DIESEL EXHAUST AFTERTREATMENT DEVICE AND METHOD FOR REGENERATION OF DIESEL PARTICULATE FILTER USING THERE OF

摘要

The present invention relates to a diesel generator exhaust gas treatment device. According to the present invention, the diesel generator exhaust gas treatment device comprises a diesel particulate filter (DPF) for trapping particulate matter (PM) contained in exhaust gas. The DPF is divided into a plurality of unit areas. Each of the divided unit areas includes a pressure sensor to measure a differential pressure, and is independently regenerated by a heat source device in accordance with the differential pressure. By dividing the DPF uniformly into the areas and selectively combusting and regenerating the areas, regeneration time and a fuel consumption amount of the heat source device can be reduced, an entire surface area of the DPF can regenerated uniformly, and regeneration efficiency can be improved.
