Research on Passive Control of Pressure Swing Adsorption System of Alternating Double Tank


Article Preview

This paper introduces a new double tank alternative PSA system structure and working principle, the system uses passive control, namely the use of fluid energy to achieve their double tank alternating work and avoid expensive and complex control systems, only two valves instead of the traditional 7-10 valves, greatly simplified the structure, improve system security and reliability. At the same time, the thesis also introduced shuttle-type three-way diffluence regulation valve structure and theory.
