<p>The invention relates to a device for separating liquids and/or solids from a high-pressure gas stream, comprising a cylindrical vessel with a virtually vertically set axis fitted with: a top compartment to which the gas stream is fed; a middle compartment comprising a number of blades set helicoidally around the axis; a bottom compartment for separating the gas and the liquid and/or solids and a coaxial gas discharge pipe projecting upward from the bottom compartment through the middle and the top compartments, around which helicoidal blades have been fixed, each helicoidal blade being composed of a bottom section with a constant pitch and a section with a pitch gradually increasing in upward direction. The constant pitch of the blades lies between 5 and 20 &loz& , preferably between 10 and 15 &loz& and increases in upward direction to at most 60 &loz& , preferably 45 &loz& . Between the helicoidal blades are vertical baffles which, viewed in the flow direction of the gas, extend from the discharge pipe in the direction of the inner wall of the vessel. These baffles are shaped like flat planes with sharp free ends. Conical sleeve sections are provided in the separation section of the device, at the outer wall of the gas discharge pipe, the angle between the sleeve sections and the centre line of the vessel being between 15 and 45 &loz& . The distance between the free end of the sleeve sections and the inner wall of the vessel is between 0.25 and 0.70 and by preference between 0.3 and 0.6 of the distance between the outer wall of the gas discharge pipe and the inner wall of the cylindrical vessel.</p> |
