Problems solved by technology

The adsorption of molecular sieves to substances comes from physical adsorption (van der Waals force). There are strong polarity and Coulomb fields inside the crystal pores, which show strong adsorption capacity for polar molecules (such as water) and unsaturated molecules. It can be used for oxygen enrichment due to its different adsorption properties with oxygen, but it is difficult for existing molecular sieves to have both high adsorption capacity and nitrogen-oxygen separation coefficient

Description

Technical field [0001] The present invention relates to the field of medical devices, specifically to a medical molecular sieve oxygen system. Background [0002] With the increasing prevalence of oxygen therapy, the increase in oxygen consumption in large hospitals and the inconvenience of oxygen use in plateau areas, the solution to these problems is a large molecular sieve oxygen machine, which is the only mature oxygen concentrator with international standards and national standards. Medical molecular sieve oxygen machine has no special requirements for safety, can extract high concentration of oxygen from the air, reduce the use of liquid oxygen in hospitals, reduce the cost of oxygen, oxygen is ready to use, 24 hours continuous operation. [0003] However, because of the special characteristics of zeolite molecular sieves, the adsorption tower will reduce the adsorption efficiency due to changes in ambient temperature (usually below 5 ° C and above 25 ° C), which in turn le...
