Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Referring to Fig. 1, the present invention utilizes fine fraction artificial rutile to prepare the boiling chloridizing furnace of titanium tetrachloride, comprises chlorine pre-distributor 1, chlorination reaction device 2, fluidizing chlorination furnace roof 3, issuance of materials tank 4, filling tube 5, gas feed entrance 6, fluidizing chlorination outlet of still 7, returning charge entrance 8, chlorine entrance 9 and chlorine gas distributor 10.Described chlorination reaction device 2 bottoms are chlorine pre-distributor 1, and top is fluidizing chlorination furnace roof 3, between chlorination reaction device 2 and chlorine pre-distributor 1, are communicated with by chlorine gas distributor 10.Chlorine pre-distributor 1 outer wall is provided with the chlorine entrance 9 of tangential admission, and chlorination reaction device 2 outer wall lower ends are provided with returning charge entrance 8, the filling tube 5 that fluidizing chlorination furnace roof 3 is provided with fluidizing chlorination outlet of still 7 and enters from furnace roof center.Gas and unreacted completely fine powder leave boiling chloridizing furnace by fluidizing chlorination outlet of still 7, carry out subsequent disposal, by the unreacted of separating completely fine powder send back to and in chlorination reaction device 2, react again utilization by circulation returning charge entrance 8.
Described chlorine gas distributor 10 is inverted round platform tubular, and frustum cone cylinder upper end is opened wide, and lower end is provided with the stopping valve that can open or close, and the angle of round platform bus and axis is 30 ° ~ 45 °.See Fig. 2, on chlorine gas distributor 10 walls, be evenly laid with some apertures, each aperture and chlorine gas distributor outer wall are tangent, and the gas that tangentially makes of the tangential and chlorine entrance of aperture rises and enters in chlorination reaction device 2 by identical rotation direction.Make like this chlorine based on described round platform barrel with dispersion pattern spiral way, rotate in boiling chloridizing furnace reactor 2, entrainment the raw material of sending the fine powder of recycling back to and sending into from feeding tube 2 from circulation returning charge entrance 8, in strong rotation blending process, chlorination reaction occurs.Boiling chloridizing furnace inner chamber body is divided into upper and lower two regions by described chlorine gas distributor 10, and described upper area is the region with chlorination reaction, and described lower region is that the chlorine that there is no chlorination reaction distributes in advance, pre-dedusting (if having solid dust) region.
Physical strength and gas that aperture size on described chlorine gas distributor 10 and percentage of open area directly affect sparger pass through speed and the resistance of aperture.If aperture is many or diameter is excessive, can make the physical strength of sparger reduce, air-flow is little by the velocity of flow of aperture, and the kinetic energy deficiency of Stirring can not reach expected effect.Otherwise if aperture is too small or very few, chlorine is large by the resistance of sparger, the ability of consumption is just large.Suitable hole diameter and percentage of open area both can guarantee that air-flow, by the flow velocity of aperture, had enough kinetic energy, can make again the interior gas-solid of chlorination reaction device 2 form the dispersion fluidisation shape of disperse.Given this, the present invention finally determines that described hole diameter is 1～2mm, and the aperture total area is 1～3% of frustum cone cylinder chlorine gas distributor internal surface area, preferably 2%.Described aperture is arranged on the different heights of chlorine gas distributor by group, and this group aperture on sustained height is evenly offered on this highly corresponding circumference.
Described filling tube 5 tops are connected with the issuance of materials tank 4 of fine fraction artificial rutile and refinery coke mixing raw material, and junction is provided with the gas feed entrance 6 that gas is tangentially entered, and gas feed rotary cutting is to entering filling tube 5.Due to the rotation of gas feed and coordinate the tubaeform outlet diffusor of filling tube, can make to enter fine fraction mixed powder the filling tube tubaeform radial spray along chlorination reaction device 2 based on described filling tube lower end from issuance of materials tank 4 and enter in stove, carry out strong blending with the chlorine of rotation and react.
Principle of work of the present invention: chlorine is positioned at chlorine pre-distributor 1 both sides chlorine entrance 9 from boiling chloridizing furnace bottom imports, tangentially enter in chlorine pre-distributor 1, when being rotated pre-distribution, can separate the solid flying dust in chlorine, the flying dust of separating is discharged by bottom funnel-form ash port.Separate the chlorine after flying dust through chlorine pretreater 1 pre-rotation, the rotation tangential small-hole arranging on inverted round table shape chlorine gas distributor 10 again enters in chlorination reaction device 2, formation has the rotating fluid of strong shearing action, entrainment the fine fraction particulate material of sending into from filling tube 5 and circulation returning charge entrance 8, in strong rotation blending process, chlorination reaction occurs.The TiCl that reaction produces
4gas and unreacted completely fines powder etc. enter subsequent disposal system through fluidizing chlorination outlet of still 7, can send the utilization of reactor internal recycle back to from the circulation returning charge entrance 8 of chlorination reaction device lower end through the fine fraction powder of separating treatment.
The present invention has changed the flow distribution feature of the interior chlorine of existing boiling chloridizing furnace and particulate material.On the one hand, because the aperture of chlorine based on inverted round table wall rotates into chlorination reaction device with diffusion spiral way after distributing, in chlorination reaction device, form and there is the rotating fluid of strong shearing action; On the other hand, fine fraction artificial rutile and refinery coke compound from the filling tube at chlorination reaction device center with the blending of diffusion collar plate shape rotation mode rotation cl gas flow, make collision, shearing friction effect between chlorine and fine fraction artificial rutile stronger, the reaction product on artificial rutile surface is easily come off, can greatly improve chlorination reaction process.Chlorine, fine fraction artificial rutile and refinery coke carry out concentrating rotation on reactor wall surface in the mutual hybrid reaction of strong turbulent flow and caloic transmission in boiling chloridizing furnace reactor, spiral, both can avoid the adhesion on fine fraction artificial rutile and reactor wall surface, can increase again the effect that reacts to each other of chlorine and artificial rutile fine powder path, extend fine fraction artificial rutile in boiling chloridizing furnace with reaction times of chlorine, improve the efficiency of boiling chloridizing furnace.
The above embodiment of the present invention is to be only explanation example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and variations.Here cannot give exhaustive to all embodiments.Everyly belong to apparent variation or the still row in protection scope of the present invention of variation that technical scheme of the present invention amplifies out.
