Description

TECHNICAL FIELD

[0001] The present application relates to the field of air carbon capture technology, in particular to an air carbon capture adsorption device. BACKGROUND

[0002] Direct air carbon capture technology is an important key technology to deal with environmental pollution, which is mainly applied in industrial waste gas treatment process, especially in the waste gas with high carbon content. For carbon molecule capture, the current mainstream technology mainly uses fixed bed or slowly rotating adsorption wheel structure. However, the existing technology has the following defects: after heat exchange, the temperature of industrial waste gas is low, and the activity of CO2 component is low, which leads to slow diffusion speed of CO2 in adsorbent particles and low decarburization efficiency. Moreover, the device is large in size and complex in operation. The granular adsorbent is easy to be pulverized in repeated pressure change and switching, and the service life is shortened. SUMMARY

[0003] In order to solve the above problems, the present application provides an air carbon capture adsorption device, which comprises a fixed shell and a rotating rotor assembly installed in the fixed shell. Three partition plates are arranged in the fixed shell, which divide the inner cavity of the fixed shell into an adsorption zone A, a heating zone B and a cooling and discharging zone C. The rotor assembly comprises a rotating shaft connected to the fixed shell and a plurality of rotor discs installed on the rotating shaft along the axial direction. Each rotor disc is divided into a plurality of adsorption units. The top end of the rotating shaft is connected to the center top end of the partition plate. A slot is formed in the partition plate to allow the adsorption units to rotate through. The adsorption units are filled with adsorbent fiber bundles. A purification cavity is formed in the rotating shaft, and the top end of the purification cavity penetrates the top end of the rotating shaft. A discharge pipe is installed on the center end of the partition plate and communicates with the top end of the purification cavity. A spray pipe is connected to the discharge pipe and enters the cooling and discharging zone C. A secondary heating device is connected to the pipeline of the discharge pipe. The gas outlet of the secondary heating device communicates with the heating zone B.

[0004] As a further preferred, a plurality of shower pipe units are arranged in the cooling and discharging zone C, and an atomizing nozzle is connected to each shower pipe. The plurality of shower pipes form an arc shape and are distributed near the periphery of the adsorption units. The atomizing nozzles face the adsorption units.

[0005] As a further preferred, the secondary heating device comprises a heating cabin fixed to the outside of the discharge pipe. The spray pipe is connected to the pipeline of the discharge pipe. The secondary heating device further comprises a hot gas compensation pipe connected to the gas outlet of the heating cabin. The gas outlet of the hot gas compensation pipe enters the heating zone B and is connected to a gas injection seat.

[0006] As a further preferred embodiment, the spray pipe and the hot gas compensation pipe are equipped with solenoid valves, and the outside of the fixed housing is provided with a controller relative to the solenoid valves.

[0007] As a further preferred embodiment, the jet seat is provided with a plurality of jet holes, each of which sprays air into one of the adsorption units within the heating zone B.

[0008] As a further preferred embodiment, the bottom of the cooling and emission zone C is equipped with a trapping hood, and the bottom of the trapping hood has a leak.

[0009] As a further preferred embodiment, the adsorbent fiber bundle is composed of carrier fibers and an active amine adsorbent loaded on the surface of the carrier. The carrier fibers are one of glass fibers, ceramic fibers, cellulose fibers or polymer fibers, and are in the form of bundles.

[0010] As a further preferred embodiment, the fixed outer shell is provided with an exhaust gas inlet corresponding to the adsorption zone A; the inner side of the exhaust gas inlet is integrated with multiple nozzles, each nozzle spraying gas for one of the adsorption units.

