Floating beads in fly ash have good industrial reutilization value. The conventional wet separation method for floating beads sorting consumes a large amount of purification solvent

leading to higher costs. Against this problem

this article proposes a method

in which the ash gas mixture is fed at the bottom of the cyclone separator

and the auxiliary wind is fed at the top to form a cyclone separator

thus to enrich the floating beads. Moreover

the Euler-Lagrange model is used to perform numerical simulation on the gas-solid two-phase flow in the enrichment device to verify the feasibility of the method. The influences of the height of the core tube

the incident speed of the bottom ash gas mixture and the feed speed of the upper auxiliary air on the enrichment effect are studied. The results show that

when the incident speed of the bottom gas mixture is 7.5 m/s

the core tube height is 3 000 mm

and the upper auxiliary air feed speed is 3.0 m/s

the mass fraction of the enriched floating beads increases by 45%. This method has obvious effects in improving the mass fraction of floating beads before wet sorting and reducing the cost of wet sorting.
