Description

Technical Field

[0001] This invention relates to the field of waste gas separation technology, specifically a carbon dioxide recycling adsorption device. Background Technology

[0002] In industrial production, carbon dioxide is one of the main gaseous pollutants, and its emission sources are wide-ranging. The common treatment process is adsorption, which uses materials such as activated carbon, molecular sieves, and metal-organic frameworks for adsorption. It has the characteristics of flexible operation and low energy consumption.

[0003] In practical use, existing carbon dioxide adsorption equipment firstly releases heat during the adsorption process, causing the adsorption bed temperature to rise and the adsorption capacity to decrease, which affects the carbon dioxide adsorption efficiency. In addition, when the waste gas enters the adsorption tower, the gas distribution is uneven and the high-speed airflow strongly impacts the adsorption bed, which not only reduces the contact efficiency between the adsorbent and the gas, but also easily causes the adsorption bed to pulverize, shortening the adsorbent's service life. Therefore, there is an urgent need to develop a carbon dioxide circulating adsorption equipment. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this invention, when the temperature between the second adsorption bed and the third adsorption bed rises, the second gear at the top of the rotating shaft in the temperature control mechanism drives the outer ring body to rotate, and the lifting arc strip on the inner wall of the outer ring body pushes the third adsorption bed to slide upward, increasing the bed spacing and promoting air circulation for cooling. At the same time, the outer ring body drives the rotary spray arm to rotate through gear transmission, spraying the second adsorption bed to further cool it.

[0020] 2. In this invention, driven by a conical drive wheel assembly, the top and side of the diverter are respectively provided with side holes and top holes. With the intermittent triggering structure of the trigger block and the rotating frame, the gas-gathering impeller gathers the exhaust gas to the center of the ventilation pipe when it rotates. With the alternating opening and closing of the top hole and side hole of the diverter, the impact velocity of the exhaust gas can be reduced, thereby reducing the pulverization rate of the adsorption bed and making the exhaust gas contact the first adsorption bed more evenly.

[0021] 3. In this invention, by setting up a second adsorption bed that is thinner at the bottom and a third adsorption bed that is thicker at the top, the concentration of carbon dioxide in the waste gas gradually decreases from bottom to top during the adsorption process. The lower thin bed can quickly adsorb high concentrations of carbon dioxide, while the upper thick bed further adsorbs low concentrations of carbon dioxide, thereby improving the adsorption efficiency.

[0049] Example 2:

[0050] Please see Figures 4 to 5 The present invention provides a technical solution:

[0051] The gas equalization mechanism 7 includes a vent pipe 701, which is positioned higher than the air inlet pipe 401. A gas-gathering impeller 702 is rotatably mounted at the bottom of the vent pipe 701, and a first toothed ring 703 is fixedly connected to the top of the gas-gathering impeller 702. The first toothed ring 703 meshes with the first gear 606.

[0052] A mounting bracket 704 is fixedly connected to the middle of the vent pipe 701.

On one side of the 4 end face, a rotating frame 708 is slidably connected to the ring 706. The rotating frame 708 is rotatably connected to the diverter 705, and its bottom abuts against one side of the spring 707. A lever 709 is fixedly connected to the side wall of the rotating frame 708. The lever 709 abuts against the trigger block 605.

[0054] The drive mechanism 6 includes a drive motor 601. The output end of the drive motor 601 is rotatably connected to a rotating shaft 602. The bottom and top of the rotating shaft 602 are respectively connected to a conical drive wheel set 603 and a second gear 607. The side of the conical drive wheel set 603 away from the rotating shaft 602 is connected to a rotating shaft 604. The top of the rotating shaft 604 is fixedly connected to a trigger block 605 off its axis. The bottom of the rotating shaft 604 is fixedly connected to a first gear 606.

[0055] In this embodiment, the rotation direction of the gas-gathering impeller 702 is the same as the rotation direction of the rotating frame 708;

[0056] In this embodiment, the circular cap 715 applies pressure to the diverter 705 during its descent, thereby increasing the flow rate of the waste gas flowing through the side hole 710 and facilitating its uniform flow out of the side hole 710.

[0057] In this embodiment, the exhaust gas after being processed by the gas equalization mechanism 7 comes into full contact with the first adsorption bed 402 in a more uniform state, which not only increases the contact area but also reduces the impact of the gas on the first adsorption bed 402, effectively reducing the pulverization phenomenon of the first adsorption bed 402 caused by gas impact.

[0058] Example 3:

[0059] Please see Figures 6 to 8 The present invention provides a technical solution:

[0060] The temperature control mechanism 8 includes an outer ring body 801, which is rotatably connected to the top of the inner tower 3. A second toothed ring 802 is fixedly connected to the top of the outer ring body 801, and the outer surface of the second toothed ring 802 meshes with the second gear 607.

