The present invention discloses a novel membraneless
electrodeionization device structure. It comprises a composite top cover, a composite bottom cover, a cylindrical shell and an
ion exchange resin layer. The upper end of the cylindrical shell is provided with a composite top cover, and the lower end is provided with a composite bottom cover. The composite top cover and the composite bottom cover have the same structure and are symmetrically arranged at the middle and two ends of the cylindrical shell. The cylindrical shell is filled with an
ion exchange resin layer. The composite top cover and the composite bottom cover are pressed toward the middle of the cylindrical shell at both ends of the cylindrical shell, thereby pressing the
ion exchange resin layer. The composite top cover / bottom cover both comprise an upper interface, an upper cable sealing joint, a top cover plate, an upper
electrode connecting rod, an upper porous pressing plate, an upper resin filter plate and an upper
electrode net. In the present invention, the resin layer can be evenly pressed under the action of the composite top cover and the composite bottom cover, and the upper and lower resin particles are always kept in
close contact, which effectively reduces the unfavorable
water flow distribution condition of the resin layer, effectively ensures good regeneration of the resin, simplifies the structure, and is easy to install and maintain.
