这项工作研究了应用旋转填充床 (RPB) 从气流中去除臭氧的可行性。通过 Fe2+ 溶液吸收进行臭氧去除实验，以检查不同操作变量（包括 RPB 速度、气体流速、液体流速和 Fe2+ 浓度）下的臭氧去除效率。 RPB的内半径为1.0cm，外半径为4.4cm，轴向高度为2.0cm。 RPB速度范围为300至1800rpm，提供3-98当量重力。实验结果表明，RPB速度提高了臭氧去除效率。此外，臭氧去除效率随着液体流量和Fe2+浓度的增加而增加，但随着气体流量的增加而降低。由于RPB可以降低臭氧传质阻力，因此RPB可以成为从废气流中去除臭氧的有效吸收器。
This work investigated the feasibility of applying the rotating packed bed (RPB) to the removal of ozone from gaseous streams. Ozone removal experiments were conducted by absorption with Fe2+solution to examine the ozone removal efficiency at various operating variables including RPB speed, gas flow rate, liquid flow rate and Fe2+concentration. The RPB has an inner radius of 1.0cm, outer radius of 4.4cm and an axial height of 2.0cm. The RPB speed ranged from 300 to 1800rpm, providing 3–98 equivalent gravitational force. Experimental results indicated that the RPB speed enhanced the ozone removal efficiency. In addition, the ozone removal efficiency appeared to increase with an increasing liquid flow rate and Fe2+concentration but decrease with an increasing gas flow rate. Owing to that the RPB could offer a reduction in the ozone mass transfer resistance, the RPB could be an effective absorber for the removal of ozone from waste gas streams.
