PSA nitrogen making machine
Principle
Compressed air that has been purified and dried under a certain pressure undergoes pressure swing adsorption. Due to dynamic effects, the diffusion rates of oxygen and nitrogen on the surface of carbon molecular sieves are different. The diffusion rate of oxygen on the surface of carbon molecular sieves is much higher than that of nitrogen. When the adsorption does not reach equilibrium, oxygen is heavily adsorbed by carbon molecular sieves, and nitrogen is concentrated and enriched in the gas phase, achieving oxygen nitrogen separation. Due to the significant difference in oxygen adsorption capacity of carbon molecular sieves with different pressures, reducing the pressure can desorb the oxygen molecules adsorbed by the carbon molecular sieves, allowing them to regenerate and be reused. The system is equipped with two adsorption towers, one for nitrogen production through adsorption and the other for desorption regeneration. The imported PLC is used to control the circulation of the two towers to achieve continuous production of high-quality nitrogen.
