Description
15 20 25 30 35 40 8008487- få Uppfinningen beskrivs närmare med hjälp av utföringsexempel i den följande ritningsbeskrivningen. I schematisk framställning visar fig. 1 tvärsnittet genom en avskiljningsanordning enligt uppfinningen (snitt A-A enligt fig. 2), fig. 2 snittet B-B enligt fig. 1, fig. 3 tvärsnittet genom en variant av uppfinningen (snitt D-D enligt fig. 4), fig. 4 snittet C-C enligt fig. 3, fig. 5 en variant av en avskiljningsanordning enligt fig. 4, fig. 6 detaljen Y enligt fig. 5, och §ig¿_1 en variant till figu- rerna 1 och 3. The invention is described in more detail by means of exemplary embodiments in the following drawing description. In schematic representation Fig. 1 shows the cross section through a separating device according to the invention (section AA according to Fig. 2), Fig. 2 the section BB according to Fig. 1, Fig. 3 the cross section through a variant of the invention (section DD according to Fig. 4), Fig. 4 shows the section CC according to Fig. 3, Fig. 5 a variant of a separating device according to Fig. 4, Fig. 6 the detail Y according to Fig. 5, and Fig. 1 a variant of Figs. 1 and 3.
Figurerna 1 och 2 visar en avskiljningsanordning huvudsakli- gen bestående av en virvelkammare 1, vilken bildas genom en krökt vägg Z och två_axiella begränsningsväggar 15. Utifrån skjuter tvâ sänkrör 8 spegelvänt och koaxiellt in i denna kammare. Dessutom mynnar en över kammarens hela bredd räckande inloppskanal 12 tan- gentiellt i kammaren. De axiella begränsningsväggarna uppvisar nära väggen 2 tömningsslitsar 14. Virvelkammaren är omgiven av ett uppsamlingshus 16, vilket med sitt nedre parti bildar en ficka 7.Figures 1 and 2 show a separating device mainly consisting of a vortex chamber 1, which is formed by a curved wall Z and two axial boundary walls 15. From the outside, two lowering tubes 8 project mirror-inverted and coaxially into this chamber. In addition, an inlet channel 12 extending over the entire width of the chamber opens tangentially into the chamber. The axial boundary walls have discharge slots 14 near the wall 2. The vortex chamber is surrounded by a collecting housing 16, which with its lower part forms a pocket 7.
Om nu genom kanalen 12 till exempel en med suspenderade partiklar försedd ström av en gas såsom en rågasström Qro leds in, så upp- står inuti virvelkammaren 1 en mycket snabbt roterande virvel.If, for example, a stream of a gas provided with suspended particles, such as a raw gas stream Qro, is now introduced through the channel 12, a very rapidly rotating vortex arises inside the vortex chamber 1.
Denna virvel antyds i fig. 1 genom pilarna 17. Till följd av vir- veln induceras inuti virvelkammaren 1 en sekundârströmning, vilken i fig. 2 visas genom pilarna 18. Genom de inuti virveln verkande centrífugalkrafterna förskjuts de i mediet medförda partiklarna mot väggen 2. Här grips de av sekundärströmningen 18 och transpor- Ateras i de axíella begränsningsväggarnas 15 riktning. I området av rotationskanterna mellan väggen 12 och de axiella begränsnings- väggarna 15 böjs strömningen 18 av med 900. Härvid förs partiklar- na ut ur virvelkammaren 1 genom slitsarna 14. De rör sig därvid i ungefär tangentens till strömningen 18 riktning genom tömnings- slitsarna 14. Efter att ha lämnat virvelkammaren faller partiklar- na ner i fickan 7. Den renade gasen lämnar virvelkammaren genom sänkrören 8 som rengasström Qrc. Det hur visat sig att även de finaste partiklar avskiljs, genom att de på sin väg, förorsakat av sekundärströmningen 18, kommer till sänkrörsmynningarna på sig vidgande skruvbanor i virveln 17 och därmed säkert kommer till väggen 2, så att de inte kan komma in i suget från sänkrörsmyn- ningarna. I sänkrörens omgivning befinner sig alltså en mycket verksam finavskiljníngszon.This vortex is indicated in Fig. 1 by the arrows 17. As a result of the vortex, a secondary flow is induced inside the vortex chamber 1, which in Fig. 2 is shown by the arrows 18. Due to the centrifugal forces acting inside the vortex, the particles entrained in the medium are displaced against the wall 2. Here they are gripped by the secondary flow 18 and transported in the direction of the axial boundary walls 15. In the region of the edges of rotation between the wall 12 and the axial boundary walls 15, the flow 18 is deflected by 900. In this case, the particles are carried out of the vortex chamber 1 through the slits 14. They then move in the direction of the flow 18 through the discharge slits 14. After leaving the vortex chamber, the particles fall into the pocket 7. The purified gas leaves the vortex chamber through the countersinks 8 as purge stream Qrc. It has been found that even the finest particles are separated, in that on their way, caused by the secondary flow 18, they reach the lowering pipe mouths on widening screw paths in the vortex 17 and thus safely reach the wall 2, so that they cannot enter the suction from the downcomers. In the vicinity of the lowering pipes there is thus a very effective fine separation zone.
