    Guide device of a separation device
    The invention relates to a guide device of a separation device, in particular a centrifugal separator, for the separation of solid or liquid particles contained in a gaseous or liquid flow medium under the action of centrifugal forces, wherein the guide comprises at least one inlet opening and at least one outlet opening for the flow medium, wherein in the direction of flow of the Flow medium, the inlet opening and outlet opening along at least one flow path are arranged sequentially, and wherein the guide further comprises at least one curved baffle whose distance decreases from a longitudinal axis of the guide seen from the at least one inlet opening in the direction of flow of the flow medium.
    Furthermore, the invention relates to a separation device, in particular a centrifugal separator, for the separation of solid or liquid particles contained in a gaseous or liquid flow medium under the action of centrifugal forces, wherein the separation device comprises a guide device according to the invention and a dip tube.
    In general, centrifugal separators, which are also referred to as cyclone, cyclone separator, cyclone filter or whirler, serve as Massenkraftabscheider in technical systems for the separation of usually contained in gases solid or liquid particles, as is the case for example in the exhaust gas purification. To separate liquid mixtures so-called hydrocyclones are used.
    Both centrifugal separators and centrifuges use the centrifugal forces acting on the respective apparatus contents for separating substances. While in a centrifuge the necessary kinetic energy is transferred by the rotational movement of the container to the medium to be separated, gaseous or liquid flow media are used as a carrier medium of the deposited solid or liquid particles in the centrifugal separator, through their own flow rate and appropriate design of the separator, the flow media be put in a rotary motion. The substance separation takes place in the centrifuge by density differences of the different particles, in the centrifugal separator by the particle mass.
    Centrifugal separator or cyclone separator, for example, from the document WO 92/10300 Al for a long time already known. In particular, it is known from WO 92/10300 Al to use baffles in a guide device of a dip tube whose radii increase in the outflow direction of the medium, that is to say in the flow direction to the downstream dip tube. In this case, the fluidized flow medium in the guide undergoes not only a radial, but also an axial acceleration, whereby the subsequent transfer of the medium takes place in the subsequent dip tube aerodynamic and low energy loss.
    In WO 92/10300 Al, two different variants of guide devices are disclosed for this purpose. In a first embodiment, a front-side free end of a guide, which free end is flowed by the flow medium to be cleaned, open in the axial direction, in order to improve the flow behavior and to avoid pressure losses. A disadvantage of this design, however, is at least that the baffles are directly flowed in the frontal region of the guide from the medium to be cleaned and can swing freely without stabilization measures. Furthermore, in addition to dynamic loads acting on the baffles during operation, thermal deformations of the baffles due to temperature differences must also be taken into account. In particular, in a turbulent flow of the guide or a turbulent spiral flow within the guide the baffles are thereby set in vibrations, which can lead to excessive material loads up to the material tired of the guide. In addition, the flow behavior of the inflowing medium is adversely affected by the oscillating in the operating state baffles.
    In a second alternative embodiment, a closing plate or base plate is attached to the end of the guide shown in WO 92/10300 A1, which is intended to prevent flow medium from entering the guide device from the front side. Thus, the flow medium to be cleaned can only pass through lateral inlet slots in the interior of the guide. The inlet slots are bounded by adjacent edges of the adjacent baffles and by an edge portion of the subsequently arranged dip tube. A disadvantage of this design is at least that the end face arranged end plate obstructs an undisturbed influx of the guide and an influx of the inflowing medium into the guide in the form of a spiral flow.
    The variant of a guide device for centrifugal separator shown in document AT 413 339 B attempts to improve the second variant of a guide device with base plate known from WO 92/10300 A1 by providing recesses in the base plate in the region of the lateral inlet slots. Through these recesses in the
    Bottom plate, the cross-sectional areas of the lateral inlet slots are enlarged and these thus extend to portions of the frontal base plate. The appropriately cut base plate is similar in shape to a rotor, which has a rotor blade per baffle. A disadvantage of this design is at least that the production of the guide is complicated with a bottom plate with defined recesses. By the end face arranged bottom plate continues an undisturbed flow against the guide and an influx of the inflowing medium is hindered in the guide in the form of a spiral flow, although due to the recesses in the bottom plate of the flow resistance for the inflowing medium is reduced.
