Medical gas equipments type psa oxygen generator

Short Description:

The pressure adsorption oxygen generator is an automatic equipment that uses zeolite molecular sieve as an adsorbent to absorb and release oxygen from the air using the principle of pressurized adsorption and decompression desorption. Zeolite molecular sieve is a kind of spherical granular adsorbent with microporous surface and interior, which is white. Its pore type characteristics enable it to achieve the kinetic separation of oxygen and nitrogen. The separation of oxygen and nitrogen from zeolite molecular sieves is based on the slight difference in the kinetic diameter of these two gases. The nitrogen molecules have a faster diffusion rate in the micropores of zeolite molecular sieves and the oxygen molecular diffusion rate is slow. The diffusion of water and carbon dioxide in compressed air is not much different from nitrogen. It is the oxygen molecules that are eventually enriched from the adsorption tower. Subpressure adsorption oxygen production is the use of zeolite molecular sieve selection adsorption characteristics, pressure adsorption, decompression desorption cycle, so that the compressed air alternately into the adsorption tower to achieve air separation, thus continuously produce high-purity product oxygen.
