Description

Technical Field

[0001] This utility model relates to the field of gas processing equipment technology, and in particular to a carbon dioxide gas pressurization and precise pressure regulation device. Background Technology

[0002] Carbon dioxide, as an important industrial gas, has wide applications in many fields such as chemical engineering, food processing, and welding. In many applications, it is necessary to pressurize carbon dioxide gas from cylinders or storage tanks to meet specific process pressure requirements. Therefore, carbon dioxide gas pressurization equipment has emerged.

[0003] However, in existing technologies, carbon dioxide gas booster equipment faces a significant technical challenge in practical use. After being compressed by the booster pump, the pressure of carbon dioxide gas increases significantly. When this high-pressure gas flows through subsequent pipelines, valves, and other throttling elements, it undergoes violent throttling expansion. According to the Joule-Thomson effect, the gas temperature drops sharply, even below its triple point temperature, causing it to rapidly condense into solid carbon dioxide, i.e., dry ice, at the pipeline outlet or valve port. This dry ice accumulates rapidly, eventually clogging the entire pipeline, preventing normal gas output. This not only interrupts the production process but can also lead to safety accidents due to abnormal pressure.

[0004] Therefore, this utility model proposes a carbon dioxide gas pressurization and precise pressure regulation device to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a carbon dioxide gas pressurization and precise pressure regulation device, which aims to improve the problems in the existing technology, such as the easy formation of dry ice in the outlet pipeline due to gas throttling and cooling, leading to blockage, and the risk of gas leakage due to poor sealing at the inlet connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a carbon dioxide gas pressurization and precision pressure regulation device, including a housing, a booster pump installed inside the housing, and an inlet pipe, an outlet pipe, and an outer pipe respectively connected to the booster pump; it also includes a sealing component and a heat conduction component;

[0007] The sealing assembly is located on one side of the air intake pipe and includes a connector, a threaded joint, and a sealing ring. The threaded joint is detachably threaded to the inner wall of the connector, and the sealing ring is fitted on the outer side of the threaded joint. The sealing assembly also includes a connecting pipe that connects the connector and the air intake pipe, and the connecting pipe has a spiral channel inside.

[0008] Furthermore, the heat-conducting component is located between the air outlet pipe and the outer pipe, including a transfer box, a heat-conducting plate, a spiral ring, and a connecting rod. The heat-conducting plate is fixedly connected to the outer wall of the transfer box, the spiral ring is fixedly located inside the transfer box, one end of the connecting rod passes through the wall of the transfer box and is fixedly connected to the spiral ring, and the other end is fixedly connected to the heat-conducting plate.

[0009] Preferably, the interior of the connecting pipe is further provided with a straight channel extending along its axial direction. This straight channel is arranged in parallel with the spiral pipe. This structure allows the incoming gas to be effectively diverted, with one part passing through quickly and the other part being buffered through the spiral path, thereby improving the stability of the airflow.

[0010] Preferably, the spiral ring is a hollow pipe structure, which is used to limit the spiral flow path of the gas inside the transfer box. By extending the gas's travel distance inside the transfer box, the heat exchange time and heat exchange area are increased, thereby improving the heating effect.

[0011] Preferably, the transfer box is connected in series between the outlet of the gas outlet pipe and the inlet of the external pipe, ensuring that all high-pressure gas output from the booster pump must be processed by the heat-conducting components, thus ensuring full coverage of the anti-freezing and anti-blocking function.

[0012] Preferably, it also includes an operating console, which is fixedly installed on the top of the enclosure to provide users with a centralized operation and monitoring interface, facilitating the control of the entire device;

[0013] Preferably, it also includes an openable blade, which is installed on the housing. When it is necessary to inspect or maintain the internal components, the blade can be opened conveniently, which improves the maintainability of the equipment.

[0014] Preferably, the booster pump is also provided with a medium pipe, which provides an additional interface for the equipment, and can be used to introduce coolant, lubricant or exchange other process media, thereby enhancing the applicability and versatility of the equipment;

[0015] Preferably, the connection point between the heat-conducting plate and the connecting rod is located on the inner side of the heat-conducting plate. This arrangement shortens the physical path of heat conduction from the outside to the internal core components, which is conducive to faster and more direct heat transfer and improves the overall heat conduction efficiency.

[0027] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a carbon dioxide gas pressurization and precision pressure regulation device, including a housing 1. The housing 1 is used to carry the internal components of the device and facilitates overall movement. The housing 1 is provided with an openable and closable blade. An operating table 2 is fixedly installed on the top of the housing 1. The operating table 2 is used to operate and adjust the device. A booster pump 3 is installed inside the housing 1. The booster pump 3 is used to pressurize the carbon dioxide gas. The booster pump 3 is respectively connected to an inlet pipe 9 for inputting gas, an outlet pipe 6 for outputting high-pressure gas, and a medium pipe 5.

[0028] To solve the sealing problem at the air inlet, the device includes a sealing assembly 4, which is located on one side of the air inlet pipe 9. The sealing assembly 4 includes a connector 405, a threaded joint 403, and a sealing ring 401. The threaded joint 403 is detachably threaded to the inner wall of the connector 405 for quick connection and fixation of the pipeline. The sealing ring 401 is sleeved on the outside of the threaded joint 403. When the threaded joint 403 is screwed into the connector 405, the sealing ring 401 slides and fits against the outside of the connector 405 during the screwing process, thereby forming an effective airtight structure to prevent gas leakage.

