ABSTRACT:
This apparatus is used in industrial treatment processes for fluids constituted of several chemical components which must be perfectly homogenized before taking part in processes, when it is necessary to achieve saturation conditions closest to the stoichiometric conditions. This apparatus is suitable to generate ultrasonic waves of manifold frequencies depending on the viscosity of treated fluid and with its flux velocity inside a duct. The apparatus consists in an ultrasonic waves generator which sends treatment-waves in a duct, to homogenize the arriving fluid by means of a newly conceived transducer which, in the meantime, sends also a beam of controlling waves to detect the achieved homogeneity of treated fluid. Controlling waves are analyzed by binary circuits which accept or reject signals, maintaining or changing the balance between received signals and generated signals until the right frequency of waves is sent to treatment transducer to insure the proper homogenization of the fluid.
