Description
Die Erfindung betrifft korrosionsbeständige Apparatedeckel, insbesondere Zellendeckel für Elektrolysezellen, mit einer verbesserten Wandauskleidung. Die vorgeschlagene, einfacher lösbare Auskleidung eignet sich besonders für den Einsatz an neuen oder gebrauchten Deckeln von Elektrolysezellen, die nach dem Amalgamverfahren arbeiten.The invention relates to corrosion-resistant apparatus covers, in particular cell covers for electrolytic cells, with an improved wall lining. The proposed Liner that is easier to remove is particularly suitable for use new or used lids of electrolytic cells made using the amalgam process work.
Für das Verkleiden von Elektrolysezellendeckeln aus Metall, die für den Einsatz im Amalgamverfahren geeignet sind, sind wenigstens drei verschiedene Verfahren bekannt:For the cladding of electrolytic cell covers made of metal, which are used in Amalgam processes are suitable, at least three different processes are known:
Das Aufbringen einer nicht lösbaren Verkleidung von Gummi auf einen konventionellen Stahldeckel oder die innere Verkleidung des Deckels mit nicht lösbaren Blechen aus Titan.The application of a non-removable covering of rubber on one conventional steel lid or the inner lining of the lid with non-removable Titanium sheets.
Aus EP-A 655 520 ist bereits ein Deckel für eine Elektrolysezelle bekannt, der mit einer Auskleidung aus Titan versehen ist.A cover for an electrolysis cell is already known from EP-A 655 520, which is lined with titanium.
Desweiteren werden auch Kunststoffolien zur Abdeckung der Zellen verwendet (sogenannte "Membrandeckel").Furthermore, plastic films are also used to cover the cells (so-called "Membrane cover").
Der Nachteil von gummierten Deckeln ist, daß sich an gummierten Deckeln durch Reaktion mit Chlor dioxin- und fliranhaltige Reaktionsprodukte bilden können. Ein weiterer Nachteil besteht in der aufwendigen Instandsetzung solcher Deckel. Soll ein gummierter Deckel neu beschichtet werden, so muß zunächst die Gummierung z.B. durch Kälte zum Sprödbruch gebracht werden und die am Deckel anhaftenden Gummireste müssen anschließend durch Abmeißeln entfernt werden.The disadvantage of rubberized lids is that rubberized lids get through Can form reaction with chlorine dioxin and fliran reaction products. On Another disadvantage is the costly repair of such covers. Should a rubberized cover must be re-coated, first the rubber coating e.g. brought to brittle fracture by cold and those adhering to the lid Rubber residues must then be removed by chiseling off.
Zellendeckel mit Titanauskleidung weisen folgende Nachteile auf. Die Verkleidung von Stahldeckeln mit Hilfe von Titanblechen ist vergleichsweise aufwendig und teuer wegen der vielen Schweißnähte an den Anodendurchführungen im Zellendeckel. Bei einer geringfügigen Beschädigung der Titanauskleidung gelangt feuchtes Chlor an den Zellenstahldeckel, wonach eine starke Korrosion des Stahlteiles einsetzt. Eine fachgerechte Reparaturschweißung an der Titanauskleidung ist wegen mangelhafter Gasbeschleierung des Spaltes zwischen Titanauskleidung und korrodiertem Stahldeckel praktisch nicht möglich.Cell covers with titanium lining have the following disadvantages. The costume of steel lids with the help of titanium sheets is comparatively complex and expensive because of the many welds on the anode feedthroughs in the cell cover. At If the titanium lining is slightly damaged, moist chlorine will reach the Cellular steel cover, after which strong corrosion of the steel part begins. A professional one Repair welding on the titanium lining is due to poor gas fogging the gap between the titanium lining and the corroded steel cover practically not possible.
Der Austausch eines Stahldeckels gegen einen "Membrandeckel" aus Kunststoff ist sehr kostspielig und praktisch schwer durchführbar, da u.a. die Konstruktion für die Stromzuführung geändert werden müßte. Überdies erweisen sich Membrandeckel als nachteilig, da sie die Möglichkeit begrenzen die Anoden vertikal zu verstellen.The exchange of a steel cover for a "membrane cover" is made of plastic very expensive and practically difficult to carry out, because the construction for the Power supply would have to be changed. In addition, membrane covers prove to be disadvantageous because they limit the possibility of vertically adjusting the anodes.
Der Erfindung liegt die Aufgabe zugrunde, einen Apparatedeckel mit korrosionsbeständiger Auskleidung zu schaffen, der die Nachteile der bekannten Konstruktionen nicht aufweist, wobei der Deckel mit einer leichter lösbaren Auskleidung aus Kunststoff oder Metall zu versehen ist. Insbesondere gilt es dabei Stromdurchführungen, beispielsweise bei der Verwendung als Elektrolysezellendeckel, zu berücksichtigen.The invention has for its object a device cover with corrosion-resistant Liner to create the disadvantages of the known constructions does not have, the lid with a more easily removable lining made of plastic or metal. In particular, current feedthroughs for example, when using it as an electrolytic cell cover.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf vorbereiteten d.h. zugeschnittenen, gebohrten oder angefasten Platten aus Kunststoff die Durchführungen für die Anoden angebracht werden, z.B. durch Schweißen. Nach dem Auflegen auf die Stahldeckel wird ein Herausrutschen der Anodenhülsen aus den Bohrungen durch geeignete Haltevorrichtungen verhindert, z.B. durch Haltebleche oder Verschraubungen.The object is achieved in that on prepared i.e. tailored, drilled or chamfered plastic plates the implementations for the Anodes are attached, e.g. by welding. After placing it on the steel cover the anode sleeves slip out of the holes by suitable Holding devices prevented, e.g. by holding plates or screw connections.
