| 中文摘要 |
| 以甲苯气体为例,研究低浓度有机污染物在活性炭固定床吸附器内受边流效应影响的吸附过程。结果表明,由于边流效应影响,吸附床层死层增加,吸附容量减少,对直径0.36m,高径比为2.5的固定床,固定床甲苯吸附量损失可达1.78kg,吸附层高度损失0.12m. |
| 英文摘要 |
| The paper deals with the experimental and theoretic study on the influence of the effect of maldistribution on adsorption process in an industrial scale fixed bed,the result shows that as the result of the effect of maldistribution the adsorption capacitate of the fixed bed is decreased.For a fixed bed with diameter of 0.36 m and a height of 1.2m,1.78kg decrease of the adsorption capacity can be reached and the reducing of adsorption zone should be 0.12m. |
