Abstract

The present invention relates to a nanoparticle production reactor. An aspect of the present invention provides a nanoparticle production reactor comprising: a main chamber including a first nozzle through which a raw gas is supplied; a lens housing which is connected to the main chamber to allow fluid to move therebetween and includes a second nozzle for supplying flushing gas thereinto; a lens mounted on the lens housing; a light source for emitting a laser such that the laser passes through the lens to reach a raw gas in the main chamber; and a hood for discharging a nanoparticle produced in the main chamber, wherein the lens housing is provided to have at least a partial region having a sectional area decreasing along a direction toward the main chamber.

Description

technical field [0001] The invention relates to a reactor for the production of nanoparticles. [0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2017-0114288 filed on September 7, 2017, the entire disclosure of which is incorporated herein by reference. Background technique [0003] In general, laser pyrolysis is a method of forming nanoparticles by irradiating a raw material with a laser to decompose the raw material. [0004] By using laser pyrolysis of silane gas (SiH 4 ) capable of synthesizing silicon nanoparticles. In such devices, it is important to have a good collection of the synthesized nanoparticles without loss in order to increase the productivity. [0005] The laser pyrolysis reaction equipment is equipped with an optical lens through which the laser beam passes. If the lens is contaminated by nanoparticles, the lens may be damaged. [0006] In order to prevent this, the lens is installed to be separated fro...
