Abstract: A system for the purification of the particulate present in fumes and in exhaust gases in combustion processes comprises an Ionizing Part (PI) and a Collection Pan (PR). The Ionizing Part (PI) comprises a perforated portion (40, 50) with at least one electron emitter in the holes (42, 52), consisting of one or more tips (P) to which a negative voltage is applied to create an electron cloud. The negative power supply is provided by a constant voltage generator. The fumes and exhaust gases arc passed through the Ionizing Part (PI) to transfer a negative charge to the particles of the particulate present in the flow of fumes and exhaust gases. The Collection Part (PR) comprises a plurality of positively loaded facing and spaced plates (22b) interposed with a plurality of shield plates (20b) to which no voltage is applied and are not connected to ground, to collect the particles of particulate previously negatively charged.

Abstract: A system for the purification of the particulate present in fumes and in exhaust gases in combustion processes, comprising an Ionizing Part (PI) and a Collection Part (PR), wherein the Ionizing Part (PI) comprises a perforated portion (40, 50) with at least one electron emitter inside the holes (42, 52) consisting of one or more tips (P) to which a high negative voltage is applied to create an electron cloud, wherein said negative supply is provided by a constant voltage generator, in which the fumes and exhaust gases are passed through the Ionizing Part (PI) to transfer a negative charge to the particles of particulate present in the flow of the fumes and exhaust gases, and wherein the Collection Part (PR) comprises a plurality of metal pipes (20) positively charged to collect the particles of particulate previously negatively charged.

Abstract: A particulate filtration apparatus for exhaust, combustion or other gases includes an enclosure for the output of a flow of such gases, prior to their release into the outside environment. An internal duct crossed by the flow and affected by a perforated conducting plate is kept at a negative electrical potential, for emission and dispersion in the duct of electrons coupled to polluting particles carried by the flow and substantially constituting the particulate, consequently giving them a negative electrical charge. Along the duct downstream of the perforated plate is an accumulation plate, kept at a positive electrical potential, for the attraction and stable adhesion of the electrically charged particles on the accumulation plate. A conducting filament at a negative electrical potential adjacent at least one opening of the perforated plate is a primary source of emission and dispersion of electrons which are coupled to particles carried by the flow.

Abstract: The filter device for air purification has an electrification grid supplied with a high voltage of negative polarity and arranged on a plane transverse to an air flow for negatively charging particles present in the air. A partition is arranged at an angle in front of the electrification grid so as to convey the stream of air toward a narrower region. A negatively charged deflector plate and a positively charged collector plate, which face one another at a short distance, delimit a respective narrower region for respectively repelling and attracting the negatively charged particles. A germicidal lamp is arranged at an opening of the deflector plate and illuminates the collector plate substantially along its entire length in a direction which is transverse to the air flow.
