Abstract:
A cellular drift eliminator for removing mist from a mist-laden gas stream passing through the drift eliminator, the drift eliminator comprising:a plurality of blades having a longitudinally undulating shape wherein at least one undulation is oriented transverse to the direction of travel of the mist-laden gas steam passing through the drift eliminator, each of the blades having an upper edge and a lower edge, a front face and a rear face, the upper edges of the blades being located substantially in a first plane and the lower edges of the blades being located substantially in a second plane, the first and second planes being generally parallel to each other;a plurality of spacer elements wherein one spacer element is interspersed between every two blades, the spacer elements having a longitudinally undulating shape wherein at least one undulation is oriented transverse to the direction of travel of the mist-laden gas stream passing through the drift eliminator in an orientation corresponding to the orientation of the undulation of the blade, each of the spacer elements having an upper edge and a lower edge, a front face and a rear face and a plurality of corrugations oriented transverse to the spacer element undulation, each of the corrugations of the spacer element comprising two side walls connecting a flattened apex extending from the front face of the spacer elements and a flattened valley extending from the rear face of the spacer element, the lower edge of each spacer element having flat planar portions formed at the lower edge in the regions of the flattened apices and valleys of the corrugations and cut portions extending from the lower edge in the regions of the side walls of the corrugations;the spacer elements being attached to the blades such that at least some portions of the flattened apices of the corrugations of each spacer element are bonded to bonding portions of the rear face of a first adjacent blade and at least some portions of the flattened valleys of the corrugations of each spacer element are bonded to bonding portions of the front face of a second adjacent blade.
