Title:
NANOFLUID PRODUCTION APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2007/034912
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a nanofluid production apparatus which has a relatively
simple and inexpensive structure, can continuously and stably produce a nanofluid
in a large amount, and is easy to handle. It attains a considerable reduction in
production cost and enables nanofluids suitable for various applications to
be produced and selected. It can efficiently produce a nanofluid. [MEANS FOR
SOLVING PROBLEMS] The apparatus (1) for producing a nanofluid containing nanobubbles,
i.e., bubbles having a diameter smaller than 1 µm, comprises: a gas/liquid
mixing chamber (7) in which a liquid and a gas which have been fed are forcibly mixed
while causing turbulent flows therein; and a means (4) of pressurizing the gas
and liquid to be fed to the gas/liquid mixing chamber (7). The apparatus has an
ultrafine ejection opening (20) through which the fluid obtained by the gas/liquid
mixing is discharged outside in a pressurized state from the gas/liquid mixing
chamber (7) to yield a nanofluid. The apparatus further has a filtration mechanism
(F) which removes a nanofluid having a diameter not smaller than a given value
from the nanofluid yielded.
