Description

lO l5 20 25 30 35 8092770-9 Detta syfte uppnås genom att anordningen enligt upp- finningen erhållit de i de följande patentkraven angivna kännetecknen. lO l5 20 25 30 35 8092770-9 This object is achieved by the device according to the invention having the features set forth in the following claims.

Utföringsformer av blandningsanordningen enligt upp- finningen kommer i det följande att beskrivas i samband med ritningarna. Fig. l visar därvid schematiskt i perspektiv en blandningsanordning eller ett blandningsdon enligt upp- finningen insatt i ett kanalsystem. Fig. 2 visar en planvy av donet i fig. l.

Fig. 6 visar en ändrad utföringsform av ett don liknande det i fig. 5.Embodiments of the mixing device according to the invention will be described in the following in connection with the drawings. Fig. 1 shows schematically in perspective a mixing device or a mixing device according to the invention inserted into a duct system. Fig. 2 shows a plan view of the device in Fig. 1. Fig. 3 shows a plan view similar to Fig. 2 of a modified embodiment. Fig. 4 shows in perspective a mixing device with throttling devices for regulating the flow through the device. Fig. 5 shows a plan view of a mixing device provided with a pressure equalizing device. Fig. 6 shows a modified embodiment of a device similar to that in Fig. 5.

Den i fig. l visade utföringsformen av blandningsdonet l0 enligt uppfinningen innefattar ett antal grundenheter in- nefattande ett vellat ark l2 som är anbringat mot ett plant ark l4 och därvid bildar s.k. enkelvell. Varannan sä fram- ställd grundenhet eller enkelvell l0, l2 placeras i vinkel, exempelvis såsom visas i fig. l i rät vinkel, i förhållande till intilliggande grundenhet eller enkelvell l0, l2. De av de vellade skiktens korrugeringar bildade, raka kanalerna kommer sålunda att omväxlande förlöpa i två mot varandra vinkelräta riktningar genom hela höjden av blandningsdonets l0 kropp såsom anges med pilarna l6, l8,i fig. l och 2. Ge- nom att donets l0 grundenheter ges en tresidig, företrädes- vis triangulär form, som bäst framgår av fig. 2, med triang- elns kortsidor vinkelräta mot de vellade skiktens korruge- ringar erhålles tvâ system av raka genomgående kanaler där kanalerna i respektive system från var sin separat inlopps- sida A resp. B passerar åtskilda från det andra systemets kanaler till en utloppssida C av blandningsdonet där kana- lerna mynnar gemensamt och med en jämn fördelning av de bå- da systemens kanalmynningar över utloppssidans C yta.The embodiment of the mixing device 10 according to the invention shown in Fig. 1 comprises a number of basic units comprising a corrugated sheet 12 which is applied to a flat sheet 14 and thereby forms so-called single corrugations. Every other basic unit or single corrugation 10, 12 thus produced is placed at an angle, for example as shown in Fig. 1 at a right angle, in relation to the adjacent basic unit or single corrugation 10, 12. The straight channels formed by the corrugations of the corrugated layers will thus run alternately in two mutually perpendicular directions through the entire height of the body of the mixing device 10 as indicated by the arrows 16, 18, in Figs. 1 and 2. By giving the basic units of the device 10 a three-sided, preferably triangular shape, as best shown in Fig. 2, with the short sides of the triangle perpendicular to the corrugations of the corrugated layers, two systems of straight continuous channels are obtained where the channels in each system from their separate inlet side A and B respectively pass separately from the channels of the other system to an outlet side C of the mixing device where the channels open together and with an even distribution of the channel openings of both systems over the surface of the outlet side C.

