(74) Fuldmægtig “ (54) Fremgangsmåde til fremstilling af stærkt oxiderende/desinficerende radikaler ved in-situ behandling af ozon med ultralyd og apparat til udøvelse af fremgangsmåden.(74) Plenipotentiary (54) Process for the preparation of highly oxidizing / disinfecting radicals by in-situ treatment of ozone with ultrasound and apparatus for carrying out the process.

Den foreliggende opfindelse angår en fremgangsmåde til fremstilling af stærkt oxiderende/desinficerende radikaler ved in-situ behandling af ozon med ultralyd.The present invention relates to a process for the preparation of highly oxidizing / disinfecting radicals in the in situ treatment of ozone with ultrasound.

Kombination af ultralyd og kemiske desinfektanter har i en del tilfælde vist sig at være mere effektiv, end hvis disse anvendes sær-skilt. Kombinationen vides at være fordelagtig, når den anvendes til ~~ sterilisation af luftbårne mikroorganismer samt mikroorganismer, der q er adhæderet til genstande. Kombinationen vides at have fordelagtig O effekt, både når den kemiske desinfektant og ultralyd anvendes sam- J- — tidig, og nar de anvendes forskudt, dvs. ultralyd som forbehandling og den kemiske desinfektant som efterbehandling. Dette menes at ^ bero på, at ultralyd dispergerer klumper af mikroorganismer og således forøger kontaktfladen mellem mikroorganisme og kemisk desinfektant.In some cases, the combination of ultrasound and chemical disinfectants has proved to be more effective than if used separately. The combination is known to be advantageous when used for sterilizing airborne microorganisms as well as microorganisms that are q adhered to objects. The combination is known to have beneficial 0 effect, both when the chemical disinfectant and ultrasound are used at the same time and when used staggered, ie. ultrasound as a pre-treatment and the chemical disinfectant as a post-treatment. This is believed to be due to the fact that ultrasound disperses clumps of microorganisms, thus increasing the interface between microorganism and chemical disinfectant.

En forøgelse af mikroorganismernes membranpermeabilitet har også været nævnt som sandsynlig mekanisme for denne såkaldte synergistiske 143891 - 2 - effekt. Det er også kendt, at behandling af medier indeholdende opløste eller suspenderede stoffer og/eller mikroorganismer bevirker, at disse ingredienser bliver mere modtagelige for behandling med ozon. Således er det offentliggjort, at spildevand, der behandles med ultralyd, ozoneres mere effektivt end ved ozonering uden ultralyd. Dette er ligeledes forklaret ved ultralyds mekaniske vibrationer og deres virkning på spildevandets mikroorganismer (dispergeres) og makromolekyler (slås i stykker under dannelse af mindre molekyler).An increase in membrane permeability of the microorganisms has also been mentioned as a likely mechanism for this so-called synergistic effect. It is also known that treating media containing dissolved or suspended substances and / or microorganisms makes these ingredients more susceptible to ozone treatment. Thus, it has been published that wastewater treated with ultrasound is ozonated more efficiently than by ultrasonic ozonation. This is also explained by the mechanical vibrations of ultrasound and their effect on the microorganisms of the wastewater (dispersed) and macromolecules (broken down to form smaller molecules).

Det er endvidere beskrevet, at gasarter, der er innaktive overfor en ønsket kemisk eller bakteriologisk proces, kan aktiveres ved hjælp af ultralyd, hvis reaktionsmediet er underkastet meget høje tryk, f.eks. 100-200 atmosfærer. Under disse forhold kan ultralyd aktivere f.eks. ilt eller carbondioxid og få disse til at reagere, hvad de ellers ikke uør uden anvendelse af ultralyd og det høje tryk. Man mener dette skyldes, at ultralyd og det høje tryk kan omdanne f.eks. ilt til ozon og således producere ozon in situ.It has also been described that gases which are inactive against a desired chemical or bacteriological process can be activated by ultrasound if the reaction medium is subjected to very high pressures, e.g. 100-200 atmospheres. Under these conditions, ultrasound can activate e.g. oxygen or carbon dioxide and cause them to react what they otherwise would not do without the use of ultrasound and the high pressure. This is believed to be because ultrasound and high pressure can transform e.g. oxygen to ozone and thus produce ozone in situ.

Den foreliggende opfindelse har til formål at forøge ozoneringens effektivitet ved ozonbehandling af et medium, der skal behandles eller som indeholder stoffer eller genstande, der skal behandles, under samtidig anvendelse af ultralyd.The present invention aims to increase the efficiency of ozonation in ozone treatment of a medium to be treated or containing substances or articles to be treated, while using ultrasound simultaneously.

