Abstract
Il dispositivo a filtro per il disinquinamento dell'aria comprende una griglia di elettrizzazione alimentata ad alta tensione con polarità negativa, disposta su un piano trasversale ad un flusso dell'aria e atta a caricare negativamente le particelle presenti nell'aria stessa; una paratia disposta inclinata di fronte a detta griglia di elettrizzazione in maniera da convogliare il flusso dell'aria verso almeno una zona di sezione ristretta; una piastra di deflessione caricata negativamente e una piastra di raccolta caricata positivamente, disposte affacciate a breve distanza, in modo da delimitare una rispettiva succitata zona di sezione ristretta, e atte rispettivamente a respingere e ad attrarre dette particelle caricate negativamente; una lampada germicida disposta in corrispondenza di un'apertura di detta piastra di deflessione e atta a illuminare detta piastra di raccolta sostanzialmente per l'intera lunghezza, secondo una direzione trasversale al flusso dell'aria.
