ABSTRACT:
A liquid jet manifold arrangement for process separator vessels for removing solids such as sand and sediment which accumulate along the bottom wall of the vessel during operation. A plurality of elongated manifolds are arranged to extend longitudinally along the vessel bottom wall and each manifold is provided with an array of jet nozzles which are arranged along the manifold bottom side and top side, respectively. The nozzles extend in a direction such as to create a substantially vortical flow of liquid to entrain and urge the fluidized solids mixture toward the solid removal outlet opening in the vessel. The manifolds are supported in a standoff position from the vessel bottom wall by adjustable support brackets and a generally arcuate shield is supported above and spaced from each of the jet manifolds to redirect the liquid flow out of the nozzles to enhance the vortical flow pattern.