Det er også opfindelsens formål at opnå en besparelse i den an-. vendte ultralydenergi.It is also the object of the invention to achieve a saving in the other. turned ultrasonic energy.

Det har nu overraskende vist sig, at dette kan opnås, når ozongas-boblerne behandles med ultralyd in situ, og opfindelsen er således ejendommelig ved, at ozongasindblæsningen er koncentreret i et ultralydfelt.It has now surprisingly been found that this can be achieved when the ozone gas bubbles are treated with ultrasound in situ, and the invention is thus characterized by the fact that the ozone gas supply is concentrated in an ultrasonic field.

Ved fremgangsmåden ifølge opfindelsen tilføres ozongasboblerne i et ultralydfelt i forbindelse med indblæsning og eventuel indpiskning i et flydende medium. Herved opnås en stor besparelse af ultralydenergien, idet den ultralydeffekt, som mediet gennemsnitligt udsættes - 3 - 143691 for, vil være lille. Samtidig vil den tilførte ozonmængde være udsat for en stor ultralydeffekt, da ozonkoncentrationen er størst i den tilførte gasblanding, dvs. i gasboblerne.In the method according to the invention, the ozone gas bubbles are supplied in an ultrasonic field in connection with blow-in and possible whipping in a liquid medium. This results in a great saving of the ultrasonic energy, since the ultrasonic power to which the medium is exposed - 3 - 143691 will be small. At the same time, the amount of ozone supplied will be subject to a large ultrasonic effect, since the ozone concentration is greatest in the gas mixture supplied, ie. in the gas bubbles.

Tilførslen af gasblandingen kan ske på iøvrigt kendt måde, f.eks. som direkte tilførsel af en ozonholdig gasblanding via diffusere i mediet eller som partiel injektionsdosering, hvorved den ozonholdige gas injiceres i en grenledning af vand, hvorpå blandingen af ozon/ gas/væske føres videre til hovedbeholderen, der indeholder det medie, der skal behandles.The supply of the gas mixture can be effected by other known means, e.g. as direct delivery of an ozone-containing gas mixture via diffusers into the medium or as a partial injection dosage, whereby the ozone-containing gas is injected into a branch line of water, whereupon the ozone / gas / liquid mixture is fed to the main container containing the medium to be treated.

Ozon er metastabilt og i de normalt foreliggende koncentrationer holdbart såfremt luften holdes helt fri for spor af urenheder. I forbindelse med fugt, varme, organiske stoffer og metaloxider af forskellig art de-komponerer ozon.Ozone is metastable and at normal concentrations durable if the air is kept completely free of traces of impurities. In the context of moisture, heat, organic matter and metal oxides of various kinds, ozone decomposes.

Dekomponeringen vides at foregå i flere trin, hvoraf nogle er radikal-dannende, og andre er radikalforbrugende. Radikalerne er højst reaktive og i fravær af oxiderbare stoffer, kan de reagere indbyrdes eller med ozonmolekyler, således at slutproduktet oxygen dannes.The decomposition is known to take place in several steps, some of which are radical-forming and others are radical-consuming. The radicals are highly reactive and in the absence of oxidizable substances, they can react with each other or with ozone molecules to form the final product oxygen.

De radikaldannende dekomponeringsprocesser kan til en vis grad frem-skyndes ved katalyse (metaloxider m.v.) eller ved tilførsel af aktiveringsenergi, f.eks. i form af varmenergi, som bestrålingsenergi, f.eks. i form af UV-lys eller ioniserende stråling, og/eller som ultralydenergi .The radical-forming decomposition processes can be accelerated to some extent by catalysis (metal oxides, etc.) or by the application of activation energy, e.g. in the form of heat energy, such as radiation energy, e.g. in the form of UV light or ionizing radiation, and / or as ultrasonic energy.

Ved ifølge opfindelsen at udsende ultralydbølger i ozongas-boblerne opnås en gas, der er rig på radikaler og/eller aktiverende ozonmolekyler.By emitting ultrasonic waves in the ozone gas bubbles according to the invention, a gas is rich in radicals and / or activating ozone molecules.

