[0002] Since the 20th century, climate warming has become the most prominent global environmental problem in the world today. It is a global consensus that carbon dioxide emissions are the main cause of rising global temperatures. According to data from the International Energy Agency, in 2007, my country's carbon emissions exceeded those of the United States for the first time. In 2020, my country's carbon emissions accounted for 30.7% of global carbon emissions, ranking first in the world, and the total amount of carbon emissions is still increasing rapidly.

[0011] Furthermore, the bell-shaped shroud is hollow inside, has a bell-shaped structure, a flat bottom and ventilation openings around the perimeter; the top part has an opening that can be detachably connected to the carbon dioxide capture pipe.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-11 An experimental apparatus for capturing carbon dioxide includes: a carbon dioxide storage bottle 1, a carbon dioxide capturing section, and a bell-shaped jar 3, wherein the carbon dioxide storage bottle 1 and the bell-shaped jar 3 are connected through the carbon dioxide capturing section.

[0029] In this embodiment, the carbon dioxide capture part includes several carbon dioxide capture tubes 4; the several carbon dioxide capture tubes 4 are detachably connected end to end to form a columnar structure; the carbon dioxide capture tube 4 is cylindrical in shape, the head end is detachably connected to the carbon dioxide storage bottle 1, and a baffle is provided inside the head end, with several small holes opened on the baffle; the tail end is an open structure and is detachably connected to the bell-shaped cover 3.

[0030] In this embodiment, the carbon dioxide storage bottle 1 is conical in shape, and its opening is connected to the carbon dioxide collection part; the bell-shaped cover 3 is hollow inside, has a bell-shaped structure, a flat bottom and ventilation openings around the perimeter; the top part has an opening that can be detachably connected to the carbon dioxide collection tube 4.

[0031] In this embodiment, the outer wall of the head end of the carbon dioxide collection tube 4 is provided with several protrusions, and the inner wall of the tail end of the carbon dioxide collection tube 4 is provided with an annular groove. The insertion of several carbon dioxide collection tubes 4 is achieved by the cooperation of the protrusions and the annular groove. The inner wall of the opening of the carbon dioxide storage bottle 1 is also provided with an annular groove, so that the carbon dioxide storage bottle 1 can be inserted into the head end of the carbon dioxide collection tube 4. The outer wall of the opening of the bell-shaped cover 3 is provided with several protrusions, so that the opening of the bell-shaped cover 3 can be inserted into the tail end of the carbon dioxide collection tube 4, and a baffle is provided inside the opening of the bell-shaped cover 3, with several small holes.

[0032] In this embodiment, the carbon dioxide storage bottle 1 can be a conical flask of different specifications, which can store a certain amount of greenhouse gas carbon dioxide. The carbon dioxide can be collected in the laboratory or purchased commercially. When in use, carbon capture materials, such as lime or membrane packing, are placed into the carbon dioxide capture tube 4 as needed. The number of sections of the carbon dioxide capture tube 4 can be increased or decreased depending on the amount of carbon dioxide captured. A sponge pad 7 is installed at the head end of the carbon dioxide capture tube 4 connected to the carbon dioxide storage bottle 1, which can reduce the flow rate of the experimental gas and make the experimental results more accurate. When in use, a detection candle is placed inside the bell-shaped shroud 3. When the experimental gas enters the bell-shaped shroud 3 through the carbon dioxide capture part, the density will cause the air to be discharged from the bottom vent due to the density, thereby avoiding the influence of oxygen in the air on the experimental results and greatly increasing the accuracy of the experimental results.

[0033] Example 2:

[0034] Please see Figure 1-11 According to Example 1, since the reaction between carbon dioxide and calcium lime generates heat during the experiment using the carbon dioxide capture apparatus, which affects the experimental results, the following design was implemented:

[0035] A spiral cooling pipe 5 is detachably wound around the carbon dioxide capture part, and several annular protective covers 2 are detachably installed on the carbon dioxide capture part to cover the spiral cooling pipe 5.

[0036] In this embodiment, the spiral cooling tube 5 is formed by spirally winding a hollow tubular structure, and the inner diameter of the spiral is equal to the outer diameter of the carbon dioxide collection tube 4. In order to ensure the shape of the spiral cooling tube 5, a spring is fixedly installed on the tube wall of the spiral cooling tube 5. Through the toughness and recoverability of the spring, the spiral cooling tube 5 can maintain its spiral shape well. Moreover, the spiral cooling tube 5 can be stretched according to the number of sections of the carbon dioxide collection tube 4, so that the spiral cooling tube 5 can cover each section of the carbon dioxide collection tube 4 well, thereby cooling the carbon dioxide collection tube 4 and increasing the accuracy of the experimental results.

When in use, coolant is injected through the opening, and the piston 51 is closed to cool the carbon dioxide collection pipe 4. The spiral cooling pipe 5 can also be cooled by using an external cooling machine. By connecting the two ends of the spiral cooling pipe 5 to an existing circulating cooling machine, the coolant circulates in the spiral cooling pipe 5 to cool the carbon dioxide collection pipe 4.

[0038] In this embodiment, the spiral cooling pipe 5 is detachably equipped with fixing straps 6 at both ends. One end of the fixing strap 6 has a hook side with Velcro on the outer side and the other end has a hook side with Velcro on the inner side. A silicone sleeve is fixed on the fixing strap 6 to cover one end of the spiral cooling pipe 5. To further prevent the silicone sleeve from coming off the spiral cooling pipe 5, it can be fixed by wrapping it with cable ties or wire. In order to make the fixing strap 6 stably wrapped around the outer wall of the carbon dioxide collection pipe 4, a silicone layer is provided on the inner side of the fixing strap 6 to increase the friction with the carbon dioxide collection pipe 4. The two ends of the spiral cooling pipe 5 are fixed to the upper and lower outer walls of the carbon dioxide collection part by the cooperation of the hook side and the hook side of Velcro.

[0039] In this embodiment, for the safety of the spiral cooling pipe 5, an annular protective cover 2 is fitted around the spiral cooling pipe 5; the annular protective cover 2 includes two arc-shaped plates, one side of the two arc-shaped plates is hinged together, and the other side is magnetically closed by a magnet 21; the magnets 21 on the other side of the two arc-shaped plates are opposite poles attracting each other; so that the annular protective cover 2 can be flexibly disassembled and installed according to the number of sections of the carbon dioxide capture pipe 4.

[0040] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
