二氧化氮转化吸收的条件优化研究

Study on Conditions Optimization for Absorptionand Transformation of NO_2

随着我国经济的发展,能源消耗带来的环境污染也越来越严重,大气烟尘、酸雨、温室效应和臭氧层的破坏已成为危害人类生存的四大杀手。其中人为活动排放的NO_x是造成大气污染的重要根源。为寻求高效控制氮氧化物的方法,在实验室模拟氮氧化物废气对其进行吸收研究,考虑影响吸收的主要因素,采用正交设计法对其转化条件进行优化。结果表明:增加反应气体压力,加大吸收液填料填充度有利于气体高效吸收。

The environmental pollution caused by energy consumption is becoming more and more serious with our economic development.The air dust,acid rain,greenhouse effect and destruction of the ozone layer have become the four major killers that endanger the survival of the people.NO x emitted by human activities is an important source of air pollution.To find efficient control method for nitrogen oxides,the absorption of nitrogen oxide waste gas in the laboratory was simulated.Transfer conditions were optimized by orthogonal design method with NO2 materials for considering affected factors.The experimental results showed that the absorption rate for gas was improved dramatically by increasing reaction gas pressure and filled materials.
