Description

Technical Field

[0001] The present invention relates to the technical field of chemical towers, and specifically relates to an efficient and energy-saving carbon dioxide absorption tower. Background Art

[0002] In the context of the global response to climate change and the active promotion of carbon emission reduction, carbon dioxide capture technology has become a research hotspot and key demand. Efficiently separating and capturing carbon dioxide from industrial waste gas is of great significance for achieving the carbon neutrality goal. As the core equipment, the performance of the carbon dioxide absorption tower directly affects the efficiency and cost of carbon capture.

[0003] However, the position of the liquid distributor inside the traditional carbon dioxide absorption tower is fixed, and it is difficult for the liquid distributor to achieve uniform spraying of the absorption liquid, resulting in insufficient contact between the absorption liquid and the carbon dioxide-containing gas, limited gas-liquid contact area and contact time, and low carbon dioxide absorption efficiency.

[0004] The operation of replacing the internal packing in the traditional absorption tower is complex. It is necessary to manually dig out the internal packing from the maintenance port, which consumes a lot of manpower and time. The packing is usually fixed in a specific position, and it is difficult to conveniently replace the packing in different directions, resulting in high manual labor intensity and low maintenance efficiency. Moreover, the design of the equipment maintenance port is unreasonable, and it is inconvenient to open and close. During the maintenance process, it is difficult for the staff to quickly enter the tower to check, repair and replace the components, affecting the normal operation time of the equipment.

[0005] The installation process of the packing support structure in the traditional absorption tower is cumbersome, with a large assembly difficulty, requiring a lot of manpower and time costs, and the stability of the support is poor. Problems such as loosening may occur during long-term operation, affecting the normal operation of other structures inside the tower, and thus reducing the overall performance of the absorption tower.

Specific embodiments

[0041] 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 embodiments.

[0042] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 , Figure 11 and Figure 15As shown in the figure, an efficient and energy-saving carbon dioxide absorption tower according to the present invention includes a tower body 1, a main structure 2 provided on the tower body 1, an adjustment structure 3 provided inside the tower body 1, two support structures 4 provided inside the tower body 1, a rotating packing structure 5 provided on the support structure 4, a limiting structure 6 provided on the rotating packing structure 5, and two opening and closing structures 7 provided on the tower body 1;

[0043] The main structure 2 includes an exhaust pipe 201 and a liquid inlet pipe 202. The exhaust pipe 201 is provided at the top of the tower body 1, and an L-shaped liquid inlet pipe 202 is provided on the side wall of the top of the tower body 1. One end of the liquid inlet pipe 202 extends into the interior of the tower body 1, and the end of the liquid inlet pipe 202 is rotatably connected to a liquid distributor 205 through a rotary joint;

[0044] The adjusting structure 3 includes two mounting rings 301 and a gear ring 302. Two mounting rings 301 are fixedly connected to the inside of the tower body 1. A gear ring 302 is provided on the liquid distributor 205. The two mounting rings 301 are respectively attached to the upper and lower sides of the gear ring 302. A first energy-saving motor 303 is fixedly connected to the mounting ring 301. The output end of the first energy-saving motor 303 is fixedly connected to a first gear 304. The first gear 304 meshes with the gear ring 302. A protective housing 305 is sleeved and installed outside the first energy-saving motor 303. A plurality of first ball bearings 306 are circumferentially arranged on the mounting ring 301. The first ball bearings 306 are in rolling connection with the gear ring 302. A liquid redistributor 206 is provided inside the tower body 1 between the two rotating packing structures 5. A liquid collecting pool 207 is provided at the bottom end inside the tower body 1. An air inlet pipe 203 is provided on the side wall at the bottom end of the tower body 1. A liquid discharge pipe 204 is provided on the side wall at the bottom end of the tower body 1. The liquid discharge pipe 204 extends into the liquid collecting pool 207. When the absorption tower body 1 operates, the first energy-saving motor 303 is turned on. The first energy-saving motor 303 drives the first gear 304 to rotate. The first gear 304 meshes with the gear ring 302, thereby driving the liquid distributor 205 to rotate. The first ball bearings 306 are in rolling connection with the gear ring 302, greatly reducing the friction force when the gear ring 302 rotates. According to actual requirements, the rotation speed of the first energy-saving motor 303 is adjusted, so as to control the rotation speed of the liquid distributor 205, and adjust the spraying angle and the centrifugal force of the liquid spraying, so that the absorption liquid can be more evenly distributed on the tower cross-section. The gas containing carbon dioxide enters the inside of the tower body 1 from the air inlet pipe 203 and flows upward. The absorption liquid enters from the liquid inlet pipe 202 and is evenly sprayed into the tower body 1 through the rotating liquid distributor 205. Under the action of gravity, the absorption liquid flows downward and contacts the rising gas containing carbon dioxide in a countercurrent manner, and an absorption reaction occurs. The carbon dioxide is absorbed by the absorption liquid. After the first absorption, part of the absorption liquid will flow between the two rotating packing structures 5. The liquid redistributor 206 will redistribute this part of the absorption liquid to make it more evenly distributed to the lower packing area, further improving the absorption efficiency. The absorbed liquid flows into the liquid collecting pool 207 at the bottom of the tower body 1, and then is discharged through the liquid discharge pipe 204 for subsequent treatment. The gas from which carbon dioxide has been absorbed is discharged from the exhaust port at the top end.

