Embodiment Construction

[0012] Figure 1A Device 10 for producing nanoparticles 30 is shown. Device 10 includes an atomizer 11 for atomizing one or more liquid feedstocks into droplets 31 in chamber 5 . The liquid feedstock is preferably atomized using a two-fluid atomizer 11, wherein one or more atomizing gases are supplied to the two-fluid atomizer 11 to atomize the liquid feedstock into droplets 31 . The formed droplets 31 are further guided to a flame 12 generated by means of fuel gas and oxidizing gas. The flame 12 is preferably provided by a two-fluid atomizer 11 , by providing the fuel gas and the oxidizing gas from the atomizer 11 , so that the droplets 31 and the flame 12 are formed in the same device. Fuel gas and / or oxidizing gas may also be used as atomizing gas to form droplets 31, or they may be provided independently of the atomizing gas. The droplets 31 enter the flame 12 in liquid form, and in the flame 12 the liquid feedstock is converted into nanoparticles 30, which may have a d...

Abstract

The present invention relates to an apparatus and method for electrically charging nanoparticles (30). The invention comprises atomizing one or more liquid starting materials into droplets (3), electrically charging the droplets (3) during or after the atomization and vaporizing the one or more liquid materials of the droplets (3) for generating the nanoparticles (30) from the liquid droplets (3) such that the electrical charge of the droplets (3) is transferred into the nanoparticles (30) for producing electrically charged nanoparticles (30).

Description

field of invention [0001] The invention relates to a device for charging nanoparticles, and in particular to a device according to the preamble of claim 1 . The invention also relates to a method for charging nanoparticles, and in particular to a method according to the preamble of claim 12 . Background of the invention [0002] Nanoparticles, i.e. particles with a size of 1 to 1000 nanometers, have found many important applications in industry, such as in the glass industry to create catalytic surfaces, self-cleaning and antibacterial products, glass staining, and Manufacturing of optical components such as optical fibers, etc. Being able to produce nanoparticles is an important factor for the viable use of these applications. Nanoparticles need to have relatively narrow size distribution (monodispersity), anti-agglomeration (anti-agglomeration), and homogeneity (homogeneity). The production of nanoparticles should be easily transferred from laboratory-scale to industria...
