Description
25 30 534 496 typ av vattenkranar, samt den ytterligare utrustning som krävs, ganska dyr och ännu inte för varje hushåll. 25 30 534 496 type of water taps, as well as the additional equipment required, quite expensive and not yet for every household.
En ytterligare nackdel med de ovan nämnda systemen är att de kräver en bra kranvattenkvalitet då vattnet annars inte kommer att smaka gott även om det är kolsyrat. Detta begränsar användningen av dessa system till länder /regioner med rent vatten av god kvalitet.An additional disadvantage of the above-mentioned systems is that they require a good tap water quality as the water will otherwise not taste good even if it is carbonated. This limits the use of these systems to countries / regions with good quality clean water.
KORT BESKRIVNING AV UPPFINNINGEN Ändamålet med föreliggande uppfinning är att avhjälpa nackdelarna med den kända tekniken och att tillhandahålla en metod för framställning av rent, kolsyrat vatten lokalt.BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to remedy the disadvantages of the prior art and to provide a method for producing clean, carbonated water locally.
Enligt en huvudaspekt av uppfinningen kännetecknas den av en metod att behandla kranvatten, innefattande organ för att exponera rinnande kranvatten inkluderande UV-generande organ istånd att exponera vattnet med UV-ljus för att skapa radikaler, vilka radikaler behandlar vattnet, kännetecknad av införandet av koldioxid uppströms nämnda UV-genererande organ, vilken koldioxid skapar en spridning av nämnda UV- ljus för att förbättra behandlingen samt att kolsyresätta nämnda vatten for drickändamål.According to a main aspect of the invention, it is characterized by a method of treating tap water, comprising means for exposing running tap water including UV generating means capable of exposing the water to UV light to create radicals, which radicals treat the water, characterized by the introduction of carbon dioxide upstream said UV-generating means, which carbon dioxide creates a scattering of said UV light to improve the treatment and to carbonate said water for drinking purposes.
Enligt en annan aspekt av uppfinningen gynnar nämnda koldioxid prodduktionen av radikaleri det att syre i koldioxiden konverteras till ozon genom nämnda UV-ljus, vilket UV-ljus samtidigt bryter ner ozonet till radikaler. ' Fördelarna med föreliggande uppfinning ärflera. Införandet av koldioxid i vattenkranen reducerar miljö- och den ekonomiska påverkan som annars är fallet med buteljerat kolsyrat vatten. A Den stora fördelen med föreliggande uppfinning är dock att vattnet som flödar från vattenkranen behandlas för att förbättra vattenkvaliteten mycket, dvs. att verkligen göra det drickbart direkt från kranen och även kolsyrat. 10 15 20 25 30 _ Fig. 2 534 496 Den ytterligare fördelen är att den tillförda koldioxiden även, förutom aspekten med att kolsyresätta, även verkar som en förbättrare av behandlingsprocessen i det att den gynnar spridningen av ljus, vilket därmed förbättrar effektiviteten hos behandlingen och som även skapar turbulens i vattnet, vilket ytterligare gynnar den förbättrade effektiviteten. Dessutom ger närvaron av koldioxid ytterligare syre, vilket kan konverteras till ozon av UV-ljuset, vilket ozon bryts ner till radikaler av UV-ljuset.According to another aspect of the invention, said carbon dioxide promotes the production of radicals that oxygen in the carbon dioxide is converted to ozone by said UV light, which UV light simultaneously breaks down the ozone into radicals. The advantages of the present invention are several. The introduction of carbon dioxide in the water tap reduces the environmental and economic impact that is otherwise the case with bottled carbonated water. A The great advantage of the present invention is, however, that the water that flows from the water tap is treated to improve the water quality a lot, ie. to really make it drinkable directly from the tap and also carbonated. Fig. 2 534 496 The further advantage is that the added carbon dioxide also, in addition to the aspect of carbonation, also acts as an enhancer of the treatment process in that it promotes the scattering of light, which thereby improves the efficiency of the treatment and which also creates turbulence in the water, which further benefits the improved efficiency. In addition, the presence of carbon dioxide provides additional oxygen, which can be converted to ozone by the UV light, which ozone is broken down into radicals by the UV light.