I den i fig. l och 2 på ritningarna visade utförings- formen är till blandningsdonets l0 inloppssidor A och B anslutna två separata tillförselkanaler 20, 22 för tillför- l0 15 20 25 30 35 8002770-9 sel av två strömmar av de medier som skall blandas till do- net l0 och en kanal 24 som leder strömmen av de blandade medierna vidare. Mediernas strömningsriktning är därvid schematiskt angiven med pilar i figurerna. Även om bland- ningsdonet 10 kan användas för blandning av alla strömmande medier exempelvis vätskor, gaser etc. kommer fortsättnings- vis beskrivningen för enkelhetens skull att hänföras till blandning av olika luftströmmar exempelvis för temperatur- utjämning i samband med ventilationsanläggningar.In the embodiment shown in Fig. 1 and 2 of the drawings, two separate supply channels 20, 22 are connected to the inlet sides A and B of the mixing device 10 for supplying two streams of the media to be mixed to the device 10 and a channel 24 which conducts the stream of the mixed media further. The flow direction of the media is then schematically indicated by arrows in the figures. Although the mixing device 10 can be used for mixing all flowing media, for example liquids, gases, etc., the description will hereinafter, for the sake of simplicity, be referred to mixing different air streams, for example for temperature equalization in connection with ventilation systems.

De i blandningsdonets l0 två kanalsystem passerade luftströmmarna kommer, då kanalerna mynnar gemensamt vid den triangelformade kroppens långsida, att blandas vid ut- trädet ur donet 10, som anges med pilarna l6, 18. Eftersom kanalmynningarna som nämnts är jämntfördeladeöver hela donets 10 utloppssida såväl i längd- som höjdled är det klart att blandningen av medierna såsom luftströmmarna blir mycket fullständig och effektiv p g a det stora antalet små kanaler i det att vardera av de båda medierna såsom luft- strömmarna distribueras över hela utloppsytan.The air streams passed through the two channel systems of the mixing device 10 will, when the channels open together at the long side of the triangular body, be mixed at the exit from the device 10, which is indicated by arrows 16, 18. Since the channel openings as mentioned are evenly distributed over the entire outlet side of the device 10 both longitudinally and vertically, it is clear that the mixing of the media such as the air streams becomes very complete and efficient due to the large number of small channels in that each of the two media such as the air streams is distributed over the entire outlet surface.

Blandarens l0 grundkropp eller enkelvell innefattar i omväxlande plana l4 och vellade l2 skikt som är anbringade mot varandra. De relativt tunna skikten är därvid lämpligen framställda av plast, mineralfibermaterial, exempelvis glas- fibermaterial, metalliska material såsom aluminium, rost- fritt stål etc. eller andra liknande material beroende på den omgivning i vilken blandningsdonet l0 används. Vell- höjden väljes därvid relativt stor för att erhålla ett litet friktionstryckfall. Donet l0 framställes lämpligen genom att rektangulära eller kvadratiska grundenheter av enkelvell staplas på varandra till önskad höjd och förbindes medelst lim- ning, svetsning eller liknande, varefter den önskade triangu- lära formen uttages genom diagonal delning av den kvadratiska eller rektangulära kroppen så att åtminstone två triangulära blandardon erhålles. Naturligtvis är det tänkbart att blandar- kroppen kan ha en från den rent tresidiga formen med raka sidor avvikande form och att kroppar med såväl tresidig form som 10 15 20 25 30 8ÜÛ277Û~9 annan form kan framställas genom separat tillskärning av varje enkelvellskikt av vilken kroppen är sammansatt.The basic body or single wave of the mixer 10 comprises alternating flat l4 and waved l2 layers which are applied to each other. The relatively thin layers are then suitably made of plastic, mineral fibre material, for example glass fibre material, metallic materials such as aluminium, stainless steel etc. or other similar materials depending on the environment in which the mixing device 10 is used. The wave height is then selected to be relatively large in order to obtain a small friction pressure drop. The device 10 is suitably made by stacking rectangular or square basic units of single wave on top of each other to the desired height and connecting them by means of gluing, welding or the like, after which the desired triangular shape is taken out by diagonally dividing the square or rectangular body so that at least two triangular mixing devices are obtained. Of course, it is conceivable that the mixer body may have a shape that deviates from the purely three-sided shape with straight sides and that bodies with both a three-sided shape and another shape can be produced by separately cutting each single layer of which the body is composed.

