Description

TECHNICAL FIELD

[0001] The utility model relates to a container tank applied to gas purification in the technical field of gas purification. BACKGROUND

[0002] Gas purification technology has a wide range of applications in industrial production, scientific research and environmental protection, and is particularly important in the extraction and purification of rare gases (such as helium, argon, etc.). Due to its unique physical and chemical properties, rare gases are widely used in high-tech fields such as semiconductor manufacturing, medical equipment, aerospace, etc. 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 a key to technological development.

[0003] In the existing gas purification process, compression, cooling and separation steps are usually used to remove impurities (such as water vapor, oil stains, etc.) in the gas. Specifically, the gas is compressed by a compressor and then enters a cooling device to lower the temperature, causing the water vapor and oil vapor in the gas to condense into liquid, which is then separated from the pure gas by a gas-liquid separation device. The separated liquid impurities (mainly water and oil mixture) are usually collected in a blowdown tank, while the pure gas is used or stored in the next stage.

[0004] However, there is a significant problem in the existing technology: during the gas-liquid separation 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 wastes rare gas resources, but also can cause environmental pollution. For example, in the helium purification process, helium is a scarce and non-renewable resource, and its loss will directly increase production costs and have a negative impact on resource sustainability. In addition, the discharged liquid impurities may contain trace amounts of harmful gases or volatile organic compounds, further exacerbating environmental problems. SUMMARY

[0022] Referring to Figures 1-3 The utility model proposes a container tank applied to gas purification, the internal space of the container tank is divided into the buffer chamber 2 located above the partition plate 1 and the sewage storage chamber 3 located below the partition plate 1 by the partition plate 1, the gas permeation hole 1a for communicating the buffer chamber 2 and the sewage storage chamber 3 and the waterproof gas permeation membrane covering the gas permeation hole are formed on the partition plate 1.

[0023] The container tank has the gas inlet 4, the gas outlet 5, the sewage inlet 6 and the sewage outlet, and the gas inlet 4 and the gas outlet 5 of the container tank are communicated with the buffer chamber 2 of the container tank respectively, and the sewage inlet 6 and the sewage outlet of the container tank are communicated with the sewage storage chamber 3 of the container tank respectively.

[0024] When carrying out gas purification, the raw material gas to be purified enters the buffer chamber 2 from the gas inlet 4 of the container tank, is discharged from the gas outlet 5 and is compressed by the compressor and is cooled by the cooling equipment, so that the purified gas enters the next process, and the liquid impurities separated out, mainly the mixture of water and oil, enter the sewage storage chamber 3, so that the gas dissolved or entrained in the liquid impurities directly enters the buffer chamber 2 through the gas permeation hole 1a arranged on the partition plate 1, to flush and purify the raw material gas.

[0025] From the above, the utility model utilizes the partition plate 1 to divide the internal space of the container tank into the buffer chamber 2 and the sewage storage chamber 3, and makes the buffer chamber 2 be above the sewage storage chamber 3, to integrate the gas buffering and the sewage discharge in one container tank, so that the raw material gas can be buffered in the buffer chamber 2 during purification, and the liquid impurities generated during the purification process can be buffered in the sewage storage chamber 3 west of the buffer chamber 2. Meanwhile, the gas permeation hole 1a for communicating the buffer chamber and the sewage storage chamber 3 is arranged at the central part of the partition, and the waterproof gas permeation membrane is arranged at the gas permeation hole 1a, so that the gas mixed in the liquid impurities entering the sewage storage chamber 3 can enter the buffer chamber 2 through the gas permeation hole 1a, which is beneficial to the structure simplification of the gas purification equipment on the one hand, avoids the waste of gas resources on the other hand, and also solves the problem of air pollution without adding the tail gas treatment process.

