NTP电极结构对光催化去除室内HCHO的影响研究

STUDY ON THE EFFECT OF NTP ELECTRODE CONFIGURATION ON THE PHOTOCATALYTIC REMOVAL OF HCHO

为了提高室内污染物甲醛的去除效率,本文采用光催化技术协同低温等离子体(NTP)技术分析两种不同电极结构对室内甲醛去除效果,结果表明,线板式电极结构对污染物去除效果优于线管式电极结构,光催化技术与NTP技术相结合可明显提高污染物的去除效果,同时达到提高污染物处理量的目的。将光催化技术与NTP技术相结合是光催化技术实际应用的一个研究方向。

In order to improve the photocatalytic removal rate of formaldehyde （HCHO） in indoor air, this paper analyzes the effect of two electrode configurations on the removal of HCHO by combining photocatalysis and non-thermal plasma technology. The results show that the effect of the line-plate electrode configuration on the removal of HCHO is more preferable than that of the line-pipe configuration, and the removal rate of HCHO can be enhanced by combining photocatalysis and NTP technology, as a result, the air amount need to be cleaned can be improved. So the combination of photocatalysis and NTP techmology is an applying direction of photocatalytic technology for air purification.
