Den foreliggende opfindelse angår en vandudskiller til gas eller damp med et rundtgående rum med rotationsskovle eller skrånende vægge til i rotationsætning af gassen eller dampen anordnet mellem et cylindrisk skillevægsorgan og et 5 hus, og hvor rotationsskovlene eller de skrånende vægge er anordnet til indsnævrende forløb i radial retning af det rundtgående rum, og hvor det rundtgående rum og en indvendig boring i skillevægsorganet er forbundet med en ventiltilgang, en afløbsventildel og en ventilafgang.BACKGROUND OF THE INVENTION The present invention relates to a gas or vapor water separator having a circular space with rotating vanes or inclined walls for rotating the gas or vapor arranged between a cylindrical partition member and a housing, and the rotary vanes or inclined walls being arranged for narrowing radially. direction of the circumferential space, and wherein the circumferential space and an internal bore in the partition means are associated with a valve inlet, a drain valve member and a valve outlet.
10 En vandudskiller af denne art er beskrevet i britisk patentskrift nr. 1,481,126 og tjener til bortledning af kondenseret vand i gas- og f.eks. tryklufts- og dampledninger udad bort under indvirkning af en centrifugalkraft, der er bragt til indvirkning ved hjælp af en strømningsrotation.A water separator of this kind is described in British Patent Specification No. 1,481,126 and serves to drain condensed water into gas and e.g. compressed air and steam lines outwardly under the influence of a centrifugal force brought into action by a flow rotation.
15 I denne art gas-vand-udskiller roteres transportatet i en øvre del inde i et hus, og vanddråber, der er indeholdt i gassen, slynges ud til ydersiden ved virkningen af den resulterende centrifugalkraft og udskilles derved. Gassen eller luftarten afgives til en ventilafgangsside, medens de 20 udskilte vanddråber afgives til husets omgivelser gennem en afløbsventil, der er anbragt i en nederste del inde i huset.In this type of gas-water separator, the transport is rotated in an upper part inside a housing, and water droplets contained in the gas are thrown out to the outside by the effect of the resultant centrifugal force and are thereby separated. The gas or gas is delivered to a valve outlet side, while the 20 separated water droplets are delivered to the housing environment through a drain valve located in a lower portion within the housing.
Den kendte vandudskiller er indrettet med et cylindrisk skillevægsorgan anbragt i en øvre del inde i huset 25 til dannelse af et rundtgående rum mellem skillevægsorganet og husvæggen. I dette rundtgående rum er der anbragt rotationsskovle eller ledeflader, medens skillevægsorganets rundtgående rum og en indvendig boring står i forbindelse med en ventiltilgang, en afløbsventildel og en ventilafgang.The known water separator is provided with a cylindrical partition member arranged in an upper part inside the housing 25 to form a circumferential space between the partition member and the housing wall. In this circumferential space, rotating vanes or guide surfaces are provided, while the circumferential space of the partition means and an internal bore are associated with a valve access, a drain valve member and a valve outlet.
30 X denne konstruktion sættes transportatet, der strømmer til via ventiltilgangen, i rotation i det rundtgående rum, således at vanddråberne under centrifugalkraft-indvirkning slynges udad. De således udskilte vanddråber strømmer ned og afgives til omgivelserne gennem afløbsventilen. I en 35 central del af den roterende strømning strømmer gassen mod 230 x this construction, the conveyor flowing through the valve inlet is rotated in the circumferential space so that the water droplets are thrown outwards under centrifugal force. The water droplets thus separated flow down and are released to the surroundings through the drain valve. In a central portion of the rotary flow, the gas flows toward 2

ventilafgangssiden gennem den indvendige boring i skillevægsorganet. Spiralvæggéne er anordnet sålédes, at deres begyndelses- og endekanter forløber lodret, hvad der indebærer, at også spiralvæggenes yderflader forløber lodret i 5 det samlede område, og således foreligger der alene i omkredsretning et tværsnitsindsnævrende forløb. Spiralvæggenes lodrette endekanter strækker sig i omkredsretning ud over rotationsskovlenes eller de skrånende vægges endekanter, således at der i omkredsretning foreligger en radial 10 afrivningskant for rotationsskovlene eller de skrånende vægge og endvidere forsat en lodret afrivningskant for spiralvæggene.valve outlet side through the inner bore of the partition member. The spiral walls are arranged so that their beginning and end edges extend vertically, which means that also the outer surfaces of the spiral walls extend vertically in the total area, and thus there is a cross-section narrowing only in circumferential direction. The vertical end edges of the spiral walls extend circumferentially beyond the end edges of the rotary vanes or sloping walls, so that there is a radial tear edge for the rotary vanes or slopes and in addition, a vertical tear edge for the spiral walls is provided.
