Description

Elektrodiaphragmalyse electrodiaphragmalysis
Die Elektrolyse bezeichnet das Teilgebiet der Elektrochemie, das sich mit den Erscheinungen befasst, die auftreten, wenn Chemikalien mit Strom behandelt werden (im Gegensatz zur Galvanik, die Strom aus Chemikalien gewinnt). Der Bereich der Elektrolyse umfasst die Elektronenanregung (Leuchten von Gasen) bei geringen Stromintensitäten bis zur Zerstörung (Lyse) bei hohen Stromintensi- täten.Electrolysis is the branch of electrochemistry that deals with the phenomena that occur when chemicals are treated with electricity (as opposed to electroplating, which extracts electricity from chemicals). The field of electrolysis includes the electron excitation (illumination of gases) at low current intensities to destruction (lysis) at high current intensities.
Die Form der Elektrodiaphragmalyse hat zwischen anodischen und kathodischen Bereich eine poröse Membran gelagert, die ein Übertreten und Vermischen der an der Anode und an der Kathode entstehenden Gase verhindern soll. Diese Gase (Sauerstoff und Chlor gas an der Anode und Wasserstoff an der Kathode) bilden beim Zusammentreffen explosive Gemische: Sauerstoff und Wasserstoff, das sogenannte Knallgas, Chlorgas und Wasserstoff, das sogenannte Chlor-Knallgas. Das Diaphragma ist damit ein Explosionsschutz, der bereits 1886 eingeführt wurde. Die alternative Methode ist das Amalgam- Verfahren, bei dem die Kathode aus durchfließendem Quecksilber besteht, das die an ihm entstehenden Spaltprodukte mitreißt. Wegen des offenen Quecksilbers keine praktikable Möglichkeit.The shape of the electro-diaphragm analysis has a porous membrane between the anodic and cathodic regions, which is intended to prevent overflow and mixing of the gases produced at the anode and at the cathode. These gases (oxygen and chlorine gas at the anode and hydrogen at the cathode) form when they meet explosive mixtures: oxygen and hydrogen, the so-called oxyhydrogen, chlorine gas and hydrogen, the so-called chlorine oxyhydrogen. The diaphragm is thus an explosion protection, which was already introduced in 1886. The alternative method is the amalgam process, in which the cathode consists of mercury flowing through, which entrains the fission products formed on it. Because of the open mercury not a viable option.
Im Stand der Technik werden anodischer und kathodischer Raum gleichzeitig und in gleicher Strömungsrichtung mit dem gleichen Elektrolyt durchströmt; (siehe DVGW Arbeitsblatt W229 und Fig. 1). Das Diaphragma erlaubt zwei Teilströme getrennt zu gewinnen (Anodische Fraktion = Anolyt und kathodische Fraktion = Katholyt). Das erfindungsgemäße Produkt hat eine größere Wirksamkeit gegenüber Mikroorganismen als aufgrund seines Gehaltes an chemischen Substanzen (Natriumhypochlorit) zu erwarten ist. Dies liegt an seiner oxidativen Kraft, der Eigenschaft als Elektronenakzeptor zu agieren, was wiederum an einem hohen Elektronen- mangel in der Wassermatrix (Cluster) liegt. Diese wird erzielt durch eine besondere Version der Elektrodiaphragmalyse.In the prior art, anodic and cathodic space flows through the same electrolyte simultaneously and in the same flow direction; (see DVGW worksheet W229 and Fig. 1). The diaphragm allows two partial streams to be collected separately (Anodic fraction = anolyte and cathodic fraction = catholyte). The product according to the invention has a greater activity against microorganisms than is to be expected on the basis of its content of chemical substances (sodium hypochlorite). This is due to its oxidative power to act as an electron acceptor, which in turn is due to a high electron deficiency in the water matrix (cluster). This is achieved by a special version of the electro-diaphragm analysis.
