如き電解槽において.電解時に電極で発生する気泡の影
響を低下させることができる特殊な電極室を提供する。For example, to explain the electrolysis of an aqueous sodium chloride solution, when an aqueous sodium chloride solution is supplied to an anode chamber, sodium ions, water, and in some cases chlorine ions are transferred to the cathode chamber through a diaphragm. At the anode, chlorine ions are oxidized,
Chlorine gas bubbles rise in the anode chamber liquid and are extracted from the gas outlet. Further, hydrogen ions are reduced at the cathode, and hydrogen gas rises in the cathode chamber liquid as bubbles and is extracted from the gas outlet. Furthermore, the cathode chamber solution is taken out as caustic soda. In this case, if a cation exchange membrane is used as the diaphragm, chlorine ions will not substantially migrate to the cathode chamber.
Since water does not substantially migrate to the cathode chamber except for hydration water of sodium ions, there is an advantage that caustic soda of high purity and high concentration can be obtained. Further, since ion exchange membranes are generally strong and thin, they have the advantage that the distance between the negative and positive electrodes can be reduced, and their smooth surfaces prevent air bubbles from becoming stagnant. Even in the present invention described below, the distance between the diaphragm and the front surface of the electrode (the surface facing the diaphragm) is narrow, and moreover, during use, it is always kept at a predetermined distance, e.g.
Since it is preferable to keep the thickness between 5 mm and 5 mm, it is recommended to use an ion exchange membrane as the diaphragm. The present invention provides an electrolytic cell as described above. To provide a special electrode chamber capable of reducing the influence of bubbles generated at the electrode during electrolysis.

ブや補強リブに付設することもできる。In the figure, 1 is the anode. 2 is a cathode, 3 is a diaphragm such as an ion exchange membrane. 4 is the back wall of the anode chamber. 5 is the back wall of the cathode chamber. 6 is the anode chamber frame, and 7 is the cathode chamber frame. An anode chamber is constituted by an anode 1, a back wall 4, and an anode chamber frame 6. The cathode 2, the back wall 5, and the cathode chamber frame 7 constitute a cathode chamber. Also, 8 supports the anode. These are conductive ribs that supply electricity to this. Similarly, 9 is a conductive rib on the cathode side. Also, 10 is punching. When electrolyzing, for example, a sodium chloride aqueous solution using this electrolytic cell, salt water is supplied from the liquid supply port 20, and waste salt water and chlorine are taken out from the liquid and gas extraction port 21. On the other hand, from the liquid supply port 22 depending on the case. Water or dilute alkali is supplied, the concentration of caustic soda produced is adjusted, and caustic soda and hydrogen are taken out from the extraction port 23. Further, the electrode chamber liquid can be circulated if necessary. Furthermore, the supply port,
Extraction ports (appropriate number can be provided as needed.
One of the features of the present invention is that the electrode chamber is The reason for this is that a guide plate 11 having an upward slope toward the porous electrode 2 is attached.
By installing the guide plate in this way, the circulating fluid or the fluid supplied to the lower part for concentration adjustment and/or the fluid that permeates through the diaphragm can be controlled. It rises, encompassing the air bubbles generated at the electrode. The action of the guide plate changes the direction of the flow toward the front of the electrode, and the flow velocity increases near the tip of the guide plate.
The liquid flows as if washing the porous surface of the electrode as shown by the arrow.
As a result, air bubbles remaining on the electrode surface are washed away. A large amount of liquid passes through the passage per unit time, and together with the effect of lowering the bubble density, the negative effects of bubbles are significantly reduced. FIG. 2 is a cross-sectional view (only the cathode chamber portion) taken in a direction perpendicular to FIG. 1, and is an explanatory diagram for easily understanding the position of the guide plate 11. In FIG. 2 and the following drawings, the same reference numerals are used for the same parts as in FIG. 1. FIG. 2 shows that the guide plate 11 is provided over almost the entire width of the electrode chamber.
Examples of methods of fixing the guide plate in FIG. 2 include a method of fixing it to the back wall 5 as shown by arrow A, a method of fixing it to the side wall of the electrode chamber frame 7 as shown by the arrow opening, and a method of fixing it to the side wall of the electrode chamber frame 7 as shown in this figure. When the ribs are provided in the vertical direction, they can be attached to conductive ribs or reinforcing ribs as shown by arrow C.

両電極室に対しても付設し得るものである。The partition plate 12 does not span the entire height of the electrode chamber, and has appropriate gaps at its upper and lower parts. For this reason. The electrode chamber liquid rises near the electrode 2 as shown by the arrow, and descends by the downcomer 1. It circulates within the electrode chamber so that it is guided toward the electrode side at the bottom. Such an embodiment is also a preferred example of the present invention. In the above Figures 1 to 3, we have mainly shown an example in which a guide plate is attached to the cathode chamber, but of course, in the case of electrolysis that generates bubbles, it may also be used for the anode chamber or both the cathode chamber and the anode chamber. It can also be attached to the electrode chamber.

第1図に示す如き電解槽を用いる。In this example. The cathode chamber frame 7 and the anode chamber frame 6 are integrated, and the back walls 4 and 5 are the same partition wall (however, in FIG. 4, the anode chamber side member is represented by 46, and the cathode chamber side member is represented by 5).
It's getting more familiar. Usually, in an electrolytic cell for an aqueous alkali metal salt solution, the anode chamber side member is made of dust such as titanium or rubber lining, and the cathode chamber side member is made of mild steel, but is not limited to these members. Further, in FIG. 4, 13 is a support member that supports the conductive ribs, and 14 electrically connects the anode and cathode by means of penetrating the inside of the partition wall. Excellent effects can be expected by using a clad plate as this connection means. Example 1 An electrolytic cell as shown in FIG. 1 is used.
