2. How it works ?
The raw air will be removed its particle by inlet filter and then be pressurized to about 40Kpa.
The air temperature from the air blower is about 75C, after to be cooled by cooling water, it will flows into one of adsorption tower which filled with adsorber.When the raw air flows from the bottom tower to upper tower, the
nitrogen will be adsorbed, oxygen will be oncentrated at the top of tower and be delivered out as product gas.
When the adsorber almost reaches to saturation, in the action of controller, the valves will be switched, the rawair flows into annotheradsorption tower to adsorb. Saturated adsorption tower will be decompressurized to atmosphere pressure andthen be vacuumized to about -60Kpa,product gas will be introduced into the tower to pruge the adsorption bed, thereby,the adsorber will bedesorbed, and prepare for the next cycle.
The two adsorption towers adsorb and desorb alternately to produce oxygen gas continuously.Raw air shifting from one adsorption tower to another tower is controlled by pneumatic valves, the action process of valves is realized by PLC controller. Centralized control system enables the whole system to work automatically.
