Description

Technical Field

[0001] The present invention relates to the field of carbon dioxide processing, and in particular to a carbon dioxide capture device. Background Art

[0002] As is known to all, carbon capture refers to the process of removing carbon dioxide contained in flue gas. This technology is regarded as one of the important ways to address climate change and reduce greenhouse gas emissions. Carbon capture can be achieved through chemical, physical and biological methods. The captured carbon dioxide can be used for carbon sequestration, production of recycling products or further converted into other valuable substances. Organic amines are usually used as absorption liquid to absorb carbon dioxide in flue gas, and this process is usually carried out in an absorption tower.

[0003] For example, the Chinese patent document with publication number CN116510469A, publication date 2023-08-01, and titled "Carbon Dioxide Capture Tower" includes a pre-washing and impurity removal section, a carbon dioxide absorption section, and a flue gas washing section arranged in sequence from bottom to top in the vertical direction, so that the flue gas can flow through the pre-washing and impurity removal section, the carbon dioxide absorption section, and the flue gas washing section in sequence, and a carbon dioxide capture tower flue gas inlet is provided on the pre-washing and impurity removal section, and a carbon dioxide capture tower flue gas outlet is provided on the washing section. The purpose of this application is to provide a carbon dioxide capture tower to address the technical problems of high manufacturing cost of flue gas carbon dioxide capture system and large workload of later operation, overhaul and maintenance.

[0004] The shortcomings of the above-mentioned prior art are that, in the process of capturing carbon dioxide, after the absorption liquid falls from the packing mechanism, part of the flue gas containing carbon dioxide will come into contact with the saturated absorption liquid and be brought into the rich liquid by the saturated absorption liquid. The problem caused by this is that, on the one hand, the falling of the absorption liquid will increase the resistance of the flue gas to rise, and on the other hand, it will cause more bubbles to be contained in the rich liquid. Summary of the invention

[0005] The object of the present invention is to provide a carbon dioxide capture device to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] In the description of the present invention, it is to be understood that Figure 2The position of the middle exhaust pipe 5 relative to the liquid outlet pipe 7 is above, and vice versa. The terms "center", "lateral", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0030] Reference Figure 1-7 A carbon dioxide capture device provided by an embodiment of the present invention includes a shell 1 and an absorption chamber 2 constructed inside the shell 1, wherein a packing mechanism is rotatably arranged inside the shell 1; the shell 1 also includes an air inlet pipe 3, the outlet of the air inlet pipe 3 is close to the lower surface of the packing mechanism, and the outlet of the air inlet pipe 3 is coaxially arranged with the packing mechanism; and also includes a power component for driving the packing mechanism to rotate.

[0031] Specifically, the shell 1 is an ellipsoidal structure with a hollow interior, and the absorption chamber 2 is a hollow area inside the shell 1. The shell 1 is connected with an absorption liquid addition pipe 4, an exhaust pipe 5, an air inlet pipe 3 and a liquid outlet pipe 7. The packing mechanism is used to provide a space for the absorption liquid to contact with the flue gas. When carbon dioxide is captured, the flue gas containing carbon dioxide is added to the shell 1 through the air inlet pipe 3, and at the same time, the absorption liquid is added to the shell 1 through the addition pipe 4. The vertical height of the packing mechanism is between the addition pipe 4 and the air inlet pipe 3. The flue gas and the absorption liquid react inside the packing mechanism, so that carbon dioxide can be captured. The formed rich liquid containing carbon dioxide falls to the inner bottom wall of the shell 1 and is discharged through the liquid outlet pipe 7, and the captured gas is discharged through the exhaust pipe 5, so that the capture of carbon dioxide is achieved. This is a prior art and will not be repeated. One of the core innovations of the embodiment of the present invention is that the packing mechanism is rotatably arranged in the shell 1, and the outlet of the air intake pipe 3 is coaxially arranged below the packing mechanism, that is, the part of the air intake pipe 3 located inside the shell 1 is L-shaped, and its outlet extends to the bottom of the packing mechanism. The power component can be a structure in which the motor is directly connected to the packing mechanism, so that the packing mechanism can rotate inside the shell 1, such as The function of this arrangement is that when carbon dioxide is captured, the power assembly is started, and the power assembly drives the packing mechanism to rotate, so that the absorption liquid entering the packing mechanism moves downward and away from the central axis of the packing mechanism under the action of centrifugal force, so that most of the absorption liquid falls from a position close to the inner wall of the shell 1, and because the outlet of the air inlet pipe 3 is coaxially arranged below the packing mechanism, the saturated absorption liquid can be avoided from contacting with the uncaptured flue gas as much as possible. The advantages of such an arrangement are, firstly, it can reduce the resistance of the flue gas when it rises, and secondly, it can reduce the bubbles in the rich liquid (the flue gas The smoke is evenly introduced into the packing mechanism through a gas distributor. In the present application, the smoke is added from the center of the packing mechanism. After the smoke enters the packing mechanism, the absorption liquid is dispersed in a direction away from the center axis of the packing mechanism under the action of centrifugal force. When the smoke contacts the dispersed absorption liquid, it will simultaneously disperse in a direction away from the center axis of the packing mechanism. That is, a gas distributor is not designed in the present application, but the effect of the gas distributor is also achieved.

