Title
(EN) ELECTRONIC PURIFICATION OF AIR IN MINES
(FR) PURIFICATION ÉLECTRONIQUE D'AIR DANS LES MINES
Abstract
(EN)
An emitter (23) to deliver an electron flow towards particulate matter, the emitter (23) including: a base (25); a conductive track (28) fixed to the base (25); a plurality of conductive pins (29) fixed to the base (25) and extending therefrom in a predetermined direction and electrically coupled to the track (28) so as to receive a negative electric charge therefrom; and a plurality of tubes (31), fixed to the base (25), and extending therefrom in said direction, with each of the tubes (31) having an interior extending away from the base (25) to an open end, with each tube (31) having at least one of the pins (29) located in the interior thereof.
