Electrolyzer apparatus

An electrolyzer apparatus in which an electrolysis reaction is effected with an anode and a cathode both being submerged in an electrolytic solution containing chlorite and a chlorine dioxide gas is generated from the anode side;

• wherein an anode tank having the anode and a cathode tank having the cathode are provided separately from each other;
• the anode tank includes a feed opening for feeding an amount of electrolytic solution into the tank, an anode aeration device for feeding aeration air to the fed electrolytic solution, and a gas extraction pipe for guiding gas generated from the anode tank to outside of the tank;
• a communication pipe having one end thereof connected to a lower portion of the anode tank and the other end thereof connected to a lower portion of the cathode tank is provided for generating a flow of electrolytic solution from the anode tank to the cathode tank;
• via the electrolytic solution in the communication pipe, electric conduction is established between the anode and the cathode;
• an amount of chlorine dioxide gas generated by an electrolysis reaction inside the anode tank is discharged to the outside of the anode tank via the gas extraction pipe together with the aeration air and the electrolytic solution introduced into the cathode tank is discharged continuously;
• a gas collection pipe having one end thereof connected to an upper portion of the anode tank and the other end thereof connected to an upper portion of the cathode tank;
• a cathode aeration device for feeding aeration air to the fed electrolytic solution present in the cathode tank;
• and
• an amount of chlorine dioxide dissolved and remaining in the electrolytic solution in the cathode tank, together with the aeration air, is allowed to flow into the anode tank via the gas collection pipe to merge the fed amount of chlorine dioxide into an amount of chlorine dioxide gas generated in the anode tank, and is extracted via the gas extraction pipe to the outside of the anode tank.