[0032] Preferably, the packing mechanism comprises a packing frame 8 and a filler 9 arranged inside the packing frame 8 , an annular groove 10 is formed on the inner wall of the housing 1 , and the packing frame 8 is dynamically sealedly connected to the annular groove 10 . Specifically, the packing rack 8 includes a cylindrical side wall, and its two open ends are provided with a well-shaped or cross-shaped retaining rack, and a metal wire mesh can be provided on the retaining rack to prevent the filler 9 from falling from the packing rack 8. The filler 9 is preferably a ball ring filler (the ball ring provides a large surface area so that the liquid and the gas can be in better contact, which helps to effectively improve the mass transfer and reaction efficiency, and because the design of the ball ring can reduce the resistance of the gas-liquid fluid, it can reduce the pressure drop of the packing layer and save energy. This is a prior art and will not be repeated). The annular groove 10 is opened on the inner wall of the shell 1, and its vertical height is located between the addition pipe 4 and the intake pipe 3. The cylindrical part of the packing rack 8 is dynamically sealed with the annular groove 10. The purpose of such a setting is that the packing rack 8 can rotate inside the annular groove 10, and because the cylindrical part of the packing rack 8 is dynamically sealed with the annular groove 10, it can be avoided as much as possible that the absorption liquid and gas enter between the packing rack 8 and the annular groove 10, so as to improve the capture quality of carbon dioxide.

[0033] Preferably, the filler 9 is made of plastic material, which makes the filler 9 have a smaller mass as a whole and has good corrosion resistance.

[0034] It should be noted that the motor is directly connected to the packing mechanism, and the leaked absorption liquid will reduce the service life of the motor. As an alternative solution to directly connecting the motor to the packing mechanism to drive the packing mechanism to rotate, the power assembly includes a drive motor 11 and a gear 12 connected to the output end of the drive motor 11, the drive motor 11 is fixed to the housing 1, and a gear ring 13 is provided on the packing frame 8, and the gear ring 13 is meshed with the gear 12. Specifically, the drive motor 11 is fixedly connected to the outer circumferential surface of the shell 1, the gear 12 is fixedly connected to the output end of the drive motor 11, the gear ring 13 is arranged on the outer circumferential surface of the filling frame 8, and the inner wall of the annular groove 10 is provided with a through hole for the teeth on the gear 12 to pass through, the gear 12 passes through the through hole and meshes with the gear ring 13, and a protective cover is provided on the shell 1, and the gear 12 is arranged inside the protective cover. The purpose of such a setting is that when carbon dioxide capture is carried out, the drive motor 11 is started, and the drive motor 11 drives the gear 12 at its output end to rotate. Since the gear 12 is meshed with the gear ring 13, the gear ring 13 and the filling frame 8 are driven to rotate synchronously to provide power for the filling frame 8 to rotate, and since the filling frame 8 is dynamically sealed with the annular groove 10, it can be avoided as much as possible that flue gas and absorption liquid enter the inside of the drive motor 11 through the through hole, thereby improving the service life of the drive motor 11.

[0035] As another embodiment of the present invention, the filling mechanism further comprises a placing rack 14 , the inner wall of the filling rack 8 is further provided with a slide groove 15 , the placing rack 14 is provided with a sliding connection portion 16 , and the sliding connection portion 16 is slidably connected to the slide groove 15 . Specifically, the placement rack 14 is preferably in a barrel shape, and its bottom is also provided with a retaining frame and a metal wire mesh and other structures for preventing the filler 9 from falling. The retaining frame and the metal wire mesh arranged at the bottom of the placement rack 14 replace the retaining frame and the metal wire mesh at the bottom of the filling rack 8, that is, in the present embodiment, the bottom end of the filling rack 8 is open, and the slide groove 15 is arranged along the inner circumference of the filling rack 8, and the slide groove 15 is preferably wavy, that is, the slide groove 15 includes multiple inclined sections, multiple highest points and multiple lowest points, and the sliding connection 16 is preferably in a round rod shape, and its end is preferably arc-shaped, and the radial dimension of the sliding connection 16 is adapted to the width of the slide groove 15. The sliding connection 16 should be no less than one and preferably two. The effect of such a setting is that, under the action of the gravity of the placement rack 14 and the filler 9, the placement rack 14 is in the lowest position, and at this time the sliding connection 16 is located at the lowest point of the slide groove 15. When the driving motor 11 drives When the dynamic filling rack 8 rotates, and when the gravity of the placement rack 14 and the filler 9 is greater than the force required for the relative rotation of the filling rack 8 and the placement rack 14, the rotation of the filling rack 8 will drive the placement rack 14 inside it to rotate synchronously, so as to drive the filler 9 inside it to rotate synchronously, so as to achieve the above-mentioned purpose of dispersing the absorption liquid and flue gas. When the carbon dioxide is captured, the drive motor 11 is controlled to stop, so that the gear 12, the gear ring 13 and the filling rack 8 stop synchronously. The placement rack 14 will continue to rotate for a period of time under the action of inertia, so that the placement rack 14 and the filling rack 8 rotate relative to each other, so that the sliding part 16 and the slide groove 15 slide relative to each other. Since the slide groove 15 is wavy, it can drive the placement rack 14 and the filler 9 inside it to shake up and down, so as to passively shake off the absorption liquid (or rich liquid) in the filling mechanism, so as to avoid the absorption liquid (or rich liquid) from remaining inside the filling mechanism as much as possible.

