Embodiment
The utility model provides a kind of stir shaft of continuous acidolysis reactor.Specifically, according to the utility model, the stir shaft of described continuous acidolysis reactor comprises the first stir shaft and the second stir shaft, and is respectively arranged with many groups of the first twayblades and many groups the second twayblade that is arranged in symmetrically the axle both sides on the first stir shaft and the second stir shaft.By twayblade, sour ore deposit mixture and spent acid are stirred, increased acid, ore deposit contact area, reduced the poor phenomenon of local reaction caused because mixing inequality; Can prevent the ilmenite concentrate conglomeration, so that form meal, solute effect is good; Can significantly improve acidolysis rate.According to the stir shaft of continuous acidolysis reactor of the present utility model, obviously improved the whole yield of acidolysis, reduced the ilmenite concentrate loss.
Describe below with reference to accompanying drawings the stir shaft according to continuous acidolysis reactor of the present utility model in detail.
Fig. 1 shows the main TV structure figure according to the stir shaft of the continuous acidolysis reactor of exemplary embodiment of the present utility model.Fig. 2 shows the sectional structure chart along the intercepting of A-A line of the stir shaft of the continuous acidolysis reactor in Fig. 1.
See figures.1.and.2, according to the stir shaft of continuous acidolysis reactor of the present utility model, comprise the first stir shaft 1 and the second stir shaft 1', and be respectively arranged with many group the first twayblades 2 and many groups the second twayblade 2' on the first stir shaft 1 and the second stir shaft 1'.At length say, in the continuous acidolysis reactor, according to material, operation is divided into four zones: reaction induced district II, main reaction region III, reaction maturation zone (not shown) and disintegrating area I.In reaction induced district II, main reaction region III and disintegrating area I, unlike the prior art, be respectively arranged with many group the first twayblades 2 and many groups the second twayblade 2' on the first stir shaft 1 and the second stir shaft 1'.Working medium in the continuous acidolysis reactor mainly comprises solid phase (titanyl sulfate), liquid phase (98% vitriol oil and 20% spent acid), gas phase (SO
2, SO
3and H
2s) etc., the scope of working temperature is at 165 ℃～220 ℃.
According to the utility model, the first stir shaft 1 is parallel and adjacent with the second stir shaft 1', and the first twayblade 2 distributes along the length direction of the first stir shaft 1, and the second twayblade 2' distributes along the length direction of the second stir shaft 1'.In addition, be positioned at the first twayblade 2 on the first stir shaft 1 and be positioned at the second twayblade 2' on the second stir shaft 1' respectively along the length direction of stir shaft separately decussate in twos.After acid ore deposit mixture enters the continuous acidolysis reactor, by the first twayblade 2 and the second twayblade 2', that sour ore deposit mixture composite stirring is even, increase acid, ore deposit contact area, can efficient absorption diluting concentrated sulfuric acid heat energy, thereby induced reaction, prevent the ilmenite concentrate conglomeration, so that formation meal, reaction efficiency is high, speed of response is fast, interval reaction makes the main reaction phase temperature reach 220 ℃ of left and right, and the heat energy discharged can keep the temperature in the continuous acidolysis reactor relatively constant, and the reaction stage of maturity makes reaction more thorough.Reaction is accompanied by moisture and generates, the solid formation produced easily lumps, the first twayblade 2 in the disintegrating area I and the second twayblade 2' are because leaves density doubles than single blade, the effect of the first twayblade 2 and the second twayblade 2' and storeroom is doubled, can by variable grain shape solid formation, decompose levigate by interlobate friction, extruding and shearing, stop caking, improve the titanyl sulfate (TiOSO generated with respect to single blade stirring action in material usefulness
4) solid is Powdered, humidity is moderate, and yellow and bright color generates solid formation loose, and continuous acidolysis rate, dissolved efficiency significantly improve, and the whole yield of acidolysis improves obviously (more than 1.5%), and the intermediates quality is more stable.
