Abstract
A device produces fine bubbles that has a simple configuration and that is capable of generating fine bubbles. This fine bubble generation device includes: a porous body having continuous pores; a liquid supply section that supplies a liquid to the porous body and causes the liquid to circulate through the continuous pores; and a liquid discharge section for discharging liquid that has circulated through the continuous pores.
Claims8
A fine bubble generation method using a fine bubble generation device comprising a porous body having continuous pores, a liquid supply part which supplies a liquid to the porous body and causes the liquid to flow through the continuous pores, and a liquid discharge part which discharges the liquid caused to flow through the continuous pores, wherein
- an average flow diameter of the porous body as measured with a palm porometer is 5 μm to 50 μm, and
- the average flow diameter is an average of the pore diameters of a smallest part of the continuous pores in the porous body,
- the method comprising the steps of:
- supplying a liquid in which a gas is already dissolved to the porous body from the liquid supply part of the fine bubble generation device, and
- causing the supplied liquid to flow through the continuous pores of the porous body to obtain a liquid containing fine bubbles from the liquid discharge part, wherein
- the fine bubbles are derived from the gas during passage of the supplied liquid through the porous body, and
- the fine bubbles emerge from the porous body with an average particle diameter of less than 1 μm.
