中文摘要：
建立了NTP喷射系统再生泡沫陶瓷PM吸附体的试验系统,以氧气为气源,研究了当温控区域温度和氧气流量不同时,NTP发生器产生的活性物质再生泡沫陶瓷PM吸附体的规律.结果表明：当氧气流量保持不变时,PM吸附体的再生时间随温控区域温度的升高呈先缩短后延长的趋势,当温控区域的温度为225 ℃时,再生时间较短;当温控区域的温度保持不变时,PM吸附体的再生时间随氧气流量的增加呈先缩短后延长的趋势,当氧气流量为4 L·min^-1时,PM吸附体的再生效果较好;间接低温等离子体技术可以在较低温度下有效去除PM,实现PM吸附体的离线再生,为NTP喷射系统高效再生DPF提供理论和试验依据.
英文摘要：
The experiment system of regenerating ceramic foam adsorbate （CFA） was established based on NTP injection.The active substance of CFA produced by the NTP reactor was investigated at different temperatures of the control area and O2 flow rates.The experimental results indicate that for constant O2 flow rate,the regeneration time of CFA is decreased at first and then increased with the increase of the control area temperature to obtain optimum temperature of 225 ℃.For invariable temperature of the control area,the regeneration time of CFA is decreased at first and then increased with the increase of O2 flow rate to give optimum flow of 4 L · min^-1 The NTP technology can effectively remove PM and regenerate CFA at low temperature of the control area.The results provide the basis for regenerating diesel particulate filter based on indirect non-thermal plasma system.