Det har endvidere vist sig, at ved denne kendte vandudskiller bliver vanddråberne, selv ved en kraftig rota-15 tion, kun delvis underkastet centrifugering udad, og derfor er vandudskilnings-graden begrænset. Grunden hertil er, at processen hovedsagelig hviler på den naturlov, at når et strømningsmedium underkastes rotation, tvinges strømnings-mediet mere udefter under indvirkning af en 20 centrifugalkraft, desto større dens masse er, således at meget små vanddråber føres indad fra radialt yderst til radialt inderst langs overfladen og som følge heraf føres til ventilens afgångsside sammen med gassen eller luftarten.Furthermore, it has been found that in this known water separator, the water droplets, even with a strong rotation, are only partially subjected to outward centrifugation and therefore the degree of water separation is limited. The reason for this is that the process is mainly based on the law of nature that when a flow medium is subjected to rotation, the flow medium is forced outward more under the action of a centrifugal force, the greater its mass, so that very small water droplets are fed inward from radially outermost to radially innermost along the surface and as a result are passed to the outlet side of the valve together with the gas or gas.
Den foreliggende opfindelse har derfor til opgave ved 25 en vandudskiller af den angivne art at forbedre graden af vandudskillelse.Therefore, the present invention has the object of providing a water separator of the kind specified to improve the degree of water separation.
Løsningen heraf er baseret på den tanke, at indfange vanddråber og direkte at slynge dem udad, og løsningen ifølge den foreliggende opfindelse består i ved en vandud-30 skiller af den indledningsvis angivne art, at den radiale udstrækning af spiralvæggene fra skillevægsorganets yderside forløber gradvist tiltagende i aksial retning fra de skrånende vægges tilgangssidigt øvre ender, og at spiralvæggenes sammen med de skrånende vægges afgangssidigt nedre 35 ender forløber endende i en fælles trinformet radialt ori-The solution thereof is based on the idea of capturing water droplets and directly tossing them outwards, and the solution according to the present invention consists in a water separator of the type indicated in the preamble, that the radial extension of the spiral walls from the outside of the partition member gradually increases in axial direction from the approach side upper ends of the inclined walls, and that the spiral walls together with the downwardly lower ends of the inclined walls extend terminally in a common step-shaped radial orientation.

I overensstemmelse hermed forløber ved en vandudskiller ifølge opfindelsen de skråt nedad hældende ribber i det rundtgående rum mellem skillevægsorgan-cylinderen og 5 husvæggen således, at transportatets bevægelsesretning ved gennemstrømning af det rundtgående rum indstiller sig svarende til de skrånende vægges forløb. Følgelig roterer transportatet i det rundtgående rum på grund af dets kontinuitet, og denne rotation udstrækker sig til over og under 10 de skrånende vægge, dvs. at transportatet trænger ind i det rundtgående rum under rotation og også udtræder af dette under rotation.Accordingly, in the case of a water separator according to the invention, the inclined downward sloping ribs in the circumferential space between the partition member cylinder and the housing wall extend so that the direction of movement of the conveyance as flowing through the circumferential space aligns with the course of the inclined walls. Accordingly, because of its continuity, the transport rotates in the circumferential space and this rotation extends to above and below the sloping walls, i.e. that the conveyor enters the orbital space during rotation and also exits from it during rotation.
Eftersom spiralvæggene rager gradvist udefter fra de skrånende vægges øverste ender til de nederste ender, føres 15 transportatet mere radialt udad end det, der svarer til en retning tangentialt til det rundtgående rum og blæses i en bedre tilstand mod en indervæg af et hus anbragt radialt udvendigt. Eftersom bredden af det rundtgående rum endvidere bliver mindre i retning mod de nederste ender fra de ø-20 verste ender af de skrånende vægge, vokser det roterende transportats hastighed gradvist og når et maksimum ved den nederste endevæg.Since the spiral walls extend outwardly from the upper ends of the sloping walls to the lower ends, the transport is moved more radially outward than that corresponding to a direction tangentially to the circumferential space and is blown in a better condition against an inner wall of a radially exterior housing. . Furthermore, as the width of the circumferential space becomes smaller towards the lower ends from the upper ends of the sloping walls, the speed of the rotating conveyor gradually increases and reaches a maximum at the lower end wall.
