Psa nitrogen making device is to use carbon molecular sieve as adsorbent, using the principle of pressure swing adsorption (psa) for nitrogen equipment.
Under a certain pressure, the use of nitrogen and oxygen in the air of the diffusion rate of differences in carbon molecular sieve is larger, the carbon molecular sieve adsorption speed is greater than for oxygen nitrogen, oxygen is carbon molecular sieve adsorption in great quantities, enrichment of nitrogen molecules in the gas phase, the separation of oxygen and nitrogen; At the same time as the carbon molecular sieve oxygen adsorption capacity varies with the different of pressure have significant differences, reduce stress, can desorption of carbon molecular sieve adsorption oxygen, carbon molecular sieve regeneration, to repeat to recycle.
Using two or more towers adsorption tower process, by using technology of PLC program control tower to produce nitrogen adsorption, the desorption tower regeneration, cycles, the continuous production of high quality nitrogen.
