Fluids contacting, tray opening, fluid dispersing assembly

A fluids contacting column, tray opening, fluid dispersing apparatus, comprising:

• a cover plate for the tray opening, said cover plate containing at least one bleed fluid perforation;
• means for positioning the cover plate over the tray opening thereby, in operation, providing fluid escape passages between the cover plate and a tray deck for a fluid stream flowing upwardly through the tray opening;
• for the at least one bleed fluid perforation, a bleed fluid deflecting member spanning the bleed fluid perforation from side-to-side to provide at least two oppositely facing outlets such that at least two distinct bleed fluid streams flow away from one another over a central zone of the cover plate;
• and
• each said distinct bleed fluid stream differs in size from the fluid stream flowing upwardly through the fluid escape passages,
• wherein said bleed fluid deflecting member is a hump bridge over the bleed fluid perforation, wherein said hump bridge is a portion of the cover plate which has been formed by providing pairs of parallel slits in the cover plate and upwardly pressing the portion of the cover plate between the slits to provide the perforation therebelow leading to oppositely facing outlets on each side thereof.

• each said distinct bleed fluid stream differs in size from the fluid stream flowing upwardly through the fluid escape passages, wherein two bleed fluid perforations are provided on said cover plate such that each bleed fluid perforation has a bleed fluid deflecting member to form two distinct bleed fluid streams flowing away from one another over a central zone of the cover plate for each respective bleed fluid perforation.

A method of increasing the efficiency of and providing a greater effective active area for fluid interaction in a mass transfer exchange system, said method comprising:

• providing a valve assembly having a cover plate and means to position the cover plate over a tray opening in a tray deck of said mass transfer exchange system to define a fluid escape passage between the cover plate and the tray deck, wherein said means for positioning the cover plate over the tray opening is by integral and fixed legs attached to the cover plate and the tray deck;
• perforating said cover plate of the valve assembly to form at least one bleed fluid perforation in the cover plate;
• forming an integral deflecting member over said bleed fluid perforation which is substantially and geometrically identical to its respective bleed fluid perforation such that a finer fluid flow is dispersed through the bleed fluid perforation than a fluid flow through the fluid escape passage;
• and
• dispersing and directing said finer fluid flow toward a central portion of said cover plate.
