[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1 As shown;

[0027] A porous filtration membrane device for reducing carbon emissions includes a liquid storage box 1, a porous filter membrane 11 fixedly connected to the top surface inside the liquid storage box 1, and a gas-liquid separation membrane 12 fixedly connected inside the liquid storage box 1. The gas-liquid separation membrane 12 is located below the porous filter membrane 11, and a threaded cap 13 is threadedly connected to the bottom of the liquid storage box 1.

[0028] In this implementation plan: carbon dioxide emitted from vehicle exhaust will exacerbate the greenhouse effect, so it is necessary to reduce carbon dioxide emissions from exhaust. On this basis, a carbon reduction mechanism 3 is added.

[0029] It should be noted that: This device is installed at the exhaust outlet of the car's exhaust pipe, connecting the exhaust pipe to the interior of the intake pipe 24, so as to absorb and treat the carbon dioxide emitted from the exhaust pipe. The upper surface of the liquid storage box 1 is evenly provided with air holes, so that the gas filtered by the porous filter membrane 11 can be discharged into the interior of the liquid storage box 1. The function of the porous filter membrane 11 is to intercept the carbon dioxide in the mixed gas entering the liquid storage box 1, so that the carbon dioxide can be fully absorbed by the alkaline solution in the liquid storage box 1. The surface of the porous filter membrane 11 is in contact with the surface of the fixed tube 21 and the inner wall of the liquid storage box 1. The function of the gas-liquid separation membrane 12 is to block the solution in the liquid storage box 1 below the gas-liquid separation membrane 12, so as to prevent the solution in the liquid storage box 1 from spilling out of the device due to shaking during the movement of the car. The gas-liquid separation membrane 12 has corrosion-resistant properties to prevent it from being corroded by the alkaline solution in the liquid storage box 1.

[0030] Furthermore:

[0031] like Figures 1 to 8 As shown:

[0032] Based on the above: The carbon reduction mechanism 3 includes a fixed tube 21 fixedly connected to the top surface inside the liquid storage box 1, a rubber sealing sleeve 22 fixedly connected inside the fixed tube 21, and a storage ring 23 slidably connected inside the rubber sealing sleeve 22. An air inlet pipe 24 is fixedly connected to a through circular groove opened on the upper surface of the fixed tube 21.

[0033] A concentration detector 25 and a gas volume detector 26 are mounted on the surface of the air inlet pipe 24. An electric push rod 27 is mounted on the upper surface of the liquid storage box 1. One end of the output shaft of the electric push rod 27 passes through the liquid storage box 1 and the rubber sealing sleeve 22, and the output shaft of the electric push rod 27 is slidably connected to the liquid storage box 1 and the rubber sealing sleeve 22. The electric push rod 27 is in contact with one of the storage rings 23. A processor 28 is mounted on the surface of the liquid storage box 1. The processor 28 is electrically connected to the concentration detector 25, the gas volume detector 26 and the electric push rod 27 respectively through wires.

[0034] The storage ring 23 is ring-shaped with an annular groove on its vertical curved surface. The friction between the storage ring 23 and the rubber sealing sleeve 22 is relatively large, which allows the storage ring 23 to remain stationary against gravity inside the rubber sealing sleeve 22.

[0035] In this implementation scheme: the vehicle exhaust gas purified by the three-way catalytic converter enters the intake manifold 24 through the exhaust pipe, and then enters the reservoir 1 through the intake manifold 24. The carbon dioxide in the exhaust gas is absorbed by the sodium hydroxide solution inside the reservoir 1, and precipitates out as carbon-containing precipitate inside the reservoir 1. During the process of the exhaust gas being passed from the exhaust pipe into the intake manifold 24, the concentration of carbon dioxide in the exhaust gas is detected by a concentration detector 25 installed on the intake manifold 24, and the gas volume detector 26 calculates the volume of exhaust gas entering the intake manifold 24. This data is then processed by the processor 28. When the sodium hydroxide in the solution inside the liquid storage box 1 is about to be exhausted, the electric push rod 27 pushes the storage ring 23 inside the rubber sealing sleeve 22 downward, so that the storage ring 23 at the bottom of the rubber sealing sleeve 22 falls into the interior of the liquid storage box 1, thereby dissolving the sodium hydroxide solid inside the storage ring 23 into the water in the liquid storage box 1, thus maintaining the continuous adsorption of carbon dioxide by the device. The deformation direction of the rubber sealing sleeve 22 is restricted by the inner wall of the fixed tube 21 and the surface of the air inlet tube 24, so that the storage rings 23 inside the rubber sealing sleeve 22 are not easily detached from the rubber sealing sleeve 22 under the action of gravity.

