Utstvr for rensinq av vann Water purification equipment
Foreliggende oppfinnelse ang5r utstyr for rensing av vann og sorlig et utstyr for ad elektrolytisk vei & forhindre sopp- og bakterievekst i vannforsyningen. The present invention relates to equipment for purifying water and, in particular, equipment for ad electrolytic treatment and preventing the growth of fungi and bacteria in the water supply.
Bløtgjøringsanlegg for vann som gjør bruk av on ionobytterharpiksWater softening plant that uses on ion exchange resin
er i utstrakt grad benyttet for vanntilførselsinnstallasjoner. lone-bytterharpiksen sørger for å foreta en utbytting av kalsium og magne-siuroioner i vannet med natrium, og regenereres periodisk ved vasking med natriumklorid løsning. I løpet av levetiden til ionebytterhår-piksens bindelag i et slikt bløtgjøringsonlegg, kan det inntreffe tilstander som tillater vekst av sopp og bakterier i harpiksen. is extensively used for water supply installations. the lone exchange resin ensures that calcium and magnesium ions in the water are exchanged with sodium, and is periodically regenerated by washing with sodium chloride solution. During the lifetime of the ion exchange hair pix's bond layer in such a softening installation, conditions may occur that allow the growth of fungi and bacteria in the resin.
Skjønt denne veksten vanligvis er helt uskadelig, kan det føre tilAlthough this growth is usually completely harmless, it can lead to
at vannet blir misfarget og synes å være forurenset, og i ekstreme that the water becomes discolored and appears to be polluted, and in extreme cases
tilfeller kan effektiviteten til ionebytterharpiksen nedsettes.In some cases, the effectiveness of the ion exchange resin may be reduced.
Da vannet skal benyttes som drikkevann, er det av avgjørende betyd-ning at alle tilsatsmidler er fullstendig trygge og ikke giftige. As the water is to be used as drinking water, it is of crucial importance that all additives are completely safe and non-toxic.
Formålet med foreliggende oppfinnelse er derfor .å tilveiebringe et utstyr for å forhindre vekst av sopp oller bakterier i bløtgjørings-anlegg for drikkevann. The purpose of the present invention is therefore to provide a device to prevent the growth of fungi or bacteria in softening plants for drinking water.
For a gi en klarere forståelse av foreliggende oppfinnelse vises til nedenstående detaljerte beskrivelse av et utførelseseksempel og til de ledsagende tegninger, hvori In order to provide a clearer understanding of the present invention, reference is made to the following detailed description of an embodiment and to the accompanying drawings, in which
lig. 1 viser et bløtgjøringsanlégg for vann av ionebyttertypen og utstyrt med en elektrolysecelle for rensing av vannet, og fig. 2 viser en annen utførelse av et tilsvarende bløtgjøringsanlégg. corpse. 1 shows a softening plant for water of the ion exchange type and equipped with an electrolysis cell for purifying the water, and fig. 2 shows another embodiment of a corresponding softening plant.
I fig. 1 hviler bindelaget for ionebytterharpiksen 1 på en perforert plate 2 i en beholder 3. Beholderen 3 har et utløp 4, og et inntak 5 som fører til en elektrolysecelle 6 og et avgreningsrør 7. Symbolene 8, 9 og 10 angir ventiler som fastlegger strømningsverdiene for væsken i rørene 4, 5 henholdsvis 7. Elektrodene 11 til elektrolysecellen 6 er koblet til en vannforsyningkilde (ikke vist) og for-synes med en relativt lav veksel- oller likespenning. F. eks. vil en 6 V spenning fra en nett-transformater være en egnet spennings-kilde. In fig. 1, the binding layer for the ion exchange resin 1 rests on a perforated plate 2 in a container 3. The container 3 has an outlet 4, and an inlet 5 which leads to an electrolysis cell 6 and a branch pipe 7. The symbols 8, 9 and 10 indicate valves which determine the flow values for the liquid in the tubes 4, 5 and 7 respectively. The electrodes 11 of the electrolysis cell 6 are connected to a water supply source (not shown) and are supplied with a relatively low alternating or direct voltage. For example will a 6 V voltage from a mains transformer be a suitable voltage source.
