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, the diffusion rate of oxygen in the pores of the carbon molecular sieve is much greater than that of nitrogen. When the adsorption does not reach equilibrium, the nitrogen is enriched in the gas phase to form the finished nitrogen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities to realize Reģenerācija . Parasti sistēmā ir uzstādīti divi adsorbcijas torņi, viens tornis absorbē slāpekli, bet otrs torņa desorbcija un reģenerācija .} Divi torņi tiek automātiski kontrolēti ar PLC programmu, lai diviem torņiem darbotos alternatīvi. slāpeklis .
