ABSTRACT:
An improved apparatus for cleaning particle-laden gas, of the type which includes a duct where liquid droplets are introduced into particle-laden gas flowing through the duct, a demister in the duct for removing liquid and particles from gas which moves through the duct. The improvement includes at least one curved flow path in the demister for causing the gas to change direction and a liquid collection surface defining the bottom of the demister. Collected liquid is removed from the liquid collection surface. A liquid collection barrier is located downstream from the curved flow path and defines the downstream end of the liquid collection surface, the barrier extending the width of the flow path. A boundary surface is spaced above the collection surface and below the uppermost portion of the barrier and extends at least the greater portion of the width of the duct through the curved flow path for forming upper and lower sections and separating removed liquid and flowing gas, the boundary surface including a plurality of openings for communicating the upper and lower portions so that liquid can gravitate to or move toward the lower portion and gas can flow through the upper portion with minimal re-entrainment of liquid.
