Description

Uppfinnare: S A B Dahlgren Intim blandning av tvenne vatskor är erforderlig for manga andamal mom industrien, exempelvis for tvattning air en vatska med en annan, for raffinering air olja med syra eller hit och for extraktion av amnen, losta i en vdtska medelst en annan vatska, som är oloslig eller foga loslig i den fOrra. Efter den kemiska eller fysikaliska reaktionen. skola vatskorna, savitt mojligt, snabbt skilj as frdn varandra. Forfarandet utfOres vanligen genom upprepad blandning och separering av vatskorna i flera steg, varvid den ena vatskan le-des i motstrOm mot den andra. Inventor: SAB Dahlgren Intimate mixing of two liquids is required for many andamal mom industry, for example for washing air one liquid with another, for refining air oil with acid or hit and for extraction of the substances, loosening in one liquid by means of another liquid, which is insoluble or join loosely in the former. After the chemical or physical reaction. school the water shoes, as far as possible, quickly separate from each other. The process is usually carried out by repeatedly mixing and separating the liquids in several steps, one liquid being passed in countercurrent to the other.

Flerstegsextraktion utfores ofta i s. k. extraktionstorn, i vilka den lattare vatskan inmatas vid tornets batten och den tyngre vid dess owe dude. Forutsattning for detta forfarande dr, att den vatska, som utgor extraktionsmedel (resp. tvdttmedel vid tvdttningsprocedur), betraffande sin spec. vikt skiljer sig frdn den vdtska, ur vilken bestandsdelar skola bortskaffas genom extraktion eller tvattning. Man utnyttjar salunda tyngdkraften for att driva fram vatskorna genom tor-net, i det att den nedtill inforda, lattare vat skan flyter upp genom den upptill inledda, sjunkande tyngre vatskan. Genom fasta element är tornet invandigt uppdelat i ett antal blandningskam mare och separeringsrum, och genom eft antal bottnar strdvar man att fd sa stor kontaktyta som mojligt mellan de hada vatskorna for att nedbringa den behovliga kontakttiden och Oka utbytet. Multi-step extraction is often performed in so-called extraction towers, in which the lighter liquid is fed at the tower's bat and the heavier at its owe dude. A prerequisite for this procedure is that the liquid, which constitutes an extractant (or detergent in the washing procedure), concerning its spec. weight differs from the liquid from which constituents are to be disposed of by extraction or washing. Gravity is thus used to propel the water shoes through the tower, in that the lighter water introduced at the bottom floats up through the heavier water initiated at the top. Through fixed elements, the tower is internally divided into a number of mixing chambers and separation chambers, and through the number of bottoms it is necessary to obtain as large a contact surface as possible between the hot water tanks to reduce the required contact time and increase the yield.

Viii man genomfora behandlingen mera effektivt och undvika voluminosa extraktionstorn och dylikt, anvander man pumpar for blandningen air de hada vatskorna och centrifugalseparatorer for separeringen. SA genomloper extraktionsmedlet exempelvis vid extraktion i tre steg forst det tredje steget, darefter det andra och slutligen det fiirsta, under det att den vatska, frail vilken man 8nskar extrahera ett i denna lost amne, ledes in i forsta steget och darefter genomloper det andra och sedan det tredje. Mellan varje separeringssteg aterblandas vatskorna i en pump. In order to carry out the treatment more efficiently and to avoid voluminous extraction towers and the like, pumps are used for the mixing of the hot water liquors and centrifugal separators for the separation. For example, in extraction in three steps, SA passes through the extraction first the third step, then the second and finally the first, while the liquid, from which one wishes to extract one in this lost substance, is passed into the first step and then passes through the second and then the third. Between each separation step, the water shoes are remixed in a pump.

