<p>[PROBLEMS] To provide a nanofluid generator which has a relatively simple constitution, can stably generate nanobubbles, is easy to handle, and can attain a reduction in production cost; and a cleaning apparatus employing a nanofluid. [MEANS FOR SOLVING PROBLEMS] The nanofluid generator, which generates a nanofluid containing nanobubbles which are bubbles having a diameter smaller than 1 µm, comprises a gas-liquid mixing chamber (7) where a gas is mixed with a liquid and a pressurizing pump (4) and a suction valve (21) which supply the liquid and gas in a pressurized state to the gas-liquid mixing chamber. The gas-liquid mixing chamber has: a turbulent flow generation mechanism (Z) which includes ridges (9), grooves (10) and (12), a conical member (11), etc. and is disposed in the gas-liquid mixing chamber and which causes a turbulent flow in the liquid and gas supplied to thereby forcedly mix them; and an ultrafine ejection opening (20) through which the mixture fluid formed by the forced mixing is ejected in the form of a nanofluid containing nanobubbles.</p> |
