Abstract
The utility model relates to an electrolytic manganese passivation fluid recovery unit, it includes the casing, is provided with at the casing up end that the scavenging solution advances tub, blast pipe and waste liquid advance the pipe, lower terminal surface is provided with the fluid -discharge tube, the scavenging solution advances tub, the waste liquid advance the pipe respectively with set up the two liquid storage pots intercommunication in the casing, the liquid storage pot opposite face spreads all over the shower nozzle, is provided with adsorbed layer and filter layer in the liquid storage pot lower part. Because carry out above -mentioned technical scheme, this application can be rejected cr6+ in the waste liquid and cr3+ basically completely, the bichromate natrium of formation or dichromic acid potassium are recoverable repeated to be used as electrolytic manganese passivation liquid. Can greatly shorten the production technology step when this application is used, save the plenty of time, be favorable to the industrial production.
Description
Technical field
The utility model relates to a kind of electrolytic manganese passivating liquid retrieving arrangement.
Background technology
Pure manganese at home obtains and obtains mainly through electrolytic process, and the electrolytic manganese enterprise of more than 95% take manganese carbonate ore as raw material, and manganese processed is carried out in employing acidleach, double salt electrolysis process; Because the production technique of electrolytic manganese limits, can produce more Mn-bearing waste water in the production process of electrolytic manganese, this primary pollution source is wherein passivating wastewater, washes plate waste water, mill floor flushing waste water, filter cloth Cleaning Wastewater, sheet frame Cleaning Wastewater, clear groove waste water, slag storehouse percolate, plant area's rainwash, electrolyzer water coolant etc.
Electrolytic metal Mn is generally adopt polymeric adsorbent to remove the chromium ion in waste water in producing, but its adsorptive capacity is limited, needs to carry out regenerative operation and just can continue to use, make to produce and pause.
The application's correlation technique content has no disclosure.
Summary of the invention
The purpose of this utility model be to provide a kind of can the long-time electrolytic manganese passivating liquid retrieving arrangement that chromium ion in waste water is removed continuously.
The purpose of this utility model is achieved in that electrolytic manganese passivating liquid retrieving arrangement, it comprises housing, scavenging solution inlet pipe, vapor pipe and waste liquid inlet pipe is provided with in housing upper surface, lower surface is provided with liquid discharge pipe, scavenging solution inlet pipe, waste liquid inlet pipe are communicated with two container for storing liquids be arranged in housing respectively, container for storing liquid opposite face spreads all over shower nozzle, and container for storing liquid bottom is provided with adsorption layer and filtering layer.
Owing to carrying out technique scheme, Cr6+ and Cr3+ in waste liquid can reject by the application substantially completely, and the sodium dichromate 99 of generation or the recyclable repetition of potassium bichromate use as electrolytic manganese passivating liquid.In the application's application, step is less, and it can save the plenty of time, is conducive to suitability for industrialized production.After adsorption layer loses adsorptive power, continue to remove chromium ion by scavenging solution and rare precious metal coating, thus make to produce continuously.
Accompanying drawing explanation
Fig. 1 is electrolytic manganese passivating liquid retrieving arrangement structural representation.
Legend: 1, scavenging solution inlet pipe, 2, vapor pipe, 3, waste liquid inlet pipe, 4, housing, 5, shower nozzle, 6, container for storing liquid, 7, adsorption layer, 8, filtering layer, 9, Sptting plate, 10, liquid discharge pipe
Embodiment
The utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and practical situation.
Embodiment: electrolytic manganese passivating liquid retrieving arrangement it comprise housing, be provided with scavenging solution inlet pipe 1, vapor pipe 2 and waste liquid inlet pipe 3 in housing upper surface, lower surface is provided with liquid discharge pipe 10.Scavenging solution inlet pipe 1, waste liquid inlet pipe 3 are communicated with two container for storing liquids 6 be arranged in housing 4 respectively, and two container for storing liquids 6 are arranged on opposite side in housing 4, and container for storing liquid 6 opposite face spreads all over shower nozzle 5, and container for storing liquid 6 bottom is provided with adsorption layer 7 and filtering layer 8.
In the container for storing liquid 6 be communicated with scavenging solution inlet pipe 1, be filled with alkali lye, described alkali lye is NaOH or KOH solution.
Described adsorption layer is chromium ion polymeric adsorbent, and it is prior art, and concrete component is not described in detail.
Described container for storing liquid 6 is titanium metal tank, with rare precious metal coating on container for storing liquid 6 inwall.
Be provided with Sptting plate 9 between two container for storing liquids 6, its surface scribbles rare precious metal coating, and described Sptting plate 9 is waviness, and material is titanium plate, and chromium ion can adsorb by further.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
