选取利用太阳能获取电能,进行水溶液电解再生纯铁的实验室研究。利用已有的一套太阳能光伏发电装置作为电源,设计、选取电解部分的试验装置,安装进行预试验。在前阶段试验的基础上,结合各项工艺参数的影响条件,确定试验的指标和影响因素。对试验结果进行初步分析,结合操作方便和经济等方面考虑,确定各因素水平,即FeCl2.4H2O:300 g/L;NaCl:80 g/L;温度:75℃;pH:2.0;极距:40 mm;电流密度:8.0 A/dm2。对比这个试验阶段其它工况,在这样的工况下,电解的电流效率相对较高,且电解铁的形貌相对较好。
Select the use of solar energy for access to electricity, electrolytic regeneration of pure iron laboratory research. Using the existing set of solar photovoltaic power generation device as a power source, a test device for the electrolysis part is designed and selected, and the pre-test is carried out. On the basis of the previous stage tests, combined with the influence of various process parameters, the test indicators and influencing factors were determined. The preliminary analysis of the test results, combined with convenient operation and economic considerations, to determine the level of each factor, namely FeCl2.4H2O: 300 g / L; NaCl: 80 g / L; temperature: 75 ℃; pH: 40 mm; current density: 8.0 A / dm2. In contrast to other operating conditions in this experimental phase, the electrolysis current efficiency is relatively high under such conditions, and the morphology of the electrolytic iron is relatively good.
