Abstract
Description
Technical Field
[0001] The invention relates to the technical field of flue gas treatment, and in particular to a flue gas carbon dioxide recovery and resource utilization device. Background Art
[0002] Carbon dioxide is an important industrial gas. In addition to nitrogen, which has the highest content, the flue gas produced by combustion in industrial production also contains a relatively high concentration of carbon dioxide. Recycling carbon dioxide for reuse can further reduce carbon emissions and turn carbon dioxide into treasure, which has extremely high economic value.
[0003] Among the existing carbon dioxide adsorption methods, the most mature and low-cost method is the adsorption method. The main principle of the adsorption method is to use solid adsorbents to adsorb carbon dioxide in the mixed gas. This principle is to select adsorbents that have stronger adsorption force on the carbon dioxide component in the mixed gas than other components based on the spatial structure and molecular polarity of carbon dioxide molecules. Due to the difference in the attractive force between the molecules of each component in the mixed gas and the active points on the surface of the adsorbent, when the mixed gas passes through the adsorbent carried by the adsorption bed under a certain pressure, the adsorbent selectively absorbs carbon dioxide, thereby achieving the separation and recovery of carbon dioxide gas.
[0004] In the prior art, solid amine particles are often used to adsorb carbon dioxide in flue gas. However, the solid amine particles need to be preheated before adsorption, and the flue gas needs to be filtered before adsorption can be performed. Flue gas itself is a high-temperature gas, and there is no device in the prior art that directly utilizes the heat of high-temperature flue gas, which leads to energy waste. At the same time, in the prior art, the preheating and adsorption of solid amine particles cannot be adjusted each time, and need to be treated separately, resulting in low efficiency.

[0028] (III) Beneficial effects
[0029] Compared with the prior art, the present invention provides a flue gas carbon dioxide recovery and resource utilization device, which has the following beneficial effects:
[0030] 1. The flue gas carbon dioxide recovery and resource utilization device is provided with an adsorption device, a heat exchange tube and a filter device. After the high-temperature flue gas passes through the filter device for heat filtration treatment, dust and particles in the flue gas are filtered out, and then the flue gas is transported to the adsorption device through the heat exchange tube. Since the heat exchange tube fits the bottom of the adsorption device, the high-temperature flue gas in the heat exchange tube exchanges heat with the solid amine particle module inside the adsorption device, thereby preheating the solid amine particle module, thereby achieving the effect of quickly using the solid amine particle module to adsorb carbon dioxide. At the same time, the preheating treatment of the high-temperature flue gas is utilized to achieve the effect of efficient utilization of resources.
[0031] 2. In the flue gas carbon dioxide recovery and resource utilization device, when the through hole at the bottom is connected with the through hole on the left, the high-temperature flue gas is transported upward from the gas pipe on the left, and is transported to the inside of the adsorption device from the heat exchange pipe on the left, and is adsorbed by the solid amine particle modules inside the two adsorption devices to achieve a better adsorption effect, and the high-temperature flue gas is transported from the air inlet pipe to the filter device, and is filtered by two partitions to achieve a better effect of filtering dust and particles in the flue gas. By setting the filtering device, the flue gas guiding and filtering effects are achieved.
[0032] 3. In the flue gas carbon dioxide recovery and resource utilization device, when the high-temperature flue gas is transported from the gas pipe on one side to the adsorption device, the airflow is from bottom to top, and the gas pipe on the other side is used to discharge the flue gas after adsorption, that is, to discharge the residual gas, and the airflow is from top to bottom. When the gas pipe transports the high-temperature flue gas, the airflow formed by the high-temperature flue gas acts on the baffle plate, pushing the baffle plate to seal the exhaust pipe, thereby completing the transportation of the high-temperature flue gas. When the gas pipe discharges the residual gas, the residual gas pushes the baffle plate to seal the gas pipe, and the residual gas is discharged from the exhaust pipe to achieve the effect of discharging the residual gas.
[0033] 4. The flue gas carbon dioxide recovery and resource utilization device ensures that the airflow can push the blocking plate to seal the exhaust pipe or the gas pipe through the design of the fourth rotating shaft, thereby achieving the effect of airflow guidance and better completing the effects of flue gas transportation and residual gas discharge.
