Patent CA-2184776-A1 (CA)
Inventor: HSIEH CHANG-LI
IPC: B01D47/06
Filed: 1996-09-04
Abstract: The invention relates to a mist eliminator wash system, typically with chevron-type blades, employed with a horizontally flowing gas stream, and to an improved method of washing the mist eliminator, and to a mist eliminator system employing the mist eliminator and washing method.  A bladed, chevron-type mist eliminator apparatus removes or reduces said entrained liquid and particles from the gas stream; wash streams upstream of the blades providing wash water to remove solids from the upstream portions of the chevron blade surfaces, the wash water initially flowing co-current with the horizontal flow path of the gas stream; and wash streams downstream of the blades directing wash water countercurrent to the gas stream flow, to remove solids from the downstream portions of the chevron blades.  The method of the invention includes directing a plurality of concentrated wash streams from concentrated wash nozzles to provide flat wash streams against the downstream end of the mist eliminator, the streams in a non-overlapping arrangement, to remove solids from the downstream portions of the chevron blades, and reducing the entrainment of such wash liquid in the clean gas.  The flat stream nozzles may be arranged to move vertically and also to arcuately rotate to cover selected areas of the downstream blade surfaces, which action of the stream nozzles may be used alone, in combination, or sequentially as desired.