    In addition, during operation, in particular when depositing abrasive particles from a flow medium, there is the disadvantage that the cut-out bottom plate arranged on the end side of the guide element is exposed to material removal. Conversely, in the slipstream at the back of the cut bottom plate, thus thus on the side facing away from the inflowing flow medium side of the bottom plate, unwanted deposits of the medium form, which must be removed regularly at revisions.
    The present invention therefore has as its object to avoid the disadvantages known from the prior art for a guide device of a separation device of the type mentioned at the outset, as well as for a separation device comprising a guide device, and to provide a guide or a separation device , Which has a relation to the known prior art fluidically improved flow behavior of the medium to be cleaned with the lowest possible flow resistance. Furthermore, it is an object of the present invention to provide a guide or a separating device, which is particularly robust in dynamic loads and is flexible for different Abscheideaufgaben. Moreover, it is one of the objects of the invention to provide a guide device or a separating device, which can be manufactured in each case simply and cost-effectively with the least possible outlay on materials.
    These objects are achieved in a guide device according to the preamble of claim 1 having the features of the characterizing part of claim 1. The subclaims relate to further particularly advantageous embodiments of the invention.
    In a guide device according to the invention of a separating device, in particular a centrifugal separator, for the separation of solid or liquid particles contained in a gaseous or liquid flow medium under the action of
    Centrifugal forces, wherein the guide means comprises at least one inlet opening and at least one outlet opening for the flow medium, wherein the inlet opening and outlet opening are arranged along at least one flow path in the flow direction of the flow medium, and wherein the guide further comprises at least one curved baffle whose distance from a longitudinal axis the guide decreases from the at least one inlet opening in the direction of flow of the flow medium is at least one flow guide attached to the at least one baffle of a leading edge of the baffle in the flow direction by an axial distance attached, which flow guiding means projects into the at least one flow path.
    It is essentially assumed that the first embodiment shown in WO 92/10300 Al a guide without bottom plate, in which the guide is frontally open in the axial direction, so as to improve the flow behavior and to avoid pressure losses due to plate installations transverse to the axial direction. According to the invention, at least one flow-guiding means is now fixed on the at least one baffle, which projects into the at least one flow path from the front-side leading edge of the baffle in the direction of flow by an axial distance in the direction of the flow path of the medium to be cleaned. With the at least one flow guide, which projects into the flow path of the inflowing medium within the guide, the turbulent inflow behavior of the medium to be cleaned is stabilized, in particular in the inlet region of the guide, the helix angle of the inflowing medium becomes steeper and the flow profile of the turbulent flow within the guide uniform. Along with this, advantageously, the friction of the flowing medium on the inner walls of the guide can be further reduced. In addition, thus also the separation efficiency of the separation device can be increased and the selectivity for the separation of particles from the flowing medium can be improved. Thus, the incorporation of one or more Strömungsleitmittel in the guide this fluidically improved.
    By attaching the Strömungsleitmittels to at least one baffle, the corresponding baffle is also stabilized or stiffened. As a result, the inflow behavior of the inflowing medium into the guide device can also be improved indirectly, since due to the stiffening undesired vibrations of the guide plate are prevented or at least reduced. The free end face without bottom plate and the at least one inlet opening of the guide, which inlet opening is arranged on the guide, for example, as a side inlet slot, allow a
    Inflowing of the medium to be cleaned in the guide with flow components of the medium both in the axial direction, as well as in the radial direction, wherein advantageously the pressure loss along the flow path of the medium to be cleaned is reduced as possible.