[0011] As a further preferred embodiment, the adsorption zone A occupies an angle range of 270 degrees within the fixed outer shell, and the heating zone B and the cooling and emission zone C together occupy an angle range of 90 degrees within the fixed outer shell. The advantages of this invention compared to the prior art are: A rotating shaft is installed inside a fixed housing, and a large number of fan-shaped adsorption units are mounted on the shaft. When decarbonizing CO2 in industrial waste gas, the shaft drives all the adsorption units to rotate. The centrifugal force generated by the rotation forces the gas to penetrate the adsorbent fiber bundles within the adsorption units. The decarbonized gas is then directly discharged through the purification chamber at the center of the shaft, shortening the emission distance and reducing the equipment size. The centrifugal decarbonization mode enhances the decarbonization effect. Under the centrifugal force of the adsorption units, the waste gas is strongly "pulled" into the adsorbent fiber bundles for treatment before penetrating through the pores on the shaft and entering the purification chamber for concentrated upward discharge, improving efficiency. Centrifugal force replaces most of the energy consumption from the fan pressure drop, allowing the waste gas to quickly penetrate the adsorbent fiber bundles under high pressure and centrifugal force, rapidly completing the decarbonization process. The adsorbent fiber bundles have high mechanical strength, low wear, and long mechanical life. Furthermore, being installed inside the fixed housing with the adsorption units reduces the high-temperature exposure time of the adsorbent, resulting in a long chemical lifespan. Moreover, centrifugal force replaces most of the energy used to propel air through the adsorption bed. The entire system has only one main moving part, making it simple in structure. Compared to fixed-bed systems that require switching numerous valves, it has fewer potential points of failure and lower maintenance costs. Attached Figure Description

[0014] The above and other embodiments and advantages 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.

[0015] In one implementation, such as Figures 1-8 As shown: This invention discloses an air carbon capture and adsorption device, comprising a fixed outer shell 1 and a rotor assembly rotatably mounted within the fixed outer shell 1. The fixed outer shell 1 is provided with three partition plates 2, which divide the inner cavity of the fixed outer shell 1 into an adsorption zone A, a heating zone B, and a cooling and emission zone C. The rotor assembly includes a rotating shaft 3 connected to the fixed outer shell 1 and multiple rotor disks 4 mounted along the axial direction on the rotating shaft 3. In practice, a motor is located at the bottom of the fixed outer shell 1, driving the rotating shaft 3 to rotate, which in turn drives all the rotor disks 4 to rotate. Each rotor disk 4 is divided into several adsorption units 5. The top is connected to the center top of the partition plate 2. The partition plate 2 has a slot 6 for the adsorption unit 5 to rotate through. The adsorption unit 5 is filled with adsorbent fiber bundles 7. The rotating shaft 3 has a purification channel 8. The top of the purification channel 8 passes through the top of the rotating shaft 3. The center end of the partition plate 2 is equipped with a discharge pipe 9 that communicates with the top of the purification channel 8. The discharge pipe 9 is connected to a spray pipe that enters the cooling discharge zone C. The discharge pipe 9 is connected to a secondary heating device. The outlet of the secondary heating device is connected to the heating zone B. The bottom of the cooling discharge zone C is equipped with a trap hood 12. The bottom of the trap hood 12 has a leak.

[0016] Industrial waste gas (cooled industrial waste gas after heat exchange, generally around 40℃, where the adsorbent fiber bundle 7 is relatively stable) enters the adsorption zone A. The motor drives the rotating shaft 3 to rotate, causing all the rotor disks 4 to drive all the adsorption units 5 to rotate. The adsorption units 5 generate centrifugal force, and under the action of centrifugal force, the waste gas is efficiently penetrated by the adsorbent fiber bundle 7. After being purified by the adsorbent fiber bundle 7, CO2 is captured on the purifier. The purified air passes through the air holes and enters the purification chamber 8 of the rotating shaft 3 under centrifugal force. As the purified gas continues to enter, the use of centrifugal force enhances the adsorption and desorption mass transfer processes, greatly increasing the rate and improving the treatment capacity per unit volume of adsorbent. Centrifugal force replaces most of the energy used to propel the air through the adsorption bed. The entire system has only one main moving part (rotating shaft 3), with a simple structure. Compared with fixed bed systems that require switching numerous valves, it has fewer potential failure points and lower maintenance costs.

