Pressure swing adsorption nitrogen machine (PSA nitrogen machine) is an automatic equipment that uses carbon molecular sieve as the adsorbent, uses the principle of pressure adsorption and pressure drop desorption to absorb and release oxygen from the air, and then separate nitrogen. Carbon molecular sieve is a kind of coal as the main raw material, through grinding, oxidation, molding, carbonization and through a special pass processing technology processing, the appearance and the interior is covered with micropores columnar granular adsorbent, black.
The pore size dispersion of carbon molecular sieves enables the kinetic separation of O2 and N2. Such pore dispersion allows different gases to disperse at different rates into the micropores of the molecular sieve without crowding out any of the gases in the mixture (air). The separation effect of carbon molecular sieve on O2 and N2 is based on the small difference in the kinetic diameter of the two gases. The kinetic diameter of O2 molecule is small, so it has a faster dispersion rate in the micropores of carbon molecular sieve, while the kinetic diameter of N2 molecule is large, so the dispersion rate is slow. The dispersion of water and CO2 in compressed air is not much different from that of oxygen, while argon disperses more slowly. Finally, the mixture of N2 and Ar is enriched from the adsorption tower.
The addition of adsorption pressure can increase the adsorption capacity of O2 and N2 together, and the increase fluctuation of O2 adsorption capacity is larger. The pressure swing adsorption period is short, and the adsorption amount of O2 and N2 is far from reaching the equilibrium (maximum value), so the difference in the dispersion rate of O2 and N2 makes the adsorption amount of O2 greatly exceed the adsorption amount of N2 in a short time.
PSA nitrogen making machine (PSA nitrogen making machine) is the use of carbon molecular sieve selection adsorption characteristics, the selection of pressure adsorption, decompression desorption cycle, so that compressed air replacement into the adsorption tower (can also be completed in a single tower) to complete the air separation, and then successive production of high purity commercial nitrogen.
