Abstract
The utility model relates to an electrodialysis plate. A main body plate of the electrodialysis plate takes the hollow frame structure of a surface plate, the hollow part is an isolation room and two ends of the main body plate are provided with a plurality of deflector holes, which includes an open deflector hole communicated with the isolation room of the plate on the layer and a closed deflector hole that passes through the plate on the layer but is not communicated with the plate on the layer. The electrodialysis plate is characterized in that: two ends and sides of the main body plate are provided with a slot-shaped liquid flow channel flowing to the isolation room from the open deflector hole. The electrodialysis plate has the obvious advantages of: by arranging the circuitous and winding slot-shaped liquid flow channel at the ends and sides of the plate, lengthening the liquid flow channel between a collecting duct and the isolation room, thus increasing the resistance, reducing 'parasitic current', solving the problem that the overlarge 'parasitic current' in an electrodialyzer of the prior art causes the great decrease of current efficiency, reducing the consumption of electricity and improving the product concentration.
