Abstract
Description
Technical Field

[0002] The dialyzer is driven by an external DC electric field and utilizes the selective permeability of the ion exchange membrane, that is, cations can pass through the cation exchange membrane, and anions can pass through the anion exchange membrane. The anions and cations move to the anode and cathode respectively. During the ion migration process, if the fixed charge of the membrane is opposite to the charge of the ions, the ions can pass through; if their charges are the same, the ions are rejected, thereby achieving the purpose of solution desalination, concentration, refinement or purification.
[0003] The dialyzer is suitable for solution desalination and concentration treatment, etc., but the current frame dialyzer and spiral dialyzer are difficult to pre-treat the injected solution, and the suspended solids in the solution can easily enter the interior of the dialyzer, which will cause contamination to the anion and cation exchange membrane, and then affect the dialyzer's treatment effect on the solution. Therefore, those skilled in the art provide a flat-plate dialysis device to solve the problems raised in the above background technology. Utility Model Content
