[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, the spray pipe and the hot gas compensation pipe are provided with electromagnetic valves, and the outside of the fixed shell is provided with a controller relative to the electromagnetic valves.

[0007] As a further preferred, the jet seat is provided with a plurality of jet holes, and each of the jet holes sprays gas to one of the adsorption units in the heating zone B.

[0008] As a further preferred, the bottom of the cooling and discharging zone C is equipped with a collection cover, and the bottom of the collection cover is provided with a leakage hole.

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

[0011] As a further preferred, the adsorption zone A occupies an angle range of 270 degrees in the fixed shell, and the heating zone B and the cooling and discharging zone C occupy an angle range of 90 degrees in the fixed shell.

[0012] The beneficial effects of the present application compared with the prior art are:

[0013] A rotating shaft is arranged in the fixed shell, and a large number of fan-shaped adsorption units are arranged on the rotating shaft, and when CO2 in industrial waste gas is subjected to decarburization treatment, the rotating shaft drives all the adsorption units to rotate, and the centrifugal force generated by the rotation forces the gas to penetrate the adsorbent fiber bundle of the adsorption unit, so that the gas after decarburization is directly discharged outward through the purification cavity in the center of the rotating shaft, the discharge distance of the gas is shortened, the volume of the equipment is reduced, and the centrifugal decarburization mode enhances the strength, such as under the centrifugal force of the adsorption unit, the waste gas can be strongly “pulled into” the adsorbent fiber bundle for treatment, and then penetrate the air hole on the rotating shaft to enter the purification cavity and be concentrated and discharged upward, thereby improving the efficiency. The centrifugal force replaces most of the fan pressure drop energy consumption, so that the waste gas quickly penetrates the adsorbent fiber bundle in a high-pressure centrifugal force mode and quickly completes the decarburization treatment. The adsorbent fiber bundle has high mechanical strength, small wear and long mechanical life, and is arranged in the fixed shell with the adsorption unit, so that the high-temperature exposure time of the adsorbent is reduced, and the chemical service life is long. Moreover, the centrifugal force replaces most of the energy for pushing air through the adsorption bed, and the entire system has only one main moving part, and the structure is simple. Compared with the fixed bed system which needs a large number of valve switches, there are fewer potential failure points, and the maintenance cost is lower. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0023] The above and other embodiments and advantages of the present application will become more apparent from the following description in conjunction with the accompanying drawings. It is to be understood that the described embodiments are merely part of the present application, but not all of the present application.

[0024] In an embodiment, as shown in Figures 1-8

[0025] ​The application discloses an air carbon capture adsorption device, which comprises a fixed shell 1 and a rotating rotor assembly installed in the fixed shell 1, three partition plates 2 are arranged in the fixed shell 1, the inner cavity of the fixed shell 1 is divided into an adsorption area A, a heating area B and a cooling and discharging area C by the three partition plates 2, the rotor assembly comprises a rotating shaft 3 connected to the fixed shell 1 and a plurality of rotor discs 4 installed on the rotating shaft 3 in the axial direction, in fact, a motor is arranged at the bottom of the fixed shell 1, the rotating shaft 3 is driven to rotate by the motor, and all the rotor discs 4 are driven to rotate by the rotating shaft 3, each rotor disc 4 is divided into a plurality of adsorption units 5, the top end of the rotating shaft 3 is connected to the center top end of the partition plate 2, a slot 6 for enabling the adsorption units 5 to rotate through is formed in the partition plate 2, adsorbent fiber bundles 7 are filled in the adsorption units 5, a purification cavity 8 is formed in the rotating shaft 3, the top end of the purification cavity 8 penetrates the top end of the rotating shaft 3, a discharge pipe 9 in communication with the top end of the purification cavity 8 is installed at the center end of the partition plate 2, a spraying pipe entering the cooling and discharging area C is connected to the discharge pipe 9, a secondary heating device is connected to the pipeline of the discharge pipe 9, the gas outlet end of the secondary heating device is communicated with the heating area B, a capture cover 12 is arranged at the bottom of the cooling and discharging area C, and a leakage hole is formed in the bottom of the capture cover 12.

[0026] Industrial waste gas (industrial waste gas after heat exchange and cooling, generally about 40 DEG C, and the adsorbent fiber bundles 7 are relatively stable) enters the adsorption area A, the rotating shaft 3 is driven to rotate by the motor, all the rotor discs 4 drive all the adsorption units 5 to rotate, the adsorption units 5 generate centrifugal force, under the action of the centrifugal force, the waste gas is efficiently penetrated through the adsorbent fiber bundles 7, after purification treatment of the adsorbent fiber bundles 7, CO2 is captured on the purification agent, and the purified air enters the purification cavity 8 in the rotating shaft 3 through the air holes under the centrifugal action, with the continuous entry of the purified gas, the utilization of the centrifugal force strengthens the adsorption mass transfer and desorption mass transfer process, the rate is greatly improved, the treatment capacity of the unit volume adsorbent is improved, the centrifugal force replaces most of the energy used to push the air to pass through the adsorption bed, the whole system has only one main moving part (the rotating shaft 3), the structure is simple, compared with the fixed bed system which needs a plurality of valve switches, potential failure points are less, and the maintenance cost is lower.

