It is one of the main sources of PM2.5 in the air and one of the major contributors to the greenhouse effect, second only to CO2.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a capture and recovery mechanism, can eliminate the need for traditional floor-mounted equipment, shorten the flue gas treatment process, divide the pipeline into an inlet pipe, a capture pipe, and an outlet pipe, and set up a recovery pipe at the bottom of the capture pipe. With the help of a through groove, a support rotating rod, and other structures, the capture and recovery of flue gas carbon is integrated. During the flue gas transmission process, the honeycomb carbon adsorption plate directly completes the adsorption of flue gas carbon in the capture pipe. After the adsorption is saturated, the support rotating rod is driven by a servo motor to rotate and transfer the carbon into the recovery pipe. The carbon in the flue gas is quickly released and recovered by direct heating lamps and guide fans, while restoring the activity of the honeycomb carbon. This series of designs greatly reduces the flue gas retention and transfer time and improves the carbon capture efficiency.

[0019] 2. This application can further improve the overall carbon capture efficiency by setting up a pretreatment mechanism. Cooling water or chemical liquid can be introduced through the liquid inlet at the top of the cooler. The array of fine atomizing nozzles on both sides of the bottom forms two atomizing curtains, which can pre-cool, clean and chemically react the non-carbon components in the flue gas, reduce the interference of impurities on the subsequent adsorption of honeycomb carbon, and at the same time reduce the flue gas temperature to optimize the adsorption conditions. The flap between the two curtains is pushed and flipped when the flue gas passes through, which reduces the flue gas velocity through mechanical obstruction and turbulence, so that the flue gas stays in the capture tube for a longer time and has more sufficient contact with the honeycomb carbon, thereby improving the adsorption efficiency.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A flue gas carbon capture device includes an inlet pipe 1, a capture pipe 2 fixedly connected to the right side of the inlet pipe 1, an outlet pipe 3 fixedly connected to the right side of the capture pipe 2, a recovery pipe 4 fixedly connected to the bottom of the capture pipe 2, a capture and recovery mechanism 5 movably connected to the inner side of the capture pipe 2 and the recovery pipe 4, and a pretreatment mechanism 6 movably connected to the inner side of the inlet pipe 1.

[0030] The capture and recovery mechanism 5 includes a through groove 51 opened on the corresponding side of the capture tube 2 and the recovery tube 4. A support rod 52 is rotatably connected to the inner side of the through groove 51. Sealing baffles 53 are fixedly connected to the left and right sides of the support rod 52. A heat-resistant elastic sealing ring 54 is fixedly connected to the outer side of the sealing baffle 53. A sealing groove 55 is opened on the inner side of the through groove 51. The heat-resistant elastic sealing ring 54 is snapped into the inner side of the sealing groove 55. A support frame 56 is fixedly connected to the top and bottom of the support rod 52. An adsorption and capture assembly 57 is movably connected inside the support frame 56. A replacement assembly 58 is movably connected to the rear side of the support rod 52. The replacement assembly 58 is movably connected to the rear side of the capture tube 2.