Därigenom förbättras behandlingsprocessen ännu mer.This further improves the treatment process.
Således ger föreliggande uppfinning ett renat dricksvatten som kan kolsyras, varvid introduktionen av koldioxid har flera funktioner.Thus, the present invention provides a purified drinking water which can be carbonated, the introduction of carbon dioxide having its functions.
Dessa och andra aspekter på och fördelar med föreliggande uppfinning kommer att framgå av den följande detaljerade beskrivningen och från de bifogade ritningsfigurerna.These and other aspects and advantages of the present invention will become apparent from the following detailed description and from the accompanying drawings.
KORT BESKRIVNING AV RITNINGSFIGURERNA I den följande detaljerade beskrivningen av uppfinningen kommer hänvisning att göras till de bifogade ritningsfigurerna, där F ig. 1 uppfinning, och schematiskt visar ett kranvattenarrangemang som innefattar föreliggande schematiskt visar en variant på kranvattenarrangemanget enligt Fig. 1.BRIEF DESCRIPTION OF THE DRAWINGS In the following detailed description of the invention, reference will be made to the accompanying drawings, in which FIGS. 1 invention, and schematically shows a tap water arrangement comprising the present schematically shows a variant of the tap water arrangement according to Fig. 1.
DETALJERAD BESKRIVNING AV UPPFINNINGEN Anordningen enligt föreliggande uppfinning innefattar en vattenbehandlingsenhet. I utföringsformen som visas l figurerna är en vattenkran 10 monterad på ett fast underlag såsom en diskbänk 12 eller liknande. Kranen är ansluten till ett rörsystem 14 för kranvatten, vilket ger kranvatten till kranen. Kranen är vidare anordnad med ett vred 16 för hantering av en ventil inuti kranen, för att kontrollera vattenflödet genom kranen. Dessa komponenter är välkända för alla. 10 15 20 25 so, 534 496 Enligt föreliggande uppfinning innefattar denna en vattenbehandlingsenhet 20 anordnad i kranvattenflödet, iden visade utföringsformen före ventilen sett i flödesriktningen, även om vatten behandlingsenheten kan placeras efter ventilen, såsom kommer att framgå av den följande beskrivningen.DETAILED DESCRIPTION OF THE INVENTION The device of the present invention comprises a water treatment unit. In the embodiment shown in the figures, a water tap 10 is mounted on a solid base such as a sink 12 or the like. The tap is connected to a pipe system 14 for tap water, which provides tap water to the tap. The tap is further provided with a knob 16 for handling a valve inside the tap, to control the water flow through the tap. These components are well known to all. According to the present invention, it comprises a water treatment unit 20 arranged in the tap water well, the embodiment shown before the valve seen in the flow direction, although the water treatment unit can be placed after the valve, as will appear from the following description.
Behandlingsenheten innefattar ett antal UV-genererande organ 22 istànd att generera UV i området mellan 180 - 400 nm. I synnerhet är de UV-genererande organen istànd att generera UV-ljus med 183,7 och 254 nm. våglängden 183,7 nm i synnerhet konverterar syret i mediet till ozonmolekyler. Ozonmolekylerna som formas bryts samtidigt ner av strålningen inom det ovan nämnda området, i synnerhet vid en våglängd på 254 nm, vilket gör att det skapade ozonet bryts ner för att forma atomärt syre.The treatment unit comprises a number of UV generating means 22 capable of generating UV in the range between 180 - 400 nm. In particular, the UV generating means are capable of generating UV light at 183.7 and 254 nm. the wavelength 183.7 nm in particular converts the oxygen in the medium to ozone molecules. The ozone molecules that are formed are simultaneously decomposed by the radiation within the above-mentioned range, in particular at a wavelength of 254 nm, which means that the created ozone is decomposed to form atomic oxygen.
För att ha en kompakt behandlingsenheti anslutning till en vattenkran, innefattar de UV-genererande organen små UV-genererande ljusdioder (LED's) istànd att generera UV-ljus i det ovans nämnda området och i synnerhet 183,7 nm och 254 nm.In order to have a compact treatment unit connected to a water tap, the UV-generating means comprise small UV-generating light emitting diodes (LEDs) capable of generating UV light in the above-mentioned range and in particular 183.7 nm and 254 nm.
