Acoustic concentration method and device and a reaction method

摘要

A method for concentrating materials in a liquid involves pouring the liquid into a material-containing receptacle and irradiating the liquid by acoustic waves so that a stationary flow pattern with different flow rate areas is formed in the receptacle. A concentration device and reaction method using such concentration are also provided.

主权项

1. A concentration method for the concentration of material in a liquid, the method comprising:
introducing a liquid into a vessel, the liquid comprising a material; radiating acoustic waves into the liquid such that a circular stationary flow pattern having regions of different flow speed arises in the vessel; and removing the material that collects in regions of said flow pattern having a flow speed close to or equal to zero.