Genom tillampning am motstromsprincipen erhaller man en fullstandigare extraktion under anvandande ay en mindre mangd extraktionsmedel och utviriner darjamte extraktet mera koncentrerat. En sadan anlaggning for flerstegsextraktion med flera pnmpar och flera centrifugalseparatorer jamte erforderliga rorledningar och kranar blir dock raft komplicerad och kan giva anledning till lackningar med ty atfoljande forluster och andra oldgenheter. Man liar aril:r konstruerat centrifuger for fullfoljande ay flerstegsbehandlingen inom en och sarnma centrifugrotor. Denna ham da delats upp i sektioner, i vilka blandning, separering och dterblandning av vatskorna successivt dgt rum, varvid vatskornas overforing frail en sektion till en annan skett medelst skalror eller skalskivor, och dam blandningen skett ddrigenom, att de bd.da vatskorna sammanforts i fasta munstycken, frail vilka vdtskeblandningen sprutats ut i en med rotorn roterande vatskering. By applying the countercurrent principle, a more complete extraction is obtained using a smaller amount of extractant and the extract is more concentrated. However, such a system for multi-stage extraction with several pumps and several centrifugal separators as well as the required pipelines and cranes becomes very complicated and can give rise to varnishes with consequent losses and other antiquities. Centrifuges have been designed for completion of the multi-stage treatment within a single centrifuge rotor. This ham was then divided into sections, in which mixing, separation and remixing of the water vials successively took place, the water vesicles being transferred from one section to another by means of shells or shell discs, and the mixing took place by bringing the two water vials together in fixed nozzles, from which the liquid mixture is sprayed into a water ring rotating with the rotor.

However, a mixed mixture is thus obtained which is homogeneous, and it is often obtained as a result that part of the liquid is poorly mixed, while the remainder is too much mixed and consists of a solution-separable emulsion which reduces the capacity of the extraction separator. in subsequent separation steps.

For uppndende av bdsta mojliga extraktionsverkan är det av vikt att beakta, att extraktionen ej sker dgonblickligen, utan extraktionshastigheten ãr omvant proportionell mot radien hos de vatskedroppar, ur vilka ett amne skall extraheras. Om blandningsorganet alstrar dels finare vatskedroppar, dels grovre, bestammes extraktionshastigheten av storleken hos de grovre dropparna. Det är ocksd ay stor vikt, att den ay vatskorna, fran vilken ett amne skall extraheras, utgor den dispersa fasen ay blandningen och extraktionsmedlet den kontinuerliga, ty om det oravanda forhallandet dr forhanden, blir extraktionshastigheten vasentligt ldgre. In order to obtain the best possible extraction effect, it is important to consider that the extraction does not take place immediately, but the extraction rate is inversely proportional to the radius of the liquid droplets from which a substance is to be extracted. If the mixing means produces finer liquid droplets and coarser ones, the extraction rate is determined by the size of the coarser droplets. It is also of great importance that the liquids from which a substance is to be extracted constitute the dispersed phase of the mixture and the extractant the continuous one, because if the unfamiliar ratio is present, the extraction rate becomes substantially slower.

The novelty and pitcher characteristic of this is that the heavier liquid is led into a mixing chamber over a sill on a side radially projecting side cradle from the inner cradle of the separator rotor and that the lighter liquid under overpressure is led into this mixing chamber through fine openings in a rock radially projecting from the center of the rotor towards the sheath of the separator rotor, the lighter liquid in the mixing chamber opposite the heavier liquid being mixed with it and the hot new liquids being formed, which are separated by centrifugal force. .to each other and led to different sewers.

Uppfinningen avser aven separator for utforande av detta salt, vilken separator har skilda tillopp for en lattare och en tyngre vatska och skilda avlopp for en lattare och en tyngre i separatorn bildad vatskekomponent och en rotor, som ar forsedd med skiljevaggar for att leda vatskorna och vatskekomponenterna genom rotorn samt med separeringsrum for att skilja de hada vatskekomponenterna fran varandra. Det framst nya och kannetecknande fair denna separator utgOres av i en eller flera av skiljevaggarna anordnade fina oppningar for att finfordela den lattare vatskan i den tyngre och av ett tillopp fOr den lattare vfitskan och ett avlopp for den lattare komponenten, anordnade pa sadant satt i rotorn, att ett for insprutning av den lattare vatskan i den tyngre erforderligt tryck astadkommes pa den lattare vatskan. The invention also relates to a separator for making this salt, which separator has different inlets for a lighter and a heavier liquid and different drains for a lighter and a heavier liquid component formed in the separator and a rotor which is provided with partitions to guide the liquids and the liquid components. through the rotor and with separation chambers to separate the hot liquid components from each other. The foremost new and jug-like fair this separator consists of fine openings arranged in one or more of the partitions to distribute the lighter liquid in the heavier and of an inlet for the lighter liquid and a drain for the lighter component, arranged in such a way in the rotor , that an injection of the lighter liquid into the heavier required pressure is effected on the lighter liquid.