[0031] In this embodiment: Traditional methods for capturing carbon in flue gas typically use a separate ground-mounted device, resulting in a long overall workflow and increased flue gas retention and transfer time. The improved solution eliminates this separate ground-mounted structure. Instead, the traditional exhaust gas pipeline is divided into three sections at the inflection point: inlet pipe 1, capture pipe 2, and outlet pipe 3. A recovery pipe 4, the same size as the capture pipe 2, is located at the bottom of the capture pipe 2. A direct heating lamp 7 for direct heating is installed on the right side of the recovery pipe 4, and a guide pipe for flue gas is installed on the left side. The carbon guide fan 8 and the capture pipe 2 and recovery pipe 4 are directly connected by three sets of through grooves 51. The through grooves 51 connect the interior of the two pipes. A support rod 52 is provided at the center of the through groove 51. The left and right sides of the support rod 52 are respectively provided with sealing baffles for sealing the through groove 51. When the capture pipe 2 adsorbs and captures carbon in the flue gas and the recovery pipe 4 heats and recovers carbon from the bottom of the flue gas, the sealing baffles will close the through groove 51 and achieve sealing by engaging the sealing groove 55 inside the through groove 51 with the heat-resistant elastic sealing rings 54 on both sides. To prevent flue gas overflow or carbon backflow, the adsorption capture component 57 and the replacement component achieve the following effects: When flue gas passes through the honeycomb carbon adsorption plate 57d, the honeycomb carbon adsorption plate 57d captures and adsorbs the carbon in the flue gas into its own interior until saturation. The telescopic rod and its internal compression spring 57c can buffer the impact of flue gas flow, maintain the stable gas capture performance of the honeycomb carbon adsorption plate 57d, and adapt to thermal expansion and contraction, avoiding the impact of rigidity on gas flow and capture efficiency. The servo motor 58a on the rear side of the capture tube 2 is activated, and the three sets of... The support rod 52 rotates in the same direction, causing the saturated honeycomb carbon adsorption plate 57d to rotate to the inside of the recovery pipe 4, and the reactivated honeycomb carbon adsorption plate 57d to rotate to the inside of the capture pipe 2. After the rotation is completed, the heat-resistant elastic sealing ring 54 will re-clamp into the sealing groove 55 to achieve a seal. At the same time, flue gas transmission and capture continue. Inside the recovery pipe 4, the direct heating lamp 7 directly heats the three sets of honeycomb carbon adsorption plates 57d in a straight line, causing them to release internal flue gas carbon due to high temperature and promote activity recovery. The released flue gas carbon is guided to the outlet for recovery by the guide fan 8.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, the pretreatment mechanism 6 includes a cooler 61 fixedly connected to the top of the air inlet pipe 1, and a liquid inlet 62 fixedly connected to the top of the cooler 61.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, arrays of fine atomizing nozzles 63 are fixedly connected to both sides of the bottom of the cooler 61.

[0034] Specifically, such as Figure 1 , Figure 2, Figure 6 As shown, a support frame 64 is fixedly connected to the bottom of the inner side of the air inlet pipe 1, and a flap 65 is rotatably connected to the inner side of the support frame 64. The flap 65 is located at the bottom of the cooler 61.

[0035] In this embodiment: A cooler 61 is installed at the top of the air inlet pipe 1. The cooler 61 has a liquid inlet 62 at the top, which can be used to transport cooling water or chemical liquid. On both sides of the bottom of the cooler 61, an array of fine atomizing nozzles 63 are installed. These nozzles can form an atomized curtain of cooled chemical liquid or cooling water. When the flue gas passes through the two sets of curtains in succession, the curtains will react with the non-flue gas carbon in the flue gas in advance, reducing the flue gas temperature and cleaning impurities. In addition, in the middle of the two atomized curtains, that is, at the bottom of the cooler 61, there is a flap 65 supported by a support frame 64. When the flue gas passes through, the flap 65 will block the flue gas from the middle and flip with the push of the flue gas. This can convert the transmission speed of the flue gas into mechanical work to a certain extent, play a role in slowing down and turbulence, and thus improve the subsequent capture effect.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, the adsorption and capture assembly 57 includes a support ring 57a fixedly connected to the right side of the support frame 56, a telescopic column 57b fixedly connected to the left side of the support ring 57a, and a compression spring 57c fixedly connected to the inner side of the telescopic column 57b.

[0037] Specifically, such as Figure 3 , Figure 4 As shown, a honeycomb carbon adsorption plate 57d is fixedly connected to the left side of the telescopic column 57b.

[0038] In this embodiment: support frames 56 for supporting the honeycomb carbon adsorption plate 57d are respectively installed at the top and bottom of the support rotating rod 52. A support ring 57a is provided on the right side of the support frame 56. The honeycomb carbon adsorption plate 57d is connected to the support ring 57a through multiple telescopic rods and the compression springs 57c inside. When the flue gas passes through the honeycomb carbon adsorption plate 57d, the honeycomb carbon adsorption plate 57d will capture and adsorb the carbon in the flue gas into its own interior until it reaches saturation. The telescopic rods and the compression springs 57c inside can buffer the impact of the flue gas flow, so that the honeycomb carbon adsorption plate 57d maintains stable gas capture performance. At the same time, it can also adapt to thermal expansion and contraction, avoiding the impact of rigid fracture on gas flow and capture efficiency.

