Abstract

PROBLEM TO BE SOLVED: To provide a sono luminescence probe for measuring the intensity of a cavitation being generated in a liquid using ultrasonic waves by converting the intensity to light. SOLUTION: A sealed container 1 is constituted so that it passes ultrasonic waves but does not pass light, contains a gas such as air, an emission liquid 2 where a specific amount of luminol reagent is mixed is loaded, and a photo sensor 3 is placed in the sealed container 1 opposite to the emission liquid 2, thus constituting a sono luminescence probe 4. Further, a power meter 6 is connected to the photo sensor 3 of the sono luminescence probe 4 via a lead wire 5. In this case, ultrasonic waves pass through the emission liquid 2 and the photo sensor 3. However, by loading them into the sealed container 1 that does not pass light and dipping the sealed container 1 into a liquid where ultrasonic waves are applied, the emission liquid 2 emits light due to the acoustic chemical reaction in the emission liquid 2 in the sealed container due to applied ultrasonic waves. Therefore, by detecting an emission intensity using the photo sensor 3 and measuring the electrical output of the photo sensor 3 using a power meter 6, the ultrasonic intensity contributing to a chemical reaction can be easily measured and the correlation of the advance of the measurement intensity and chemical reaction can be obtained more easily.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sonoluminescence probe for measuring the intensity of cavitation generated in a liquid by ultrasonic waves by converting the intensity into light.

[0002]

2. Description of the Related Art Conventionally, the strength of cavitation is measured by a mechanical method of erosion of aluminum foil by ultrasonic waves and a chemical method of estimating the progress of chemical reaction by ultrasonic waves.

[0003]

However, accurate measurement is difficult with such a mechanical method by erosion of the aluminum foil, and accurate values are not obtained by the method of estimating from the progress of chemical reaction by ultrasonic waves. Although it can be obtained, there is a problem that the measurement takes time.

[0004]

According to the present invention, there is provided a sealed or open container which transmits ultrasonic waves and does not transmit light, a luminescent liquid containing at least one of air, a rare gas and a luminol reagent, and An optical sensor installed so as to face the liquid is placed in the container.

[0005]

According to the present invention, the ultrasonic wave passes through the luminescent liquid and the optical sensor, but is sealed in a sealed container that does not allow light to pass therethrough. The emitted ultrasonic waves cause the luminescent liquid to emit light by a sonochemical reaction in the luminescent liquid in the sealed container. If the luminescent intensity is detected by an optical sensor and the electrical output of the optical sensor is measured by a power meter, the chemical The intensity of the ultrasonic wave that contributes to the reaction can be easily measured, and the correlation between the measured intensity and the manner in which the chemical reaction proceeds can be more easily obtained.

[0006]

FIG. 1 is a side sectional view of a sonoluminescence probe according to an embodiment of the present invention. The sealed container 1 is configured so as to allow ultrasonic waves to pass therethrough but not light. A luminous liquid 2 containing a predetermined amount of a luminol reagent is contained therein, and a light sensor 3 is mounted in the sealed container 1 so as to face the luminous liquid 2 to form a sonoluminescence probe 4. A power meter 6 is connected to the optical sensor 3 of the sonoluminescence probe 4 via a lead wire 5.

The container 1 may be made of a material such as black resin, metal, glass, etc., which is hard to transmit light and transmits sound.

[0008] In this embodiment constructed as described above, FIG.
As shown in the figure, a liquid 9 is put into a container 8 having an ultrasonic vibrator 7 attached to the bottom, and the liquid 9 is irradiated with ultrasonic waves from the ultrasonic vibrator 7 to generate cavitation in the liquid 9. When the sonoluminescence probe is immersed in a state where it is in a closed state, the sealed container 1 does not pass through the surrounding light. 3 and converted into an electrical output, the electrical output is detected by the power meter 6, and the detected value corresponds to the intensity of light generated in the luminescent liquid 2, thereby reducing the intensity of cavitation. Can be detected.

Since it is considered that a rare gas other than air acts on the light emission, an argon gas may be used.
The amount of the luminol reagent can be added from 0% to a predetermined amount, if necessary. Further, when a predetermined amount of luminol is added to sonoluminescence at 0%, a luminol reaction occurs.

[0010]

As described above, according to the present invention, the sonoluminescence probe is immersed in a liquid in which cavitation is generated by irradiation of ultrasonic waves.
Cavitation is generated in the luminescent liquid in the sonoluminescence probe by the ultrasonic waves, and the cavitation causes a chemical reaction to proceed to generate luminescence in the luminescent liquid, thereby converting the intensity of the luminescence into an electrical output. Since the output is detected by the power meter, there is an advantage that the intensity of the ultrasonic wave contributing to the chemical reaction can be easily measured, and the correlation between the measured intensity and the progress of the chemical reaction can be obtained more easily.