Genom lampligt val av oppningar och tryckskillnader, vilka senare kunna regleras under centrifugens gang, kan storleken av de vaiskedroppar, som bildas vid utstromningen genom de fina oppningarna, godtyckligt regleras, sit att man uppnar de basta betingelserna for ex-traktionen utan att riskera uppkomsten av svar- eller oseparerbara emulsioner. By suitable choice of openings and pressure differences, which can later be regulated during the centrifuge, the size of the liquid droplets formed during the outflow through the fine openings can be arbitrarily regulated, provided that the best conditions for extraction are achieved without risking the formation of responsive or inseparable emulsions.

The bottoms 8 and 9 only at the hire edge up strut-shaped plates 23, which form mixing ring chambers 24, receive the bath watercress and partially enclose the openings 16, 17. The lighter water flows out after the last separation into a receiving vessel 18 and the heavier water flows out into a receiving vessel located under the rotor 19. The lighter liquid is led to the mixing device through a channel and a space 20, and the heavier liquid is led in through a channel 21. After separation, the lighter liquid is passed through one or more channels 22 between the cradles 4 and 5 out to the openings 17.

Enligt fig. 3 har kammaren 24 en mera langstraekt form samt ar latt bOjd och svangd -snett bakat. Mellan de fina oppningarna 16 och avloppet 26 far den tyngre vatskan bildas salunda ett separeringsrum, dar de mindre, av den tyngre vatskan medfOrda dropparna av den lattare vatskan vandra inat och darigenom utsepareras, innan den tyngre vatskan. nar Oppningen 26. Fig. 4 visar en vertikal sektion av denna utfiiringsform genom oppning-arna 16. According to Fig. 3, the chamber 24 has a more elongated shape and is slightly bent and curved. Between the fine openings 16 and the drain 26, the heavier liquid is thus formed a separation space, where the smaller droplets of the lighter liquid carried by the heavier liquid migrate inwards and thereby are separated out, before the heavier liquid. The opening 26. Fig. 4 shows a vertical section of this embodiment through the openings 16.

Den beskrivna anordningen fungerar vid anvandning fOr extraktion pa Viljande satt. Det f8rutsattes, att den lattare vatskan innehailer det amne, som skall extraheras. Denna vatska fares genom det centrala roret 12 till kanalen 20 i rotorns botten, och den tyngre vatskan, som alltsa i detta fall utgor extraktions- eller losningsmedlet, ledes genom raret 13 och kanalerna 21 in i rotorns Owe del. Genom lampligt val av bra ddavloppets 15 och oppningarnas 16 diameter samt genom lamp-hg avpassning av den per tidsenhet inmatade vatskemangden, far man gransnivan mellan den lattare och den tyngre vatskan installd i ett visst lampligt radiellt lage i inledningskanalen 20, lampligen nagot utanf Or Oppningar'na 16. Den hare fria vatskenivan far den lattare vatskan kommer darvid att bli farlagd nara rotationsaxehi. Om for braddavloppet 14 valles en st8rre diameter an f6r den fria vatskenivan i inledningskanalen 20, kommer den —3 inre, fria vatskenivan i separeringsrummet A att automatiskt stalla in sig pa ett storre avstand fran rotationsaxeln an den fria nivan i kanalen 20, men pa ett mindre avstand an braddavloppet 14. Gransnivan i varje separetingsrum kommer darvid att ligga pa en suecessivt mindre radie an gransnivan i kanalen 20. The described device works when used for Extraction in the Intentional Way. It was assumed that the lighter liquid contained the substance to be extracted. This liquid is passed through the central tube 12 to the channel 20 in the bottom of the rotor, and the heavier liquid, which in this case constitutes the extraction or discharging agent, is led through the tube 13 and the channels 21 into the Owe part of the rotor. By light selection of the diameter of the good drain 15 and the openings 16 and by light adjustment of the water basket fed in per unit time, the spruce level between the lighter and the heavier water is set in a certain light radial layer in the opening channel 20, preferably slightly outside Or openings. 'na 16. The hare free water level from the lighter water will then be colored near the axis of rotation. If a larger diameter is chosen for the brad drain 14 for the free water level in the inlet channel 20, the inner, free water level in the separation space A will automatically adjust to a greater distance from the axis of rotation than the free level in the channel 20, but on a smaller distance than the spruce drain 14. The spruce level in each separation room will then be at a successively smaller radius than the spruce level in the channel 20.

