  • Patent number: 4430101
    Abstract: The invention provides a separator blade for a mist eliminator of the kind comprising a plurality of parallel blades providing corresponding flow passages that change direction. A first direction change occurs immediately upon entry to the flow passage so that droplets are deposited on the blade front face. This part of the front face terminates in a primary collecting channel formed by a hook-like member protruding into the passage. The outer face of this hook-like member is convex curved and forms a venturi throat with the facing rear face of the adjacent blade. The blade is shaped to change the passage direction immediately after the throat and to provide an impingement surface at right angles to the gas flow that leads immediately into a secondary collecting channel formed by a respective hook-like member protruding into the passage from the rear face.

  • Patent number: 4292050
    Abstract: A separator for separating micron and submicron sized particles from a carrying gas, is disclosed. A carrier gas contains a component which is capable of condensation in the separator. The carrier gas is accelerated and flows at high velocity in a duct. The lower limit of the high velocity is approximately Mach 1.0. Due to the acceleration to the high velocity the static temperature of the carrying gas decreases. As a result, the condensable component condenses on micron and mainly on submicron sizes particles which act as nucleation sites. Liquid droplets formed during the condensation are in the micron size range. The paths of the high velocity flow of the carrier gas and of the solid and liquid particles carried therein is influenced by a combination of a centrifugal force and an oblique shock zone which is created within the high velocity flow. As a result, the particles travel a different path than the carrying gas and are effectively captured and disposed by an appropriately positioned receiving member.

  • Patent number: 4053292
    Abstract: A drop trap for a gas scrubbing plant, the trap having a plurality of parallel spaced apart corrugated plates forming channels through which gas flows and baffles at the downstream side of the corrugated plates to impart a downward velocity to liquid particles entrained in the gas flowing through the channels. Further baffles may be located at the upstream side of the corrugated plates to deflect the liquid particles downwardly to flow over the corrugated plates as they are separated from the gas as it passes through the channels. A method is also disclosed of rinsing the corrugated plates by intermittently spraying a predetermined quantity of liquid over the upstream side of the plates.

  • Patent number: 4017275
    Abstract: An improved type of centrifugal separator for separating liquids such as oil and/or water from a mixture of gas and liquid. It consists of an upright cylindrical shell divided by transverse dividers into three chambers. The mixture of gas and liquid is introduced through a tangential diverter into the lower chamber to produce a high velocity vortex of gas and liquid. A central axial vortex tube penetrates and is sealed through both transverse dividers. This vortex tube is comprised of two spaced longitudinally aligned portions which define a gap between them. The gap is positioned inside the central chamber. The upper end of the vortex tube extends into the top chamber and is sealed into a first mist extractor. The lower end of the vortex tube extends into the lower chamber.Due to the vortex action the liquid is thrown outwardly against the inner wall of the shell, the gas forming a high velocity vortex column along the central axis of the shell.
