| 摘要 |
<p>This invention concerns the apparatus for producing oxygen, comprising a zeolite bed system connected to an external air pressurizing means and a vacuum pump to increase or decrease the internal pressure for producing oxygen; a carbon molecular sieve bed system adsorbing oxygen generated in the zeolite bed system and supplying oxygen which is not adsorbed into the zeolite bed, and then the carbon molecular sieve bed producing oxygen by decreasing the inner pressure, it further relates the method for controlling the above apparatus, comprising; the first step of increasing the internal pressure of the zeolite bed system to adsorb nitrogen and to produce oxygen; the second step of supplying oxygen produced in the zeolite bed system to the carbon molecular sieve bed system to increase the pressure in the carbon molecular sieve bed system and to adsorb oxygen; the third step of supplying oxygen which is not adsorbed in the carbon molecular sieve bed system to the zeolite bed system; and the fourth step of decreasing the internal pressure of the carbon molecular sieve bed system to discharge oxygen produced therein to an external device.</p> |