LED'erna kan vara anordnade i ett rörformat hölje 24 och anordnade runt Omkretsen så att hela volymen hos höljet bestrålas.The LEDs may be arranged in a tubular housing 24 and arranged around the perimeter so that the entire volume of the housing is irradiated.
Vidare, för att öka mängden radikaler som genereras l vätskan är katalysatorer 26 anordnade i höljet så att de exponeras för UV-ljus. Ett antal material som kan användas som katalysatorer innefattar metaller och/eller metalloxider, såsom ädelmetaller, aluminiumoxid, titanoxid, kiseloxid och blandningar av dessa.Furthermore, in order to increase the amount of radicals generated in the liquid, catalysts 26 are arranged in the casing so that they are exposed to UV light. A number of materials that can be used as catalysts include metals and / or metal oxides, such as noble metals, alumina, titanium oxide, silica, and mixtures thereof.
Det katalytiska materialet kan täcka innerytorna hos höljet men kan även anordnas pà en vattengenomsläpplig struktur såsom ett nät, icke-vävda fibrer och liknande och är placerad antingen tvärs flödesriktningen eller i flödesriktningen. Exempelvis kan materialet hos den genomsläppliga strukturen vara kvartsglas, vilket ökar möjligheterna att sprida UV-ljuset inuti höljet.The catalytic material can cover the inner surfaces of the casing but can also be arranged on a water-permeable structure such as a net, non-woven fibers and the like and is placed either across the flow direction or in the fate direction. For example, the material of the permeable structure may be quartz glass, which increases the possibilities of scattering the UV light inside the casing.
Enligt föreliggande uppfinning är UV-lamporna anslutna via elektriska ledningar 28 till en kraftkälla. Enligt ett exempel som visas innefattar kraftkällan en elektrisk generator 30 anordnad i en höljesdel hos vattenkranen. Till axeln hos den elektriska 10 15 20 25 30 534 496 generatorn är en impeller 30 ansluten. impellern kan antingen _vara anbringad direkt till axeln eller via en lämplig transmission. impellern är placerad i ett impellerhölje 34 i vattenkranen, där impellerhuset är anordnat i kranens vattenflöde. En lämplig tätning är anordnad mellan impellerhuset och generatorhuset.According to the present invention, the UV lamps are connected via electrical wires 28 to a power source. According to an example shown, the power source comprises an electric generator 30 arranged in a housing part of the water tap. An impeller 30 is connected to the shaft of the electric generator. the impeller can either be attached directly to the shaft or via a suitable transmission. the impeller is placed in an impeller housing 34 in the water tap, where the impeller housing is arranged in the water fl of the tap. A suitable seal is arranged between the impeller housing and the generator housing.
En annan utföringsform av föreliggande uppfinning kan innefatta ett batteripack (ej visat) istället eller i tillägg till generatorn. Om kraft från batterierna används för att driva lamporna är en brytare anordnad på vattenkranen, vilken företrädesvis aktiveras när vattnet vrids på så att kraften från batterierna till lamporna slås på när vattnet vrids på. Inom föreliggande uppfinning är det naturligtvis möjligt att ansluta lamporna till byggnadens elnät företrädesvis via en lämplig transformator.Another embodiment of the present invention may include a battery pack (not shown) instead or in addition to the generator. If power from the batteries is used to drive the lamps, a switch is arranged on the water tap, which is preferably activated when the water is turned on so that the power from the batteries to the lamps is turned on when the water is turned on. Within the present invention, it is of course possible to connect the lamps to the building's electrical network, preferably via a suitable transformer.
Vidare är vattenkranen enligt föreliggande uppfinning anordnad med en anslutning 40, till vilken en patron med koldioxid 42 kan anbringas. I detta avseende är anslutningen anordnad att passa ihop med lämplig storlek och typ av patron.Furthermore, the water tap according to the present invention is provided with a connection 40, to which a cartridge with carbon dioxide 42 can be mounted. In this respect, the connection is arranged to fit with the appropriate size and type of cartridge.
