Description

Technical Field

[0001] The utility model relates to the field of recovery systems, and more specifically to a carbon dioxide gas phase recovery system. Background Art

[0002] Carbon dioxide can generally be produced by calcining limestone at high temperature or by reacting limestone with dilute hydrochloric acid. It is mainly used for refrigerating perishable foods, as a refrigerant, making carbonated soft drinks, and as a solvent for homogeneous reactions.

[0003] Currently, there is no system technology that can utilize gaseous carbon dioxide. Excessive emissions will affect the environment and increase costs. Therefore, a system is needed to reduce carbon dioxide loss, save energy and reduce emissions, and achieve partial economic benefits. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a carbon dioxide gas phase recovery system, which can solve the problem of reducing carbon dioxide loss, saving energy and reducing emissions, and achieving partial economic benefits.

[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically a carbon dioxide gas phase recovery system comprises a liquid CO2 storage tank 1, the liquid CO2 storage tank 1 is fixedly connected to a liquid CO2 storage tank 2, the top ends of the output ends of the liquid CO2 storage tank 1 and the liquid CO2 storage tank 2 are both fixedly connected to a compressor, the output ends of the compressor are fixedly connected to a refrigerator, the output end of the refrigerator is fixedly connected to the liquid CO2 storage tank 2, the bottom end of the output end of the liquid CO2 storage tank 1 is fixedly connected to a reaction pump 1, including the bottom end of the output end of the liquid CO2 storage tank 2 is fixedly connected to a reaction pump 2, the output end of the reaction pump 1 is fixedly connected to a reactor 1, and the output end of the reaction pump 2 is fixedly connected to a reactor 2.

[0006] The beneficial effects of the carbon dioxide gas phase recovery system of the utility model are:

[0007] Liquid CO2 is purchased from external units and enters the interior of liquid CO2 storage tank one and liquid CO2 storage tank two. As the CO2 in the tanks continues to evaporate, the pressure of the tanks continues to increase, and the evaporated gaseous carbon dioxide enters the interior of the compressor. The compressed liquid carbon dioxide is cooled by the refrigerator and returned to the interior of liquid CO2 storage tank one and liquid CO2 storage tank two, thereby achieving partial economic benefits, reducing carbon dioxide loss, and saving energy and reducing emissions. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0012] According to one aspect of the present invention, Figure 1 As shown, a carbon dioxide gas phase recovery system is provided, including a liquid CO2 storage tank 1, the liquid CO2 storage tank 1 is fixedly connected to a liquid CO2 storage tank 2, the top ends of the output ends of the liquid CO2 storage tank 1 and the liquid CO2 storage tank 2 are fixedly connected to a compressor 3, the output end of the compressor 3 is fixedly connected to a refrigerator 4, the output end of the refrigerator 4 is fixedly connected to the liquid CO2 storage tank 2, the bottom end of the output end of the liquid CO2 storage tank 1 is fixedly connected to a reaction pump 5, including the bottom end of the output end of the liquid CO2 storage tank 2 is fixedly connected to a reaction pump 6, the output end of the reaction pump 5 is fixedly connected to a reactor 7, and the output end of the reaction pump 6 is fixedly connected to a reactor 8;

[0013] Liquid CO2 is purchased from an external unit and enters the interior of liquid CO2 storage tank 1 and liquid CO2 storage tank 2. As the CO2 in the tanks continues to evaporate, the pressure of the tanks continues to increase, and the evaporated gaseous carbon dioxide enters the interior of compressor 3. The compressed liquid carbon dioxide is cooled by refrigerator 4 and then returns to the interior of liquid CO2 storage tank 1 and liquid CO2 storage tank 2, thereby achieving partial economic benefits.

[0014] The working principle of this device is: liquid CO2 is purchased from an external unit and enters the interior of liquid CO2 storage tank 1 and liquid CO2 storage tank 2. Since the CO2 in the tank will continue to evaporate, the pressure of the tank will continue to increase, and the evaporated gaseous carbon dioxide enters the interior of the compressor 3. The compressed liquid carbon dioxide is cooled by the refrigerator 4 and then returned to the interior of the liquid CO2 storage tank 1 and liquid CO2 storage tank 2, thereby achieving partial economic benefits.
