Description
Technical field
This utility model relates to box extraction tank apparatus field, is specifically related to a kind of novel box type oxidation-extraction groove.
Background technology
Box extraction tank is one of rare earth and some rare metals capital equipment in hydrometallurgy process, it is common that by
Mixing chamber clarifying chamber two parts composition, belongs to contact mass transfer apparatus step by step, equipped with agitator in mixing chamber, in order to liquid-liquid
Uniformly mixing, clarifying chamber is the empty room that cavity volume is bigger, in order to mixed liquid-liquid static layering.Want according to isolation technics
Ask extraction tank can use with single-stage, it is possible to the realization adverse current that is together in series, shunting mode are applied in combination.By liquid-liquid extraction or
In extraction process, add some chemical reagent change the chemical property being extracted material, to reach to improve product purity and extraction
Take the purpose of efficiency.
An important Technology is had, both: first converted by the valence state oxidant of cerium during extracting high-purity cerium
For the quadrivalent cerium of high-valence state, because the rare earth ion of quadrivalent cerium and trivalent has bigger separation, extracting, progression is the shortest
Under the conditions of can extract high-purity cerium dioxide smoothly, for extract highly purified cerium oxide create the strongest condition.According to biography
The operational approach of the feed liquid oxidation technology of system is: the solution being extracted material uses the oxidation of monomer tank, disposable by theoretical amount
Adding oxidant, carrying out chemical method oxidation (or reduction) every batch of material liquid is 8-10M3/ tank, then pumps into gravity tank by this tank feed liquid
In, at the uniform velocity enter in extraction tank by the flow of extraction process requirement and mix, reach the mass transport process of liquid-liquid extraction, this
The stability of feed liquid oxygenation efficiency is had a very big impact by intermittent operation method, and the extraction yield directly resulting in cerium is not enough, yield
The problem such as the highest, because being the manual operations of monomer tank, to the particular number adding oxidant, control is inaccurate, cause oxygenation efficiency not enough
Or oxidant excess, more importantly the use cycle of every tank feed liquid is generally about 2 days, has partial oxidation during this period
Agent generation chemical reaction and generate precipitate, extraction process is brought the biggest impact by this partly precipitated thing, can cause time serious
Stop production clear tank, clear groove.
If using small-sized monomer tank dispensing instead, asking all can occur in the concordance etc. of its equipment taken, personnel, place and feed liquid
Topic, can make cost increase, and yield declines.The best approach solving the problems referred to above is to ensure that the feed liquid entering extraction tank is fresh
Oxidized feed liquid, oxidized rear use between 12 hours is advisable, and oxidant precipitation otherwise can occur, have result of study
Showing, potassium permanganate can be oxidized to quadrivalent cerium trivalent cerium effectively in acid condition, but permanganic acid in extraction process
Root can be extracted in organic facies prior to quadrivalent cerium, thus loses oxidability, also reduces the loading capacity of extractant simultaneously.
In sum, it is necessary to solving potassium permanganate can not disposably add in pan feeding, but should add by graded quantitative, and
It is ensured of fresh oxidized feed liquid, the most orderly the carrying out of extraction process could be realized.
