In recent years, both at home and abroad to lithium carbonate product quality requirement more and more higher, and primary product all do not reach requirement mostly,
So research lithium carbonate purification is necessary.At present, the purification process of pure Lithium Carbonate product is prepared by thick level lithium carbonate product
Mainly there are causticizing process, recrystallization method, electrolysis, the hydrogenation precipitation method and hydrogenative decomposition method.Causticizing process can effectively remove deliming, magnesium
Ion, but need the milk of lime of high-purity；Recrystallization method is simple and easy to apply, but lithium carbonate solubility very little, and the production cycle is long, energy
Consumption is high；The lithium carbonate product purity that electrolysis is obtained is high and technique is simple, but the higher power consumptions of requirement of the method to film
Compare high；The hydrogenation precipitation method can better control over product granularity, but in preparation process to the purity requirement of lithium hydroxide very
Height, this just increases production cost：Hydrogenative decomposition method has higher operation possibility, and the rate of recovery is high, and common use should at present
Technique.
But, conventional lithium carbonate carbonic acid hydrogenation consersion unit has that mass transfer is poor, the reaction time, has a strong impact on
The production capacity of pure Lithium Carbonate.Meanwhile, in the case of directly blasting great amount of carbon dioxide, normal pressure carbon dioxide one way absorption efficiency
Low, recycling needs to consume a large amount of energy consumptions.
Utility model content
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and it is anti-to provide a kind of lithium carbonate carbonic acid hydrogenation
Device is answered, using press device, is kept under certain pressure, the one way absorption efficiency of carbon dioxide is high.Use simultaneously self-priming
Agitator, is conducive to sucking unreacted carbon dioxide in liquid, continues to participate in reaction, further improves turning for carbon dioxide
Rate, improves the carbonic acid hydrogenation rate of lithium carbonate.
The purpose of this utility model is completed by following technical solution.This lithium carbonate carbonic acid hydrogenation dress
Put, mainly include carbonic acid hydrogenation reaction cauldron and self-absorbing type stirrer, self-absorbing type stirrer is arranged on carbonic acid hydrogenation reaction cauldron center
Heat exchange pipeline is included in position, carbonic acid hydrogenation reaction cauldron, for controlling reactor internal temperature, carbonic acid hydrogenation reaction cauldron top bag
Carbonated import, carbon dioxide outlet, material inlet and temperature, pressure table, bottom include discharge port, and reactor inwall has
Hydraulic barrier；Carbon dioxide inlet extends vertically up to the bottom of carbonic acid hydrogenation reaction cauldron, and entrance location is arranged on hydraulic barrier bottom
The lower section of plane, hydraulic barrier is arranged on the inwall between the import and export of heat exchange pipeline.
Described self-absorbing type stirrer is made up of airway tube and self-priming agitating paddle, gas of the airway tube ullage in kettle
Below body suction liquid level, then gas is distributed in liquid by self-priming agitating paddle, reaction is continued to participate in.
The entrance location of described carbon dioxide inlet be arranged on hydraulic barrier baseplane and airway tube port plane it
Between.
The beneficial effects of the utility model are：The mass-transfer efficiency of gas-liquid two-phase is enhanced, shortens the reaction time.Meanwhile, it is single
The secondary carbon dioxide absorption efficiency high being passed through, gas circulation amount is few, reduces carbon dioxide recycle energy consumption.
