Electrodialyzer common electrode plate

An electrodialyzer common electrode plate is disclosed, an electrodialyzer mainly comprises a membrane stack, a clamping device, and an electrode plate, the electrode plate is divided into side electrodes and a common electrode, the side electrodes are at both sides of the membrane stack, a middle electrode is the common electrode, both ends of the common electrode are respectively provided with water distribution ends, water of freshwater chambers and concentrated water chambers respectively gather together to a freshwater outlet pipe and a concentrated water outlet pipe arranged on the upper water distribution end of the common electrode, a freshwater inlet pipe and a concentrated water inlet pipe are respectively connected, by pipes, with a freshwater inlet pipe and a concentrated water inlet pipe of the lower water distribution end of the common electrode, a water flow enter from the lower end into the membrane stack by the freshwater inlet pipe and the concentrated water inlet pipe, the electrodialyzer common electrode plate is simple and reasonable in structure, is beneficial for full air emissions, prevents accumulation of air in the membrane stack, and overcomes the firing membrane and other characteristics in the prior art.
