PRESSURE SWING ADSORPTION TYPE OXYGEN CONCENTRATOR

摘要

PROBLEM TO BE SOLVED: To provide a pressure swing adsorption type oxygen concentrator reducing concentration fluctuation and pressure fluctuation of product oxygen, improving pressure rising efficiency and improving oxygen generation efficiency by changing a product tank volume and reducing the fluctuation of the product tank pressure.;SOLUTION: This pressure swing adsorption type oxygen concentrator to generate oxygen concentrated gas, is provided with one or more adsorption bed storing adsorbent for at least adsorbing nitrogen more than oxygen, a raw air supply means for supplying the adsorption bed with raw air, and a channel changeover means for controlling the incoming and outgoing of gas relative to the adsorption bed, and a product tank for enabling to stably supply concentrated oxygen gas. This pressure swing adsorption type oxygen concentrator can vary the volume of the product tank.;COPYRIGHT: (C)2008,JPO&INPIT
