A particulate filtration apparatus, for exhaust gases, combustion gases and the like, comprising an enclosure (2) that can be arranged along a circuit (3) for the output of a flow of exhaust gases, combustion gases and the like, prior to their release into the outside environment. The enclosure (2) defines internally a duct (4) that can be crossed by the flow and is affected by a perforated conducting plate (5), kept at a negative electrical potential, for the emission and dispersion in the duct (4) of electrons that can be coupled to polluting particles (B) carried by the flow and substantially constituting the particulate, consequently giving them a negative electrical charge. Along the duct (4), downstream of the perforated plate (5), there is at least one accumulation plate (6), which is kept at a positive electrical potential, for the attraction and stable adhesion of the electrically charged particles (B) on the accumulation plate (6). The filtration apparatus comprises at least one conducting filament (7), which is kept at a negative electrical potential and faces and is proximate to at least one respective opening (8) of the perforated plate (5), in order to define a primary source of emission and dispersion of electrons, which can be coupled to the particles (B) carried by the how, substantially proximate to their crossing of the opening (8). |
