Laser Cutting Machine N2 3LPM PSA Nitrogen Generator manufacturers take you to understand how the nitrogen generator works
Laser Cutting Machine N2 3LPM PSA Nitrogen Generator The manufacturer tells you that when the mixed gas is under the effect of the pressure difference on both sides of the membrane, the gas permeability is relatively fast, such as water, hydrogen, helium, hydrogen sulfide and carbon dioxide passing through the membrane, and the permeability of the cell membrane. The permeability and side are enriched, and the gas permeation rate is relatively slow, such as methane, carbon monoxide, nitrogen, argon and other gases are trapped on the film side and enriched, and then achieve the purpose of separation of mixed gases.
Carbon molecular sieve adsorbs oxygen and nitrogen in the air together, and its adsorption capacity also increases with the increase of pressure. The manufacturer of Laser Cutting Machine N2 3LPM PSA Nitrogen Generator tells you that under the same pressure, there is no significant difference in the equilibrium adsorption capacity of oxygen and nitrogen. Therefore, it is difficult to achieve effective oxygen and nitrogen separation only by changing the pressure.
The manufacturer of Laser Cutting Machine N2 3LPM PSA Nitrogen Generator tells you that if you further consider the adsorption rate, the adsorption functions of oxygen and nitrogen can be effectively separated. The diameter ratio of nitrogen and oxygen molecules is small, so the diffusion speed is hundreds of times faster than nitrogen, so the adsorption speed of carbon molecular sieve for oxygen adsorption is also very fast, reaching more than 90% in about 1 minute; only 5% nitrogen can adsorb, so the general The rest of the body that absorbs oxygen.
