Description

The rotating flow electrowinning plant of heavy metal in a kind of recycling slag
Technical field
The invention belongs to heavy metal resources utilization technology fields in abandoned mine slag, are related to a kind of for handling the rotation of slag Turn of tidal stream electrowinning plant.
Technical background
Heavy metal containing 1000ppm or more in the certain dump slags generated after ore smelting, these heavy metals can To carry out recycling and reusing.After actual technique generally uses the heavy metal in acid dissolution slag, recycled using the method for electrodeposition. But general Winning cell is to put one or more pairs of anode and cathode metal plates in rectangular pond to carry out energization recycling.Because electrolyte cannot fill It point is contacted with cathode plate, leads to that the not high heavy metal recovery rate of this Winning cell, metals content impurity height of recycling, energy consumption is high Problem.In addition also there is cartridge type turbulent flow electrodeposition equipment at present, improve the rate of recovery of heavy metal, but still not ideal enough.Therefore make Electrolyte is sufficiently and cathode contacts, the rate of recovery for increasing heavy metal are very necessary.
Summary of the invention
The rotating flow for being preferably used to handle heavy metal recovery in slag the purpose of the invention is to provide a kind of effect Electrowinning plant specifically adopts the following technical scheme that:
It is a kind of for handling the rotating flow electrowinning plant of slag, which is characterized in that include rotating flow Winning cell, cathode tube Heavy metal powder can be precipitated in body, cathode；Anode is located in the middle part of cathode cylinder, and anode uses square column Ni―Ti anode, cathode tube It include solution inlet port below body, top includes taphole.
The further technical solution of the present invention is, can make multiple electrodeposition equipment in parallel or series, can advanced treating containing a huge sum of money Belong to solution.
It using the present invention of technical solution as above, has the advantages that compared with the existing technology: increasing solution and yin The contact of pole improves the rate of recovery of heavy metal.Easy to operate, maintenance cost is low.Modularization is readily transported.
Detailed description of the invention
In order to further illustrate the present invention, it is illustrated with reference to the accompanying drawing:
Fig. 1 is the standby structural schematic diagram that rotating flow electrodeposition of the invention is set, including 1. plastic shells；2. inlet；3. going out Liquid mouth；4. cylinder cathode；5. square column Ni―Ti anode.
Fig. 2 is rotating flow Winning cell electrodeposition appearance schematic diagram of the present invention, including 1. square column Ni―Ti anodes；2. cartridge type is negative Pole；3. cylinder cathode top view.
Specific embodiment
The embodiment of the present invention is illustrated with reference to the accompanying drawing, embodiment is not construed as limiting the invention:
A kind of rotating flow electrowinning plant for heavy metal recovery in slag, which is characterized in that it include rotating flow Winning cell, Heavy metal powder can be precipitated in cathode cylinder, cathode；Anode is located in the middle part of cathode cylinder, and anode uses square column Ni―Ti anode, It include solution inlet port below cathode cylinder, top includes taphole；It is connected between solution inlet port and taphole by pipeline Winning cell.The technical effect and its realization process for the essence that the technical program is played are as follows: 30% sulphur is injected in slag Acid dissolves the Leaching of Heavy Metals in slag, leaches solid-to-liquid ratio 1: 3~1: 10,1~6h of extraction time, extraction temperature 10~50 DEG C, and be stirred, heavy metal ion is contained in solution.Liquid exports to filter, filters particles in solution, into rotating flow Electrowinning plant electrodeposition.100~1000A/m of current density2, electric effusion concentration of heavy metal ion≤10mg/L after processing, and return Into technique front end injection lysate.It is dry after remaining slag discharge, it is discharged according to environmental requirement, or for building Material production.
