Abstract
An ultrasonic wave type bubble removing system for removing bubbles from a first liquid from which bubbles should be removed, by imparting ultrasonic wave vibration to the first liquid. A part of a liquid conduit is provided in an ultrasonic wave liquid tank which has an ultrasonic wave oscillator and is filled with an ultrasonic wave propagating liquid. An absolute pressure of 1.3 Kg/cm.sup.2 or higher is maintained applied inside the liquid conduit. Ultrasonic wave vibration generated by the ultrasonic wave oscillator is imparted to the first liquid which is continuously delivered without causing a vapor-liquid interface in the liquid pipe, to dissolve the bubbles in the first liquid and to prevent deposition of bubbles under the atmospheric pressure.

A method of ultrasonic wave type bubble removing for removing bubbles from a first liquid by imparting ultrasonic wave vibration to said first liquid, comprising the steps of:
- disposing a part of a liquid conduit in an ultrasonic wave liquid tank which is provided with an ultrasonic wave oscillator and is filled with an ultrasonic wave propagating liquid;
- delivering said first liquid through said part of said conduit without a vapor-liquid interface in said conduit and while maintaining an absolute pressure of 1.3 Kg/cm.sup.2 or higher inside side liquid conduit;
- and
- generating ultrasonic wave vibration by said ultrasonic wave oscillator and imparting said vibration to said first liquid in said liquid pipe to dissolve the bubbles in said first liquid and prevent deposition of bubbles under the atmospheric pressure.
In an ultrasonic wave type bubble removing device for removing bubbles from a first liquid by imparting ultrasonic wave vibration to said first liquid, the improvement comprising;
- (a) a tank for preparing and storing said first liquid;
- (b) a liquid conduit having its one end coupled to said tank and its other end communicating with a liquid delivering section under the atmospheric pressure;
- (c) pressurizing and liquid delivering means for continuously delivering said first liquid through said liquid conduit while maintaining an absolute pressure of 1.3 Kg/cm.sup.2 or higher inside said liquid pipe;
- and
- (d) an ultrasonic wave liquid tank provided with an ultrasonic wave oscillator and containing an ultrasonic wave propagating liquid and through which a part of said liquid conduit passes.
