Abstract
An improved wet scrubber tray provides increased resistance to vibration-induced cracking. The self-supporting tray eliminates wastage of raw material, and additional internal stiffeners added to the tray make multiple intermediate stiffeners. The connection of the intermediate stiffeners to the perforated bottom plate is changed to eliminate the shop weld in the bottom plate. The holes in the perforated bottom plate are moved away from the boundaries of the tray to reduce their influence on boundary conditions. Trays are held down by plate material that is attached to the support grid, but not to the trays. Three field welds are applied to the sides of each tray to hold the trays in place relative to each other and are strategically placed to allow adjacent side stiffeners to act together as a composite section. Elastomeric material is used at the tray-to-grid attachments increases the damping of the system.
