Abstract

The utility model discloses a kind of EDI module water purifier, including clamping plate, negative pole water plate, positive pole water plate, pole hydroecium, pure water rooms and dense hydroecium, described clamping plate are positioned at outermost, described negative pole water plate and positive pole water plate are positioned at the inner side of clamping plate, described pole hydroecium is positioned at negative pole water plate and the inner side of positive pole water plate, described pure water rooms and dense hydroecium staggered cycles successively and is arranged on the inner side of pole hydroecium.This EDI module water purifier, under the effect of external electric field, in water, electrolyte ion carries out the electrodialytic process of selective migration by ion exchange membrane；The regenerative process that exchanger resin is carried out by the hydrolysis of hydrion and hydroxide ion and exchanger resin itself produced by electrodialytic polarization process, it is achieved the continuous deionization of EDI；Between pure water rooms and dense hydroecium, carry out purification deionization desalination by constantly circulate, good desalination effect can be reached, produce the pure water meeting demand.

Description

A kind of EDI module water purifier

Technical field

This utility model belongs to water purifier technical field, is specifically related to a kind of EDI module water purifier.

Background technology

EDI is a kind of desalination new technology electrodialysis and ion exchange phase combined mutually.This technical process power taking Dialysis and ion both length of exchange, make up the short of the other side, i.e. utilize ion exchange energy advanced desalination to overcome electrodialysis to polarize And desalination is thorough, electrodialysis polarization is utilized again to occur water power to realize resin from regeneration from generation hydrion and hydroxide ion The defect regenerated by chemical agent after overcoming efficiency lost resin.Thus EDI technology is a kind of perfect desalination process.Current EDI module water purifier desalination effect is not fine, and the water produced is not well positioned to meet demand.Propose a kind of for this EDI module water purifier.

Utility model content

The purpose of this utility model is to provide a kind of EDI module water purifier, to solve proposition in above-mentioned background technology Problem.

For achieving the above object, this utility model provides following technical scheme: a kind of EDI module water purifier, including clamping plate, Negative pole water plate, positive pole water plate, pole hydroecium, pure water rooms and dense hydroecium, described clamping plate are positioned at outermost, described negative pole water plate and positive pole Water plate is positioned at the inner side of clamping plate, and described pole hydroecium is positioned at negative pole water plate and the inner side of positive pole water plate, described pure water rooms and dense hydroecium Staggered cycles is arranged on the inner side of pole hydroecium successively.

Preferably, the spatial group that described pure water rooms is occupied by the mixture iron exchange resin between anion and cation exchange membrane Become.

Preferably, described dense hydroecium is enumerated together by a number of EDI pure water rooms unit, uses ring between pure water rooms Each EDI pure water rooms unit is separated by shape sealing member, the space composition between two EDI pure water rooms unit.

Preferably, described pole hydroecium is by the sky using annular seal to be constituted between EDI battery lead plate and EDI the first hydroecium Between form.

Technique effect of the present utility model and advantage: this EDI module water purifier, under the effect of external electric field, be electrolysed in water Matter ion carries out the electrodialytic process of selective migration by ion exchange membrane；Hydrion produced by electrodialytic polarization process Regenerative process exchanger resin carried out with the hydrolysis of hydroxide ion and exchanger resin itself, it is achieved EDI goes continuously Ion；Between pure water rooms and dense hydroecium, carry out purification deionization desalination by constantly circulate, good desalination can be reached Effect, produces the pure water meeting demand.

Accompanying drawing explanation

Fig. 1 is structured flowchart of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

This utility model provides a kind of EDI module water purifier as shown in Figure 1, including clamping plate, negative pole water plate, positive pole water Plate, pole hydroecium, pure water rooms and dense hydroecium, described clamping plate are positioned at outermost, and described negative pole water plate and positive pole water plate are positioned at clamping plate Inner side, described pole hydroecium is positioned at negative pole water plate and the inner side of positive pole water plate, and described pole hydroecium is by EDI battery lead plate and EDI the first water Using the space composition that annular seal is constituted between room, described pure water rooms and dense hydroecium staggered cycles successively are arranged on pole water The inner side of room, the space that described pure water rooms is occupied by the mixture iron exchange resin between anion and cation exchange membrane forms, described Dense hydroecium is enumerated together by a number of EDI pure water rooms unit, uses annular seal by pure for each EDI between pure water rooms Hydroecium unit separates, and the space composition between two EDI pure water rooms unit, this EDI module water purifier, in the effect of external electric field Under, in water, electrolyte ion carries out the electrodialytic process of selective migration by ion exchange membrane；Electrodialytic polarization process institute The regenerative process that exchanger resin is carried out by the hydrion produced and the hydrolysis of hydroxide ion and exchanger resin itself, real The existing continuous deionization of EDI；Between pure water rooms and dense hydroecium, carry out purification deionization desalination by constantly circulate, can reach Good desalination effect, produces the pure water meeting demand.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature Carry out equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
