摘要 |
The invention concerns a device for high frequency treatment of a liquid, solid or gaseous product comprising at least one treatment inductance (2) enclosing a tubular conduit (1) designed to be passed through by a stream of the product to be treated, said inductance (2) being powered by a high-frequency generator (3) via coupling means (22, 24). The inductance (2) has non-contiguous windings and the high-frequency generator (3) comprises a single oscillator power tube (4) connected to the high voltage distribution line, an oscillatory circuit with distributed constant (15) whereof the characteristics L, C determine the oscillation frequency required from the generator, said oscillatory circuit (15) being connected to the oscillator tube (4) anode via an insulating capacitor (14) relative to the high voltage supply continuous component, the high voltage distribution line being connected to the tube (4) cathode (5) via an element (6, 17, 18) determining the voltage and the high frequency signal phase, forming part of a complex reaction circuit connected between the oscillatory circuit (15) and the oscillating lamp (4) cathode (5). |