[0045] Specifically, such as Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 14As shown in the figure, the support structure 4 includes a fixed seat 401 and a socket 402. Two sets of circumferentially arrayed fixed seats 401 are fixedly connected inside the tower body 1, and two sets of circumferentially arrayed sockets 402 are fixedly connected inside the tower body 1. Each set of the fixed seats 401 has six, and each set of the sockets 402 has six. An L-shaped plug rod 403 is inserted into the socket 402, and a support plate 406 is fixedly connected to the plug rod 403; a rotating seat 407 is fixedly connected to the bottom end of the support plate 406, a rotating sleeve 408 is rotatably connected to the rotating seat 407, a threaded sleeve 409 is rotatably connected to the fixed seat 401, a first screw rod 410 is rotatably connected to the rotating sleeve 408, and the first screw rod 410 is threadedly connected to the threaded sleeve 409. A triangular structure is jointly formed among the threaded sleeve 409, the first screw rod 410, the rotating sleeve 408, the support plate 406 and the side wall of the tower body 1; pin holes 404 are provided on both the socket 402 and the plug rod 403, and a pin plate 405 is inserted into the pin holes 404; during the construction of the tower body 1, inside the tower body 1, two sets of circumferentially arrayed fixed seats 401 and sockets 402 are respectively fixedly installed, with six in each set of the fixed seats 401 and sockets 402, ensuring that they are firmly connected inside the tower body 1 to provide a stable foundation for subsequent installation. The rotating seat 407 is fixedly connected to the bottom end of the support plate 406, the end of the first screw rod 410 is threadedly connected to the threaded sleeve 409, and then the plug rod 403 is inserted into the socket 402. After the plug rod 403 is completely inserted, the pin plate 405 can be completely nailed into the pin holes 404 to complete the installation of the support plate 406. By rotating the first screw rod 410, the oblique support force of the first screw rod 410, the rotating sleeve 408 and the threaded sleeve 409 on the support plate 406 can be adjusted, so that a stable triangular structure is formed among the threaded sleeve 409, the first screw rod 410, the rotating sleeve 408, the support plate 406 and the side wall of the tower body 1, enhancing the stability of the support.

[0046] Specifically, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 12 , Figure 13 , Figure 14 and Figure 15As shown, the rotary packing structure 5 includes an installation box 501 and a second energy-saving motor 502 fixedly connected to the inside of the installation box 501. The bottom ends of two of the support plates 406 are fixedly connected to the installation box 501. The output end of the second energy-saving motor 502 is fixedly connected to a second gear 503. A connecting shaft 504 is rotatably connected to the installation box 501. The bottom end of the connecting shaft 504 is fixedly connected to a third gear 505. The second gear 503 meshes with the third gear 505. The top end of the connecting shaft 504 is fixedly connected to a distribution plate 506. The bottom end of the distribution plate 506 is rotatably connected to the upper surface of the support plate 406. Six notches are provided on the distribution plate 506. A packing rack 509 is installed in each notch of the distribution plate 506. A plurality of packing boxes 510 are slidably connected to each packing rack 509; A circular slide rail 507 is fixedly connected to six of the support plates 406 in the same group. The distribution plate 506 is rotatably connected to the slide rail 507. Two groups of second ball bearings 508 are provided on the distribution plate 506. The second ball bearings 508 are in rolling connection with the slide rail 507; The central part of the distribution plate 506 is fixedly connected to an umbrella-shaped rod 511. The top cross-section of the umbrella-shaped rod 511 is an isosceles triangle structure;