[0036] Furthermore, a pressure plate 17 is slidably provided on the filling frame 8 , and a first spring 18 is provided between the pressure plate 17 and the filling frame 8 . Specifically, an annular lifting groove 19 is provided on the inner wall of the filling rack 8 near the top, and the pressure plate 17 is of a tic-tac-toe or criss-cross structure, which is used to replace the baffle frame on the top of the filling rack 8, that is, in this embodiment, the filling rack 8 is only cylindrical, and a plurality of first springs 18 are provided. The plurality of first springs 18 are evenly arranged between the edge position of the upper surface of the pressure plate 17 and the inner top wall of the lifting groove 19, and the first springs 18 are in a compressed state. The advantages of such a setting are that, firstly, the pressure plate 17 can limit the position of the filler 9, so that the fillers 9 are almost in a relatively static state to prevent the fillers 9 from colliding with each other, thereby reducing damage to the fillers 9; secondly, the first spring 18 provides a downward force for the pressure plate 17. Since the pressure plate 17 abuts against the top of the placement rack 14, it can provide a downward force to the placement rack 14, so that the placement rack 14 is at the bottom, so that when the filling rack 8 rotates, the placement rack 14 can be stably driven to rotate.

[0037] Furthermore, an elastic sheet 20 is provided on the placement rack 14, and the elastic sheet 20 abuts against the filling rack 8. Specifically, the elastic sheet 20 is preferably arc-shaped and is preferably made of metal material, and a material with a large dynamic friction coefficient such as a rubber coating can be provided on the surface close to the filling rack 8. A plurality of mounting grooves 21 are provided on the outer peripheral surface of the placement rack 14, and the elastic sheet 20 is arranged in the mounting groove 21, and the elastic sheet 20 is in a stressed state. The arc surface of the elastic sheet 20 abuts against the inner wall of the filling rack 8, so that under the action of friction, when the filling rack 8 rotates, it can further stably drive the placement rack 14 to rotate.

[0038] Furthermore, a plurality of protrusions 22 are provided inside the slide groove 15, and a plurality of the protrusions 22 are located on the movement stroke of the sliding part 16. Specifically, the cross section of the protrusion 22 is arc-shaped, and the plurality of protrusions 22 are evenly arranged inside the slide groove 15, and there are no two protrusions 22 that are symmetrical about the center of the packing mechanism among the plurality of protrusions 22, that is, when one of the sliding parts 16 abuts against the protrusion 22, the other sliding part 16 will not abut against the protrusion 22, so as to avoid the jamming caused by the two sliding parts 16 abutting against the two protrusions 22 at the same time, and when the placement rack 14 is at the lowest end, the sliding part 16 abuts against one of the protrusions 22, so as to avoid the horizontal shaking of the placement rack 14 during capture as much as possible, and an annular gap 33 is provided between the placement rack 14 and the packing rack 8, and a flange 32 is provided at the bottom of the packing rack 8, so as to prevent the placement rack 14 from shaking horizontally ... The function of the device is that when the filling rack 8 drives the placement rack 14 to rotate synchronously, under the action of the elastic force of the first spring 18, the edge position of the pressure plate 17 seals the top of the annular gap 33, and the flange 32 at the bottom of the filling rack 8 can seal the bottom of the annular gap 33, so that the absorption liquid and smoke can be prevented from entering the annular gap 33 as much as possible. When the filling rack 8 stops, the placement rack 14 rotates relative to the filling rack 8, so that the sliding part 16 slides in the slide groove 15, and in the sliding process, the arc surface of the sliding part 16 abuts against the arc surface of the protrusion 22, so that the filling rack 8 can be passively shaken in the horizontal direction, which can further reduce the residual amount of absorption liquid inside the filling mechanism.

