Die Erfindung betrifft ferner ein elektrocnemiscner Reaktor für Reinigung Deschmutzter Flussigkeiten. welcher Realtor aus Einem zur Zu- und Ableitung von Flüssigkeiten, z.B. The invention further relates to an electro-chemical reactor for cleaning contaminated liquids. which real gate from one for the supply and discharge of liquids, e.g.
Wasser dienenden Rohrstutzen versehenen Behälter und zwei im Behalter befindlichen , mit unterschiedlichen Durchmessern hergestellten, koaxial singebauten walzenförmigen Elektroden besteht, ferner ist der zwischep den Elektorden ausgebildete DispergierKammer mit durch Flächenberührung stattfindene Stromleitung geeignetem Granulat gefüllt.

Die es bekannt ist, werden zahlreiche Methoden für die Reinigung beschmutzter Wässer sngewendet. As is known, numerous methods are used for cleaning polluted water.
Die Reinwasservoräte der Erde stehen kurz vor Erschöpfung. Die sus der Industrie und haushalt herauskommenden Abwässer verderben die Wasserbasen - sogar auch nach einer Reinigung -, so müsste das wasser der Wasserbasen vor Verbrauch meistens gereinigt werden. Darum sind die wassersparenden Technologies die Anwendung von geschlossenen Wassersvteme und neue wasserreinigungsmethode in der letzten Zeit bevorzugt .
Die Anwendung von elektrochemischen Methoden in der Wasserreinigung - obwohl das Prinzio nicht neu ist - kommt neuerdings immer mehr in den Vordergrund. denn die Preise der Chemikalien erhöht werden. gleichzeitig entstehen umweltfremde Nebenprodukte im grossen Mae, welcher Behandlung und Lagerung weitere Sargen involviert. The world's pure water supplies are on the verge of exhaustion. The wastewater coming out of industry and households spoil the water bases - even after cleaning - so the water in the water bases would usually have to be cleaned before use. That is why the water-saving technologies have preferred the use of closed water systems and new water purification methods in recent times. The use of electrochemical methods in water purification - although the prince is not new - has recently come to the fore. because the prices of the chemicals are increased. At the same time, non-environmental by-products are produced to a large extent, which treatment and storage involves further coffins.
Die elektrochemischen Methoden haben einen gemeinsamen Charakter. und zwar das beschmutzte Wasser soll als Elektrolit betrachtet werden, in welchem phisikalische und chemiscne Wandlungen bei Stromzuleitung eintreten, die die Entfernung der Schmutzstoffe ermöglichen. The electrochemical methods have a common character. namely the polluted water should be regarded as an electrolite, in which physical and chemical changes occur when the power supply line, which enable the removal of the contaminants.
Im Urheberschein Nr. SU 893.884 ist ein Reaktor für Reinigung von mit Schwermetallen beschmutzten Wasser beschrieben. Dieser Reaktor besteht aus einem Behälter mit Zu- und Ableitungsrohrstutzen um die Flüssigkeit zu- und ableiten zu können, ferner aus im Innenraum des Behälters befindlichen Elektroden. Der Raum zwischen den beiden Elektroden wird mit einem Diaohraqma in Katodenraum und Anodenraum aufgeteilt. Im Anodenraum befindet sich ein Anod und im Katodenraum befinden sich zwei Katoden. Eine der Katoden wird aus lösbarem Metall, die andere aus nicht lösbarem Metall hergestellt. Copyright document No. SU 893.884 describes a reactor for cleaning water contaminated with heavy metals. This reactor consists of a container with inlet and outlet pipe stubs in order to be able to supply and discharge the liquid, and also electrodes located in the interior of the container. The space between the two electrodes is divided into a cathode compartment and anode compartment using a diaohraqma. There is one anode in the anode compartment and two cathodes in the cathode compartment. One of the cathodes is made of removable metal, the other of non-removable metal.
Ein hangel dieses Reaktors besteht darin, daß der Vorgang des elektrochemischen Prozesses zu langsam ist. weil die Oberflächen der Elektroden zu klein sind und diese Oberflächen im Laufe des Prozesses durch den Prozess passiviert werden, infolgedessen die Stromdichte und damit die Produktivität abnehmen.

Die Bohrung an der Achse der inneren Elektrode ist ein Hohlraum. welche mit der Dispergierkammer durch an der oberen Seite der Elektrode ausgebildete Spalte verbunden ist und auch auf die Ableitung des aus der Dispergierkammer strömenden Wassere dient. A drawback of this reactor is that the electrochemical process is too slow. because the surfaces of the electrodes are too small and these surfaces are passivated in the course of the process, as a result the current density and thus the productivity decrease. The reactor described in the authorship certificate No. SU 8% .885 abolishes the aforementioned almonds. Roller-shaped electrodes are installed in a coaxial arrangement in the vessel of the reactor. The space between the electrodes, the so-called dispersion chamber, is filled with conductive granules. The one between the outer electrode and the container wall is the suction. Cooling compensation chamber, which is connected to the dispersion chamber through the gaps formed on the lower side of the outer electrode. The bore on the axis of the inner electrode is a cavity. which is connected to the dispersion chamber by gaps formed on the upper side of the electrode and also serves to discharge the water flowing out of the dispersion chamber.
Obwohl der Wirkungsgrad durch diesen Reaκtor verbessert wird, hat der Reaktor zahlreiche Mängel. Die vollkommene und gleichmäßi'ge Teilnahme des Granulates im Prozeß wird durch die Konstruktion nicht dewährleistet , das Granulat wird sich mit der Zeit verdichtet und zusammengepreßt und so wird derhydraulische Wiederstand des Reaktors vergrbßert. Gleichzeitig wird die Eletktrode von guter Qualität wegen der anodischen Losung verzehrt . Die Reinigungsprozeß wird wegen der aufgezählten Mngel instabil, der Wirkungsgrad nimmt ab und der spezifischer Energieaufwand wächst zu.