Pig. 3 visar en virvelkammarc 1', som är anordnad innanför 10 15 20 25 800848714 b! en krökt vägg 2' och där till största delen omges av en rotations- kanal 3. Rotationskanalen 3 bildas genom en i tvärsnitt bågformig del 4, vilken radiellt sett är anordnad på ungefär konstant av- stånd från väggen 2 och sträcker sig över hela kammarbredden.Pig. 3 shows a vortex chamber 1 ', which is arranged inside 800848714 b! a curved wall 2 'and where it is for the most part surrounded by a rotation channel 3. The rotation channel 3 is formed by a cross-section arcuate part 4, which is arranged radially at an approximately constant distance from the wall 2 and extends over the entire chamber width.
Såsom framgår av fig. 4 har rotatíonskanalens axiella begräns- ningsväggar tömningsslitsar S, genom vilka vid virvelkammarens drift medíeandelar som skall avskiljas förs ut och kommer in i fickan 7. Liknande tömningsslitsar 14' kan även vara anordnade i virvelkammarens 1' axíella begränsningsväggar 15.As can be seen from Fig. 4, the axial boundary walls of the rotation channel have emptying slots S, through which during operation of the vortex chamber media parts to be separated are carried out and enter the pocket 7. Similar emptying slots 14 'can also be arranged in the axial boundary walls 15' of the vortex chamber 1 '.
Vid denna variant uppstår en strömningstekniskt mycket gynn- sam avskíljningsmekanism för dispergerade partiklar genom att i centrum Z, till exempel enligt fig. 4, enbart en delvolymström sugs ut. Härigenom uppstår längre uppehällstider för de exempelvis fina dammpartiklarna i virvelkammaren 1', så att dessa lättare kan föras utåt från finavskiljningszonen kring sänkröret 8. Ström- ningen i rotationskanalen 3 anrikas genom den fortlöpande rågas- tillförseln Qro till den grad med till exempel dammpartiklar, att gränsbelastníngen överskrids och partiklarna därför kontinuerligt och lätt förs ut genom tömningsslitsen 5. Härigenom förbättras den utsugna rengasandelen Qre avsevärt kvalitativt.In this variant, a very technically favorable separation mechanism for dispersed particles arises by sucking out only a partial volume stream in the center Z, for example according to Fig. 4. This results in longer residence times for the, for example, fine dust particles in the vortex chamber 1 ', so that these can be more easily carried outwards from the fine separation zone around the lower pipe 8. The flow in the rotation channel 3 is enriched by the continuous raw gas supply Qro to the extent that, for example, dust particles the limit load is exceeded and the particles are therefore continuously and easily carried out through the emptying slot 5. As a result, the extracted cleaning fraction Qre is considerably improved qualitatively.
Av fig. 5 framgår att tömningsslitsarna 5' och 14' är anord- nade i en speciell utformning. Denna utformning har den faktiska uträkningen, att partiklarna förs ut i ungefär tangentens till sekundärströmningen riktning. I rotationskanalen 3 uppstår sekun- därströmningen 9. Av fig. 6 framgår klart att genom det här för- skjutna anordnandet av begränsningsväggarna kan en ytterligare tömningsslits 6 anordnas. ' Fig. 7 visar tvärsnittet av en virvelkammare med en skalslits 10. Denna slits är så utformad att den liksom skär ut dammpartik- larna ur väggströmningen 11.Fig. 5 shows that the emptying slots 5 'and 14' are arranged in a special design. This design has the actual calculation that the particles are carried out in approximately the direction of the tangent to the secondary flow. The secondary flow 9 occurs in the rotation channel 3. It is clear from Fig. 6 that by arranging the boundary walls here offset, a further emptying slot 6 can be provided. Fig. 7 shows the cross section of a vortex chamber with a shell slot 10. This slot is designed so that it, as it were, cuts the dust particles out of the wall flow 11.
