[Problem] To provide a device for producing chlorine dioxide in which the amount of chlorine dioxide generated can be accurately controlled. [Solution] Provided is a device for producing chlorine dioxide gas, the device being provided with an electrolytic chamber, a liquid surface level measurement chamber, and a bubbling gas feed device. The electrolytic chamber and the liquid surface level measurement chamber each contain an electrolytic solution and a gas. The electrolytic solution contains a chlorite aqueous solution. The electrolytic chamber and the liquid surface level measurement chamber are connected to each other through a gas pipe located above the respective liquid surfaces and through an electrolytic solution pipe located below the respective liquid surfaces so that the height of the electrolytic solution contained in both chambers is essentially equal. The electrolytic chamber is provided with a negative electrode and a positive electrode. The negative electrode and the positive electrode are fixed to a spacer. The electrolytic chamber is provided with a bubbling gas feed unit, located in the electrolytic solution, for feeding a gas by bubbling from the exterior of the electrolytic chamber into the electrolytic solution in the electrolytic chamber. The gas feed unit is connected through a pipe to the bubbling gas feed device arranged outside the electrolytic chamber. The liquid surface level measurement chamber has a means for measuring the liquid surface level. |