[0039] It should be noted that when the filling rack 8 stops, the inertial force acting on the placement rack 14 is greater than the sum of the friction between the elastic sheet 20 and the filling rack 8, the pressure of the pressure plate 17 and the gravity of the placement rack 14 (and the filler 9). In this way, when the filling rack 8 stops, the placement rack 14 can rotate relative to the filling rack 8.

[0040] Furthermore, the shell 1 is provided with a liquid distributor 23, the liquid distributor 23 includes a main pipe 24 and a plurality of branch pipes 25, the main pipe 24 is connected to the addition pipe 4, the plurality of branch pipes 25 are fixedly connected to the main pipe 24, and the plurality of branch pipes 25 are all connected to the main pipe 24, and the main pipe 24 and the branch pipes 25 are both provided with a plurality of diversion holes 26. Specifically, the plurality of branch pipes 25 are evenly and symmetrically arranged on the main pipe 24, and the plurality of diversion holes 26 are respectively arranged below the main pipe 24 and the branch pipes 25, so that when the absorption liquid enters the inside of the main pipe 24 through the addition pipe 4, it will enter the plurality of branch pipes 25 respectively, and finally fall evenly to the packing mechanism through the plurality of diversion holes 26, so as to achieve the function of liquid diversion.

[0041] As another embodiment of the present invention, the plurality of flow diversion holes 26 decrease in size in a direction away from the central axis of the housing 1. Specifically, the absorption liquid flowing out of the liquid distributor 23 has a flow rate of the absorption liquid near the center of the packing mechanism greater than the flow rate of the absorption liquid away from the center of the packing mechanism, so that when the packing mechanism rotates, most of the absorption liquid will first fall to the center of the packing mechanism, and then diverge from the middle to the outside (such as Figure 4 As shown), the absorption liquid can cover the entire packing structure, thereby avoiding as much as possible the discharge of smoke without contacting the absorption liquid.

[0042] Furthermore, a filter screen 27 is provided on the air intake pipe 3. Specifically, the filter screen 27 is provided at the outlet end of the air intake pipe 3, and the filter screen 27 is preferably arc-shaped. When the absorption liquid falls on the surface of the filter screen 27, it will slide along the arc-shaped surface, thereby preventing the absorption liquid from entering the interior of the air intake pipe 3 as much as possible.

[0043] It should be noted that, when the absorption liquid falls from the filling mechanism, it will slide along the inner wall of the placement rack 14. Since the outlet of the air inlet pipe 3 is located at the bottom center of the filling mechanism, only a small part of the absorption liquid will fall above the air inlet pipe 3. Combined with the high-pressure flue gas ejected from the inside of the air inlet pipe 3, it will produce a large resistance to the absorption liquid entering the inside of the air inlet pipe 3. Therefore, with the cooperation of the filter 27, the divergent and falling absorption liquid, and the high-pressure flue gas, only a very small part of the absorption liquid will enter the inside of the air inlet pipe 3, and its influence on the entire capture process is extremely small and can be ignored.

[0044] As another embodiment of the present invention, a mounting portion 28 is slidably provided on the air intake pipe 3, and a second spring 29 is provided between the air intake pipe 3 and the mounting portion 28. A transmission rod 30 is provided on the placement frame 14, and an abutment plate 31 is provided on the mounting portion 28. The abutment plate 31 is located on the movement stroke of the transmission rod 30. Specifically, the transmission rod 30 is L-shaped, and includes a vertical section and a horizontal section. The end of the vertical section is fixedly connected to the retaining frame at the bottom of the placement frame 14. The mounting portion 28 is cylindrical and sleeved at the position of the outlet of the air intake pipe 3. One end of the second spring 29 is fixedly connected to the top of the air intake pipe 3, and the other end is fixedly connected to the inner top wall of the mounting portion 28. The abutment plate 31 is annular and is provided at the edge of the mounting portion 28 and is located on the movement stroke of the horizontal section of the transmission rod 30. The effect of such a setting is that when the driving motor 11 stops, the placement frame 14 will shake up and down under the action of the sliding portion 16 and the slide groove 15, thereby driving the transmission rod 30. It rotates and shakes up and down at the same time. During this process, when the transmission rod 30 moves up, the horizontal section of the transmission rod 30 abuts against the lower surface of the abutment plate 31, thereby driving the abutment plate 31, the mounting portion 28 and the filter 27 to move up synchronously and stretch the second spring 29. When the transmission rod 30 moves down, its horizontal section will move away from the abutment plate 31, and the mounting portion 28, the abutment plate 31 and the filter 27 will move down under the action of their own gravity and the elastic force of the second spring 29. This reciprocating process will drive the filter 27 to shake up and down to shake off the absorption liquid and impurities such as dust on the filter 27, so as to achieve the self-cleaning effect of the filter 27.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
