Development of Super Economical and Compact Marine Diesel EmissionControl using Integrated Plasma Combined Processes

传统的静电除尘器很难收集船用柴油机产生的低阻微粒。为了抑制颗粒再夹带，研制了电流体动力辅助静电除尘器（EHD ESP）。研究了一种由吸附-解吸-非热氮等离子体组成的诺氏NOx还原体系。此外，等离子体ESP，它能够在同一单元内收集和焚烧颗粒。此外，还开发了用于PM还原的活性物质注入和NOx再循环EGR系统。将这些技术整合在一起，可实现90%以上的PM和NOx减排，从而实现极其经济和紧凑的船用发动机排放控制。

The collection of low resistive particulates generated from marine diesel engine had been known to be difficult using the conventional electrostatic precipitators. The electrohydrodynamically-assisted electrostatic precipitator (EHD ESP) was developed to suppress the particle reentrainment. A nobel NOx reduction system, which consists of adsorption, desorption, followed by nonthermal nitrogen plasma was developed. In addition, the plasma ESP, which is able to collect and incinerate particles within the same unit. Furthermore, reactive species injection for PM reduction and NOx recirculation EGR system were developed. Those technologies were integrated to achieve more than 90% PM and NOx reduction, leading to extremely economical and compact marineengine emission control.
