Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
See 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 inlet 9 and chlorine gas distributor 10.Described chlorination reaction device 2 bottom is chlorine pre-distributor 1, and top is fluidizing chlorination furnace roof 3, is communicated with between chlorination reaction device 2 and chlorine pre-distributor 1 by chlorine gas distributor 10.Chlorine pre-distributor 1 outer wall is provided with the chlorine inlet 9 of tangential admission, and chlorination reaction device 2 outer wall lower end is 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 separated completely fine powder to be sent back in chlorination reaction device 2 by circulation returning charge entrance 8 and react utilization again.
Described chlorine gas distributor 10 is inverted round platform tubular, frustum cone cylinder open upper end, 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, chlorine gas distributor 10 wall be evenly laid with some apertures, each aperture and chlorine gas distributor outer wall tangent, the tangential and chlorine inlet of aperture tangentially make gas increase by identical rotation direction to enter in chlorination reaction device 2.Make chlorine like this based on described round platform barrel with dispersion pattern spiral way, rotate in boiling chloridizing furnace reactor 2, entrainment the fine powder of sending recycling back to from circulation returning charge entrance 8 and the raw material sent into from feeding tube 2, strong rotation in blending procedure, 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, described lower region be do not have the chlorine of chlorination reaction to distribute in advance, pre-dedusting (if having solid dust) region.
Aperture size on described chlorine gas distributor 10 and percentage of open area directly affect the physical strength of sparger and gas by the speed of aperture and resistance.If aperture is many or diameter is excessive, the physical strength of sparger can be made to reduce, air-flow is little by the velocity of flow of aperture, and the kinetic energy deficiency of Stirring then 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 ensure the flow velocity of air-flow by aperture, had enough kinetic energy, and gas-solid in chlorination reaction device 2 can be made again to 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 in this highly corresponding circumferentially evenly offering.
Described filling tube 5 top is connected with the issuance of materials tank 4 of refinery coke mixing raw material with fine fraction artificial rutile, 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 gas feed rotation and coordinate the tubaeform outlet diffusor of filling tube, can make to enter the fine fraction mixed powder filling tube from issuance of materials tank 4 enters in stove based on the tubaeform radial spray along chlorination reaction device 2 of described filling tube lower end, carries out strong blending reaction with the chlorine rotated.
Principle of work of the present invention: chlorine is positioned at chlorine pre-distributor 1 both sides chlorine inlet 9 from boiling chloridizing furnace bottom imports, tangentially enter in chlorine pre-distributor 1, can be separated the solid flying dust in chlorine while carrying out rotating pre-distribution, the flying dust separated is discharged by bottom funnel-form ash port.The chlorine after flying dust is separated through chlorine pretreater 1 pre-rotation, the rotation tangential small-hole arranged on inverted round table shape chlorine gas distributor 10 again enters in chlorination reaction device 2, form the rotating fluid with Strong shear effect, entrainment the fine fraction particulate material sent into from filling tube 5 and circulation returning charge entrance 8, in strong rotation blending procedure, chlorination reaction occurs.The TiCl that reaction produces
4gas and unreacted completely fines powder etc. enter aftertreatment systems through fluidizing chlorination outlet of still 7, and the fine fraction powder through separating treatment can be sent reactor internal recycle back to from the circulation returning charge entrance 8 of chlorination reaction device lower end and be utilized.
The present invention changes the flow distribution feature of chlorine and particulate material in existing boiling chloridizing furnace.On the one hand, due to chlorine distribute based on the aperture on inverted round table wall after rotate into chlorination reaction device to spread spiral way, formed in chlorination reaction device and there is the rotating fluid of Strong shear effect; On the other hand, fine fraction artificial rutile and refinery coke compound are rotating cl gas flow from the filling tube at chlorination reaction device center to spread the blending of collar plate shape rotation mode, make the collision between chlorine and fine fraction artificial rutile, shearing friction effect stronger, the reaction product on artificial rutile surface is easily come off, can greatly improve chlorination reaction process.In the concentrated rotation in reactor wall surface while chlorine, fine fraction artificial rutile and refinery coke carry out the mutual hybrid reaction of great turbulence level and Mass and heat transfer in boiling chloridizing furnace reactor, spiral, both the adhesion on fine fraction artificial rutile and reactor wall surface can have been avoided, can increase again chlorine and artificial rutile fine powder react to each other act on path, extend fine fraction artificial rutile in boiling chloridizing furnace with the reaction times of chlorine, improve the efficiency of boiling chloridizing furnace.
The above embodiment of the present invention is only for example of the present invention is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to technical scheme of the present invention the apparent change of amplifying out or variation be still in the row of protection scope of the present invention.
