Working principle

Nitrogen making machine under a certain pressure after purification of dry compressed air, under the action of pressure swing adsorption, due to the dynamic effect, oxygen and nitrogen on the surface of carbon molecular sieve diffusion rate is different, oxygen on the surface of carbon molecular sieve diffusion rate is much higher than nitrogen, in the adsorption does not reach equilibrium, oxygen is absorbed by carbon molecular sieve, nitrogen is concentrated in the gas phase. In order to achieve the separation of oxygen and nitrogen, because the adsorption capacity of carbon molecular sieve for oxygen varies significantly with the pressure, reducing the pressure can desorption the oxygen molecules adsorbed by carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused. The system sets up two adsorption towers, one tower desorption regeneration, using imported PLC control cycle alternating two towers to achieve continuous production of high-quality nitrogen.
