Apparatus for fluid distribution in a fluid-solids contacting chamber

Abstract

Abstract A FLUID DISTRIBUTING MEANS FOR USE IN FLUID-SOLIDS CONTACT CHAMBERS CONTAINING A PLURALITY OF FIXED BEDS OF PARTICULATED CONTACT SOLIDS. THE MEANS COMPRISES A PLURALITY OF FLUID DOWNCOMERS WHICH ENCOMPASS OPENINGS IN AN IMPERFORATE DECK PLATE AND RISE A FINITE DISTANCE ABOVE THE PLATE. THE DOWNCOMERS ARE PERFORATED TO PROVIDE GREATER OPEN AREA FOR FLUID FLOW WITH RESPECT TO INCREASING DISTANCE FROM THE FACE OF THE PLATE. A PREFERRED EMBODIMENT IS A DECK CONTAINING DOWNCOMER MEANS COMPRISING SCREEN MEANS HAVING SCREEN OPENINGS OF INCREASING DIMENSION WITH RESPECT TO INCREASING DISTANCE FROM THE DECK PLATE. A FURTHER PREFERRED EMBODIMENT IS A DECK CONTAINING DOWNCOMER MEANS COMPRISING TUBULAR SCREEN MEANS FORMED BY THE HELICAL WINDING OF A CONTINUOUS ROD MEMBER AROUND A PLURALITY OF SPACED LONGITUDINAL BAR MEMBERS TO PRODUCE A CONTINUOUS HELICAL SLOT OPENING OF CONTINUOUSLY INCREASING SLOT WIDTH.
