Description

Technical Field

[0001] The utility model relates to the technical field of gas purification, in particular to a gas purification vertical tank. Background Art

[0002] Most gas purification technologies use adsorbents and catalysts to remove trace impurities such as nitrogen, oxygen and water from high-purity gases by adsorption and catalysis at room temperature or variable temperature. When the adsorbent in the purifier is saturated with a certain impurity component, the adsorbent must be replaced or regenerated in order to meet the purification index. Usually, due to the large number of impurities in the gas, in order to remove all impurities at one time, one solution is to connect multiple purifiers or tanks in series, each purifier or tank is equipped with a different getter. This solution requires the configuration of multiple purifiers or tanks to ensure the airtightness of multiple gas paths. Since there are usually physical or chemical reactions in the gas purification process, the welded purification tank is prone to pressure at the weld to produce gas leakage, and there is no time for personnel to stop the buffer; at the same time, the purification efficiency of the existing purification tank needs to be improved.
