Opfindelsen vedrører en hvirvelseparator til separering af en blanding af flere komponenter ifølge indledningen til hoved-5 kravet.The invention relates to a vortex separator for separating a mixture of several components according to the preamble of the main claim.
Sådanne hvirvelseparatorer arbejder med en fri hvirvelstrømning på den måde, at partikler, som har en større masse, under rotationen koncentrerer sig i separeringshvirvlens ydre dele, 10 og partikler med en mindre masse koncentrerer sig i de dele af hvirvlen, som befinder sig i rotationscentrets område.Such vortex separators operate with a free vortex flow in that particles having a larger mass concentrate in the outer parts of the separating vortex during rotation, and particles with a smaller mass concentrate in those parts of the vortex which are in the region of the center of rotation. .
En sådan hvirvelseparator kendes fra GB-PS 894 417. Ved denne kendte indretning findes overstrømningsåbninger i form af en 15 snæver slids, som kun gør det muligt for det yderste materialelag at træde over fra det ene hvirvelkammer og ind i det andet. I praksis viser det sig dog, at separeringsvirkningsgraden for en sådan kendt separator på ingen måde er optimal. Det skyldes åbenbart, at kollisionerne mellem nabohvirvler ikke 20 sker på den måde, at de til hinanden stødende hvirvler sammenklemmes og komprimeres for at opnå en effektivere separering. Partiklerne med en større masse i periferien i det ene hvirvelkammer går over i det andet hvirvelkammer efter gennembryd-ning af den pneumatiske spærring ved slidsen, og partiklerne 25 kan kun strømme i en retning gennem denne slids, og endvidere kan en kollision kun ske mellem den i en retning gennem slidsen strømmende strømning og hvirvelstrømmen i kammeret. Denne kollision begrænser strømningen gennem slidsen, men komprimerer på den anden side ikke hvirvlen i det andet kammer.Such a vortex separator is known from GB-PS 894 417. In this known device there are overflow openings in the form of a 15 narrow slot which only allows the outermost material layer to pass from one vortex chamber into the other. In practice, however, it appears that the separation efficiency of such a known separator is by no means optimal. This is evidently due to the fact that the collisions between neighboring vertebrae do not occur in the way that the adjacent vertebrae are squeezed and compressed to achieve more efficient separation. The particles having a larger mass on the periphery of one vortex chamber pass into the other vortex chamber after the pneumatic blockage is pierced at the slot, and the particles 25 can flow only in one direction through this slot, and furthermore, a collision can only occur between it. in a direction through the slit flowing stream and the vortex flow in the chamber. This collision restricts the flow through the slit, but does not, on the other hand, compress the vortex of the second chamber.

Ved genstanden for GB-PS 1369 785 kan det fastslås, at der her kun findes en separeringshvirvel, medens det ved den anden hvirvel drejer sig om et aksialt væsentligt kortere kammer, som ikke har nogen separeringsfunktion og kun tjener til til-35 førsel af fortyndingsmiddel (vand) på et specielt langt nede liggende sted med en forholdsvis ringe aksial udstrækning i forhold til længden af det egentlige separeringskammer. Det drejer sig altså også ved dette modhold ligesom ved genstandenBy the object of GB-PS 1369 785 it can be stated that there is only one separating vortex here, while in the other vortex it is an axially substantially shorter chamber which has no separating function and serves only for the supply of diluent. (water) in a particularly low-lying location with a relatively small axial extent relative to the length of the actual separation chamber. That is also the case with this opposition, just as with the object

for FR-PS 1378 555 ikke om en separering, men om lige det modsatte, nemlig en formålstjenlig form for tilblanding henholdsvis sammenblanding.for FR-PS 1378 555 not about a separation, but about the exact opposite, namely an appropriate form of mixing or mixing.
