ABSTRACT:
A fluids contacting and dispersing apparatus for a fluids contacting column is provided including a perforated cover plate, a device 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 legs which are integral with the cover plate and are slidable within the tray opening. The fluid contacting and dispersing apparatus may be in a fixed, fluid dispersing and contacting assembly or in a movable, valve assembly that is displaced upwardly by the lighter fluid. The valve of the assembly provides finer exchange over a greater active area to increase efficiency and lower energy requirements.