Vid den i fig. 3 visade utföringsformen av blandnings- don l0a är detta anslutet till två tillförselkanaler 26, 28 med olika bredd, varvid donets l0a triangulära form ej läng- re är symmetrisk utan kortsidorna har olika längd för an- passning till de olika kanalbredderna.In the embodiment of mixing device 10a shown in Fig. 3, this is connected to two supply channels 26, 28 of different widths, whereby the triangular shape of device 10a is no longer symmetrical but the short sides have different lengths to adapt to the different channel widths.

Det framgår av figurerna 2 och 3 att de raka kana- lerna från inloppssidan A resp. B till utloppssidan C har varierande längd beroende pâ om kanalen börjar vid bland- ningsdonets TO, l0a rätvinkliga hörn eller ligger närmare ett av dess spetsiga hörn. Denna längddifferens kan ge en viss skillnad i tryckfall över blandningsdonets l0, l0a olika partier som i sin tur kan ge upphov till snedbalans i det utströmmande blandade luftflödet vid donets utlopps- sida C.It is apparent from Figures 2 and 3 that the straight channels from the inlet side A and B to the outlet side C have varying lengths depending on whether the channel starts at the right-angled corner of the mixing device TO, l0a or is closer to one of its pointed corners. This difference in length can give rise to a certain difference in pressure drop across the different parts of the mixing device l0, l0a which in turn can give rise to an imbalance in the outgoing mixed air flow at the outlet side C of the device.

Detta problem kan lösas på flera sätt enligt uppfin- ningen. Som framgår av figur 4 vänstra delen är vid den spetsiga änden av blandningsdonet 10 anordnade lister 30, 32, 34 som täcker en del av mynningarna till kanalerna pâ in- loppssidan B. På detta sätt kommer en strypning att ske av den luftmängd som inströmmar vid donets spetsiga ändar, dvs. där kanalerna är kortast, så att en balans åstadkommes i den genom blandarkroppen passerande luftmängden. På detta sätt kommer ungefär samma mängd luft att utströmma jämnt förde- lat över donets utloppsyta C. Som framgår av fig. 4 är lis- ten 34 som är belägen närmast donets l0 spets bredare än de längre bort från spetsen belägna listerna 32 och 30.This problem can be solved in several ways according to the invention. As can be seen from Figure 4, the left part of the pointed end of the mixing device 10 is provided with strips 30, 32, 34 which cover part of the openings to the channels on the inlet side B. In this way, a restriction will occur in the amount of air that flows in at the pointed ends of the device, i.e. where the channels are shortest, so that a balance is achieved in the amount of air passing through the mixer body. In this way, approximately the same amount of air will flow out evenly distributed over the outlet surface C of the device. As can be seen from Figure 4, the strip 34 which is located closest to the tip of the device 10 is wider than the strips 32 and 30 located further away from the tip.

Genom lämpligt arrangemang av listernas bredd och lägen kan en relativt god utjämning av luftbalansen över donet l0 er- hållas.By suitably arranging the width and positions of the strips, a relatively good equalization of the air balance over the device 10 can be obtained.

Strypningen av luftströmmen vid blandardonets l0 spet- siga ändar kan även, såsom visas i fig. 4 högra delen, åstad- kommas med perforerade plåtar med olika hâlprocent. Som fram- går av figuren har plåten 36 ett färre antal häl än plåten 38, som ligger längre in mot donets l0 mitt, dvs. täcker kana- ler med större längd, medan de kanaler som ligger ännu längre in mot donets l0 mitt helt saknar strypanordningar. Med till- lO l5 20 25 30 35 5 hjälp av de perforerade plâtarna 36, 38 kan en mycket nog- grann reglering och utjämning av luftströmmen genom bland- ningsdonet l0 erhållas.The restriction of the air flow at the pointed ends of the mixing device 10 can also, as shown in the right part of Fig. 4, be achieved with perforated plates with different hole percentages. As can be seen from the figure, the plate 36 has a smaller number of holes than the plate 38, which is located further towards the center of the device 10, i.e. covers channels of greater length, while the channels that are located even further towards the center of the device 10 are completely devoid of restriction devices. With the help of the perforated plates 36, 38, a very accurate regulation and equalization of the air flow through the mixing device 10 can be obtained.

