Diaphragm-free electrolytic manganese metal method

According to the method, a selective electro-catalysis oxygen evolution anode is adopted to replace a traditional lead alloy anode, dilution of anode Mn < 2 + > is inhibited, generation of anode mud is reduced, meanwhile, an alkali liquor pipeline for maintaining the pH value of electrolyte to be stable is additionally arranged, and therefore the electrolytic manganese metal without the diaphragm is obtained. A false bottom, a diaphragm frame, a diaphragm and an anolyte overflow channel in a traditional electrolytic cell are removed, the structure of the electrolytic cell is simplified, the continuity of the production process is improved, the cell voltage and energy consumption in the electrolytic process can be reduced, and the production cost of an enterprise is greatly reduced. 本发明公开了一种无隔膜电解金属锰的方法，通过采用选择性电催化析氧阳极代替传统铅合金阳极，抑制阳极Mn2+的贫化，减少阳极泥的生成，同时加装维持电解液pH值稳定的碱液管道，进而去掉了传统电解槽中的假底、隔膜框、隔膜以及阳极液溢流通道，简化了电解槽的结构，提高了生产过程的连续性，并且能够使电解过程槽电压以及能耗降低，大幅度降低了企业的生产成本。
