Working principle
According to the principle of PSA, high quality carbon molecular sieve was used as adsorbent. At a certain pressure, due to the kinetic effect, the diffusion rate of oxygen in the micropores of carbon molecular sieve is much faster than that of nitrogen. When the adsorption does not reach equilibrium, oxygen is adsorbed by carbon molecular sieve in a large amount, and nitrogen molecules are enriched in the gas phase to achieve oxygen nitrogen separation. As the adsorption capacity of carbon molecular sieve for oxygen is significantly different with the pressure, reducing the pressure can desorb the oxygen molecules adsorbed by carbon molecular sieve, regenerate the carbon molecular sieve, and reuse it. Two adsorption tower processes are adopted, one is adsorption to produce nitrogen, the other is desorption to regenerate. PLC intelligent program controller is used to control the opening and closing of pneumatic angle valve to make the two towers cycle alternately and continuously produce high-quality nitrogen.
Technical characteristics
The imported pneumatic angle seat valve has a service life of more than 1 million times. Imported PLC intelligent program controller, easy to operate, stable operation. Reasonable internal components, uniform air distribution, reduce high-speed impact of air flow. Special molecular sieve protection measures can prolong the service life of carbon molecular sieve. Automatic linkage nitrogen emptying device to ensure the quality of product nitrogen.
