Abstract
Nanoparticles are synthesized by suctioning a liquid under a negative pressure with a negative-pressure suction force caused by the rotation of a rotary blade, causing cavitation by stirring the suctioned liquid by the rotary blade, generating plasma generated by a plasma generation mechanism in air bubbles generated in the liquid, and in that case, consuming an electrode containing elements constituting the nanoparticles to be synthesized.
Claims14
A nanoparticle synthesis apparatus comprising:
- a recirculation mechanism unit comprising:
- a gas release pipe configured to discharge a gas from the recirculation mechanism unit;
- a suction stirring pump comprising:
- a rotary blade configured to suction a liquid into the suction stirring pump and generate cavitation bubbles in the liquid by cavitation,
- a casing configured to encase the rotary blade;
- and
- a plasma generation mechanism connected between the recirculation mechanism unit and the casing,
- wherein the casing is connected between the recirculation mechanism unit and the plasma generation mechanism,
- wherein the suction stirring pump is configured to:
- suction, from the recirculation mechanism unit by rotation of the rotary blade, the liquid into the suction stirring pump, and
- generate, in the suction stirring pump by the rotation of the rotary blade, cavitation that produces the cavitation bubbles in the liquid,
- wherein the plasma generation mechanism is configured to:
- generate a plasma in the cavitation bubbles,
- receive, when the suction stirring pump causes the cavitation, the liquid from the suction stirring pump,
- generate, when the plasma generation mechanism receives the liquid from the suction stirring pump, the plasma in the cavitation bubbles, and
- supply, through the plasma generation mechanism when the plasma generation mechanism generates the plasma in the cavitation bubbles, the liquid to the recirculation mechanism unit, and
- wherein the recirculation mechanism unit is configured to:
- separate, when the recirculation mechanism unit receives the liquid from the plasma generation mechanism, the cavitation bubbles from the liquid,
- discharge, via the gas release pipe when the recirculation mechanism unit separates the cavitation bubbles from the liquid, the gas in the cavitation bubbles from within the recirculation mechanism unit, and
- supply, when the when the recirculation mechanism unit separates the cavitation bubbles from the liquid, the liquid to the suction stirring pump.
