Description
TECHNICAL FIELD
[0001] The utility model relates to a gas purification technical field, specifically relates to a gas purification system. BACKGROUND
[0002] Gas purification technology has a wide range of applications in industrial production, scientific research and environmental protection, and other fields, especially in the extraction and purification process of rare gases (such as helium, argon, etc.), gas purification technology is particularly important. Rare gases are widely used in semiconductor manufacturing, medical equipment, aerospace and other high-tech fields due to their unique physical and chemical properties. However, the extraction and purification process of rare gases is complex, costly, and resource-limited, so how to efficiently recover and utilize these gases has become the key to technological development.
[0003] In the existing gas purification process, compression, cooling and other steps are usually used to remove impurities (such as water vapor, oil stains, etc.) in the gas. Specifically, after the gas is compressed by the compressor, it enters the cooling equipment for cooling, so that the water vapor and oil vapor in the gas are condensed into liquid to obtain pure gas without water vapor and oil vapor. The separated liquid impurities (mainly water and oil mixture) are usually collected into the blowdown tank, and the pure gas enters the next stage of use or storage.
[0004] However, the existing technology has a significant problem: during the liquid impurity discharge process, part of the gas (especially rare gas) will inevitably dissolve or entrain in the liquid impurities and be discharged into the external environment with the blowdown process. This discharge not only causes waste of rare gas resources, but also may cause environmental pollution. For example, in the helium purification process, helium, as a scarce and non-renewable resource, its loss will directly increase the production cost and have a negative impact on resource sustainable utilization. In addition, the discharged liquid impurities may contain trace amounts of harmful gases or volatile organic compounds, further exacerbating environmental problems. SUMMARY

[0021] Referring to Figure 1 The utility model provides a gas purification system, which comprises a gas inlet pipeline, a compressor 1, a power mechanism 2 for providing compression power for the compressor 1, a cooler 3, and a container tank 4.
[0022] Referring to Figures 2-3 The interior space of the container tank 4 is divided into a buffer chamber above the partition plate 5 and a sewage storage chamber below the partition plate 5 by the partition plate 5. The container tank 4 has a gas inlet and a gas outlet connected to the buffer chamber and a sewage inlet and a sewage outlet connected to the sewage storage chamber. The partition plate 5 has a gas permeation hole for connecting the buffer chamber and the sewage storage chamber. The gas inlet pipeline is connected to the gas inlet of the container tank 4. The gas outlet of the container tank 4 is connected to the gas inlet of the compressor 1. The gas outlet of the compressor 1 is connected to the gas inlet of the cooler 3. The sewage discharge port of the cooler 3 is connected to the sewage inlet of the container tank 4.
[0023] When the gas purification operation is performed, the raw gas enters the buffer chamber through the gas inlet of the container tank 4 and then enters the compressor 1 for compression. After being compressed by the compressor 1, the gas enters the cooler 3 for cooling, so that the water vapor and oil vapor in the gas are condensed into liquid to form liquid impurities, mainly a mixture of water and oil, which are discharged from the sewage outlet of the cooler 3 into the sewage storage chamber of the container tank 4. The purified gas obtained by filtering out the water vapor and oil vapor is discharged from the gas outlet of the cooler 3 to be used or stored in the next stage. The gas dissolved or entrained in the liquid impurities enters the buffer chamber through the gas permeation hole in the partition plate 5 to be purified again as raw gas. In order to prevent the liquid impurities from entering the buffer chamber, a waterproof gas permeation film is arranged inside the gas permeation hole in the embodiment. The gas permeation hole is arranged at the center position of the partition plate 5 to reduce the interference of gas inlet and liquid inlet on gas discharge.
[0024] As can be seen from the above, this utility model uses a partition plate 5 to divide the internal space of the container tank 4 into a buffer chamber and a sludge storage chamber, with the buffer chamber positioned above the sludge storage chamber. Simultaneously, the air inlet pipe is connected to the air inlet of the buffer chamber, while the air outlet of the buffer chamber is connected to the air inlet of the compressor 1. The air outlet of the compressor 1 is connected to the gas inlet of the cooler 3, and the waste liquid discharge outlet of the cooler 3 is connected to the sludge inlet of the sludge storage chamber. This structural design allows the raw gas to be buffered in the buffer chamber of the container tank 4 before entering the compressor 1, ensuring a stable air intake for the compressor 1. The waste liquid impurities discharged from the cooler 3 are discharged into the sludge storage chamber of the container tank 4, allowing the gas dissolved or entrained in the liquid impurities to enter the sludge storage chamber along with the liquid impurities, and then enter the buffer chamber through the vent, thus repurifying the raw gas. This avoids wasting gas resources, eliminates the need for corresponding exhaust gas treatment components, simplifies the equipment structure, and optimizes the gas purification process. Furthermore, integrating gas buffering and liquid sludge discharge into a single container tank 4 effectively reduces the equipment volume.
[0025] Furthermore, in this embodiment, the inlet of container 4 is located on the side wall of the sludge storage chamber near the partition plate 5. This allows gas dissolved or entrained in the liquid impurities to quickly escape from the liquid as the liquid impurities flow downwards and rapidly enter the buffer chamber through the vent, thereby significantly optimizing the gas-liquid separation effect and improving gas recovery efficiency.
[0026] In this embodiment, the air inlet of container tank 4 is located on the side wall of the buffer chamber near the partition plate 5, and the drain outlet of container tank 4 is located below its air inlet. This allows the raw material gas entering through the air inlet to flow rapidly towards the air outlet along with the gas entering through the vent, thereby reducing turbulence of the gas below, reducing energy loss, and making the gas flow more stable.
[0027] Furthermore, in this embodiment, the air inlet and the sewage inlet are spaced apart in the circumferential direction of the container tank 4 to reduce interference between them.
[0028] In this embodiment, the container tank 4 includes a tank body 41 and a detachable lid 42 mounted on top of the tank body 41, with an air outlet located on the lid 42. A filter 6 is installed inside the buffer chamber, fixedly mounted on the lid 42, and the air outlet of the filter 6 is connected to and communicates with the air outlet of the container tank 4. This structural design reduces the complexity of external piping, making the equipment structure more compact and saving installation space. Furthermore, the detachable design of the lid 42 makes the interior of the container tank 4 easy to inspect and clean, especially when the filter 6 needs to be replaced or the inner wall of the tank body 41 needs to be cleaned, making operation more convenient. Since the filter 6 is fixed on the lid 42, the filter 6 can be removed and replaced simultaneously when the lid 42 is removed, reducing maintenance time and workload.
[0029] In this embodiment, the power mechanism 2 is an electric motor.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
