Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation.

[0024] The specific implementation is as figure 1 As shown, the device includes a composite top cover, a composite bottom cover, a cylindrical shell 11 and an ion exchange resin layer. The upper end of the cylindrical shell 11 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 The structure is the same and the two ends of the cylindrical shell 11 are symmetrically arranged. The ion exchange resin layer 12 is filled in the cylindrical shell 11. The shape shell 11 is pressed in the middle, and then the ion exchange resin layer is pressed.

[0025] The composite top cover includes an upper interface 1, an upper cable sealing joint 2, a top cover plate 3, an upper electrode connecting rod 5, an upper porous pressure plate 8, an upper resin f...

Abstract

The invention discloses a novel membrane-free electrodeionization device structure. The structure comprises a composite top cover, a composite bottom cover, a cylindrical shell and an ion exchange resin layer, the composite top cover is arranged at the upper end of the cylindrical shell, the composite bottom cover is arranged at the lower end of the cylindrical shell, the composite top cover and the composite bottom cover have the same structure and are symmetrically arranged at two ends of the middle 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 compressed towards the middle of the cylindrical shell at two ends of the cylindrical shell to compress the ion exchange resin layer, the composite top cover / bottom cover comprises 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 filteringplate and an upper electrode net. The resin layer can be uniformly pressed under the action of the composite top cover and the composite bottom cover, the upper resin particles and the lower resin particles are always in close contact, the adverse water flow distribution condition of the resin layer is effectively reduced, good resin regeneration is effectively guaranteed, the structure is simplified, and installation and maintenance are easy and convenient.

Description

technical field [0001] The invention relates to a resin regeneration structure, in particular to a novel membraneless electrodeionization device (MFEDI) structure. Background technique [0002] Authorized invention patents (Patent No. 201110048386.X; ZL201210016704.9; ZL201410197346.5; ZL201410760013.9) introduce a membrane-free electrodeionization technology (Membrane-free Electrodeionization, referred to as MFEDI). In principle, the MFEDI device is equivalent to a mixed ion exchange bed that replaces traditional chemical regeneration with electrical regeneration, commonly known as electric mixed bed, which can replace traditional mixed bed and conventional electrodeionization technology, and is widely used in high-purity water treatment. It can be used as a secondary desalination device in a deep desalination system, and it can form a multi-stage deep desalination system with reverse osmosis, mixed bed, etc. [0003] In the original membraneless electrodeionization device...