Eftersom spiralvæggene endvidere er forbundet trinvist med de radiale endevægge ved de skrånende vægges nederste 25 ender, udvides bredden af det rundtgående rum pludselig ved disse endevægsdele. Når transportatet roteres, falder trykket nær endevæggene som følge deraf, og vanddråberne, der sidder på vægoverfladerne i nærheden, samler sig ved forbindelseskanterne mellem spiralvæggene og endevæggene og blæses 30 derefter af af den stærkt roterende strøm, hvis hastighed i har nået sit maksimum ved forbindelseskantdelene som tidligere omtalt og blæses mod det radialt udenfor anbragte hus' indervæg.Furthermore, since the coil walls are incrementally connected to the radial end walls at the lower ends of the sloping walls, the width of the circumferential space is suddenly expanded at these end wall portions. As the transport is rotated, the pressure near the end walls decreases as a result, and the water droplets sitting on the adjacent wall surfaces accumulate at the connection edges between the spiral walls and the end walls, and are then blown off by the highly rotating current whose velocity has reached its maximum at the connection edge portions. as previously discussed and blown against the inner wall of the housing radially outside.
Opfindelsen medfører følgende særlige virkninger: 4The invention has the following special effects:
DK 163568BDK 163568B
Ikke blot udføres en gas-vand-udskillelse ved virkningen af en centrifugalkraft induceret af transportatrotatio-nen; men også vanddråber samles effektivt ved forbindelses-kanterne mellem spiralvæggene og endevæggene, og den roteren-5 de strøms hastighed opnår størsteværdien ved nævnte kantdele til at blæse vanddråber fra disse dele og forårsage, at de blæses mod det radialt udenfor anbragte hus1 indervæg. Som følge heraf er gas-vand-udskillelseseffektiviteten særdeles høj.Not only is a gas-water separation effected by the action of a centrifugal force induced by the transport rotation; but also water droplets are efficiently collected at the connecting edges between the spiral walls and the end walls, and the velocity of the rotating current achieves the greatest value at said edge portions to blow water droplets from these portions and cause them to be blown against the radially outside housing inner wall. As a result, the gas-water separation efficiency is extremely high.
10 Det drejer sig ikke blot om at forøge den roterende strøms hastighed, men også om at gøre det rundtgående rums bredde mindst mulig ved de skrånende vægges nederste endedele for derved at få den roterende strøms hastighed størst mulig på vigtige steder, nemlig ved de skrånende vægges ne-15 derste endedele. Derfor er den roterende strøm forholdsvis svag før og efter disse dele og forhindrer derved vanddråber i at føres til afgangssiden sammen med gassen eller forhindre vandoverfladen ved afløbsventildelen i at forstyrres og forårsage en fejlfunktion for afløbsventilen.10 It is not only a matter of increasing the speed of the rotating current, but also of making the width of the surrounding space as small as possible at the lower end portions of the inclined wall, so as to get the speed of the rotating current as high as possible in important places, namely at the inclined walls. lower end parts. Therefore, the rotary flow is relatively weak before and after these parts, thereby preventing water droplets from being passed to the outlet side with the gas or preventing the water surface at the drain valve portion from being disturbed and causing a drain valve malfunction.
20 Hvis det følgende tages i betragtning ved udøvelse af den foreliggende opfindelse, vil der opnås bedre funktion og en bedre virkning.If the following is taken into account in the practice of the present invention, better function and effect will be obtained.
Særlig fordelagtig er det, og der opnås endvidere en høj udskillelsesgrad, hvis ..på skillevægsorganets yderside 25 der er anordnet langsgående vægge, der strækker sig opad-forløbende fra de skrånende vægges øvre ender. Herved vil gas, der træder ind i det rundtgående rum træffe mod de langsgående vægge, således at også vanddråberne delvis træffer mod de langsgående vægge og forbliver anhæftende 30 der og på denne måde udskilles fra gassen.It is particularly advantageous, and a high degree of separation is also obtained if longitudinal walls extending upwardly from the upper ends of the inclined walls are arranged on the outer side of the partition member 25. Hereby, gas entering the circumferential space will impinge on the longitudinal walls so that the water droplets also partially impinge on the longitudinal walls and remain adherent there and in this way are separated from the gas.
Er i det mindste en yderoverflade på skillevægsorganet, hvortil også hører de skrånende vægge og spiralvæggene eller rotationsskovlene, indrettet med en maksimal ruhedsdyb-de på 15 - 50 jum, da hæfter vanddråberne lettere til disse 35 flader, og hastigheden af den roterende strøm deceleres i moderat omfang i nærheden af vægoverfladen og gør det så-Is at least one outer surface of the partition member, including the inclined walls and the spiral walls or rotating vanes, arranged with a maximum roughness depth of 15 - 50 µm, since the water drops are more easily adhered to these 35 surfaces and the speed of the rotating current is decelerated. moderate extent near the wall surface and so does-

5 ledes muligt at fange vanddråber på vægoverfladen.5, it is possible to catch water droplets on the wall surface.