    Furthermore, it is advantageous that the at least one flow-guiding means is set back by an axial distance from the leading edge of the baffle or in the middle of several baffles of the leading edges into the interior of the guide. Thus, the at least one flow guide is also mechanically protected against damage from the outside. For example, a guide device according to the invention can be turned off during assembly or maintenance work on the front-side leading edges of the baffles without being burdened or damaged by the leading edges spaced flow guide.
    Depending on the design or depending on the individual Abscheideaufgaben guide devices according to the invention may have an even or odd number of baffles. Likewise, the flow guide may vary in their total number or number of each attached to a baffle Strömungsleitmitteln. Likewise, within the scope of the invention, a plurality of differently shaped flow directors may also be used in one and the same guide device, which may differ from each other, for example, in their length, width, thickness, profiling and / or in their angle of attack with respect to the longitudinal axis direction of the guide device.
    In a guide device according to the invention, the at least one baffle can be curved in a particularly advantageous manner, preferably with a partial frustum, its axis of curvature preferably parallel to the longitudinal axis of the guide and the axis of curvature offset by a distance from the longitudinal axis and the radius of curvature of the at least one guide plate from the leading edge enlarged in the longitudinal axis direction of the guide. In this practical embodiment of the invention, the at least one baffle is unwound and thus relatively easy to manufacture.
    Suitably, in a guide device according to the invention, at least one flow-guiding means may be fastened to the guide plate in the radial direction with respect to the longitudinal axis of the guide device. In this embodiment, one or more flow directing means are each secured normal to the longitudinal axis direction of the guide. Thus, when using a plurality of flow guiding means, they may be arranged, for example, in one or more planes that are normal to the longitudinal axis direction.
    In a further preferred embodiment of the invention, in the case of a guide, the at least one flow guide can be set at an angle of attack with respect to the longitudinal axis direction, the angle of attack being from 5 ° to 60 °, preferably from 10 ° to 50 °. , Within the scope of the invention, it is also possible to arrange flow-guiding means with different angles of attack, in each case in relation to the longitudinal-axis direction. For example, first Strömungsleitmittel may be arranged in a first plane or at a first height level within the guide at a first distance from the free edge of the baffle with a larger angle of attack, for example, with 50 °, as is the case of second Strömungsleitmitteln the Lall, for example, with are provided at a smaller angle of attack of 30 ° at a greater second distance away from the free edge of the baffle away. Advantageously, the swirl of the flow is reduced by Strömungsleitmittel whose angle of attack is smaller, the closer they are attached in the direction of flow of the medium to the dip tube and the flow profile evened towards the dip tube out.
    Advantageously, the turbulent spiral flow can be deflected, evened out and / or stabilized within the guide device with one or more flow guiding means, which are arranged at a certain angle of attack to the longitudinal axis direction. By a corresponding selection of the angle of attack of the one or more flow-guiding means, the helix angle of the inflowing medium can be set steeper or increased, thereby reducing the friction of the flowing medium on the inner walls of the guide. Although it is one of the objects of the invention to provide a particularly robust guide in which the Strömungsleitmittel are fixed with fixed, rigid angles of attack or protrude into the respective flow path of the medium to be separated, so the invention is not limited to these embodiments , Likewise, it is possible within the scope of the invention, for example, to use flow guides whose angle of attack is mechanically and / or electrically adjustable.
    Advantageously, in a guide device according to the invention, at least two baffles may be provided, the axes of curvature of which run parallel to one another and to the longitudinal axis of the guide device. With such a symmetrical arrangement - the axes of curvature of the baffles running parallel to the longitudinal axis of the guide - can be advantageously arranged numerous baffles in a corresponding division. For example, so three, four or six baffles, which are each made with the same contour or curvature, rotor-like or propeller-like arrangement to a guide. Between the baffles are each, for example, spiral-shaped
    Flow paths for the flow medium, starting with the inlet openings or entrance gaps, in which the inflowing medium enters the interior of the guide.
