Description

Technical Field

[0002] A carbon dioxide removal device is a device used to remove carbon dioxide (CO2) from gases or liquids. It separates CO2 from mixtures through physical, chemical, or biological methods to purify gases, control the environment, or recycle resources.

[0003] The prior art discloses a carbon dioxide removal device (CN216874813U). In order to solve the problem that the concentration measurement of traditional carbon dioxide removal devices is generally done manually, which is time-consuming and labor-intensive, a carbon dioxide removal device is provided. The device includes a removal chamber, with casters installed at the bottom of the removal chamber and a fan installed at the top of the removal chamber. The fan is connected to an air inlet pipe, and a first solenoid valve is installed on the air inlet pipe. A concentration sensor is installed on the left side of the first solenoid valve. A controller is installed on the outer wall of the removal chamber. A second activated carbon box is installed on the left side of the inside of the removal chamber, and a first activated carbon box is installed on the right side of the second activated carbon box.

[0004] Research revealed that existing technologies use direct electric heating to regenerate the adsorbent and activated carbon adsorption structures for removal. However, activated carbon has limitations in removing high concentrations of carbon dioxide, easily becoming saturated and resulting in incomplete removal. Furthermore, some gases contain water vapor, and the effective components in activated carbon are easily saturated with water vapor, leading to frequent shutdowns for replacement. This not only results in high maintenance costs but also seriously affects the operating efficiency of the device.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A carbon dioxide removal device, comprising The removal chamber has an adsorption cylinder fixedly installed on its top. A controller is installed on one side of the removal chamber. The removal chamber is equipped with an outlet valve, an exhaust valve, and a regeneration gas inlet valve. Two fans are symmetrically installed on the top surface of the removal chamber, and the regeneration gas inlet valve is connected to one of the fans. A dual-compartment adsorption assembly is movably disposed within a removal chamber. The dual-compartment adsorption assembly includes an adsorption chamber, a rack, and a gear. Two adsorption chambers and two racks are provided. The two racks are arranged symmetrically about the gear. Each of the two adsorption chambers is fixed to one rack. The adsorption chambers and racks are slidably disposed within the removal chamber. The gear is rotatably disposed within the removal chamber.

[0007] In a preferred embodiment of the present invention, an air inlet pipe and a liquid spray pipe are fixedly provided on the top of the adsorption cylinder. The air inlet pipe is connected to the adsorption cylinder. An exhaust pipe is fixedly provided between the adsorption cylinder and the removal chamber. The exhaust pipe is connected to the inside of the removal chamber through another fan.

[0008] In a preferred embodiment of the present invention, an air pump is fixedly provided on one side of the adsorption cylinder, and the air extraction pipe is connected to another fan through the air pump. Two electric heating wires are symmetrically installed on the top surface inside the removal box, and each of the two electric heating wires corresponds to one fan.

[0009] In a preferred embodiment of this utility model, a square moving groove is provided in the center of the internal part of the removal box. A limiting plate is symmetrically fixed on one side of the moving groove. A gear is rotatably arranged between the two limiting plates. A motor is fixed in the center of the outer wall of the removal box. The output end of the motor passes through the moving groove and is connected to one side of the gear.

[0010] In a preferred embodiment of this utility model, the two rack drives mesh with the same gear, the rack slides between the moving groove and the limiting plate, and the adsorption chamber slides between the inner wall of the removal box and the moving groove.

[0011] In a preferred embodiment of the present invention, one of the adsorption chambers is filled with a layered adsorbent, and two baffles are snapped onto the side of the removal chamber away from the motor, with the two baffles corresponding to the two adsorption chambers respectively.

[0013] Compared with the prior art, the present invention has the following advantages: 1.

At the same time, the other unsaturated adsorption chamber is moved to the adsorption chamber to continue working, realizing a continuous cycle of adsorption and regeneration, which greatly improves the working efficiency of the device and reduces downtime caused by waiting for adsorbent regeneration.

