被动式室内空气净化产品甲醛净化效果研究
|
摘要
研究分析了吸附净化技术、光催化净化技术和生物质净化技术等被动式空气净化技术的基本原理,并随机选取市场上相关种类的产品进行甲醛24 h去除率检测。实验结果显示,所选取的3类产品中,光催化净化产品的整体净化效果最好,在紫外光持续照射条件下,平均去除率达到了89.2%。其次是生物质净化产品,平均去除率为72.4%,同时发现存在一些质量较差的生物质净化产品。吸附净化产品整体净化效果与前2者相比较差,其平均甲醛24 h去除率为60%,仍具有一定的净化效果,其净化效果主要受到材料性质和接触面积的影响。
In this study, the basic principle of passive air purification technology was analyzed. Furthermore, formaldehyde purification experiments were applied to randomly selected adsorption purification products, photocatalytic purification products and biomass purification products, which belong to passive air purification technology. The result showed that, under the condition of UV light, the photocatalytic purification products leaded to best results in the experiment with a formaldehyde removal rate of 89.2% in 24 hours. Followed by the biomass purification products, the average removal rate for 24 hours was 72.4%. And some biomass purification products with low formaldehyde removal rate were found in experiment. Compared with the other two kinds of products, the adsorption purification product has relatively poor formaldehyde purification efficiency.However, this kind of products still have a certain effect with an average formaldehyde purification rate of 60%. Therefore, it was concluded from the present study that the effect of adsorption purification products were mainly affected by the material properties and contact area.
