The PSA pressure swing adsorption nitrogen generator consists of two pressure vessels that are alternately switched to adsorb oxygen molecules. The containers are filled with carbon molecular sieves, which are specially used to adsorb oxygen.adsorbent. The compressed air enters one of the A towers. At this time, the oxygen will be adsorbed by the carbon molecular sieve and the nitrogen will be collected through the container. When the pressure container absorbs oxygen, itAt this time, another tower B is performing regeneration and desorption, which is to discharge the oxygen molecules adsorbed on the carbon molecular sieve into the atmosphere with a small amount of nitrogen. When the adsorption tower is saturated, regenerationThe tower is also regenerated, and then switched to tower B for adsorption, and tower A is regenerated. Based on this principle, the two towers automatically switch to maintain the purity through PLC controller.
