Abstract
This study proposes a two-stage rapid pressure swing adsorption(rPSA)technology to achieve efficient recovery of hydrogen gas pro-duced as a byproduct in the photovoltaic industry.By employing a nine-tower triple equalization design,efficient electric actuator control,and in-telligent adaptive control technology,the rPSA technology significantly enhances the purity and recovery rate of hydrogen while reducing environ-mental pollution.After the first stage of PSA,the purity of hydrogen increased from33.7%to 80.5%,and further to 99.997%after the second stage,with a recovery rate maintained at 82%.Impurities such as CO2,CO,and O2 were reduced to the ppmv level,and the concentration of ni-trogen was reduced to below 50ppmv in the final product gas.The rPSA technology not only improves the purity and recovery rate of hydrogen but also effectively removes impurities,offering significant practical application value for the green development and energy efficiency enhancement of the photovoltaic industry.It aligns with national energy-saving and carbon reduction policies and promotes energy conservation and emission reduction in the industrial field.关键词
