Embodiment 1
[0007] The saturated solution of raw material sodium chlorate is 15 tons, the pH value is controlled to be 6, and the electrolysis temperature is controlled to be 55°C, the ceramic-based lead dioxide electrode is used as the anode, the stainless steel electrode is used as the cathode, and six electrolytic cells are connected in series to form a Group, the electrolyzers are arranged in steps according to the potential difference, the tank pressure is 5 volts, the electrolyte flows from the high position tank to the highest position electrolyzer, overflows into the next position electrolyzer to continue electrolysis, and then overflows into the next electrolyzer, The conversion rate of chlorate at the end of electrolysis is controlled at 70%, and the electrolysis time is 30 hours. The electrolysis completed solution is reacted with potassium chlorate to produce potassium perchlorate, and the mother liquor is returned to the electrolysis process for further electrolysis after treat...
Embodiment 2
[0009] The saturated solution of raw material sodium chlorate is 12 tons, the pH value is controlled to be 7, and the electrolysis temperature is controlled to be 65°C, the ceramic-based lead dioxide electrode is used as the anode, the stainless steel electrode is used as the cathode, and five electrolytic cells are connected to form a One group, the electrolyzers are arranged in steps according to the potential difference, the tank pressure is 4 volts, the electrolyte flows from the high position tank to the highest position electrolyzer, overflows into the next position electrolyzer to continue electrolysis, and then overflows into the next electrolyzer , control the conversion rate of chlorate at the end of the electrolysis at 72%, and the electrolysis time is 25 hours. The electrolysis complete solution is reacted with potassium chlorate to produce potassium perchlorate, and the mother liquor is returned to the electrolysis process for electrolysis after treatment. In this ...
