| 摘要 |
The invention pertains to a method of measuring and/or controlling the electrolytic bath liquid level in an electrolysis cell for the generation of fluorine gas having an anode chamber and a cathode chamber separated from each other by a partition wall for generating fluorine gas by electrolyzing an electrolytic bath (electrolyte) comprising a hydrogen fluoride-containing mixed molten salt of an HF adduct of KF, wherein the method comprises the steps of (a) detecting the pressure in at least one of the anode chamber and the cathode chamber during generation of fluorine gas by pressure sensing means comprising a tube (liquid level sensing tube) reaching (submersing) into the electrolytic bath (electrolyte), and, preferably, (b) supplying through the tube of the pressure sensing means an effective amount of hydrogen fluoride to thereby remove and/or prevent plugging caused by potentially crystallized HF adduct of KF in the tube of the pressure sensing means at any time and/or during measuring and/or controlling the electrolytic bath (electrolyte) liquid level in the anode chamber and/or cathode chamber. |