[0017] In this embodiment, it should be further explained that during the high-speed rotation of the rotating shaft 3, the exhaust gas is subjected to centrifugal force. As a result, the exhaust gas is first thrown from the center of the rotating shaft to the cavity wall of the fixed outer shell 1 in a centrifugal manner. As the centrifugal force continues, the static pressure thrown towards the circumference gradually increases, while the pressure at the axial center is lower. This forms a natural pressure gradient, that is, the pressure in the outer ring is greater than the pressure at the axial center. This forces the exhaust gas to penetrate the adsorbent fiber bundle 7 under high pressure and be decarbonized. Then, the purified gas passes through the air holes on the rotating shaft 3 under centripetal pressure and enters the purification cavity 8 for discharge.

[0018] In this embodiment, it should be further explained that the adsorbent fiber bundle 7 is essentially a flexible composite material with a high specific surface area, formed by combining a high-performance adsorbent with a carrier fiber. It can be imagined as a "functional towel," with the adsorbent like soap or detergent soaked in it, responsible for capturing the active components of CO2. It is not a container filled with adsorbent particles, but rather the adsorbent itself is "grown" or "grafted" onto the surface of each fiber, forming a holistic bundle structure with purification gaps or pores. The loose fiber bundle structure allows air to easily penetrate, significantly reducing fan energy consumption. The active sites are directly exposed on the fiber surface, eliminating the need for long-distance CO2 diffusion. Furthermore, the fiber bundle is distributed within each adsorption unit 5, and under the centrifugal force of the adsorption unit 5, the exhaust gas can be strongly "pulled" into the adsorbent fiber bundle 7 for treatment before penetrating the pores on the rotating shaft 3 and entering the purification chamber 8 for concentrated upward emission, thus improving efficiency.

[0019] It should be further explained in this embodiment that, for example Figure 6 , Figure 7 As shown, a purification chamber 8 is opened at the axis of the rotating shaft 3. The top end of the rotating shaft 3 is connected to the convergence position of three partition plates 2 above the axis via a bearing. The three partition plates 2 are fixed inside the fixed housing 1 and do not move, thus ensuring the rotation of the rotating shaft 3. The bottom end of the rotating shaft 3 is connected to the bottom surface of the fixed housing 1 via another bearing, and the bottom end of the rotating shaft 3 is connected to the bottom outside of the fixed housing 1. Figure 1 The transmission shown is on a third-party motor, which provides rotational power to the rotating shaft 3.

[0020] The adsorption zone A occupies an angle range of 270 degrees within the fixed outer shell 1, while the heating zone B and the cooling and emission zone C occupy a combined angle range of 90 degrees within the fixed outer shell 1.

[0021] In this embodiment, the purified gas is discharged into the discharge pipe 9 through the purification chamber 8, and then into the secondary heating device through the other end of the discharge pipe 9. The secondary heating device can be understood as a heater with a heating tube inside. The gas outlet pipe on the secondary heating device is opened to heat the purified waste gas to 80~100°C and discharge it into the heating zone B. The temperature of the heating zone B rises, and the adsorption unit 5 rotates into the heating zone B. The heat is quickly transferred to the adsorption unit 5, which raises the temperature of the amine adsorbent in the adsorbent fiber bundle 7, especially enhancing the activity of the adsorbent. The adsorption unit 5 continues to rotate with the adsorbent fiber bundle 7 to the cooling discharge zone C. Using the centrifugal force of rotation and the activity of the amine adsorbent caused by the heating of the adsorbent fiber bundle 7, CO2 is desorbed from the amine adsorbent and falls into the cooling discharge zone C to complete the desorption. Finally, it is discharged into the collection hood 12 through the discharge hole at the bottom of the cooling discharge zone C to complete the collection. A spray pipe is installed in the cooling emission zone C. After the spray pipe is opened, the gas in the emission pipe 9 is intercepted and used in the cooling emission zone C to quickly cool down the cooling emission zone C. When the adsorption unit 5 rotates to the cooling emission zone C, it is cooled down to below 40°C again, so that the adsorption unit 5 returns to normal. The adsorption unit 5 then rotates to the adsorption zone A again to perform the next cycle of adsorption treatment on the waste gas in the adsorption zone A.