[0034] 5. The flue gas carbon dioxide recovery and resource utilization device, the placement frame and the locking block drive the adsorption device to rotate, that is, the two solid amine particle modules are adjusted in the upper and lower positions. With the reciprocating movement of the movable plate, the placement frame operates in a rotating disk°-moving-rotating disk°-moving mode between the two movable grooves and the movable groove. When the placement frame of the solid amine particle module rotates, the solid amine particles located at the bottom exchange heat with the corresponding heat exchange tubes to achieve the preheating effect, and the solid amine particle module rotated to the top is directly passed by the flue gas to achieve the effect of adsorbing carbon dioxide.
[0035] 6. The flue gas carbon dioxide recovery and resource utilization device, when the high-temperature flue gas moves between the two adsorption devices, after two adsorptions and two heat exchanges, achieves the effect of absorbing the heat of the flue gas, reducing the heat in the flue gas, and achieving a better effect of exhausting the residual gas.
[0036] 7. In the flue gas carbon dioxide recovery and resource utilization device, the high-temperature flue gas enters the solid amine particle module in the second adsorption device for adsorption, and is also discharged through the heat exchange tube. The heat exchange tube exchanges heat with the solid amine particle module. When the filtering device is in operation, the conveying direction of the flue gas is reversed. At this time, the solid amine particle module in the second adsorption device achieves the effect of preheating before preheating due to the previous heat exchange, that is, the solid amine particle module undergoes two preheating treatments when it is in effect, achieving a better preheating treatment effect.

[0053] As the action frame 22 swings, the action frame 22 drives the connecting column 41 to swing back and forth through the connecting member 23, so that the fourth rotating shaft 45 rotates back and forth in the housing 37, so that the filter plate 38 moves between the two sides of the through hole 39, so that the through hole 39 at the bottom is connected with the through hole 39 at the top in sequence, and the high-temperature flue gas is sequentially introduced into the two gas pipes 13. Figure 4 and Figure 5 As shown, when the through hole 39 at the bottom is connected with the through hole 39 on the left, the high-temperature flue gas is transported upward from the gas supply pipe 13 on the left, and is transported from the heat exchange pipe 11 on the left to the inside of the adsorption device 10, and is adsorbed by the solid amine particle modules inside the two adsorption devices 10 to achieve a better adsorption effect, and the high-temperature flue gas is transported from the air inlet pipe 16 to the filter device 15, and is filtered by two partitions 40 to achieve a better effect of filtering dust and particles in the flue gas. By setting the filter device 15, the effect of flue gas guiding and filtering is achieved.
[0054] The driving mechanism 12 includes an action frame 22 and a fixed plate 17, the fixed plate 17 is rotatably connected with a second rotating shaft 21 and a first rotating shaft 19, the first rotating shaft 19 is fixedly mounted with a disc 18, the second rotating shaft 21 is fixedly mounted with an action frame 22, a first action rod 20 is fixedly mounted at the edge of the disc 18, the first rotating shaft 19 and the first action rod 20 are within the frame of the action frame 22, and the first action rod 20 drives the action frame 22 to rotate around the second rotating shaft 21;
[0055] The upper and lower sections of the action frame 22 are fixedly mounted with connecting pieces 23, and the two connecting pieces 23 are respectively connected to the connecting column 41 and the heat exchange tube 11;
[0056] The connecting member 23 is composed of a telescopic rod and a rotating shaft, and the rotating shaft is rotatably connected to both ends of the connecting member 23 .
[0057] The first rotating shaft 19 is connected to the output shaft of an external rotating motor, and the external motor drives the first rotating shaft 19 to rotate, so that the first action rod 20 rotates around the first rotating shaft 19, and the first action rod 20 drives the action frame 22 to swing back and forth. By utilizing the connection method of the connecting piece 23, the action frame 22 drives the fourth rotating shaft 45 to swing back and forth, and drives the card bar 26 to move back and forth.
[0058] The exhaust pipe 14 is installed on the side of the gas pipe 13, and a hinge 43 is fixedly installed at the connection between the exhaust pipe 14 and the gas pipe 13. A blocking plate 44 is fixed on the hinge 43, and the blocking plate 44 rotates at the connection between the gas pipe 13 and the exhaust pipe 14 through the hinge 43;
[0059] The blocking plate 44 is installed in an inclined manner in the air delivery pipe 13 by the elastic force of the hinge 43 , and the shape of the blocking plate 44 is adapted to the exhaust pipe 14 .
