Nitrogen oxides ( ${\mathrm {NO}}_{x}$ ), sulfur oxides ( ${\mathrm {SO}}_{x}$ ), and particulate matter (PM) emitted by diesel engines, thermal power generation plants, and various industrial establishments have had unfavorable effects on the environment globally. Therefore, it is necessary to install aftertreatment systems on such combustors because the emissions cannot be treated for combustion improvement only. To establish NO _x /SO _x , and nanoparticle control technologies, herein, we propose a single-stage wet-type nonthermal plasma (NTP) reactor. To evaluate the performance of the proposed system, we conducted a laboratory-scale experiment with a mixture of NO _x , SO _x , and polystyrene particles. In this system, PM is collected in a water film by the electrostatic effect, NO is oxidized to NO ₂ by NTP, and NO ₂ and SO ₂ are absorbed into a water film on the inner wall of the reactor. We achieved almost complete and simultaneous removal of the pollutants, with a partial collection efficiency of more than 98% for the nanoparticles (diameter = 22–334 nm), removal efficiency of 98% for NO _x , and removal efficiency of 99% for SO _x . Furthermore, we proposed a method to treat the chemical components left in the water film to enable a self-sustaining technique. The technology allows for conserving in space and investment costs in exhaust gas aftertreatment facilities.

走向NO_X/所以_X 和使用单级湿式非热等离子体反应器的纳米粒子控制技术

氮氧化物 （ ${\mathrm {NO}}_{x}$ )、硫氧化物( ${\mathrm {SO}}_{x}$ )、柴油发动机、火力发电厂和各种工业设施排放的颗粒物 (PM) 对全球环境产生了不利影响。因此，有必要在这种燃烧器上安装后处理系统，因为排放物不能仅用于改善燃烧。建立NO _X /所以 _X 和纳米粒子控制技术，在此，我们提出了一种单级湿式非热等离子体 (NTP) 反应器。为了评估所提出系统的性能，我们用 NO 的混合物进行了实验室规模的实验 _X ， 所以 _X 和聚苯乙烯颗粒。在该系统中，PM通过静电效应被收集在水膜中，NO被NTP氧化成NO ₂，NO ₂和SO ₂被吸收到反应器内壁的水膜中。我们实现了污染物的几乎完全和同步去除，纳米颗粒（直径 = 22-334 nm）的部分收集效率超过 98%，NO 的去除效率达到 98% _X , 对 SO 的去除效率为 99% _X . 此外，我们提出了一种处理留在水膜中的化学成分的方法，以实现自我维持技术。该技术可以节省废气后处理设施的空间和投资成本。
