Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide production, in particular to a separation device for carbon dioxide production. Background Art

[0002] Flue gas emissions produced during the combustion process refer to waste gases or smoke that are released into the atmosphere by combining carbon with oxygen to form carbon dioxide. These released carbon dioxide will gradually accumulate in the atmosphere, leading to the greenhouse effect, which in turn causes the problem of rising global temperatures. In order to cope with the impact of such carbon dioxide emissions on the environment, the international community has generally paid attention and taken various measures. One of the important measures is to use a separation device to separate carbon dioxide from the exhaust gas to reduce its negative impact on the atmospheric environment;

[0003] After searching, a Chinese patent with the announcement number of CN220294404U discloses a carbon dioxide separation device for flue gas emission. The patent records that by setting the dust filter box and the filter plate in sliding connection, the filter plate can be easily disassembled, and by setting the motor 1, the screw rod, and the guide rod, the cleaning brush can be used to clean the filter plate to prevent clogging and improve the quality of filtration. By setting the motor 2, the stirring shaft, and the stirring blade, the carbon dioxide and the absorbent in the absorption box can be more evenly integrated, and the carbon dioxide and other gases can be effectively separated. Then, by setting the drainage pipe, the separation box, the isolation plate, the electric heating wire, the exhaust pipe, and the air pump, the carbon dioxide can be separated from the absorbent and collected in the gas storage tank. Technical solution;

[0004] In this solution, although the filter plate is convenient for cleaning during filtration, the characteristic of the fusion agent to absorb carbon dioxide is utilized during the stirring process. However, the stirring is only performed by a simple stirring blade, which results in slow or incomplete absorption of the fusion agent, causing some carbon dioxide to still be discharged. At the same time, some residues of the fusion agent will remain on the inner wall of the box after the fusion is completed, which is inconvenient to clean and affects the next use. In order to solve this technical problem, the utility model proposes a separation device for carbon dioxide production. Summary of the invention

In the mixing box 3, a solvent that can absorb carbon dioxide (such as ethylenediamine MEA and dimethylamine MDEA) is injected into the mixing box 3 through the dosing pipe 13. After the motor 15 is started, the rotating shaft 16 begins to rotate, driving the stirring rods 18 on both sides of the connecting ring 17 to stir the solvent and the gas to promote the absorption rate of carbon dioxide. The movement of the stirring rods 18 will also cause the rotating plate 26 on the rotating column 23 to rotate, further improving the working efficiency. The gas that cannot be absorbed by the solvent is discharged through the exhaust pipe 14.

[0025] Embodiment 2: The difference between this embodiment and embodiment 1 is that an air pump 5 is provided on the outer wall of the filter box 2, and an air inlet pipe 6 is fixedly connected to the output end of the air pump 5, and the air inlet pipe 6 penetrates the air pump 5 and extends to the inside of the filter box 2, a pair of filter plates 8 are slidably connected to the inside of the filter box 2, and sliders 9 are fixedly connected to both sides of the filter plate 8, a slide groove 7 is provided inside the filter box 2, and the slider 9 is slidably connected to the inside of the slide groove 7, a sealing gasket 10 is provided on the top of the filter plate 8, a ventilation pipe 12 is fixedly connected to the outer wall of the filter box 2, and a valve 11 is provided at one end of the ventilation pipe 12, and the other end of the ventilation pipe 12 penetrates the mixing box 3 and extends to the inside of the mixing box 3, the outer wall of the stirring rod 18 is a left and right scraper assembly, the scraper assembly includes a scraper plate 20, the outer wall of the stirring rod 18 is fixedly connected to a connecting plate 19, a slide groove 21 is provided inside the connecting plate 19, and the scraper A slide plate 22 is fixedly connected to the inner wall of the plate 20, and the slide plate 22 corresponds to the second slide groove 21, and the slide plate 22 is slidably connected to the inside of the second slide groove 21, and a water pipe 27 is fixedly connected to the inside of the mixing box 3, the water pipe 27 passes through the separation box 4 and extends to the inside of the separation box 4, a number of heating rods 28 are fixedly connected to the inside of the separation box 4, and an outlet pipe 230 is fixedly connected to the top of the separation box 4, and a drain pipe 29 is arranged inside the lower part of the separation box 4. The gas enters the filter box 2 through the air pump, and is filtered through the filter plate 8 to remove impurities. The gas is then sent to the stirring mechanism through the ventilation pipe 12 for mixing and absorption. After the gas is finished, the impurities remaining on the inner wall of the mixing box 3 are cleaned by the scraper plate 20, and the fused gas flows into the inside of the separation box 4 through the water pipe 27, is heated and separated by the heating rod 28, and the carbon dioxide is discharged and collected through the outlet pipe 230.

[0026] During operation, the gas containing carbon dioxide is sent into the interior of the filter box 2 through the air inlet pipe 6 under the start of the air pump 5, and the particles in the gas are filtered through the filter plate 8. After multiple uses, the filter plate 8 is pulled up and extracted from the interior of the filter box 2 through the slider 9 for easy cleaning. At this time, the valve 11 is opened, and the filtered gas is discharged into the interior of the mixing box 3 through the ventilation pipe 12. At this time, the solvent (ethylenediamine MEA, dimethylamine MDEA) that can absorb carbon dioxide is poured into the interior of the mixing box 3 through the dosing pipe 13, and the motor 15 is started again. Under the action of the motor 15, the rotating shaft 16 will be driven to rotate. When the rotating shaft 16 rotates, the stirring rods 18 on both sides of the connecting ring 17 will be driven to stir. At this time, the solvent and the gas are in contact. In order to speed up the absorption rate, when the stirring rod 18 rotates, the impact of the solvent will drive the rotating plate 26 on the rotating column 23 to rotate, thereby improving the working efficiency and preventing fusion. The gas is discharged through the exhaust pipe 14. When the solvent completely absorbs carbon dioxide, the solvent will flow into the separation box 4 through the water pipe 27 by opening the valve on the water pipe 27. At this time, the heating rod 28 inside the separation box 4 is started. Under the continuous heating of the heating rod 28, the carbon dioxide will be separated from the solvent. By starting the air pump on the top of the separation box 4, the carbon dioxide inside the separation box 4 will be discharged through the outlet pipe 2 30 and collected by the staff. After use, the solvent is discharged through the drain pipe 29. After the reaction inside the mixing box 3, it needs to be cleaned. After adding clean water, the connecting plate 19 on the stirring rod 18 will be driven to rotate by starting the motor 15. At this time, the scraper plate 20 on the connecting plate 19 will fit the inner wall of the mixing box 3 for scraping and washing. After the cleaning is completed, the scraper plate 20 is pulled up and the scraper plate 20 is drawn out of the chute 21 through the slide plate 22. With their cooperation, the work efficiency is greatly improved.