5 Fra GB-PS 613 363 (fig. 7) kendes en hvirvelseparator, ved hvilken der omkring et cylindrisk centralkammer er anbragt flere ligeledes cylindriske kamre. Hvirvelstrømdelene nær væggene i de ydre kamre afskrælles ved dette apparat af de i centralkammeret indgribende vægdele af centralkammeret, som belt) grænser overstrømningsslidser, og ledes ind i centralkammeret.5 From GB-PS 613 363 (Fig. 7) there is known a vortex separator, in which several cylindrical chambers are arranged around a cylindrical central chamber. The eddy current portions near the walls of the outer chambers are peeled off by this apparatus by the wall portions of the central chamber engaging in the central chamber, which overlap slit slits, and are led into the central chamber.
Da overgangen ind i centralkammeret tvangsmæssigt sker allerede efter maximalt et omløb i de ydre kamre, kan separeringseffekten ikke være optimal ved denne form for komponentseparering, bortset fra de vedvarende stadige friktionstab ved alle 15 kamrenes omslutningsvægge.Since the transition into the central chamber is compulsorily already occurring after maximum circulation in the outer chambers, the separation effect may not be optimal in this type of component separation, except for the sustained steady friction losses at all 15 enclosure walls.
Til grund for opfindelsen ligger den opgave at forbedre en hvirvelseparator af den i indledningen nævnte slags således, at der lader sig opnå en væsentligt bedre separeringsvirk-20 ningsgrad med den.The object of the invention is to improve a vortex separator of the kind mentioned in the introduction so that a substantially better separation efficiency can be obtained with it.
Denne opgave er med en hvirvel separator af den i indledningen nævnte slags ifølge opfindelsen løst ved de i hovedkravene anførte kendetegn.This task is solved by means of a vortex separator of the kind mentioned in the introduction according to the invention by the characteristics stated in the main claims.

Fordelagtige videreudformninger fremgår af underkravene.Advantageous further designs are stated in the subclaims.
Denne udformning ifølge opfindelsen henholdsvis denne kombination af kendetegn udgør, så vidt det kan ses, den eneste vej, 30 der kan realiseres i praksis for at frembringe den ønskede optimale separering og bidrage på tredobbelt måde til forhøjelse af separeringsvirkningsgraden. For det første forkortes på grund af den betragtelige omkreds - længden af åbningen, der forbinder hvirvelkamrene med hinanden - længden af den stræk-35 ning, over hvilken hvirvlen i omkredsretning står i forbindelse med faste vægge. Da friktionen med hvirvlen i det pågældende nabokammer er væsentlig ringere end friktionen mod de faste vægge i det egne hvirvelkammer, afbremses hvirvelstrømningenThis embodiment of the invention or this combination of features, as far as can be seen, constitute, as far as can be seen, the only path which can be realized in practice to produce the desired optimal separation and contribute in triplicate to increase the separation efficiency. First, because of the considerable circumference - the length of the orifice connecting the vortex chambers to each other - the length of the distance over which the vortex in circumferential direction communicates with solid walls is shortened. Since the friction with the vortex in the neighboring chamber in question is substantially inferior to the friction against the fixed walls of the own vortex chamber, the vortex flow is slowed
3 DK 157784 B3 DK 157784 B
herved mindre kraftigt, så at, især når et givet hvirvelkammer står i forbindelse med flere nabohvirvelkamre på den beskrevne måde, friktionstabene forringes væsentligt, og dermed formindskes den til opretholdelse af en bestemt rotationshastig-5 hed nødvendige energi.hereby less vigorously so that, especially when a given vortex chamber is in contact with several neighboring vortex chambers in the manner described, the frictional losses are substantially degraded, thereby reducing the energy required to maintain a certain rotational speed.
For det andet opstår der, på grund af den delvis løben ind i hinanden af de til hinanden stødende hvirvler, knækpunkter i de uden for kollisionsfladerne cirkelformede strømningslinier.Second, due to the partial run into each other by the adjacent vertebrae, break points occur in the circular flow lines outside the collision surfaces.