    Particularly expediently, in the case of a guide device according to the invention, at least one flow guide can be fastened between adjacent guide plates. An advantage of this embodiment is that the flow guide are attached to adjacent baffles and stiffen these interconnected baffles thus particularly effective or stabilize. The Strömungsleitmittel thus act in addition to their flow conditions improving function as it were as reinforcing struts. Thus, unwanted vibrations of the baffles can be prevented as possible. Particularly economically, in this variant, the guide can be constructively designed so that the baffles or any other housing parts of the guide can be used with lower material thicknesses.
    In a further preferred embodiment variant of the invention, at least one flow-guiding means may be fastened to each guide plate in the case of a guide device. For example, in the case of a guide device with three baffles, which are arranged so as to be rotationally symmetrical about the longitudinal axis of the guide device by a pitch angle of 120 ° to one another, a total of three, six or nine flow guide means can be provided. For this purpose, the plurality of flow-guiding means can, for example, likewise be arranged in rotationally symmetrical or star-shaped fashion. The plurality of baffles may optionally be arranged left-handed or right-handed in the context of the invention.
    In a further development of the invention, at least one flow guide can be attached to at least one baffle in a guide device, wherein the at least two flow guide are offset from the leading edge of the baffle in the direction of flow by an axial distance, preferably by the same axial distance.
    In a further advantageous embodiment variant of the invention, at least one flow guide means spaced apart from one another in the longitudinal axis direction may be fastened to at least one guide plate in a guide device. In this embodiment, for example, flow guiding means between the guide plates can each be arranged in a plurality of planes spaced apart in the axial direction.
    Appropriately, in a guide device according to the invention, which further comprises at least one flow guide, the at least one flow guide in
    Direction of flow to be arranged downstream of the at least one flow guide, wherein the at least one Strömungsleitschaufel is at least partially attached to a guide plate and projects into a flow path.
    In this development of the invention, the guide additionally comprises one or more flow guide vanes, which are fastened to one or more baffles and further enhance the flow-directing or flow-conducting effect of the flow guide along the flow path of the medium. Such a flow guide vane can be helically bent or coiled, for example, comparable to a screw thread, and be attached in sections in its longitudinal direction or along a continuous guide blade edge to a guide plate. In addition to the positive flow influence - the turbulent flow in the interior of the guide is further stabilized by the Strömungsleitschaufeln and evened - is also the baffle to which the Strömungsleitschaufel is attached, further stiffened.
    It may be advantageous in a guide device according to the invention if the at least one flow guide vane is connected to at least one flow guide. In this embodiment, a flow guide and the downstream in the direction of flow of the flow guide vane are interconnected. Thus, the flow path of the flow medium within the guide can be influenced particularly effective streamlined.
    The aforementioned object of the invention is achieved in a separation device according to the preamble of claim 12 having the features of the characterizing part of claim 12.
    In a deposition device according to the invention, in particular a centrifugal separator, for the separation of solid or liquid particles contained in a gaseous or liquid flow medium under the action of centrifugal forces, wherein the separation device comprises a guide device according to the invention and a dip tube, the dip tube along the at least one flow path of the Conductor downstream in the axial direction and connected in the region of the outlet opening of the guide with this, wherein a longitudinal axis of the dip tube is preferably parallel, particularly preferably coaxial, to the longitudinal axis of the guide.
    The upstream of the dip tube in the flow direction of the medium guide serves to give the medium a radial and axial acceleration in the outflow direction of the medium to the dip tube out. Due to this acceleration in the outflow direction, the transfer of the medium from a separation chamber of the separation device into the dip tube takes place in a streamlined manner and with low energy loss.
    Advantageously, in a separation device according to the invention, a dip tube radius of the dip tube may be larger than the smallest radius of curvature of the baffle and / or smaller than the largest radius of curvature of the baffle. As a result of the radius of curvature of the baffle increasing in the direction of flow toward the dip tube, a spiral flow is impressed on the flow medium and the acceleration of the medium as it enters the dip tube is intensified.