10 durch den zuleitengen Rohrstutzen Z in den Reakto r geleitet υnd gleichzeitig werden die Elekt roden 6,7 durch die Stromleiter 21.22 mit Strom gesbeist . Die beschmutztes Flussigkeit strömt die Disdergierka mmer 10 und die innere Seite der Isolierbuchse 16 durch, d.h. die Flüssigkeit macht eime gegenströmende Bewegung im Verchalthis zur Bewegung des Granulates 9. In den Punkt en . wo die einzelnen körnchen des Granulates 9 einander zerühren. ehtstehen Lichtbogenentladungen, die die k örnchen in den Berührungpunk ten bis zum Schmelzpunkt erhitzen. Die rerschm älzten k örnchen werden im Wasser dispergiert und das Wasser wird in seine Ak tivelemente (H+ és OH-) dissorliert . Gleichzeitig werden die verunreinigungen der Flussigkeit such ak tiviert und so ergibt eine Zunahme ihrer Rsaktionsfähigk eit. Die Abscheidung der Verunreinigungen erfolgt im Laufe der Ox ydations- und Reduk tionsprozesss, die zwischen den Ak tivelementen des Wassers und oxydierten d isoergierten M etellen stattfinden. Diese Prozesse sind im allgemeinen mit koagulations- und Absorttionsbrozessen v sr bunden . According to the invention, the method is, for example, more specific. Electrochemical reactor as follows: the current-carrying granulate 9 can be made from waste left behind by hetal processing. Broken soy. etc. are produced .. The protected liquid core is filled with the disdergier chamber 10 through the feed pipe Z in the reactor r and simultaneously the electrodes 6, 7 are supplied with current by the current conductors 21.22. The contaminated liquid flows through the Disdergierka chamber 10 and the inner side of the insulating bush 16, ie the liquid makes a countercurrent movement in the Verchalthis to move the granules 9. In the point en. where the individual granules of the granules 9 stir together. There are arc discharges that heat the granules in the contact points to the melting point. The milled granules are dispersed in the water and the water is dissorlated into its active elements (H + és OH-). At the same time, the contamination of the liquid is activated and an increase in its reactivity results. The separation of the impurities takes place in the course of the oxidation and reduction process, which take place between the active elements of the water and oxidized, disaggregated metals. These processes are generally associated with coagulation and absorption processes.

Gal vanbetrieben sehr oft vorko mmenden. sehr tox ischen secnswerti gen Ch roms bei Anwendung des er fingdung sgemaßen R esk tore beka nnt gemach t:
Das toxiscne sechswertige Chrom wird in einem nicht toxischen dreiwertigen Chrem reduziert und bildet such Hydroxid . Das sich sehr gut setzende Eisen (III) hycroxid absorbiart das sich sehr schlecht setzende Chromhydroxid und so kann beide im nach dem Reaktor geschalteten Absetzer abgeschieden werden. Das Prozeß spielt sich bei anderen Metallen auch ähnlich ab. Gal vans occur very often. very toxic secrets of chromium are known when using the appropriate escapes: The toxic hexavalent chromium is reduced in a non-toxic trivalent chromium and also forms hydroxide. The iron (III) hydroxide, which settles very well, absorbs the chromium hydroxide, which settles very poorly, and so both can be separated in the settler connected after the reactor. The process is similar for other metals.
Es ist einzusehen. daβ die Füllmaterial bildenden Metalloder Eisenkörnchen erstarren würden (etwa zusammenwachsen würden). wenn sie im erf indungsgemäβen Reaktor nicht ständig gerührt werden. Die in der Sammelkammer 11 abgesetzte Körnchen werden mit der Rührschaufel 20 vermischt und zur Förderschnecke 17 geleitet, die die Körnchen durch den Well enhohlraum 15 in die Rührkammer 14 hebt. Eine derartige Zirkulation des Granulates 9 hat zur Folge. daß die Abmessungen der Körnchen durchschnittlich werden. es kommt keine Schichtenbildung und Zusammenk lebung vor. so wird der hydraulische Widerstand des Reaktors nicht wachsen, werden die elektrischen. Parameter ständig und wird der Betrieb des Reaktors stabilisiert. Schlieβlicn wird eine grdßere Reinigungskapazi tät mit einem geringeren Energieaufwand gesichert. It can be seen. that the filler metal or iron granules would solidify (would grow together). if they are not constantly stirred in the reactor according to the invention. The granules deposited in the collecting chamber 11 are mixed with the stirring blade 20 and passed to the screw conveyor 17, which lifts the granules through the wave cavity 15 into the stirring chamber 14. Such a circulation of the granules 9 results. that the dimensions of the granules become average. there is no stratification and cohabitation. so the hydraulic resistance of the reactor will not grow, the electrical ones. Parameters constantly and the operation of the reactor is stabilized. Finally, a larger cleaning capacity is ensured with less energy consumption.
