PSA nitrogen is selected as the raw material, and the selective adsorption is carried out by carbon molecule, and the nitrogen and oxygen are separated by the method of pressure adsorption and desorption.
PSA nitrogen process: air purification, compressed (compressed air to remove the oil, water and dust etc.) into the adsorption tower filled with carbon molecular drying election, which in the short term by a large number of molecular oxygen carbon molecular sieve adsorption, and the adsorption of nitrogen molecules in the gas phase is small, so a large number of nitrogen enrichment. Through the upper part of the adsorption tower into the nitrogen buffer tank, while the oxygen molecules in the molecular sieve. The adsorption process is carried out in the pressure case, when the adsorption pressure dropped to normal pressure, oxygen molecules adsorbed on carbon molecular sieve escape into the atmosphere after the muffler through the tower bottom, and molecular sieve regeneration. Usually the PSA nitrogen making machine adopts the double adsorption tower in parallel to carry on the adsorption oxygen production, the desorption regeneration, realizes the separation of oxygen and nitrogen, the continuous gas supply. The above process is automatically controlled by computer control system.
