Embodiment 1

[0063] Such as Figure 1 to Figure 8 Shown, titanium white slurry produces metatitanic acid production method, and this method comprises the following steps:

[0064] A. Dilution: Put 700Kg of purchased titanium dioxide slurry into the washing tank 6, start the stirring device 7, open the water inlet valve 29, add 10 tons of water, and stir for 10 minutes;

[0065] B. Alkali addition reaction: open the lye valve 25 and add 30% NaOH solution, stir evenly to make the pH value reach 9-11, open the water inlet valve 29 and add 1500Kg water, stir for 10 minutes to clarify;

[0066] C, acid addition reaction: After 20-24 hours of precipitation, absorb the supernatant liquid with the liquid suction device 8, then start the stirring device 7, and open the acid liquid valve 27 during stirring to process industrial hydrochloric acid to make the pH value reach 5-7;

[0067] D. Water washing: Then open the water inlet valve 29 and add 2500Kg of water, stir for 10 minutes, clarify, after ...

Description

technical field [0001] The invention belongs to the technical field of producing metatitanic acid from titanium white pulp, and in particular relates to a production method and equipment for producing metatitanic acid from titanium white pulp. Background technique [0002] When turpentine is used as the main raw material to process and produce borneol, β-pinene, α-pinene and rough brain, etc., metatitanic acid is used as a catalyst to cause isomerization of α-pinene. The general synthesis method of metatitanic acid is the reaction of sulfuric acid ilmenite and sulfuric acid to generate titanyl sulfate, after purification, freezing to remove ferrous sulfate, pressure filtration and concentration, then hydrolyze titanyl sulfate, then wash with water, filter and dry , to obtain metatitanic acid. The process is: FeTiO 3 +3H 2 SO 4 →FeSO 4 +Ti(SO 4 ) 2 +3H 2 OFeTiO 3 +2H 2 SO 4 →FeSO 4 +TiOSO 4 +2H 2 OTi(SO 4 ) 2 +H 2 O→TioSO 4 +H 2 SO 4 TiOSO 4 +2H 2 O→H 2...
