Abstract
An ultrafine bubble generating apparatus and an ultrafine bubble generating method capable of efficiently generating an ultrafine bubble-containing liquid with high purity are provided. In order to this, a heating element provided in a liquid is caused to generate heat, and film boiling is made on an interface between the liquid and the heating element. A film boiling bubble is generated by the film boiling, and ultrafine bubbles are thus generated near the film boiling bubble.
Claims5
An ultrafine bubble generating method comprising:
- generating ultrafine bubbles smaller than 1.0 μm in diameter by causing a heating element provided in a liquid to generate heat, making film boiling on an interface between the liquid and the heating element, and generating a film boiling bubble;
- and
- collecting the liquid containing the ultrafine bubbles generated in the generating step.
An ultrafine bubble generating method, comprising:
- dissolving a predetermined gas component into a liquid;
- generating ultrafine bubbles smaller than 1.0 μm in diameter containing the predetermined gas component by causing a heating element provided in the liquid in which the gas component is dissolved in the dissolving step to generate heat, making film boiling on an interface between the liquid and the heating element, and generating a film boiling bubble;
- and
- collecting the liquid containing the ultrafine bubbles generated in the generating step.
