Description:

PSA principle medical usage oxygen concentrator

Air source is compressed by the air compressor, after dust removal, oil removal, and refrigerated/Adsorption drying, it passes through the diaphragm oxygen concentrator solenoid valve, the oxygen generator diaphragm normally in 4 way or 5 way (dual exhausting type),the compressed and filtrated air enters into the left adsorption Tank, the tank inside pressure increasing, and the nitrogen molecules in the compressed air due to volume size and pressurizing factors, they are adsorbed by zeolite Molecular sieve bedding at the bottom of adsorption tank , the un-adsorbed oxygen molecules passes through the adsorption molecular sieve bed, enters into oxygen storage tank. This process is called left adsorption.

After the left adsorption process is over, the left and right adsorption tanks connected by a valve to balance the two tank inner pressure, actually the left tank high pressure drop equal to the right tank inner pressure. This process is called pressure equalization, and the duration is about 3-5 seconds. After the pressure equalization process is over, the compressed clean air passes through the diaphragm oxygen generator solenoid valve, and enters into the right adsorption column and inside the adsorption column pressure increasing. The nitrogen molecules of the air are adsorbed by zeolite Molecular sieve bedding at the bottom of right adsorption column, oxygen molecules due to size of volume could not be adsorbed, it will pass through the molecular sieve bed and enters into the oxygen reservoir tank. This process is called right adsorption ,it lasts for tens of seconds. At the mean time, the nitrogen molecules which adsorbed in the zeolite molecules of the left adsorption tower is released because of depressurizing state in the tower, pumps out and exhausting to atmosphere, This process is called desorption, desorption process result in the starting over and renew capacity of zeolite molecular sieve in the tower, VICE VERSA, When the left adsorption tower is adsorbed, the right adsorption tower is desorbed. In order to completely exhausting the nitrogen released from the molecular sieve to the atmosphere, the oxygen The desorption tower is blowed through a normally open back-flush valve. This process is called backflushing. It carries out at the same time with desorption. After the right adsorption is completed, it runs the process of pressure equalization, and after that comes the process of switching to the left adsorption, so on the system continues to circulate, which enable high-purity and big flow oxygen to be produced continuously.
