Description

The method and device thereof of atrament in a kind of abjection ardealite
Technical field
The invention belongs to phosphorous chemical industry field and ardealite comprehensive utilization techniques, and in particular to black in a kind of abjection ardealite The method and device thereof structure technology of substance.
Background technique
Phosphogypsum dihydrate is the industrial solid castoff excluded in dihydrate wet-process phosphoric acid production process, and main component is two H 2 O calcium sulphate (CaSO4·2H2O), in addition to this also containing a small amount of soluble P2O5, F, the harmful substances such as black organic matter.Phosphorus Organic matter in gypsum both increased building gypsum normal consistency water requirement, and the combination that can also weaken between dihydrate gypsum crystal makes firmly Change body porosity to improve, but intensity reduces, compression strength can be made to reduce about 15% 0.1% low content organic matter, Porosity increases by 9% (organic matter, eutectic phosphorus in the ardealite such as Peng Jiahui and its influence [J] construction material to performance Report, 2003 (3): 221-226).
By ardealite resource utilization, in addition to solubility P in ardealite to be eliminated2O5, F to the influence of ardealite outside, also Need to remove the atrament (organic matter) in ardealite.The method that major part technique is all made of flotation at present removes in ardealite Atrament (organic matter), it is possible to bring new impurity into, and floating agent price general charged is expensive, is unfavorable for industrialization and pushes away Extensively.Chinese patent CN105000585A is disclosed in a kind of ardealite and purification process technique, and this patent reports a kind of organic Trash eliminator, but the device separates organic matter by aeration mode, and treating capacity is small, and the ardealite upper layer after separation is also contained Partial organic matter, the organic matter isolated also contain a large amount of gypsum, are unfavorable for the resource utilization of ardealite.
Summary of the invention
The purpose of the present invention is to provide a kind of high degree of automation, process flow is simple, low energy consumption, gypsum utilization rate is high Removal ardealite in atrament method.
Experiment shows: the partial size of ardealite is different, and contained impurity and sinking speed is different.Partial size is in+400 purposes Ardealite, sinking speed are 2~5cm/min, and dihydrate gypsum content is greater than 85% in ardealite；Partial size is in -400 mesh~+600 mesh Ardealite, sinking speed is 0.5~1cm/min, and dihydrate gypsum content is greater than 80% in ardealite；Phosphorus of the partial size in -600 mesh Gypsum sinking speed is less than 0.3cm/min, and main component is the atrament containing organic matter in ardealite, and dihydrate gypsum content is small In 50%.It can be easily by the same of the atrament abjection in ardealite using the sinking speed difference of different-grain diameter ardealite When, ardealite is classified.
To achieve the above object, the present invention is achieved by following steps:
A kind of method of atrament in abjection ardealite, the invention is characterised in that, it is achieved by following steps:
A, it after ardealite is starched again, is classified to obtain the ardealite containing a large amount of atraments by two stages of hydrocyclones；