    In a preferred embodiment of a separation device according to the invention, which further comprises at least one flow calming means, the at least one flow calming agent may be downstream of the at least one flow guiding means, wherein the at least one flow calming means at least partially attached to a baffle or to a plurality of baffles and / or within the dip tube is as well as in a flow path protrudes.
    In this embodiment, one or more flow calming means are provided, which may be fastened in the region of the guide device to one or more guide plates and / or are fastened to the inner wall of the dip tube. The flow calming agents advantageously protrude into the dip tube and thus serve as extensions of the guide plates into the dip tube. Thus, with the flow calming means, the swirl of the flow within the dip tube can be further reduced or evened out. With the help of the flow calming agent, the flow in the dip tube is further linearized and thus advantageously further reduces the pressure loss in the separation device, whereby a particularly economical operation of the separation device is possible. Unintentional turbulent back mixing and vortex formation, which can protrude into the dip tube and reduce the separation efficiency of the separator, are as possible prevented with the flow calming agents.
    A separating device according to the invention is particularly expedient if at least one flow calming agent is connected to at least one flow guide and / or at least one flow guide.
    In this embodiment, for example, one or more
    Flow calming means with at least one flow guide and / or be connected to at least one Strömungsleitschaufel, whereby the flow of the medium along one or more flow paths through the guide through and directed into the dip tube is streamlined and directed. Unwanted backmixing, which worsen the separation efficiency of the separation device or increase the energy loss during operation of the device, can be particularly effectively avoided in this embodiment. Thus, with such a separation device according to the invention even difficult deposition tasks can be done with low energy loss and high degree of separation.
    Further details, features and advantages of the invention will become apparent from the following explanation of exemplary embodiments schematically illustrated in the drawings. In the drawings: FIG. 1 shows a side view of a first embodiment of a device according to the invention

    FIGS. 1 to 3 each relate to a first embodiment of a separating device 1 according to the invention with a guide device 10. The following description relates equally to the views shown in FIGS. 1 to 3.
    In Fig. 1, the separation device 1 according to the invention with a guide 10 together with a subsequent dip tube 20 is shown. For a better overview, only the guide device 10 without dip tube 20 is shown in both FIGS. 2 and 3.
    The separation device 1 has a guide device 10, which in this case has a substantially frusto-conical shape and comprises a longitudinal axis 11 of the guide device 10. The guide 10 here has a plurality of lateral inlet openings 15 and inlet gaps 15, the gap widths 16 have. These gap widths 16 of the inlet openings 15 here in the conical part of the guide 10 are dependent on the respective position or position in the longitudinal axis direction 11 and therefore can not be regarded as constant. The gap widths 16 are thus variable here in the longitudinal axis direction 11, but can also be designed with a constant gap width in the context of the invention in an embodiment not shown in the figures.
    The dip tube 20 has a longitudinal axis 21 of the dip tube 20 and a radius T and closes in the region of an outlet opening 25 flush to the upstream in the flow direction of the medium to be cleaned guide 10. The dip tube 20 is thus arranged downstream in the outflow direction of the medium of the guide 10. In FIGS. 1 to 4, the longitudinal axis 11 of the guide 10 and the longitudinal axis 21 of the dip tube 20 are each arranged coaxially or collinearly. In the first embodiment of the invention shown here, three baffles 30 are arranged spirally or helically rotated relative to each other. The baffles 30 are here rotationally symmetrical about the longitudinal axis 11 of the guide 10 each offset by a pitch angle of 120 ° to each other and are coiled left-handed here. Likewise, the plurality of baffles 30 may be arranged in the context of the invention also clockwise. The baffles 30 are here partially conical or partially frustum-shaped curved, wherein the axes of curvature 31 extend parallel to the longitudinal axis 11 of the guide 10 here. Each axis of curvature 31 is offset by a distance a from the longitudinal axis 11 of the guide 10. The radius of curvature r, R of the baffles 30 thereby increases from an in the mounting position usually underlying leading edge 35 in the longitudinal axis 11 with increasing altitude of the guide 10. The smallest radius of curvature r of a baffle 30 is here at the lowest at a height Ho of the free leading edge 35 of the baffle 30th measured. The largest radius of curvature R of the baffles 30 occurs at the transition of the frusto-conical in the cylindrical portion of the guide 10. The baffles 30 form the outer contour of the frusto-conical region of the guide 10 and are open in the axial direction downwards.
