초록 ▼

The invention concerns a device enabling the gas bubbles present in a liquid composition to be dissolved. The device comprises a chamber (10) provided with an inlet orifice (11) through which the composition to be debubbled is introduced, and an outlet orifice (12) through which the debubbled composition is discharged, an ultrasonic transducer (13, 14, 15, 16, 17, 18, 19, 20), a power supply (21) for supplying the said transducer, the said power supply (21) being regulated in frequency and power at the same time.

Device enabling gas bubbles contained in a liquid composition to be dissolved, comprising: a) a chamber (10) provided with an inlet orifice (11) through which the composition to be debubbled is introduced, and an outlet orifice (12) through which the debubbled composition is discharged; b) an ultrasonic transducer (13, 14, 15, 16, 17, 18, 19, 20) inducing an alternating pressure field inside said chamber; c) a power supply (21) coupled to said ultrasonic transducer for providing terminals of said transducer with a voltage and a current having an adjustable frequency wherein the liquid composition, the chamber and the ultrasonic transducer have a series resonant frequency and a parallel resonant frequency; d) adjusting means for carrying out a preliminary adjustment of said frequency, said adjusting means having i) means for measuring the sign of the phase difference between the current and voltage at the terminals of the ultrasonic transducer, and ii) means for, depending on said sign, incrementing or decrementing a counter which controls accordingly said adjustable frequency of said power supply, said counter being incremented or decremented until said phase difference be within a predetermined range, wherein a preliminary adjusted frequency of said power supply is produced; and e) means for continuously regulating said power and said preliminary adjusted frequency of said power supply to match said series resonant frequency and to provide a continuous adaptation of the amplitude of said alternating pressure field, said preliminary adjusted frequency and said power being independently regulated.