De radikalforbrugende processer påvirkes ikke eller påvirkes kun i ringe omfang. Ved videre inpiskning af disse ultralydaktiverende bobler i vandet opnås større udnyttelse af den producerede og indblæste ozonmængde. Samtidig opnår man, at faste partikler ikke dispergeres eller kun dispergeres i mindre omfang, samt at større molekyler ikke slås i stykker, som tilfældet ville være, hvis man behandlede hele mediet med ultralyd.The radical-consuming processes are not affected or only slightly affected. By further whipping these ultrasound-activating bubbles into the water, greater utilization of the produced and inflated ozone is achieved. At the same time, solid particles are not dispersed or only dispersed to a lesser extent, and larger molecules are not broken, as would be the case if the whole medium was treated with ultrasound.

Ved fremgangsmåden ifølge opfindelsen kan man desuden nøjes med betydelig mindre ultralydenergiforbrug end ved tidligere kendte fremgangsmåder, der har anvendt en kombination af ozon og ultralyd.In addition, the method according to the invention allows for considerably less ultrasonic energy consumption than previously known methods which have used a combination of ozone and ultrasound.

- 4 - 143691- 4 - 143691

Den simpleste udførelsesfonn for fremgangsmåden ifølge opfindelsen består i at sænke en ultralydsonde ned under væskeoverfladen i en reaktor, hvor tilførslen af en ozonholdig gas er særlig koncentreret under ultralydsonden. Injektorens eller diffusorens placering i ultralydfeltet er ifølge opfindelsen af afgørende betydning for den opnåede kombinationseffekt af ozon/ultralydbehandlingen. Desuden kan det ifølge opfindelsen være hensigtsmæssigt at sørge for en effektiv omrøring, således at de ultralydbehandlede ozonbobler findeles og spredes mest og hurtigst muligt i den øvrige flydende fase, som ikke nødvendigvis er under direkte indvirkning af ultralyden. Det kan ifølge opfindelsen også være hensigtsmæssigt at lade reaktoren gennemstrømmes af væsken. Det kan ligeledes være hensigtsmæssigt, at ultralydbestråling- og ozonindblæsningsorganer installeres i reaktorens bund eller sider med eller uden ultralydreflekterende flader.The simplest embodiment of the process according to the invention consists in lowering an ultrasonic probe below the liquid surface in a reactor, where the supply of an ozone-containing gas is particularly concentrated under the ultrasonic probe. The position of the injector or diffuser in the ultrasonic field is, according to the invention, of crucial importance for the combined effect of ozone / ultrasonic treatment obtained. In addition, according to the invention, it may be convenient to provide effective agitation so that the ultrasonic ozone bubbles are comminuted and dissipated as quickly as possible in the other liquid phase, which is not necessarily under the direct influence of the ultrasound. According to the invention it may also be appropriate to allow the reactor to flow through the liquid. It may also be appropriate for ultrasonic irradiation and ozone supply means to be installed in the bottom or sides of the reactor with or without ultrasonic reflecting surfaces.

Ifølge opfindelsen kan det også være hensigtsmæssigt, at diffusoren og ultralydsonden er sammenkoblet som en ultralyddiffusor eller ultralydinjektor.According to the invention, it may also be convenient for the diffuser and the ultrasonic probe to be interconnected as an ultrasonic diffuser or ultrasonic injector.

Opfindelsen angår desuden et apparat til udøvelse af fremgangsmåden ifølge opfindelsen, hvilket apparat omfatter en beholder, evt. med væske ind- og udløb, en ultralydskilde og ozongastilførsel, og dette apparat er ejendommeligt ved, at gastilførselsledningen udmunder i lydfeltet.The invention further relates to an apparatus for carrying out the method according to the invention, which apparatus comprises a container, possibly with liquid inlets and outlets, an ultrasonic source and ozone supply, and this device is peculiar in that the gas supply line opens into the sound field.

Hvis apparatet ifølge opfindelsen skal anvendes til sterilisation af genstande, såsom kirugiske utensilier, har det endvidere ifølge opfindelsen vist sig særlig fordelagtigt, at gastilførslen sker via en kombineret ultralyds-diffusor-sonde, og at apparatet indeholder en kurv til understøtning af genstandene.Furthermore, if the apparatus according to the invention is to be used for sterilizing objects, such as surgical utensils, it has been found particularly advantageous according to the invention that the gas supply is via a combined ultrasonic diffuser probe and that the apparatus contains a basket for supporting the articles.

Apparatet ifølge opfindelsen skal forklares nærmere under henvisning til tegningen, på hvilken fig. 1 viser et batchsystem, hvor ozongasbobler sendes mod ultralydbølger i reaktorens midte.The apparatus according to the invention will be explained in more detail with reference to the drawing, in which FIG. Figure 1 shows a batch system in which ozone gas bubbles are transmitted against ultrasonic waves in the center of the reactor.

