Description

A kind of electrolyzer

Technical field

The utility model relates to a kind of electrolyzer, and it can be in order to reclaim the cupric ion contained in paper tinsel water or the waste water of washing that produces in the Copper Foil production process, in order to substitute existing iron powder replacement pond of using.

Background technology

The production process of Copper Foil mainly is divided into four operations: dissolve copper → life paper tinsel → aftertreatment → go-on-go.Water station is given birth to paper tinsel in utilization, aftertreatment is washed paper tinsel water and prepared in the pure water process through more medium filter, r-o-, mixed bed, and can produce 120-150m every day ³, the copper-containing wastewater about concentration 2g/l.In order to reclaim the copper in the waste water, increase the performance of enterprises, generally adopt the method for iron powder replacement to reclaim copper, this operation is carried out in the iron powder replacement pond.The structure in iron powder replacement pond is seen Fig. 1, and copper-containing solution is after import 1 gets into displacement pool 2, along the sign flow direction outlet 3 of arrow.The polylith iron plate 4 that place both sides about in the displacement pool 2 can also cement out the cupric ion in the solution in the flow of solution process except the flow direction in order to restriction solution, and the solid-state copper that cements out is deposited in the displacement pool 2.Adopt the recovery of this method copper lower, the copper sponge of producing gained is not high because of the many prices of foreign matter content.

Investigate demonstration through test and find to use extraction-electrolysis process to substitute existing iron powder replacement method, can effectively improve the recovery of copper.Be specially: extract the most copper in the copper-containing wastewater of the concentration 2g/l left and right sides with extraction agent earlier, obtain the extraction liquid of cupric concentration at 30-40g/l; And then the employing electrolysis process, on negative plate, the electrolytic copper purity that obtains like this can directly add copper dissolving tank and use up to 99.8% the use electrolyzer the copper ions galvanic deposit in the gained extraction liquid.

The utility model content

The utility model purpose is to provide a kind of electrolyzer, uses this electrolyzer can be the cupric ion galvanic deposit in the extraction liquid on negative plate, and the electrolytic copper purity that obtains like this can directly add copper dissolving tank and use up to 99.8%.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of electrolyzer comprises anode and negative electrode, wherein; Said anodic structure is made up of a plurality of positive plates that are arranged in parallel, and the structure of said negative electrode is made up of a plurality of negative plates that are arranged in parallel, and yin, yang pole plate spaced and parallel is arranged; Anode links to each other with positive source, and negative electrode links to each other with power cathode.

Concrete, each positive plate of said anodic all links to each other with positive source, and each negative plate of said negative electrode all links to each other with power cathode.The number of positive plate and maximum cross-section area equate with negative plate, are beneficial to form uniform electric field.In actual production process, can come suitably to select the number of yin, yang pole plate, the area and the direct supply size of maximum cross-section according to the speed of separating out of copper on the negative plate.This electrolyzer can use stereotype as anode, and copper coin is as negative electrode; Redox equation in its electrolytic process is: 2CuSO ₄+ 2H ₂O → 2Cu+2H ₂SO ₄+ O ₂↑.

Compare the advantage of the utility model with prior art:

The said electrolyzer cathode-anode plate of the utility model is spaced, and is beneficial to the amount of separating out that improves copper in the unit time.This groove is used for the recovery of extraction liquid cupric ion, and recovery height and purity are high, and the copper of on negative plate, separating out recovery can directly supply to produce and use.By 98% measuring and calculating of the dense water yield of the present production recovery, every day, recyclable finished product copper was more than 240 kilogram, ton surplus year recyclable copper 86.4, and by 60,000 yuan of copper prices per ton, 2000 yuan of calculating of cost year are estimated surplus the benefit 500 ten thousand yuan, than adopting the iron powder replacement pond to reclaim

Increase by 1,600,000 yuan of benefits.

Embodiment

Below in conjunction with accompanying drawing the utility model is explained further details, but the protection domain of the utility model is not limited thereto.

As shown in Figure 2, a kind of electrolyzer 9 comprises anode and negative electrode, and wherein, said anodic structure is made up of six positive plates that are arranged in parallel 5, and the structure of said negative electrode is made up of six negative plates that are arranged in parallel 6, and negative plate 6 is spaced with positive plate 5.Each positive plate 5 of said anodic all links to each other with positive source 7, and each negative plate 6 of said negative electrode all links to each other with power cathode 8.The number of positive plate and maximum cross-section area equate with negative plate.This electrolyzer 9 uses stereotype as anode, and copper coin is as negative electrode.

During use, change cupric extraction liquid liquid in the electrolyzer 9 over to earlier, open direct supply then and just can carry out electrolysis, the cupric ion in the solution does not stop to separate out from the copper coin of negative electrode.Concrete, for example the yin, yang pole plate can adopt each 26 block gap to be arranged in parallel aborning, and the area of plate maximum cross-section is 1m * 0.8m, and direct supply adopts about 12V (2000A), can deposit the copper of 0.7-0.8 ton behind the two weeks on the copper coin of negative electrode.The electrolytic copper purity that obtains like this can directly add copper dissolving tank and use up to 99.8%.

It should be noted last that: above embodiment only is illustrative rather than definitive thereof the technical scheme of the utility model; Any modification that the utility model is carried out perhaps is equal to replacement; And any modification or the local replacement that do not break away from the utility model spirit and scope, it all should be encompassed in the middle of the claim scope of the utility model.