[0039] Specifically, such as Figure 3 , Figure 5As shown, the replacement assembly 58 includes a servo motor 58a fixedly connected to the rear side of the capture tube 2. The output end of the servo motor 58a is fixedly connected to a drive tooth 58b. The right side of the drive tooth 58b is meshed with a linkage tooth 58c. The linkage tooth 58c is fixedly connected to the outside of the support rod 52 near the air inlet pipe 1. The rear side of the support rod 52 near the air inlet pipe 1 is fixedly connected to a first pulley 58d. The rear side of the support rod 52 near the air outlet pipe 3 is fixedly connected to a second pulley 58e. The rear side of the capture tube 2 is rotatably connected to a third pulley 58f. The outer sides of the first pulley 58d, the second pulley 58e, and the third pulley 58f are all movably connected to a first transmission belt 58g.

[0040] Specifically, such as Figure 3 , Figure 5 As shown, a fourth pulley 58h is fixedly connected to the rear side of the third pulley 58f, a second transmission belt 58i is movably connected to the outer side of the fourth pulley 58h, a fifth pulley 58j is movably connected to the inner side of the second transmission belt 58i, and the fifth pulley 58j is fixedly connected to the rear side of the support rod 52 on the side away from the air inlet pipe 1 and the air outlet pipe 3.

[0041] In this embodiment: by activating the servo motor 58a on the rear side of the capture tube 2, the drive gear 58b at the output end of the servo motor 58a rotates, driving the outer linkage gear 58c to rotate. Since the linkage gear 58c is coaxially connected to the left support rotating rod 52, and the left support rotating rod 52 is also coaxially mounted with a first pulley 58d, the first pulley 58d is connected to the second pulley 58e and the third pulley 58f via a first transmission belt 58g. The second pulley 58e is coaxially connected to the right support rotating rod 52, and the third pulley 58f is rotatably connected to the top area of ​​the middle support rotating rod 52 on the rear side of the capture tube 2, thereby enabling the servo motor 58a to drive the two support rotating rods 52 to rotate in the same direction. In addition, the fourth pulley 58h, which is coaxially connected to the third pulley 58f, is linked to the fifth pulley 58j on the outer side of the middle support rotating rod 52 via a second transmission belt 58i, ultimately achieving the effect of the servo motor 58a driving the three sets of support rotating rods 52 to rotate in the same direction.

[0042] Specifically, such as Figure 1 , Figure 2 As shown, a direct heating lamp 7 is fixedly connected to the left side of the inner side of the recovery tube 4.

[0043] Specifically, such as Figure 2 As shown, a guide fan 8 is fixedly connected to the right side of the inner side of the recovery pipe 4.

[0044] In this example: the direct heating lamp 7 directly heats the three sets of honeycomb carbon adsorption plates 57d in a straight line, causing them to release the internal flue gas carbon under high temperature and promoting its activity recovery, while the flue gas carbon is guided to the outlet for recovery by the guide fan 8.