[0060] When the high-temperature flue gas is transported from the air pipe 13 on one side to the adsorption device 10, the airflow is from bottom to top, and the air pipe 13 on the other side is used to discharge the flue gas after adsorption, that is, to discharge the residual gas, and the airflow is from top to bottom. When the air pipe 13 transports the high-temperature flue gas, the airflow formed by the high-temperature flue gas acts on the blocking plate 44, pushing the blocking plate 44 to seal the exhaust pipe 14, thereby completing the transportation of the high-temperature flue gas. When the air pipe 13 discharges the residual gas, the residual gas pushes the blocking plate 44 to seal the air pipe 13, and the residual gas is discharged from the exhaust pipe 14 to achieve the effect of discharging the residual gas. The design of the fourth rotating shaft 45 ensures that the airflow can push the blocking plate 44 to seal the exhaust pipe 14 or the air pipe 13, thereby achieving the effect of airflow guidance and better completing the effects of flue gas transportation and residual gas discharge.
[0061] The adsorption device 10 includes a pipe shell 24, and two ends of the two pipe shells 24 that are away from each other are each provided with two movable grooves 30, and a movable groove 31 is provided on the inner wall of the pipe shell 24 between the two movable grooves 30, and an adsorption mechanism is movably engaged in the movable groove 31 and the movable groove 30;
[0062] The adsorption mechanism moves between the two movable grooves 30 and the movable groove 31 , and the adsorption mechanism is preheated by heat conduction between the adsorption device 10 and the heat exchange tube 11 .
[0063] A moving plate 27 is slidably mounted on one end of the two pipe housings 24 that are close to each other. A slide groove 42 is provided at the bottom of the pipe housing 24. A clamping strip 26 is slidably mounted in the two slide grooves 42. The clamping strip 26 is connected to the connecting piece 23 at the upper end of the action frame 22, and the clamping strip 26 is movably connected to the action frame 22 through the connecting piece 23.
[0064] The clamping strip 26 is fixedly connected to the moving plate 27 , and the rotation of the action frame 22 drives the connecting member 23 to swing, thereby driving the clamping strip 26 to slide in the locking block 32 , and then the moving plate 27 reciprocates in the pipe housing 24 .
[0065] The movable plate 27 is movably connected with a second action rod 28, and a spirally arranged engaging groove 29 is provided on the circumferential surface of the second action rod 28. A engaging rod 25 is fixedly installed on the side of the movable plate 27, and the engaging rod 25 is interactively engaged in the engaging groove 29. Through the engaging effect of the engaging rod 25 and the engaging groove 29, as the movable plate 27 reciprocates left and right, the second action rod 28 operates in a rotation-movement-rotation mode with the movable plate 27;
[0066] The second action rod 28 is fixedly connected to the adsorption mechanism, and the second action rod 28 drives the adsorption mechanism to operate in the pipeline housing 24 .
[0067] The adsorption mechanism includes a placement frame 33, and two snap-fit blocks 32 are symmetrically installed on the outside of the placement frame 33. The two snap-fit blocks 32 are snap-fitted into the movable groove 31 or the movable groove 30, and move in the movable groove 31 and rotate in the movable groove 30;
[0068] A partition plate 34 is fixedly installed at the center of the inner circle of the placement frame 33. The partition plate 34 is arranged corresponding to the locking block 32. The partition plate 34 divides the inner circle of the placement frame 33 into two parts, and a solid amine particle module is placed in each part.
[0069] The partition plate 34 is rotatably connected to a third rotating shaft 35 , and the third rotating shaft 35 is rotatably connected to a baffle 36 , and the baffle 36 is a semicircular plate. The baffle 36 moves inside the pipeline housing 24 as the placement frame 33 moves, and shields the solid amine particle module located below the partition plate 34 .
[0070] The movable plate 27 moves left and right in the pipe housing 24 along with the card strip 26. When the card strip 26 moves from left to right, at the beginning, the placement frame 33 and the engaging block 32 are movably engaged in the movable groove 30. As the movable plate 27 moves, the second action rod 28 moves along with the movement of the movable plate 27, so that the engaging block 32 slides on the engaging block 32. When the engaging block 32 is movably engaged in another movable groove 30, the engaging block 32 is blocked by the side of the movable groove 30. As the movable plate 27 continues to move, the movable plate 27 drives the engaging rod 25 to slide in the engaging groove 29, so that the second action rod 28 rotates along with the movement of the movable plate 27. The position of the engaging rod 25 in the engaging groove 29 is adjusted, so that the driven adsorption device of the placement frame 33 and the engaging block 32 is 108° rotation, that is, the two solid amine particle modules are adjusted in the upper and lower positions. With the reciprocating movement of the movable plate 27, the placement frame 33 operates between the two movable grooves 30 and the movable groove 31 in the manner of rotating the disk 180°-moving-rotating the disk 180°-moving. When the placement frame 33 of the solid amine particle module rotates, the solid amine particles located at the bottom exchange heat with the corresponding heat exchange tubes 11 to achieve the preheating effect, and the solid amine particle module rotated to the top is directly passed by the flue gas to achieve the effect of adsorbing carbon dioxide. When the high-temperature flue gas moves between the two adsorption devices 10, after two adsorptions and two heat exchanges, the effect of absorbing the heat of the flue gas is achieved, thereby reducing the heat in the flue gas and achieving a better effect of discharging the residual gas.
