PURPOSE: A nitrogen adsorption apparatus of oxygen generator is provided to improve performance of zeolite by reducing moisture influence exerted on nitrogen adsorbents inside beds and easily discharges nitrogen and water by improving arrangement structure of the beds. CONSTITUTION: In a nitrogen adsorption apparatus of oxygen generator comprising cylindrical beds(41L,41R) to one side of which inlet pipe(31) is connected so that air is introduced through the inlet pipe, and to the other side of which outlet pipe is connected so that oxygen is discharged from the outlet pipe; nitrogen adsorbents arranged inside the beds to adsorb nitrogen from atmospheric air after introduction into the cylindrical beds; moisture adsorbents(43L,43R) arranged in the lower part of the nitrogen adsorbents to adsorb moisture from atmospheric air, the nitrogen adsorption apparatus of oxygen generator is characterized in that resistors(44L,44R) are positioned in the lower part of the moisture adsorbents inside the beds to condensate moisture from air by guiding pressure drop of the air, wherein the resistors are formed of alumina particles for disturbing flow of air as they are not saturated with moisture, wherein the resistors and moisture adsorbents are arranged in such a way that they are divided by meshes(45L,45R) having a certain thickness, and wherein the beds are erected in such a way that one side to which the inlet pipe is connected is positioned at the lower part of the beds while the other side to which the outlet pipe is connected is positioned at the upper part of the beds, and purge pipe(70) is connected to one side of the beds so that nitrogen adsorbed on the nitrogen adsorbents is discharged through the purge pipe along with water during the regeneration process.
