Patent ID: 8273302

Claim:
A component separating device comprising: a flow channel; an acoustic wave generator for generating an acoustic wave in the flow channel; a first inlet channel which has an inlet for receiving a first solution containing solid particles and which introduces the first solution containing the solid particles into the flow channel; a density grade generator for forming a density grade of the solid particles in the first inlet channel as to form a higher-density region at which the solid particles are located locally at a higher density in the first solution; a second inlet channel for introducing a second solution into the flow channel, the second inlet channel being coupled with the first inlet channel at the flow channel; a plurality of first outlet channels for discharging the introduced first solution and the introduced second solution from the flow channel; and a second outlet channel connected to the first inlet channel, wherein the first inlet channel has a first side surface connected to the second inlet channel, and the second outlet channel is arranged to discharge a first portion of the first solution between the higher-density region and the first side surface of the first inlet channel from the first inlet channel.
