Adjustable Oxygen Capacity And Purity Of PSA Oxygen Making Machine In Appropriate Range

Working Principle Description:

After compressed by the air compressor, the raw air enters the air storage tank after dust removal, oil removal and drying, and then enters the left adsorption tower through the left air inlet valve. At this time, the tower pressure increases, the nitrogen molecules in the compressed air are adsorbed by the zeolite molecular sieve, and the non adsorbed oxygen passes through the adsorption bed and enters the oxygen buffer tank through the outlet valve. This process is called adsorption. After the adsorption process, the left adsorption tower and the right adsorption tower are connected through the pressure equalizing valve to equalize the pressure of the two towers.

This process is called pressure equalizing. After pressure equalization, the compressed air passes through the right air inlet valve and enters the right adsorption tower to repeat the above adsorption process. At the same time, the oxygen adsorbed by the molecular sieve in the left adsorption tower is decompressed and released to the atmosphere through the left vent valve. This process is called desorption, adsorbing the saturated molecular sieve to obtain regeneration. Similarly, when the left tower adsorbs, the right tower also desorbs. After the adsorption of the right tower, it also enters the pressure equalization process, and then switches to the adsorption of the left tower. In this way, the cycle is alternating to continuously produce oxygen.
