Technical field
The present invention relates to water technology, relate in particular to a kind of pure water generation equipment.
Background technology
Automobile antifreeze solution only is made into the certain density aqueous solution just can give full play to its antifreeze effect.Often contain a large amount of dissolved matters in the tap water that uses, river, the lake water, as metal ions such as calcium, magnesium, potassium, sodium, also contain a lot of negatively charged ion such as sulfate radical, phosphate radical and chlorion or the like, these zwitterions that exist in the water can influence the quality of deicing fluid.For example: phosphate radical and sulfate ion under the condition of heating with solution in positively charged ions such as calcium, magnesium generate incrustation scale, blocking pipe reduces heat transfer efficiency; And chlorion or sulfate ion can aggravate the corrosion of cooling system when reaching finite concentration.Therefore, water quality is extremely important, in process of production, must use pure water.
In conventional art, the preparation of preparation pure water all needs to consume a large amount of soda acids, soda acid is in production, transportation, storage and use, can bring pollution inevitably to environment, also can be to the corrosion of equipment, the injury that human body is caused, simultaneously, utilize the maintenance cost of the pure water producing apparatus of soda acid to remain high, make that the preparation cost of pure water is very high.
Summary of the invention
The present invention is intended to propose a kind of pure water production technology in conjunction with electrodialytic technique and ion exchange technique, avoids the use to soda acid, reduces the manufacturing cost of pure water.
According to the present invention, a kind of production equipment for purified water is proposed, comprising:
Pair of electrodes comprises a positive electrode and a negative potential;
Be clipped in one group of chamber unit between positive electrode and the negative potential, each chamber unit comprises adjacent freshwater room and dense hydroecium, be provided with ion-exchange membrane between freshwater room and the dense hydroecium, in freshwater room, fill Zeo-karb and the anionite-exchange resin that mixes, have reflux line between dense hydroecium and the freshwater room;

The production equipment for purified water that the present invention proposes utilizes brine electrolysis that ion exchange resin is regenerated, and need not chemical regeneration, saves bronsted lowry acids and bases bronsted lowry, and this equipment can move continuously and stable water quality can be provided, and greatly reduces the production cost of pure water.
Description of drawings
Fig. 1 has disclosed the structure iron according to the production equipment for purified water of one embodiment of the invention.
Embodiment
With reference to shown in Figure 1, the present invention proposes a kind of production equipment for purified water, comprising: electrode, chamber unit, water inlet, purified water collecting opening and water port.
This pair of electrodes comprises a positive electrode 101 and a negative potential 102.
One group of chamber unit 103 is clipped in one group of chamber unit between positive electrode 101 and the negative potential 102, and each chamber unit comprises adjacent freshwater room 104 and dense hydroecium 105, is provided with ion-exchange membrane 106 between freshwater room 104 and the dense hydroecium 105.In one embodiment, ion-exchange membrane 106 comprises cationic exchange membrane 107 and anion-exchange membrane 108.Ion-exchange membrane 106 can comprise multilayer, such as cationic exchange membrane 107 and anion-exchange membrane 108 at interval.107 of cationic exchange membranes allow cation permeation, and 107 of anion-exchange membranes allow negatively charged ion to see through.In freshwater room 104, fill Zeo-karb 109 and the anionite-exchange resin 110 that mixes.Have reflux line 111 between dense hydroecium 105 and the freshwater room 104, the dense water of a part in the dense hydroecium 105 can be back in the freshwater room 104 to keep the regeneration of Zeo-karb 109 and anionite-exchange resin 110 by reflux line 111.
Water inlet 112 is connected to each chamber unit 103.Purified water collecting opening 113 is connected to the freshwater room 104 of each chamber unit.Water port 114 is connected to the dense hydroecium 105 of each chamber unit.
The principle of work of this production equipment for purified water is as follows:
Positive and negative electrode produces electric field, electric field makes the water molecules in the water of the chamber unit that enters by water inlet resolve into H+ and OH-, these ions in the water are subjected to the attraction of respective electrode, pass the direction migration of Zeo-karb and anionite-exchange resin to institute's ion-exchange membrane, when these ions see through ion-exchange membrane, after for example Jian Ge cationic exchange membrane and anion-exchange membrane entered dense chamber, H+ and OH-were combined into water.This positive and negative ion, for example the generation of H+ and OH-and migration are the mechanism that ion exchange resin is achieved cyclic regeneration.
Except the H+ and OH-ion that are decomposed to form by water molecules, also have foreign ions such as Na+ and CI-in the water, these foreign ions meeting absorptions are to corresponding ion exchange resin.When the foreign ion such as Na+ and CI-is adsorbed on the ion exchange resin, will be as the ion exchange reaction in the common mixed bed, and correspondingly displace H+ and OH-.In case the foreign ion in ion exchange resin also joins H+ and the OH-migration to the ion-exchange membrane direction, these foreign ions will pass ion exchange resin continuously and enter dense hydroecium until seeing through ion-exchange membrane.These foreign ions focus in the dense hydroecium, will contain a large amount of ionic concentrated water drainages by water port and go out.And stay most of ionic pure water that has been exactly away in the freshwater room, purified water collecting opening is collected pure water from freshwater room.Regeneration of ion-exchange resin needs the ion of some amount to exist, and therefore, reflux line connects dense hydroecium and freshwater room, and the dense water of the part in the dense hydroecium can be back in the freshwater room to guarantee the cyclic regeneration of ion exchange resin by reflux line.
The pure resistivity of water that adopts the present invention to obtain can reach 10-15M Ω/cm.
The production equipment for purified water that the present invention proposes utilizes brine electrolysis that ion exchange resin is regenerated, and need not chemical regeneration, saves bronsted lowry acids and bases bronsted lowry, and this equipment can move continuously and stable water quality can be provided, and greatly reduces the production cost of pure water.