[0047] The limiting structure 6 includes a handle 601 and a connecting plate 602. A U-shaped handle 601 is slidably connected to each packing box 510. Two connecting plates 602 are fixedly connected to the bottom end of the handle 601. The connecting plate 602 is slidably connected to the packing box 510. A spring 603 is fixedly connected between the packing box 510 and the connecting plate 602. A clamping rod 604 is fixedly connected to the bottom end of the connecting plate 602. Multiple groups of clamping grooves 605 are provided on the packing rack 509. The clamping rod 604 is engaged with the clamping groove 605. When it is necessary to replace the packing (Raschig rings or Pall rings), first pull the handle 601. The handle 601 drives the connecting plate 602 to move upward, compressing the spring 603, so that the clamping rod 604 disengages from the clamping groove 605. At this time, the packing box 510 can be pulled out from the packing rack 509 for replacement. Start the second-stage energy-saving motor 502. The second-stage energy-saving motor 502 drives the second gear 503 to rotate. The second gear 503 is engaged with the third gear 505, so that the connecting shaft 504 rotates, and then drives the distribution disc 506 to rotate, causing the packing rack 509 and the packing box 510 to rotate accordingly, realizing the rotation of the partition packing, facilitating subsequent operations, rotating the area where the packing needs to be replaced to a position convenient for operation, reducing the replacement difficulty. The umbrella-shaped rod 511 is located in the center of the distribution disc 506. Its special shape can change the flow path of gas and liquid. After the falling absorption liquid hits the umbrella-shaped rod 511, it will be dispersed into finer droplets and splash into the packing areas of each packing rack 509, increasing the gas-liquid contact area, promoting the absorption of carbon dioxide, and improving the absorption efficiency. When the second-stage energy-saving motor 502 drives the distribution disc 506 to rotate, the slide rail 507 and the second ball 508 can effectively disperse the gravity and centrifugal force generated by the rotation of the distribution disc 506, preventing the distribution disc 506 from shaking and shifting, ensuring the stable operation of the packing rack 509 and the packing box 510. At the same time, the second ball 508 is in rolling connection with the slide rail 507, converting the sliding friction during the rotation of the distribution disc 506 into rolling friction, greatly reducing the friction force.

[0048] Specifically, such as Figure 1 , Figure 5 , Figure 9 and Figure 12As shown, the opening and closing structure 7 includes a maintenance door 701 and two driving plates 702 fixedly connected to the maintenance door 701. Two maintenance doors 701 are slidably connected to the tower body 1. Four mounting seats 703 are fixedly connected near the location of each maintenance door 701 on the tower body 1. A second screw rod 704 is rotatably connected to two of the mounting seats 703, and guide rods 706 are fixedly connected to the other two mounting seats 703. One of the driving plates 702 is threadedly connected to the second screw rod 704, and the other driving plate 702 is slidably connected to the guide rod 706. A handwheel 705 is fixedly connected to the bottom end of the second screw rod 704; when it is necessary to perform maintenance or repair on the inside of the tower body 1, rotate the handwheel 705, the handwheel 705 drives the second screw rod 704 to rotate, and the driving plate 702 threadedly connected to the second screw rod 704 will slide along the guide rod 706, so that the two maintenance doors 701 slide downward, exposing the inside of the tower body 1, facilitating operations such as maintenance and component replacement by the staff.

