Description
Gegenstand der Erfindung ist ein Verfahren zum Korrosionsschutz im Betonboden elektrolytischer Zellen als Verstärkung eingebetteter Metallteile. Es findet beispielsweise Anwendung bei der Elektrolyse von Alkalichloridlösungen zur Herstellung von Chlor und Alkalihydroxyd. Durch die vorliegende Erfindung werden die Zellenteile vor Reißen oder Brechen während der Verwendung geschützt.The invention relates to a method for corrosion protection in the concrete floor of electrolytic cells as reinforcement of embedded metal parts. It is used, for example, in electrolysis of alkali chloride solutions for the production of chlorine and alkali hydroxide. Through the present invention the cell parts are protected from cracking or breaking during use.
Hersteller für elektrolytische Zellen zur Gewinnung von Chlor kämpfen seit Jahren mit der Schwierigkeit, daß die Böden der Zellen, die gewöhnlich aus Stahlbeton hergestellt sind, nach einer gewissen Verwendungszeit reißen und ersetzt werden müssen.Manufacturers of electrolytic cells for the production of chlorine have been struggling for years with the difficulty of that the floors of the cells, which are usually made of reinforced concrete, after a certain period of use tear and need to be replaced.
Es wurde nun ein Verfahren gefunden, durch das ein Brechen oder eine Zersetzung des Betonbodens verhindert oder wesentlich herabgesetzt wird. Der stahlverstärkte Betonboden einer elektrolytischen Zelle kann dadurch geschützt werden, daß man das verstärkende Metall mit dem negativen Pol eines Elektrolysestromkreises verbindet. So kann beispielsweise das eine Ende eines Leiters, z. B. eines Kupferdrahtes an dem verstärkenden Netzwerk aus " Metall innerhalb des Betonbodens und das andere Ende des Leiters an der Kathode der Zelle befestigt werden.A method has now been found by which the breaking or decomposition of the concrete floor prevented or significantly reduced. The steel reinforced concrete floor of an electrolytic Cell can be protected by connecting the reinforcing metal to the negative pole of a Electrolysis circuit connects. For example, one end of a conductor, e.g. B. one Copper wire to the reinforcing network of "metal inside the concrete floor and the other End of the conductor to be attached to the cathode of the cell.
Auf diese Art wird ein Stromweg von geringem Widerstand von der Kathode zu dem Stahl geschaffen, wodurch das Metallnetzwerk und die Kathode im wesentlichen an der gleichen Spannung liegen. Es kann aber auch eine von der Elektrolysestromquelle unabhängige Hilfsstromquelle verwendet werden.In this way a low resistance current path is created from the cathode to the steel, whereby the metal network and the cathode are at essentially the same voltage. It however, an auxiliary power source independent of the electrolysis power source can also be used.
Nach dem vorliegenden Verfahren wird die während der Verwendung der elektrolytischen Zelle stattfindende
schädliche und kostspielige Zersetzung der Betonboden wesentlich verringert. Die zur Erzielung
dieses Schutzes erforderliche Leistung ist sehr gering. Sie beträgt im allgemeinen weniger als 0,7 A pro
Zelle. Es liegt daher auf der Hand, daß der Schutz unter sehr geringem Kostenaufwand erzielt wird und
Verfahren zum Korrosionsschutz
elektrolytischer ZellenAccording to the present method, the harmful and costly degradation of concrete floors that occurs during use of the electrolytic cell is substantially reduced. The power required to achieve this protection is very poor. It is generally less than 0.7 A per cell. It is therefore obvious that protection is achieved at very little cost and methods of corrosion protection