Pa undersidan av den vagg, som an fOrsedd med oppningarna 16, kommer man dd att ha den lattare vatskan och pa oversidan den tyngre vatskan. Det genom rotationen aistra- depa den lattare vatskan blir vid ra- dien for oppningarna hogre an det pa samma sat alstrade trycket pa den tyngre vatskan ovanfor samma vagg. Den lattare vatskan kommer dad& att strOmma genom oppningarna och sprutas in i den tyngre vatskan i form av en mangd fina, fran varandra skilda droppar av i det narmaste samma storlek. On the underside of the cradle, which is provided with the openings 16, you will then have the lighter liquid and on the upper side the heavier liquid. The lighter liquid produced by the rotation at the radius of the openings becomes higher than the pressure generated in the same way on the heavier liquid above the same rock. The lighter liquid will then flow through the openings and be injected into the heavier liquid in the form of a multitude of fine, distinct drops of almost the same size.

Som exempel pa hur pass stora tryckskillnader, som kunna uppnhs ph detta sat, kan angivas, att om skillnaden i spec. vikt mellan vatskorna ar 0,2, centrifugens varvtal 4000 vary/min, gransnivan mellan den lattare och tyngre vatskan forlagd till en radie av 15 cm och oppningarna 16 forlagda till en radie av 14 cm, erhalles en tryckskillnad vid oppningarna 16 pa omse sidor om vaggen 3 av c:a 0,65 kp/cm2, vilket vid lattflytande vatskor ger en genomstriimningshastighet av c:a 11 m/sek. As an example of how large pressure differences can be achieved in this way, it can be stated that if the difference in spec. weight between the liquids is 0.2, the speed of the centrifuge 4000 varies / min, the spruce level between the lighter and heavier liquid is placed to a radius of 15 cm and the openings 16 are placed to a radius of 14 cm, a pressure difference is obtained at the openings 16 on each side of cradle 3 of approx. 0.65 kp / cm2, which in the case of low-flowing water shoes gives a flow rate of approx. 11 m / sec.

Den tyngre vatskan, som utgiir extraktionseller losningsmedlet, ledes genom roret 13 till kanalen 21, som leder vatskan vidare till yttersta delen av separeringsrummet B. Detta rum begransas i sin yttre del nedtill av bottnen 8, som tillsammans med vaggen 23 tyingar den tyngre vatskan att passers blandningskammaren 24 mitt for oppningarna 17. Genom dessa fina 8ppningar sprutas den lattare vatskan in i form av fina droppar, som tillsammans bilda en rida, strackande sig fran vaggen 5 upp till vaggen 23, Mellan dropparna i denna rida passerar den tyngre vatskan utat. Om det, sasom visat i fig. 1, finnes tvenne rader hal 17, bildas aven frail den yttre raden en rida av fina droppar, och den tyngre vatskan 'piste saledes pa sin vag utat passera tvenne sadana ridaer. Darefter avgar den genom oppningen 26 till separeringsrummet A. The heavier liquid, which releases the extraction or solvent, is led through the tube 13 to the channel 21, which leads the liquid further to the outermost part of the separation space B. This space is delimited in its outer part at the bottom by the bottom 8, which together with the cradle 23 forces the heavier liquid to the mixing chamber 24 is passed in the middle of the openings 17. Through these fine openings the lighter liquid is injected in the form of fine drops, which together form a ride, extending from the cradle 5 up to the cradle 23. Between the drops in this ride the heavier liquid passes outwards. If, as shown in Fig. 1, there are two rows of hall 17, a ridge of fine droplets is also formed from the outer row, and the heavier water 'piste thus on its way out passes two such ridges. It then exits through the opening 26 to the separation space A.

De fran halen 17 kommande sma dropparna rora sig forst rakt uppat men avbojas efter hand ink, eftersom deras inaehall ar lattare an den omgivande tyngre vatskan. By. rora de sig inat forst sedan de traffat den snedstallda vaggen 23. I vilket fall som heist samlas de efterhand vid gransnivan mellan den tyngre och lattare vatskan, dar huvudparten av vatskorna separeras. Svarseparerbarn fragment av den tyngre vatskan folja emellertid med den lattare vatskan mat till platsatsen 11, dar en slutgiltig och savitt moj ligt fullstandig separering sker pa vid centrifuger med sadana insatser val kant satt. The droplets coming from the tail 17 first move straight up but are gradually deflected, as their inhalation is lighter than the surrounding heavier liquid. Village. they move inwards only after they have hit the sloping cradle 23. In any case, they gradually gather at the spruce level between the heavier and lighter water, where most of the water shoes are separated. Response-separating fragments of the heavier liquid, however, follow with the lighter liquid food to the seat set 11, where a final and as far as possible complete separation takes place on centrifuges with such inserts selected.

