DK 152972BDK 152972B

Opfindelsen angår en cyklonudskiller til fjernelse af partikler fra et gasformet bærermedium med et rotationssymmetrisk hus med lodret rotationsakse, i hvis øvre område en tilnærmelsesvis horisontal indløbsstuds føres i tangential retning i forhold til husets væg, med et 5 gasudløb i den Øvre ende af huset og en under gasudløbet anbragt vandret plade, som holder et langs rotationsaksen forløbende, cylindrisk rør, som fører op gennem pladen.The invention relates to a cyclone separator for removing particles from a gaseous carrier medium with a rotationally symmetrical housing with a vertical axis of rotation, in the upper region of which a substantially horizontal inlet nozzle is guided tangentially to the wall of the housing, with a gas outlet at the upper end of the housing and a located below the gas outlet is a horizontal plate which holds a cylindrical tube extending along the axis of rotation leading up through the plate.

En fra AT-patentskrift 2 89 729 kendt cyklonudskiller af den ovennævnte art samler partiklerne, som kan være faste eller flydende, i 10 et nedad aflukket, såkaldt hvirvelkammer. Til dette formål skal den i nærheden af gasudløbet, direkte neden under den tangentiale røggastilførsel anbragte plade forhindre medrivning af udskilte partikler af den rene gas, fordi den stabiliserer strømningen i hvirvelkammeret, dvs. gasrotationen også neden under pladen. Et sådant lukket, 15 hvirvelkammer, som altså danner en bunker, er imidlertid kun egnet til små mængder af partikler, således som de forventes ved den støvudskillelse, som er anført som anvendelsesområde for det kendte hvirvelkammer.A cyclone separator of the aforementioned kind known from AT Patent 2 89 729 collects the particles, which may be solid or liquid, in a downwardly closed, so-called vortex chamber. For this purpose, the plate placed near the gas outlet directly below the tangential flue gas supply must prevent entrainment of separated particles of the clean gas because it stabilizes the flow in the vortex chamber, ie. the gas rotation also below the plate. However, such a closed, vortex chamber, thus forming a bunker, is suitable only for small amounts of particles, as expected in the dust separation listed as the scope of the known vortex chamber.

Opfindelsen har derimod til hensigt at tilvejebringe en forbedring 20 af udskillelsen af væsker fra en væske-gasblanding, således som det finder sted i Dampkraftværker ved kapaciteter mellem hundrede og tusind tons pr. time. En til dette formål anvendt cyklonudskiller er fx. vist i tidsskriftet "VGB-Kraftwerkstechnik", hæfte 12, dec. 1973 i artiklen "Kessel und Feuerungen fur 600-MW-Blocke fur Braunkohle", siderne 772 25 til 791 på billede 13. Den omfatter et cylindrisk hus, i hvis øvre område der er anbragt tilnærmelsesvis tangentialt forløbende indløbsstudse, som munder ud i et horisontalt plan. De hælder svagt i forhold til dette plan, således at væsken, som afsættes i indløbsstudsene, kan løbe ind i udskilleren.The invention, on the other hand, is intended to provide an improvement in the separation of liquids from a liquid-gas mixture, as occurs in steam power plants at capacities between one hundred and one thousand tonnes per annum. hour. A cyclone separator used for this purpose is e.g. shown in the journal "VGB-Kraftwerkstechnik", booklet 12, dec. 1973 in the article "Kessel und Feuerungen fur 600-MW-Blocke fur Braunkohle", pages 772 25 to 791 in picture 13. It comprises a cylindrical housing, in the upper region of which is arranged approximately tangentially extending inlet, which opens into a horizontal level. They incline slightly relative to this plane so that the liquid deposited in the inlet nozzles can flow into the separator.

30 En udløbsledning, som ligger i udskillerens rotationsakse, er an bragt på den nederste endeflade af det cylindriske hus. Ovenover sidder en plade, som er anbragt på indervæggen af huset med vertikale ribber.An outlet line located in the axis of rotation of the separator is disposed on the lower end surface of the cylindrical housing. Above is a plate which is placed on the inner wall of the housing with vertical ribs.