- 5 - 143691 fig. 2 viser samme opstilling som fig. 1 dog som en kontinuerligt gennemstrømmet reaktor, fig. 3 viser en gennemstrømmet flertrinsreaktor, hvor ultralyd genereres ved bunden, hvor ozonboblerne også indblæses, fig. 4 viser en kombineret ultralyd-diffusorsonde, der er installeret i bunden af reaktoren, fig. 5 viser en forsøgsopstilling med en gennemstrømningsreaktor, og fig. 6 viser en grafisk illustrering af variationen i reduktionsfaktor og elektrokemisk potentiale ved forskellige forsøgsbetingelser.FIG. 2 shows the same arrangement as FIG. 1, however, as a continuously flowing reactor; FIG. Fig. 3 shows a multistage reactor flowing where ultrasound is generated at the bottom, where the ozone bubbles are also blown in; 4 shows a combined ultrasonic diffuser probe installed at the bottom of the reactor; FIG. 5 shows an experimental set-up with a flow reactor; and FIG. 6 shows a graphical illustration of the variation in reduction factor and electrochemical potential under different experimental conditions.

Ultralydbehandling af ozonboblerne er illustreret i figurerne 1-4.Ultrasonic treatment of the ozone bubbles is illustrated in Figures 1-4.

Por alle disse simplificerede opstillinger gælder, at der til en reaktor (1), der indeholder en væske (2), f.eks. vand, tilføres en ozongasblanding (3) i et ultralydfelt (4). Feltet skabes af en ultralydsgenerator, hvoraf kun en sonde (5) fremgår af tegningen. En omrøringsanordning (6) er vist i figurerne 1 og 2. Opstillingerne på figur 2 og 3 er gennemstrømmet af såvel gasblandingen (3) som af væsken (2). I figur 4 anvendes en særlig sonde (7), hvor ozongasind-blæsningen og ultralydsgenereringen er bragt tæt ved hinanden for at opnå stor effekt med en simpel udførelsesform. Reaktoren på fig. 4 rummer mulighed for at anbringe genstande (8), der skal renses, desinficeres eller steriliseres, f.eks. instrumenter.For all these simplified arrangements, a reactor (1) containing a liquid (2), e.g. water, an ozone gas mixture (3) is fed into an ultrasonic field (4). The field is created by an ultrasonic generator, of which only one probe (5) is shown in the drawing. A stirrer (6) is shown in Figures 1 and 2. The arrangements of Figures 2 and 3 are flowed by both the gas mixture (3) and the liquid (2). In Figure 4, a special probe (7) is used, where the ozone gas blow-in and ultrasonic generation are brought close to each other to achieve great power with a simple embodiment. The reactor of FIG. 4 provides the possibility of placing objects (8) to be cleaned, disinfected or sterilized, e.g. instruments.

I de viste udførelsesformer er kun anvendt indblæsning af ozongas i forbindelse med ultralydsonden, men der er intet til hinder for at sprede ozonindblæsningen eller sprede ultralydfeltet over større areal i reaktoren.In the embodiments shown, only ozone gas is used in conjunction with the ultrasonic probe, but there is nothing to prevent the ozone blow-in or the ultrasonic field over a larger area of the reactor.

For at dokumentere, at det er muligt at øge ozoneringens effektivitet ved at ultralydbehandle ozongasboblerne in situ, dvs. i forbindelse med indføring til det medie, der skal behandles, eller som indeholder stoffer eller genstande, der skal behandles, er der udført følgende eksperiment:To prove that it is possible to increase the efficiency of ozonation by ultrasonic treatment of the ozone gas bubbles in situ, ie. in connection with introduction to the media to be treated or containing substances or articles to be treated, the following experiment was performed:

Til en gennemstrømningskuvette ledes kontinuerligt ved hjælp af en peristaltikpumpe overfladevand hentet fra Emdrup Sø (130ml/min).To a flow cuvette is continuously fed surface water from Emdrup Lake (130ml / min) using a peristaltic pump.

