Specific embodiment
Below with reference to Fig. 1 and Fig. 2, the present invention will be further described:
As shown in Figure 1, a kind of electrode structure of capacitor deionizing instrument, including anode 151 and cathode 152, in anode 151
Surface includes one layer of cationic barrier layer 21, or/and includes one layer of cathode barrier layer 22 on 152 surface of cathode；Cation stops
Layer 21 only allows anion to pass through, and cation can not pass through；Cathode barrier layer 22 only allows cation to pass through, and anion can not lead to
It crosses.
Specifically, including multiple positive 151 and multiple cathode, they are all disposed in parallel, the cathode 152 of an outermost end
It is clamped between cathode panel 32 and cathode barrier layer 22, the anode 151 of another outermost end is clamped in cationic barrier layer 21
Between positive panel 31, other every two positive and negative anodes are integrated into a double-face electrode 153, and multiple double-face electrodes 153 are clamped in
Between an above-mentioned anode and a cathode.
Advantage:
1, cyclic annular, it is easy sealing, it is water-tight；
2, electrode size is small, diameter 150-500mm, easy to produce；
3, circumference water inlet, center of circle water outlet, stock utilization are high.Because water inlet salt concentration is relatively high, in circular contact
Area is larger, and when water flow gradually flows to the center of circle, salt content is gradually decreased, and the area of contact also gradually becomes smaller, electrode material
Utilization rate maximizes.
Hereafter only the present invention will be described for adding amberplex: being constituted the yin, yang of electrochemical desalting unit
Granular activated carbon, activated carbon felt, carbon nanotube, carbon aerogels, graphene etc., denominator can be used in extremely three-diemsnional electrode
It is large specific surface area, good conductivity.
The anode of electrochemical desalting unit is constituted under long-time power on condition, oxidation reaction can occur for anode material, single
Matter carbon can be oxidized to the acidic-groups such as hydroxyl, carboxyl, carbonyl, these groups have cation exchange property, can and water in
Ion exchange occurs for the cation such as calcium ion, potassium ion, similar to the function of ion exchange resin.And as anode, I
Required for function be adsorpting anion, rather than exchange cation is not occupied if there is the cation of exchange exists
Adsorption potential influences the adsorption capacity of unit mass anode, while the positive electricity of anode also can generate repulsive interaction to cation, reduce
Current efficiency, when the situation reaches ultimate attainment, electrochemical desalting unit can thoroughly disappear except salt functional, and current efficiency is down to zero.
Designed zwitterion barrier layer, is exactly amberplex used in electrodialysis in fact in the present invention, it
Be it is a kind of containing ionic group, to the ion in solution have selection through ability polymeric membrane because generally application when
The ion-selective permeability for mainly utilizing it, so also referred to as ion-selective permeability film.It can stop through anion
Cation is known as cationic barrier layer, and anion is stopped through cation is known as anion barrier layer.
When ion selectivity material is not present in electrode surface, by electric current on the one hand due to the electrical opposite grain of absorption
Sub (useful work), on the other hand for repelling electrically identical particle (idle work), therefore the current efficiency adsorbed is not
100%.And when there are ion selectivity material, do not considering that other energy are time-consuming, the current efficiency for absorption theoretically connects
Nearly 100%.
Another factor of limitation Electro Sorb application is reproduction speed at present, because electro-adsorption demineralization is intermitten service, when
After electrode material adsorption saturation, need to regenerate it.When ion selectivity material is not present, when regeneration, can only be powered short
It connects, parses charged particle from material by natural diffuseness, it is usually relatively slow, because having electric field power drive when absorption, and regenerate
When there is no electric field power drive, natural diffuseness can only be leaned on, effective production water efficiency of Electro Sorb reduces.
And the present invention is added to the sub- selective substances of a leafing in electrode surface, in this way, can be application reversed electricity when regeneration
, regenerative drive power is provided, keeps regeneration very thorough, and can greatly shorten the reproduction time.Be Electro Sorb production water efficiency it is very big
It is promoted.
The present invention adds a positive and negative amberplex on cathode and anode surface respectively, in the anion exchange of anode surface
Film only allows anion to pass through, accordingly even when anode material is when long-term work aoxidizes, although surface can generate some tools
There is the acidic functionality of ion exchange, but since cation can not be contacted, because without ion exchange occurs, thus
The adsorption potential of electrode surface will not be occupied, even if anode still plays suction-operated in the state of oxidation, and be kept higher
Current efficiency, in addition, anode surface generate acidic functionality be it is hydrophilic, be more advantageous to the desalination of aqueous solution.Therefore,
The present invention overcomes the drawbacks of anodic oxidation, while having played anodic oxidation bring benefit.
The working principle on zwitterion barrier layer is: barrier layer be stop sewage in need to be isolated like charges from
Presence of the son near electrode surface is (such as the anion Cl in anode absorption water-、SO4 2-Deng, and stop corresponding cation Na+、
Ca2+Deng it is close, but in order to enable whole charge, which reaches balance, has the H that hydrolytic dissociation comes out+Come in supplement.Similarly, exist
When negative terminal surface Liquidity limit, other anion cannot be close to only OH-To supplement).In this way, being exactly in positive electrode surface
The anion and a part of H to be separated come out in sewage+Hydrogen ion, negative terminal surface are corresponding cation and a part of OH-Hydrogen-oxygen
Radical ion, and the various zwitterions in the water flowed out will be fewer and fewer, extra hydrogen ion and hydroxide ion also can phases
Mutually neutralize.
Following table is that the present invention makes with the prior art without using the Contrast on effect table after ion barrier:
| Without ion barrier | Include ion barrier | |
| Working time | 30min | 30min |
| Reproduction time | ≥30min | ≤15min |
| Effectively produce the water time | < 50% | > 67% |
