Metal Cutting Oxygen Generator

Features of LCO Metal Cutting Dedicated Oxygen Generator:

Utilizes imported zeolite molecular sieve adsorbent with advanced performance, low consumption, and long service life. Employs advanced and reliable oxygen generation adsorption tower technology, offering high oxygen yield and low energy consumption. High purity, reaching 90~95%, with low production costs. Stable operation, high reliability, high automation level, and excellent safety performance. Process of LCO Metal Cutting Dedicated Oxygen Generator: After 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. As the pressure in the cubic oxygen generator tower rises, nitrogen molecules in the compressed air are adsorbed by the zeolite molecular sieve, while 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, lasting several tens of seconds. After left adsorption ends, the left and right adsorption towers are connected via the equalizing valve to balance the pressure between the two towers. This process is called pressure equalization, lasting 3~5 seconds. After pressure equalization, compressed air enters the right adsorption tower through the air intake valve and right intake valve. 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 via the right gas production valve and oxygen discharge valve. This process is called right adsorption, lasting several tens of seconds. Simultaneously, the oxygen adsorbed by the zeolite molecular sieve in the left adsorption tower is released back into the atmosphere through the left exhaust valve by depressurization. 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 from 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, which occurs simultaneously with desorption. After right adsorption ends, the process enters pressure equalization again, then switches to left adsorption, continuing in a cyclic manner.

The LCO Metal Cutting Dedicated Oxygen Generator leverages the property that nitrogen molecules are larger than oxygen molecules, using a specially designed molecular sieve to separate oxygen from the air. First, a compressor forces dry air through the molecular sieve into a vacuumed adsorber. Nitrogen molecules in the air are adsorbed by the molecular sieve, while oxygen enters the adsorber. When the oxygen in the adsorber reaches a certain amount (pressure reaches a certain level), the oxygen outlet valve can be opened to release oxygen. After a period, as the molecular sieve adsorbs more nitrogen, its adsorption capacity weakens, and the purity of the produced oxygen decreases. A vacuum pump is then used to extract the nitrogen adsorbed on the molecular sieve, and the process is repeated. This method of oxygen production is also known as the adsorption method.
