Abstract
The invention discloses a device used for a rotational-flow electrolysis method, which represent new technology for performing selective electrolysis (electrode position) on valuable metals and are particularly suitable for performing selective electrolysis (electrode position) separation and purification on low-concentration solution, which has complex composition in the metallurgy industry, and stripping heavy metal ions from waste water. Due to the adoption of the technology, the problems of small electrolytic current density, non-uniform current distribution, great difficulty in removing impurities from solution, long process flow, high production cost, low overall efficiency and the like existing in the electrolysis process of conventional flat plate (frame) electrolysis technology (device) can be solved effectively. Moreover, an electrolysis technical solution (device), which has the advantages of high efficiency, reliability, simple process flow, simple and convenient operation and low cost in the presence of complex solution composition, is provided.
Description
technical field [0001] The invention relates to an electrolysis method and its device, in particular to a swirling flow electrolysis method and its device which make the solution swirl and flow. Background technique [0002] The swirl electrolysis technology (device) is based on the theoretical precipitation potential of each metal ion (E ￠ ) difference, that is, as long as the metal to be extracted has a large potential difference with other metal ions in the solution system, the metal with a higher potential is easy to preferentially precipitate at the cathode. The unfavorable factors avoid the unfavorable situation that the traditional electrolysis (electrowinning) method is affected by various factors (ion concentration, ion basic potential, cathode and anode potential, concentration polarization, pH value, overpotential, etc.) during the electrolysis process. High-quality metal products can be produced through simple technical conditions. At the same time, this technol...
