Abstract:
A particle separating apparatus for separating a stock solution containing particles into a concentrated solution having a high content of particles and a clear solution having a low content of particles, comprising:a stock solution supplier for supplying a stock solution into a main portion of the separating apparatus; a bubble generator for generating air bubbles to promote the separation of particles; a first separator for separating the stock solution into a first concentrated solution and a first clear solution according to a centrifugal force created by swirling the stock solution supplied from the stock solution supplier; a first discharge passage for discharging the first concentrated solution separated by the first separator to the outside; a filter provided inside the first separator for permitting the passage of the first clear solution and collecting the particles in the first clear solution; a second separator provided inside the filter for generating a gas-liquid mixed swirl of the air bubbles and the first clear solution at or near its center according to a static pressure difference created in its radial directions by swirling the first clear solution, and separating the first clear solution into a second concentrated solution and a second clear solution by the generated swirl; a second discharge passage for discharging the second concentrated solution separated by the second separator to the outside; and a clear solution guide passage for guiding the second clear solution to the outside.