[0022] In this embodiment, the gases in heating zone B and cooling emission zone C both come from the gas purified in adsorption zone A, so that the purified gas (regenerated hot gas flow) is reused, saving energy.

[0023] The spray pipe system is equipped with several spray pipe units 10 extending into the cooling and emission zone C and atomizing nozzles 11 connected to each spray pipe 10. The spray pipes 10 form an arc shape and are distributed near the periphery of the adsorption unit 5, with the atomizing nozzles 11 facing the adsorption unit 5. These atomizing nozzles 11 apply the purified gas in an atomized form to the adsorption unit 5 entering the cooling and emission zone C, ensuring uniform cooling of the adsorption unit 5 within the cooling and emission zone C. Simultaneously, it ensures that the adsorption unit 5 desorbs CO2 into the cooling and emission zone C the instant it turns from the high-temperature heating zone B, and finally collects it inside the collection hood 12.

[0024] The desorption principle is further explained below: The temperature in adsorption zone A is low (around 40°C for the heat exchange exhaust gas). At this low temperature, the chemical bonds ("glue") between the active sites on the adsorbent surface and the CO2 molecules are very strong. Centrifugal force attempts to blow the CO2 particles off the sponge. However, because the "glue" is too strong, the force of the wind is insufficient to overcome the strength of the chemical bonds, and the CO2 cannot be detached. Instead, this wind plays a positive role, forcibly propelling the CO2-containing exhaust gas through the sponge at high speed, allowing more CO2 particles to come into contact with the glue and be stuck. At this point, centrifugal force enhances the "adsorption-mass transfer" process, but it is not the cause of "desorption" itself. Heating zone B is equivalent to a high-temperature regeneration zone. The energy supplied to heating zone B greatly weakens the chemical bond forces between the adsorbent and the CO2 molecules. This can be understood as the high temperature softening the "glue" and causing it to lose its stickiness. At this moment, as the adsorption unit 5 transitions from the heating zone B to the cooling emission zone C, the bonding force becomes very weak, and under the action of centrifugal force, the CO2 particles are thrown into the cooling emission zone C to complete desorption.

