Technical field
The utility model relates to waste reclaiming device technical field, particularly relates to a kind of sulfuric acid waste removal of impurities retrieving arrangement.
Background technology
Current industrial enterprise can produce a large amount of sulfuric acid waste, if sulfuric acid waste directly discharges, not only can make water body and soil acidification, work the mischief to ecotope, and waste ample resources.Have at present by the raw materials for production of sulfuric acid waste as bodied ferric sulfate, but containing heavy metal in sulfuric acid waste, if be directly used as to produce bodied ferric sulfate, the quality of polyaluminum sulfate iron product can be affected, therefore sulfuric acid waste is before for the production of bodied ferric sulfate, needs to carry out removal of impurities.
Utility model content
The purpose of this utility model there is provided a kind of sulfuric acid waste removal of impurities retrieving arrangement, removal of impurities can be carried out to sulfuric acid waste, sulfuric acid waste after removal of impurities can be used as the raw materials for production of bodied ferric sulfate, effectively reduce the heavy metal content in polyaluminum sulfate iron product, bodied ferric sulfate quality product is made to reach high-quality, the rare metal wherein contained can be recycled simultaneously, there is certain economic benefit, and extraction agent reusable edible, the layout of whole retrieving arrangement has saved the time of technique fully, cost is low, easy to operate, pollution-free.
The technical solution adopted in the utility model is as follows:
A kind of sulfuric acid waste removal of impurities retrieving arrangement, comprise waste liquid pool, extraction tank, spent acid basin, first rinse bath, reactor, second rinse bath, filter vat and pressure filter, sour pump is provided with between described waste liquid pool and extraction tank, described sour pump two ends connect waste liquid pool and extraction tank respectively by pipeline, and the sulfuric acid waste supernatant liquor of precipitated form in waste liquid pool is evacuated to extraction tank extracts, described extraction tank connects waste liquor storage tank and the first rinse bath respectively by pipeline, described first rinse bath ligation still, reactor connects filter vat and the second rinse bath respectively by pipeline, described filter vat connects pressure filter, second rinse bath connects extraction tank by pipeline.
Pipeline between the second described rinse bath and extraction tank is provided with control valve.
Described waste liquid pool is divided into two-layer up and down with coarse filtration plate, upper strata is settling tank, and lower floor is filtering basin, and settling tank avris is provided with sewage draining valve.
The pipeline of the sour pump of described connection waste liquid pool extends filtering basin bottom.
When the utility model uses, the sulfuric acid waste in waste liquid pool staticly settles, and supernatant liquor enters extraction tank by sour pump and extracts, and the removal of impurities spent acid after extraction enters spent acid basin, can be used as the raw materials for production of bodied ferric sulfate; What obtain after extraction enters the first rinse bath containing rare metal organic phase, by entering reactor after sulfuric acid scrubbing, back extraction is carried out with alkali lye in reactor, obtain strip liquor and waste liquid, strip liquor enters filter vat filtration and obtains impurity filtrate, then obtain filter cake by pressure filter press filtration, filter cake is recycled; Waste liquid enters the second rinse bath, and through sulfuric acid scrubbing, the extraction agent obtaining regenerating can cycling and reutilization.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Sulfuric acid waste removal of impurities retrieving arrangement of the present utility model, removal of impurities can be carried out to sulfuric acid waste, sulfuric acid waste after removal of impurities can be used as the raw materials for production of bodied ferric sulfate, effectively reduce the heavy metal content in polyaluminum sulfate iron product, bodied ferric sulfate quality product is made to reach high-quality, the rare metal wherein contained can be recycled simultaneously, there is certain economic benefit, and extraction agent reusable edible, the layout of whole retrieving arrangement has saved the time of technique fully, cost is low, easy to operate, does not produce pollution.