Nar den tyngre vatskan drives genom riclan eller ridaerna av fina droppar av den kit-tare vat skan, komma de hada vatskorna i en synnerligen intim kontakt med varandra, och darmed ar en for extraktion vasentlig betingelse forhanden. Den tyngre vatskan blir anrikad pa. det amne, som skall extraheras. Vid dubbel rida blir extraktionen langre driven. When the heavier liquid is driven through the riclan or the ridges by fine drops of the putty water, the hot liquors come into a very intimate contact with each other, and thus a condition essential for extraction is present. The heavier liquid is enriched. the substance to be extracted. In double riding, the extraction is driven longer.

I separeringsrummets A blandningskammare 24 upprepas den nyss beskrivna intima blandningen mellan tyngre och lattare vatskor, och den tyngre vatskan blir darigenom ytterligare amikad pa det amne, som shall extraheras. I detta tillstand gar den tyngre vatskan vidare till yttre delen av rummet 20 och avledes darifran medelst kanalen 25 till braddavloppet 15. In the mixing chamber 24 of the separation chamber A, the intimate mixture just described between heavier and lighter fluids is repeated, and the heavier fluid is thereby further amicated on the substance to be extracted. In this state, the heavier liquid continues to the outer part of the room 20 and is diverted therefrom by means of the channel 25 to the brad drain 15.

Fra'n sepaxeringsrummets A inre del ledes den lattare vatskan vidare genom kanalen 22 till oppningarna 17 och sprutas genom dessa pa nytt in i tyngre vatska i separeringsrummets B blandningskammare 24. Darefter gar den lattare vatskan jamte fragment av den tyngre vatskan in i platsatsen 11 i rummet B, dar den savitt molligt fullstandigt befrias fran tyngre vatska. Fran rummets B inre del avgar den lattare vatskan Over braddavloppet 14 fran rotorn. From the inner part of the separating chamber A, the lighter liquid is passed on through the channel 22 to the openings 17 and is sprayed through them again into heavier liquid in the mixing chamber 24 of the separating chamber B. Then the lighter liquid and fragments of the heavier liquid enter the location 11 in room B, where the savit chubby is completely freed from heavier liquid. From the inner part of room B, the lighter liquid Over the brad drain 14 emits from the rotor.

Den lattare vatskans vag genom rotorn markeras i fig. 1 med heldragna pilar och den tyngre yatskans huyudyag angives med streckade pilar. The vagina of the lighter water through the rotor is marked in Fig. 1 with solid arrows and the huyudyag of the heavier yat is indicated by dashed arrows.

Genom den upprepade blandningen med darpa foljande separering av vatskorna sker en successiv utlosning av det anme, som skall extraheras ur den lattare vatskan, och genom att leda den tyngre vatskan, losnings- eller extraktionsmedlet, i motstrom mot den lattare, uppn'as en langre driven extraktion och ett mera koncentrerat extrakt, On som eljest skulle vara mojligt. I anordningen enligt fig. 1 och 2 astadkommes blandningen enbart genom med rotorn roterande ()eh orOrligt fOrbundna organ, varigenom konstruktionen blir mycket enkel. Through the repeated mixing with darpa following separation of the liquids, a gradual release of the anem to be extracted from the lighter liquid takes place, and by passing the heavier liquid, the release or extraction agent, in opposite current to the lighter one, a longer driven extraction and a more concentrated extract, On which would otherwise be possible. In the device according to Figs. 1 and 2, the mixture is effected only by means rotating () or properly connected to the rotor, whereby the construction becomes very simple.

Den i fig. 5 visade utforingsformen Or en modifikation av den i fig. 1 visade., Den har ett joke roterbart, i rotorns centrala del inskjutande organ 51, som bar upp eller inne- sluter de for vatskornas tillforande, borlledning och ovrig transport erforderliga delarna. The embodiment Or shown in Fig. 5 is a modification of the embodiment shown in Fig. 1. It has a joke rotatable member 51 projecting in the central part of the rotor, which carried up or enclosed the necessary for the supply, drill line and other transport of the water pipes. the parts.

