The industrial 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 oxygen from the air, thereby separating oxygen. Zeolite molecular sieve is a kind of spherical granular adsorbent with micropores on the surface and inside, which is processed by a special pore type treatment process, and it is white. Its pore type characteristics enable it to realize the kinetic separation of O2 and N2. Pressure swing adsorption oxygen production is based on the selective adsorption characteristics of zeolite molecular sieve. It adopts a cycle of pressure adsorption and decompression desorption to make compressed air alternately enter the adsorption tower to achieve air separation, thereby continuously producing high-purity product oxygen.
