VPSA oxygen generator for medical use  

Process Description  VPSA Oxygen generator, which is under the condition of atmospheric pressure, using special adsorbent ( macular sieve, and activated alumina) selective adsorption characteristics, preferential adsorption impurities such as nitrogen, carbon dioxide and water in the air, then obtain high purity oxygen under the condition of pressure. Under the condition of reduced pressure, stripping adsorbent nitrogen and other impurities, the regeneration of adsorbent. Two towers (or more) cycle work, adsorption - stripping cycle operation, so as to realize continuous production purity 90-95% oxygen. Vacuum pressurized adsorption desorption (VPSA) oxygen producing equipment, which means through atmospheric pressure conditions, the use of special molecular sieve adsorption selectivity VPSA impurities such as nitrogen, carbon dioxide and water in the air, under the condition of vacuum desorption of molecular sieve to circulately obtain high purity of oxyge…