Organet 51 har ocksa for transporten erfor- derliga kanaler. Den tyngre vatskan ledes in genom en central kanal 52 och den lattare ge- nom ett munstycke 53, anslutet till en annan kanal i delen 51. Den tyngre vatskan ledes bort medelst ett skalror 54 eller en skalskiva och den lattare medelst ett skalror 55 (som ocksa kan ersattas med en skalskiva). Fran munstycket 53 str8mmar den lattare vatskan in 1 en tryckkammare 56. Rotorn Or i langd- 4— — riktningen delad upp i ett antal separeringsrum A,B och C, forsedda med insatsplatar 57. Forutom tryckkammaren 56, sum mottager vatskan frail munstycket 53, finnes en likadan tryckkammare for vartdera av de ovriga stegen. Fran. separeringsrummets C innanfor platarna 57 belagna del ledes den lattare vatskan medelst ett skalror 58 till nasta tryckkammare 56. Pa. samma satt ledes den Mitare vatskan fran separeringsrummet B till paftiljande tryckkammare 56 medelst ett skalror 59. Sasom framgar av figuren pumpas pa detta salt vatskan Iran en langre ut belagen niva i separeringsrummet till en langre in belagen niva i tryckkammaren. Man erhaller pa. sä satt den tryckskillnad, sum behovs for att driva den lattare vatskan in i den tyngre utan att farlagga de fria vatskenivaerna i de rum, dar vatskorna bortforas av skalroren 54 och 55, alltfor langt ut frhn rotationsaxeln. P5. sh satt undvikes alltfor slur kraftforbrukning vid drift av rotorn, samtidigt sum utrymmet I denna kan val utnyttjas for separering. The body 51 also has channels required for transport. The heavier liquid is led in through a central channel 52 and the lighter one through a nozzle 53, connected to another channel in the part 51. The heavier liquid is led away by means of a shells 54 or a shell disc and the lighter one by means of a shells 55 (which can also be replaced with a shell disc). From the nozzle 53 the lighter liquid flows into a pressure chamber 56. The rotor Or in the longitudinal direction is divided into a number of separation chambers A, B and C, provided with insert plates 57. In addition to the pressure chamber 56, which receives the liquid from the nozzle 53, there is a similar pressure chamber for each of the other steps. Fran. the lighter part of the separating chamber C inside the plates 57 is led by means of a scalar 58 to the next pressure chamber 56. Pa. In the same way, the Miter liquid is led from the separation chamber B to the pausing chamber 56 by means of a scalar 59. As can be seen from the figure, on this salt liquid Iran is pumped a longer coated level in the separation chamber to a longer coated level in the pressure chamber. Man erhaller pa. then the pressure difference needed to drive the lighter liquid into the heavier one without discoloring the free water levels in the rooms where the liquids are removed by the scales 54 and 55 was too far out from the axis of rotation. P5. sh sat avoids too sluggish power consumption during operation of the rotor, at the same time sum the space In this, selection can be used for separation.

Fran tryckkammaren 56 strommar den lattare vatskan genom fina oppningar 61, forlagda i fran rotorns centrum mot dess mantel radiellt utskjutande vaggar 56a, ut i blandningskamrar 60 genom vilka den tyngre vatskan strommar till avlopp 61a, liggan.de mellan vaggarna 56a och fran rotorns centrum radiellt inskjutande vaggar 60a. De bada vatskorna blandas darvid intimt pa samma satt sum är beskrivet i saraband med fig. 1. Den tyngre vatskan passerar genom de av den lattare vatskan bildade ridherna av fina vatskedroppar till nasta separeringsrum, sasom de streckade pilarna angiva. Efter varje blandning sker separering pa Mut beskrivet salt. Den lattare vatskans vag markeras med heldragna pilar. From the pressure chamber 56 the lighter liquid flows through fine openings 61, located in from the center of the rotor towards its mantle radially projecting rocks 56a, out into mixing chambers 60 through which the heavier liquid flows to drain 61a, lying between the rocks 56a and from the center of the rotor radially inset rocks 60a. The two liquids are then mixed intimately in the same way as is described in connection with Fig. 1. The heavier liquid passes through the ridges formed by the lighter liquid of fine water droplets to the nearest separation space, as indicated by the dashed arrows. After each mixing, separation takes place on Mut described salt. The vagueness of the lighter water is marked with solid arrows.
