PURPOSE:To surely burn particulates at the particulate receiving portions by providing incinerators at the bottom portions of the particulate receiving portions arranged so as to receive black smoke particulates attached/detached from dust containing gas flow passages by reverse washing. CONSTITUTION:Filters 104a, 104b respectively having dust containing gas flow passages 34 and cleaning gas flow passages 35 divided by means of furnace walls, introduction pipes 37a, 37b introducing dust containing gas into the dust containing gas flow passages 34, a reverse washing nozzle 108a generating intermittently a gas current flowing to the dust containing gas flow passages 34 from the cleaning gas flow passages 35 through furnace walls, and the particulate receiving portions 112a, 112b arranged so as to receive black smoke particulates attached/detached from the dust containing gas flow passages 34 by reverse washing, are arranged at the exhaust passage 102 of a diesel engine 101. Corpuscle incinerators 120a, 120b are connected to the bottom portions of particulate receiving portions 112a, 112b. As a result, the particulates are surely burned at the particulate receiving portions 112a, 112b, and an uncombustiable element in a particulates is continuously discharged as ash so that is does not accumulate. |