Dabei wird Wasser einer schwachen Stromintensität ausgesetzt. Dazu wird dem Wasser z.B. Kochsalz zugesetzt, um die Leitfähigkeit des Wassers in einem für den Vorgang optimalen Bereich zu halten. Die zugesetzte Menge sind ca. 0,2 bis 0,6 % bzw. 2 bis 6 g/L Es werden Platten-Elektroden verwendet, die zwischen sich ein homogenes Feld paralleler Feldlinien erzeugen, sodass die Feldstärke an allen Stellen im Zwischenraum gleich ist. So erfolgt eine homogene, eng begrenzte Elektrolyse im Sinne der Elektronenanregung. Das Elektrolyt wird mit konstan- ter Flussgeschwindigkeit von z.B. 140 l/h (bezogen auf eine 100 l/h Produktionszelle) zunächst durch den von der Kathode und dem Diaphragma gebildeten kathodischen Raum geleitet. Die Behandlung erfolgt mit vorzugsweise 15-30 Ampere. Es entsteht ein alkalisches Katholyt bei starker Gas-Bildung vor allem Wasserstoff-Gas. Die kathodische Fraktion wird dann in einen größeren Raum geleitet, der zum Entgasen dient. Durch die plötzliche Vergrößerung des Raumes kommt es zur Reduktion der Fließgeschwindigkeit und die Gasblasen können sich abscheiden. Unterstützt wird dieser Prozess durch als Koaleszer wirkende Strukturen im Flüssigkeitsstrom, wie z.B. Waben; siehe beiliegende Fig 2.This water is exposed to a low current intensity. For this the water is e.g. Salt is added to keep the conductivity of the water in an optimum range for the process. The added amount is approx. 0.2 to 0.6% or 2 to 6 g / L. Plate electrodes are used which generate a homogeneous field of parallel field lines between them so that the field strength is the same at all points in the intermediate space. Thus, there is a homogeneous, narrowly limited electrolysis in the sense of electron excitation. The electrolyte is stirred at a constant flow rate of e.g. 140 l / h (based on a 100 l / h production cell) first passed through the cathodic space formed by the cathode and the diaphragm. The treatment is carried out with preferably 15-30 amps. The result is an alkaline catholyte with strong gas formation, especially hydrogen gas. The cathodic fraction is then sent to a larger room for degassing. The sudden enlargement of the space leads to a reduction of the flow velocity and the gas bubbles can separate out. This process is assisted by structures acting as coalescers in the liquid stream, e.g. honeycomb; see enclosed Fig. 2.
Zwischen 10% und 50%, in der Regel 30% des Katholyts, schwämmt die Gasblasen aus und verlässt das System über die Drainage. Die restlichen 50 bis 90% werden in die anodische Kammer geführt, sodass sie diese im Gegenstrom zur kathodischen Kammer durchfließen. So wird der pH Wert auf pH 7 eingestellt. Die angeregten Elektronen wandern durch das Diaphragma in den kathodischen Raum; die elektronenarme Anolyt-Fraktion kann gewonnen werden. Das erfindungsgemäße Verfahren beruht auf einer Weiterentwicklung des Verfahrens der Elektrolyse. Mittels Kochsalz wird eine definierte Leitfähigkeit in Wasser erreicht. Durch Anlegen einer bestimmten Spannung in der Elektrolysezelle, sowie durch Justierung anderer wichtiger Parameter bei der Herstellung, werden die Wassercluster (zusammenhängende Wassermoleküle durch Magnetwirkung des Wassermoleküldipols) elektrisch entladen.Between 10% and 50%, usually 30% of the catholyte, lavages the gas bubbles and leaves the system via the drainage. The remaining 50 to 90% are fed into the anodic chamber, so that they flow through in countercurrent to the cathodic chamber. So the pH is adjusted to pH 7. The excited electrons travel through the diaphragm into the cathodic space; the electron-deficient anolyte fraction can be recovered. The inventive method is based on a further development of the method of electrolysis. By means of common salt, a defined conductivity in water is achieved. By applying a certain voltage in the electrolytic cell, as well as by adjusting other important parameters in the production, the water clusters (contiguous water molecules by magnetic action of Wassermoleküldipols) are electrically discharged.