» - 6 - 143691»- 6 - 143691

Kuvetten er forsynet med en ultralydsonde, hvorunder gassen tilføres ved hjælp af en kanyle med et konstant flow (60 ml/min.)· I kuvetten registreres redoxpotentialet E automatisk ved hjælp af et pH-meter og en skriver. Opstillingen er vist på fig. 5, hvor (1) betegner en ultralydsonde, (2) betegner en gennemstrømningsreaktor, (3) betegner en peristaltikpumpe, og (4) er en kolomel/platinelektrode.The cuvette is equipped with an ultrasonic probe, under which the gas is supplied by means of a cannula with a constant flow (60 ml / min) · In the cuvette, the redox potential E is automatically detected by means of a pH meter and a printer. The arrangement is shown in FIG. 5, where (1) denotes an ultrasonic probe, (2) denotes a flow reactor, (3) denotes a peristaltic pump, and (4) is a columel / platinum electrode.

Ved forsøget måles mediets oxiderende potentiale samt E.coli-koncen-trationen som fuktion af ilt og ozondosering med og uden ultralyd. Forsøgsbetingelserne og de registrerede værdier er angivet i den efterfølgende Tabel I og i fig. 6.In the experiment, the oxidative potential of the medium as well as the E. coli concentration is measured as the oxygen and ozone dosing with and without ultrasound. The test conditions and the recorded values are given in the following Table I and in FIG. 6th

Forsøget viser således at behandling af iltbobler med ultralyd ikke medfører nogen effekt hvad angår mediets elektrokemiske potentiale og desinficerende effekt.Thus, the study shows that treating oxygen bubbles with ultrasound has no effect on the electrochemical potential and disinfecting effect of the medium.

I modsætning hertil virker ozon til en vis grad desinficerende, men redox-potentialet forbliver under de pågældende omstændigheder uændret. Ultralydbehandling af ozon viser derimod en kraftig forøgelse både af -redoxpotentialet og af den desinficerende effekt.In contrast, ozone does to some extent disinfect, but the redox potential remains unchanged in those circumstances. Ozone ultrasound treatment, on the other hand, shows a sharp increase in both the redox potential and the disinfectant effect.

I henhold til de herved vundne erfaringer må det derfor konkluderes, at man kan kombinere ultralyd og ozon, som beskrevet i denne patentansøgning, og herved opnå en favorabel effekt, som ikke kan opnås, hvis processen udføres med ilt og ultralyd.According to the experience gained from this, it must therefore be concluded that ultrasound and ozone can be combined, as described in this patent application, and thereby obtain a favorable effect which cannot be achieved if the process is carried out with oxygen and ultrasound.

Det kan dog ikke udelukkes, at mediet kan gøres oxiderende og desinficerende med ilt og ultralyd, dersom man bruger usædvanlig høje ultralydintensiteter og/eller meget høje tryk.However, it cannot be ruled out that the medium can be oxidized and disinfected with oxygen and ultrasound if exceptionally high ultrasound intensities and / or very high pressures are used.

I sammenligning hermed udmærker fremgangsmåden ifølge opfindelsen sig ved at være betydelig mere simpel og energibesparende.In comparison, the method according to the invention stands out by being considerably more simple and energy-saving.

Fremgangsmåden ifølge opfindelsen, der udnytter en kombination af ozon og ultralyd, har en række potentielle anvendelsesområder. Således kan vand renses for enhver art af visse stoffer og/eller mikroorganismer.The process of the invention utilizing a combination of ozone and ultrasound has a number of potential applications. Thus, water can be purified for any kind of certain substances and / or microorganisms.

Desuden kan vand eller andre væsker behandles som led i en serie af behandlingsprocesser. De frie radikaler kan f.eks. angribe en del refraktære stoffer såsom humus, og ændre disse stoffers karakter, således at de bliver lettere biologisk nedbrydelige, lettere udfældelige, mindre formede og/eller mindre giftige.In addition, water or other fluids can be treated as part of a series of treatment processes. The free radicals can e.g. attack some refractory substances such as humus, and change the nature of these substances so that they become more readily biodegradable, more easily precipitated, less formed and / or less toxic.

Endvidere kan metoden anvendes til behandling af selve det likvide medie, f.eks. olie, eller til behandling af genstande som anbringes i mediet, f.eks. til desinfektion og rensning af utensilier eller affarvning af papir og tekstilmasser.Furthermore, the method can be used to treat the liquid medium itself, e.g. oil, or for treating objects placed in the medium, e.g. for disinfecting and cleaning utensils or decolorizing paper and textile pulp.

De frie radikaler kan ligeledes være et værdifuldt redskab indenfor kemisk præparation og syntese.The free radicals can also be a valuable tool in chemical preparation and synthesis.

Kombinationen kan også benyttes til nedbrydelse af et eventuelt ozonoverskud i et medium.The combination can also be used to decompose any ozone excess in a medium.
