Technical Field

[0001] The utility model relates to the field of carbon dioxide production, in particular to a liquefaction device for carbon dioxide production. Background Art

[0002] Large-scale emissions of greenhouse gases will lead to global warming, and carbon dioxide is the greenhouse gas with the largest emission. At the same time, carbon dioxide is an important resource. It is not only widely used but also in increasing demand, such as refrigerants, food additives, fire extinguishing agents, chemical raw materials, oil and gas extraction, agricultural production, etc. If the raw gas containing carbon dioxide is simply discharged into the atmosphere, it will not only cause a waste of carbon resources, but also cause pollution to the atmospheric environment.

[0003] A Chinese patent discloses a liquefaction device for high-purity carbon dioxide production (authorization announcement number CN 212778202U). This patented technology can solve the problem that the existing liquefaction efficiency of high-purity carbon dioxide production liquefaction devices is relatively low, thereby increasing the cost of liquefaction.

[0004] However, the existing liquefied carbon dioxide is transported through a single pipeline, which results in a fast flow rate, makes the pipeline joints prone to vibration, and makes the pipeline prone to rupture, requiring frequent replacement. Summary of the invention

[0006] Preferably: the left and right side walls in the bottom cavity are symmetrically installed with electric sliders, the inner end of the electric slider is installed with a bottom plate through a connecting frame, and the upper surface of the bottom plate is installed with a round table.

[0007] Preferably: a plug post is installed on the upper surface of the bottom plate, and a slot matching the plug post is provided at the bottom of the truncated cone.

[0008] Preferably: a plurality of annular sleeves are installed on the upper end surface of the circular table along its circumferential direction, and a liquefaction chamber is installed on the inner end of the annular sleeve.

[0010] Preferably: a sponge pad is installed at the bottom of the bottom cavity, and the spring rod passes through the sponge pad.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model adopts a main pipe and branch pipe structure, so that the liquefied carbon dioxide can be diverted and processed, effectively alleviating the problem that the interface is unstable due to the excessive flow rate of the liquefied carbon dioxide, and the need for frequent maintenance and replacement.

[0013] 2. The utility model adopts a liquid level sensor and a control valve structure, so there is no need to observe the internal capacity of each liquefaction chamber in real time, further liberating labor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 4In this embodiment, a liquefaction device for carbon dioxide production is provided, including a bottom chamber 1 and a liquefaction chamber 2. A truncated cone 11 is arranged in the bottom chamber 1, and a plurality of liquefaction chambers 2 are installed on the upper end surface of the truncated cone 11 along its circumferential direction. A branch pipe 12 is arranged in the liquefaction chamber 2, and a connector 13 is installed at the other end of the branch pipe 12. A main pipe 14 is installed on the upper end surface of the connector 13. A control valve 15 is installed on the outer side wall of the branch pipe 12, and a liquid level sensor 16 is arranged below the control valve 15. A control panel 17 is installed on the left end surface of the bottom chamber 1, and the control panel 17 is electrically connected to the liquid level sensor 16. The control panel 1 A PLC program is written in 7 to control the operation of each device. When working, the liquefied carbon dioxide enters the main pipe 14, and is diverted into the branch pipe 12 through the connector 13, thereby effectively alleviating the problem that the interface is unstable due to the excessive flow rate of the liquefied carbon dioxide, and frequent maintenance and replacement are required. The carbon dioxide is stored in the liquefaction chamber 2 through the branch pipe 12. The liquid level sensor 16 can sense the liquid level height of the corresponding liquefaction chamber 2. When it is full, the corresponding control valve 15 is controlled to close, so there is no need to observe the internal capacity of each liquefaction chamber 2 in real time, which further liberates labor.

[0021] The left and right side walls of the bottom chamber 1 are symmetrically installed with electric sliders 18, the inner end of the electric slider 18 is installed with a bottom plate 19 through a connecting frame, and the upper end surface of the bottom plate 19 is installed with a round table 11. When working, the electric slider 18 is a linear guide slider structure, and the motor drives the lead screw to rotate to control the linear movement of the device. When the liquefaction chamber 2 is full, the electric slider 18 is started to control the round table 11 to move downward, so that the liquefaction chamber 2 is separated from the branch pipe 12, thereby facilitating the replacement and transportation of the liquefaction chamber 2, and the operation is convenient.

[0022] The upper end surface of the bottom plate 19 is provided with a plug post 21 , and the bottom of the truncated table 11 is provided with a slot for matching with the plug post 21 . When working, the plug post 21 limits the truncated table 11 to avoid sliding friction between the bottom plate 19 and the truncated table 11 .

[0023] A plurality of annular sleeves 22 are installed along the circumferential direction of the upper end surface of the truncated cone 11 , and a liquefaction chamber 2 is installed at the inner end of the annular sleeve 22 . When working, the annular sleeve 22 limits and fixes the liquefaction chamber 2 to prevent the liquefaction chamber 2 from deviating and causing collision damage to the branch pipe 12 .

[0024] A base 23 is installed at the bottom of the bottom cavity 1, a bottom groove is installed on the upper end surface of the base 23, and a spring rod 24 is installed at the bottom of the bottom groove. When working, the spring rod 24 plays a certain supporting role on the base 23 to ensure that the base 23 moves down slowly.

[0025] A sponge pad 25 is installed at the bottom of the bottom chamber 1, and the spring rod 24 passes through the sponge pad 25. When working, the sponge pad 25 provides shock absorption protection for the base 23, thereby preventing the liquefied chamber 2 from shaking and causing leakage of liquefied carbon dioxide.

[0026] During specific operation, the liquefied carbon dioxide enters the main pipe 14, and is diverted into the branch pipe 12 through the connector 13, thereby effectively alleviating the problem of instability at the interface caused by the excessive flow rate of liquefied carbon dioxide, which requires frequent maintenance and replacement. The carbon dioxide is stored in the liquefaction chamber 2 through the branch pipe 12, and the liquid level sensor 16 can sense the liquid level height of the corresponding liquefaction chamber 2. When it is full, the corresponding control valve 15 is controlled to close, thereby eliminating the need to observe the internal capacity of each liquefaction chamber 2 in real time, further freeing up labor.

[0027] Obviously, the invention described is only a part of the invention of the utility model, not the whole invention. Based on the invention in the utility model, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. The structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to the conventional means in the field unless otherwise specified and limited.
