ABSTRACT:
A back washing and regenerating apparatus for a diesel particulate filter, which can reliably, efficiently and instantly back wash particulate filters to regeneration in all zones which are not locally restricted. An impact air valve is positioned downstream of a particulate filter for blowing off particulates adhered to the particulate filter by an impact wave from the impact air valve into a particulate burning section and burning them off by the heat of a heater in the particulate burning section.
