Abstract
The utility model discloses a titanium tetrachloride recycling device which comprises a steeling tank. The titanium tetrachloride recycling device is characterized by also comprising a paddle dryer, a vanadium slag tank, a condenser and a recycling tank, wherein the settling tank is connected into an inlet of the paddle dryer through a pipeline; the vanadium slag tank is connected with a slag outlet of the paddle dryer; a gas outlet of the paddle dryer is connected with an inlet of the condenser through a pipeline; a liquid outlet of the condenser is connected on the recycling tank through a pipeline; a steam pipeline is connected at a gas inlet of the paddle dryer; and a steam adjusting valve is arranged on the steam pipeline. As the paddle dryer is adopted for treating titanium tetrachloride slurry, the utilization rate of heat sources can be high, the loss of titanium tetrachloride caused by improper hydrolysis control due to adopting hydrolysis technique is avoided, and simultaneously the problem that the titanium tetrachloride slurry is dismatched with a chlorination furnace in heat quantity due to being large in quantity when part of the slurry is returned to a chlorination furnace system is solved.
Description
Technical field
The utility model relates to a kind of device that reclaims titanium tetrachloride, relates in particular to a kind of device that adopts paddle-dryer from titanium tetrachloride mud reclamation titanium tetrachloride.
Background technology
Titanium tetrachloride is a kind of important intermediates of producing titanium sponge and titanium white.There are many detrimental impurity in the crude titanic chloride of fluidizing chlorination production, by distillation, rectificating method can remove the high lower-boiling impurity in the crude titanic chloride, remove vanadium by the chemical method aluminium powder and remove foreign matter of vanadium in the titanium tetrachloride.
In above-mentioned refining production process, can produce a large amount of titanium tetrachloride mud, wherein only aluminium powder removes and produces the titanium tetrachloride mud that contains solid impurities such as VOCl2 in the vanadium production, mud amount accounts for 1/10 of titanium tetrachloride product volume, because titanium tetrachloride mud generation is big, if do not reclaimed, can cause a large amount of losses of titanium tetrachloride.
At present, removing one of the vanadium titanium tetrachloride treatment of mud method that contains that vanadium produces for aluminium powder is to adopt method for hydrolysis earlier, utilizes afterwards to contain vanadium mud, last discard processing after the milk of lime neutralizing hydrolysis.This method process control procedure is loaded down with trivial details, and equipment requirements is higher, and is not high to the recycling of titanium tetrachloride.
Domestic denomination of invention is that " titanium tetrachloride contains vanadium treatment of mud technology and equipment ", publication number disclose the FeCl that contains that produces in the refining production process of processing titanium tetrachloride for the patent of invention of " CN1415547 "
3The method of titanium tetrachloride mud, but its directly refining system is produced contain FeCl
3Titanium tetrachloride mud be back in the chlorination system chlorination furnace since produce in the treating process contain FeCl
3Mud amount is few, and chlorination system can absorb processing, but that aluminium powder removes the vanadium slag mud amount that vanadium produces is bigger, if directly return, exists the amount of returning and the chlorination furnace system phenomenon that do not match.
The utility model content
In view of this, the purpose of this utility model provides a kind of device that reclaims titanium tetrachloride, solved the problem that adopts hydrolysis process to cause the titanium tetrachloride loss, solved refining aluminium powder simultaneously and be back to chlorination system and the unmatched problem of chlorination furnace system thermal except that the vanadium titanium tetrachloride mud that contains that vanadium produces.
Above-mentioned purpose realizes by following proposal:
A kind of device that reclaims titanium tetrachloride, it comprises subsider, it is characterized in that, this device also comprises paddle-dryer, vanadium slag jar, condenser and accumulator tank, wherein said subsider inserts the import of described paddle-dryer by pipeline, and described vanadium slag jar is connected on the slag notch of described paddle-dryer; Import by the pipe connection condenser on the air outlet of described paddle-dryer, the liquid outlet of described condenser by pipe connection on accumulator tank; And on an inlet mouth of described paddle-dryer, be connected with steam-pipe, on described steam-pipe, steam regulating valve be installed.
Device according to above-mentioned is characterized in that, is connected with the argon gas pipeline on another inlet mouth of described paddle-dryer, on described argon gas pipeline the argon gas variable valve is installed.
Device according to above-mentioned is characterized in that, is connected the inlet mouth of drop catcher on the air outlet of described condenser, and the liquid outlet of described drop catcher is connected on the accumulator tank.
Device according to above-mentioned is characterized in that, the outlet of described accumulator tank by pipe connection to transferpump.
Device of the present utility model has following beneficial effect: adopt paddle-dryer to handle titanium tetrachloride mud, thermal source utilization ratio height has been avoided the titanium tetrachloride loss of adopting hydrolysis process to cause owing to hydrolysis control is improper; Solved simultaneously part titanium tetrachloride mud be back to the chlorination furnace system because the mud amount of returning is big in the chlorination furnace heat phenomenon that do not match; Can realize the production serialization, processing unit is simple, operational safety, titanium tetrachloride rate of recovery height.
Description of drawings
Fig. 1 is the structural representation that the utility model reclaims the device of titanium tetrachloride.
Embodiment
Referring to Fig. 1, the device of recovery titanium tetrachloride of the present utility model comprises subsider 1, paddle-dryer 2, vanadium slag jar 5, condenser 3 and accumulator tank 4, wherein subsider 1 is by the import of pipeline access paddle-dryer 2, and vanadium slag jar 5 is connected on the slag notch of paddle-dryer 2; Import by pipe connection condenser 3 on the air outlet of paddle-dryer 2, the liquid outlet of condenser 3 by pipe connection on accumulator tank 4; And on an inlet mouth of paddle-dryer, be connected with steam-pipe, steam regulating valve 9 is installed on steam-pipe, on another inlet mouth of paddle-dryer 2, be connected with the argon gas pipeline, argon gas variable valve 8 is installed on the argon gas pipeline.
Be connected the inlet mouth of drop catcher 6 on the air outlet of condenser 3, the liquid outlet of drop catcher 6 is connected on the accumulator tank.The outlet of accumulator tank 4 by pipe connection to transferpump 7.
Use the process of this device recovery titanium tetrachloride as follows:
Aluminium powder removes the vanadium titanium tetrachloride mud that contains that the vanadium system produces and is collected in the subsider 1, after natural subsidence, the titanium tetrachloride clear liquid with contain the layering of solid mud underflow.
Subsider 1 bottom produces and contains solid mud from flowing in the paddle-dryer 2; Paddle-dryer 2 is selected the steam source of 0.6MPa for use, and titanium tetrachloride mud is heated; Titanium tetrachloride liquid in the mud is gasified, and overflows from paddle-dryer 2 tops, enters in the condenser 3; The dry slagging of solid impurity in the while mud.
Feeding argon gas in the paddle-dryer 2 in the production process, argon gas guarantee that by control automatically the vapor pressure of drying machine interior 2 is steadily controlled.
Paddle-dryer 2 selects for use the steam of 0.6MPa as heating source, automatic regulative mode is adopted in temperature control, guarantees temperature-stable in the mud drying process, simultaneously the special tectonic of paddle-dryer 2 blades, guarantee that material does not have the dead angle, the material finish-drying in the paddle-dryer 2.
Titanium tetrachloride vapors after paddle-dryer 2 gasifications enters into and flow to titanium tetrachloride accumulator tank 4 after condenser 3 is condensed into liquid state, and uncooled titanium tetrachloride gases continues to reclaim by mist eliminator.