De således på vægoverfladen fangede vanddråber samles ved de forbindende kantdele som tidligere beskrevet og blæses mod det omsluttende hus' indervæg. Således kan 5 vanddråber udskilles fra gas ved at hæfte til en vægoverflade med den nævnte ruhed.The water droplets thus caught on the wall surface are collected at the connecting edge portions as previously described and blown against the inner wall of the enclosing housing. Thus, 5 drops of water can be separated from gas by adhering to a wall surface of said roughness.
Hvis den ydre periferi af en nederste endedel af skillevægsorganet i nedadgående retning forløber gradvist radialt udad til indsnævring af skillevægsdelens 10 afstand fra det omsluttende hus' inderside, får den roterende strøm yderligere forøget sin hastighed og udskiller vand fra gas og blæses igen mod det omsluttende hus's inderste væg. I dette tilfælde kan en ønsket funktion og virkning opnås, hvis hældningsvinklen for 15 skillevægsdelen ved sin nederste endedels yderste omkreds i forhold til en lodret retning eller ventilakse-retning, får en værdi i området 25-30 vinkelgrader. Især hvis en sådan hældningsvinkel bliver 35 vinkelgrader, vil de bedste resultater opnås.If the outer periphery of a lower end portion of the partition member extends downwardly radially outwardly to narrow the distance of the partition part 10 from the inside of the enclosing housing, the rotating current further increases its velocity and separates water from gas and is again blown toward the enclosure. inner wall. In this case, a desired function and effect can be obtained if the angle of inclination of the partition portion at its outermost outer circumference relative to a vertical or valve axis direction is given a value in the range of 25-30 angular degrees. Especially if such an angle of inclination becomes 35 degrees, the best results will be obtained.

Som vist i større målestokforhold i fig. 2-4 er rotationsskovlbladene 38 hver sammensat af en langsgå-15 ende væg 39, som rager radialt udad fra en øverste ende af skillevægsorganets 34 indre cylindérrør til en øverste ende af dens yderste cylinderrør, en skrånende væg 40, som hælder skråt nedad fra en nederste ende på den langsgående væg 39 på et sted beliggende mellem det 20 yderste og det inderste cylinderrør, og en spiralvæg 41 udformet ved en øverste overflade på den skrånende væg 40 forløbende i spiralform fra det inderste cylinderrør i retning mod det yderste cylinderrør. Fem rotationsskovlblade 38 er udformet i det rundtgående rum 37. En 25 afsluttende ende af spiralvæggen 41 er forbundet trinvist til en radialt forløbende endevæg 42.As shown in larger scale conditions in FIG. 2-4, the rotary vane blades 38 are each composed of a longitudinal end wall 39 which projects radially outwardly from an upper end of the inner cylinder tube of the partition member 34 to an upper end of its outer cylinder tube, a sloping wall 40 inclined downwardly from a the lower end of the longitudinal wall 39 at a location located between the outermost and the inner cylinder tubes, and a spiral wall 41 formed at an upper surface of the inclined wall 40 extending in spiral form from the innermost cylinder tube towards the outermost cylinder tube. Five rotary vane blades 38 are formed in the circumferential space 37. A terminating end 25 of the spiral wall 41 is incrementally connected to a radially extending end wall 42.
Den nederste del af den indvendige cylinder af skillevægsorganet 34 udvider sig gradvist nedefter og ender i nærheden af og med en forud fastlagt afstand fra 30 den udvendige cylinders indre væg. Dens vinkel Θ i forhold til en vertikal retning er 35°. Hvis hældningsvinklen Θ er indstillet i området 25-50°, vil der opnås en god vandudskilningsvirkning.The lower part of the inner cylinder of the partition member 34 gradually expands downward and ends in the vicinity of and at a predetermined distance from the inner wall of the outer cylinder. Its angle Θ with respect to a vertical direction is 35 °. If the angle of inclination Θ is set in the range of 25-50 °, a good water separation effect will be obtained.

9 sfærisk flyder 43 er anbragt inde i udskillerkammeret 7.9 spherical float 43 is arranged inside the separator chamber 7.
