Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production equipment, in particular to an industrial oxygen generator. Background Art

[0002] The industrial 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 sieve, and oxygen is enriched in the gas phase, flowing out from the outlet and 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%. The automatic switching of the valves of the entire system is automatically controlled by a computer. The industrial oxygen generator is favored by the majority of users because of its significant advantages. It is widely used in metallurgical combustion, chemical industry, environmental protection, building materials, light industry, medical treatment, aquaculture, biotechnology, sewage treatment and other fields.