Dette er en såkaldt hvirvelbryder, idet ribberne virker som en lodret ledeindretning, med hvilken rotationsenergien i den udløbende væske 35 mindskes. Derved skal det opnås, at væsken ikke river nogle gasser med - 2 -This is a so-called vortex breaker, the ribs acting as a vertical conductor with which the rotational energy of the flowing liquid 35 is reduced. In this way it must be achieved that the liquid does not discharge any gases with - 2 -

sig.themselves.

Til grund for den foreliggende opfindelse ligger den opgave at forbedre virkningsgraden af cyklonudskilleren, da det har vist sig, at der til trods for de vertikale ledeindretninger rives gas med hen til 5 væskeudløbet, hvor gassen forhindrer væskeudløbet i form af en piskeformet gasblærehvirvel.The object of the present invention is to improve the efficiency of the cyclone separator as it has been found that, despite the vertical guide devices, gas is shredded to the liquid outlet, where the gas prevents the liquid outlet in the form of a whip-shaped gas bladder swirl.

Ifølge opfindelsen foreslås det, at pladen med henblik på udskillelse af væske fra en væske-gasblanding via et væskeudløb er anbragt i den nedre ende af huset og er forsynet med lodrette ledeindretninger, 10 som omslutter røret, at diameteren af røret andrager 1/10 til 1/30 af bredden af pladen, og at røret rager op over pladen med mindst det dobbelte af sin diameter.According to the invention, it is proposed that the plate for separating liquid from a liquid-gas mixture via a liquid outlet is disposed at the lower end of the housing and is provided with vertical guide devices 10 enclosing the pipe, the diameter of the pipe being 1/10 to 1/30 of the width of the plate, and that the tube protrudes above the plate by at least twice its diameter.

Med opfindelsen kan der opnås en forbavsende forbedring af udskillerens virkningsgrad. Ved forsøg har det klart vist sig, at pisken, 15 altså den med væsken medrevne gassøjle i udskillerens akse, fuldstændigt kan undgås. Røret, som rager op over plade med mindst det dobbelte af sin diameter, udøver herved en vis "skorstensvirkning".The invention provides an astonishing improvement in the efficiency of the separator. In experiments, it has clearly been found that the whip, that is, the gas column included with the liquid in the axis of the separator, can be completely avoided. The tube, which projects above a plate with at least twice its diameter, thus exerts a certain "chimney effect".

Den frie længde af røret, altså dets højde over pladen kan hensigtsmæssigt andrage mindst 1/10 af diameteren af udskillerhuset om-20 kring pladen. Dermed kan det opnås, at mundingen af røret ligger oven over det normale vandspejl i udskilleren. Forsøg har imidlertid vist, at der også indtræder en væsentlig forbedring af udskillerens virkningsgrad, hvis blot røret ender under vandspejlet.The free length of the tube, i.e. its height above the plate, may conveniently be at least 1/10 of the diameter of the separator housing around the plate. Thus, it can be achieved that the mouth of the pipe is above the normal water level in the separator. However, tests have shown that a significant improvement in the efficiency of the separator also occurs if the pipe ends below the water level.

Til nærmere forklaring af opfindelsen beskrives et udførelsesek-25 sempel ved hjælp af den medfølgende tegning. Figuren viser et lodret snit gennem en skematiseret udskillerraodel ifølge opfindelsen til adskillelse af en damp-vandblanding.For a further explanation of the invention, an exemplary embodiment is described by means of the accompanying drawing. The figure shows a vertical section through a schematic separator root according to the invention for separating a steam-water mixture.

Cyklonudskilleren omfatter et cylindrisk hus 1, som er lukket i den øvre endeflade med en øvre lågplade 2. Lågpladen 2 er en plan cir-30 kelskive med en diameter D på fx. 600 mm til anvendelse i dampkraftværker, til hvilke opfindelsen først og fremmest er tænkt. Midt i pladen 2 sidder dampudløbsrøret 3, således at dampen kan undvige i retning af pilen 4 opad til. I en afstand mellem 0,8 og 1,5 D under lågpladen 2 ligger det stiplet antydet indtrædningsplan 5 for de tangentialt an-35 bragte indløbsstudse 6. Gennem disse tilføres vand-dampblandingen iThe cyclone separator comprises a cylindrical housing 1 which is closed in the upper end surface by an upper cover plate 2. The cover plate 2 is a flat circular disc having a diameter D of e.g. 600 mm for use in steam power plants to which the invention is primarily intended. In the middle of the plate 2 is the steam outlet pipe 3, so that the steam can evade in the direction of the arrow 4 upwards. At a distance of 0.8 to 1.5 D below the cover plate 2, the dotted indicated entry plane 5 of the tangentially arranged inlet nozzles 6 lies.

