Abstract
An ionising device is described comprising a tubular bulb of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two opposite longitudinal terminal ends and open, a tubular cathode engaged in the bulb, a tubular anode fitted onto the bulb, a pair of covers coupled to a relative end of said bulb so as to hermetically close it, and a conductive electrode comprising a stem extending into said bulb, and a plurality of conductive crowns which are fitted onto the stem at predetermined distances from each other and are suitable to exert an elastic compression on the tubular cathode against the inner surface of the bulb.
Claims13
Ionizing device (1) adapted to ionize a fluid for removing/breaking down from the fluid contaminating particles,
- characterized in comprising:
- a tubular bulb (2) made from an electrically insulating or a dielectric material, extending along a longitudinal reference axis (A) and presenting at least one longitudinal open terminal end (3)(4);
- a tubular cathode (9) inserted into the bulb (2),
- a tubular anode (10) fit onto the bulb (2),
- at least one cover (5) (6) coupled to the open terminal end (3)(4) of the bulb (2) so as to hermetically close the open terminal end (3)(4);
- a conducting electrode (11) comprising a stem (13) extending within said bulb (2) along said longitudinal reference axis (A) and a plurality of conductive crowns (12) fitted onto said stem (13) at pre-established distances one from another along said reference axis (A) and which are adapted to exert an elastic radial compression onto said tubular cathode (9) against the internal surface of said bulb (2) at a plurality of points axially distanced along said reference axis (A).
Method of producing an ionizing device characterized in comprising the following steps:
- providing a tubular bulb (2) made from an electrically insulating or a dielectric material, extending along a longitudinal reference axis (A) and having at least one longitudinal open terminal end (3)(4);
- engaging a tubular cathode (9) onto the internal surface of said bulb (2);
- fitting a tubular anode (10) onto the external surface of said bulb (2);
- provide a conducting electrode (11) which comprises a stem (13) and a plurality of conductive crowns (12), which are fit onto said stem (13) at pre-established distances one after the other along the longitudinal axis of said stem (13);
- positioning said conductive electrode (11) within said bulb (2) so as to arrange said conductive crowns (12) into contact with the internal surface of said tubular cathode (9) in such a manner so as to exert an elastic compression onto said tubular cathode (9) against the internal surface of said bulb (2) at a plurality of points axially distanced between one another along said axis (A),
- hermetically closing said at least one terminal end (3)(4) od said bulb (2) through a relative closing cover (5)(6).
