AN ULTRASOUND DEVICE

摘要

An ultrasound device is provided for treating a pumpable or flowable medium. The device includes a treatment vessel which is comprised of a hollow longitudinal member having an entrance aperture and an exit aperture for transporting a pumpable or flowable medium there-through. At least three transducer attachment cavities are provided for in a sidewall of the hollow longitudinal member. The device further includes an acoustic transducer mounted in each of the cavities such that each of the acoustic transducers is operable to be driven at a frequency and an amplitude to impart energy into the pumpable or flowable medium and to produce cavitation within the pumpable or flowable medium in the treatment vessel. The transducer attachment cavities in the sidewall of the hollow longitudinal member and hence the respective transducers are distributed in a helical path around an axial length of the hollow longitudinal member.
