Description

Technical Field

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

[0002] Carbon dioxide capture technology is used to remove carbon dioxide from a gas stream or separate carbon dioxide as a gas product. Carbon dioxide capture technology can be divided into several categories such as chemical absorption, physical absorption, physical adsorption, membrane separation, cryogenic separation, etc. When applied, the capture method and equipment need to be selected according to the actual characteristics and parameters of the carbon dioxide emission source. Capturing and storing carbon dioxide generated in industrial production is an effective way to reduce carbon emissions.

[0003] When capturing carbon dioxide in industrial flue gas, the method of spraying a capture agent is usually adopted to make the carbon dioxide in the flue gas fully contact with the capture agent. However, in the existing capture equipment, due to the fixed positions of the spray pipes and the flue gas inlet, the contact time between carbon dioxide and the capture agent at different positions is not equal, resulting in the capture agent usually not being able to fully exert its efficiency, and thus leading to a low overall reaction efficiency. Moreover, a large amount of dust impurities are contained in industrial flue gas, and these impurities entering the capture agent will interfere with the subsequent separation of carbon dioxide.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] As Figure 1 、 Figure 3 、 Figure 4 、 Figure 8 As shown in

[0037] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 8As shown, the trapping structure 2 includes a discharge pipe 203, the inner side of the treatment tank 1 is fixedly connected with the discharge pipe 203, the side of the treatment tank 1 is fixedly connected with a spray pipe 201, the end of the spray pipe 201 is of an annular structure, the other side of the treatment tank 1 is fixedly connected with an air delivery pipe 202, the outer side of the discharge pipe 203 is rotatably connected with a rotary scraper 204, the rotary scraper 204 is of an inclined surface structure, and the inner side of the rotary scraper 204 is slidably connected with the discharge pipe 203, and the outer side of the rotary scraper 204 is slidably connected with the inner side wall of the treatment tank 1;

[0038] The pressurized capture agent solution is added through the spray pipe 201 and atomized through the nozzles on the bottom side. The flue gas enters the treatment tank 1 through the air delivery pipe 202 and reacts with the capture agent. The flue gas will flow downward on the outer side of the discharge pipe 203 and finally enter the inner side of the discharge pipe 203 for discharge. The outer side of the discharge pipe 203 is provided with a rotary scraper 204 of an inclined surface structure. When the rotary scraper 204 rotates, it will fully disturb the air flow in the treatment tank 1 to reduce the outflow speed of the flue gas, so as to increase the reaction time of the flue gas and the capture agent solution, so as to make full use of the capture agent to capture carbon dioxide in the flue gas. On the other hand, as the rotary scraper 204 rotates, the droplets attached to the side walls of the treatment tank 1 and the discharge pipe 203 can be scraped and concentrated at the bottom of the treatment tank 1 for convenient collection.

[0039] Specifically, as Figure 1 、 Figure 3 、 Figure 4 shown, the driving structure 3 includes an air suction fan 304, the top end of the discharge pipe 203 is rotatably connected with the air suction fan 304, the bottom side of the air suction fan 304 is fixedly connected with a central shaft rod 303, the bottom end of the central shaft rod 303 is rotatably connected with the treatment tank 1, the bottom end of the central shaft rod 303 is fixedly connected with a stirring paddle 308, the discharge pipe 203 is provided with a filter plate 302 on the top side of the air suction fan 304, a first motor 301 is installed on the side of the treatment tank 1, the output end of the first motor 301 is fixedly connected with a driving shaft 307, the end of the driving shaft 307 is fixedly connected with a second bevel gear 306, a first bevel gear 305 is fixedly connected to the central shaft rod 303, the first bevel gear 305 and the second bevel gear 306 are meshed with each other, and a tooth ring 310 is fixedly connected to the bottom end of the rotary scraper 204, and a transmission tooth 309 is meshed between the inner side of the tooth ring 310 and the first bevel gear 305, and the transmission tooth 309 is rotatably connected to the bottom end of the discharge pipe 203;

[0040] The intake fan 304 rotates and guides the airflow to flow towards the top side of the discharge pipe 203, and is discharged after being filtered by the filter plate 302. The stirring paddle 308 at the bottom side of the central shaft rod 303 will stir the mixed solution at the bottom side of the treatment tank 1 evenly to facilitate subsequent collection. On the other hand, while the first bevel gear 305 rotates, it can also drive the rotary scraper 204 to rotate further through the transmission effect of the transmission gear 309 and the toothed ring 310.

