Technical field

The utility model relates to a kind of metallurgical waste retrieving arrangement, relates in particular to the retrieving arrangement of solution in a kind of hydrometallurgy filter residue.

Background technology

Current electrolytic manganese industry is in system liquid process, liquid content is generally 25-30% in the filter residue, manganous sulfate content is on average at 110g/L in the solution, ammonium sulfate content is on average at 125g/L, is to set up the slag storehouse of special stacking manganese slag according to State Environmental Protection Administration's " cleaner production standard electrolytic manganese industry " to present processing mode, solubility salt in the manganese slag pollutes water body and still is difficult to solve, so only the slag water ratio is claimed in the standard.And this part filter residue is not used and directly is discharged to the slag storehouse at present, so not only wastes resource, and contaminate environment.In order to utilize resource, generally adopt the method for barrier film supercharging to reduce the content of solution in the filter residue or take in pressure filter the method for backwash to wash.The former extrudes wherein part moisture content by supercharging, but still also contains 25% moisture content; Defectives such as though the latter has certain effect by washing, exists rinsing inhomogeneous, and the solute that washes out is limited.

Summary of the invention

At above-mentioned situation, the purpose of this utility model provides a kind of retrieving arrangement that is used for hydrometallurgy filter residue solution, it can be from existing depleted slag liquid useful rare metal such as reclaim(ed) sulfuric acid manganese, can improve the environmental pollution of system manganese industry again.

For achieving the above object, a kind of retrieving arrangement that is used for hydrometallurgy filter residue solution, it comprises that two-way reclaims the circulation link, one the tunnel reclaims endless chain route chemical combination pond, pressure filter, gauger, disperse the pond, washing tower, waterworks and band filter are formed, two the tunnel reclaim endless chain route chemical combination pond, the pressure filter treating pond, electrolyzer and cooling tower) form, two-way reclaims configurable number platform pump in the circulation link, described one the tunnel reclaims also to be included in the circulation link between washing tower and the chemical combination pond and is connected in series a medial launder a, described two the tunnel reclaim also to be included in the circulation links between electrolyzer and the cooling tower and are connected in series a medial launder b and a storage tank, be provided with the insulation cooling tube in the electrolyzer, be provided with distribution pipe in the described washing tower, it is by the top large cylinder, the big circular cone tube in middle part, the little cylinder in bottom, bottom conicle tube is formed.

For implementation structure optimization, its further step also has:

Washing tower is reverse-flow continuous washing tower.

The utility model adopts two-way to reclaim the circulation link, and the technical scheme of reclaim(ed) sulfuric acid manganese and ammonium sulfate from hydrometallurgy filter residue solution has overcome the defective that has the serious wasting of resources and environmental pollution in the existing filter residue treatment process.

The beneficial effect that the utility model is produced compared to existing technology:

(1) adopts two-way to reclaim the circulation link, realize recovered in high yields useful metal ion; (2) adopt the countercurrent washing measure, make that solution is fully recycled in the filter residue; (3) apparatus structure is simple, and processing ease is easy to maintenance, need not drop into more new equipment; (4) adopt the cooling tower refrigeration cycle, useful solution in the filter residue is concentrated recovery, saved resource, strengthened environment protection; (5) adopt reverse-flow continuous washing tower to carry out abundant rinsing, the useful solution of the overwhelming majority can be able to repetitive scrubbing and reclaim, and cost is very low, can reach the double effects of resources conservation and environmental protection.

The utility model mainly is fit to the recovery of useful component in the filter residue in the electrolytic metal industry system liquid process.

Below in conjunction with drawings and Examples the utility model is further described.
