Description

Technical Field

[0001] The utility model relates to the technical field of high-purity gas purification, and specifically relates to a high-purity gas purification device. Background Art

[0002] Inert gases (argon and helium with a purity of more than 99.999%) are widely used in various fields, mainly in lasers, electronics industry, supercritical extraction, nuclear industry and scientific research. In recent years, as the production of electronic chips and flat-panel displays requires a large amount of electronic-grade helium and argon, the market demand has increased sharply. At present, the helium and argon with a purity of 99.999% sold by various gas companies are mainly packaged as high-purity raw gases. The main purification method is to react the raw gas with a getter to extract the pure gas.

[0003] When purifying gas, a storage tank is needed. When the gas in the existing storage tank is almost used up in winter, it is necessary to preheat the bottom of the storage tank to increase its internal pressure and discharge the remaining gas inside the storage tank. After searching, a high-purity gas purification device with patent number CN220981010U is found, in which a ring channel is provided on the top of the base, and a sliding rod is slidably inserted in the inner cavity of the ring channel. Two fixed plates are fixedly connected to the inner side of the sliding rod. A heating rod is provided between the two fixed plates. The heating rod is in contact with the circumferential surface of the storage tank. A fixing groove is provided in the inner cavity of the fixing groove. A driving mechanism is provided in the inner cavity of the fixing groove that can drive the sliding rod to slide in the inner cavity of the ring channel. The heating rod can heat the circumferential surface of the storage tank through the heating rod, thereby increasing the temperature of the gas inside the storage tank, realizing the ability to heat the bottom of the circumferential surface of the storage tank, thereby increasing the activity of the gas, and thereby increasing the pressure in the storage tank, so that the gas inside the storage tank can be discharged in time, and improving the utilization rate of the gas inside the storage tank.

[0004] However, the above technical solution cannot be adjusted according to the size of the storage tank and the distance between the heating rod and the storage tank during use. The farther the heating rod is from the storage tank, the lower the heating efficiency. In order to solve the above problems, a high-purity gas purification device is proposed. Utility Model Content
