Description
Technical field
The invention belongs to water treatment facilities, particularly a kind of multistage electrodialysis brackish water desalination device.
Background technology
At present, existing electrodialysis desalination device has lamina tecti, bottom plate, gasket seal, positive electrode, negative electrode, water conservancy diversion
Duct and one group of spaced positive and negative ion pellicle composition, this electrodialysis desalination device raw water are flowed into from one end, separated
Solution after desalination flows out from the other end, and therefore, electrodialysis desalination flow is short, and desalting efficiency is poor.
Traditional iontophoretic device only has one group of power supply power supply, when handling the water of high salinity, high salinity, due to the characteristic of electricity
Power supply can be caused to burn resistivity is low, whole equipment can all be stopped, it is thus impossible to ensure that electrodialysis plant is continual and steady
Work.
Existing iontophoretic device electrod assembly and power supply unit damage will result in whole equipment can not work and water outlet not
Can normally, integral replacing cost is too high after so damaging, and downtime, long operating environment requirements were high, and maintenance technology requires high.
It is an object of the invention to provide a kind of desalination long flow path, desalting efficiency height, little power consumption, every grade of electric osmose unit by independence
Power supply is powered, and the parts of every grade of electric osmose unit are capable of the multistage electrodialysis brackish water desalination device of convenient and swift replacing, avoided
More than it is overall the defects of.
The content of the invention
To reach above-mentioned purpose, technical scheme provided by the present invention is a kind of multistage electrodialysis brackish water desalination dress
Put, it includes power supply, warning device, lamina tecti, bottom plate, is located at total close of the cavity that is formed between lamina tecti and bottom plate
Gasket, positive electrode plate, negative electrode plate, concentrated water water conservancy diversion duct, fresh water water conservancy diversion duct and one group of interval ordered arrangement cavity block and
Anode membrane, it is characterized in that being separated with ordered arrangement between adding one group side by side again in the cavity formed between lamina tecti and bottom plate
Cavity block and anode membrane, concentrate recirculation duct and fresh water backflow duct are set in bottom plate.
Preferentially, the power supply is every grade of module independent current source, is easy to quick-replaceable after damage, effluent quality is not by indivedual
Unit is damaged and influenceed.
Preferentially, pole water water conservancy diversion duct, the bottom are additionally provided with the cavity formed between the lamina tecti, bottom plate
Pole water backflow duct is provided with plate, is connected with pole water water conservancy diversion duct.
Preferentially, detection warning device is provided with the cavity formed between the lamina tecti, bottom plate, in time will be easy to
Trouble point cuts off and notifies staff to change in time in time.
Preferentially, stand-alone shell is additionally provided with outside every grade of separate cap plate, bottom plate is easy to quick replacing in time internal
Electrode and zwitterion film.
Preferentially, described lamina tecti is provided with water inlet, water outlet, concentrated water outlet.
Preferentially, the water outlet of the previous stage communicates with the water inlet of rear stage.
Preferentially, all flowed out by concentrated water pipeline the concentrated water outlet per one-level.
What the present invention had has the advantages that：A kind of multistage electrodialysis brackish water desalination device of the present invention, is adopted
Added outside with electrodialysis plant under DC electric field effect, utilize selection of the anion and cation exchange membrane to solution middle-jiao yang, function of the spleen and stomach anion to pass through
Property, make a kind of process separated in solution in the solute of ionic condition with solvent, the process is in a device without the storage of solute
With accumulation, the transfer of the change, only ion of phase does not occur yet for solution.Therefore, solution is after electrodialysis, a part of solution
Solute transfer reduce（That is desalination process）, the solute increase of another part solution（That is concentration process）, pass through ad hoc flowing water
Road respectively collects dense, fresh water, and the concentrated water drained into outside membrane stack is drained, fresh water collecting, is achieved that electrodialytic desalination
Process.
The present invention uses multigroup yin, yang electric osmose EDBM desalination, therefore electrodialysis long flow path, and desalting efficiency is high, unit
Time aquifer yield is big, power consumption is small, independent current source power supply can be continual and steady work, zero to the electrodialysis plant of damage
Part can be changed conveniently, substantially pollution-free to environment, the major advantage such as simple to operate.
Specific implementation method
Wherein, embodiment 1：The present invention can be to equipment automatic detection warning, and equipment component is conveniently changed.
A kind of multistage electrodialysis brackish water desalination device, it includes lamina tecti, bottom plate, is located in lamina tecti and bottom plate
Between the total gasket seal of the cavity that is formed, positive electrode plate, negative electrode plate, concentrated water water conservancy diversion duct, fresh water water conservancy diversion duct and one
The cavity block and anode membrane of group interval ordered arrangement, it is characterized in that adding side by side again in the cavity formed between lamina tecti and bottom plate
If being separated with the cavity block and anode membrane of ordered arrangement between one group, concentrate recirculation duct and fresh water backflow duct are set in bottom plate.The top
Detection warning device is additionally provided with the cavity formed between cover plate, bottom plate, when the electrode or zwitterion of iontophoretic device
Exchange membrane damages, and warning device detects that electric current is excessive, warning device alarm, cuts off the electricity supply, notifies staff to change in time
