Abstract

The invention discloses an ultrahigh-current-density concurrent flow electrolytic bath and a solution inlet device thereof. Researches find that convective motion of electrolyte solutions is generated in a gap among every two adjacent anode plates and corresponding cathode plates, and spouts of corresponding nozzles are limited within the range 9 mm near the metal depositional planes of the cathode plates so that liquid flow sprayed out of the nozzles can be tightly attached to the metal depositional planes of the cathode plates in a parallel manner. The liquid flow sprayed out of the nozzles moves from bottom to top, is consistent with the electrolyte solutions in the rising direction, and does not cause a negative effect on settling of the anode plates, so that settling anode mud settles quickly, the anode mud content and the turbidity of the electrolyte solutions are reduced, vicious circle between concentration polarization and prior electrolyte solutions degenerated due to pollution is weakened, and therefore favorable conditions are created for further improving the current density of electrolytic refining, and ultrahigh-current-density electrolytic refining can be realized.

The invention provides a kind of feeding device of superhigh-current-density parallel-flow electrolyzer, electrolyzer comprises cell body 1, feeding device, liquid discharge device, some pieces of positive plates 3 and some pieces of negative plates 4.

Some pieces of positive plates 3 and some pieces of negative plates 4 are all overlapped on the upper edge of the two sides cell wall on cell body 1 length direction, and some pieces of positive plates 3 and some pieces of negative plates 4 are alternately arranged and many one piece and control outermost pole plate in cell body 1 and be positive plate 3 of the quantity of the number ratio negative plate 4 of positive plate 3 in cell body 1.

Feeding device comprises the first feed liquor assembly 2, first feed liquor assembly 2 comprises the first liquid-inlet pipe 201, first sparge pipe 202 and several be arranged on sparge pipe, for the nozzle 203 to jet electrolytic liquid in cell body 1, the fluid inlet of the first liquid-inlet pipe 201 is communicated with to supply electrolytic solution to the first liquid-inlet pipe 201 with electrolytic solution liquid feed device, the liquid outlet of the first liquid-inlet pipe 201 is communicated with the fluid inlet of the first sparge pipe 202, first sparge pipe 202 is fixedly installed on the bottom of the medial surface cell wall on cell body 1 length direction or the inner bottom surface cell wall of cell body 1, any one nozzle 203 all corresponding to the gap between adjacent positive plate 3 and negative plate 4 for adjacent two blocks of gap jet electrolytic liquid between positive plate 3 and negative plate 4.

Spout corresponding to the nozzle 203 in the gap between adjacent anode plate 3 and negative plate 4 is positioned within the vertical plane vertical range 9mm at metal depositional plane place of negative plate 4.Suppose a plane, this plane parallel in negative plate 4 metal depositional plane and be 9mm with the vertical range of the metal depositional plane of negative plate 4, control the spout of the nozzle 203 corresponding to gap between adjacent anode plate 3 and negative plate 4 in the gap between the vertical plane and this hypothesis plane at the metal depositional plane place of negative plate 4.Preferably, the spout corresponding to the nozzle 203 in the gap between adjacent anode plate 3 and negative plate 4 is positioned within the vertical plane vertical range 6mm at metal depositional plane place of negative plate 4.Above-mentioned metal depositional plane is two length and width sides of negative plate 4.The spout of nozzle 203 is the mouth spray of nozzle 203.

Liquid discharge device comprises liquid outlet, and liquid outlet is communicated with electrolytic solution device for storing liquid and refluxes for by the electrolytic solution in cell body 1.

The feeding device of superhigh-current-density parallel-flow electrolyzer provided by the invention, is not only applicable to the electrorefining of copper anode plate, is equally applicable to the metal that other adopts the technique purification metal target of electrorefining positive plate, such as metallic nickel, etc.Above-mentioned metal depositional plane is two length and width sides of negative plate 4.

At present, in actual production, mostly the Recycle design of electrolytic solution is bottom in and top out, electrolytic solution enters from the bottom of electrolyzer, flows out, apparently from the top of electrolyzer, in above-mentioned Recycle design, electrolytic solution mainly motion from the bottom up, just in time contrary with the direction of motion from top to bottom of the sedimentation anode sludge, pole is unfavorable for the sedimentation of the sedimentation anode sludge.The sedimentation anode sludge can not sedimentation quickly and smoothly, can flow everywhere on cell body 1 width, length direction and above-below direction along with electrolytic solution turbulent flow, poke one's nose everywhere, pollute the electrolytic solution in cell body 1, improve the opacity of anode sludge content in electrolytic solution and electrolytic solution, apparently, contaminated, muddy electrolytic solution is unfavorable for the electrorefining realizing superhigh-current-density certainly; The sedimentation anode sludge of rationally sedimentation does not change the proterties of electrolytic solution, easy generation concentration polarization, then the two is mutually promoted, form vicious cycle, exacerbate the degree of not rationally sedimentation and concentration polarization further, bath voltage is significantly raised and the significantly reduction of electricity effect, improve energy consumption and production cost, make negative plate 4 to be separated out the metal that should not separate out, reduce the purity of cathode copper, serious concentration polarization makes to need to reduce current density further, is unfavorable for the electrorefining realizing superhigh-current-density.