Ett annat sätt att utjämna flödena över blandnings- donet är att förse detsamma med tryckutjämningsdon, såsom visas i fig. 5 och.6. Det i fig. 5 visade tryckutjämnings- donet 40 är utfört i samma material som blandningsdonets l0 kropp och med lager av enkelvell staplade på varandra, före- trädesvis med samtliga vell-lager parallella. Tryckutjäm- ningsdonet 40 har därvid raka kanaler som förlöper från en kortsida D av donet 40 parallellt med den andra kortsidan E fram till en sned sida F som ansluter till en av blandnings- donets l0 inloppssidor, så att kanalerna i tryckutjämnings- donet 40 kommunicerar med kanalerna i blandningsdonet l0.Another way to equalize the flows over the mixing device is to provide the same with a pressure equalizing device, as shown in Fig. 5 and 6. The pressure equalizing device 40 shown in Fig. 5 is made of the same material as the body of the mixing device 10 and with layers of single corrugations stacked on top of each other, preferably with all corrugation layers parallel. The pressure equalizing device 40 then has straight channels that run from a short side D of the device 40 parallel to the other short side E up to an inclined side F that connects to one of the inlet sides of the mixing device 10, so that the channels in the pressure equalizing device 40 communicate with the channels in the mixing device 10.

Tryckutjämningsdonets 40 vellhöjd och kantlängdatfavpassas därvid på ett sådant sätt, att tryckfallet vid mediets passage genom de längsta kanalerna i tryckutjämningsdon, resp blandningsdon blir tillnärmelsevis lika stora. De i fig. 5 visade tryckutjämningsdonen kan liksom blandningsdonen fram- ställas från en kvadratisk eller rektangulär kropp, som de- las diagonalt. I fig. 6 visas ett fall, där tryckutjämnings- donens anpassning till tryckfallen i blandningsdonet lett till en oregelbunden form. 4 De i fig. 5 och 6 visade tryckutjämningsdonen 40, 40a åstadkommer ett likformigt fördelat flöde till varje kanal hos blandningsdonen 10, l0a och kan därför användas vid höga krav då en exakt blandning önskas medan utförandet med stryp- ningslister 30, 32, 34 eller -plåtar 36, 38 enligt fig. 4 lämpligen används, då kraven på blandningens jämnhet är måttliga.The wave height and edge length of the pressure equalizer 40 are then adjusted in such a way that the pressure drop when the medium passes through the longest channels in the pressure equalizer or mixing device is approximately the same. The pressure equalizers shown in Fig. 5 can, like the mixing devices, be made from a square or rectangular body that is divided diagonally. Fig. 6 shows a case where the adaptation of the pressure equalizers to the pressure drops in the mixing device has led to an irregular shape. The pressure equalizers 40, 40a shown in Figs. 5 and 6 provide a uniformly distributed flow to each channel of the mixing devices 10, 10a and can therefore be used for high requirements when precise mixing is desired, while the design with restriction strips 30, 32, 34 or plates 36, 38 according to Fig. 4 is suitably used when the requirements for the evenness of the mixture are moderate.

Det framgår av ovanstående att ett blandningsdon åstad- kommits, i vilket tryckfallet över blandningsdonet är väsent- ligt lägre än vid hittills använda blandare. Det kräver även väsentligt mindre volym än de hittills förekommande anord- ningarna. Även när det gäller materialet för donets uppbygg- nad krävs en mindre mängd, varvid dessutom ett tunt material kan användas då de olika lagren effektivt stöder varandra. 3ÛÛ277Û~9 l0 15 20 25 30 35 För att öka blandningsdonets hanterbarhet kan ett skyddande hölje (ej visat) anordnas runt donet och likaså kan detta insättas i kanalsystemet med tillhjälp av hörnprofiler 42, som visas i figurerna.It is clear from the above that a mixing device has been achieved in which the pressure drop across the mixing device is significantly lower than in mixers used to date. It also requires significantly less volume than the devices used to date. Even with regard to the material for the construction of the device, a smaller amount is required, and in addition a thin material can be used since the different layers effectively support each other. 3ÛÛ277Û~9 l0 15 20 25 30 35 To increase the handling of the mixing device, a protective casing (not shown) can be arranged around the device and this can also be inserted into the duct system with the help of corner profiles 42, as shown in the figures.

