APPARATUS FOR CONTINUOUS ELECTROLYSIS OF AQUEOUS SOLUTIONS Specification of Letters Patent.
Patented Nov. 29, 1910.
Application filed November 17, 1909. Serial No. 528,598.
To all whom it may concern:
Be it known that We, -knnmrr lin'rz-sorr, electrical engineer, a subject of the King of Saxony, and resident of Triberg, Grand- Duchy of Baden, Germany, and EWALD STEINBUCH, electrical engineer, a citizen of the Swiss Republic, and resident of Monthey, Canton of Valais, Switzerland, have invented new and useful Improvements in Apparatus for Continuous Electrol sis of Aqueous Solutions, of which the to lowing is. a full, clear, and exact specificatio In our application for Letters Patent No. 528572 we have described a process for the electrolysis of aqueous solutions, wherein the electrolyte is caused to flow from an upper to a lower electrode and is enriched again by solid salt.between the two electrodes,
after havin been impoverished at the upper electro e, in order that as many ions as possible of the initial electrolyte may travel in the op osite direction to the migrating ions ten ing to diminish the yield.
The object of the present invention is now an apparatus to carry out the said process for the electrolysis of aqueous solutions.
In this apparatus a support for solid salt is arranged between the two superposed electrodes and is preferably combined with a device forming a trap for the gases generated at the lower electrode.
In the accompanying drawing Figure 1 shows in vertical section the preferred construction of this apparatus and Fig: '2 represents also in vertical section a somewhat modified construction of the same.
In Fig. 1, a is the anode, b the cathode which is electrically connected with the iron container 0. 03 represents two partitions of non-conducting material separating the anode compartment from the cathode compartment and between these partitions there are stretched, on the one hand, a porous fabric J6 which carries the solid salt f supplied through the pipes 91 and, on the other hand, a porous fabric 9 closing the bottomof the anode compartment and conducted over nonconducting rods it giving the said fabric 9 a zigzag form, so that this latter may serve as a as trap; j is the pipe through. which the sa t solution is fed to the apparatus and i is the overflow through which the formed lye is discharged.
Assuming the apparatus is used for the electrolysis of a solution of common salt, in order to produce soda lye, eration will be the following: The salt solution flowing into the electrolytic cell through j, after it has become artially impoverlshed at the anode, ows partly through the salt f and partly over this salt, and there is formed over the fabric 9 a layer of concentrated salt solution which passes through the fabric 9 to the cathode compartment and thus prevents migration of the ions formed at the cathode into the anode compartment. The gas (hydrogen) generated at the cathode is caught by the corrugations of the fabric g and led away laterally. As the fabric 9 is situated .at a certain the mode of openriched with salt below the anode has to traverse a distance of some centimeters before it arrives at the concentrated l e situated directly below the gas trap abric g and this long path it catches the OH- ions migrating uwardly from the cathode b.
In the modlfie construction of Fig, 2, the
solid salt f is supplied directly on the porous fabric Z stretched in zlgzag form and closing the bottom of the anode compartment, the
said fabric serving consequently simultana ously as salt carrier and as gas trap.