[0014] 2. The layered adsorbent and electric heating wire setup, compared to traditional single activated carbon adsorption, can more effectively handle complex gas environments containing high concentrations of carbon dioxide and water vapor. Different functional adsorption layers can adsorb carbon dioxide and water vapor separately, avoiding the problem of rapid adsorbent saturation due to water vapor, extending the adsorbent's lifespan, and reducing maintenance costs. Simultaneously, a specific liquid can be sprayed into the adsorption chamber through the liquid inlet spray pipe to pre-treat the incoming gas, further improving the adsorption effect of the subsequent adsorption chamber on carbon dioxide.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0019] A carbon dioxide removal device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including The removal chamber 10 has an adsorption cylinder 17 fixed on its top for preliminary treatment of the gas to be decarbonized. A controller 15 is installed on one side of the removal chamber 10. The removal chamber 10 is equipped with an outlet valve 11, an exhaust valve 12, and a regeneration gas inlet valve 13. The controller 15 is the core of the entire device and is connected to the outlet valve 11, the exhaust valve 12, the regeneration gas inlet valve 13, and the electric heating wire 23 via electrical signals to achieve precise control of each component. Two fans 16 are symmetrically installed on the top surface of the removal chamber 10. The regeneration gas inlet valve 13 is connected to one of the fans 16. There are two partitions fixed symmetrically inside the removal chamber 10, which divide the removal chamber 10 into a regeneration heating chamber and an adsorption chamber. The outlet valve 11 and the regeneration gas inlet valve 13 are both connected to the regeneration heating chamber, and the exhaust valve 12 is connected to the adsorption chamber, forming independent and mutually cooperating gas treatment spaces. The dual-compartment adsorption assembly is movably disposed within the removal chamber 10. The dual-compartment adsorption assembly includes adsorption chambers 27, racks 28, and gears 29. There are two adsorption chambers 27 and two racks 28. The two racks 28 are arranged symmetrically about the gear 29. Each adsorption chamber 27 is fixed to one rack 28. The adsorption chambers 27 and racks 28 are slidably disposed within the removal chamber 10. The gears 29 are rotatably disposed within the removal chamber 10.

[0020] Specifically, this device is equipped with a dual-chamber adsorption assembly. The meshing of the drive gear 29 with the two racks 28 drives the two corresponding adsorption chambers 27 to move relative to each other. This moves the saturated adsorption chamber 27 to the regeneration heating chamber for regeneration, while the other unsaturated adsorption chamber 27 is moved to the adsorption chamber to continue working. This achieves a continuous cycle of adsorption and regeneration, which greatly improves the working efficiency of the device and reduces downtime caused by waiting for adsorbent regeneration.

