LDH series liquid nitrogen equipment is based on the principle of variable pressure adsorption. The high quality carbon molecular sieve is used as adsorbent. Under certain pressure, nitrogen is produced from the air.
After purifying and drying the compressed air, pressure adsorption and decompression are carried out in the absorber.
Due to the kinetic effect, the diffusion rate of oxygen in the carbon molecular sieve is much higher than that of nitrogen. When the adsorption fails to reach equilibrium, nitrogen is enriched in the gas phase to form the finished nitrogen.
Then decompression to atmospheric pressure, adsorbents to remove the adsorption of oxygen and other impurities, to achieve regeneration.
In general, two adsorption towers are set up in the system, one tower is adsorbed to produce nitrogen, and the other tower is desorbed and regenerated, which is automatically controlled by the PLC program, so that the two towers rotate alternately.
The finished nitrogen is then produced by the Stirling refrigerator to produce liquid nitrogen.
