摘要
简述了采用氧阴极代替铁阴极,以空气作退极化剂的电化生产氯酸盐平板压滤机式复极电解槽的结构与性能.当电极工作电流密度为100mA/cm^2时,电解槽的平均单池电压在2.000～2.200V之间;电解液中无需添加Na_2Cr_2O_7,电流效率可达90±2%,生产每吨NaClO_3的直流电耗为3700±100kw·h.电解槽运行稳定,单池电压分布均匀.
This paper briefly describes the structure and performance of a special bipolar filter press -type chlorate cell. The cathode is oxygen diffusion electrode, which replaces the current iron cathode, and air acts as de - polarizer. When the cell is operated at the 100 mA/cm2current density, the average single cell voltage is between 2. 000 and 2. 200V. The current efficiency can reach 90 ± 2% with the absence of Na2Cr2O7 in electrolyte. The D. C. consumption is 3700±100kW · h/t NaClO3. The cell can be operated steadily.
