At room temperature and pressure, it is a colorless and odorless gas, while its aqueous solution has a slightly acidic taste. It is also a common greenhouse gas. By recycling and reusing carbon dioxide, the concentration of carbon dioxide in the atmosphere can be significantly reduced, thereby slowing down the rate of global warming.

[0003] Chinese Patent Publication No. CN221182071U discloses a carbon dioxide recovery and utilization device. This utility model provides a carbon dioxide recovery and utilization device that solves the technical problem of excessive dust content in the gas during the carbon dioxide recovery process in existing technologies. The carbon dioxide recovery and utilization device includes a filter and a fan. The fan supplies the gas filtered by the filter into the dryer. By setting up the filter, dust contained in the gas can be filtered out, thereby reducing the dust content in the gas stored in the dryer.

[0004] A carbon dioxide recovery and utilization device disclosed in the patent documents can filter and dry the recovered carbon dioxide to reduce impurities. Since the filtration and drying structure is located inside the device, the filtration and drying effect of the filtration and drying structure will be affected as the usage time increases, and it needs to be replaced. However, the device is not easy to disassemble and assemble, making replacement quite troublesome.

[0005] Therefore, a closed carbon dioxide recovery device is being developed to address the above problems. Utility Model Content

The connecting block 5 is installed on one side of the top of the recovery tower 1, the connecting shaft 6 is installed on the top of the connecting block 5, the positioning plate 7 is installed on the other side of the top of the recovery tower 1, the rotating cylinder 18 is installed on the top of the recovery tower 1, the rotating block 19 is installed on the bottom side of the rotating cylinder 18, and the rotating block 19 is rotatably connected to the connecting shaft 6. The base 2 is installed at the bottom of the recovery tower 1, an air inlet pipe 3 is installed through one side of the recovery tower 1, a sealing gasket 4 is installed at the top of the recovery tower 1, and an exhaust pipe 20 is installed through the top of the rotating cylinder 18.

[0027] The recovery tower 1 provides space for carbon dioxide recovery. As the carbon dioxide passes through the recovery tower 1, it is filtered and dehumidified by the internal packing material. To facilitate the replacement of the internal packing material, a rotating cylinder 18 is installed at the top of the recovery tower 1 via a connecting assembly. Rotating the cylinder 18 opens the top of the recovery tower 1, allowing workers to easily remove the internal packing material. The rotating cylinder 18 is installed by a through-hole connection between a rotating block 19 on one side and a connecting shaft 6. The connecting block 5 provides the mounting position for the connecting shaft 6. After the rotating cylinder 18 is connected via the rotating block 19, it can rotate at the top of the recovery tower 1. The rotating cylinder 18 is fixed to the recovery tower 1 by connecting the upper and lower corresponding positioning plates 7. The rotating cylinder 18 is also equipped with a positioning plate 7 on one side. When it is necessary to open the top of the recovery tower 1, the bolts used to fix the positioning plate 7 are removed, so that the rotating cylinder 18 can rotate under the action of the rotating block 19, so that the top of the recovery tower 1 is opened, making it easier to remove the packing inside the recovery tower 1 and making the replacement of the internal packing more convenient and simple. The sealing gasket 4 is used to increase the sealing between them. The base 2 is used to support the bottom of the recovery tower 1. The air inlet pipe 3 provides space for carbon dioxide to enter the recovery tower 1. The exhaust pipe 20 is used to discharge the filtered carbon dioxide.

[0028] like Figures 1-4 As shown, this utility model embodiment provides a closed carbon dioxide recovery device;

[0029] Inside the recovery tower 1, there is a support ring 8. At the bottom of the support ring 8, there is a connecting shell 9. At the bottom of the connecting shell 9, there is a diffuser shell 11. At the bottom of the diffuser shell 11, there is a connecting pipe 12, which is connected to the air inlet pipe 3.

At the top of the installation shell 13, there is a protective net 16. At the top of the protective net 16, there are pull-out handles 17 symmetrically installed.

[0030] The support ring 8 is used to support the mounting shell 13. The filter packing 14 and the moisture-absorbing packing 15 are used to filter impurities and moisture in the carbon dioxide. The carbon dioxide is transferred to the diffuser shell 11 through the connecting pipe 12. The diffuser shell 11 allows the carbon dioxide to enter the interior of the connecting shell 9. The connecting shell 9 provides a position for the opening of the venting hole 10. The carbon dioxide inside the connecting shell 9 enters the packing layer inside the mounting shell 13 evenly through the venting hole 10, so that the packing can contact the carbon dioxide to the maximum extent, making the packing more efficient and the filtration effect of carbon dioxide better. The protective net 16 is installed by bolts and provides a position for the installation of the pull handle 17. The pull handle 17 makes it easy to pull out the internal packing.
