The utility model discloses an evaporimeter, filter, cooling crystallizer tank, centrifugal filter and the mother liquor tank that connect gradually through the pipeline. The utility model discloses can be fast to rehenic acid ammonium solution purify, the crystallization operation, promote crystallization and removal impurity efficiency by a wide margin, ensure product quality, realize the through engineering approaches continuous production of rehenic acid ammonium simultaneously.
Description
Technical field
This utility model belongs to technical field of chemical, relates to a kind of rehenic acid ammonium purifying crystal system.
Background technology
Rhenium is that one is extremely rare and scattered metallic element, is worth higher, and in nature, the mineral of rhenium-containing are rare, how with trace content association in copper-molybdenum thing；In Copper making process, most rhenium enters in the acid washing water of chemical plant washing smoke section, in order to reclaim the rhenium in acid washing water, by the Ammonium rhenate solution that amine extractant direct extract and separate rhenium back extraction obtain concentration height, purity is high after generally first adopting sulfuration enrichment, enrichment slag to leach.
In rehenic acid ammonium product preparation process, liquid crystallisation by cooling after Ammonium rhenate solution elder generation evaporation and concentration, again insulation need to being filtered to remove insoluble matter, filtering and impurity removing, after leaching rehenic acid ammonium crystal, the rehenic acid ammonium crystal series of process process such as dry again, finally just can obtain qualified rehenic acid ammonium product；But, current Ammonium rhenate solution prepares the process of rehenic acid ammonium crystal, or segmentation carries out, and production efficiency is low, and insulation filtering and impurity removing effect is also undesirable, also useless realizes the continuous production operation of through engineering approaches.
Utility model content
The purpose of this utility model be for prior art Problems existing provide a kind of can through engineering approaches produce continuously, the good height of remove impurity refining effect and the high rehenic acid ammonium purifying crystal system of production efficiency.
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is:
A kind of rehenic acid ammonium purifying crystal system, including the vaporizer being sequentially connected with by pipeline, filter, crystallisation by cooling groove, filter centrifugal and mother liquor tank；
The liquid outlet of described mother liquor tank is connected to vaporizer by circulating pump；
Described filter centrifugal expects that outlet is connected to microwave dryer admittedly；
It is provided with agitating device in described crystallisation by cooling groove；
Pipeline between described vaporizer and filter, the pipeline between filter and crystallisation by cooling groove, the pipeline between crystallisation by cooling groove and filter centrifugal are provided with electrically-controlled valve.
This utility model has the advantages that
Ammonium rhenate solution can quickly be purified by this utility model, crystallization operation, crystallization and dust removal rate is substantially improved, it is ensured that product quality, and the through engineering approaches simultaneously realizing rehenic acid ammonium produces continuously.
Accompanying drawing explanation
Fig. 1 is system connection figure of the present utility model.
Detailed description of the invention
A kind of rehenic acid ammonium purifying crystal system as shown in Figure 1, including the vaporizer 1 being sequentially connected with by pipeline, filter 2, crystallisation by cooling groove 3, filter centrifugal 4 and mother liquor tank 5, the liquid outlet of described mother liquor tank 5 is connected to vaporizer 1 by circulating pump 6, described filter centrifugal 4 expects that outlet is connected to microwave dryer 7 admittedly, it is provided with agitating device 8 in described crystallisation by cooling groove 3, the pipeline between described vaporizer 1 and filter 2, the pipeline between filter 2 and crystallisation by cooling groove 3, pipeline between crystallisation by cooling groove 3 and filter centrifugal 4 are provided with electrically-controlled valve 9.
During work, Ammonium rhenate solution enters and is evaporated in vaporizer 1 purifying operation, the most of water evaporates in Ammonium rhenate solution is fallen, and in solution, partial impurities precipitates out simultaneously；After remove impurity is filtered in Ammonium rhenate solution entrance filter after evaporation purification, entering back into and carry out crystallisation by cooling operation in crystallisation by cooling groove 3, during crystallisation by cooling operation, the rehenic acid ammonium crystal in crystallisation by cooling groove 3 is stirred by agitating device 8, it is prevented that crystal lumps；Rehenic acid ammonium solidliquid mixture in crystallisation by cooling groove 3 enters in filter centrifugal 4 and carries out solid-liquid separation, rehenic acid ammonium crystal after separation is entered microwave dryer 7 heat drying by the solid material outlet of filter centrifugal 4, Ammonium rhenate solution after separation then enters in mother liquor tank 5 and stores, when the Ammonium rhenate solution in mother liquor tank 5 reaches a certain amount of, then Ammonium rhenate solution is squeezed into vaporizer 1 carried out purifying crystal operation by circulating pump 6.
