Abstract
Abstract A liquid eliminator comprising a plurality of blades for separating entrained liquid from a moving gaseous stream. Each blade has a sinuous, undulating configuration in the direction of the flow of gas with trapping vanes or traps as well as notched and serrated deflectors opening upstream intermediate the sinuous bends of the blades. The blades are mounted in parallel juxtaposition to form like, parallel sinuous paths between the blades for the passage of gas and removal of entrained liquid. The trapping vanes and serrated notches are preferably formed integrally with the blades. The trapping vanes are crescentshaped and join the blades at their downstream ends and are reentrantly curved with small upstream openings and a smoothly curved convex, bulbous mid-portions tending to form a venturilike passage with the opposite wall of the adjacent juxtaposed blade. The venturi effect accelerates the moving stream of gas and entrained liquid particles and projects the liquid particles out of the curving gaseous stream and into the next downstream trapping vane or trap. Sharp edged serrated liquid diverting means are also provided to trap or divert fine liquid droplets and mist downstream of the primary traps. An eliminator comprising the presently disclosed blades provides, compared with prior practice, a significantly greater volume throughout of gas with the liquid eliminated and with a significantly lower pressure drop from fluid inlet to gas outlet.