[0025] like Figure 2 , Figure 3 as well as Figure 5As shown, in another embodiment, the secondary heating device includes a heating chamber 15 fixed to the outside of the discharge pipe 9, a spray pipe system connected to the discharge pipe 9, and a hot gas compensation pipe 16 connected to the outlet end of the heating chamber 15. The outlet end of the hot gas compensation pipe 16 enters the heating zone B and is connected to a jet seat 17. The jet seat 17 is provided with multiple spray holes 18, each of which sprays gas at one of the adsorption units 5 in the heating zone B. The discharge pipe 9 discharges a portion of the purified gas discharged from the purification chamber 8 into the heating chamber 15 for secondary heating, and discharges the other portion of the discharged gas onto the spray pipe 10 of the spray pipe system. Solenoid valves 19 are provided on the main pipe where the spray pipe 10 is located and on the hot gas compensation pipe 16. A controller is provided on the outside of the fixed housing 1 relative to the solenoid valve 19. The controller opens the solenoid valve 19 on the main pipe where the shower pipe 10 is located, so that the decarbonized low-temperature gas is carried from the discharge pipe 9 into the shower pipe 10, or closes the solenoid valve 19, so that the decarbonized low-temperature gas is discharged into the heating chamber 15 through the discharge pipe 9 in a single channel, instead of entering the spray pipe system in the cooling discharge zone C. Similarly, the controller can also open the solenoid valve 19 on the hot gas compensation pipe 16, so that the heated gas is discharged from the hot gas compensation pipe 16 into the heating zone B, or close the solenoid valve 19, so that the hot gas compensation pipe 16 stops supplying gas to the heating zone B. For example, when adsorption unit 5 needs to rotate 30 times within the fixed housing 1 before decarbonization, the controller module, upon receiving the instruction that the motor (which drives the rotating shaft 3 to rotate, which in turn drives the adsorption unit 5 to rotate) 30 times, controls the two solenoid valves 19 to open simultaneously. At this time, the hot gas compensation pipe 16 supplies hot gas to the heating zone B. The hot gas is injected into the heating zone B through the nozzle 18 on the jet seat 17, raising the temperature of the heating zone B. The spray pipe 10 intercepts low-temperature gas from the discharge pipe 9 and blows it into the cooling discharge zone C, lowering the temperature of the cooling discharge zone C. When adsorption unit 5 rotates back to the heating zone B, the adsorbent fiber bundle 7 is heated actively. As adsorption unit 5 instantly rotates into the cooling discharge zone C, CO2 desorption and cooling of the adsorbent fiber bundle 7 are completed. This control mode allows for controllable decarbonization based on the concentration of CO2 molecules in the waste gas, improving its practical value.

[0026] The adsorbent fiber bundle 7 consists of carrier fibers and an active amine adsorbent loaded on the surface of the carrier. The carrier fibers can be one of glass fibers, ceramic fibers, cellulose fibers, or polymer fibers, and are in bundle form. For example, an impregnation method can be used: the carrier fibers are immersed in an amine solution, and after drying, the amine compounds will physically adhere to the fiber surface and pores; a chemical grafting method can be used: through a chemical reaction, amine molecules are firmly "connected" to the fiber surface in the form of covalent bonds, increasing the saturation. Finally, the resulting fiber filaments are filled into the adsorption unit 5.

[0027] The fixed outer shell 1 is provided with an exhaust gas inlet 13 corresponding to the adsorption zone A; multiple nozzles 14 are integrated inside the exhaust gas inlet 13, and each nozzle 14 sprays gas for an adsorption unit 5, which increases the centrifugal force intensity and also increases the area of ​​action of exhaust gas on the adsorption unit 5, thereby improving the CO2 molecule capture efficiency.

[0028] In this embodiment, when the exhaust gas is heated to 80~100℃ and discharged into the heating zone B, it only serves to "bathe" the heating zone B. This gas can be understood as a "blowing fan," only "baking" the adsorbent fiber bundle 7 that enters the heating zone B with thermal energy, making the adsorbent attachment layer on the adsorbent fiber bundle 7 active. Moreover, the scope of the heating zone B is much smaller than that of the adsorption zone A. Therefore, the centrifugal force of the adsorption unit 5 carrying the adsorbent fiber bundle 7 into the heating zone B is insufficient to allow the gas to enter the purification chamber 8. Similarly, the gas entering the cooling emission zone C, after being atomized, only serves to cool the gas. The small rotation angle is also insufficient to allow the gas to enter the purification chamber 8 in the cooling emission zone C. Even if a small amount of gas enters, it will not affect the normal implementation of the decarbonization scheme.

[0029] In this practical application, an exhaust pipe is also required on the heating chamber 15. A one-way gas valve is installed on the exhaust pipe. When the amount of gas collected in the heating chamber 15 is large (for example, when the solenoid valve 19 on the hot gas compensation pipe 16 does not need to be opened, but the amount of gas collected in the heating chamber 15 gradually increases), the exhaust pipe will discharge the hot gas into the heating environment for reasonable use, so as to avoid the heating chamber 15 from exploding.