[0029] The sealing assembly 4 also includes a connecting pipe 402, which connects the connector 405 and the air inlet pipe 9, serving as a channel for gas to flow from the connector 405 to the air inlet pipe 9; a spiral pipe 404 is provided inside the connecting pipe 402, and part of the gas entering the connecting pipe 402 flows spirally through the spiral pipe 404.

[0030] To address the condensation and blockage issue at the gas outlet, the equipment also includes a heat-conducting component 7. This component is positioned between the gas outlet pipe 6 and the external pipe 8, through which the gas ultimately exits the equipment. The heat-conducting component 7 comprises a transfer box 702, heat-conducting plates 701, and a spiral coil 704. The main body of the transfer box 702 is used to contain the flowing gas. The heat-conducting plates 701 are fixedly connected to the outer wall of the transfer box 702 to absorb heat from the external environment. The spiral coil 704 is fixedly positioned inside the transfer box 702 to extend the gas flow path within the transfer box 702 and increase the heat exchange contact area.

[0031] The structure of the heat-conducting component 7 further includes a connecting rod 703. One end of the connecting rod 703 passes through the wall of the transfer box 702 and is fixedly connected to the spiral ring 704. The other end of the connecting rod 703 is fixedly connected to the heat-conducting plate 701. With this structure, the external heat absorbed by the heat-conducting plate 701 can be efficiently conducted to the internal spiral ring 704 through the connecting rod 703, thereby heating the low-temperature and high-pressure carbon dioxide gas flowing through the spiral ring 704 and effectively preventing the gas from condensing.

[0032] The connecting pipe 402 serves as an airflow channel. In addition to the spiral pipe 404 inside, in a preferred embodiment, the connecting pipe 402 also has a straight channel extending along its axial direction inside. The straight channel is arranged in parallel with the spiral pipe 404. Part of the incoming gas flows quickly to the intake pipe 9 through the straight channel, while the other part forms turbulence through the spiral pipe 404. This diversion structure aims to disperse the airflow and reduce the direct impact on subsequent pipelines.

[0033] The transfer box 702, as the core heat exchange chamber, is connected in series between the outlet of the gas outlet pipe 6 and the inlet of the outer pipe 8, ensuring that all high-pressure gas must flow through it. The internal spiral ring 704 is preferably a hollow pipe structure and is used to limit the spiral flow path of the gas inside the transfer box 702. This design significantly prolongs the residence time of the gas in the transfer box 702 and increases the contact area between the gas and the pipe wall, thereby maximizing the heat exchange efficiency. The connecting rod 703, as a key heat-conducting bridge, is structured across the wall of the transfer box 702, firmly connecting the heat-conducting plate 701 on the outer wall and the internal spiral ring 704 into a highly efficient heat-conducting whole, ensuring that heat can be quickly transferred from the outside to the core area through which the gas flows.

[0034] As a preferred embodiment, in order to further improve the heat conduction efficiency, the inner side of the heat conduction plate 701 is fixedly connected to the connecting rod 703 to ensure that the heat is transferred from the position of the heat conduction plate 701 closest to the heat source demand side of the transfer box 702, thus shortening the heat conduction path.

[0035] As another preferred embodiment, for ease of operation and maintenance, an operating console 2 is fixedly installed on the top of the housing 1, and all adjustments to the operating parameters of the equipment are made through the operating console 2.

[0036] As another preferred embodiment, in order to facilitate the maintenance of the booster pump 3 and other components inside the housing 1, the housing 1 is provided with an openable blade, which allows access to the internal structure by opening the blade.

[0037] As a supplementary explanation, the booster pump 3 is also provided with a medium pipe 5, which can be used to introduce or discharge other auxiliary media to meet different process requirements.

[0038] Working principle: During gas pressurization, the external carbon dioxide gas source is first connected to the sealing component 4; the gas enters the connecting pipe 402 through the connector 405. Inside the connecting pipe 402, part of the gas flows directly to the intake pipe 9 through the straight channel, while the other part flows spirally through the spiral pipe 404 and then merges into the intake pipe 9; when the threaded joint 403 is tightened with the connector 405, the sealing ring 401 on its outer side will slide and fit tightly against the outer side of the connector 405 to form a reliable seal and prevent gas leakage at the intake end under high pressure.

[0039] After the gas enters the booster pump 3, it is compressed and pressurized. Then, the high-pressure, low-temperature carbon dioxide gas flows out from the outlet pipe 6 and enters the transfer box 702 of the heat-conducting component 7. In the transfer box 702, the gas flows spirally along the path of the hollow spiral ring 704. At the same time, the heat-conducting plate 701 fixed to the outer wall of the transfer box 702 absorbs the heat from the external environment. This heat is quickly conducted to the internal spiral ring 704 through the connecting rod 703, which acts as a heat-conducting bridge. The gas flowing through the spiral ring 704 exchanges heat fully with the heated pipe wall, raising its temperature. This effectively avoids the phenomenon of dry ice blockage of the pipe caused by a sudden drop in temperature due to the throttling effect.

[0040] After being heated and stabilized, the high-pressure gas finally flows out from the external pipe 8, completing the entire pressurization and anti-freezing process. Throughout the process, the operation of the booster pump 3 can be controlled and adjusted through the control panel 2 on the top of the housing 1.

[0041] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
