FILTERING ASSEMBLY AND FILTERING METHOD FOR AIR AND GASEOUS FLUIDS IN GENERAL

摘要

A filtering assembly for air and gaseous fluids in general is provided comprising a duct, which can be crossed by a gaseous fluid carrying pollutants. The filtering assembly comprises: at least one filtering station to remove toxic gases and solid particle pollutants of dimensions preferably greater than 50 μm; at least one conductive grille, having at least one hole which faces and is proximate to at least one conductive filament being kept at a negative electric potential for the emission of electrons, which can be paired with pollutants of the solid particles and micro-organisms type of dimensions preferably between 10 nm and 50 μm, at least one accumulation plate downstream of the grille, maintained at a positive electrical potential for the stable collection of pollutants paired with the electrons at least one emission source of ions, for the restoration of electric charge of the gaseous fluid, flowing over the source.

1. A filtering assembly for air and gaseous fluids in general, comprising a duct (2) that can be crossed by a gaseous fluid that carries pollutants of various kinds, wherein said filtering assembly comprises:
at least one filtering station, for removal of pollutants of the type of toxic gases and solid particles with dimensions preferably greater than 50 μm; at least one conducting grille (4), which has at least one hole (5) that faces and is proximate to at least one conducting filament (6), said at least one grille (4) and said at least one filament (6) being kept at a negative electric potential, for the emission of electrons, which can be paired with pollutants such as solid particles and micro-organisms, having dimensions preferably comprised between 10 nm and 50 μm, downstream of said grille (4) there being at least one accumulation plate (7), which is kept at a positive electric potential, for the stable collection of the pollutants paired with the electrons; at least one emission source of ions (A), for restoring the electrical charge of the gaseous fluid that flows over said source.
