  • Fluids contacting, tray opening, fluid dispersing assembly
    Patent number: 6270062
    Abstract: A fluids contacting and dispersing apparatus for a fluids contacting column is provided comprising a perforated cover plate, means for positioning the cover plate over a tray opening and securing it within the opening. Deflecting members span each perforation in the cover plate to prevent bleed fluid from shooting straight up and hitting the underside of the above tray. The deflecting members also provide a surface for dispersing lighter, finer bleed fluid flowing upwardly through the perforations over a central zone of the cover plate and into heavier fluid flowing across the tray in the path of the cover plate. The deflecting members direct lighter fluid into what would otherwise be a stagnant central zone of the cover plate. The cover plate is positioned over the tray opening by means of legs which are integral with the cover plate and are slidable within the tray opening.