[0021] like Figure 1 and Figure 2 As shown, an air inlet pipe 19 and a liquid spray pipe 20 are fixedly provided on the top of the adsorption cylinder 17. The air inlet pipe 19 is connected to the adsorption cylinder 17. An exhaust pipe 18 is fixed between the adsorption cylinder 17 and the removal box 10. The exhaust pipe 18 is connected to the inside of the removal box 10 through another fan 16. like Figure 1 , Figure 2 and Figure 3 As shown, an air pump 21 is fixedly installed on one side of the adsorption cylinder 17. The air extraction pipe 18 is connected to another fan 16 through the air pump 21. Two electric heating wires 23 are symmetrically installed on the top surface inside the detachment box 10, and each of the two electric heating wires 23 corresponds to one fan 16. Figure 1 and Figure 2As shown, the controller 15 is electrically connected to the outlet valve 11, the exhaust valve 12, the regenerated gas inlet valve 13, and the electric heating wire 23. The working principle is as follows: High-concentration carbon dioxide is initially adsorbed and removed using the adsorption cylinder 17. Most of the carbon dioxide is absorbed by adding an amine solution to the inlet spray pipe 20. The remaining gas is then transported to the adsorption chamber via the extraction pipe 18, where it is further removed by the adsorption chamber 27. During this process, the extraction pipe 18, carrying water vapor, is agitated by the fan 16 and passed through the corresponding electric heating wire 23 for heating and dehydration. This avoids the problem of rapid saturation of activated carbon due to excessive moisture, extending the service life of the adsorbent, reducing maintenance costs, and further improving the adsorption effect of the subsequent adsorption chambers on carbon dioxide. Similarly, regeneration gas, such as nitrogen, is introduced through the inlet valve 13. The nitrogen passes through the fan 16 and the electric heating wire 23, carrying heat into the regeneration heating chamber to create a hot air environment, thereby regenerating the saturated adsorption chambers within the regeneration heating chamber. The device controls… The device 15 is additionally connected to a humidity sensor for detecting the humidity of the gas in the adsorption chamber and a temperature sensor for detecting the temperature in the regeneration heating chamber. The humidity sensor senses the humidity of the gas in the adsorption chamber and transmits the data to the controller 15. The controller 15 controls the temperature of the electric heating wire in the adsorption chamber. Similarly, the temperature sensor senses the temperature in the regeneration heating chamber to ensure the stable progress of the regeneration reaction, thereby controlling the heating temperature of the electric heating wire in the regeneration heating chamber. At the same time, each of the two adsorption chambers 27 is equipped with a pressure sensor for sensing the saturation of the adsorbent. Since the stratified adsorbents available on the market are a combination of large-pore molecular sieves and activated carbon, pore blockage will occur after adsorption saturation, increasing the resistance to gas passage and causing the pressure difference between the inlet and outlet to rise. Therefore, the pressure sensor can sense whether the adsorbent is saturated, so that the controller 15 can adjust the position of the adsorption chamber 27 according to the degree of saturation.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, a square moving groove 24 is provided in the center of the inside of the removal box 10. A limit plate 25 is symmetrically fixed on one side of the moving groove 24. A gear 29 is rotatably arranged between the two limit plates 25. A motor 26 is fixed in the center of the outer wall of the removal box 10. The output end of the motor 26 passes through the moving groove 24 and is connected to one side of the gear 29. like Figure 2 , Figure 3 and Figure 4 As shown, two racks 28 mesh with the same gear 29. The racks 28 slide between the moving groove 24 and the limiting plate 25. The adsorption chamber 27 slides between the inner wall of the removal box 10 and the moving groove 24. The side of the limiting plate 25 near the gear 29 is set as an arc surface. The limiting plate 25 is embedded in one side of the moving groove 24. like Figure 1, Figure 2 and Figure 5 As shown, one of the adsorption chambers 27 is filled with layered adsorbent. Two covers 14 are snapped onto the side of the removal chamber 10 away from the motor 26. The two covers 14 correspond to the two adsorption chambers 27 respectively. Two slots corresponding to the adsorption chambers 27 are opened on the side of the removal chamber 10 away from the motor 26. The covers 14 are snapped into the slots to facilitate the replacement and maintenance of the adsorbent in the adsorption chamber 27.

[0023] The specific implementation method is as follows: First, the gas containing carbon dioxide to be treated is transported to the adsorption cylinder 17 through the inlet pipe 19. Depending on the specific conditions of the gas, a suitable liquid can be sprayed into the adsorption cylinder 17 through the liquid inlet spray pipe 20 to pre-treat the gas. After pre-treatment, the gas is pumped into the adsorption chamber of the removal box 10 through the exhaust pipe 18 by the gas pump 21 and the corresponding fan 16. In the adsorption chamber, the gas comes into full contact with the layered adsorbent in one of the adsorption chambers 27. The adsorbent adsorbs the carbon dioxide. The gas after carbon dioxide removal is discharged from the device through the outlet valve 11. When the adsorbent in the adsorption chamber 27 reaches saturation, the controller 15 controls the motor 26 to start, and the motor 26 drives the gear 29 to rotate. The gear 29 engages with the racks 28 on both sides, moving the saturated adsorption chamber 27 to the regeneration heating chamber via the racks 28. Simultaneously, it moves another unsaturated adsorption chamber 27 to the adsorption chamber to continue carbon dioxide adsorption. Inside the regeneration heating chamber, the controller 15 controls the electric heating wire 23 to heat up, and the fan 16 sends hot air into the regeneration heating chamber to heat and regenerate the adsorbent in the saturated adsorption chamber 27, restoring its adsorption capacity. After regeneration, the adsorbent in the adsorption chamber 27 can be inspected or replaced by opening the cover 14 as needed for future use. The entire process is automated by the controller 15, making operation convenient and quick, and enabling efficient and stable removal of carbon dioxide.
