摘　　要：针对光电行业生产中产生的含氢副产品,提出了两级快速变压吸附技术(rPSA),以实现氢气的高效回收。通过九塔三均压设计、高效电力驱动控制和智能自适应控制技术,rPSA技术显著提升了氢气纯度和回收率,同时降低了环境污染。一级PSA后,氢气体积分数从33.7%增至80.5%;二级PSA进一步提升至99.997%,回收率维持在82%。杂质,如CO_(2)、CO和O_(2)的体积分数降至10-6级别,氮气体积分数在最终产品气中降至50×10^(-6)以下。rPSA技术不仅提高了氢气的纯度和回收率,而且有效去除了杂质,对光电行业的绿色发展和能源效率提升具有重要的实际应用价值,符合国家节能降碳政策,推动工业领域节能减排。This study proposes a two-stage rapid pressure swing adsorption(rPSA)technology to achieve efficient recovery of hydrogen gas produced as a byproduct in the photovoltaic industry.By employing a nine-tower triple equalization design,efficient electric actuator control,and intelligent adaptive control technology,the rPSA technology significantly enhances the purity and recovery rate of hydrogen while reducing environmental pollution.After the first stage of PSA,the purity of hydrogen increased from 33.7% to 80.5%,and further to 99.997% after the second stage,with a recovery rate maintained at 82%.Impurities such as CO_(2),CO,and O_(2)were reduced to the ppmv level,and the concentration of nitrogen 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.
