这项工作检验了 H2O2 溶液在旋转填充床 (RPB) 中吸收臭氧 (O3) 的可行性。 O3 去除效率是根据不同的操作变量确定的，包括三个 RPB 中的 RPB 速度、气体流速和液体流速。对于每个 RPB，结果表明 RPB 速度对 O3 去除效率有积极影响。此外，O3 去除效率随着液体流量的增加而增加，但随着气体流量的增加而减少。此外，获得的结果表明，随着床内半径的增加和床外半径的减小，O3去除效率增加。此外，所开发的使用H2O2溶液吸收O3的方法可以提供超过95%的去除效率。因此，该新方法在去除废气中的 O3 方面具有巨大的潜力。
This work examined the feasibility of ozone (O3) absorption by H2O2solution in a rotating packed bed (RPB). The O3removal efficiency was determined at various operating variables including RPB speed, gas flow rate, and liquid flow rate in three RPBs. For each RPB, the results demonstrated that the RPB speed positively affected the O3removal efficiency. Also, the O3removal efficiency increased with the liquid flow rate but decreased with the gas flow rate. Moreover, the obtained results indicated that the O3removal efficiency increased as the inner radius of the bed was increased and the outer radius of the bed was decreased. Furthermore, the developed method for O3absorption using H2O2solution could provide the removal efficiency of more than 95%. Consequently, the novel method would have a great potential in the removal of O3from the exhausted gases.
