The wiring construction of electrode in a kind of capacitor deionizing instrumentTechnical field
The utility model relates to capacitor deionizing instruments, and in particular to the wiring knot of electrode in a kind of capacitor deionizing instrumentStructure.
Background technique
The phenomenon that capacitive deionization technology is using charged electrode surface adsorption water intermediate ion and charged particle, makes molten in waterSolution salt and other charge species are concentrated and realize a kind of novel water treatment technology of water desalination in the surface enrichment of electrode.
Electrode includes adsorption electrode piece and collector, and collector is connected and is electrically connected with adsorption electrode piece, current collection with power supplyBody is also fixed on adsorption electrode on piece, adsorption electrode piece and water intermediate ion by way of adhesion agent or physical connection and with electrochondriaSon interaction.Collector can use metal or nonmetallic.When collector uses metal material, electrochemistry easy to form is rottenErosion, the service life is lower, and has metallics precipitation.
Utility model content
Technical problem to be solved in the utility model be for the above-mentioned state of the art and providing one kind prevents collectorThe wiring construction of electrode in the capacitor deionizing instrument of electrochemical corrosion occurs.
Technical solution adopted by the utility model to solve the above technical problems is as follows: electrode in a kind of capacitor deionizing instrumentWiring construction, including the adsorption electrode piece being electrically connected to each other and collector, the outside of the collector is at least partly coated withWater barrier, the periphery of the water barrier and the adsorption electrode piece are tightly connected, thus by the collector and water segregation.
In order to which water barrier to be connect with adsorption electrode piece, the water barrier and the adsorption electrode piece are viscous by adhesion agentEven or inserting connects.
In order to which water barrier is connect with adsorption electrode piece, the adsorption electrode on piece be equipped with slot, the one of the water barrierEnd adapts in the slot, to realize that the inserting of adsorption electrode piece and water barrier connects.
Preferably, the current collection body portion exposes to the water barrier, the adsorption electrode piece and this exposed segment setElectric body contact is conductive and covers this exposed part collector, water barrier and the adsorption electrode described in the adhesion agent adhesionPiece, so that this exposed part collector is sealed between adsorption electrode piece and water barrier.
Compared with the prior art, the advantages of the utility model are: by setting water barrier and water barrier periphery withAdsorption electrode piece is tightly connected, to prevent collector contact water and electrochemical corrosion occurs collector and water segregation.

Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1 to 4, the wiring construction of electrode includes being electrically connected to each other in the capacitor deionizing instrument of the present embodimentAdsorption electrode piece 1 and collector 2, the outside of collector 2 is at least partly coated with water barrier 3, the periphery of water barrier 3 and absorptionElectrode slice 1 is tightly connected, thus by collector 2 and water segregation.Collector 2 may include metal or nonmetallic, such as collector 2It can be made of graphite powder or metal powder.Water barrier 3 and adsorption electrode piece 1 can be connected by 4 adhesion of adhesion agent or insertingIt connects.For example, adsorption electrode piece 1 is equipped with slot, one end of water barrier 3 adapted in slot, thus realize adsorption electrode piece 1 withThe inserting of water barrier 3 connects.
In the present embodiment, 2 part of collector exposes to water barrier 3, adsorption electrode piece 1 and this exposed part collector2 contacts are conductive and cover this exposed part collector 2,4 adhesion water barrier 3 of adhesion agent and adsorption electrode piece 1, thus by outerThis part collector 2 of dew is sealed between adsorption electrode piece 1 and water barrier 3.Wherein, water barrier 3 can be high molecule plasticFilm, adhesion agent 4 can be marine glue.
The wiring construction of electrode, as follows using principle in the capacitor deionizing instrument of the present embodiment.
Collector 2 is wrapped up come water proof by macromolecule plastic film, and macromolecule plastic film has some strength, certainUnder Electro Sorb operating voltage, film will not be damaged, or harmful substance is precipitated.In addition, 2 part of collector exposes to macromoleculePlastic film, adsorption electrode piece 1 contact conduction with this exposed part collector 2 and cover this exposed part collector 2,Marine glue adhesion water barrier 3 and adsorption electrode piece 1, thus by this exposed part collector 2 be sealed in adsorption electrode piece 1 and everyBetween water layer 3.Marine glue also functions to the effect of water proof.In this way, passing through the collective effect of macromolecule plastic film and marine glue, preventOnly collector 2 contacts water and electrochemical corrosion occurs.
