的に塩素を製造することが望まれる。 When installing a hydrochloric acid electrolyzer at a site where chlorine is used and using the generated chlorine on the spot, the electrolytic voltage of hydrochloric acid should be kept as low as possible to ensure high current efficiency and effective use of the raw material, hydrochloric acid. It would be desirable to produce chlorine economically.

従つて、従来の塩酸電解槽では経済的に塩素を生
成することは難しかつた。 Generally, dilute hydrochloric acid after electrolysis is neutralized with an alkali and discarded, so from an economical point of view, it is necessary that the hydrochloric acid after electrolysis be as low in concentration as possible and as small in quantity as possible. However, when electrolysis is carried out to a point where the concentration of hydrochloric acid is extremely low in the non-diaphragm type or diaphragm type electrolyzers conventionally used for hydrochloric acid electrolysis, the electrolysis voltage becomes high and the current efficiency decreases due to the generation of oxygen. Therefore, the concentration of hydrochloric acid must be maintained above a certain level.
Therefore, it has been difficult to economically produce chlorine using conventional hydrochloric acid electrolyzers.

This invention was made in order to provide an electrolytic device for hydrochloric acid electrolysis that can be used in hydrochloric acid electrolysis.

る。 When hydrochloric acid is electrolyzed in the electrolytic device for hydrochloric acid electrolysis according to the present invention as shown in FIG. The aqueous hydrochloric acid solution after electrolysis is supplied to the interior of the adjacent unit anode chamber through a pipe 14. Similarly, the electrolyzed aqueous hydrochloric acid solution discharged from each unit anode chamber is sequentially supplied to the inside of the next unit anode chamber through pipes 15, 16, and 17, respectively. In each unit anode chamber, chlorine ions are oxidized to generate chlorine gas, and the generated chlorine gas is taken out from the gas outlet 21 of the anode chamber.

る。 Generally, a decrease in the concentration of an aqueous hydrochloric acid solution causes a decrease in current efficiency and an increase in electrolysis voltage, but according to the present invention, the concentration increases as water in the anolyte decreases, thereby maintaining a high current efficiency and lowering the electrolysis voltage. Hydrochloric acid, which is a raw material, can be used effectively while maintaining the same condition.

し処理費が低減される。 In addition, when hydrochloric acid is electrolyzed using the electrolysis device of the present invention, the low-concentration hydrochloric acid aqueous solution discharged from the last anode chamber is supplied to the cathode chamber in the electrolyzer, so that the low-concentration hydrochloric acid aqueous solution is conductive before being disposed of. It can be effectively used as a catholyte. In addition, the hydrochloric acid aqueous solution discharged from the anode chamber dissolves some of the chlorine generated at the anode and contains ClO - ions, so in order to dispose of the discharged liquid from the anode chamber, it is necessary to use ClO - In order to reduce ions to Cl - ions, a large amount of reducing agent such as sodium sulfite is required, whereas when using the electrolyzer of this invention, the liquid discharged from the anode chamber is supplied to the cathode chamber. Therefore, ClO - ions are reduced to Cl - ions by the cathodic reduction reaction, reducing the amount of expensive reducing agent required and reducing processing costs.
