Abstract

The present invention relates to a reactor for nanoparticle production, and according to an aspect of the present invention, there is provided a reactor for nanoparticle production, comprising: a main chamber including a first nozzle to which a feed gas is supplied a first nozzle; a lens housing fluidly connected to the main chamber and comprising a second nozzle for supplying flushing gas therein; a lens mounted on the lens housing; a light source for illuminating a laser for passing the laser through the lens to reach the feedstock gas in the main chamber; and a cover for exhausting nanoparticles generated in the main chamber, wherein the lens housing is configured such that the cross-sectional area of ​​at least a portion of the region Decrease in the direction facing 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...