    In the embodiment illustrated in FIGS. 1 to 3, two flow-guiding means 40 are respectively fastened between adjacent guide plates 30. The flow guide 40 are each offset by an axial distance h from the free edge 35 and the free leading edge 35 of the baffle 30 in the axial direction 11 into the interior of the guide 10 offset. Advantageously, the flow guide 40 are thus not damaged when the guide 10 must be removed and turned off, for example, for assembly or maintenance purposes. The flow guiding means 40 have a height 41 in the axial direction 11 and a width 42 in the radial direction. In relation to the height level of the guide 10 in usually vertical operating position are thus at a height level Ho, the free leading edges 35 of the baffles 30, at a height level Hi the lower edges of the flow guide 40 and at a height level H2, the upper edges of the flow guide 40. In the here a total of six flow guide means 40 are provided, all of which are arranged at the same height level Hi or H2 and are fastened essentially in the radial direction or perpendicular to the longitudinal axis 11 between adjacent guide plates 30.
    The flow guiding means 40 are here profiled by way of example in cross-section with a wing profile and are set at an angle of attack α with respect to the longitudinal axis direction 11. The angle of attack α is here about 40 °.
    In further embodiments of the invention, not shown, three, nine or twelve flow-guiding means 40 can be provided, for example, in the case of three guide plates 30. For this purpose, the plurality of flow-guiding means 40 can also be arranged, for example, in rotationally symmetrical or star-shaped fashion. Furthermore, in the context of the invention, the flow-guiding means 40 can be arranged at the same height level with respect to the longitudinal axis of the guide 10 or at different height levels.
    In Fig. 4 is an isometric view obliquely from below a second embodiment of the invention with a separator 1 with the guide 10 together with the adjoining dip tube 20 illustrated. In FIG. 4, similar to the images shown in FIGS. 1 to 3, six flow-guiding means 40 are also fastened in the radial direction or perpendicular to the longitudinal axis 11 between adjacent guide plates 30. These first flow guide 40 are each offset by an axial distance h from the free edge 35 and the free leading edge 35 of the baffle 30 in the axial direction 11 into the interior of the guide 10 offset. The angles of incidence α of the first flow-guiding means 40 with respect to the longitudinal-axis direction 11 are here by way of example about 60 °. In the axial direction 11 spaced therefrom or offset toward the dip tube in the direction of the flowing medium 100, further, second flow guide means 40 are arranged here, which second flow guide means 40 have a smaller angle of attack α, for example of approximately 30 °. The angle of attack α of the second flow-guiding means 40 is again determined in relation to the longitudinal axis direction 11. Advantageously, the swirl of the flow is further reduced by the flow direction of the medium 100 towards the dip tube 20 with decreasing angles of attack α arranged flow guide 40 and the flow profile evened towards the dip tube out.
    In order to illustrate the flow, arrows 100 are shown in FIGS. 1 to 3 for the first and in FIG. 4 for the second embodiment and also in the figures described below, which are intended to symbolize the flowing medium 100 to be purified. The medium 100 is for this purpose transported in a direction of flow 110 to the inlet openings 15 and to the longitudinal axis 11 in the free leading edges 35 of the baffles 30. The direction of flow 110 of the medium 100 can be broken down component by component into an axial flow component 111 of the medium 100 as well as into a radial flow component 112 of the medium. In the following, the term "axially" refers in each case to the longitudinal axis direction 11 of the guide 10 or to the longitudinal axis direction 21 of the dip tube and the term "radially" to the spatial directions perpendicular to the longitudinal axis directions 11, 21. The inflow direction 110 and its components 111, 112 are likewise symbolized in each case as arrows.
