Definitions
- the invention relates to a method in which one is under pressure standing pipe flow is given a spiral movement and then an axial pipe flow is obtained, the Inflow against a height-adjustable flow guide is directed.
- the invention also relates to a device with a deflection or branching of a pressurized pipe flow with a built-in part that is adjustable in height and one itself from the area of the tangential inlet to the axial outlet the swirl chamber tapering.
- the invention also relates to the application of Device of the method on the inflow of inlets for Round pools, sand classifiers, vortex separators, hydrocyclones or vortex cleaners, centrifugal separators, hydrocyclone separators as well as distribution structures for incoming water masses.
- Such methods and devices are used both in Water such as wastewater, or more specifically in the hydraulic engineering of the settlement industry as well as in laboratory and process engineering.
- Rotationally symmetrical spiral movements are in different Applications and methods of hydraulics advantageous.
- Such Tasks arise both in hydraulic engineering and in urban water management and in laboratory and process engineering.
- In the wastewater sector there is usually a uniform load of different Basin to aim for, whereas in the laboratory and Process engineering a stable spiral movement in pipe strings can be advantageous or even a desired effect, such as e.g. a separation process, can only trigger.
- the disadvantage so far Swirl chamber shapes used e.g. according to Adami, Drioli, Knapp, Thoma etc.
- the reason for this is the non-uniform pressure distribution the swirl chamber circumference and insufficient pressure redistribution given at the transition from the tangential to the axial tube. Thereby becomes the developing air or liquid Vortex core deflected to one side.
- DE-OS 36 30 536 can be as it is described and shown, do not work. In addition, there would be another asymmetrical part Treatment of the asymmetrical flow necessary. At a such device known from DE-OS 36 30 536 now set the considerations that led to the invention.
- the invention is based, by means of a simple task Construction with little effort a rotationally symmetrical or any eccentric spiral movement of a liquid only in the axial tube attached to a swirl chamber Pressure redistribution and flow diversion independent of the flow to evoke.
- this object is achieved according to the invention solved that to achieve an almost arbitrary across the cross section distributed spiral movement redirected the flow or is branched by the vertical from the tangential inflow for this outgoing outflow by directing the flow is caused and that the passage area for the swirl flow is tapered in the direction of the axial flow and in Area of swirl the flow around one with respect the eccentricity adjustable with respect to the swirl chamber axis, if necessary, trained as an installation part Flow guide and rectifier is performed.
- the tapers Swirl chamber conical which has the consequence that the initially large passage area of the swirl chamber in the axial direction up to Outflow opening continuously becomes smaller and thus pressure equalization over the flow cross section in the axial direction.
- this pressure redistribution can brought about by installing the cylinder or cone be the axis of symmetry of the cone or cylinder eccentric to the axis extended into the swirl chamber of the axial tube is arranged.
- the conical surface is preferably inclined more steeply than the swirl chamber boundary. At least, however, he must be inclined just as much to avoid enlarging the flow cross-section. Therefore, the cone tip or the cylinder should be used end below the transition to the axial tube to end up to the axial Provide outlet for pressure redistribution.
- the swirl chamber generally becomes one with the axial outlet opening Operate vertically up or down. Also one Swirl chamber inclined at any angle creates a rotationally symmetrical one Spiral movement in the liquid when leaving the Swirl chamber due to the compensation according to the invention.
- a ventilation opening or a second outlet opening can be placed in the center of the swirl chamber base.
- the conical or cylindrical installation is not enough to the swirl chamber base.
- the built-in part itself also ensure ventilation.
- the inlet cross section can be tapered into the swirl chamber flow, which means higher inflow speeds compared to one existing pipe cross-section can be achieved. This also increases the rotational speed in the swirl chamber and in the subsequent one Pipe.
- a continuous connection can also be used for certain applications be created between two outlet openings by the cone or cylinder is drilled through the center or in the center becomes.
- a conical one Installation part is designed as a double cone.
- the advantages achieved with the invention are in particular in that by continuously reducing the axial flowed cross section at the transition from the swirl chamber in the axial pipe of the liquid without mechanical fittings or other measures imprinted a rotationally symmetrical rotary movement becomes.
- the swirl chamber shape does the opposite to continuous swirl chamber shapes Transition from the swirl chamber base to the axial outlet results in and thus in connection with the adjustable built-in part a gradual one Pressure redistribution becomes possible.
- swirl chamber shapes With previously used and examined swirl chamber shapes to generate rotation in a medium the sudden transition from the Swirl chamber to the axial tube pressure potentials leading to an uneven Acting led across the flow cross section.
- a particular advantage of the invention can also be found in the field of water management for distribution structures for incoming Use water masses. Such distribution structures take that arriving water and distribute the amount of water among different Pelvis evenly.
- a swirl chamber with a reduction in the flow cross section is shown in section.
- the tangential swirl chamber inlet 1 opens into the swirl chamber base 2 indicated by dashed lines and is guided around an installation 3 at an altitude and eccentricity with respect to the swirl chamber axis.
- the installation 3 is a cylindrical installation element that sits snugly on the swirl chamber base 2. The end face of the cylinder 3 is always below the axial opening 6.
- the water Q flows tangentially into the swirl chamber 5, where it moves spirally in the flow cross section between the cylinder installation 3 and the conical swirl chamber wall 4 towards the axial outlet 6.
- the pressure is increasingly compensated for by the flow as the flow continues up to a certain area dependent on the pressure cross-section by rearrangement. The result of this is that a rotationally symmetrical or arbitrarily eccentric, spiral-shaped rotary movement is formed in the axial derivative 6.
- FIG 3 shows a swirl chamber in which the required pressure redistribution is established by the flow between the conical surfaces and the jacket of the swirl chamber.
- the cone is always inclined more steeply than the swirl chamber 4 surrounding it.
- the installation part 3 (here a cone) can be fixed in such a way that a certain distance clears the second opening 10.
- the rotationally symmetrical spiral movement of the flowing medium in the outlets occurs only when the cross-sectional reduction 5 is passed through, not when the opening 10 is made in the swirl chamber base 2.
- Fig. 4 shows an inflow partly from above, the outflow goes axially downwards.
- the installation part is a cone 11, which has a through bore 12. So there is a ventilation or venting via the bore 12.
- FIG. 5 shows a toroidal casing 7 of the swirl chamber, by means of which the pressure redistribution is brought about in accordance with the respective requirements by a suitable combination with a specific shape of an installation part 8 or a moderate taper.
- Fig. 8 shows the case where a rotationally symmetrical rotational movement of the liquid occurs in two axial tubes 6 and 6b.
- the outer surface of the swirl chamber wall 4 is designed accordingly and a double-symmetrical mounting part 13 is realized.
- FIG. 9 A representation similar to FIG. 2 shows FIG. 9 , only that the tangential inlet 9 is designed to narrow or taper. As a result, the flow rate can be increased to a level necessary for swirl formation.
- Fig. 1 i.e. the one with a smooth cylinder can be so developed that instead of the smooth top cylinder surface of the cylinder top hemispherical, parabolic, is rounded off conically, the embodiment can also 1 provided with an axially parallel bore be.
- the surface of the built-in element will always be smooth.
- the cone can also have a rounded cone head, a parabolic rounded cone head, a truncated cone or a have a rounded truncated cone.
