Description
Technical field
The utility model relates to a kind of EDI electrodeionization dialyzer that is used to produce high purity water.
Background technology
Existing electrodeionization dialyzer generally includes cathode compartment and anolyte compartment, be arranged alternately in desalting chamber and concentration compartments between cathode compartment and the anolyte compartment, each desalting chamber separates by anion-exchange membrane and cationic exchange membrane and two adjacent concentration compartmentss respectively, each desalting chamber is filled with Zeo-karb and the anionite-exchange resin that forms mixed bed, and the chamber compartment that forms negative electrode is filled with conductive bead or ion exchange resin.Existing anolyte compartment be by positive plate, anionic membrane and between the chamber compartment constitute, cationic exchange membrane is not established in the centre, chlorion can see through anionic membrane and separate out chlorine on positive plate, these chlorine can with positive plate and the ion exchange resin of being filled generation intensive oxidizing reaction, thereby reduced the work-ing life of the ion exchange resin of positive plate and filling greatly; The chamber compartment of the anolyte compartment that also has is that the dividing plate by web form constitutes, and processing is complicated, and cost is higher.
The utility model content
The purpose of this utility model is to overcome above shortcoming, and a kind of work-ing life of the ion exchange resin that can increase positive plate and filling and the electrodeionization dialyzer that processing is simple, cost is low are provided.
The technical solution of the utility model comprises cathode compartment and anolyte compartment, be arranged alternately in desalting chamber and concentration compartments between cathode compartment and the anolyte compartment, each desalting chamber separates by anion-exchange membrane and cationic exchange membrane and two adjacent concentration compartmentss respectively, each desalting chamber is filled with Zeo-karb and the anionite-exchange resin that forms mixed bed, the chamber compartment of cathode compartment is filled with conductive bead or ion exchange resin, it is characterized in that the anolyte compartment increases a cationic exchange membrane between positive plate and anion-exchange membrane, the anolyte compartment is separated into two compartments, being filled with the ion exchange resin of Zeo-karb or mixed bed between positive plate and cationic exchange membrane, is best with the Zeo-karb; Being filled with the ion exchange resin of anionite-exchange resin or mixed bed between cationic exchange membrane and anion-exchange membrane, is best with anionite-exchange resin.
The concentration compartments that each is alternately arranged, respectively by two cationic exchange membranes and Zeo-karb of filling between them or mixed bed resin, add two anion-exchange membranes and anionite-exchange resin of filling between them or mixed bed resin, add the mixed bed exchange resin of filling between above cationic exchange membrane and the anion-exchange membrane and constitute.Add the complex rare-earth element in this mixed bed exchange resin, the ion exchange resin of its mixed bed is 100 with the ratio of complex rare-earth element: 1-1000000: 1.
Each concentration compartments of alternately arranging increases a bipolar mould between cationic exchange membrane and anion-exchange membrane, filling male ion-exchange resin or mixed bed resin between cationic exchange membrane and bipolar mould are filled anionite-exchange resin or mixed bed resin between bipolar mould and anion-exchange membrane.
After the utility model is separated into two compartments with the anolyte compartment, can overcome chlorion effectively and on positive plate, separate out chlorine through anionic membrane, the ion exchange resin generation intensive oxidizing reaction of having avoided chlorine and positive plate and having been filled, thus can strengthen positive plate and filling ion exchange resin work-ing life and processing is simple, cost is low.
