Description
Technical field
The utility model relates to a kind of roll type electric salt eliminator component element, relates in particular to a kind of dense, freshet to staggered, is provided with the roll type electric salt eliminator component element of the water-distributing device of dense, fresh water on pipe core.
Background technology
In the method for the water treatment that existing process water desalination is purified, comparatively Xian Jin method is electrodialytic technique and ion exchange technique to be combined produce ultrapure water, promptly electric desalination (EDI) technology.The EDI technology is under the effect of DC electric field, utilizes the selection perviousness of anion and cation exchange membrane to zwitterion in the solution, realizes ionic removal or concentrated.Typical electric desalination plant generally comprises positive and negative electrode, between positive and negative electrode, and the anion and cation exchange membrane of arranging alternately, and the electrode vessel, dense hydroecium and the freshwater room that are separated by the negative and positive film.Water to be processed enters freshwater room, and under the effect of ion exchange resin and electric current, the charged ion in the water is anode and cathode direction migration respectively, and positively charged ion moves to cathode direction, enters into dense hydroecium by cationic exchange membrane from freshwater room.Similarly, electronegative ion anode direction migration enters into dense hydroecium by anion-exchange membrane from freshwater room.The ion continuation meeting that enters into dense hydroecium is moved on original migratory direction, but because the selective permeation characteristic of ion-exchange membrane, promptly cationic exchange membrane only allows that positively charged ion passes through, and anion-exchange membrane only allows that negatively charged ion passes through, so the ion in dense hydroecium can't return in the freshwater room.So just reached the purpose of water in the freshwater room of cleansing.
In the EDI assembly, it is different that various ionic in the fresh water are deviate from order, as shown in Figure 1.At first being that high valence ion is deviate from, secondly is easily to deviate from ion at a low price to be deviate from, and is that weak ionization ion and hydrogen ion and hydroxide ion etc. are removed at last.The required electric current that provides (density) is provided various ionic also is different, and commute removes ionic, and to deviate from required electric current low, and weak Ionized difficulty removes ionic, and to deviate from required electric current then high.So preferred component design should be low relatively at the electric current of fresh water water inlet place, and high relatively at the electric current of fresh water water outlet place, deviates to help that weak Ionized difficulty is removed ionic.
Scission reaction also can take place in the water in the freshwater room under the effect of electric current, particularly at the purity of water higher EDI assembly water side place's ion exchange resin and ion-exchange membrane interface, the scission reaction of water takes place easily.Scission reaction has generated hydrogen ion and hydroxide ion, and they play regeneration to ion exchange resin.Therefore, the EDT technology is the process that realizes without soda acid ion exchange resin cyclic regeneration.
Electricity desalination technology has been widely used in semi-conductor, medicine, the pure water preparation in electric power and the field of food.Electricity desalination assembly has plate and frame and rolling design, and wherein rolling EDI assembly has the branch of concentric rolling and spiral wound again.Present electric salt eliminator component element generally is that dense water enters in pipe core, flow through behind the film bag, flow out from pipe core, cut off in the middle of the pipe core, the film bag is a radial opening, opening links to each other with opening on the pipe core, is provided with in the film bag at interval, also is provided with the sealed collection tube of mechanical fastener at axle head and collects fresh water.
