Patent attributes
The present invention provides: a nanofluid generating apparatus that has relatively simple construction, is capable of stably generating nanobubbles, is easy to handle and makes it possible to reduce manufacturing cost; and a cleaning apparatus that uses nanofluid. An apparatus for generating nanofluid containing nanobubbles, wherein the nanobubbles are gas bubbles with diameter less than 1 μm, comprising: a gas-liquid mixing chamber 7 for mixing gas and liquid; and a pressurization pump 4 and an air intake valve 21 for supplying the pressurized gas and liquid to the gas-liquid mixing chamber, wherein the gas-liquid mixing chamber comprises therein:a turbulence generating means Z having projecting lines 9 and grooves 10, 12, and a conical section 11, for forcibly mixing the supplied gas and liquid by generating turbulence therein; and a nano-outlet 20 for turning the forcibly mixed gas and liquid mixture into nanofluid having nano bubbles and discharging the nanofluid.
