Below, the recovery system containing vanadium mud produced except vanadium in conjunction with above-mentioned crude titanic chloride is described in detail according to an exemplary embodiment of the present invention recovery process.
What this technique produced except vanadium process with aluminium powder contains vanadium mud for raw material, and chlorine is oxygenant, and the mixture of NaCl and KCl is heating medium (fused salt), and molten salt furnace 1 is separated and VOCl as titanium tetrachloride 2the equipment of oxidation, condenser 7 is as VOCl 3recovery system.Wherein, by weight percentage, containing TiCl in vanadium mud 4content is 80 ~ 85%, TiCl 3content is 8 ~ 10%, VOCl 2content is 1 ~ 3% and AlCl 3content is 3 ~ 7%, but the present invention is not limited thereto, method of the present invention can also process other except crude titanic chloride except vanadium process produce comprise titanium tetrachloride liquid and VOCl 2solid containing vanadium mud.The mass ratio of NaCl and KCl in addition in heating medium controls to be 4: 6 ~ 2: 8.This technique specifically comprises the following steps:
(1) mixed by predetermined proportion by heating medium (NaCl and KCl) and be preheated to molten state, now temperature is 600 ~ 750 DEG C, then adds in molten salt furnace 1, and utilizes Graphite Electrodes 3 and 4 to heat to remain within the scope of 600 ~ 750 DEG C.
(2) will add in molten salt furnace containing vanadium mud, and be insulation 20 ~ 30min under the condition of 600 ~ 750 DEG C in temperature, to evaporate and to collect the titanium tetrachloride contained in vanadium mud, reach the object of separating titanium.
(3) ratio being 40: 1 ~ 50: 1 according to the mass ratio containing vanadium mud and chlorine passes into chlorine, and control chlorine pass into speed, lead to chlorine in 20 ~ 30min, the chlorine passed into and the VOCl contained in vanadium mud 2solid reacts the VOCl generating gaseous state under the temperature condition of 600 ~ 750 DEG C 3.
(4) condensation is reclaimed the VOCl that molten salt furnace 1 is discharged 3gas passes in condenser 7, keeps the temperature in condenser to be-5 ~ 10 DEG C, obtains highly purified VOCl 3liquid and chlorine, realize VOCl 3and Cl 2separation, wherein, highly purified VOCl 3liquid sends into VOCl 3preserve in product stock unit 8, excessive chlorine can pass into alkali pond.
In above-mentioned steps (1) in (3), the temperature controlled in molten salt furnace is 600 ~ 750 DEG C can make fused salt keep flowing, wherein, steams TiCl in step (2) 4time, be dispersed in the fused salt of molten state containing vanadium mud, heating surface area is large and even, be beneficial to raising and steam efficiency, if do not adopt molten salt furnace and the temperature controlled in molten salt furnace in said temperature scope, due to lower containing solid load ratio in vanadium mud, and liquid content is more and fusing point is close, after steaming liquid phase, remaining solid matter easily hardens, and causes further vanadium separating-purifying difficulty; And in the chlorination process of step (3), dichloro vanadyl is dispersed in the fused salt of molten state, there are more chance and chlorine reaction, and speed of reaction is fast under above-mentioned hot conditions, if when temperature is lower than 600 DEG C, fused salt mobility is bad, if when temperature is higher than 750 DEG C, dichloro vanadyl may steam, and it is too high to consume energy.
Preferably, in above-mentioned steps (1) in (3), the temperature controlled in molten salt furnace is 650 ~ 700 DEG C.
Further, in described step (2) and step (3), in molten salt furnace, pass into rare gas element (such as nitrogen), keep fused salt 2 and the flowing containing vanadium mud, to mix.
First this technique evaporate removing containing the TiCl in vanadium mud 4, then utilize VOCl 2and VOCl 3different physical propertiess and chemical property, use oxygenant Cl 2vOCl in oxidation molten salt furnace 2s () generates VOCl 3(g), VOCl 3g () cools in a cooling system and forms liquid, thus be separated the object reaching and extract V, that is, makes VOCl by chlorine 2transformed to lower boiling by high boiling point, thus reach the effect of purification.
In order to understand above-mentioned exemplary embodiment of the present invention better, below in conjunction with concrete example, it is further described.
This example adopts the molten salt furnace process TiCl of 300 tons/year 4what aluminium powder produced except vanadium treating process contains vanadium mud.Wherein, the diameter of molten salt furnace is 800mm, and power is 60kW, and type of heating is Graphite Electrodes heating, often a collection of can process 300Kg containing vanadium mud, power consumption 80kWh.
Specific embodiment is: the mass ratio of (1) preparation NaCl and KCl is the fused salt 600Kg of 4: 6, and be preheated to molten state, now temperature is 650 DEG C, is then injected in the molten salt furnace that diameter is, and keeps temperature to be 650 DEG C by Graphite Electrodes heating; (2) switch tail gas to refining and distilling still, be communicated with the venting port of molten salt furnace by refining and distilling still, and in molten bath, feed nitrogen by air-supply duct, maintenance gas supply flow is 50m 3/ h, then injects 300Kg containing vanadium mud, is incubated 30min, tail gas (the i.e. TiCl obtained at 650 DEG C in molten salt furnace 4gas) escape and enter refining and distilling still from venting port; (3) switch tail gas to condenser, namely close the connection between refining and distilling still and the venting port of molten salt furnace, and be communicated with molten salt furnace venting port by condenser, the nitrogen flow in reduction vapor pipe is to 48m 3/ h, and start to molten bath, to pass into chlorine from vapor pipe, control chlorine flowrate is 12m 3it is 650 DEG C that/h controls temperature of reaction, and continue 30min, the tail gas obtained is (containing VOCl 3gas and chlorine) discharge from venting port and be sent to condenser and be condensed to room temperature, obtain liquid VOCl 3product.(4) increase nitrogen flow, close chlorine, inject next batch containing vanadium mud, continue next batch ground refining.Wherein, process five batches needs deslagging containing after vanadium mud continuously, returns to elemental height to make the fused salt liquid level in molten salt furnace.
Present invention achieves disposable recovery titanium tetrachloride and refine valuable element titanium in mud and vanadium, wherein, Ti yield>=95%, V yield>=85%, VOCl 3product purity>=98wt%, namely yield is high, and the product purity obtained is high, especially can obtain highly purified VOCl 3, can be used for production high-quality high purity vanadium.The present invention be conducive to resource efficiency utilization, technical process is short, production unit is simple, be easy to realize industrialization.And refining mud belongs to high pollution thing, the present invention is turned waste into wealth in realization, create profit while, solve problem of environmental pollution, there is very high economic and social benefit.
Although above by describing the present invention in conjunction with exemplary embodiment, it will be apparent to those skilled in the art that when not departing from the spirit and scope that claim limits, various amendment and change can be carried out to exemplary embodiment of the present invention.