[0027] It needs to be further explained in the embodiment that in the high-speed rotation of the rotating shaft 3, the waste gas is subjected to the action of the centrifugal force, as a result, the waste gas is first thrown to the cavity wall of the fixed shell 1 in a centrifugal manner from the center of the rotating shaft, with the continuous centrifugal force, the static pressure gradually increases when being thrown to the circumference, and the pressure at the shaft center is relatively low, thus a natural pressure gradient is formed, that is, the pressure at the outer ring is greater than the pressure at the shaft center, so that the waste gas is penetrated through the adsorbent fiber bundles 7 in a high-pressure manner for decarburization treatment, and then the purified gas is discharged in a high-pressure manner through the air holes on the rotating shaft 3 into the purification cavity 8.

[0028] It is further explained in this embodiment that the adsorbent fiber bundle 7 is essentially a flexible, high specific surface area composite material formed by combining high performance adsorbent with carrier fibers, which can be imagined as a "functional towel", and the adsorbent can be imagined as soap or detergent impregnated on the towel, which is responsible for capturing CO2 active ingredients. It is not a container filled with adsorbent particles, but the adsorbent itself is "grown" or "grafted" on the surface of each fiber to form a whole bundle structure with purification gaps or pores. The fiber bundle structure is loose, and air can easily penetrate, and the fan energy consumption is greatly reduced. The active site is directly exposed on the fiber surface, CO2 does not need to diffuse for a long distance, and is distributed in 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, and then penetrate the air hole on the rotating shaft 3 into the purification cavity 8 and concentrate upward for discharge, which improves the efficiency.

[0029] It is further explained in this embodiment that, as shown in Figure 6 , Figure 7 The rotating shaft 3 has a purification cavity 8 at the center, the top end of the rotating shaft 3 is connected to the collection position above the center of the three partition plates 2 through a bearing, the three partition plates 2 are fixed in the fixed shell 1, and the three partition plates 2 are stationary, so as to ensure the rotation of the rotating shaft 3. The bottom of the rotating shaft 3 is connected to the bottom surface of the fixed shell 1 through another bearing, and the bottom end of the rotating shaft 3 is connected to the third party motor through a transmission as shown in Figure 1 , so as to provide rotating power to the rotating shaft 3.

[0030] The adsorption area A occupies an angle range of 270 degrees in the fixed shell 1, and the heating area B and the cooling and discharging area C occupy a total angle range of 90 degrees in the fixed shell 1.

[0031] In this embodiment, the purified gas is discharged into the discharge pipe 9 through the purification channel 8, and is discharged 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 pipe inside. The gas outlet pipe on the secondary heating device is opened, so that the purified exhaust gas is heated to 80-100°C and discharged into the heating zone B. The temperature of the heating zone B is increased, and the adsorption unit 5 is rotated into the heating zone B. The heat is quickly transferred to the adsorption unit 5, so that the temperature of the amine adsorbent in the adsorbent fiber bundle 7 is increased, and the activity of the adsorbent is particularly enhanced. The adsorption unit 5 with the adsorbent fiber bundle 7 continues to rotate to the cooling discharge zone C. By using the rotational centrifugal force and the activity of the amine adsorbent caused by the heating of the adsorbent fiber bundle 7, CO2 is separated from the amine adsorbent and falls into the cooling discharge zone C to complete the desorption. Finally, the exhaust gas is discharged into the capture cover 12 through the exhaust holes at the bottom of the cooling discharge zone C to complete the capture. The cooling discharge zone C is provided with a spray pipe. After the spray pipe is opened, the gas in the discharge pipe 9 is intercepted and used in the cooling discharge zone C to quickly cool the cooling discharge zone C. When the adsorption unit 5 rotates to the cooling discharge zone C, it is cooled again to below 40°C, so that the adsorption unit 5 returns to normal. The adsorption unit 5 is rotated again to the adsorption zone A to perform the next cycle of adsorption treatment on the exhaust gas in the adsorption zone A.

[0032] In this embodiment, the gas in the heating zone B and the cooling discharge zone C comes from the purified gas in the adsorption zone A, so that the purified gas (regeneration hot gas flow) is reused, saving energy.

[0033] The spray pipe system is provided with a plurality of spray pipe units 10 extending into the cooling discharge zone C and atomizing nozzles 11 connected to each spray pipe 10. The plurality of spray pipes 10 form an arc and are distributed near the periphery of the adsorption unit 5, and the atomizing nozzles 11 face the adsorption unit 5. These atomizing nozzles 11 act on the adsorption unit 5 entering the cooling discharge zone C in the form of atomization, so that the adsorption unit 5 is uniformly cooled in the cooling discharge zone C. At the same time, it also ensures that the adsorption unit 5 is instantaneously transferred from the high-temperature heating zone B to the cooling discharge zone C, and CO2 is desorbed into the cooling discharge zone C, and finally collected into the capture cover 12.

