Abstract
An ionizing device is described, comprising a tubular bulb made of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two longitudinal open ends and opposite each other, a tubular cathode engaged in the bulb, a tubular anode fitted to the bulb, a pair of covers, each of which has a respective internal seat into which a respective end of the bulb is inserted so as to hermetically seal it, and a conductive electrode which extends into the bulb and is electrically connected to the cathode.
Claims11
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 two opposing longitudinal open terminal ends (3) and (4);
- a tubular cathode (9) inserted into the bulb (2);
- a tubular anode (10) fit onto the bulb (2);
- a pair of covers (5) (6), each of which is provided with a respective internal seat (7) (8) in which a relative terminal end (3) (4) of said bulb (2) is inserted so as to hermetically close the respective terminal end (3)(4);
- a conducting electrode (11), which extends within said bulb (2) and which is electrically connected to said cathode (9);
- and
- wherein the conducting electrode (11) is designed to mechanically connect said covers (5)(6) with one another and to exert a compression of said covers (5) (6) along the longitudinal axis (A) against said terminal ends (3)(4) of said bulb (2) for hermetically closing these terminal ends (3)(4).
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 two opposite longitudinal open terminal ends (3) and (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);
- positioning an electrical conductor (11) into said bulb (2) in such a manner to put it into contact with said tubular cathode (9);
- hermetically closing the open terminal ends (3) (4) through two respective closing covers (5)(6);
- and
- mechanically connecting said covers (5)(6) to one another through said conducting electrode (11) so as to exert a compression on said covers (5)(6) along the longitudinal reference axis (A) against said terminal ends (3)(4) of said bulb (2) in such a manner to hermetically close the open terminal ends (3)(4).