För temperaturutjämning ger donet en mycket god bland- ningseffekt vid blandning av två medier med olika temperatur.For temperature equalization, the device provides a very good mixing effect when mixing two media with different temperatures.

Blandningsdonet enligt uppfinningen är även mycket användbart vid kemiska kontinuerliga processer där det förekommer bland- nings- och/eller reaktionssteg. Vid blandningssteg ger donet blandning på mycket kort tid. En god blandning innebär korta- re diffusionsväg för de ämnen som skall reagera och följakt- ligen sker hela reaktionen snabbare, vilket ger större pro- duktion per tidsenhet. Vid momentan reaktion i reaktionssteg är blandningshastigheten helt avgörande för produktflödet.The mixing device according to the invention is also very useful in chemical continuous processes where mixing and/or reaction steps occur. In mixing steps, the device provides mixing in a very short time. Good mixing means a shorter diffusion path for the substances that are to react and consequently the entire reaction takes place faster, which gives greater production per unit of time. In the case of instantaneous reaction in reaction steps, the mixing speed is absolutely crucial for the product flow.

Den snabba och intima blandningen som erhålles i blandnings~ donet enligt uppfinningen möjliggör en stor kontinuerlig pro- duktion vid liten reaktionsvolym. Vid snabba reaktioner sker blandning och reaktion samtidigt med åtföljande temperatur- ökning eller -minskning som följd. Den goda blandningen ger en jämn temperatur utan stråk med över- eller undertempera- tur.The rapid and intimate mixing obtained in the mixing device according to the invention enables a large continuous production at a small reaction volume. In rapid reactions, mixing and reaction occur simultaneously with a concomitant increase or decrease in temperature as a result. The good mixing gives an even temperature without streaks of over or under temperature.

Det är klart att uppfinningen ej är begränsad till de visade utföringsformerna utan att dessa kan ändras och varieras inom ramen för de följande patentkraven. Sålunda är det klart att blandningsdonet 10, l0a ej behöver ha den i de olika figurerna visade orienteringen utan att det lika- väl kan anordnas med skikten av enkelvell stående eller i and- ra lägen relativt horisontalplanet. Likaså behöver naturligt- vis vinkeln mellan kanalerna i de intilliggande skikten av enkelvell ej vara rät, utan kommer att variera beroende på formen hos blandningsdonet. Det är naturligtvis även tänk- bart att blandningsdonet är avsett för blandning av fler medier än två. Därvid är det tänkbart att anordna fler in- loppssidor från vilka raka kanaler förlöper pä ett sådant sätt, att de jämnt fördelade mynnar i en gemensam utlopps- Sídä- Vidare kan det bl.a. med hänsyn till tillgängliga tryckfall och förekommande olikheter i flöden, vara för- äÛÛ277lIi-9 deiaktigt att ha en annan Ve11höjd på de kanaier, som iöper i den ena riktningen än på kanaierna iöpande 1 den andra riktningen.It is clear that the invention is not limited to the embodiments shown, but that these can be changed and varied within the scope of the following patent claims. Thus, it is clear that the mixing device 10, 10a does not need to have the orientation shown in the various figures, but that it can also be arranged with the layers of single-well standing or in other positions relative to the horizontal plane. Likewise, the angle between the channels in the adjacent layers of single-well does not naturally need to be right, but will vary depending on the shape of the mixing device. It is of course also conceivable that the mixing device is intended for mixing more media than two. In this case, it is conceivable to arrange more inlet sides from which straight channels extend in such a way that the evenly distributed openings in a common outlet side. Furthermore, it can, among other things, Taking into account available pressure drops and existing differences in flows, it may be advantageous to have a different Ve11 height on the channels running in one direction than on the channels running in the other direction.