[0041] Specifically, as Figure 4 、 Figure 5 shown, the discharge structure 7 includes a liquid level sensor 701. The liquid level sensor 701 is installed at the bottom of the treatment tank 1. A liquid discharge port 702 is opened at the bottom of the treatment tank 1. A sealing plug 703 is slidably connected to the treatment tank 1 at the liquid discharge port 702. A fourth spring 704 is fixedly connected between the top end of the sealing plug 703 and the treatment tank 1. A release rod 705 is rotatably connected to the side of the treatment tank 1. The end of the release rod 705 has a protruding structure, and the protruding structure is eccentrically arranged. The protruding structure at the end of the release rod 705 abuts against the side of the sealing plug 703. The other end of the release rod 705 is slidably connected to a rotary cover 706. A fifth spring 707 is fixedly connected between the release rod 705 and the rotary cover 706. A clamping groove 708 is opened on each of the two sides of the treatment tank 1 opposite to the release rod 705. The side of the rotary cover 706 is clamped with the treatment tank 1 through the clamping groove 708;

[0042] The sprayed capture agent solution will finally settle to the bottom of the treatment tank 1 after being mixed with the flue gas. When the liquid level rises to the bottom end of the discharge pipe 203, the outside of the discharge pipe 203 is in a closed state. As the flue gas continues to be introduced, the pressure of the solution at the bottom side of the treatment tank 1 will increase. With the help of the liquid level sensor 701 at the bottom side of the treatment tank 1, the liquid level position can be timely known and the solution can be discharged. A liquid discharge port 702 is opened at the bottom side of the treatment tank 1. The user can lift the sealing plug 703 by rotating the release rod 705, and then open the liquid discharge port 702 to discharge the mixed liquid, which is convenient for the subsequent separation of carbon dioxide.

[0043] Specifically, as Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12As shown, the scrubbing structure 4 includes a scrubbing tank 401. One end of the gas delivery pipe 202 facing away from the treatment tank 1 is connected to the scrubbing tank 401. An air inlet pipe 402 is provided on the side of the scrubbing tank 401. One end of the air inlet pipe 402 located inside the scrubbing tank 401 is arranged at the bottom of the scrubbing tank 401. A partition plate 403 is provided inside the scrubbing tank 401. A wire mesh plate 404 is fixedly connected to the middle of the partition plate 403. A sewage discharge pipe 405 is opened at the bottom side of the scrubbing tank 401;

[0044] The inside of the scrubbing tank 401 is provided with a scrubbing solution for separating insoluble and partially reactive impurities in the flue gas. At the same time, a partition plate 403 is provided in the middle of the scrubbing tank 401. After some insoluble impurities in the gas enter the liquid, they will be isolated by the wire mesh plate 404 in the middle of the partition plate 403, facilitating subsequent centralized treatment. And the blockage of the wire mesh plate 404 can improve the scrubbing effect on the flue gas.

[0045] Specifically, as Figure 1 、 Figure 7 、 Figure 8 、 Figure 10 shown, the adjusting structure 5 includes a driving screw 502. A support plate 506 is threadedly connected to the driving screw 502. The support plate 506 is slidably connected to the inside of the scrubbing tank 401. A cleaning slide bar 504 is rotatably connected to the end of the support plate 506. A brush-like structure is provided on the cleaning slide bar 504. The top end of the cleaning slide bar 504 is slidably connected to the middle of the wire mesh plate 404. A telescopic groove 505 is opened in the middle of the cleaning slide bar 504. A second motor 501 is installed at the top of the scrubbing tank 401. The output end of the second motor 501 is fixedly connected to a telescopic shaft 503. The telescopic shaft 503 is slidably connected to the inside of the cleaning slide bar 504 through the telescopic groove 505;

[0046] Rotating the driving screw 502 adjusts the position of the support plate 506. At the same time, a second motor 501 is installed on the top side of the scrubbing tank 401. Driven by the second motor 501, the telescopic shaft 503 can drive the cleaning slide bar 504 to rotate through the telescopic groove 505. The cleaning slide bar 504 can stir the scrubbing liquid while rotating. At the same time, the user can also adjust the height of the support plate 506, and use the brush structure provided on the cleaning slide bar 504 to clean the bottom side of the wire mesh plate 404 to ensure that the flue gas can pass through the wire mesh plate 404 normally after scrubbing.

