Nanofluid Production Apparatus and Method
First Claim
1. An apparatus for generating nanofluid containing nanobubbles, wherein the nanobubbles are gas bubbles with diameter less than 1 μ
- m, comprising;
a gas-liquid mixing chamber, having;
a turbulence generating mechanism for forcibly mixing supplied gas and liquid by generating turbulence, and a nano-outlet for discharging the gas-liquid mixture fluid to outside of the gas-liquid mixing chamber to generate nanofluid;
a gas-liquid supply apparatus for supplying gas and liquid into the gas-liquid mixing chamber through a supply channel in communication with the gas-liquid mixing chamber;
a pressurization means for applying pressure to the gas and liquid to be supplied to the gas-liquid mixing chamber; and
a control section for controlling operations of the pressurization means and the gas-liquid supply apparatus,wherein the control section controls at least one of the gas-liquid supply apparatus and the pressurization means to switch between a nanofluid generation mode and a cleaning mode for sterilizing, disinfecting or cleaning (hereafter, collectively referred to as “
cleaning”
) the inside of the gas-liquid mixing chamber and channels in communication with the gas-liquid mixing chamber.

Abstract
The object of the invention is to provide an apparatus and a method for generating a large amount of nanofluid continuously and stably with a relatively simple, inexpensive and easy-to-use structure, and for efficiently performing an intra-apparatus cleaning operation to substantially reduce the nanofluid manufacturing cost.
A nanofluid generating apparatus 1 for generating nanofluid containing nanobubbles, wherein the nanobubbles are gas bubbles with diameter less than 1 μm, comprises a gas-liquid mixing chamber 7, comprising a turbulence generating mechanism for forcibly mixing supplied gas and liquid by generating turbulence, and a nano-outlet 20 for discharging the gas-liquid mixture fluid to outside of the gas-liquid mixing chamber to generate nanofluid; a gas-liquid supply apparatus 21, 23, . . . for supplying gas and liquid to the gas-liquid mixing chamber 7; a pressurization pump for applying pressure to the gas and liquid; and a control unit CR for controlling operations of the pressurization pump 4 and the gas-liquid supply apparatus. The control unit CR controls the gas-liquid supply apparatus and the pressurization pump 4 to switch between a nanofluid generation mode and a cleaning mode for cleaning the inside of the gas-liquid mixing chamber 7.
