operational principle

Carbon molecular sieve is a type of carbon adsorbent, consisting of a porous material composed of carbon, with a pore structure model of disorderly stacked carbon structure. Carbon molecular sieves are non stoichiometric compounds, and their important properties are based on their microporous structure. Its ability to separate air depends on the different diffusion rates, adsorption forces, or both effects of various gases in the air in the micropores of carbon molecular sieves.

Under a certain pressure, utilizing the difference in the adsorption amount of oxygen and nitrogen on the surface of carbon molecular sieves in the air, that is, the diffusion adsorption of oxygen by carbon molecular sieves is much greater than that of nitrogen. By controlling the opening and closing of the pneumatic valve group through programmable control, the cycle process of alternating pressure adsorption and pressure reduction desorption between the two towers is achieved, completing nitrogen oxygen separation and obtaining the required purity of nitrogen.
