Definitions
- the invention concerns a separator device comprising a preferably hollow section having decreasing diameter from the preferably open top towards a closed bottom, or preferably attached to a straight cylindrical tube, which may be closed at the bottom and which is arranged concentrically inside a tapered section of a hydrocyclone, having preferably the same shape as the invention, for separating gas or vapour from a liquid, or alternatively two other fluids with differing densities, i.e. oil/water.
- the invention can either be attached to the hydrocyclone walls using fixed connections such as stay rods and the like, or the device can be allowed to rotate, either by means of a motor or by arranging turbine blades at the outlet of the invention's tube section.
- classifiers which have the objective to separate solid particles of different diameters, or different densities, from a continuous liquid- or gas fluid.
- Classifiers represent actually an integrated two stage cyclone separator.
- the second stage separation chamber, removing the small/light particles, might at first hand look similar to the invention described in this patent application, i.e. US patent 2,706,045, but it has a completely different function.
- the main object of the invention is to prevent gas from being entrained in the liquid phase in cases where it is desirable to separate gas and liquid.
- a secondary object of the device is the ability to impart the gas-free liquid phase a substantial centrifugal field in order to achieve liquid/liquid (e.g. oil/water), or liquid/particle separation.
- fig. 1 shows a side view of a conventional hydrocyclone containing a device which is according to the invention
- fig. 2 shows a top view example of how the upper tapered part of the device may be affixed to the hydrocyclone's outer wall
- fig. 3 illustrates an example how the lower part of the device's tube section may be affixed to the cyclone's tapered outlet section.
- fig. 4 shows as an example a "cup" formed shape of the device.
- fig. 5 illustrates a practical arrangement of the invention inside a hydrocyclone for gas/liquid separation when the cyclone liquid outlet is submerged beyond a free liquid surface, i.e. cyclone used as an inlet device inside gravity separators.
- fig. 6 illustrates another practical arrangement of the invention inside a hydrocyclone for gas/liquid- or liquid/liquid separation where the cyclone body diameter is reduced in two or more sections.
- the invention is used inside the last tapered section of the cyclone.
- a "tapered" section means a section decreasing from a large diameter towards a smaller diameter.
- the shape of the tapered section can be conically, as shown in Fig. 1, or any suitable shape, e.g. as illustrated in Fig. 4.
- the preferably conically shaped annulus in Fig. 1 (can also have other shapes such as shown in fig. 4) which is formed by the tapered cyclone inner wall 5 and the tapered section of the device 6 will create a back pressure in the flow and thus build up a pressure in the center of the separation chamber 1 allowing the lighter phase (i.e. the gas) to be forced through the vortex finder 4.
- This backpressure is developed according to the nature law of maintaing rotational momentum.
- the tangential component of the flow will increase substantially due to the decrease in cross-sectional diameter.
- the pressure from cross sections A-A to B-B will then decrease proportionally in order to maintain the total energy of the separated denser phase.
- Fig. 1 shows the highest reccomended axial location of the device 6 where the inlet of the device 6 is at the same axial height as the start of the cyclone's tapered section 5.
- the lowest reccomended location is determined by the cross- sectional inlet area of the formed annulus, which should preferably be larger than the cross-sectional area of the lower outlet pipe 10 of the cyclone.
- the tapered inlet section 6 of the device should have a diameter greater than 0.9X the diameter of the cyclone's lower outlet pipe 10, and smaller than 0.99X the diameter of the cylindrical section 1 of the cyclone.
- a conical section 6 is a preferred geometry of the device, it should be noted that it might have any shape when it is decreased from a large diameter to a smaller diameter.
- Fig. 5 shows a cup shaped geometry as an example.
- the preferred attached tube 7 shown in fig. 1 can be removed.
- Fig. 1 illustrates a hydrocyclone consisting of a cylindrical section 1, a tangential inlet 2, a circular top plate 3 with a through-going pipe 4 for extraction of the gas phase, a section 5 where the cyclone body diameter is decreased from a large diameter to a smaller diameter and preferably a discharge pipe 10 for extraction of the liquid phase.
- the invention comprises a device which is attached inside the cyclone's tapered section 5 consisting of a tapered section 6, having preferably a conical shape, which might be closed at the bottom or attached to a tube 7.
- the top of the tapered section 6 should preferably be open, but can be closed with a cylindrical plane plate as well.
- Fig. 1 illustrates how the invention is attached by stay rods 8 and 9 in a standard hydrocyclone.
- Fig. 2 illustrates how the invention's tapered section 6 is attached to the hydrocy clone's tapered section 5 with stay rods 8.
- Fig. 3 illustrates how the invention's tube section 7 is attached to the hydro- cyclone's outlet pipe 10 by stay rods 9.
- Fig. 4 shows as an example a "cup" formed shape of the device.
- Fig. 5 illustrates a practical arrangement of the invention inside a hydrocyclone for gas/liquid separation when the cyclone liquid outlet is submerged beyond a free liquid surface 1 1, i.e. the cyclone being used as an inlet device inside gravity separators.
- Fig. 6 illustrates another practical arrangement of the invention inside a hydrocyclone for gas/liquid- or liquid/liquid separation where the cyclone body diameter is reduced in two or more sections.
- the invention is used preferably inside the last tapered section of the cyclone.
