Description
An apparatus or the electrolyeis of sea water or other saline especially for their Jean Pierre Sarrat Pierre DBS MIDI DBS SALINES invention relates to apparatus for the electrolysis saline especially of sea Although this he done for various the invention is primaril concerned with the electrolysis of sea water fo the destruction of present It is an object of the invention to provide an apparatus for the purpose which allows the periodic and automatic cleaning the electrodes from carbonates and mineral sediments or encrustations formed thereon even with high current densities and which causes a reduction in power consumption and which apparatus is simple and easy to requires a minimum of maintenance and operates at low cost and with a high degree of The invention consists in an apparatus for the continuous electrolysis of saline an electrolytic cell with inlet and outlet connections for the flow of the saline two sets of all of the same which the electrodes of each set are electrically connected in the electrodes of both have opposite and the electrodes of both sets are disposed in alternation and so as to form a plurality of parallel compartments through which the saline solution can the electrodes being held by a support head which is made an electrically insulating material inert to the saline solution and which closes the electrolytic cell in a and an inverter for reversing periodically the direction of flow of the electric current effecting the The electrodes may for of platinum alloy or the By an optional and preferred feature of the at least one consumable auxiliary electrode formed of copper may be incorporated in the circuit of the This auxiliary electrode is preferably connected directly to the positive pole of the supply circuit of the This auxiliary electrode in the electrolyte an oxidizing mixture of a halogen and copper example chlorine and in accordance with this invention has been found to be particularly effective against the development of The auxiliary electrode is connected to the supply circuit independently of the main Irrespective of the position of the inverter by which the main electrodes can alternately be to the positive and negative poles of the one group electrodes is always in opposite polarity with respect to the auxiliary The latter is so designed that the rate of liberation of copper ions can accurately be controlled so that the generation of free halogen is commensurate to the degree of contamination of the the copper is liberated intermittently and in quantities of the order of g 4 per cubic metre of The of switching the copper anode on and off controls the liberation halogen in the The fact that all the main electrodes are made from thejsame material possible periodic reversal of the direction of the The electrodes are preferably made from materials which are not readily This makes the operation of the cell simpler and cheaper and reduces maintenance In there is no preferential wear and tear of the plates of the one or the other after a long period of all electrodes have undergone uniform both sets of electrodes are replaced which can be done apparatus according to the invention is illustrated by way of example in the accompanying drawings 1 is a longitudinal sectional view of an electrolytic cell in accordance with the 2 is a transverse sectional view of the 3 circuit diagram of the The electrolytic cell illustrated in 1 and 2 comprises vessel 1 made from a material which is inert to sea water and to free synthetic The vessel may have any desired circular or The cell has inlet and outlet connections for the saline to be 5 Electrodes 3 are located within the They compose two sets of plates made from the material such as platinum or a platinum or the These are disposed in parallel to each other and to flow of the saline liquid through the and at short distances from each A copper electrode 4 is associated to the electrodes The plates of each set electrically connected in nodes and cathodes are arranged in as indicated in 2 by different hatchings The electrodes aremounted on a head made from an electrically insulating material inert to sea water and free synthetic The head forms a lid for the Each electrode plate is Inserted along the entire length of its upper part in a groove formed in the This arrangement makes the parallel disposition and a seat of the A metal bar 6 is provided as a common terminal for all plates of one of a bar 7 for the second and a 8 for the electrode all of them bein connectable to a source of The and electric insulation in the joints between the head and the electrodes are ensured by pouring a synthetic resin in the liquid state into the joints and making it set in A plugged drain 2 is provided at the bottom of the vess for the removal of solid deposite which are liable to accumulate in shows a simplified circuit diagram of the 6 The electrodes 3 are connected to a source of 12 via a reversing switch The circuit of the auxiliary anode 4 includes a contactor 13 connected to the positive pole of By way of the data of an electrolytic cell which has actually been constructed in accordance with the foregoing description are as maximum intensity amps u voltage 6 volts current density surface area of electrodes 200 nature of electrodes electrolytic graphite number of electrodes 10 dimensions of electrodes 195 100 x 10 mm space between electrodes 4 mm supplementary consumable anode copper The cell employed for the purpose of sterilizing 25 nrVhr of sea current was reversed at Chlorine was then produced a rate of 65 per cubic metre of sea In the operation of anapparatus according to the the desirable frequency the current reversals of dependent on the composition of the saline for with sea water a power consumption efficiency of at least can be by reversing the current at intervals of six hours whilst the current density can attain 500 amperes per 7 The gain in power consumption efficiency which is thus obtained is noteworthy since with known apparatus it frequently happens that an initial cienc of drops to and even less after a few even if the flow of current exceeds 1 This drop seems to follow from fouling of the The periodic reversal of the electrodes of the same material removes the limitations which have hitherto resulted from the of the electrodes and makes it possible to sterilize brines in a continuous process which destroys practically all the in the The liberation of 2 to grams of chlorine per cubic metre of water which is required in order to achieve this has no adverse effect on the electrodes and is able with a yield of up to g of chlorine per whilst the flow of current can be to 400 a A yield this ordermakes possible to process only a small fraction of the total output of the This processed which is thus strongly is then mixed with the main flow brine in order to produce in the latter a chlorine level of 2 to 3 grams per cubic metre of 8
