The increase of diesel vehicle leads to a large amount of NO emissions, and non-thermal plasma (NTP) combined with wood fiber is a new method in the field of exhaust gas purification. In this paper, the effects of NTP combined with different kinds of wood fibers and without wood fibers on the removal of NO were compared, and the optimal purification efficiency of NO was determined by experiments under different application conditions. The experimental results show that the NO conversion efficiency of NTP combined with wood fiber is better than that of NTP or wood fiber alone, among which NTP combined with scotch pine has the highest conversion efficiency. Through the analysis of the mechanism of NO conversion by wood and NTP, the effects of different conditions on NO conversion were obtained. The trend of NO removal with voltage/frequency indicates that the increase of voltage and frequency can promote the removal of NO. The increase of humidity also promoted the removal of NO, but when the humidity exceeded 25%, the conversion of NO decreased slightly. And the filling rate of 0.3 is the best value for NO conversion. Although NO cannot be completely purified by this method, there is still a higher conversion efficiency under the condition of low temperature and no catalyst. It can be proved that NTP bonded wood fiber is a new way to remove NO.

NTP与木纤维的NO去除性能研究

柴油车的增加导致大量的NO排放，非热等离子体（NTP）结合木纤维是废气净化领域的一种新方法。本文比较了NTP结合不同种类木纤维和不含木纤维对NO的去除效果，并通过不同应用条件下的实验确定了NO的最佳净化效率。实验结果表明，NTP与木纤维结合的NO转化效率优于NTP或木纤维单独使用，其中NTP与苏格兰松结合的转化效率最高。通过对木材和NTP转化NO的机理进行分析，得到不同条件对NO转化的影响。NO 去除随电压/频率变化的趋势表明，电压和频率的增加可以促进 NO 的去除。湿度的增加也促进了NO的去除，但当湿度超过25%时，NO的转化率略有下降。而0.3的填充率是NO转化的最佳值。这种方法虽然不能完全净化NO，但在低温和无催化剂条件下仍有较高的转化效率。可以证明NTP结合木纤维是一种去除NO的新方法。这种方法虽然不能完全净化NO，但在低温和无催化剂条件下仍有较高的转化效率。可以证明NTP结合木纤维是一种去除NO的新方法。这种方法虽然不能完全净化NO，但在低温和无催化剂条件下仍有较高的转化效率。可以证明NTP结合木纤维是一种去除NO的新方法。
