摘要
针对工业中一些尾气中二甲苯的回收,用二甲苯液体对其进行吸收,利于环保。通过建立鼓泡模型,给出了在不同管径下,气泡形状因子,最大气泡直径,鼓泡频率,最大上升高度等的变化规律。研究表明:气泡的形状因子随喷嘴内径和雷诺数的增大而增大;最大气泡直径随喷嘴内径的增大几乎成线性增大;鼓泡频率随喷嘴内径的增大而明显减小;最大上升高度则随着喷嘴内径的增大而增大,但幅度较小。
In the recovery of xylene in tail gas in industry, xylene liquid was used to absorb it, which was benefit to environment. By establishing bubbling model, the dependence of shape factor, maximum diameter, bubbling frequency, and maximum ascending height were obtained in various nozzle diameters. The results showed that with an increase of nozzle diameter and Reynolds number, the shape factor increased. The maximum diameter increased almost linearly and the bubbling frequency decreased with the increase of nozzle diameter. With the increase of nozzle diameter, the maximum ascending height increased, but the amplitude was shorter.
