<p>The air depollution device comprises a container (1) which has, at opposite ends, an intake grille (6) and an emission grille (7), both of which are suitable to convey a large stream of air. A mechanical filter (10) and an activated-charcoal filter (11) are arranged inside the container together with a collection device (12) which is arranged downstream of the two filters and has, in succession, an electrification grid (16) which is supplied with a high voltage of negative polarity and arranged on a plane (19) which is transverse to the container, a partition (18) arranged at an angle in front of the electrification grid so as to convey the stream of air toward at least one narrower region, a negatively charged deflector plate (20) and a positively charged collector plate (21) which face one another at a short distance so as to delimit the above-mentioned respective narrower region. A germicidal lamp (30), arranged at an opening (28) of the deflector plate, is suitable to illuminate the collector plate substantially along its entire length in a direction which is transverse to the container. Suction means (13) are suitable to create the stream of air inside the container. An ionizing element (32) is arranged at the outgoing stream of air. <IMAGE></p> |
