    氧气构造typically usepressure swing adsorption(PSA) technology and are used very widely for oxygen provision in healthcare applications, especially where liquid or pressurized oxygen is too dangerous or inconvenient, such as in homes or in portable clinics. For other purposes there are also concentrators based onmembrane technology

    An oxygen concentrator takes in air and purifies it for use by people requiring medical oxygen due to low oxygen levels in their blood.[1]氧气浓缩器还用于在工业过程中提供经济的氧气来源,在该过程中,它们也被称为氧气发生器或oxygen generation plants。氧气浓缩器利用分子滤网to adsorb gases and operate on the principle ofrapid pressure swing adsorption大气zeolite矿物质,然后排出氮。因此,这种类型的吸附系统在功能上是一种氮洗涤器,使其他大气气体通过。这将氧气作为原发性气体剩下。PSA技术是一种可靠且经济的技术,用于中小型氧气产生,低温分离更适合于更高的体积,外部递送通常更适合小体积。[2]

    At high pressure, the porous zeolite吸附large quantities of nitrogen, due to its large surface area and chemical character. After the oxygen and other free components are collected the pressure drops which allows nitrogen to desorb.
