NZN-LZ series liquid nitrogen equipment is based on the principle of pressure swing adsorption, using high-quality carbon molecules as adsorbents to produce nitrogen from the air under a certain pressure. The purified and dried compressed air is subjected to pressure adsorption and decompression desorption in the adsorber. Due to the kinetic effect, Diffusionshastigheden af ilt i porerne på carbonmolekyltasningen er meget større end nitrogen . Når adsorptionen ikke når ligevægt, er nitrogenet beriget i gasfasen for at danne den færdige nitrogen . Derefter reduceres trykket til normalt tryk, og adsorbenten desorbs the adsor. oxygen and other impurities to realize regeneration. Generally, two adsorption towers are set up in the system, one tower absorbs nitrogen and the other tower desorption and regeneration. The two towers are automatically controlled by the PLC program to make the two towers work alternately. The finished nitrogen gas is then passed through a Stirling køleskab til fremstilling af flydende nitrogen .
