Abstract
The present invention relates to device and method for reducing soot particles. The device for reducing soot particles includes a first filter provided to an exhaust gas flow passage through which exhaust gas from a diesel engine flows to have a predetermined volume of a plurality of grains to be operated as a volumetric filtration system, and a second filter provided to a predetermined position of the second filter to be operated as a surface filtration system.
Claims9
A recyclable device for reducing soot particles from an exhaust gas of a diesel engine, said device comprising:
- a housing connected to a diesel engine, the housing including an inlet portion and an outlet portion;
- a first filter for serving as a volume filter, the first filter comprising a plurality of grains provided in the housing;
- and
- one or more a second filters for serving as a surface filter, the one or more second filters being micro-porous and provided within the plurality of grains of the first filter for allowing multiple exhaust gas flow pathways.
A method for reducing soot particles of an exhaust gas of a diesel engine, comprising the steps of:
- filtering the soot particles by volumetric filtration;
- filtering the soot particles by surface filtration;
- and
- burning the soot particles collected in the volumetric filtration step and the surface filtration step;
- wherein the volumetric filtration step and the surface filtration step are performed concurrently.
