  • the invention relates to a method for separating liquid from a gas and liquid mixture moving as a stream in a separating space, in which the mixture is deflected and the liquid is separated on the wall of the separating space, and a separator for Execution of the procedure.
  • Pressure lines for the forwarding of gases are known, from which, in the form of fine mist or liquid droplets, moving liquids must be separated in the gas stream, for which purpose separators are used which operate according to the impact or the cyclone principle.

Abstract

Le flux (E) de gaz et liquide entrant dans le separateur est anime d'un mouvement de rotation helicoidal par une roue directrice (35), en direction d'un manchon de sortie (22); le liquide entraine dans le courant est entraine contre la paroi interne (29) d'un tube interieur (27) et se deplace dans la direction du courant. A l'extremite du tube interieur (27), le liquide est detourne par une partie du courant (II) dans une fente (30), qui est formee entre le tube interieur (27) et le tube formant separateur (23). Le liquide accede, par la fente (30), a une chambre collectrice (34) et est ainsi detourne. La partie du courant (II) est detournee dans la chambre collectrice (34), liberee du liquide encore existant et ensuite dirigee, par un tube de liaison (32), en direction du manchon de sortie. Par la creation du flux separe (II), le liquide se separe obligatoirement, ce qui permet un volume de construction plus petit pour le separateur.
