[0002] IE technology is a new type of electrolytic technology, which uses metal ions loaded on resin as the metal source for metal ion electrodeposition, replacing the traditional electrolytic use of metals, metal salts, metal oxides or hydroxides as the metal source. During the electrolytic process, the electrolytic solution continuously passes through the metal-loaded resin, exchanges the metal ions loaded on the resin, and replenishes them into the electrolyte, thereby maintaining the metal content in the electrolyte and allowing the metal electrodeposition to proceed continuously and stably.

[0003] Resin loading of metal ions needs to be carried out in a dedicated ion exchanger (or column). The resin needs to complete transformation, cleaning, ion exchange and metal loading processes in the ion exchanger. Traditional ion exchangers mainly have fixed beds, moving beds, floating beds and other forms. Due to the disadvantages of resin channeling, wall effect, agglomeration and other drawbacks of traditional ion exchanger resin beds, it is difficult to achieve a complete state during the resin loading of metal ions, cleaning, transformation and regeneration processes.

[0006] The Chinese patent application number is 200820182831.5, and the application date is December 24, 2008. It discloses a non-disassembly fixed bed ion exchange adsorption equipment, in which the liquid seepage pipe is composed of three layers, the outermost layer is a perforated fiberglass support pipe, and its pore size is smaller than the sand and gravel particle size of the filter layer, the middle layer is a double-layer stainless steel filter mesh, and its pore size is smaller than the particle size of the adsorption resin, and the innermost layer is a perforated inner support plastic pipe.
