Feed liquid nature overflow discharge in reaction kettle, it is 8~16 hours to make the residence time of feed liquid in a kettle, obtains slurry；
(2) slurry is aged：Mixing speed is adjusted to 200rpm, keeps digestion time 6h~8h, make particle in slurry into
One step uniforms；
(3) slurry after ageing is input to filter device and is filtered washing, up to no by-product salt sodium sulphate residual, obtained
Slurry after to washing；
(4) slurry after washing is transferred to drying device, is crushed after 1~5 hour dry under the conditions of 50~200 DEG C, i.e.,
Ternary precursor particle is made.
Wherein, in above-mentioned steps (4), we are dried the slurry after washing generally use tray drier, do
A large amount of dust is will produce during dry to overflow from the offgas outlet of tray drier, since these dust size spans are big, and
It is less than 1 μm of ultra-fine grain containing a large amount of grain size, therefore is difficult to fully be filtered with bag filter, these ultra-fine grains
It is discharged into the waste for not only causing serious environmental pollution in air and causing resource.

Discharge port 10 is stated with reaction kettle to be connected.
It is proposed that the main component of dry exhaust particulate is the hydroxide particles of nickel cobalt manganese, therefore available sulfuric acid spray
The form of leaching is recycled, we first remove the larger hydroxide particles of degranulation with bag filter in the utility model, so
The hydroxide particles for using ultra-fine nickel cobalt manganese of the sulfuric acid spray column processing grain size less than 1 μm again afterwards, in sulfuric acid spray column, sulfuric acid
Sulfuric acid solution in solution reservoir is by being pumped into spray portion, and sulfuric acid is from tower top from top to bottom flow process, with nickel cobalt in tail gas
Manganese hydroxide precipitate small particles reactive absorption forms sulfuric acid metal salt solution.Matched again by being pumped into sulfuric acid metal salt solution
Sulfate starting material in raw material storage tank is sent into metal salt again at this time and prepares kettle by kettle processed, after being configured to required solution concentration,
It is finally sent into reaction kettle and participates in reaction.
Reaction kettle described in claim 1 is the reaction kettle prepared for slurry in background technology step (1).
The utility model has the beneficial effects that：1) hydroxide of ultra-fine nickel cobalt manganese of the high efficiente callback grain size less than 1 μm is realized
Composition granule；2) whole system reasonable design is closely connected with ternary precursor production system, is convenient for entire technology controlling and process, investment
It is at low cost.
