A Brief Introduction To Industrial Oxygen Concentrators

The separation of air in industrial oxygen concentrators mainly consists of two adsorption towers filled with molecular sieves. Under normal temperature conditions, compressed air is filtered, dehydrated, dried, and purified before entering the adsorption tower. In the adsorption tower, nitrogen and other pollutants in the air are adsorbed by the molecular sieves, enriching oxygen in the gas phase and flowing out from the outlet to be stored in the oxygen buffer tank. In the other tower, the adsorbed molecular sieves are rapidly depressurized to analyze the adsorbed components. The two towers alternate to obtain cheap oxygen with a purity of ≥ 90%. The automatic switching of valves in the entire system is controlled by a computer.
