Energy-saving skid-mounted integrated small oxygen generator

Energy-Saving Oxygen Generator utilizes high-quality zeolite molecular sieve as the adsorbent and employs the pressure swing adsorption principle to directly extract oxygen from compressed air.

Working Principle: Compressed air enters the adsorption tower filled with zeolite molecular sieve. Nitrogen, carbon dioxide, water vapor, and other components in the air are largely adsorbed by the molecular sieve, while oxygen, due to its higher diffusion rate, passes through the adsorbent and is separated. When the adsorbed impurities such as nitrogen in the adsorption tower reach a certain level, the pressure is reduced to desorb the zeolite molecular sieve, regenerating the adsorbent for repeated cyclic use.
Energy-Saving Oxygen Generator Workflow
After the air is compressed by the air compressor, the cubic oxygen generator undergoes dust removal, oil removal, and drying before entering the air storage tank. It then passes through the air intake valve and left intake valve into the left adsorption tower. The pressure in the cubic oxygen generator tower increases, and the nitrogen molecules in the compressed air are adsorbed by the zeolite molecular sieve. The unadsorbed oxygen passes through the adsorption bed, enters the oxygen storage tank via the left gas production valve and oxygen production valve. This process is called left adsorption and lasts for several tens of seconds. After the left adsorption process ends, the left and right adsorption towers are connected through the equalizing valve to balance the pressure in both towers. This process is called pressure equalization and lasts for3~5 seconds. After pressure equalization, compressed air enters the right adsorption tower via the air intake valve and right intake valve. The nitrogen molecules in the compressed air of the cubic oxygen generator are adsorbed by the zeolite molecular sieve, and the enriched oxygen enters the oxygen storage tank through the right gas production valve and oxygen production valve. This process is called right adsorption and lasts for several tens of seconds. Simultaneously, the oxygen adsorbed by the zeolite molecular sieve in the left adsorption tower is released back into the atmosphere by depressurization through the left exhaust valve. This process is called desorption. Conversely, when the left tower is adsorbing, the right tower is simultaneously desorbing. To ensure that the nitrogen released during depressurization in the molecular sieve is completely discharged into the atmosphere, oxygen is blown through a normally open backflush valve to purge the desorbing adsorption tower, expelling the nitrogen from the tower. This process is called backflushing and occurs simultaneously with desorption. After right adsorption ends, the process enters pressure equalization, then switches to left adsorption, continuing in a cyclic manner.
