摘要
与现有的污染物解吸技术方法相比,颗粒床过滤器在建造和维护成本方面具有明显优势。通过在颗粒床层之间加入活性炭层,可以通过多层颗粒床协同去除 PM2.5和二氧化碳。在实验过程中,PM2.5 的平均过滤效率超过 95%,而二氧化碳的平均吸附效率超过 80%。在协同去除过程中,用活性炭替代多层床中的一层或多层,可带来双重好处:(1)防止 PM2.5 干扰活性炭对 CO2 的吸附;(2)活性炭床的内部孔隙比表面积优势还能在过滤 PM2.5 时提供辅助吸附效果。此外,颗粒床还具有良好的协同再生性能。因此,本研究介绍了一种协同分离 PM2.5 和 CO2 的新技术方法,为颗粒床过滤在协同吸收多种污染物方面的应用提供了参考。
Influence of Granular Bed Combination Characteristics on the Performance of PM2.5 and CO2 Synergistic Separation
In terms of construction and maintenance costs, granular bed filters offer notable advantages over existing pollutant desorption technology methods. Achieving synergistic removal of PM2.5 and CO2 through a multideck granular bed is possible by incorporating an activated carbon deck between the granular bed decks. During the experimental process, the average PM2.5 filtration efficiency exceeds 95%, while the average CO2 adsorption efficiency surpasses 80%. Substituting activated carbon for one or more decks within the multideck bed during the synergistic removal process offers the dual benefit: (1) preventing PM2.5 from interfering with CO2 adsorption by the activated carbon; (2) the internal pore specific surface area advantage of the activated carbon bed can also provide an auxiliary adsorption effect when filtering PM2.5. In addition, the granular bed showed a good synergistic regeneration performance. Consequently, this study introduces a new technological approach for the synergistic separation of PM2.5 and CO2, which informs the application of particulate bed filtration for the synergistic uptake of multiple pollutants.
