本文针对某型船用柴油机排放的颗粒物，研制了一种静电-旋风复合式柴油机微粒过滤器。采用扫描迁移率粒度仪（SMPS）和低压冲击器（LPI）对船用四冲程发动机（1200 rpm，67.3kW）排气中颗粒物的粒度分布进行了测量。实验结果表明，颗粒物中粒径小于1 μm的颗粒占绝大部分，DPF可以有效地捕集发动机排气中粒径小于500 nm的细颗粒物。DPF对粒径小于200 nm的颗粒物有很高的捕集效率。
In this paper, an Electrostatic-Cyclone DPF (Diesel Particulate Filer) has been developed to reduce the Particulate Matter (PM) from a marine diesel engine. Size distribution of the PM in the exhaust gas of four-stroke marine engine (1200rpm, 67.3kw) was measured by a Scanning Mobility Particle Sizer (SMPS) and a Low Pressure Impactor (LPI). The experimental results demonstrate that particles of less than 1 μm in diameter account for a major portion of the PM and that the DPF can collect fine particles in the PM (not exceed 500nm in diameter) from the engine exhaust gas. The DPF shows high collection efficiency for particles under 200 nm in diameter.
