It could be discharged after evilization processing, this will bring processing cost cost.Meanwhile also increasing usage amount and the buying of new hydrofluoric acid
Amount, that is, increase buying expenses cost.
So, if it is possible to acid solution and white flock precipitate are separated, for example, by certain filter device detach acid solution and
White flock precipitate, so that it may to re-use the acid solution, will just substantially reduce production cost.
But the white flock precipitate in acid solution, it will solidify after a long time, like glass bits, viscosity also compares
Larger, if only using simple sock filtration, that just needs manually to clean entire pipeline daily, and replaces filter bag.Consider
To contact of the acid solution in artificial cleaning may caused by it is dangerous, also, in view of filter bag needs regularly replace, this
Increase buying expenses cost.Importantly, also cannot achieve the harmless treatment of a large amount of acid solutions at present.
Certainly, there are also a kind of by the way of natural sedimentation, exactly acid solution is stored in big jar, allow its from
So precipitation, then takes supernatant liquor, is reused.This mode, it is clear that efficiency is very low, and needs to occupy prodigious
Storage tank space.
Therefore, the existing technology needs to be improved and developed.