10 Ved disse knækpunkter besidder strømningslinierne en væsentligt mindre krumningsradius end i de øvrige områder, så at der her optræder en forhøjet centrifugalvirkning. Med andre ord: de tunge partikler i blandingen tenderer i stærkere grad end de lettere partikler til at bibeholde deres bevægelsesretning 15 ved strømningsliniernes knækpunkter. Derved træder de tunge partikler i forstærket grad over i længere ude liggende og dermed hurtigere strømmende zoner af hvirvlen, hvorved de i forstærket grad skilles fra de lettere partikler.10 At these breaking points, the flow lines have a substantially smaller radius of curvature than in the other regions, so that there is an elevated centrifugal effect here. In other words, the heavy particles in the mixture tend more strongly than the lighter particles to maintain their direction of movement 15 at the breaking points of the flow lines. As a result, the heavy particles intensify to further out, and thus faster flowing zones of the vortex, thereby separating them from the lighter particles more intensively.
20 Endelig er det muligt ved passende gunstigt valg af kollisionsvinklen for de to ind i hinanden løbende hvirvler at holde strømningen i kollisionsfladeområdet laminar, mens friktionen mod de faste hvirvelkammervægge i umiddelbar nærhed af disse vægge fører til turbulensområder, som delvis igen ophæ-25 ver en separering mellem tunge og lette partikler, der allerede har fundet sted, og dermed alt i alt forringer separeringsvirkningsgraden .Finally, by conveniently selecting the angle of collision for the two successive vertebrae, it is possible to keep the flow in the collision surface region laminar, while friction against the fixed vortex chamber walls in the immediate vicinity of these walls leads to turbulence regions which partially cancel a turbulence. separation between heavy and light particles that have already occurred, and thus, overall, the separation efficiency deteriorates.
Ved samvirket mellem de tre omtalte fænomener, som kommer de-30 sto stærkere til udtryk jo flere dele af hvirvelkammervæggen der erstattes af nabohvirvler, lader der sig ved hjælp af ap-paratet ifølge opfindelsen opnå en væsentligt højere separeringsvirkningsgrad, end det hidtil har været muligt med kendte teknikker.By the interaction between the three mentioned phenomena, which is more strongly expressed the more parts of the vertebral chamber wall that are replaced by neighboring vertebrae, a significantly higher separation efficiency than has hitherto been possible is achieved. with known techniques.
Ganske vist viser det føromtalte FR-PS 13 78 555 en indretning med to til hinanden stødende cykloner, ved hvilke mod hinanden grænsende sidevægge er forsynet med åbninger, og hvirvelkamre- 35Admittedly, the aforementioned FR-PS 13 78 555 discloses a device with two adjacent cyclones, at which adjacent side walls are provided with openings, and vortex chambers 35

ne er således anbragt, at hvirvlerne løber delvis ind i hinanden under dannelse af en hvirvelkollisionsflade. Ved denne indretning drejer det sig dog ikke om en hvirvelseparator til separering af en blanding af flere komponenter med forskellig 5 partikelmasse i fraktioner af tunge og lette partikler, men om en indretning til udveksling af varme mellem gasformede, flydende og/eller finkornede faste medier og/eller til sammenblanding af sådanne medier. Der indføres altså her to gasformede eller flydende bæremedier, af hvilke hver bærer en slags 10 af de partikler, der skal blandes med hinanden, i hver et af de to hvirvelkamre, og fra hver af hvirvelkamrene træder par- .....- tikler over i nabohvirvelkammeret, så at der ved den nederste ende af hvirvelkamrene kan udtrækkes en godt sammenblandet partikelblanding, mens bæremediet strømmer ud foroven i det 15 væsentlige partikelfrit. Der sker altså her kun en separering af bæremedie og partikler, men ikke separering af en partikel-blanding i fraktioner med forskellig partikelmasse.are arranged so that the vertebrae run partially into each other to form a vertebral collision surface. However, in this device it is not a vortex separator for separating a mixture of several components of different particle mass into fractions of heavy and light particles, but a device for exchanging heat between gaseous, liquid and / or fine-grained solid media. / or for mixing such media. Thus, two gaseous or liquid carrier media are introduced here, each of which carries a kind of 10 of the particles to be mixed with each other in each of the two vortex chambers, and from each of the vortex chambers, particles of ..... into the adjacent vortex chamber so that at the lower end of the vortex chambers, a well-mixed particle mixture can be extracted while the carrier medium flows out substantially substantially particle-free. Thus, only separation of carrier media and particles occurs here, but not separation of a particle mixture in fractions with different particle mass.

