nitrogenmachine
At present all the medical oxygen machine adopts the world advanced PSA (PSA) air separation technology, which is based on attraction agent's difference in oxygen and nitrogen adsorption to realize the separation of oxygen and nitrogen. When the air enters the bed with adsorbent, the adsorption capacity of nitrogen is stronger, and the oxygen is not adsorbed, so that the high concentration oxygen can be obtained at the outlet of the adsorbent bed. Because the adsorbent has the characteristic that its adsorption amount changes with pressure, change its pressure, can make adsorption alternately carry on adsorption and desorption operation.