[0071] The high-temperature flue gas is adsorbed by the solid amine particle module in the second adsorption device 10, and is discharged through the heat exchange tube 11. The heat exchange tube 11 exchanges heat with the solid amine particle module. When the filtering device 15 is in operation, the conveying direction of the flue gas is reversed. At this time, the solid amine particle module in the second adsorption device 10 achieves the effect of preheating before preheating due to the last heat exchange, that is, the solid amine particle module undergoes two preheating treatments when it is in effect, achieving a better preheating treatment effect.
[0072] When using,
[0073] Step 1: The first rotating shaft 19 is connected to the output shaft of the external rotating motor, and the external motor drives the first rotating shaft 19 to rotate, so that the first action rod 20 rotates around the first rotating shaft 19, and the first action rod 20 drives the action frame 22 to swing back and forth. By using the connection method of the connecting member 23, the action frame 22 drives the fourth rotating shaft 45 to swing back and forth, and drives the card bar 26 to move back and forth;
[0074] Step 2: As the action frame 22 swings, the action frame 22 drives the connecting column 41 to swing back and forth through the connecting piece 23, so that the fourth rotating shaft 45 rotates back and forth in the housing 37, so that the filter plate 38 moves on both sides and between the through holes 39, so that the through holes 39 at the bottom are connected with the through holes 39 at the top in sequence, and the high-temperature flue gas is passed into the two gas pipes 13 in sequence;
[0075] Step 3: The moving plate 27 moves left and right in the pipe housing 24 along with the card strip 26. When the card strip 26 moves from left to right, at the beginning, the placement frame 33 and the snap block 32 are movably snapped in the movable groove 30. As the moving plate 27 moves, the second action rod 28 moves along with the movement of the moving plate 27, so that the snap block 32 slides on the snap block 32. When the snap block 32 is movably snapped in another movable groove 30, the snap block 32 is blocked by the side of the movable groove 30. As the moving plate 27 continues to move, the moving plate 27 drives the snap rod 25 to slide in the snap groove 29, so that the second action rod 28 rotates along with the movement of the moving plate 27. The position of the snap rod 25 in the snap groove 29 is adjusted so that the placement frame 33 and the snap block 32 are snapped. The adsorption device rotates 108°, that is, the two solid amine particle modules are adjusted in the up and down positions. With the reciprocating movement of the movable plate 27, the placement frame 33 operates between the two movable grooves 30 and the movable groove 31 in the manner of rotating the disk 180°-moving-rotating the disk 180°-moving. When the placement frame 33 of the solid amine particle module rotates, the solid amine particles located at the bottom exchange heat with the corresponding heat exchange tubes 11, while the solid amine particle module rotated to the top is directly passed by the flue gas, thereby achieving the effect of adsorbing carbon dioxide. Moreover, when the high-temperature flue gas moves between the two adsorption devices 10, after two adsorptions and two heat exchanges, the heat of the flue gas is absorbed, the heat in the flue gas is reduced, and the effect of better exhausting the residual gas is achieved.
[0076] Step 4: When the high-temperature flue gas is transported from the gas pipe 13 on one side to the adsorption device 10, the airflow is from bottom to top, and the gas pipe 13 on the other side is used to discharge the adsorbed flue gas, that is, to discharge the residual gas, and the airflow is from top to bottom. When the gas pipe 13 transports the high-temperature flue gas, the airflow formed by the high-temperature flue gas acts on the blocking plate 44, pushing the blocking plate 44 to seal the exhaust pipe 14, thereby completing the transportation of the high-temperature flue gas. When the gas pipe 13 discharges the residual gas, the residual gas pushes the blocking plate 44 to seal the gas pipe 13, and the residual gas is discharged from the exhaust pipe 14, achieving the effect of discharging the residual gas.
