Apparatus and Method for Treating Slurries

摘要

There is provided a material treatment apparatus. The material treatment apparatus includes a first compartment. The first compartment includes an inlet for receiving supply of slurry material, and a first material conduction space for conducting flow of the supplied slurry material in a downwardly direction. A second compartment is also provided including a second material conduction space for receiving a first intermediate material of the supplied slurry material and conducting the first intermediate material in an upwardly direction. A baffle is provided for interfering with conducting of the supplied slurry material from the first material conduction space to the second material conduction space. A turbulent flow mitigation device is disposed within the first compartment and configured to, upon interaction with the supplied slurry material, to effect adjustment to the flow characteristics of the supplied slurry material to generate a downwardly flowing flow characteristic-adjusted slurry material, wherein the flow characteristics of the supplied slurry material are transformed from turbulent flow to laminar flow. The turbulent flow mitigation device is disposed, relative to the baffle, such that the baffle directs the downwardly flowing flow characteristic-adjusted slurry material to a space below the first baffle. The first material conducting space is fluidly coupled, below the baffle, to the second material conduction space, such that the first intermediate material fraction of the downwardly flowing flow characteristic-adjusted slurry material is conducted to the second material conduction space from below the baffle. A collection region is disposed below the first and second compartments for collecting a separated solids-comprising fraction that has separated, by gravity settling, from the supplied slurry material.
