Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 2 、 Figure 3 and Figure 4 , an embodiment provided by the present invention:

[0025] It includes an air pump 1. One side of the air pump 1 is connected to a compressor 2 through a pipeline. The air outlet of the compressor 2 is connected to a condenser 3 through a pipeline. One side of the condenser 3 is connected to an impurity removal component, a first heat exchange tube 4. The first heat exchange tube 4 is arranged on the outer surface of the condenser 3. The bottom end of the first heat exchange tube 4 is connected to an absorption heat pump 5. The exhaust port of the absorption heat pump 5 is connected to a three-way pipe 6 through a pipeline. The air inlet of the absorption heat pump 5 is provided with a second heat exchange tube 7. The bottom end of the second heat exchange tube 7 is connected to a regeneration tower 8;

[0026] When using the automatic collection and separation system for carbon dioxide mixed gas, the compressor 2 is used to lift the low-pressure carbon dioxide mixed gas in the air pump 1 to a high-pressure gas. Then, the high-pressure carbon dioxide mixed gas is cooled into a liquid by the condenser 3. Then, the liquid completes the extraction of carbon dioxide through the impurity removal component. During the operation of the condenser 3, heat is released. The absorption heat pump 5 absorbs heat through the first heat exchange tube 4, and then the absorption heat pump 5 discharges the heat into the three-way pipe 6 for use. The heat generated by the regeneration tower 8 is absorbed into the absorption heat pump 5 through the second heat exchange tube 7, improving the energy utilization rate.

[0027] Furthermore, the outer surface of the three-way pipe 6 is rotatably connected to a reversing valve 11. One side of the three-way pipe 6 is threadedly connected to a first conduit 12. One side of the three-way pipe 6 is threadedly connected to a second conduit 13. And the second conduit 13 is connected to one side of the regeneration tower 8. The bottom of the reversing valve 11 is in a semi-arc block shape, and the reversing valve 11 is adapted to the first conduit 12 and the second conduit 13;

[0028] By rotating the reversing valve 11, the exhaust port of the absorption heat pump 5 is opened and away from the first conduit 12 and the second conduit 13, and the heat is transferred through the first conduit 12 and the second conduit 13 to other working areas and the regeneration tower 8 for use respectively. When the regeneration tower 8 has sufficient heat, rotate the reversing valve 11 to block the inlet of the second conduit 13 and reduce energy waste.

[0029] Please refer to Figure 1 、 Figure 2 and Figure 5 , an embodiment provided by the present utility model:

[0030] The impurity removal assembly includes an adsorption tower 9 and a drying tower 10. The adsorption tower 9 is connected to one side of the condenser 3 through a pipeline. The drying tower 10 is connected to one side of the adsorption tower 9 through a pipeline, and the adsorption tower 9 is connected to the outer surface of the regeneration tower 8 through a pipeline. A liquid extraction pump 14 is connected to one side of the adsorption tower 9 through a pipeline, and the outlet of the liquid extraction pump 14 is connected to one side of the drying tower 10 through a pipeline;

[0031] When the mixed carbon dioxide liquid enters the adsorption tower 9, the adsorption tower 9 uses the adsorption effect of the adsorbent to remove impurities from the mixed carbon dioxide liquid, so that the liquid contains carbon dioxide and water. Then, the liquid extraction pump 14 is started, and then the liquid extraction pump 14 pumps the carbon dioxide liquid in the adsorption tower 9 into the drying tower 10 through the pipeline. The drying tower 10 dries the carbon dioxide liquid by using high temperature, thereby removing moisture and completing the extraction of carbon dioxide. The remaining mixed liquid is added to the regeneration tower 8, and the regeneration tower 8 resolves the absorbed or adsorbed substances for reuse.

[0032] Further, a first delivery pipe 15 is connected to one side of the drying tower 10, and a collection rack is connected to the bottom end of the first delivery pipe 15. A second delivery pipe 16 is connected to the top of the regeneration tower 8, and a collection cylinder is connected to the bottom end of the second delivery pipe 16;

[0033] The collected carbon dioxide is collected into the collection rack through the first delivery pipe 15 to complete the collection of carbon dioxide, and other gases are recovered into the collection cylinder through the second delivery pipe 16 for reuse.

[0034] Working principle: During the process of collecting carbon dioxide, the condenser 3 is used to convert the carbon dioxide mixed gas into a liquid. The liquid completes the separation and collection of carbon dioxide through the impurity removal assembly. During the operation of the condenser 3, heat is released. The absorption heat pump 5 is used to absorb heat through the first heat exchange pipe 4, and the heat is used for the regeneration tower 8 and in daily life through the three-way pipe 6. The heat generated by the regeneration tower 8 is inhaled into the absorption heat pump 5 through the second heat exchange pipe 7, improving the energy utilization rate and saving energy. In addition, the remaining mixed liquid is added to the regeneration tower 8, and the absorbed or adsorbed substances are resolved for easy reuse.