Anslutningen är företrädesvis anordnad med någon typ av ventil 44 för att sätta på och stänga av tillförseln av koldioxid.The connection is preferably provided with some type of valve 44 for switching on and off the supply of carbon dioxide.
När kranvredet 16 vrids på börjar vattnet att flöda genom impellerhuset 34, varvid impellern 32 börjar rotera. Detta i sin tur gör att generatorn 30 roterar och levererar ström till UV-lamporna 22, varvid de tänds och behandlingsprocessen beskriven ovan startas. Således, så snart vatten börjar flöda genom vattenkranen, behandlas vattnet som flödar genom denna. Vidare är effekten som avges från generatorn proportionell mot flödeshastigheten, i det att ett lågt flöde genererar en låg rotationshastighet hos generatorn, medan ett högt flöde genererar en hög rotationshastighet, vilket ger mer effekt till lamporna. Detta är en fördel med utföringsformen då ett högre flöde kräver mer uteffekt från lamporna.When the tap knob 16 is turned on, the water begins to flow through the impeller housing 34, whereby the impeller 32 begins to rotate. This in turn causes the generator 30 to rotate and supply power to the UV lamps 22, whereby they are turned on and the treatment process described above is started. Thus, as soon as water begins to fl through the water tap, the water flowing through it is treated. Furthermore, the power emitted from the generator is proportional to the speed of fate, in that a low fate generates a low rotational speed of the generator, while a high flow generates a high rotational speed, which gives more power to the lamps. This is an advantage of the embodiment as a higher fl fate requires more output power from the lamps.
Enligt uppfinningen, samtidigt som ventilen 42 som kontrollerar tillförseln av koldioxid öppnas, tillförs koldioxid till det rinnande vattnet. Som synes från ritningsfiguren är tillförseln av koldioxid anordnad uppströms om lamporna. 10 15 534 496 När bubbloma av koldioxid passerar in iljuset från UV-lampoma, skapar de en spridningseffekt hos ljuset och stràlbanan genom vattnet kommer att bli mer zigzag- liknande. Detta ökar vägen i vatten för att nà alla områden i vattenvolymen som den passerar genom och den effektiva ljusabsorptionen kommer att vara hög. införandet av koldioxidbubblor skapar även turbulens i vätskan, vilket även gynnar spridningen av ljus.According to the invention, at the same time as the valve 42 which controls the supply of carbon dioxide is opened, carbon dioxide is supplied to the running water. As can be seen from the drawing figure, the supply of carbon dioxide is arranged upstream of the lamps. 10 15 534 496 When the carbon dioxide bubbles pass into the light from the UV lamps, they create a scattering effect of the light and the beam path through the water will become more zigzag-like. This increases the path in water to reach all areas of the water volume through which it passes and the effective light absorption will be high. the introduction of carbon dioxide bubbles also creates turbulence in the liquid, which also favors the scattering of light.
Förutom den ljusspridande effekten som koldioxidbubblorna skapar kommer UV- strålningen på dessa bubblor även att skapa en generering av ozon i det att UV-ljuset till viss del kommer att konvertera syret i vattnet till ozon, vilket ozon sedan bryts ner till radikaler. Således erhålles en mycket effektiv reningsverkan genom kombinationen att introducera koldioxid och behandlingen med UV-strålning.In addition to the light scattering effect that the carbon dioxide bubbles create, the UV radiation on these bubbles will also create a generation of ozone in that the UV light will to some extent convert the oxygen in the water to ozone, which ozone is then broken down into radicals. Thus, a very effective cleansing effect is obtained by the combination of introducing carbon dioxide and the treatment with UV radiation.
Det skall förstås att utföringsformen som beskrivits ovan och som visas i figurerna endast skall betraktas som icke-begränsande exempel och att den kan modifieras på många sätt inom patentkravens skyddsomfàng.It is to be understood that the embodiment described above and shown in the drawings are to be considered as non-limiting examples only and that it may be modified in many ways within the scope of the claims.
