Description
Technical field
This utility model relates to aluminium fluoride slurry sedimentation field, especially a kind of aluminium fluoride slurry subsider being capable of continuous operation.
Background technology
Aluminum fouoride, white anorthic crystal or powder. Relative density 2.882 (25 DEG C). It is insoluble in water, acid and aqueous slkali, insoluble in majority of organic solvent, is also insoluble in Fluohydric acid. and liquid hydrogen fluoride. Character is highly stable, with liquefied ammonia, even heat to still Fails To Respond of being fuming with concentrated sulphuric acid, unchanged with potassium hydroxide congruent melting, also not by hydrogen reducing, heating is not decomposed, but distillation. Sublimation temperature 1291 DEG C. At 300��400 DEG C, can be fluohydric acid gas and aluminium oxide by water vapour partial hydrolysis.
The hexafluosilicic acid method of aluminum fouoride: one, heat the silicate fluoride solution of 18% to about 78 DEG C, is subsequently adding in reactor and aluminium hydroxide generates aluminun fluoride solution 100 DEG C of reactions.
Two, aluminun fluoride solution is filtered to remove silicon dioxide. Filtrate is incubated 35 hours at 90 DEG C, generates the mixed solution containing aluminum fluoride trihydrate (AlF3 3H2O) crystallization.
Three, reaction slurry is filtered to isolate aluminum fluoride trihydrate crystallization (moisture 5%). Successively through twice drying and dehydrating, first time controls to dry temperature 205 DEG C to remove big portion water, makes the total moisture content of aluminum fluoride trihydrate be down to about 6% from 45%, and second time controls to dry temperature 590 600 DEG C to slough remaining water. Cooled and the prepared aluminum fouoride product of material after dehydration.
The shortcoming of this technology: one, reaction slurry filtering and dewatering process is low by pulp density, in slip, solid formation content is few, the different filter type of employing is filtered all existing and filters substantial amounts of slip and solid formation amount is few, filter load does not reach setting requirement, design must take into filter area when filtering big, and equipment investment is big. And solid formation content is low in slip, filtering and do not do, filter efficiency declines. Two, aluminium fluoride slip sedimentation concentration, after the sedimentation of simple subsider, aluminum fluoride crystal can be deposited on bottom subsider, it is necessary to adopting the way of labor cleaning to clear up, operation labor intensity is big.
In sum, the density of aluminium fluoride slurry is low, solid concentration is low, substantial amounts of for liquid phase (saturated mother solution), by the impact of slip physical property in carrying out solid-liquid separation process, adopting the mode that vacuum filters or other conscience filters all to deposit the big load that filters to decline, filter process is low by solid thing content, filters and does not do. The way adopting natural subsidence concentration can realize increasing the solid content in aluminium fluoride slip, the water content of material after improving filter efficiency and ensureing filtration, but adopt the way of natural subsidence concentration, material can be deposited bottom subsider, mode that must be artificial is cleared up, the work shortcoming that seriality is not quite satisfactory and labor intensity is big.