Fig. 1 viser et hvirvelkammersystem, i hvilket de enkelte kamre er anbragt ved siden af hinanden i et firkantraster. Hvirvelsepareringskamrene 10 står i forbindelse med hinanden ved siderne, så at omtrent halvdelen af kamrenes vægflader bort-10 falder. I området for de bortfaldne vægflader dvs. åbningerne 12, danner sig kollisionsflader, i hvilke kamrenes hvirvler løber ind i hinanden. I det viste udførelseseksempel andrager antallet af hvirvler 4x4, men hele kammersystemet kan have et vilkårligt antal hvirvler 2, som parvis står i kontakt med 15 hinanden ved siderne. Ved eksemplet i fig. 1 befinder der sig mellem hvirvlerne 2 strømningsdelere 39, som i tværsnit på en vis måde er firearmede og som kan have forskellige størrelser. Også formen på strømningsdelerne 39 kan variere, som det fremgår af fig. 7-10 og 13.FIG. 1 shows a vortex chamber system in which the individual chambers are arranged side by side in a square grid. The vortex separating chambers 10 are interconnected so that about half of the wall surfaces of the chambers 10 fall away. In the area of the fallen wall surfaces ie. the openings 12, collision surfaces form in which the vertebrae of the chambers run into each other. In the illustrated embodiment, the number of vertebrae is 4x4, but the entire chamber system may have any number of vertebrae 2 which are in pairs in contact with each other at the sides. In the example of FIG. 1, there are between the vertebrae 2 flow dividers 39, which in a cross-section are in some way four-armed and which can have different sizes. Also, the shape of the flow portions 39 may vary as shown in FIG. 7-10 and 13.

Ved udførelsesformen i fig. 2 er hvirvlerne 2 udformet som en ellipse for at intensivere de radiale sammenstød. I eksemplet er ellipsernes hovedakser stillet retvinklet på hinanden. Alternativt kan ellipsernes hovedakser dog også forløbe paral-25 lelt med hinanden.In the embodiment of FIG. 2, the vertebrae 2 are designed as an ellipse to intensify the radial collisions. In the example, the main axes of the ellipses are positioned at right angles to each other. Alternatively, however, the main axes of the ellipses may also run parallel to each other.
Fig. 3 viser set fra siden et system ifølge fig. 4 med 4x4 hvirvelsepareringskamre 10, hvorved tilførselselementerne til kamrene ikke er vist. Tilførslen af et medie, der skal separe-30 res, kan ske aksialt eller tangentialt. I tilfældet i fig. 3 forlader de separerede fraktioner indretningen gennem aksiale afgange 13, 14, men tagentiale afgange er også muligt. Partikler med ringe masse går ud opad gennem afgangene 13, og partiklerne med tung masse nedad ud gennem afgangene 14.FIG. 3 is a side view of a system according to FIG. 4 with 4x4 vortex separation chambers 10, whereby the supply elements to the chambers are not shown. The supply of a medium to be separated can be axially or tangentially. In the case of FIG. 3, the separated fractions leave the device through axial departures 13, 14, but tagential departures are also possible. Low mass particles exit upwards through outlets 13, and heavy mass particles downward through outlets 14.