[0047] Specifically, as Figure 1 、 Figure 8 、 Figure 10 、 Figure 12As shown, the separation structure 6 includes an extension block 602. The side of the partition plate 403 is slidably connected to the extension block 602. A first spring 603 is fixedly connected between the extension block 602 and the partition plate 403. The side of the extension block 602 is threadedly connected to the driving screw rod 502. The side of the extension block 602 is slidably connected to an inclined surface clamping block 605. A second spring 606 is fixedly connected between the inclined surface clamping block 605 and the extension block 602. A number of inclined surface grooves 607 are sequentially and equidistantly formed inside the scrubbing box 401. The inner side of the inclined surface groove 607 is of an inclined surface structure. The side of the scrubbing box 401 is slidably connected to a pushing plate 604. The extension block 602 is vertically slidably connected to the side of the pushing plate 604. The other side of the pushing plate 604 abuts against a control rotating rod 601. The end of the control rotating rod 601 is rotatably connected to the scrubbing box 401. The top of the control rotating rod 601 is slidably connected to a positioning rod 608. A third spring 609 is fixedly connected between the positioning rod 608 and the control rotating rod 601. A positioning hole 610 is formed on the side of the scrubbing box 401. The end of the positioning rod 608 is engaged with the scrubbing box 401 through the positioning hole 610;

[0048] When it is necessary to adjust the distance between the partition plate 403 and the support plate 506, the user can turn the control rotating rod 601 to one side. At this time, the pushing plate 604 loses support. Under the push of the first spring 603, the extension block 602 disengages from the driving screw rod 502. After losing the support of the thread structure on the driving screw rod 502, the partition plate 403 slides. At this time, since the inclined surface clamping block 605 on the side of the extension block 602 will be engaged with the adjacent inclined surface groove 607 formed inside the scrubbing box 401, the partition plate 403 is supported again. At this time, when the user rotates the driving screw rod 502, only the height of the support plate 506 can be adjusted. When the control rotating rod 601 rotates again and is fixed through the positioning rod 608 and the positioning hole 610, as the extension block 602 slides, the inclined surface clamping block 605 on its side will disengage from the inclined surface groove 607, and the extension block 602 will be threadedly connected to the driving screw rod 502 again. On the other hand, when there are more impurities accumulated in the scrubbing box 401, the user can lower the height of the partition plate 403 to concentrate the impurities in the solution. At this time, with the agitation of the cleaning slide rod 504, the impurities in the solution can be quickly discharged through the sewage discharge pipe 405, which is convenient for cleaning.