[0049] When the present invention is in use, first, when the absorption tower body 1 is operating, start the first energy-saving motor 303. The first energy-saving motor 303 drives the first gear 304 to rotate. The first gear 304 meshes with the toothed ring 302, thereby driving the liquid distributor 205 to rotate. The first ball 306 is in rolling connection with the toothed ring 302, greatly reducing the friction force when the toothed ring 302 rotates. According to actual requirements, adjust the rotation speed of the first energy-saving motor 303, so as to control the rotation speed of the liquid distributor 205, adjust the spraying angle and the centrifugal force of the liquid spraying, so that the absorption liquid can be more evenly distributed on the tower cross-section. The gas containing carbon dioxide enters the inside of the tower body 1 from the air inlet pipe 203 and flows upward. The absorption liquid enters from the liquid inlet pipe 202 and is evenly sprayed into the tower body 1 through the rotating liquid distributor 205. Under the action of gravity, the absorption liquid flows downward and contacts the upward flowing gas containing carbon dioxide in a countercurrent manner, and an absorption reaction occurs. The carbon dioxide is absorbed by the absorption liquid. After the first absorption, part of the absorption liquid will flow between the two rotating packing structures 5, and the liquid redistributor 206 will redistribute this part of the absorption liquid to make it more evenly distributed to the lower packing area, further improving the absorption efficiency. The absorbed liquid flows into the liquid collection tank 207 at the bottom of the tower body 1, and then is discharged through the drain pipe 204 for subsequent treatment. The gas from which carbon dioxide has been absorbed is discharged from the exhaust port at the top;

[0050] Then, when the packing (Raschig ring or Pall ring) needs to be replaced, first pull the handle 601. The handle 601 drives the connecting plate 602 to move upward, compressing the spring 603, so that the clamping rod 604 disengages from the clamping groove 605. At this time, the packing box 510 can be pulled out from the packing rack 509 for replacement. Then, turn on the second-stage energy-saving motor 502. The second-stage energy-saving motor 502 drives the second gear 503 to rotate. The second gear 503 meshes with the third gear 505, causing the connecting shaft 504 to rotate, and then driving the distribution plate 506 to rotate, making the packing rack 509 and the packing box 510 rotate accordingly, realizing the rotation of the partition packing, facilitating subsequent operations, rotating the area where the packing needs to be replaced to a position convenient for operation, reducing the replacement difficulty. The umbrella-shaped rod 511 is located in the center of the distribution plate 506. Its special shape can change the flow path of gas and liquid. When the falling absorption liquid hits the umbrella-shaped rod 511, it will be dispersed into finer droplets and splash into the packing areas of each packing rack 509, increasing the gas-liquid contact area, promoting the absorption of carbon dioxide, and improving the absorption efficiency. When the second-stage energy-saving motor 502 drives the distribution plate 506 to rotate, the slide rail 507 and the second ball 508 can effectively disperse the gravity and centrifugal force generated by the rotation of the distribution plate 506, preventing the distribution plate 506 from shaking and shifting, ensuring the stable operation of the packing rack 509 and the packing box 510. At the same time, the second ball 508 is in rolling connection with the slide rail 507, converting the sliding friction during the rotation of the distribution plate 506 into rolling friction, greatly reducing the frictional force;

[0051] Secondly, during the construction of the tower body 1, inside the tower body 1, two groups of circumferentially arrayed fixed seats 401 and socket sleeves 402 are respectively and fixedly installed. Each group has six fixed seats 401 and socket sleeves 402, ensuring that they are firmly connected inside the tower body 1, providing a stable foundation for subsequent installation. Fix the swivel base 407 at the bottom end of the support plate 406. Thread the end of the first screw rod 410 with the threaded sleeve 409. Then insert the insertion rod 403 into the socket sleeve 402. After the insertion rod 403 is completely inserted, the pin plate 405 can be completely nailed into the pin hole 404 to complete the installation of the support plate 406. Then, by rotating the first screw rod 410, the inclined support force of the first screw rod 410, the swivel sleeve 408, and the threaded sleeve 409 on the support plate 406 can be adjusted, so that a stable triangular structure is formed between the threaded sleeve 409, the first screw rod 410, the swivel sleeve 408, the support plate 406, and the side wall of the tower body 1, enhancing the stability of the support;

[0052] Finally, when it is necessary to overhaul or maintain the inside of the tower body 1, turn the handwheel 705. The handwheel 705 drives the second screw rod 704 to rotate.
