变压吸附氧气设备，采用优质沸石分子筛为吸附剂，利用压吸附原理，直接从压缩空气中获得氮气。

KHO series pressure swing adsorptionOxygen generator uses high-qualityzeolite molecular sieve as adsorbent and pressure adsorption principle to obtaindirectly oxygen  gas from compressed air.

工作原理 Working Principle

压缩空气经空气净化系统除去油、水、固体尘埃等杂质后进入装有沸石子筛的吸附塔，空气中氮气、二氧化碳、水蒸汽等被分子筛大量吸附，而氧气因为扩散速率大而穿过吸附剂而实现分离。当吸附塔内吸附的氮等杂质达到一定程度后，降低压力使沸石分子解吸，使吸附剂再生，得以重复循环使用。

采用两个吸附塔在PLC的控制下循环工作，连续产出高品质氧气。

After the impurities such as oil, water and solid dust etc. are removed by the air purification system, the compressed air enters the adsorption tower equipped withzeolite molecular sieve . Nitrogen, carbon dioxide and water vapor etc. in the air are largely adsorbed by molecular sieve, while oxygen is separated through the adsorbent due to the high diffusion rate. When the nitrogen and other impurities adsorbed in the adsorption tower reach a certain degree, reducing the pressure makes thezeolite molecular sieve desorption, regeneration of the adsorbent, and reuse.            

Two adsorption towers are used under the control of PLC to produce high quality oxygen gas continuously.