Udførelsesformen i fig. 4 tydeliggør, at de enkelte hvirvelsepareringskamre 10 har samme størrelse. Dette foretrækkes for at holde stød- henholdsvis sammenstødskræfterne i de forskel- 35The embodiment of FIG. 4 indicates that the individual vortex separation chambers 10 are of the same size. This is preferred in order to keep the impact and impact forces, respectively, in the differences 35

lige hvirvler ens. I dette tilfælde består strømningsdelerne 39 af fire glatte sektioner af cylindriske flader.even swirls alike. In this case, the flow portions 39 consist of four smooth sections of cylindrical surfaces.
Snitbillederne i fig. 5, 6 viser tangentiale åbninger 12, 5 hvorved disse er anbragt mellem de enkelte hvirvler 2.The sectional images in FIG. 5, 6 show tangential apertures 12, 5 whereby these are arranged between the individual vertebrae 2.
Fig. 7 viser en strømningsdeler 39, ved hjælp af hvilken hvirvlens strømningsretning frembringes, og netop med kanalag-tige noter, mellem hvilke der befinder sig skarpe ribber. Ved 10 en sådan formgivning er det muligt at modificere formen af en aksial sektion af hvirvlen 2 i rotationens forskellige højder. Inden for hvirvlens to kollisionsflader 40 er mellemfladen et plan. Når partiklerne kommer til strømningsdeleren 39 ifølge fig. 7, tvinges partiklerne til delvis også at bevæge sig i 15 aksial retning. Derved er de partikler, som har forskellig masse, snarere i stand til at komme forbi hinanden i den øns kede separeringsretning. Strømningsdelerens 39 tværsnitsform kan f.eks. også være en cirkel eller en ellipse. Således er strømningsdeleren 39 ifølge fig. 8-10 udformet bølgeformet i 20 aksial retning. Mellem bølgebjergene befinder der sig indsnit, ind i hvilke hvirvlen 2 tvinges. Den regelmæssige udformning af en hvirvel 2 i aksial og radial retning forbedrer separeringsvirkningen. Fig. 11 viser i detaljer den mulige anbringelse af en tangential åbning 12 til udførelsesformerne ifølge 25 fig. 5, 6.FIG. 7 shows a flow divider 39 by means of which the flow direction of the vortex is produced, and precisely with channel-bearing grooves between which are sharp ribs. In such a shaping, it is possible to modify the shape of an axial section of the vortex 2 at different heights of rotation. Within the two collision faces 40 of the vortex, the middle face is a plane. When the particles reach the flow divider 39 of FIG. 7, the particles are also forced to move in axial direction partly. Thereby, the particles having different masses are rather able to pass each other in the boring separation direction of the desired. The cross-sectional shape of the flow divider 39 may e.g. also be a circle or an ellipse. Thus, the flow divider 39 of FIG. 8-10 is formed in a 20 axis axial direction. There are incisions between the corrugated mountains into which the vortex 2 is forced. The regular design of a vortex 2 in the axial and radial direction enhances the separation effect. FIG. 11 shows in detail the possible application of a tangential aperture 12 to the embodiments of FIG. 5, 6.
Fig. 12 viser en udførelsesform med koniske hvirvelsepareringskamre 10 med strømningsdelere 39, som er vist forstørret i fig. 13. Størrelsen af kollisionsfladerne 40 kan vælges som 30 ønsket, hvorved strømningsdelerne 39 kan udvise flade, koniske flader eller de kan, som tidligere omtalt, være udformet bølgeformet eller været riflet i strømningsretningen eller notet i aksial retning.FIG. 12 shows an embodiment of tapered vortex separation chambers 10 with flow dividers 39 shown enlarged in FIG. 13. The size of the collision faces 40 may be selected as desired, whereby the flow portions 39 may exhibit flat, tapered surfaces or, as previously discussed, may be of corrugated shape or be grooved in the flow direction or grooved in the axial direction.

