Definitions

  • the invention relates to a device for electrolysing a chloride, in which several electrolytic cells consisting of electrodes and a diaphragm are electrically connected in series, whereby each cell is provided with a supply line and a discharge line for electrolyte, and a discharge line for the gas developed, said cells being surrounded by an encasing having two plates on end, and whereby a fluid jacket, provided with a supply line and a discharge line for fluid, is disposed between the encasing and the outside of the cell frames.
  • This seal is in particular important because the electrolytic process leads to chemically agrressive substances being formed, which are highly corrosive with respect to the area around the cell.
  • Such seals make the electrolytic cells costly, and their production is only possible by using labour-intensive methods. 'Furthermore it has become apparent that the seals used up to now develop leakages, especially after some time has lapsed. Furthermore, as a result of different seals being used, it is problematic or costly to secure the electrodes flat in the frames.
  • Another drawback of the seals to be used is that they are often the determining factor with regard to the distance between the electrodes; a larger distance between the electrodes often results in a reduced current efficiency.
  • a device as mentioned in the preamble, and said device is characterized in that said fluid is a liquid, and that said de-aeration tubes for separating and discharging chlorine gas and hydrogen are disposed in the fluid jacket, and that the electrodes are combined to form bi-­polar electrodes.
  • a fluid jacket is provided within the encasing of the device, around the system of the cell frames having bi-polar electrodes, said fluid preferably being water, so that a possible leak from the electrolytic cells is allowable, because any fluid that leaks out is collected in the water jacket, which is periodically or continuously changed. A slight in-leakage of water is acceptable thereby.
  • the electrolyte and the gas which has formed are separated, so that hydrogen and chlorine gas from said de-aeration tubes can readily be recovered.
  • the construction of the de-­aeration tubes and the supply line for electrolyte and gas to said de-­aeration tubes will be explained in more detail hereinafter. Although the following part of the present description relates to such a preferred electrolytic process for preparing chlorine gas, it will be apparent that also other electrolytic processes may be carried out in such a device.
  • the development of chlorine gas in particular for purifying swimming water in swimming pools is receiving a lot of attention, because when the chlorine gas which has been developed is used, it is not necessary to use chlorine bleaching lye or the like.
  • the device according to the invention can also be used, however, to prevent the occurrence of algal growth in cooling towers, to pasteurize milk or icecream, which may also be done by means of UV-light, and in general in those places where germs and the like are killed.
  • bi-polar electrodes which are secured between the cell frames.
  • Said bi-polar electrodes according to the invention consist of an anode plate, a cathode plate, and a centre wall located therebetween. Ridges are pressed in the electrode plates, which bottom sides form a welded joint between the electrodes and the centre plate.
  • the anode weld and the cathode weld lie in one plane thereby, extending perpendicularly to the centre wall, so that no weldings stresses are set up, which might cause the plates to become warped.
  • Bi-polar electrodes in general are known from Dutch Patent Application 7808691, which discloses bi-polar electrodes provided with spacers between the anode plate and the cathode plate. From said Dutch Patent Application it appears how important it is that a constant distance is maintained between the anode plate and the cathode plate and the centre wall, and that costly measures must be taken with the known bi-polar electrodes in order to obtain properly operating bi-polar electrodes. According to the invention it has now become possible to obtain inexpensive constructions for bi-polar electrodes, whereby it has been ensured that the bi-polar electrodes are permanently flat and that the distance between the anode plate and the cathode plate of the bi-polar electrode is as small as possible.
  • FIG 1 a sectional view of the device according to the invention is shown, said device consisting of an encasing having two plates 1 and 2 on end, said encasing being provided with a current supply lead 12 and a current discharge lead 11, between which there are provided several electrolytic cells, one cell consisting of a bi-polar electrode 6 being illustrated in more detail.
  • Said bi-polar electrode 6, illustrated in detail in Figure 4 consists of a cathode 4 and an anode 3, both being welded on a centre plate 5. Both electrodes 3 and 4 have been provided with ridges, indicated by 18, which ridges have been welded at the lower side in the centre plate 5.
  • the electrolytic cells are provided with a supply line for electrolyte 9 and a discharge line 10 for said electrolyte, said discharge line 10 opening into a riser pipe 13, which opens into the de-aerator 8.
  • the electrolyte which is discharged at 10 and 13 comprises the gas formed in the electrolytic process, which gas may e.g. be hydrogen or chlorine released from the fluid carried along in the de-aerator 8.
  • a foamy product is therefore introduced into the de-aerator via the conduit 13, which product is separated into a fluid and a gas in the de-aerator. This is explained in more detail with reference to Figure 3.
  • the bi-polar electrodes are encased in seals.
  • a greater tolerance is possible when the electrodes are placed between frames, because any leaking electrolyte is collected in the water jacket 7a, 7b and 7c.
  • the device according to the invention is at its upper side provided with a water dosaging device 14 and with a water discharge line 15, which opens into the electrolyte that is supplied to the cell via the conduit 16.
  • the water which functions to catch any leaking electrolyte, can be used in the cell as the fluid to be electrolysed.
  • the encasing may be provided with seals which do not have to meet the same stringent demands as the known cells mentioned above. Said seals are used at the joint between the horizontal encasing parts and the plates on end. For this purpose a simple rubber seal may be used, as is indicated at 17 in the drawing.
  • FIG 2 is a diagrammatic perspective view of the construction of the device according to the invention, the core of the electrolytic cell being formed by the bi-polar electrode 6, which consists of a centre plate 5 on which the cathode 4 and the anode 3 are provided.
  • the cathode 4 is shown to have ridges 18, the bottom sides of the ridges are welded on the centre plate 5.
  • the bi-polar electrodes are secured between the cell frames.
  • the bi-polar electrode 6 is secured between the cell frames 20 and 21.
  • the various bi-polar electrodes are mutually separated by means of the diaphragms 22 and 22a.
  • the cathode and the anode are preferably made of a gauze or a perforated metal plate.
  • the openings 24 and 25 open into the discharge tubes 13 and 13a for the electrolyte, said discharge lines from the conduits 13 and 13a in turn opening into the de-aeration tubes 8 and 8a.
  • a de-aerator is as such known from EP-A- 43,945.
  • chlorine gas can be efficiently obtained by means of an electrolytic process, whereby the electrolytic cell has been improved considerably with respect to the known cells, to the effect that no costly seals need to be used, and that the bi-polar electrode can be formed in an efficient manner.
