Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
199 words
An apparatus for treating and homogenizing fluids constituted of several chemical components, by means of ultrasonic waves, comprising a generator of ultrasonic waves, a duct for passing therein a fluid to be treated, a transducer in said duct connected to said generator for emitting said ultrasonic waves in said duct and treating said fluid flowing inside said duct, a receiver in said duct facing said transducer for detecting waves passed through the fluid flowing inside the duct and emitting a detection signal, said generator being of the type generating a unique ultrasonic signal for treating the fluid and controlling the frequency of said ultrasonic signal according to the viscosity and/or the flow rate of the fluid to be treated, said transducer having a single bulb body protruding within said duct and having two openings for emitting two separate beams of said ultrasonic waves generated by said generator, said duct defining a first treatment zone where a first beam of ultrasonic waves performs a treating and homogenizing action on the fluid flowing inside the duct and a second zone, downstream said first zone, where a second beam is received from said receiver for controlling the homogeneity of the treated fluid.
Claim 2
Independent Claim
199 words
An apparatus for treating and homogenizing fluids constituted of several chemical components, by means of ultrasonic waves, comprising a generator of ultrasonic waves, a duct for passing therein a fluid to be treated, a transducer in said duct connected to said generator for emitting said ultrasonic waves in said duct and treating said fluid flowing inside said duct, a receiver in said duct facing said transducer for detecting waves passed through the fluid flowing inside the duct and emitting a detection signal, said generator being of the type generating a unique ultrasonic signal for treating the fluid and controlling the frequency of said ultrasonic signal according to the viscosity and/or the flow rate of the fluid to be treated, said transducer having a single bulb body protruding within said duct and having two openings for emitting two separate beams of said ultrasonic waves generated by said generator, said duct defining a first treatment zone where a first beam of ultrasonic waves performs a treating and homogenizing action on the fluid flowing inside the duct and a second zone, downstream said first zone, where a second beam is received from said receiver for controlling the homogeneity of the treated fluid.
Claim 3
Dependent Claim
46 words
An apparatus according to claim 1, comprising a shield arranged in said duct interposed in the path of said second beam and reflecting said second beam towards said receiver with a different reflection angle varying in accordance with the flow rate and/or viscosity of the fluid.
Claim 4
Dependent Claim
88 words
An apparatus according to claim 1, comprising a signal analyzer, a first and a second cable connecting said receiver and said generator to said signal analyzer, said signal analyzer including a binary circuit system receiving said detection signal from said receiver and, on the basis of the purity of the detection signal, accepting or rejecting it, maintaining or changing balance between said detection signal and said ultrasonic signal emitted by the generator for reaching the most suitable wave frequency required for the proper homogenizing treatment in real time.
