る。(Prior Art) Various types of ion-exchange membrane salt electrolyzers have been proposed, and many single-pole filter press type devices have been proposed in which the electrolytic cell can be easily installed. (For example, JP-A-53-108899, JP-A-54-
152677, 56-142880, 57-16185) However, all of these systems have a considerable distance between the electrodes and use ion exchange membranes, making them less efficient in terms of power consumption.

を完成した。(Means for Solving the Problems) The present inventors have developed a monopolar filter press type that can watertightly sandwich an ion exchange membrane between adjacent electrode bodies and bring both electrodes as close as possible to the ion exchange membrane. As a result of intensive study on the electrolyzer, we found that the mesh-type electrolytic electrode in the electrode body was bulged out beyond the surface of the frame to which the mesh was attached, and the desired thickness was created between the electrode body and the ion exchange membrane. They discovered that the problem could be solved by sandwiching the gasket, and completed the present invention.

The body is arranged repeatedly through an ion exchange membrane, and the frame has a gas-liquid hole for the cathode and a gas-liquid hole for the anode on the upper side, and a hole for supplying dilute caustic soda and a hole for supplying salt water on the lower side. The frame-shaped frame, which has a communication hole and constitutes the anode body, has a communication hole that connects the central opening and the anode gas-liquid communication hole and the salt water supply communication hole, and constitutes the cathode body. is a mesh type electrolyzer that constitutes an electrode body in a monopolar filter press type ion-exchange membrane salt electrolyzer that has a communication hole connecting the central opening and the gas-liquid communication hole for the cathode and the communication hole for dilute caustic soda supply. Substantially the entire surface of the electrode is uniformly bulged outward from the outer surface of the frame, and there is a gap between the electrode body and the ion exchange membrane that is approximately the same shape as the frame and is higher than the height of the bulge of the electrode. The ion exchange membrane method salt electrolyzer is equipped with a gasket having a thickness of

It is.

つけられている。 A 1 and A 2 are frame-shaped frames of the anode body E A , to which the mesh-type electrolytic electrode A is attached outwardly from the outer surface of the frame-shaped frame and almost uniformly bulges out. .

いる。 The frame-shaped frames A 1 and A 2 are made in a symmetrical shape and arranged symmetrically so that the mesh-type electrolytic electrodes face outward, and the frame-shaped frames have an opening 8 in the center. The upper side has a gas-liquid passage hole 3 for the cathode and the gas-liquid passage hole 2 for the anode, and the lower side has a passage hole 5 for supplying dilute caustic soda and a passage hole 4 for supplying salt water. The central opening 8 has communication holes 6 and 7 communicating with the anode gas-liquid communication hole 2 and the salt water supply communication hole 4.

て１〜10mm程度の高さが好ましい。 The mesh-type electrolytic electrode A may be made of a conventionally used material and has a mesh size, but it is preferable that the mesh size is small because the electrodes can be brought as close together as possible and the current density is made more uniform. In addition, although the height of the bulge is not particularly limited, if it is too low, the gasket Pm will become thin and it will be difficult to manufacture it with high precision.Therefore, it will be difficult to make the distance between the electrodes uniform and as close as possible. This is undesirable because the proportion of the gasket portion in the entire electrolytic cell increases, making it soft and reducing accuracy. Therefore, the height is preferably about 1 to 10 mm.

However, the overall shape and size of the gasket
It is almost the same as P A , and in addition to the central opening 9, similar through holes 2, 3, 4, and 5 are formed on the upper and lower sides. However, the thickness of the mesh-type electrolytic electrode A
The thickness is selected in accordance with the height of the bulge, that is, in consideration of the thickness that allows the anode A and the cathode C to be brought as close as possible, and the change in thickness due to tightening of the electrode body when the electrolytic cell 1 is assembled. Therefore, a thickness greater than the bulge height is selected.

The inner surface of each hole of each electrode body must be resistant to the respective gas or liquid. Methods for imparting this resistance are not particularly limited, but may include painting, plating, inserting a sleeve that fits into each hole, and attaching both ends of the sleeve to gaskets such as Pc, Pa, and Pm. A method of making watertight contact is possible.
Furthermore, gaskets in which the sleeve is integrally formed with the gasket are also preferably used.

も長くなる効果を有する。(Operations and Effects) The present invention has the above-mentioned structure, particularly the mesh-type electrode for electrolysis, which bulges out from the outer surface of the frame-like frame for attaching it, so that the thickness of the gasket between it and the ion exchange membrane can be adjusted. The inter-electrode distance can be adjusted easily and precisely by using a chisel. An even greater effect is that in the case of the conventional method that does not bulge, the ion exchange membrane must be pushed toward the electrode using another support, etc., which places undue stress on the thin ion exchange membrane. However, in the device according to the present invention, no excessive force is applied to the ion exchange membrane, which has the effect of extending its life.
