| 摘要: |
| 为解决室内氧含量不足的问题,提出一种基于中空纤维膜的富氧供氧系统模型。采用微元方法建立中空纤维膜分离空气过程数学模型并与实验数据进行对比,结果显示其平均误差不超过15%,表明膜分离模型具有一定可靠性。然后设计一种含有中空纤维膜组件与空气压缩机的富氧供氧稳态系统,分析压缩机压比和房间管道回风氧体积分数的设定值对空气压缩机的功耗与体积的影响。结果表明:减小膜组件入口压力虽然可以减小压缩机的功耗,但是体积并不会减小,因此,需要选择功耗与体积都相对较小的膜组件入口压力,适宜压力为200 kPa；房间管道回风氧体积分数设定值的增加会使压缩机的功耗和体积均增大,当管道回风氧体积分数为21%时,压缩机功耗与体积最小。基于研究结果可以为供氧系统中空纤维膜选择最优的工作参数。 |

| Abstract: |
| A model of an oxygen-rich supply system based on hollow fiber membrane is proposed to solve the problem of insufficient indoor oxygen content. A mathematical model of air separation process using hollow fiber membrane is established using the microelement method and compared with experimental data, showing an average error of less then 15%, indicating the reliability of the membrane separation model. Then, a steady-state oxygen-enriched supply system containing hollow fiber membrane components and an air compressor is designed to analyze the effects of compressor pressure ratio and room pipeline return air oxygen concentration setting values on the power consumption and volume of the air compressor. The results indicate that although reducing the inlet pressure of the membrane module can reduce the power consumption of the compressor; however, it does not reduce the volume. Therefore, it is necessary to select a membrane module inlet pressure with relatively low power consumption and volume, with the optimal pressure being 200 kPa. The increase in the target value of oxygen concentration in the room's pipeline return air will increase the power consumption and volume of the compressor. When the oxygen volume fraction of the room return air is set at 21%, the compressor exhibits the lowest power consumption and volume. Based on the research results, the optimal working parameters can be selected for hollow fiber membranes in oxygen supply systems. |
