Aqueous solution production method containing chlorine dioxide and steam generator

Japanese Patent JP6359344

B2

PROBLEM TO BE SOLVED: To provide a method of capable of quickly producing a uniform halogen dioxide aqueous solution, preferably chlorous acid, from a halogen dioxide salt aqueous solution, preferably chlorite, and capable of using steam converted from the halogen dioxide aqueous solution by a pump of smaller output.SOLUTION: In a method of producing an aqueous solution containing halogen dioxide, an aqueous solution containing a halogen dioxide salt, preferably chlorite, is poured into a container 3 having electrodes 5, 6 from a storage tank 1 by a pump 2, an electric current is made to flow between the electrodes from an AC power supply device 4 to convert the halogen dioxide salt into a halogen dioxide, and an aqueous solution containing the halogen dioxide is made to flow out from a nozzle 7. The supplied aqueous solution contains a halogen dioxide salt in a concentration of at least 1 ppm. The produced aqueous solution contains a halogen dioxide in a concentration of 0.5-5,000 ppm, preferably 1-500 ppm. Two or three electrodes are provided in the container for increasing pressure by steam generation, to which 100-230 V single-phase or three-phase alternating current is supplied, and a halogen dioxide-containing aqueous solution is produced.