- 3 - retning af pilen 7. Der dannes en roterende strømning, hvor væskeoverfladen i udskilleren har en parabolsk form med den punkteret viste overflade 8. Det dybeste punkt 4 af vandspejlet er antydet ved 9.- 3 - direction of the arrow 7. A rotating flow is formed, the liquid surface of the separator having a parabolic shape with the punctured surface shown 8. The deepest point 4 of the water level is indicated by 9.

Den nederste endeflade på cyklonudskilleren er ligeledes lukket 5 med en plan, cirkelformet plade 12. Midt i pladen er væskeudløbet 13 anbragt, således at væsken kan udtrækkes i retning af pilen 14.The lower end surface of the cyclone separator is also closed 5 with a flat circular plate 12. In the middle of the plate, the liquid outlet 13 is arranged so that the liquid can be drawn in the direction of the arrow 14.

Neden under vandspejlet 9 er der omtrent i afstanden 0,8 til 1,5 D fra pladen 12 anbragt en plan plade 16 som vertikal ledeindretning på indersiden af huset, der med sin ydre rand ligger på en cirkel, og som 10 har vertikale boringer 17. Boringerne 17 fremtvinger på grund af deres i forhold til diameteren omtrent dobbelt så store længde et vidtgående vertikalt forløb af det gennemløbne vand, således at hvirvelen er væsentligt formindsket i rummet neden under pladen 16.Below the water level 9, approximately a distance of 0.8 to 1.5 D from the plate 12 is arranged a flat plate 16 as a vertical guide device on the inside of the housing, which with its outer edge lies on a circle and 10 has vertical bores 17 The bores 17, because of their relative length about twice the length, force a longitudinal vertical course of the flowing water, so that the vortex is substantially reduced in the space below the plate 16.

Et rør 21 er indsat i pladen 16, hvorunder det forløber i rota-15 tionsaksen, som er vist på figuren ved hjælp af den stiplede rette linie 20. Røret 21 har ved en pladediameter på 600 mm et cirkeltværsnit med en diameter på 50 mm. Dets længde andrager med 300 mm omtrent 50% af pladediameteren. Røret 21 er en af trækningsmulighed for den af vandet medrevne damp, som på grund af trykforholdene i udskilleren har en 20 væsentlig forbedring af udskillerens virkningsgrad til følge. I hvert tilfælde er den tidligere iagttagede pisk omkring væskeudløbet 13 fuldstændigt fjernet.A tube 21 is inserted into the plate 16, below which it extends into the axis of rotation, which is shown in the figure by means of the dashed straight line 20. The tube 21 has a circular cross section with a diameter of 50 mm at a plate diameter of 600 mm. Its length is 300 mm, approximately 50% of the plate diameter. The pipe 21 is one of drawable for the steam entrained by the water which, due to the pressure conditions in the separator, has a significant improvement in the efficiency of the separator. In each case, the previously observed whip around the liquid outlet 13 is completely removed.

Ved det skematisk gengivne udførelseseksempel er røret 21 ført gennem pladen 16. Røret 21 kan imidlertid også sættes på pladen, så-25 ledes at der i pladen blot skal være en boring, som stemmer overens med røret 21. Normalt har et indsat rør imidlertid en større mekanisk styrke, således at svingningsforekomster kan undgås.In the schematically illustrated embodiment, the pipe 21 is passed through the plate 16. However, the pipe 21 can also be mounted on the plate, so that in the plate there must be only a bore which corresponds to the pipe 21. Normally, however, an inserted pipe has a greater mechanical strength so that oscillation occurrences can be avoided.
