摘要

利用自行设计并搭建的流态化颗粒吸附性能实验台

对SiO

吸附甲醛和NO的特性进行了实验研究。结果显示:在无氧干态流动条件下

SiO

颗粒能够吸附空气中的甲醛和NO; 在实验条件(20～60 ℃)下

随着温度的升高

SiO

颗粒对甲醛的吸附能力增大

对NO的吸附能力增加不明显

说明对于不同的吸附质

SiO

颗粒表面的吸附规律及吸附机理均不同; 系统的循环流量对SiO

颗粒吸附甲醛及NO的能力影响不大; SiO

颗粒对甲醛的吸附能力高于对NO的吸附能力; 颗粒堆积可导致单位质量颗粒物对甲醛及NO的吸附能力下降。

Abstract

On a self-designed fluidized adsorption bench

adsorption characteristics of SiO

particles for formaldehyde and NO are investigated experimentally. The results show that in oxygen-free and dry condition

SiO

particles are able to adsorb formaldehyde and NO. Within the range of temperature from 20 to 60 ℃

the absorption capacity of SiO

particles for formaldehyde is increased with temperature while that for NO is almost unchanged

indicating the adsorption rule and mechanism for these two pollutants are different. The circular flow rate of the particles exerts a slight influence on adsorption for formaldehyde and NO. In the experimental condition the adsorption capacity of SiO

for formaldehyde is greater than that for NO. Particles accumulation usually we

akens the adsorption capacity of SiO
