ESP Collecting Plates
The "G" Opzel™ collecting plate incorporates Hamon Research-Cottrell's traditional Optimum Precipitation Zone ELectrode design, which provides quiescent zones to aide particulate collection and reduce re-entrainment. Plates are sheet steel roll-formed into panel plates that are shop welded together into assemblies.
The plate's structural integrity is fortified by the addition of rolled tube stiffeners at the top and bottom to make the plate more dynamically responsive to rapping. The mounting pad design is a hyperbolic transition section, which serves to gradually and efficiently introduce the rapping energy from the mounting pad into the collecting surface.
The "G" Opzel™ is constructed with a heavy gauge rolled top stiffener. The stiffener serves both to support the plate, and to provide a reliable connection to the top end plate. The "G" Opzel™ has only heavy gauge to heavy gauge welded plate at its support connection virtually eliminating failure/cracking that occurred in earlier designs and the designs of others. The "G" Opzel™ has both top and bottom stiffeners to provide straightness from leading to trailing edges. In addition, vertical straightness is provided by vertical stiffening baffles with overall section width of 4" (Note that these baffles provide electrical and gas flow quiescence functions as well). All panels of the plate are welded together to prevent manufacturing or operational twisting of panels off of the collecting plate centerline.
Another key element contributing to the successful operational record of the "G" Opzel™ collecting plate is the responsiveness of the plate to rapping. The "G" Opzel™ is constructed from panels which are attached eccentrically to each other, rather than having one continuous center sheet.
This eccentric assembly causes the transfer of rapping energy from one panel to another to be perpendicular to the collecting plate surface. The g-level accelerations normal to the collecting plate surface are greatly enhanced by this construction. Studies have shown that approximately one half as much rapping energy is required to obtain a specific acceleration level with the "G" Opzel™, than is required with the continuous sheet designs (Typically called the "E" Opzel design in the ESP industry). Thus the rapping intensities that the plates are subjected to in order to obtain adequate cleaning, is greatly reduced. This also contributes to a longer life. To maintain proper clearances, scalloped spacer bars are supplied at the leading and trailing edge of the collecting plates at the bottom and also in the middle of the plate at the top and bottom. Whether you are refurbishing your ESP to improve efficiency in the short-term or would like to increase its long-term performance, our "G" Opzel™ collector plates will prove to be the collector plate best suited to your system requirements.