[0026] Further, the inlet 6 of the container tank is arranged on the side wall of the storage chamber 3 close to the partition plate 1. This arrangement can make the gas dissolved or entrained in the liquid impurities escape from the liquid quickly and enter the buffer chamber 2 through the gas permeable hole quickly during the downward flow of the liquid impurities, thereby significantly optimizing the gas-liquid separation effect and improving the gas recovery efficiency.

[0027] With reference to Figure 4 In this embodiment, a hole plate 11 is arranged below the inlet 6, and a piercing needle with a pointed end upward is arranged on the hole plate 11. The hole plate is used to remove the gas bubbles entrained in the liquid impurities, and the piercing needle is used to pierce the gas bubbles to make the gas escape from the liquid.

[0028] Alternatively, the inlet 6 is arranged tangentially along the side wall of the storage chamber 3 to the inside of the storage chamber 3. This arrangement can make the liquid impurities spiral down along the inner wall of the storage chamber 3 after entering, so as to increase the liquid surface area and accelerate the gas release, thereby helping the gas in the liquid impurities to be discharged faster. Further, a spiral groove is arranged on the inner wall of the storage chamber 3, and the starting end of the spiral groove is connected to the inlet 6. This arrangement can guide the entering liquid impurities to spiral down through the spiral groove.

[0029] In addition, the gas inlet 4 of the container tank is arranged on the side wall of the buffer chamber 2 close to the partition plate 1. This structural design can make the raw material gas entering through the gas inlet 4 flow together with the gas entering through the gas permeable hole to the gas outlet 5 quickly, thereby reducing the turbulence phenomenon of the gas below and reducing the energy loss, and making the gas flow more stable. In this embodiment, the gas inlet 4 and the inlet 6 are arranged at intervals in the circumferential direction of the container tank, so as to reduce the interference between them. In this embodiment, the gas permeable hole is arranged at the center of the partition plate 1, so as to reduce the interference of the gas inlet, the liquid inlet, and the gas outlet.

[0030] In this embodiment, a filter 8 is arranged in the buffer chamber 2, the gas inlet end of the filter 8 is downward and communicated with the buffer chamber 2, and the gas outlet end of the filter 8 is connected to and communicated with the gas outlet 5 of the container tank. This arrangement can filter the raw material gas by using the filter 8.

[0031] Further, the container tank comprises a tank body 9 and a tank cover 10 detachably arranged on the top of the tank body 9, the gas outlet 5 is arranged on the tank cover 10, and the filter 8 is fixedly arranged on the tank cover 10. Integrating the gas outlet 5 and the filter 8 on the tank cover 10 can reduce the complexity of the external pipeline, make the equipment structure more compact, and save the installation space. In addition, the detachable design of the tank cover 10 can facilitate the inspection and cleaning of the inside of the container tank, especially when the filter 8 needs to be replaced or the inner wall of the tank body 9 needs to be cleaned, the operation is more convenient. Further, the filter 8 is fixedly arranged on the tank cover 10, so that the filter 8 can be simultaneously detached and replaced when the tank cover 10 is detached, thereby reducing the maintenance time and workload.

[0032] From above, the utility model discloses a partition board 1 with the container jar internal space is divided into buffer chamber 2 and the sewage storage chamber 3, and make buffer chamber 2 be in the upper of sewage storage chamber 3, to buffer and the pollution discharge integration in a container jar with gas, to make raw gas in the purification buffer chamber 2 buffering, and the liquid impurity produced in the purification process can enter the buffer chamber 2 west sewage storage chamber 3 caching.Simultaneously, the central part on the partition is set up the air -permeable mouth 1a of buffer chamber 2 and sewage storage chamber 3 intercommunication, and is set up waterproof air -permeable film at air -permeable mouth 1a, to make the gas mixed in the liquid impurity enter sewage storage chamber 3 can pass through air -permeable mouth 1a and enter buffer chamber 2, so on one hand have the structure simplification of gas purification equipment;On the other hand, avoid the waste of gas resources;Meanwhile, under the condition of not adding tail gas treatment procedure, the air pollution problem is solved.
