Description
KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
In dem Patent 274964 ist ein Verfahren und eine Vorrichtung zur Elektrolyse von Halogenalkalien gemäß dem horizontalen Diaphragmenprinzip beschrieben, bei dem für eine Regelung der Filtriergeschwindigkeit zur Erreichung einer bestimmten Laugenkonzentration der hydrostatische Druck des über dem Diaphragma stehenden Elektrolyten durch Veränderung des Druckes des sich im Kathodenraum bildenden Gases (Wasserstoff) teilweise aufgehoben wird. Die Veränderlichkeit des Gegendruckes ist dabei durch eine in dem Abzugrohr des Kathodenraumes angeordnete, einstellbare Ventilvorrichtung erzielt.In the patent 274964 is a method and an apparatus for the electrolysis of Halogen alkalis are described according to the horizontal diaphragm principle, in which for a regulation of the filtration speed to achieve a certain concentration of caustic solution the hydrostatic pressure of the electrolyte above the diaphragm by changing the pressure in the cathode compartment forming gas (hydrogen) is partially canceled. The variability of the back pressure is due to one in the Achieved adjustable valve device arranged exhaust pipe of the cathode chamber.
Gemäß der Erfindung erfolgt eine teilweise Aufhebung des hydrostatischen Druckes des Elektrolyten durch Regelung des Unterdruckes, auf dem das sich im Anodenraum entwickelnde Chlorgas gehalten wird.According to the invention there is a partial cancellation of the hydrostatic pressure of the Electrolytes by regulating the negative pressure at which the developing in the anode compartment Chlorine gas is held.
Das Chlorgas wurde auch bis "jetzt aus dem Anodenraum abgesaugt. Dies geschieht aber nur zum Zweck, ein Austreten des Chlorgases aus dem Behälter an undichten Stellen und dadurch einerseits eine Verunreinigung der Atmosphäre des Arbeitsraumes und andererseits Chlorgasverluste zu vermeiden. Daher beträgt das Vakuum nur etwa 10 mm Wassersäule. Durch Erhöhung dieses Unterdruckes kann nun der hydrostatische Druck des über dem Diaphragma stehenden Elektrolyten derart vermindert werden, daß dadurch eine bestimmte Filtriergeschwindigkeit und dementsprechend die gewünschte Laugenkonzentration erreicht wird.Up until now, the chlorine gas has also been sucked out of the anode compartment. But this is what happens only for the purpose of leakage of the chlorine gas from the container at leaks and thereby on the one hand a contamination of the atmosphere of the work area and on the other hand To avoid chlorine gas losses. Therefore the vacuum is only about 10 mm water column. By increasing this negative pressure, the hydrostatic pressure of the electrolyte above the diaphragm can be increased in this way be reduced, that thereby a certain filtering speed and accordingly the desired alkali concentration is achieved.
Um nun dauernd gleiche Laugen erhalten zu können, kann man die Absaugvorrichtung für das Chlorgas mit einem einstellbaren Regler versehen. Durch diesen ist es ermöglicht, die Filtriergeschwindigkeit während des Prozesses genau einzustellen, auch wenn das Diaphragmafilter durch sich ablagernde Verunreinigungen des Salzes weniger durchlässig wird.In order to be able to obtain the same alkaline solution all the time, the suction device can be used equipped with an adjustable regulator for the chlorine gas. This makes it possible precisely adjust the filtration speed during the process, even if that Diaphragm filter less permeable due to the accumulation of contaminants in the salt will.