Es entstehen positiv geladene Wassercluster, die als Elektronenakzeptoren fungieren, der so genannte Elektronenhunger. Dieser sättigt sich an einem Elektronen- donator, z.B. jede Form von Einzellern.It creates positively charged water clusters that act as electron acceptors, the so-called electron starvation. This saturates at an electron donor, e.g. every form of unicellulars.
Das Verfahren unterscheidet sich grundlegend von einer klassischen Elektrolyse, die z.B. der Herstellung von Chlordioxid zugrunde liegt. Dabei wird ein vorliegendes Elektrolyt lysiert, also aufgetrennt und in Radikale zerlegt.The process is fundamentally different from traditional electrolysis, e.g. the production of chlorine dioxide is based. In this case, a present electrolyte is lysed, so separated and decomposed into radicals.
Auch die Elektrodiapliragmalyse, welche z.B. zur Herstellung von Natriumhypochlorit und anderer Oxidantien eingesetzt wird, ist ein solches zerlegendes Verfahren. Die Wirkung beruht auf der hergestellten Chlor chemie, welche im Anwendungsfall oxidierend auf die Umgebung reagiert. Die Wirkung der Erfindung beruht auf der Anregung des Wassermoleküls selbst. Dieses befindet sich in einem Clusterverbund, sodass durch Anlegen einer bestimmten Stromstärke Wassermoleküle elektrisch entladen werden (ähnlich wie bei einer Neonröhre, die durch Anregung der Elektronen des Edelgases zum Leuchten gebracht wird). Im Unterschied zu klassischen elektrolytischen Verfah- ren, welche als bewährte Methode bereits seit über 120 Jahren in unterschiedlichen Ausprägungen im Einsatz ist, wird bei der erfindungsgemäßen Herstellung das Wassermolekül nicht in seine Bausteine OH" und H+ zerlegt und bleibt pH- neutral (pH 7,0). Das Wassermolekül bleibt erhalten und tauscht die Ladungsträger innerhalb des Clusters ständig aus. Zwar entstellen bei der Herstellung geringe Mengen an Natriumhypochlorit, diese Verunreinigung des Wassers (je nach Konzentration 0,6 bis 600 ppm) ist jedoch in den meisten Praxisanwendungen tolerabel.The Elektrodiapliragmalyse, which is used for example for the production of sodium hypochlorite and other oxidants, is such a decomposing process. The effect is based on the produced chlorine chemistry, which reacts oxidizing in the application to the environment. The effect of the invention is based on the excitation of the water molecule itself. This is in a cluster compound, so that by applying a certain current water molecules are electrically discharged (similar to a neon tube, which is made by excitation of the electrons of the noble gas to light). In contrast to classical electrolytic processes, which has been used as a proven method for more than 120 years in various forms, in the preparation according to the invention the water molecule is not decomposed into its building blocks OH " and H + and remains pH-neutral (pH 7 , 0) The water molecule is retained and constantly exchanges the charge carriers within the cluster. Although small amounts of sodium hypochlorite disfigure during production, this contamination of the water (depending on the concentration 0.6 to 600 ppm) is tolerable in most practice applications.
Für sehr empfindliche Applikationen kann das oben beschriebene Verfahren auch zur Herstellung von Produkten herangezogen werden, welches keine Chlor basierten Reststoffe mehr enthält, sondern ausschließlich aus Wasser und Anteilen angeregter Wassermoleküle besteht.For very sensitive applications, the method described above can also be used for the production of products which no longer contains chlorine-based residues, but consists exclusively of water and portions of excited water molecules.
