PURPOSE: To improve the diversity and efficiency of a gas-sparged hydrocyclone. CONSTITUTION: This hydrocyclone has a means for establishing a vortex action in a volume between the bottom (second end) 21 of the porous surface of a hollow main body and the second withdrawal means or outlet 23, to effect separation of some or substantially all of the remaining gases in the fluent material when it reaches the bottom 21 of the porous surface of revolution 18. The revolution means comprises a shroud means 25 disposed above a conical bottom (second end) section 24 (e.g. sharply tapered), a means 28 for forming the shroud means and the central axially extending passage 27 of the conical interior passage 30 of the shroud means 25. A gas separated in the conical bottom section 24 by the other revolution means is joined to a gas separated by a revolution flow 15 in the hollow main body and then discharged from a gas withdrawal conduit 14 at the top. High density and larger particles move toward the wall where they are extracted through a generally tangential outlet nozzle 35. The accepted slurry flows downwardly toward the outlet 23. |