[0036] It should be noted that the rubber sealing sleeve 22 is tubular in shape and has an annular groove on its surface. The rubber sealing sleeve 22 is made of rubber. When the storage ring 23 is inside the rubber sealing sleeve 22, the storage ring 23 is isolated from the solution inside the storage box 1. This prevents the sodium hydroxide solid inside the annular groove of the storage ring 23 from dissolving prematurely in the water inside the storage box 1, thus affecting the device's judgment of the sodium hydroxide balance. This could lead to an increase in pressure inside the storage box 1, potentially causing damage to the device. There are at least two storage rings 23. When only one storage ring 23 remains inside the rubber sealing sleeve 22, the processor 28 can issue a prompt to promptly clean the inside of the liquid storage box 1 and replenish the sodium hydroxide inside the liquid storage box 1. Adjacent storage rings 23 are in contact with each other. The concentration detector 25 is a carbon dioxide concentration detector, facilitating the detection of carbon dioxide concentration in the exhaust gas entering the inlet pipe 24. The gas flow detector 26 is a gas flow monitoring instrument, facilitating the calculation of the gas volume entering the inlet pipe 24, thereby facilitating the processor... 28 calculates the carbon dioxide content introduced into the liquid storage box 1, thereby controlling the extension and retraction of the electric actuator 27. This also prevents leakage of the solution from the liquid storage box 1 due to accidental damage. When diluting the leaked solution, it prevents the supersaturated sodium hydroxide in the solution from continuing to dissolve during the dilution process, thus avoiding further damage. The concentration detector 25 and gas volume detector 26 on the surface of the air inlet pipe 24 are located outside the liquid storage box 1 to avoid corrosion by the alkaline solution inside. The portion of the air inlet pipe 24 located inside the liquid storage box 1 has its surface... The surface of the rubber sealing sleeve 22 is tightly fitted to restrict the deformation direction of the rubber sealing sleeve 22 in conjunction with the fixing tube 21. The bottom end of the air inlet pipe 24 is located below the liquid surface of the solution in the liquid storage box 1, so that the exhaust gas blown out from the air inlet pipe 24 can fully contact the solution in the liquid storage box 1. When only one storage ring 23 remains inside the rubber sealing sleeve 22, the pushing amount of the electric push rod 27 is only enough to expose the annular groove of the last storage ring 23 to the solution in the liquid storage box 1, thereby making it difficult for the solution in the liquid storage box 1 to overflow out of the device along the rubber sealing sleeve 22.

[0037] Furthermore:

[0038] In an optional embodiment, the bottom end of the air inlet pipe 24 is rotatably connected to a diffuser head 29 via a bearing 1. A diffuser hole 291 is fixedly connected to the surface of the diffuser head 29 through a circular groove 2. An actuating rod 210 is provided on the surface of the diffuser hole 291. A fixed bearing 211 is fixedly connected to the bottom surface of the fixed pipe 21. A driven rod 212 is fixedly connected to the surface of the outer ring of the fixed bearing 211. A driven rod 215 is fixedly connected to the surface of the driven rod 212. A fixed bearing 213 is fixedly connected to the inner wall of the liquid storage box 1. A scraper 214 is fixedly connected to the inner ring surface of the fixed bearing 213. A driven rod 216 is fixedly connected to the bottom surface of the scraper 214.

[0039] In this implementation scheme: when the exhaust gas is blown into the interior of the diffuser head 29 through the inlet pipe 24, the gas enters the solution in the liquid storage box 1 through the diffuser hole 291, allowing the carbon dioxide and alkaline solution to react more fully. The diffuser head 29 rotates around the inlet pipe 24 through the diffuser hole 291, causing the actuating rod 210 to move along with the rotation of the diffuser head 29. When the actuating rod 210 moves to contact the driven rod 212 on the bottom surface of the fixed bearing 211, it drives the driven rod 212 to rotate around the fixed pipe 21. Through the cooperation of the driven rod 215 and the driven rod 216, the scraper plate 214 on the fixed bearing 213 rotates around the fixed pipe 21. During this process, the scraper plate 214 continuously scrapes the bottom surface of the gas-liquid separation membrane 12 to prevent the bottom surface of the gas-liquid separation membrane 12 from being blocked by particulate carbon, precipitated sodium hydroxide, precipitated sodium carbonate and other substances.

[0040] It should be noted that the air diffuser holes 291 are arranged in an even array on the surface of the air diffuser head 29, with each group containing several air diffuser holes 291. The axes of the air diffuser holes 291 are all tangent to the surface of the air diffuser head 29, and the multiple groups of air diffuser holes 291 are arranged in a ring array relative to the central axis of the air diffuser head 29. This facilitates the air diffuser head 29 to rotate around the air intake pipe 24 when the exhaust gas blown into the air diffuser head 29 by the air intake pipe 24 is discharged through the air diffuser holes 291.

[0041] Furthermore:

[0042] In an optional embodiment, a through circular groove is formed on the surface of the actuating rod 210, and a fixed circular rod 218 is rotatably connected inside it. A torsion spring 219 is sleeved on the surface of the fixed circular rod 218. The two ends of the torsion spring 219 are fixedly connected to the fixed circular rod 218 and the actuating rod 210, respectively. A U-shaped seat 217 is provided on the surface of the fixed circular rod 218. The fixed circular rod 218 is fixedly connected inside the U-shaped seat 217. The U-shaped seat 217 is fixedly connected to the air diffuser head 29. A wedge block 220 is fixedly connected to the upper surface of the U-shaped seat 217.

