How PSA oxygen generator work?
The pressure swing adsorption oxygen generator is an automatic equipment that uses zeolite molecular sieve as the adsorbent, and uses the principle of pressure adsorption and decompression desorption to adsorb and release nitrogen from the air, thereby separating oxygen. Zeolite molecular sieve is processed by a special pore type treatment process, and the spherical particle adsorbent full of micropores on the surface and inside is white. Its pore type characteristics enable it to realize the dynamic separation of O2 and N2. The separation effect of zeolite molecular sieve on O2 and N2 is based on the slight difference in the kinetic diameters of these two gases. N2 molecules have a faster diffusion rate in the micropores of zeolite molecular sieves, while O2 molecules have a slower diffusion rate. The diffusion of water and CO2 in compressed air is not much different from that of nitrogen. The final enrichment from the adsorption tower is oxygen molecules.
The principle of pressure swing adsorption is to use the selective adsorption characteristics of zeolite molecular sieve, adopt the cycle of pressurized adsorption and sincere pressure desorption, so that compressed air alternately enters the adsorption tower to realize air separation, thereby continuously producing high-purity product oxygen.
