本発明は管内を流通する気体又は液体に対し均一な超音
波を照射して処理斑をなくすようにした超音波処理装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic treatment device that eliminates treatment spots by irradiating uniform ultrasonic waves to gas or liquid flowing in a pipe.
従来装置においては処理すべき気体又は液体を流通する

。In conventional devices, a vibrator is attached to the wall of a pipe through which the gas or liquid to be treated flows, and ultrasonic waves are irradiated into the gas or liquid. It is carried out only on gas or liquid passing above,
There is a problem in that the gas or liquid that passes beyond the vibrating surface is not irradiated and uniform ultrasonic treatment cannot be performed.

In the drawing, 1 is a tube through which the gas or liquid to be treated flows, and 2 is a piezoelectric vibrator fitted midway through the inner surface of the tube through a damper material 3 so as to be perpendicular to the direction of flow of the gas or liquid. This vibrator is made of a piezoelectric magnetic plate made of lead zirconate titanate, etc., and has a large number of through holes 2a that allow gas or liquid to pass through in the thickness direction.

When a signal is applied between the electrodes 2b, 2b of the piezoelectric vibrator 2, the piezoelectric vibrator 2 is excited in the thickness or radial direction due to electromechanical coupling, and from the inner wall surface of each through hole 2a... A sound wave is irradiated, and the untreated gas or liquid is subjected to uniform ultrasonic waves while passing through these through holes 2a, and is subjected to a predetermined treatment. In the above embodiment, one piezoelectric vibrator having a large number of through holes was used, but as shown in FIG. Composite piezoelectric vibrators attached in series may also be used. As described above, the ultrasonic processing apparatus of the present invention includes a piezoelectric vibrator having a large number of through holes installed in a pipe through which gas or liquid flows, and allows the gas, body, or liquid to pass through the large number of through holes of the vibrator. With this structure, uniform processing without spots can be performed.
