摘要
针对洗涤除臭工艺,研究评价除臭剂效果的实验方法。主要利用大气采样器和大型气泡吸收管模拟除臭洗涤塔中的气液传质的动态过程。应用该实验方法,以硫化氢为代表性污染物,模拟评价植物型除臭剂在洗涤塔中的使用效果,并探索除臭剂浓度和处理气体停留时间等关键操作参数对除臭效果的影响。除臭剂效果评价实验结果得到了实际工程应用效果的验证,表明:该实验方法可针对特定恶臭污染物比较不同除臭剂的除臭效果,分析除臭剂浓度和处理气体停留时间对除臭效果的影响,从而为工程项目中除臭剂的选型和工艺参数优化提供参考依据。
The experimental method for evaluating the deodorization effect of deodorants applied in scrubber was studied. The dynamic process of gas-liquid mass transfer in the scrubber was simulated by using air sampler and bubble absorption tube as the main apparatus. With this method,taking H2S as the evaluation indicator,the effect of galenical deodorant in scrubber was simulated and evaluated. And the influence of the key operation parameters,such as deodorant concentration and gas residence time,on the deodorization effect was explored. The results were verified by practical engineering application. It showed that the experimental method could be applied to compare the effect of different deodorants for some specific pollutants and analyse the influence of deodorant concentration and gas residence time on the deodorization effect. Thus it can provide reference for choosing deodorant and optimizing technology parameters in engineering projects.
