Abstract
Liquid flow in a reaction processing vessel 10 is set to a spiral flow, a liquid A and B as an additional liquid containing an inorganic substance to be added is injected at a center-side position with respect to an inner surface of the reaction processing vessel 10 in a reaction field of the reaction processing vessel 10 so as to perform reaction processing.
Claims12
A method of manufacturing reaction agglomerated particles, the method comprising:
- setting a liquid flow in a reaction processing vessel to a spiral flow of a reaction liquid;
- extracting the reaction liquid from the processing vessel;
- returning the extracted reaction liquid to the reaction processing vessel;
- generating the spiral flow in the reaction processing vessel by introducing the returned reaction liquid along an inner peripheral surface of the reaction processing vessel;
- injecting an additional liquid containing an inorganic substance at a center-side position with respect to an inner surface of the reaction processing vessel so as to perform reaction processing for obtaining the reaction agglomerated particles.
