Abstract

The utility model provides an electrolyte circulating system which comprises electrobaths, an electrolyte circulating tank and a circulating pump. A waste electrolyte which flows out of the electrobaths enters the electrolyte circulating tank. The electrolyte circulating tank is internally provided with a mixer of a new electrolyte and an old electrolyte. The waste electrolyte which flows into the circulating tank is mixed with a new electrolyte which flows into the mixer of a new electrolyte and an old electrolyte. The circulating pump is used for delivering the mixture of the waste electrolyte and the new electrolyte into the electrobaths. According to the electrolyte circulating system, the equipment investment and the circulating energy consumption are reduced, thereby realizing more uniform distribution of the electrolytes in the electrobaths and among the electrobaths.

Description

A kind of electrolyte circulation system

Technical field

The utility model relates to field of metallurgy, relates in particular to a kind of electrolyte circulation system.

Background technology

At present, electrolytic zinc industry generally is employed in electrolyzer one end liquid level top feed liquor, the liquid in-out Recycle design of fluid under the other end liquid.This mode is difficult to realize getting into solution uniform distribution in electrolyzer of electrolyzer; For avoid in the electrolyzer and between electrolyzer in the electrolytic solution zinc concentration difference not excessive, have to adopt a bigger circulation tank, make the new liquid of electrolysis in circulation tank with the electrolysis waste solution thorough mixing after; Squeeze into a surge tank again; To each electrolyzer feed liquor, an electrolysis waste solution part gets into circulation tank through the feed flow chute, and a part gets into the tail washings jar.This mode has following deficiency: facility investment is big, and circulation tank, tail washings jar, surge tank and feed flow chute need be set; Internal circulating load is excessive, and a large amount of waste liquids need return electrolyzer again, cause the recycle pump energy consumption big.

Summary of the invention

The purpose of the utility model provides a kind of electrolyte circulation system, reduces facility investment and circulating consumption, realizes that electrolytic solution distributes in electrolyzer and between electrolyzer more uniformly.

In order to solve the problems of the technologies described above, the electrolyte circulation system that the utility model provides is achieved in that

A kind of electrolyte circulation system comprises: electrolyzer, circulation of elecrolyte jar and recycle pump; Effusive electrolysis waste solution enters into said circulation of elecrolyte jar in the said electrolyzer; Be provided with new and old liquid mixer in the said circulation of elecrolyte jar, the electrolysis waste solution that flows in the circulation tank is mixed with the new liquid of electrolysis in the new and old liquid mixer of inflow; Said recycle pump is sent to said electrolyzer with the mixture of said electrolysis waste solution and the new liquid of electrolysis.

Optional; Said electrolyzer comprises: liquid-inlet pipe and overflow canal; Said liquid-inlet pipe extends to the bottom of said electrolyzer from said upper part of the electrolytic cell, and said liquid-inlet pipe 10mm place under electrolysis liquid surface has equalizing port, and said liquid-inlet pipe is drilled with liquid outlet in said bottom of electrolytic tank, negative plate position; Said overflow canal is around said electrolyzer, and the electrolysis waste solution in the said electrolyzer is discharged into said circulation of elecrolyte jar through said overflow canal.

The electrolyte circulation system that the utility model provides; The liquid outlet of liquid-inlet pipe is positioned at bottom, each negative plate below of electrolyzer in the electrolyzer; Solution in the entering electrolyzer has only through the tank room between each cathode-anode plate just can enter the overflow canal; Thereby realized getting into the solution uniform distribution in each tank room in the electrolyzer, helped near the ionic diffusion of negative electrode, reduced concentration polarization; And the equalizing port that is provided with on each electrolyzer liquid-inlet pipe not only can play the fluid exhaust but also the effect that weakens electrolyte column pressure is arranged, and it is sensitiveer, more even to make each concentrated flow amount adjust.

Further, because the effect of new and old liquid mixer makes new liquid of electrolysis and electrolysis tail washings directly send into electrolyzer through recycle pump behind the thorough mixing by a certain percentage, need not to be provided with surge tank and feed flow chute.When having guaranteed the requirement of lasting electrolysis, reduced unnecessary internal circulating load, the circulating consumption when having reduced facility investment and production to new liquid.The electrolysis tail washings directly returns circulation tank, discharges electrolyte system with the waste liquid riser on the direct self-circulation jar of the tail washings of new liquid equivalent, need not to be provided with the tail washings jar, saves space and facility investment.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, electrolyte circulation system comprises: electrolyzer 12, circulation of elecrolyte jar 6 and recycle pump 13; Effusive electrolysis waste solution enters into circulation of elecrolyte jar 6 in the electrolyzer 12; The new flow of electrolysis go into new and old liquid mixer 7 and in mixing tank 7 with flow into circulation tank 6 in electrolysis waste solution mix; Recycle pump 14 is sent to electrolyzer 12 with the mixture of electrolysis waste solution and the new liquid of electrolysis.

Wherein, Electrolyzer comprises: liquid-inlet pipe 4 and overflow canal 1; Liquid-inlet pipe 4 extends to the bottom of electrolyzer from electrolyzer 12 tops, liquid-inlet pipe 4 10mm place under electrolysis liquid surface has equalizing port 10, and liquid-inlet pipe 4 is drilled with liquid outlet 11 in electrolyzer 12 bottoms, negative plate position; Overflow canal 1 is around electrolyzer 12, and the electrolysis waste solution in the electrolyzer 12 is discharged into electrolyte circulation means 13 through overflow canal 1.Be provided with sewage draining exit 2 and drain hole 3 in electrolyzer 12 bottoms.

Wherein, be provided with new and old liquid mixer 7 in the circulation of elecrolyte jar 6; New and old liquid mixer 7 mixes electrolysis waste solution and the new liquid of electrolysis; The mixture of electrolysis waste solution and the new liquid of electrolysis is sent in the electrolyzer 12 by recycle pump 14 through mixture outlet 9; Have electrolysis waste solution riser 8 on the circulation tank 6, discharge electrolyte circulation system through riser 8 with the waste liquid of new liquid equivalent.
