Abstract:
Apparatus for removing agglomerates from a slurry comprising a transport fluid, a desired particulate matter, and undesirable agglomerates of the particulate material, said apparatus comprising:a flow control unit including a slurry inlet and a slurry outlet disposed substantially vertically above said slurry inlet, said flow control unit having an increasing cross sectional area in the vertical direction for providing a flow passage for the flow of the slurry from said slurry inlet to said slurry outlet, wherein the rate of increase of cross sectional area from said slurry inlet to said slurry outlet is substantially uniform for reducing turbulence due to the change in the cross section from the slurry inlet to the slurry outlet and wherein the velocity of the slurry in a horizontal cross section through said flow passage is substantially uniform across said cross section;an agglomerate removal unit, said agglomerate removal unit receiving the slurry from said slurry outlet and including an agglomerate removal screen unit through which the slurry is directed for separation of the agglomerates from the slurry;wherein the slurry enters said flow control unit through said slurry inlet having a first velocity and exits said flow control unit through said slurry outlet having a second velocity, wherein said first velocity is more than said second velocity.
