Abstract
An ozone-generating element is disclosed which has a tube ozonizer (1), consisting essentially of an outer metal tube (3) forming one electrode, and of a glass tube (4) which is located coaxially therein and is spaced from it and the inner surface of which is provided with an electrically conductive layer (5) serving as the other electrode. Ozone is formed by pulse discharges with a passive, plate-like spark gap (12) with a defined response voltage serving as a switching element. The tube ozonizer (1) is fed by a low-frequency current source (7) via a high-voltage transformer (9), to the secondary winding (10) of which a storage capacitor (11) is connected. A series of embodiments is proposed, and in these part or all the constructional elements of the critical pulse circuit form a constructional unit with, or integrated into, the tube ozonizer (1). In this way, it is possible to produce pulse circuits of extremely low inductance which lead to up to a doubling of the total efficiency of ozone generation. By means of the highest integration stage which is considered especially advantageous, it becomes possible to convert conventional ozone generators fed with alternating current to pulse operation, without having to carry out expensive conversion and adaptation work, especially in terms of circuitry.
