150Nm3/Hr Molecular Sieve Oxygen Making Machine With Compact Structure

Compact Structure Of Oxygen Making Machine With High Quality Molecular Sieve Used In Industry

Working Principle Description:

After being 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 inlet valve. At this time, the tower pressure increases, the nitrogen molecules in the compressed air are adsorbed by zeolite molecular sieve, and the oxygen that is not adsorbed passes through the adsorption bed and enters the oxygen buffer tank through the outlet valve. This process is called adsorption and lasts for tens of seconds. After the adsorption process, the left adsorption tower and the right adsorption tower are connected through the pressure equalizing valve, so that the pressure of the two towers reaches equilibrium.

This process is called pressure equalizing, and the duration is about 3 ~ 5 seconds. After pressure equalization, the compressed air passes through the right inlet valve and enters the right adsorption tower to repeat the above adsorption process. At the same time, the oxygen absorbed by the molecular sieve in the left adsorption tower is decompressed and released to the atmosphere through the left exhaust valve. This process is called desorption. The saturated molecular sieve is adsorbed and regenerated. Similarly, when the left tower adsorbs, the right tower also desorbs. After the adsorption of the right tower is completed, it also enters the pressure equalizing process, and then switches to the adsorption of the left tower, so as to produce oxygen continuously.
