Technical field
The utility model relates to the water treatment system relevant device, a kind of specifically electrochemical de-ionized system oxygen-proof protecting device.
Background technology
At present; In water treatment system, can adopt the equipment of electrochemical de-ionized (EDI) system usually as deep desalting; Its principle is exactly the zwitterion that utilizes in the mixture iron exchange resin planar water; These ions that are adsorbed under the effect of volts DS, are removed through the zwitterion film respectively again simultaneously.
Two freshwater rooms of EDI system and a dense hydroecium ion exchange process are: towards the anodal anionic membrane and towards constituting dense hydroecium between the cationic membrane of negative pole; Towards the anionic membrane of negative pole and between the anodal cationic membrane, form freshwater room.Freshwater room and dense hydroecium sandwich yin, yang ion exchange resin; When water when freshwater room and dense hydroecium flow through; Ion exchange resin has just adsorbed the ion in the water, and the electrode at EDI module two ends provides horizontal DC electric field, and DC electric field drives the adsorbed ion of ion exchange resin and passes ionic membrane; The ionic concn that has consequently reduced water in the freshwater room with increased the ionic concn of water in the dense hydroecium, thereby make that the purity of water is increasingly high in the freshwater room.
According to the influent quality minimum requirements of EDI system, preprocessing system generally adopts pretreatment system and two-pass reverse osmosis (RO) system, and its effluent quality can satisfy module water inlet requirement basically, but the water inlet of EDI system requires the maximum chloride content (Cl in the water
2)＜0.02ppm, what adopt all is city tap-water and the water treatment system water source is general, the waterworks can add sterilizing agent in water.Pretreatment system in water treating equipment is for the removal of these sterilizing agents; That usually adopts is charcoal absorption and adds medicament and reduce processing; These processing modes can limit to some extent, such as gac lost efficacy, and it is not enough etc. that medicament does not add or add concentration.The content of the water inlet control chlorine residue of EDI system, total chlorine is very crucial, badly will cause the module oxidation and causes heavy losses in case control.Want to detect the chlorine residue or the chloride content of monitoring EDI water inlet, can adopt online chlorine residue/total chlorine on-line detector, but because this equipment price is higher, maintenance is complicated, generally can not adopt.

Embodiment
Present embodiment provides a kind of electrochemical de-ionized system oxygen-proof protecting device; Connect as shown in Figure 1; Comprise electrochemical de-ionized module 1 and pure water case 2; Be connected to water inlet pipe 3, rising pipe 4, concentrated water discharge pipe 5 and utmost point water discharge spout 6 on the electrification de-ionized module 1, rising pipe 4 is connected to pure water case 2, is connected to redox potential detector 7 (ORP detector) on the water inlet pipe 3.ORP, redox potential is the abbreviation of English Oxidation-Reduction Potential, the relative extent of its characterized medium oxidisability or reductibility, unit are mv.Rising pipe 4 also is connected to return line 10 through a SV 9.Rising pipe 4 is connected to pure water case 2 through SV 9.Be connected to water quality analyser 11 on the rising pipe 4.All be connected under meter 12 on water inlet pipe 3, rising pipe 4, concentrated water discharge pipe 5 and the utmost point water discharge spout 6.
In pure water equipment, adopt ORP to show to be used for characterizing indirectly the content of chlorine residue, and then guarantee that the EDI module is not corroded by chlorine residue.Online relatively residual chlorine detecting instrument has higher cost performance.Contents of residual chlorine is many, and oxidisability is strong, and redox potential is high; Contents of residual chlorine is few, and reductibility is strong, and redox potential is low.
Redox potential detector 7 is received on the water inlet pipe 3 through an ORP electrode 8.But redox potential can receive the influence of other materials in PH and the water; So before ORP shows online use, generally can contrast portable residual chlorine detecting instrument table, the ORP table carried out numerical value appraise and decide; Confirm the redox potential numerical value under certain residual chlorine concentration; When pure water equipment moved, the addition of control reductive agent made redox potential be lower than this numerical value and gets final product.Generally speaking, the contents of residual chlorine in the water is less than 0.02PPM, then ORP table numerical value can +below the 175mv.
The utility model pretreatment system to water in chlorine residue or total chlorine when handling thoroughly, can play the protection conduct effectively, avoid causing bigger irremediable loss, input cost also is very low simultaneously.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
