Description
Technical field
The utility model relates to a kind of equipment with the electrochemical method treating water.Relate in particular to a kind of concentrated salt manufacturing electrodialyzer that can from the sea water desaltination waste liquid, produce concentrated saltwater brine.What it can be widely used in that sea water desaltination, brackish water desalination, seawater concentrate useless concentrated solution after salt manufacturing and the industrial water supply desalination concentrates salt manufacturing once more.
Background technology
Existing water treatment electrodialyzer, it is based on electroosmose process, promptly in DC electric field, utilize ion-exchange membrane, make the positive and negative ion in water or the solution make directional migration to anion-exchange membrane, cationic exchange membrane respectively, electrolyte transfer in one road water is gone to another Lu Shuizhong, thereby reach the desalination purpose.Above-mentioned existing electrodialyzer is used for seawater more, the brackish water desalination comes potable water, desalination water, but because the ion-exchange membrane of this electrodialyzer can't be produced the saltwater brine of high density again from useless concentrated solution, thereby entered again in the sea mostly from a large amount of useless concentrated solutions that electrodialyzer is discharged, cause local concentration of seawater too high easily like this, destroy the ecotope in this marine site, part thereby cause local seawater temperature to rise.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of being specially adapted to produce the concentrated salt manufacturing electrodialyzer that concentrates saltwater brine from the useless concentrated solution of sea water desaltination.
The utility model solves the problems of the technologies described above by following technical proposals: a kind of concentrated salt manufacturing electrodialyzer, comprise anion-exchange membrane, cationic exchange membrane, dividing plate, negative electricity pole plate and positive electricity pole plate, be coated with on the described anion-exchange membrane and select the perviousness coating, be coated with on the described cationic exchange membrane and select the perviousness coating, scribble the colloid sealing ply between described anion-exchange membrane, cationic exchange membrane, dividing plate, negative electricity pole plate and the positive electricity pole plate.
As preferably, mill in the described yin, yang battery lead plate and be provided with electrode solution and reaction product is drawn pipe.
As preferably, described pipe offers some electrode solution through holes on it is positioned at the pipeline section of battery lead plate.
Be coated with on the described ion-exchange membrane and select the perviousness coating, make Na
+, Cl
-Ion has preferentially selects high-permeability, Na well
+, Cl
-Migrate to the concentration compartments that concentrates the salt manufacturing electrodialyzer ion high-permeability, make the saltwater brine that forms high density in the sodium chloride solution of concentration compartments, and then be promoted to sodium chloride saturated solution from saltwater brine, produce sea salt again by mature technology.
According to above-mentioned principle, this concentrated salt manufacturing electrodialyzer is except selecting the suitable Na that makes
+, Cl
-Ion has preferentially to be selected outside the high-permeability coating well, it is dense, freshwater room never allows string to leak, otherwise because dense, the freshwater room concentration difference is bigger, the fresh water string leaks extremely, and dense hydroecium reduces dense water concentration greatly, concentrated cost increases greatly, make that producing sea salt does not have any economic benefit, and, therefore scribble the colloid sealing ply between anion-exchange membrane, cationic exchange membrane, dividing plate, negative electricity pole plate and the positive electricity pole plate of this concentrated salt manufacturing electrodialyzer because the string leakage makes the sea salt purity of producing reduce greatly.
Saltiness owing to dense water, fresh water and electrode solution in this technology is all very high in addition, actuating current is very big, the electrode district generated reactive gas is many, temperature is high, therefore a kind of concentrated salt manufacturing electrodialyzer that provides of the utility model also mills in the yin, yang battery lead plate and is provided with electrode solution and reaction product is drawn pipe, substitutes the square groove milling electrode solution extraction channel on the primary electrode plate.
Adopt the utility model of the technical program, its beneficial effect is:
One, is coated with selection perviousness coating on the described ion-exchange membrane, makes Na
+, Cl
-Ion has preferentially selects high-permeability well.
Two,, guaranteed never string leakage between dense, the freshwater room owing to added the colloid sealing ply between ion-exchange membrane and dividing plate, the battery lead plate.
Three, make electrode solution and gas eduction tube with pipe, substitute the square groove milling passage on the primary electrode plate, make the discharge of interior electrode solution of electrode vessel and reaction product more unobstructed, no dead angle guarantees production safety.And milling pipe, to mill the processing of square groove easier.
In sum, adopt this concentrated salt manufacturing electrodialyzer the useless concentrated solution that originally ocean environment is polluted can be concentrated salt manufacturing once more, turn waste into wealth, have bigger social value and economic worth.