[0063] A second gear 607 is fixedly connected to the bottom of the rotating shaft 604;

[0064] In this embodiment, the third toothed ring 806 on the inner wall of the outer ring body 801 meshes with the third gear 807, driving the third gear 807 to rotate. The third gear 807 is driven by the pulley group 808, causing the rotary spray arm 506 to rotate at the top of the water supply pipe 505 and spray the second adsorption bed 403.

[0065] The method of use and advantages of this invention: The working process of this carbon dioxide circulating adsorption device is as follows:

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown:

[0067] S1: When adsorption begins, the drive motor 601 starts running, driving the rotating shaft 602 to rotate. Simultaneously, the conical drive wheel assembly 603 at the bottom rotates, which in turn drives the rotating shaft 604 to rotate. The trigger block 605 at the top of the rotating shaft 604 also begins to rotate. The second gear 607 at the top of the rotating shaft 602 meshes with the second gear ring 802 in the temperature control mechanism 8, providing power to the temperature control mechanism 8. The control box 501 starts the pump, conveying the liquid through the main pipe 502 to the spray pipe 503 located above the first adsorption bed 402 and the third adsorption bed 404, spraying the first adsorption bed 402 and the third adsorption bed 404. Simultaneously, the sprayed wastewater enters the water storage tank 201 through the through hole 302 and the filter plate 202. The water pump 504 in the water storage tank 201 then... Water is transported to the rotary spray arm 506 via the water supply pipe 505. Driven by the third gear 807, the rotary spray arm 506 rotates to spray and cool the area between the second adsorption bed 403 and the third adsorption bed 404. The liquid generated by the spraying is guided by the water guide platform 301 at the bottom of the inner tower 3 and flows into the water storage tank 201 at the bottom of the outer tower 2 through the through hole 302. The filter plate 202 at the inlet of the water storage tank 201 filters the liquid to prevent impurities from clogging the pipes, so as to facilitate subsequent recycling. The gas after being adsorbed by the first adsorption bed 402, the second adsorption bed 403 and the third adsorption bed 404 is discharged through the exhaust pipe 405 at the top of the inner tower 3. The blower 406 transports the gas to the filter box 407, which further filters the gas to ensure that the discharged gas meets the emission standards.

[0068] S2: Carbon dioxide-containing waste gas enters the inner tower 3 through the inlet pipe 401. Since the vent pipe 701 is higher than the inlet pipe 401, most of the waste gas will enter the vent pipe 701. In the vent pipe 701, the drive mechanism 6 drives the gas-gathering impeller 702 to rotate through the conical drive wheel set 603. The gas-gathering impeller 702 gathers the waste gas, and the waste gas flows upward into the vent pipe 701. At the same time, during the rotation of the rotating shaft 604, the trigger block 605 intermittently abuts against the lever 709 on the side wall of the rotating frame 708. When the trigger block 605 pushes the lever 709, the rotating frame 708 overcomes the elastic force of the spring 707 and rotates slightly on the ring 706. The rotating frame 708 drives the synchronous frame 713 and the lifting arc bar 714. Rotating, the lifting arc bar 714 pushes the first mounting block 716 on the side of the cover 715, causing the cover 715 to slide downward inside the diverter 705, blocking the top hole 712. At this time, the rotating frame 708 opens the side hole 710, allowing the exhaust gas in the diverter 705 to flow through the side hole 710. When the trigger block 605 separates from the lever 709, the spring 707 resets, the rotating frame 708 returns to its original position, the lifting arc bar 714 pushes the first mounting block 716 on the side of the cover 715, causing the cover 715 to slide upward inside the diverter 705, opening the top hole 712 and simultaneously closing the side hole 710, allowing the exhaust gas to flow through the top hole 712, achieving alternating diversion of exhaust gas and further evenly distributing the gas.

[0069] S3: After the exhaust gas comes into full contact with the first adsorption bed 402, it continues to flow upward and comes into contact with the second adsorption bed 403 for further carbon dioxide adsorption. During the adsorption process, an exothermic phenomenon occurs, which causes the adsorption capacity of the adsorption bed to decrease. When the temperature between the second adsorption bed 403 and the third adsorption bed 404 rises, the second gear 607 at the top of the rotating shaft 602 drives the outer ring 801 in the temperature control mechanism 8 to rotate. The lifting arc strip 805 on the inner wall of the outer ring 801 comes into contact with the second mounting block 804 on the outer surface of the third adsorption bed 404. As the outer ring 801 rotates, the lifting arc strip 805 pushes the second mounting block 804, causing the third adsorption bed 404 to slide upward in the notch 803 of the inner tower 3, raising the third adsorption bed 404, increasing the distance between it and the second adsorption bed 403, promoting air circulation, and performing cooling treatment.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