I bunddækslet 9 er et afløbsventilsæde 44 fastgjort ved den inderste ende af en af løbsstuts 45. Flyderen 43 er dækket med et flyderdække 46, der har en forbindel-5 sesåbning 47 udformet i sin underste del. Henvisningsnummer 48 betegner en udluftningsåbning i den øverste del af flyderdækket 46.In the bottom cover 9, a drain valve seat 44 is secured to the innermost end of one of the drain plug 45. The float 43 is covered with a float cover 46 having a connecting opening 47 formed in its lower part. Reference numeral 48 denotes a vent opening in the upper portion of the float deck 46.
Transportat, som tilføres fra ventiltilgangsporten 22, bringes i rotation af de skrånende vægge 40 på rota-10 tionsskovlbladene 38. Vanddråber, der er indeholdt i transportatet, rystes ud og udskilles ved virkningen af en centrifugalkraft. De langsgående vægge 39 tillader det indstrømmende transportat at ramme sig vinkelret og modvirke den roterende strøm, der dannes af de skrånende 15 vægge 40 for at nedsætte strømningshastigheden af den roterende strøm og rette den mere nedefter. På dette tidspunkt rammer en del vanddråber de langsgående vægge 39 og hæfter til disses overflader.Transportat which is supplied from the valve access port 22 is rotated by the sloping walls 40 of the rotary vane blades 38. Water droplets contained in the transportat are shaken out and separated by the action of a centrifugal force. The longitudinal walls 39 allow the flowing conveyor to strike perpendicularly and counteract the rotating current formed by the sloping walls 40 to decrease the flow rate of the rotating current and direct it further downward. At this point, some water drops hit the longitudinal walls 39 and adhere to their surfaces.
Spiralvæggene 41 tjener til at rette den roterende 20 strøm mere radialt udad end en tangential retning i det rundtgående rum 37. Ved de nederste ender af de skrånende vægge 40 bliver bredden af det rundtgående rum 37 minimal, og strømningshastigheden bliver maksimal. Eftersom de afsluttende ender af spiralvæggende 41 er 25 forbundet trinvist til de radialt forløbende endevægge 42, forøges bredden af det rundtgående rum 37 pludselig med forbindelseskantdelene mellem spiralvæggene 41 og endevæggene 42 som en afgrænsning. Når transportatet roterer, reduceres følgelig områderne nær endevæggene 30 42 i tryk, og vanddråber, der hæfter til vægoverfladen, samles ved forbindelseskantdelene. De således samlede vanddråber blæses bort fra forbindelseskantdelene af den kraftigt roterende strøm og blæses imod husets 8 inder-væg og også imod skillevægslegemets 34 ydre cylinderrørs 35 indervæg.The spiral walls 41 serve to direct the rotating 20 more radially outward than a tangential direction in the circumferential space 37. At the lower ends of the inclined walls 40, the width of the circumferential space 37 becomes minimal and the flow rate becomes maximum. Since the final ends of spiral wall 41 are connected stepwise to the radially extending end walls 42, the width of the circumferential space 37 is suddenly increased with the connecting edge portions between the spiral walls 41 and the end walls 42 as a boundary. Accordingly, as the transport rotates, the areas near the end walls 30 42 are reduced in pressure and water droplets adhering to the wall surface are collected at the connecting edge portions. The water droplets thus collected are blown away from the connecting edge portions of the strongly rotating stream and blown against the inner wall of the housing 8 and also against the inner wall of the partition body 34 of the partition body 34.

Gassen, som har passeret skillevægsorganets 34 nederste ende, passerer indersiden deraf og strømmer imod reduktionsventilens B hovedventil 5 og strømmer ud til ventilafgangsporten 23, medens det 5 udskilte vand strømmer ind til flyderdækkets 46 indre via forbindelsesåbningen 47. På dette tidspunkt udtræder den gas, der er til stede i det indre af flyderdækket 46, gennem udluftningsåbningen 48. Flyderen 43 bevæger sig op og ned i afhængighed af vandstand til åbning og 10 lukning af afløbsventilsædets 44 afløbsventilport 45 og tillader kun vand at afgives til omgivelserne fra af-løbsporten 45.the inner circumferential wall of the partition member 34 and the door 8 of the housing 8. The gas which has passed the lower end of the partition member 34 passes through the inside thereof and flows against the main valve 5 of the reducing valve B and flows out to the valve outlet port 23, while the 5 separated water flows into the interior of the float tire 46 via the connection opening 47. At this point, the gas leaving the is present in the interior of the float tire 46, through the vent opening 48. The float 43 moves up and down depending on the water level for opening and closing of the drain valve seat 44 drain valve port 45 and allows only water to be discharged to the environment from the drain port 45.