[0049] When the present invention is in use, first, a cylindrical discharge pipe 203 is fixed in the middle of the treatment tank 1. The spray pipe 201 is arranged in a ring outside the discharge pipe 203. And the flue gas is input from one side of the treatment tank 1 through the gas transmission pipe 202. During the process of carbon dioxide capture, a pressurized capture agent solution is added through the spray pipe 201 and atomized through the nozzles on the bottom side. The flue gas enters the treatment tank 1 through the gas transmission pipe 202 and reacts with the capture agent. The flue gas will flow downward outside the discharge pipe 203 and finally enter the inside of the discharge pipe 203 for discharge. A rotary scraper 204 with an inclined surface structure is arranged outside the discharge pipe 203. When the rotary scraper 204 rotates, it will fully disturb the airflow in the treatment tank 1 to reduce the outflow speed of the flue gas, so as to increase the reaction time of the flue gas and the capture agent solution, and make full use of the capture agent to capture carbon dioxide in the flue gas. On the other hand, as the rotary scraper 204 rotates, the droplets attached to the side walls of the treatment tank 1 and the discharge pipe 203 can be scraped and concentrated to the bottom of the treatment tank 1 for convenient collection. Through the first motor 301 installed on the side of the treatment tank 1, the drive shaft 307 can be driven to rotate. When the drive shaft 307 rotates, through the transmission effect of the first bevel gear 305 and the second bevel gear 306, the central shaft rod 303 in the middle of the treatment tank 1 can be driven to rotate, so that the suction fan 304 at the top rotates and guides the airflow to flow to the top side of the discharge pipe 203, and is discharged after being filtered by the filter plate 302. And the stirring paddle 308 at the bottom side of the central shaft rod 303 will stir the mixed solution at the bottom side of the treatment tank 1 evenly for convenient subsequent collection. On the other hand, when the first bevel gear 305 rotates, it can also drive the rotary scraper 204 to rotate further through the transmission effect of the transmission teeth 309 and the toothed ring 310. The sprayed capture agent solution will finally settle to the bottom of the treatment tank 1 after mixing with the flue gas. When the liquid level rises to the bottom end of the discharge pipe 203, the outside of the discharge pipe 203 is in a closed state. And as the flue gas continues to be introduced, the pressure of the solution at the bottom side of the treatment tank 1 will increase. With the help of the liquid level sensor 701 at the bottom side of the treatment tank 1, the liquid level position can be known in time, and the solution can be discharged. A liquid discharge port 702 is provided at the bottom side of the treatment tank 1. The user can lift the sealing plug 703 by rotating the release rod 705, and then open the liquid discharge port 702 to discharge the mixed liquid, which is convenient for subsequent separation of carbon dioxide. Before the flue gas enters the treatment tank 1, it needs to be discharged into the scrubbing tank 401 through the inlet pipe 402. The end of the inlet pipe 402 is located at the bottom position of the scrubbing tank 401. At the same time, a scrubbing solution is provided inside the scrubbing tank 401 to separate the insoluble and partially reactive impurities in the flue gas. At the same time, a partition plate 403 is provided in the middle of the scrubbing tank 401. After some insoluble impurities in the gas enter the liquid, they will be isolated by the mesh plate 404 in the middle of the partition plate 403 for convenient subsequent centralized treatment. And the blockage of the mesh plate 404 can improve the scrubbing effect on the flue gas.A cleaning slide bar 504 is provided at the bottom side of the partition plate 403. The cleaning slide bar 504 is rotatably connected to the support plate 506. The user can adjust the position of the support plate 506 by rotating the driving screw rod 502. At the same time, a second motor 501 is installed on the top side of the scrubbing tank 401. Driven by the second motor 501, the telescopic shaft 503 can drive the cleaning slide bar 504 to rotate through the telescopic groove 505. The cleaning slide bar 504 can stir the scrubbing liquid while rotating. At the same time, the user can also adjust the height of the support plate 506, and clean the bottom side of the mesh plate 404 through the brush structure provided on the cleaning slide bar 504, ensuring that the flue gas can pass through the mesh plate 404 normally after cleaning. In order to facilitate the adjustment of the position of the partition plate 403, an extension block 602 is provided on the side of the partition plate 403. When the user rotates the control lever 601, the side of the control lever 601 will push the pushing plate 604, so that the end of the extension plate is threadedly connected to the side of the driving screw rod 502. At this time, when the user rotates the driving screw rod 502, the partition plate 403 and the support plate 506 can be driven to move synchronously. When it is necessary to adjust the distance between the partition plate 403 and the support plate 506, the user can turn the control lever 601 to one side. At this time, the pushing plate 604 loses support, and the extension block 602 is pushed by the first spring 603 to disengage from the driving screw rod 502. After losing the support of the thread structure on the driving screw rod 502, the partition plate 403 slides. At this time, since the inclined surface block 605 on the side of the extension block 602 will engage with the adjacent inclined surface groove 607 opened inside the scrubbing tank 401, the partition plate 403 is supported again. At this time, when the user rotates the driving screw rod 502, only the height of the support plate 506 can be adjusted. When the control lever 601 rotates again and is fixed through the positioning rod 608 and the positioning hole 610, as the extension block 602 slides, the inclined surface block 605 on its side will disengage from the inclined surface groove 607, and the extension block 602 will be threadedly connected to the driving screw rod 502 again. On the other hand, when there are more impurities accumulated in the scrubbing tank 401, the user can lower the height of the partition plate 403 to concentrate the impurities in the solution. At this time, with the agitation of the cleaning slide bar 504, the impurities in the solution can be quickly discharged through the drain pipe 405, which is convenient for cleaning.