For this reason, industry technology personnel propose a kind of new circulation of elecrolyte mode, upper entering and lower leaving, electrolytic solution enters from the top of electrolyzer, flow out from the bottom of electrolyzer, in this Recycle design, electrolytic solution mainly motion from top to bottom, consistent with the direction of motion from top to bottom of the sedimentation anode sludge, be conducive to the sedimentation of the sedimentation anode sludge.But the concrete effect of the new Recycle design of this upper entering and lower leaving need further confirmation; Further, the annual production of the spreader for electrolytic cathode copper of China is at about 8,000,000 tons, and wherein the spreader for electrolytic cathode copper of every 200,000 tons needs the electrolyzer of about 720 (smelting enterprise is according to the production technique of oneself, the dress plate quantity slightly difference of electrolyzer, the electrolyzer quantity of equal production volume is made also to have difference a little), namely the annual production of 8,000,000 tons needs the electrolyzer of about 28800,28800 electrolyzers is all replaced with the Recycle design of upper entering and lower leaving, obviously unrealistic; Moreover at present, the Recycle design of electrolyzer many employings bottom in and top out, existence namely rationally, although adopt the Recycle design of bottom in and top out to be unfavorable for the sedimentation of the sedimentation anode sludge, exists the more favourable factor of electrorefining processes or condition in other place certainly.

After adopting the technical scheme in the present invention, efficiently solve the Recycle design of bottom in and top out and the problem of the sedimentation anode sludge: the present invention finds after deliberation, along with the carrying out of electrorefining processes, in electrolyzer, cupric ion in the electrolytic solution of the near surface of positive plate 3 length and width side and other metal ion content increase gradually, more and more higher compared to the content of firm cupric ion and other metal ion from the electrolytic solution that nozzle 203 sprays, it is increasing that its proportion becomes, and the cupric ion in the electrolytic solution of the near surface of aspectant negative plate 4 length and width side, above-mentioned positive plate 3 length and width side reduces gradually with other metal ion content, more and more lower compared to the content of firm cupric ion and other metal ion from the electrolytic solution that nozzle 203 sprays, it is more and more less that its proportion becomes, thus, the upward movement of electrolytic solution is being there is near negative plate 4 length and width side, the descending motion of electrolytic solution is being there is near positive plate 3 length and width side, thus the convective motion of the liquid that produces electrolysis in adjacent two pieces of gaps between positive plate 3 and negative plate 4, and through measuring, the maximum net thickness making the electrolytic solution liquid stream of upward movement near negative plate 4 length and width side is 9mm.The sedimentation anode sludge is that positive plate 3 produces in electrolytic dissolution process, and it is separated out from positive plate 3 surface, is enriched in the electrolytic solution of positive plate 3 near surface, then spreads in a cell along with electrolyte flow during beginning.The present invention makes full use of the convective motion of this electrolytic solution, within the scope of 9mm near the metal depositional plane spout of corresponding nozzle 203 being limited in negative plate 4, the liquid stream that nozzle 203 is sprayed is parallel with the metal depositional plane of negative plate 4, the liquid stream that nozzle 203 is sprayed and the metal depositional plane of negative plate 4 are close to, the liquid stream that nozzle 203 sprays moves from the bottom up, with the upward movement of the electrolytic solution of negative plate 4 near surface, direction is consistent, the liquid stream that nozzle 203 sprays is away from the descending motion of electrolytic solution of positive plate 3 surface and positive plate 3 near surface, the anode sludge that is enriched in positive plate 3 surface is swept along by the electrolytic solution of this descending motion and is moved downward, realize sedimentation smoothly, the liquid stream that nozzle 203 sprays can not the sedimentation of antianode mud cause negative influence, thus the Recycle design thoroughly solving electrolytic solution bottom in and top out is unfavorable for the problem of sedimentation anode slime, make the sedimentation anode sludge can rapid subsidence, can not along with electrolytic solution turbulent flow be at cell body 1 width as original, length direction and above-below direction flow everywhere, poke one's nose everywhere, reduce the opacity of anode sludge content in electrolytic solution and electrolytic solution, reduce original electrolytic solution of contaminated sex change and the vicious cycle of concentration polarization, improve the purity of electrolytic solution, electrorefining can be carried out in purer electrolytic solution, thus be that the current density improving electrorefining further creates favourable condition, be conducive to the electrorefining realizing superhigh-current-density.

In the present invention, apparently, the plane of above-mentioned hypothesis does not exist in actual production, and hypothesis exists this plane herein, just for convenience of description, is convenient to understand, should not becomes limiting the scope of the invention.