Når bløtgjøringsanlegget er i normal bruk, er ventilen 10 lukket mens ventilene 8 og 9 er åpne og tillater at vann flyter gjennom bindelaget av ionebytterharpiks. Da selv hårdt vann har en svart lav spe-sifikk ledningsevne, vil det bare passere en svært liten elektrolyse-strøm gjennom cellen 6, og elektrolyseproduktene er svsrt små mengder hydrogen og oksygen som blir fullstendig oppløst. When the softener is in normal use, valve 10 is closed while valves 8 and 9 are open allowing water to flow through the bond layer of ion exchange resin. As even hard water has a very low specific conductivity, only a very small electrolysis current will pass through the cell 6, and the electrolysis products are very small amounts of hydrogen and oxygen which are completely dissolved.
Når ionebytterharpiksen er blitt mettet av kalsium og magnesiumioner, kan den regenereres ved & vaskes med natriumkloridløsning. When the ion exchange resin has been saturated with calcium and magnesium ions, it can be regenerated by & washed with sodium chloride solution.
.ye"<fc;l>^i; 9 lukkes herunder, mens ventilen 7 åpnes og natriumklorid-løsning passerer gjennom ionerbyttorharpikabindelagat idet løsningen passerer elektrolysecellen 6. Under denne prosessen foregår det en elektrolyse av saltoppløsningon i cellen slik. at det frembringes natrium hypoklorid og hydrogen etter følgende formel: .ye"<fc;l>^i; 9 is closed below, while the valve 7 is opened and sodium chloride solution passes through the ion exchange torharpicabindelagate as the solution passes the electrolysis cell 6. During this process, an electrolysis of salt solution takes place in the cell so that sodium hypochloride is produced and hydrogen according to the following formula:
Under regeneringsprosessen vil derfor alle spor av soppdannelse eller bakterievekst i ionebytterharpiksen ødelegges av de små mengdene av natrium hypoklorid som foreligger i den utvaskande natriumklorid-løsningen. Etter at regenereringen er fullstendig, lukkes ventilen 7, ventilen 9 åpnes og bindelaget av ionebytterharpiks gjennomstrømmes av vann for å fjerne natriumkloridløsningen hvoretter anlegget på ny er klar til bruk. Eventuelle rester av natrium hypoklorid som fort-satt måtte inneholdes i ionebytterharpiksen er fullstendig uskadelig for forbrukerne. During the regeneration process, all traces of fungus formation or bacterial growth in the ion exchange resin will therefore be destroyed by the small amounts of sodium hypochloride present in the leaching sodium chloride solution. After the regeneration is complete, valve 7 is closed, valve 9 is opened and the binding layer of ion exchange resin is flowed through with water to remove the sodium chloride solution, after which the plant is again ready for use. Any residues of sodium hypochloride that may still be contained in the ion exchange resin are completely harmless to consumers.
Ledningsevnen til vann er så liten at spenningstilførselen til elektrolysecellen kan stå tilkoblet hele tiden. Noen strøm av be-tydning passerer bare i regenereringssyklusen. Med andre ord vil, når spenningstilførselen er permanent tilkoblet, cellen automatisk tre i funksjon for å rense ionebytterharpiksen hver gang denne regenereres. The conductivity of water is so small that the voltage supply to the electrolysis cell can be connected all the time. Some current of significance only passes in the regeneration cycle. In other words, when the voltage supply is permanently connected, the cell will automatically come into operation to clean the ion exchange resin each time it is regenerated.
Foreliggende system kan selvfølgelig også benyttes i forbindelse med andre vaske-elektrolytter. Natriumklorid foretrekkes imidlertid da det både er rimelig i bruk og ikke er giftig. The present system can of course also be used in connection with other washing electrolytes. However, sodium chloride is preferred as it is both inexpensive to use and non-toxic.
Elektrodene 11 må fremstilles av et materiale som hverken an-gripes av elektrolytten eller av elektrolyseproduktene. Grafitt, platina eller andre edle metaller er egnet for denne bruk. The electrodes 11 must be made of a material which is neither attacked by the electrolyte nor by the electrolysis products. Graphite, platinum or other precious metals are suitable for this use.
