep eutectic solvent to absorb carbon dioxide from the air. Simultaneously, the water pump 42 is activated, driving the deep eutectic solvent in the temporary storage chamber through the delivery pipe 43 and into the capture chamber. Simultaneously, the deep eutectic solvent in the capture chamber enters the temporary storage chamber through the first downpipe 44. After the deep eutectic solvent circulates, it absorbs a large amount of carbon dioxide in the temporary storage chamber. Subsequently, the push rod motor 68 is activated, driving the movable plate 67 to move, and the piston rod 65 to move via the connecting rod 66, causing the piston rod 65 to block the first flow channel 63 connected to the first return pipe 45. At this point, the water pump 42 is activated, delivering the deep eutectic solvent from the conversion chamber to the capture chamber. Simultaneously, the solenoid valve on the second downpipe 51 opens, and the solenoid valves on the second air inlet pipe 31 and the second air outlet pipe 32 close. Simultaneously, the water pump 42 extracts the deep eutectic solvent from the conversion chamber, while the deep eutectic solvent in the temporary storage chamber enters the conversion chamber. The solenoid valves on the second air inlet pipe 31 and the second air outlet pipe 32 are then opened, the solenoid valve on the second downpipe 51 is closed, and the air pump simultaneously pumps hydrogen into the conversion chamber through the second air inlet pipe 31. The hydrogen reacts with the carbon dioxide adsorbed in the deep eutectic solvent to produce methane, which is then discharged and collected along with the unreacted hydrogen through the second air outlet pipe 32.

[0042] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
