Electrodialysis is a membrane separation device that uses the selective permeability of a membrane to separate charged electrolyte from uncharged substances in water to achieve the desired purposes of desalination, concentration, etc. The internal major components of electrodialysis are the anion and cation exchange membranes and separators. The compartment formed by the partition is a passage through which the liquid flows. The compartment through which the material passes is a desalination chamber, and the compartment through which the concentrated water passes is a concentration chamber. Under the action of a direct current electric field, the potential difference is used as a driving force, and the selective permeability of the anion and cation exchange membranes to anions and cations is utilized to enable ions to migrate from one part of water to the other part of water. Ions in the desalting chamber migrate to the concentrating chamber, and ions in the concentrating chamber cannot migrate to the desalting chamber due to the selective permeability of the membrane, namely inorganic salts in the wastewater are desalted or concentrated. The two ends of the electrodialysis are respectively provided with an electrode, a compartment net, a water distribution plate and a clamping plate, and are fastened by a screw and a nut to form the electrodialysis membrane group device. The electrode is usually fixed on a water distribution plate, the water distribution plate is provided with a water inlet and a water outlet of desalted liquid or concentrated liquid and a water inlet and a water outlet of electrode liquid, a water distribution runner of the water distribution plate guides the desalted liquid or the concentrated liquid to electrodialysis, and the electrode liquid is guided to the surface of the electrode; screw holes are formed in the edges of the clamping plates and used for fastening the membrane group device. Referring to fig. 1, the existing electrode frame includes a frame body 1 'and mounting holes 11' formed in the frame body, but the existing electrode frame is used by embedding a compartment screen, and the screen around the electrode frame is easy to generate concave-convex deformation to form a water flow dead zone when in use, and the water flow is easy to concentrate and flow in a central area to enable the local temperature in the electrode water chamber to be increased due to uneven distribution of the water flow, so that the service lives of electrode plate coatings and electrode films are not protected.
