In order to reduce the emissions of pollutants from diesel exhaust, a kind of exhaust purification technology by the combination of non‐thermal plasma (NTP) with Nano‐CeO₂ supported on the micro‐wood fiber filter is proposed, and a simulation test bench is designed to test the influence factors of purification efficiency. It can be seen from the simulation experiments, the purification efficiency for particulate matter (PM) and NO_x can be enhanced from 37 and 28% to 53 and 38% when the content of Nano‐CeO₂ is from 0 to 16.92 wt%. The test results also show that the purification efficiency of PM and NO_x increases with the rising of temperature between 40 and 160°C. Furthermore, when the mass of PM is no more than 30 mg, the purification efficiency of PM and NO_x increases with the rising of PM mass. At last, the experiment shows that when the input voltage is between 6 and 12 kV, the corresponding purification efficiency increases with the rising of voltage. Temperature 160°C, catalyst 16.92 wt%, input voltage 12 kV, and PM 30 mg are the best experimental conditions for this study, in which the corresponding purification of PM and NO_x is 66 and 53%, respectively. This can provide an experimental basis for the practical application of NTP and wood fiber filters in the field of exhaust gas purification.

通过将非热等离子体与负载在木纤维过滤器上的Nano-CeO2相结合来处理柴油机废气

为了减少柴油机废气中污染物的排放，提出了一种将非热等离子体（NTP）与微木纤维过滤器上支撑的Nano-CeO ₂相结合的废气净化技术，并建立了模拟试验台。用于测试纯化效率的影响因素。从模拟实验可以看出，当纳米CeO ₂的含量为0至16.92 wt％时，颗粒物（PM）和NO _x的净化效率可以从37％和28％提高到53％和38 ％。测试结果还表明，PM和NO _x的净化效率随着温度在40至160°C之间升高而增加。此外，当PM的质量不超过30mg时，PM和NO _x的净化效率随着PM质量的增加而增加。最后，实验表明，当输入电压在6至12 kV之间时，相应的净化效率随电压的升高而增加。温度160℃，催化剂16.92％（重量），输入电压12千伏，和PM 30毫克是用于本研究的最好的实验条件，其中PM和NO的对应纯化_X是66和53％之间。这可以为NTP和木纤维过滤器在废气净化领域的实际应用提供实验依据。