Nachweise des Elektronenmangels als oxidativer BiozidwirkstoffEvidence of electron deficiency as an oxidative Biocidwirkstoff
Röntgen stellt einen starken Elektroneneintrag dar. Dieser hat keine Wirkung auf z.B. eine Hypochloritlösung, die dadurch ihre mikrobiozide Wirkung nicht verliert. Das erfindungsgemäße Produkt dagegen verliert seine biozide Wirkung durch Röntgen völlig:X-ray represents a strong electron input. This has no effect on e.g. a hypochlorite solution that does not lose its microbiocidal activity. In contrast, the product according to the invention completely loses its biocidal effect by X-ray:
Versuch 1Trial 1
Es wurde beobachtet, dass Versuchslösungen, die mit dem Flugzeug verschickt wurden keine Wirkung hatten. Daraufhin wurde folgender Versuch durchgeführt. Lösung A wurde einer Röntgendosis unterworfen, die bei einem 1 -stündigen Flug von Frankfurt nach Berlin einwirkt. Geprüft wurde die Abtötung von E. coli im Mikrobiologischen Labor. Die Kontrolle wurde nicht geröngt, hat aber die Fahrten der Lösung A von Regensburg nach Wiesbaden und von dort zum Untersuchungslabor „mitgemacht". It was observed that trial solutions sent by plane had no effect. The following experiment was then carried out. Solution A was subjected to an X-ray dose, which acts on a 1-hour flight from Frankfurt to Berlin. The killing of E. coli in the microbiological laboratory was tested. The inspection was not x-rayed, but has the rides of the solution A of Regensburg to Wiesbaden and from there to the investigation laboratory "participated".
+ = Wachstum des Testkeims (Nachweis durch Subkultur) - = kein Wachstum+ = Growth of the test germ (detection by subculture) - = no growth
Testkeim: Escherichia coli Ausgangskeimzahl: 2,3 x 104 Test germ: Escherichia coli starting bacterial count: 2.3 x 10 4
Die Kontrolle hat auch bei nur 10%iger Lösung innerhalb von nur 1 min alle Keime abgetötet, es gab kein Wachstum. Der Transport hatte keinen Einfluss auf die Wirksamkeit.The control has killed all germs in only 10% solution in just 1 min, there was no growth. The transport had no effect on the effectiveness.
Lösung A hat auch in 50%iger Konzentration bei 5 min Einwirkdauer keine Wirkung gezeigt, wurde also durch den Elektroneneintrag beim Röntgen völlig deaktiviert.Solution A also showed no effect in 50% concentration at 5 min exposure time, so it was completely deactivated by the electron entry in the X-ray.
Versuch 2 Das erfindungsgemäße frische Produkt weist in einer 10%igen Lösung 25 ppm Hypochlorit auf (NADES).Experiment 2 The fresh product according to the invention has 25 ppm hypochlorite in a 10% solution (NADES).
Das in nachstehender Tabelle gezeigte NADES SC ist ein 10%iger NADES- Produkt dem das Hypochlorit völlig auf < 0,02 ppm entzogen wurde. Eine Hypochloritlösung dieser Konzentration hat keine mikrobiozide Wirkung. Die Re- doxpotentiale beider Lösungen waren dennoch nahezu gleich, jedenfalls deutlich über den für Badewasser-Sanierung geforderten 600 ppm. The NADES SC shown in the table below is a 10% NADES product with the hypochlorite completely removed to <0.02 ppm. A hypochlorite solution of this concentration has no microbiocidal activity. Nevertheless, the redox potentials of both solutions were almost the same, in any case significantly higher than the 600 ppm required for bathing water remediation.
Die mikrobiozide Wirkung beider Lösungen war gleich, es trat kein Wachstum auf, auch nach 4 Tagen nicht. Ein Beweis für die Wirksamkeit des Elektronenmangels. The microbiocidal activity of both solutions was the same, no growth occurred even after 4 days. A proof of the effectiveness of the electron deficiency.
