principle
The oxygen generator device is carefully developed using the principle of PSA pressure swing adsorption, using a high-quality oxygen making molecular sieve as the adsorbent to directly separate oxygen from the air at room temperature. Compressed air subjected to dry purification treatment. Entering the adsorption tower equipped with molecular sieves, nitrogen, carbon dioxide, moisture, etc. in the air are largely adsorbed into the molecular sieve solid phase, while oxygen is enriched in the gas phase due to the small adsorption amount.

Process
Air compressor system
The oxygen concentrator air compressor system mainly includes an air compressor and an air buffer tank. The air is compressed to the set pressure value through the air compressor and the air pressure is stabilized by the buffer tank.
Compressed air purification system
The compressed air purification system compression of the oxygen concentrator includes a funny degreaser, a refrigerated dryer, an activated carbon filter, and a precision filter. The air is first removed from part of the oil, water, dust by the gas-water separator, pipe filter, then further removed by the combined dryer, the fine filter removes oil, dust, and is deeply purified by a precision filter that follows.
PSA adsorption system
It mainly consists of an oxygen filtration system, an oxygen buffer tank, a CNC system, an oxygen analyzer, and a flow meter. Oxygen taken from the PSA oxygen production mechanism will first be stored in an oxygen buffer tank. Oxygen Buffer Tank Function: Balances the pressure and oxygen content of the product gas and provides a regenerative gas source for the process tank of the oxygen-nitrogen separation device.
Oxygen buffer system
The core part of the oxygen generator is the PSA adsorption system, which consists of an air process storage tank, adsorption tower, pneumatic valve, PLC controller, and compression device. The compressed and purified gas passes through the oxygen-generating molecular sieve of the adsorption tower to separate the produced oxygen. The dual-tower structure One tower adsorption oxygen production, one tower desorption regeneration, combined with PLC controlled cycle alternating two towers, produces high quality oxygen.
