[0031] The present invention will be further described below with reference to the accompanying drawings. It should be emphasized that the embodiments described in the present invention are illustrative and not limiting. Therefore, the present invention is not limited to the embodiments described in the specific embodiments. Any other embodiments derived by those skilled in the art based on the technical solution of the present invention are also within the scope of protection of the present invention.

[0032] like Figure 1-5 As shown, a carbon dioxide absorption device suitable for small, enclosed spaces includes: a reagent tank 4, a top cover 1 disposed above the reagent tank 4, and an electrical box 5 disposed below the reagent tank 4. The bottom plate 10 of the electrical box 5 has several through holes communicating with the outside environment, allowing outside gas to enter the device. The electrical box 5 is equipped with an electrical connector connected to an external power supply, enabling an internal fan 11 to absorb carbon dioxide-containing gas from the outside environment and transport it to the reagent tank 4. A gas distribution plate 15 with several through holes is disposed at the bottom of the reagent tank 4 to evenly distribute the airflow. A low-resistance carbon dioxide absorbent (such as a filter containing lithium hydroxide) is placed on the gas distribution plate 15. Gas from the electrical box 5 passes through the low-resistance carbon dioxide absorbent, where the carbon dioxide is absorbed, and the remaining gas is discharged from the outlet of the top cover 1.

[0033] Example 1

[0034] The electrical box 5 has an opening on the front for installing a switch 6; a hanging bracket 3 is fixed to the outer wall by welding. A certain number of fixing plates 9 are vertically welded to the inner side wall of the electrical box 5. The lower end of the fixing plate 9 is used for mounting and fixing the base plate 10, and the upper end is used for mounting the fan 11 mounting bracket 14.

[0035] The base plate 10 has a circular boss structure with several through holes machined in the middle to communicate with the outside, for air intake of the device. The fan 11 is a small-power turbine fan, which is fixed in a horizontal installation manner, so that the turbine shaft of the fan 11 is set vertically and the air outlet of the fan 11 is set horizontally. This makes the installation area of ​​the fan 11 more compact, the space utilization rate is higher, and the volume of the electrical box 4 is reduced, which meets the requirements of the device for use in a confined space.

[0036] As an example, an air outlet elbow 13 is welded onto the mounting bracket 14. The size of the air outlet elbow 13 matches the size of the air outlet of the fan 11, which is used to guide the air outlet of the fan 11 smoothly into the reagent tank 4, reduce the generation of eddies during the flow process, and reduce energy consumption.

[0037] As an example, a silencer 12 is installed at the air inlet of the fan 11, and the silencer 12 is fastened to the air inlet with screws. The silencer 12 has a perforated plate structure, and the space between its inner and outer plates is filled with sound-absorbing material to reduce the noise of the fan 11.

[0038] As an example, the device also includes a latch 7 and a hinge 2, with the outer wall of the top cover 1 connected to the medicine box 4 using the hinge 2, and the outer wall of the top cover 1 connected to the medicine box 4 using the latch 7.

[0039] As an example, there are several air vents on the top cover 1, which are evenly distributed on the side wall of the top cover 1.

[0040] Example 2

[0041] The device has an overall cylindrical structure. Specifically, the electrical box 5 is cylindrical, and the medicine box 4 is cylindrical with openings at both ends; both are made of 1.5mm thick stainless steel. The suspension bracket 3 is saddle-shaped, with through holes of specified dimensions machined on it, and is welded to the outer wall of the medicine box 4.

[0042] As an example, an annular mounting base is welded to the inner wall of the medicine tank 4. As a connecting structure, the annular mounting base has a certain number of through holes. The medicine tank 4 can be fixed together with the electrical box 5 and the gas distribution plate 15 by screws through the annular mounting base.

[0043] As an example, the electrical box 5 has through holes of a specified size on its wall for mounting and fixing the switch 6; the wall also has through holes of a specified size for mounting the electrical connector 8. A hanging bracket 3 is also welded to the outer wall of the electrical box 5. This hanging bracket 3 is aligned with the outer wall of the medicine box 4, allowing the carbon dioxide absorption device, suitable for small enclosed spaces, to be suspended and fixed within the enclosed space using bolts, hooks, etc., thus meeting the requirements for using the device in confined spaces.

[0044] As an example, four "L"-shaped fixing plates 9 are welded to one side of the electrical box 5 near the boss structure of the base plate 10. Bolt holes are machined on the fixing plates 9. The bottom of the "L"-shaped fixing plates 9 is used for the installation and fixing of the base plate 10. The top of the "L"-shaped fixing plates 9 is equipped with a fixing frame 14 with an overall circular structure, which is used for the installation and fixing of the fan 11.

[0045] As an example, the gas distribution plate 15 is a circular sheet metal structure with a certain number of through holes machined in the middle for uniformly distributing airflow.

[0046] As an example, the base plate 10 is made of stainless steel with a thickness of 1 mm.

[0047] As an example, the top cover 1 is made of 1mm thick stainless steel, and a certain number of elongated air outlets are stamped on the side of the top cover 1 for the discharge of purified air.

[0048] Working principle

[0049] When using this device, firstly, the device is suspended and fixed to the side wall of the enclosed space, and the electrical connector 8 is connected to the external power supply.

[0050] Then, open the latch 7, lift the top cover 1, put the low-resistance carbon dioxide absorbent into the reagent tank 4, close the top cover 1 and lock the latch 7.

[0051] Finally, press switch 6 to start the carbon dioxide absorption device and begin the carbon dioxide removal process; after the process is complete, press switch 6 again to stop the carbon dioxide absorption device.

[0052] Experimental results:

[0053] To verify the performance of the device, it was suspended and fixed at a height of 4m. 3The side wall of the sealed test chamber was inspected, and a filter containing lithium hydroxide was placed inside the reagent tank. The carbon dioxide analyzer inside the sealed chamber was turned on. After the analyzer displayed a normal reading, the test chamber door was closed, and carbon dioxide gas was introduced into the test chamber at a flow rate of 1.35 L / min. When the carbon dioxide concentration in the test chamber reached 0.5%, the carbon dioxide absorption device of this invention was activated, and test data was recorded. As the device continued to operate, the carbon dioxide concentration in the test chamber gradually decreased to its lowest point, and then began to rise slowly. After 14 hours, the carbon dioxide concentration in the test chamber reached 0.5% again, and the test ended. Throughout the test, the device power was maintained below 15W, and the test results met the design requirements, achieving a good carbon dioxide control effect.

[0054] In summary, the above are embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
