Integrated suction hood featuring air depollution

In an integrated suction hood, an air depollution apparatus comprising:

• a container being connected to an intake grille in a downward region thereof and to a discharge grille in an upward region thereof;
• a mechanical filter and an activated-charcoal filter, said mechanical and activated-charcoal filters being mounted side by side on a frame that is inserted inside said container, above said intake grille, said frame being extractable from, and along a horizontal plane that lies transversely to said container;
• suction means being arranged above said extractable frame, said suction means being adapted to produce a flow of air inside said container;
• a collection device being arranged above said suction means, said collection device including, in succession, an electrification grid being supplied at a high voltage with negative polarity and arranged on a further horizontal plane lying transversely to said container, a partition being arranged at an angle in front of said electrification grid so as to convey the flow of air toward at least one region having a narrower cross-section, a negatively-charged deflector plate and a positively-charged collector plate, said deflector and collector plates being arranged vertically so as to face each other at a short distance for delimiting said region having a narrower cross-section;
• and a germicidal lamp being arranged at an opening of said deflector plate, said lamp illuminating said collector plate substantially over its entire length, along a horizontal direction.
