Abstract
The invention provides a process for producing microparticles, which process enables production of microparticles such as oxide microparticles by means of a simple apparatus at low cost and which is suitable for producing ITO powder, and an apparatus for producing the microparticles. In the process for producing microparticles, a raw material in the form of a liquid stream, liquid droplets, or powder is fed into a heat source; the formed product in the form of microparticles is captured by means of an atomized liquid fluid; and the microparticles in the form of slurry are collected through gas-liquid separation.
Claims16
A process for producing microparticles, characterized in that the process comprises feeding into a heat source a raw material in the form of a liquid stream, liquid droplets, or powder;
- capturing the formed product in the form of microparticles by means of an atomized liquid fluid;
- and collecting the microparticles in the form of slurry through gas-liquid separation.
An apparatus for producing microparticles, characterized in that the apparatus comprises
- an inlet for introducing, into the inside of the apparatus, a gas fluid and a product obtained through feeding a raw material in the form of a liquid flow, liquid droplets, or powder into a heat source;
- a fluid jetting means for jetting an atomized liquid fluid to the introduced product;
- a first gas-liquid separation means for subjecting, to gas-liquid separation, microparticles captured by the liquid fluid, to thereby form a slurry of the microparticles;
- and
- a first circulating means for returning a part of an atmosphere fluid containing microparticles that have not been captured by the liquid fluid to a position where the fluid jetting means is disposed.
