Molecular sieve oxygen generator is a new equipment based on PSA technology to extract oxygen from the air. It uses molecular sieve physical adsorption and desorption technology to fill molecular sieve in the oxygen generator. Nitrogen in the air can be absorbed under pressure, while the remaining unabsorbed oxygen is collected, which becomes high purity oxygen after purification.The specific working process is that after the compressed air is purified by the air purification dryer, it enters into adsorption tower through the switching valve. In the adsorption tower, nitrogen is adsorbed by molecular sieve, and oxygen is accumulated at the top of the adsorption tower and enters the oxygen storage tank. After filtered by odor removal, dust removal filter and bacteria removal filter, finally qualified medical oxygen is obtained.
Molecular sieves for home oxygen production are generally 13X (NaX) and 5A (CaA). The oxygen absorption rate of 13X was about 47% and that of 5A was about 54%. There are also higher absorbent CaX (71%) and LiX (82%) .