[0045] Working Principle: In flue gas carbon capture, existing technologies typically use separate ground-mounted equipment to capture and collect carbon from the flue gas, resulting in a longer overall process and increased flue gas retention and transfer time. This new method eliminates the need for a separate ground-mounted structure. Instead, the traditional exhaust gas pipeline is divided into three sections at the inflection point: inlet pipe 1, capture pipe 2, and outlet pipe 3. At the bottom of capture pipe 2, a recovery pipe 4 is installed for rapid carbon recovery. This recovery pipe 4 is the same size and dimensions as capture pipe 2, and a direct heating lamp 7 is installed on its right side for direct heating, while a guide fan 8 is installed on its left side to guide the carbon in the flue gas. Three sets of through grooves 51 are directly connected between capture pipe 2 and recovery pipe 4, connecting the capture pipe 2 and the recovery pipe. 4. The internal structure is connected by opening the channel, and a support rod 52 is set at the center of the through channel 51 for support. Sealing baffles for sealing the through channel 51 are set on the left and right sides of the support rod 52. These sealing baffles close the through channel 51 when the capture tube 2 adsorbs and captures carbon from the flue gas and when the bottom is heated to recover carbon from the flue gas. The baffles are sealed by heat-resistant elastic sealing rings 54 on both sides engaging with the sealing grooves 55 inside the through channel 51 to prevent flue gas overflow or carbon backflow. Support frames 56 for supporting the honeycomb carbon adsorption plate 57d are set at the top and bottom of the support rod 52. A support ring 57a is set on the right side of the support frame 56. The honeycomb carbon adsorption plate 57d is supported by multiple telescopic rods and its inner side pressure. Spring 57c is connected to support ring 57a, enabling the honeycomb carbon adsorption plate 57d to capture carbon from the flue gas as it passes through, adsorbing it until saturation. The telescopic rod and its internal compression spring 57c buffer the flow impact of the flue gas, maintaining the stable gas capture performance of the honeycomb carbon adsorption plate 57d. This also adapts to thermal expansion and contraction, preventing rigid breakage that could affect gas flow and capture efficiency. When nearing saturation and no longer supplying flue gas, the servo motor 58a located behind the capture tube 2 is activated, causing the drive gear 58b at the output of the servo motor 58a to rotate. The drive gear 58b then rotates in conjunction with its outer linkage gear 58c. The linkage gear 58c is coaxially connected to the left support rotating rod 52 and rotates in tandem with the left support rotating rod 52. The shaft also connects to the first pulley 58d, which is connected to the second pulley 58e and the third pulley 58f via the first transmission belt 58g. The second pulley 58e is coaxially connected to the right support rod 52, while the third pulley 58f is rotatably connected to the rear side of the capture tube 2, i.e., the top area of ​​the middle support rod 52. This allows the servo motor 58a to achieve the effect of rotating the two support rods 52 in the same direction. The fourth pulley 58h is coaxially connected to the third pulley 58f. The fourth pulley 58h is linked to the fifth pulley 58j on the outer side of the middle support rod 52 via the second transmission belt 58i. In summary, the servo motor 58a achieves the effect of rotating the three sets of support rods 52 in the same direction. When the support rods 52 rotate...The heat-resistant elastic sealing ring 54 on the outside of the sealed baffle will be squeezed, contracted, and detached from the sealing groove 55. The saturated honeycomb carbon adsorption plate 57d will rotate to the inside of the recovery pipe 4, and the reactivated honeycomb carbon adsorption plate 57d will rotate to the inside of the capture pipe 2. After the rotation is completed, the heat-resistant elastic sealing ring 54 will re-enter the sealing groove 55 to achieve a seal. At the same time, the flue gas transmission and capture of flue gas carbon will continue. Inside the recovery pipe 4, the three sets of honeycomb carbon adsorption plates 57d in a straight line are directly irradiated by the direct heating lamp 7, causing them to release the flue gas carbon inside due to high temperature and promoting their reactivation. The flue gas carbon is guided to the outlet for recovery by the guide fan 8. In order to further enhance the above-mentioned capture and recovery effect, a cooler 61 is provided at the top of the inlet pipe 1. The cooler 61 has a liquid inlet 62 at its top for supplying cooling water or chemical liquid. On both sides of the bottom of the cooler 61, inside the air inlet pipe 1, are arrayed fine atomizing nozzles 63. These nozzles form an atomized curtain of cooled chemical liquid or water. As flue gas passes through these two curtains, it pre-reacts with non-flue gas carbon, reducing temperature and cleaning impurities. Between the two atomized curtains, at the bottom of the cooler 61, is a flap 65 supported by a support frame 64. This flap blocks the flue gas from the middle and flips as the flue gas passes, converting the flue gas's velocity into mechanical work, thus slowing down and turbulent the flow, improving subsequent carbon capture. In summary, this optimizes the process of capturing flue gas carbon.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
