Design of diesel engine exhaust three-stage particulate-trap and noise-silence system based on centrifugal and static electricity technologies

This paper introduced a development of a diesel engine exhaust three-stage particulate-trap and noise-silence system based on centrifugal and static electricity technologies. This system separated particulate material from the exhaust stream by means of centrifugal that was formed through rotating exhaust stream and static electricity that was formed by a static electricity-generating unit, make it burned out by a infrared heater. Authors had designed a centrifugal and static electricity soot particulate trap device, the soot burning device and burning control device, and installed it on the engine frame and tested it. The results showed satisfactory effectiveness cleaning and silencing is achieved simultaneously.