Centrifugalkraften i de små hvirvler 2’ er nedsat ved en tyndere rotationsmasse i forhold til centrifugalkraften i hovedhvirvlen 2, men på den anden si-5 de er de små hvirvlers 2’ centrifugalkraft forhøjet på grund af den lille radius i forhold til radius i hovedhvirvlen 2. Således er hvirvlen 2’ af forskellig størrelse i ligevægt med hensyn til centrifugalkræfterne. Ved dette udførelseseksempel er hovedhvirvlens 2 partikelmasse udsat for atten kollision-10 stød under et omløb. Kollisionsfladerne 40 forløber i den ydre del af hovedhvirvlen 2, strækker sig i tangential retning, og er således udformet henholdsvis dimensioneret, at de har den samme længde som deres afstandsafsnit. På grund af denne indretning henholdsvis dimensionering påtrykkes der på hoved-15 hvirvlen 2 regelmæssige bølgebevægelser. Strømningsdelerne er herved i praksis dannet af den skraveret viste apparatvæg.the small vortex 2 'is the same, however, the vortex velocity of the small vertebrae 2' is greater. The centrifugal force of the small vertebrae 2 'is reduced by a thinner rotational mass relative to the centrifugal force of the main vertebra 2, but on the other side the centrifugal force of the small vertebrae 2' is increased due to the small radius relative to the radius of the main vertebra 2. Thus, the vortex 2 'is of different size in equilibrium with respect to centrifugal forces. In this embodiment, the particle mass of the main vertebra is subjected to eighteen impact shocks during one orbit. The collision faces 40 extend in the outer part of the main vertebra 2, extend in a tangential direction, and are designed and sized, respectively, to have the same length as their spacing. Due to this arrangement and sizing, respectively, regular wave movements are applied to the main vortex 2. The flow parts are hereby formed in practice by the shaded device wall.
Fig. 15, 16 viser udførelsesformen i forbindelse med en centrifuge med rotationscentret 490. Rotationen i en centrifuge i 20 kombination med rotationen i hvirvlerne 2 forårsager en oscillationsbevægelse i hvirvlen, hvorved separeringen forstærkes. Oscillationen forhøjes derved, at de til hinanden stødende hvirvler kolliderer med hinanden. Vinklen mellem hvirvlernes 2 rotationscentre 49 og centrifugens rotationsakse kan variere 25 ifølge hvirvelsepareringskamrenes 10 konicitet eller cylindriskhed og længden af de ønskede kollisionsflader 40.FIG. 15, 16 illustrate the embodiment of a centrifuge with the rotation center 490. The rotation of a centrifuge in combination with the rotation of the vertebrae 2 causes an oscillatory movement in the vertebra, thereby enhancing the separation. The oscillation is increased in that the adjacent vertebrae collide with each other. The angle between the centers of rotation of the swirls 2 and the axis of rotation of the centrifuge can vary 25 according to the conicity or cylindricalness of the swirl separation chambers 10 and the length of the desired collision surfaces 40.
Fig. 17 viser den symmetriske anbringelse af rotationscentrene 49 for koniske hvirvler 2 i forhold til hinanden i aksialt 30 snit, hvorved væggene mellem enkelte hvirvler er fjernet fra de øvre områder 49 i et firkantraster målt langs en sfærisk flade 47.FIG. 17 shows the symmetrical arrangement of the rotation centers 49 of tapered vertebrae 2 relative to one another in axial section 30, whereby the walls between individual vertebrae are removed from the upper regions 49 in a square grid measured along a spherical surface 47.
Fig. 18 viser endelig en udførelses form, ved hvilken fire 35 hvirvler 2 frembringes mellem to små strømningsdelere 60 i stedet for en hovedstrømningsdeler. Derved bliver den friktionsflade, som definerer hvirvlerne 2, mindre. Mellem hvirvlen 2 og de med 60 betegnede små strømningsdelere fremkommerFIG. 18 finally shows an embodiment in which four swirls 2 are generated between two small flow dividers 60 instead of a main flow divider. Thereby, the frictional surface defining the vertebrae 2 becomes smaller. Between the vortex 2 and the 60 small flow dividers designated