[0043] In this implementation scheme: when the storage ring 23 is pushed out of the rubber sealing sleeve 22 and falls to the bottom of the liquid storage box 1, the storage ring 23 first lands on the upper surface of the actuating rod 210. Under the action of gravity, the actuating rod 210 rotates around the fixed round rod 218 until the storage ring 23 passes through the actuating rod 210. Under the action of the torsion spring 219, the actuating rod 210 returns to the state perpendicular to the center line of the air diffuser 29. The wedge block 220 fixed on the upper surface of the U-shaped seat 217 prevents the storage ring 23 from getting caught on the upper surface of the U-shaped seat 217. At the same time, it limits the actuating rod 210 so that the actuating rod 210 rotates to contact the wedge block 220 under the action of the elastic potential energy of the torsion spring 219 in its natural state. At this time, the actuating rod 210 can no longer rotate and keeps the upper surface of the actuating rod 210 perpendicular to the center axis of the air diffuser 29.

[0044] Furthermore:

[0045] In an optional embodiment, a limiting rod 221 is slidably connected in a through circular groove four on the upper surface of the liquid storage box 1. The limiting rod 221 is slidably connected in a through circular groove five on the surface of the rubber sealing sleeve 22, and the limiting rod 221 is fixedly connected to the storage ring 23 on the surface of the electric push rod 27.

[0046] In this implementation scheme: the limiting rod 221 ensures that the storage ring 23 remains stable when it moves downward inside the rubber sealing sleeve 22, preventing the storage ring 23 from tipping over in the direction of the electric push rod 27 during the downward movement.

[0047] Working principle: The exhaust gas purified by the three-way catalytic converter enters the intake manifold 24 through the exhaust pipe and then enters the reservoir 1. The carbon dioxide in the exhaust gas is absorbed by the sodium hydroxide solution inside the reservoir 1 and precipitates as carbon dioxide inside the reservoir 1. During the process of the exhaust gas flowing into the intake manifold 24 from the exhaust pipe, the concentration of carbon dioxide in the exhaust gas is detected by the concentration detector 25 installed on the intake manifold 24. The gas volume detector 26 calculates the volume of exhaust gas flowing into the intake manifold 24. After processing by the processor 28, when the sodium hydroxide solution inside the reservoir 1 is about to be exhausted, the electric push rod 27 pushes the storage ring 23 inside the rubber sealing sleeve 22 towards... The downward push causes the storage ring 23 at the bottom of the rubber sealing sleeve 22 to fall into the liquid storage box 1, thereby dissolving the sodium hydroxide solid inside the storage ring 23 into the water in the liquid storage box 1, thus maintaining the continuous adsorption of carbon dioxide by the device. The deformation direction of the rubber sealing sleeve 22 is restricted by the inner wall of the fixed pipe 21 and the surface of the air inlet pipe 24, making it difficult for the storage rings 23 inside the rubber sealing sleeve 22 to detach from the rubber sealing sleeve 22 under the action of gravity. When the exhaust gas is blown into the diffuser head 29 from the air inlet pipe 24, the diffuser head 29 rotates around the air inlet pipe 24 through the diffuser hole 291, thereby causing the actuating rod 210 to move with the rotation of the diffuser head 29. The actuating rod 210 moves to the position of the fixed bearing 211. When the driven rod 212 on the bottom surface contacts each other, it drives the driven rod 212 to rotate around the fixed tube 21. Through the cooperation of the driven rod 215 and the driven rod 216, it drives the scraper 214 on the fixed bearing 213 to rotate around the fixed tube 21. During this process, the scraper 214 continuously scrapes the bottom surface of the gas-liquid separation membrane 12 to prevent the bottom surface of the gas-liquid separation membrane 12 from being blocked by particulate carbon, precipitated sodium hydroxide, and precipitated sodium carbonate. When the storage ring 23 is pushed out of the rubber sealing sleeve 22 and falls to the bottom of the liquid storage box 1, the storage ring 23 first lands on the upper surface of the actuating rod 210. Under the action of gravity, the actuating rod 210 rotates around the fixed round rod 218 until the storage ring 23 passes through. The actuating lever 210 returns to a state perpendicular to the center line of the air diffuser 29 under the action of the torsion spring 219. The wedge block 220 fixed on the upper surface of the U-shaped seat 217 prevents the storage ring 23 from getting caught on the upper surface of the U-shaped seat 217, and also limits the actuating lever 210. Under the action of the elastic potential energy of the torsion spring 219, the actuating lever 210 rotates until it contacts the wedge block 220. At this time, the actuating lever 210 can no longer rotate, and the upper surface of the actuating lever 210 remains perpendicular to the center axis of the air diffuser 29. The limiting rod 221 keeps the storage ring 23 stable when it moves downward inside the rubber sealing sleeve 22, and prevents the storage ring 23 from tipping over in the direction of the electric push rod 27 during the downward movement.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
