Provided is an ultrafine bubble (UFB) generating apparatus and an UFB generating method capable of efficiently generating an UFB-containing liquid with high purity. To this end, the ultrafine bubble generating apparatus (1) includes a pre-processing unit (100, 200) that performs predetermined pre-processing on a liquid W and a generating unit (300) that generates ultrafine bubbles (11) in a liquid (W) on which the pre-processing is performed. The generating unit (300) generates the ultrafine bubbles (11) by causing a heating element (10), which is provided in the liquid (W) on which the pre-processing is performed, to generate heat to generate film boiling on an interface between the liquid and the heating element (10).
摘要:
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 (10) provided in a liquid (W) is caused to generate heat, and film boiling is made on an interface between the liquid (W) and the heating element (10). A film boiling bubble (13) is generated by the film boiling, and ultrafine bubbles (11) are thus generated near the film boiling bubble (13).
摘要:
In order to efficiently produce a liquid containing ultrafine bubbles of a desired gas, an ultrafine bubble-containing liquid producing apparatus (2000) includes a gas dissolving unit (800) that dissolves a predetermined gas into a liquid (W), and a UFB generating unit (1000) that generates ultrafine bubbles in the liquid (W) in which the predetermined gas is dissolved. A CPU (2001) performs control under a first condition in a case of causing the gas dissolving unit (800) to operate in a circulation route passing through the dissolving unit (800). The CPU (2001) performs control under a second condition different from the first condition in a case of causing the UFB generating unit (1000) to operate in a circulation route passing through the UFB generating unit (1000).