    The flowing medium 100 is guided within the guide 10 along one or more flow paths 120 through the guide into the subsequent dip tube 20. The flow guiding means 40, which project into the flow path 120 of the inflowing medium 100 within the guide device 10, serve to stabilize the turbulent inflow behavior of the medium 100 to be cleaned, in particular in the inlet region of the guide device 10. Furthermore, the flow guide means 40 advantageously serve to even out the swirl of the flow of the medium 100, thereby reducing the friction losses of the flowing medium 100 on the inner walls in the separation device 1, thus the guide 10 and the subsequent dip tube 20.
    FIG. 5 shows a third embodiment of a separation device 1 according to the invention with a guide device 10 and subsequent dip tube 20, wherein both flow guide means 40 and flow guide vanes 50 are provided in the guide device 10. FIG. 6 shows, in a plan view from above, the separating device 1 according to the invention shown in FIG. 5. The following description relates equally to the two illustrations FIG. 5 and FIG. 6.
    The three flow guide vanes 50 shown here-in each case one flow guide vane 50 per baffle 30 -are in each case arranged downstream of the flow-guiding means 40 in the direction of flow 110 of the medium 100 and are each connected to a flow-conducting means 40. In addition, the flow guide vanes 50 are each attached in sections to a guide plate 30 and project into the flow path 120 of the medium 100. The flow guide vanes 50 have in the axial direction 11 a height 51 and in the radial direction respectively - depending on the respective height level in the longitudinal axis direction 11 - variable widths 52 on. In FIG. 5, the fluidizing paddles 50 each extend to a height level H4 of the upper edge of the flow guide vane 50.
    Alternatively, some or all of the flow vanes 50 could reach to a different height level H3 of the top edge of the flow vanes 50. Advantageously, due to their helical arrangement, the flow guide vanes 50 not only serve to even out the turbulent swirl flow inside the guide 10 or to linearize the flow profile, but the flow guide vanes 50 also increase the rigidity and stability of the guide vanes 30.
    FIG. 7 shows a fourth embodiment of a separation device 1 according to the invention with a guide device 10 and subsequent dip tube 20, wherein flow guide means 40 are provided in the guide device 10 and flow calming means 60 are additionally provided within the dip tube. FIG. 8 illustrates in a plan view from above the separating device 1 according to the invention shown in FIG. 7. The following description relates equally to the two illustrations FIG. 7 and FIG. 8.
    In addition to the flow guiding means 40, a plurality of flow calming means 60 are provided here which project into the interior of the immersion tube 20 with an axial height 61 of the flow calming means 60 and a width 62 of the flow calming means 60 up to a height level H5 of the upper edge of the flow calming means 60. The flow calming means 60 serve to further linearize the flow of the medium 100 to be purified in the dip tube 20, thus to further uniform the flow profile of the medium 100 within the dip tube 20 in order to be able to further reduce undesirable pressure losses. Furthermore, the separation performance of the separation device 1 is further increased by an advantageously uniformed flow in the dip tube 20, thus further improving the selectivity for particles to be separated from the flow medium 100.
    The three flow calming means 60 shown here are arranged downstream of the flow guiding means 40 in the flow direction 110 of the medium, the flow calming means 60 being fixed at least in sections inside the dip tube 20 and projecting into the flow path 120 of the medium.
    As also provided in the context of the invention, but not explicitly illustrated in the drawings, the flow calming means 60 can also be attached to one or more baffles 30 and also already protrude into the flow path 120 of the medium 100 in the baffle 10. Likewise, one or more flow calming means 60 may be connected to at least one flow guiding means 40 and / or to at least one flow guiding vane 50. In this embodiment, the respective flow guiding means 40 and / or flow vanes 50 with the flow calming means 60 respectively form units which are recessed within the guide 10 from an axial distance h, which is set back from the free leading edges 35 of the baffles 30 inward or in the axial direction 11 , extend into the dip tube 20 in and determine the flow path 120 of the medium 100 so significantly.
