Technical Field

[0001] The utility model relates to the technical field of oxygen generators, in particular to a venting device for a pressure swing adsorption oxygen generator. Background Art

[0002] The oxygen generator separates air mainly by two adsorption towers filled with molecular sieves. Under normal temperature conditions, the compressed air is filtered, dehydrated, dried and purified before entering the adsorption tower. In the adsorption tower, nitrogen and other gases in the air are adsorbed by the molecular sieves, and oxygen is enriched in the gas phase. It flows out from the outlet and is stored in the oxygen buffer tank. In the other tower, the molecular sieve that has completed the adsorption is rapidly depressurized to analyze the adsorbed components. The two towers are circulated alternately to obtain cheap oxygen with a purity of ≥90%.
