S-20 Horizontal with horizontal lower barrel and vertical configuration. Source Peerless. Cyclone inlet section. As the mist-laden gas enters the separator the entrained liquids and solid particles are subjected to centrifugal force. The gas enters the cyclone tube at two points designated A and sets up a swirling motion. Solid and liquid particles are thrown outwardly and drop from the tube at point B. The swirling gas reverses direction at the vortex C and rises through the exit portion of the tube designated D. See Fig. S-21. S-18 Separators FIG. S-21 Cyclone operation filter separator. See text for key to components. Source Peerless. FIG. S-22 Mist extractor section. Source Peerless. Mist extractor inlet section alternate for some applications . As the gas enters the vane unit it is divided into many vertical ribbons A . Each ribbon of gas is subjected to multiple changes of direction B as it follows its path through the vanes. This causes a semiturbulence and rolling of the gas against the walls of the vanes C . The entrained droplets are forced to contact the vane walls where they impinge and adhere to the vane surface D . This liquid then moves into the vane pockets E and out of the gas stream. It is then drained by gravity into the liquid reservoir. The collected liquid can then be disposed of as desired. See Fig. S-22. Final separation element. The final separation section consists of one or more cylindrical coalescing elements mounted vertically on support tubes. The gas and fine mists pass from the inside to the outside of the elements. In passing through the coalescing elements the entrained mist particles diffuse and impinge on the closely spaced surfaces of the element and are agglomerated into larger liquid droplets. The larger liquid droplets emerge on the outer surface of the coalescing element and run down the sides of the element to the liquid collection chamber. The gas free of liquid particle entrainment rises and passes .