Mens rensesystemet nå er blitt beskrevet i forbindelse med en kapp^ionebytter, så kan anHLonobyttore behandles på en tilsvarende måte. While the purification system has now been described in connection with a cap^ion exchanger, anHLonobyttare can be treated in a similar way.
Fig. 2 viser en svensk type bløtgjøringsanlégg for vann utstyrt med en elektrolysecelle for rensing av ionebytterharpiksen. Fig. 2 shows a Swedish type of softening plant for water equipped with an electrolysis cell for purifying the ion exchange resin.
Et ionebyttekammer 21 er montert i en ytre beholder 22, som dess-uten inneholder an porøs oller perforert plate 23, som understøtter et lag av aaltkrystaller (Na Cl) 4. Den nedre delen av beholderen 22 utgjør et saltoppløcningareservoar og ned i dette er det montert et ekstraherIngarør 5. Vann flyter gjennom de forskjellige deler av bløtgjøringsanlegget og styres av ventilene 6. An ion exchange chamber 21 is mounted in an outer container 22, which also contains a porous or perforated plate 23, which supports a layer of aluminum crystals (Na Cl) 4. The lower part of the container 22 constitutes a salt dissolution reservoir and down in this there is fitted an extraction pipe 5. Water flows through the different parts of the softening plant and is controlled by the valves 6.
Under normal bruk flyter vannet fra tilførselsledningen ned inntak3røret gjennorn ionebytterharpiksen 8, hvor me tall ionene fjernes, og tilbake opp røret 9 til utløpsrøret 10. Wår ionebytterharpiksen er blitt mettet med metallloner, regenereres den ved å vaskes med During normal use, the water from the supply line flows down the intake 3 pipe back to the ion exchange resin 8, where metal ions are removed, and back up the pipe 9 to the outlet pipe 10. When the ion exchange resin has become saturated with metal ions, it is regenerated by washing with
.natriumkloridløsning. Herunder strømmer det tilførte vann gjennom røret 11 og gjennom an injektor 12 som løfter opp saltoppløsning fra reservoaret og opp i røret 13 slik at saltoppløsningen diriqeres opp røret 14 som inneholder en elektrolysecelle 15 og inn i ionebytter-harpikslaget. Saltoppløsningen passerer gjennom bindelaget og .sodium chloride solution. Below this, the added water flows through the pipe 11 and through an injector 12 which lifts up salt solution from the reservoir and up into the pipe 13 so that the salt solution is directed up the pipe 14 which contains an electrolysis cell 15 and into the ion exchange resin layer. The salt solution passes through the binding layer and
utbytter herved kalsium og magnesiumioner med natrium-ioner, og den anvendte oppløsning flyter opp røret 9 og renner til slutt ut fra ut-løpsrøret 10. thereby exchanges calcium and magnesium ions with sodium ions, and the used solution floats up the pipe 9 and finally flows out from the outlet pipe 10.
Oennc prosessen fortsetter inntil saltløsningsreservoaret er opp-brukt, og hele laget med ionebytterharpiks blir deretter vanket med rent vann fra tilførselskranen for a fjerne natriumklorid. Endelig blir reservoaret med sa1toppiøsning fylt på ny med vann fra inntaket, og derved oppløses ytterligere natriumklorid og bløtgjøringsanlegget er på ny klar til bruk. Under denne sistnevnte påfyllingsprosess blir natriumkloridløsningen elektrolysert i cellen 15 hvorved det dannes en liten mengde natriumhypoklorid som vilødelegge spor av bakterie- eller soppvekst som kan forekomme i ionebytterharpiksen. The process continues until the salt solution reservoir is used up, and the entire layer of ion exchange resin is then washed with clean water from the supply tap to remove sodium chloride. Finally, the reservoir with the sodium chloride solution is refilled with water from the intake, thereby dissolving further sodium chloride and the softening plant is again ready for use. During this latter filling process, the sodium chloride solution is electrolysed in the cell 15 whereby a small amount of sodium hypochloride is formed which destroys traces of bacterial or fungal growth that may occur in the ion exchange resin.