[0034] The desorption principle is further explained as follows: the temperature of the adsorption zone A is low (about 40°C of the heat exchange exhaust gas). At low temperature, the chemical bond ("glue") between the active sites on the surface of the adsorbent and the CO2 molecules is very strong. At this time, the centrifugal force tries to blow the CO2 particles from the sponge. However, because the "glue" is too strong, the wind is not strong enough to overcome the strength of the chemical bond, and cannot make the CO2 fall off. Instead, this wind plays an active role, it forces the exhaust gas containing CO2 to penetrate the sponge at high speed, so that more CO2 particles have the opportunity to contact the glue and be stuck. At this time, the centrifugal force strengthens the "adsorption mass transfer" process, but it is not the cause of "desorption" itself. The heating zone B is equivalent to a high-temperature regeneration zone, and the heating zone B is provided with a lot of energy, which greatly weakens the chemical bond between the adsorbent and the CO2 molecules. It can be understood that high temperature makes the "glue" soften and lose adhesion. At the moment when the adsorption unit 5 is transferred from the heating zone B to the cooling and discharging zone C, the bond becomes very weak, and the CO2 particles are thrown into the cooling and discharging zone C under the action of centrifugal force to complete the desorption.

[0035] As Figure 2 , Figure 3 and Figure 5As shown, in another embodiment, the secondary heating device comprises a heating cabin 15 fixed on the outside of the exhaust pipe 9, a spray pipe system connected to the pipeline of the exhaust pipe 9, and a hot gas compensation pipe 16 connected to the gas outlet end of the heating cabin 15, the gas outlet end of the hot gas compensation pipe 16 enters the heating zone B and is connected with a gas injection seat 17, the gas injection seat 17 is provided with a plurality of injection holes 18, each of the injection holes 18 sprays gas into the heating zone B for one of the adsorption units 5. The exhaust pipe 9 discharges part of the purified gas in the purification channel 8 into the heating cabin 15 for secondary heating, and discharges another part of the gas into the spray pipe 10 of the spray pipe system. The total pipe on which the spray pipe 10 is located and the hot gas compensation pipe 16 are provided with electromagnetic valves 19, and the outside of the fixed shell 1 is provided with a controller relative to the electromagnetic valves 19. The controller controls the electromagnetic valves 19 on the total pipe on which the spray pipe 10 is located to be opened, so that the low-temperature gas after decarburization is taken from the exhaust pipe 9 to the spray pipe 10, or the electromagnetic valves 19 are closed, so that the low-temperature gas after decarburization is discharged into the heating cabin 15 in a single channel mode through the exhaust pipe 9, instead of entering the spray pipe system in the cooling discharge zone C; Similarly, the controller can also control the electromagnetic valves 19 on the hot gas compensation pipe 16 to be opened, so that the heated gas is discharged from the hot gas compensation pipe 16 into the heating zone B, or the electromagnetic valves 19 are closed, so that the hot gas compensation pipe 16 stops supplying gas to the heating zone B. For example, when the adsorption unit 5 needs to rotate 30 times in the fixed shell 1 before decarburization treatment, the controller module reaches the instruction of rotating the motor (the motor drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the adsorption unit 5 to rotate) for 30 times, and controls the two electromagnetic valves 19 to be opened at the same time. At this time, the hot gas compensation pipe 16 supplies hot gas to the heating zone B, the hot gas is sprayed into the heating zone B through the injection holes 18 on the gas injection seat 17, the temperature of the heating zone B is raised, the spray pipe 10 cuts off the low-temperature gas from the exhaust pipe 9 and blows it into the cooling discharge zone C, so that the temperature of the cooling discharge zone C is lowered, and when the adsorption unit 5 rotates to the heating zone B again, the adsorbent fiber bundle 7 is heated and activated. With the adsorption unit 5 rotating into the cooling discharge zone C for a moment, the desorption of CO2 and the cooling of the adsorbent fiber bundle 7 are completed. This control mode can be used for controllable decarburization treatment according to the concentration of CO2 molecules in the exhaust gas, and improves the practical value.

[0036] The adsorbent fiber bundle 7 is composed of a carrier fiber and an active amine adsorbent loaded on the surface of the carrier. The carrier fiber is one of glass fiber, ceramic fiber, cellulose fiber or polymer fiber, and has a bundle shape. For example, an impregnation method is used: the carrier fiber is immersed in an amine solution, and after being taken out and dried, the amine compound is physically attached to the surface and pores of the fiber; a chemical grafting method is used: through chemical reaction, the amine molecules are firmly "connected" to the surface of the fiber in the form of covalent bond, so as to improve the saturation degree. Finally, the obtained fiber cotton is filled into the adsorption unit 5.

[0037] 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.

[0038] 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.

[0039] 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.

This implementation scheme is only for the convenience of describing the scheme and to make relative descriptions based on the orientations of the references. In reality, the specific orientations of each component are based on their actual installation and use, as well as the orientation descriptions that are customary to those skilled in the art. This is hereby stated.
