Abstract
The invention relates to a titanium tetrachloride refining processing technology. The technology includes: bringing the coarse titanium tetrachloride coming from a chlorination workshop into an elevated tank, passing the coarse titanium tetrachloride through a flowmeter and adding it into a tower from the middle part of a float valve tower, performing air flow exchange when the coarse titanium tetrachloride and a backflow fluid encounter the rising steam in a distillation kettle, condensing low fluorine silicon tetrachloride and other chlorides and bringing them into a backflow tank, returning part of the chlorides to the tower top to undergo backflow, and letting the redundant overflow to a silicon tetrachloride storage pot, vaporizing low boiling point impurity removed titanium tetrachloride, and bringing it into a copper wire distillation kettle from the bottom of the float valve tower to contact the copper wire so as to remove vanadium oxytrichloride and copper, then bringing the titanium tetrachloride into a condenser and carrying out condensing, thus obtaining a refined titanium tetrachloride fluid, checking it whether it is up to the standards, then sending it to a storage pot if it is qualified, and supplying it to a reduction process, returning the high boiling point titanium tetrachloride gathered in the distillation kettle and elevated tank to a chlorination workshop thickener regularly, and discharging the tail gas of all towers and equipment into the atmosphere by an acid sealing pot. The technology provided in the invention not only is simple, but also guarantees the quality of refined titanium tetrachloride.
Description
Technical field
The invention belongs to chemical field, particularly the refining complete processing of a kind of titanium tetrachloride.
?
Background technology
Titanium sponge production is the basic link of titanium industry, and it is the raw material of titanium material, titanium valve and other titanium components.Ilmenite is become titanium tetrachloride, be put into again in the stainless cylinder of steel of sealing, fill with argon gas, they and MAGNESIUM METAL are reacted, just obtain " titanium sponge ".But the process that ilmenite is become titanium tetrachloride is a very unmanageable link.Its method mainly contains fluidizing chlorination, fused salt chlorimation and 3 kinds of methods of shaft chlorination.Fluidizing chlorination is the main method of existing production titanium tetrachloride, secondly be fused salt chlorimation, and shaft chlorination is eliminated.Fluidizing chlorination generally is that fused salt chlorimation then can be used the raw material that contains high contents of calcium and magnesium take the rich titanium material of the low higher-grade of calcium-magnesium content as raw material.No matter which kind of method is produced titanium tetrachloride, its complete processing all is difficult to dispose.
Summary of the invention
The invention provides a kind of production and processing technology of new refining titanic chloride, this production technique can be carried out effective joint disposal to the waste that produces in the production process.
A kind of titanium tetrachloride is made with extra care complete processing, enter header tank from chlorination workshop crude titanic chloride out, add in the tower through the middle part of under meter by valve tray column, when the steam that rises together with phegma and still kettle meets, carry out the air-flow exchange, the muriates such as low fluorine point silicon tetrachloride enter backflash by the overhead condenser condensation, wherein a part is returned cat head and is refluxed, the unnecessary silicon tetrachloride storage tank that overflows to, the titanium tetrachloride of having removed lower-boiling impurity is vaporized by the valve tray column bottom and enters the copper wire still kettle, contacts with copper wire except vanadium oxytrichloride, behind the copper removal, enter condenser, condensation obtains refining titanic chloride liquid, is sent to storage tank through after the assay was approved.Supply with the reduction operation, each still kettle and header tank enrichment high boiling titanium tetrachloride arranged, regularly return chlorination workshop thickener, the tail gas of all towers and equipment enters atmosphere through the acid seal tank.
Adopt complete processing refining titanic chloride of the present invention, not only technique is simple, and can guarantee the quality of refining titanic chloride.
Description of drawings
Fig. 1 is process flow sheet of the present invention.
Embodiment
Titanium tetrachloride is that chemical formula is the mineral compound of TiCl4, is the important intermediate of producing metal titanium and compound thereof.Under the room temperature, titanium tetrachloride is colourless liquid, and is fuming in air, generates titanium dioxide solid and hydrochloric acid drop.Titanium tetrachloride is divided into crude titanic chloride and smart titanium tetrachloride, and smart titanium tetrachloride is through the art breading gained by crude titanic chloride.
As shown in Figure 1, the invention provides and a kind of crude titanic chloride is processed into the processing method of smart titanium tetrachloride, that is: remove high-boiling-point impurity by distillation first, remove lower-boiling impurity by rectifying again, by copper wire vanadium removal, produce smart titanium tetrachloride.
The refining titanic chloride process flow is as follows:
Enter header tank from chlorination workshop crude titanic chloride out, add in the tower through the middle part of under meter by valve tray column, when the steam that rises together with phegma and still kettle meets, carry out the air-flow exchange, the muriates such as low fluorine point silicon tetrachloride enter backflash by the overhead condenser condensation, wherein a part is returned cat head and is refluxed, the unnecessary silicon tetrachloride storage tank that overflows to, the titanium tetrachloride of having removed lower-boiling impurity is vaporized by the valve tray column bottom and enters the copper wire still kettle, contact except vanadium oxytrichloride with copper wire, behind the copper removal, enter condenser, condensation obtains refining titanic chloride liquid, is sent to storage tank through after the assay was approved.Supply with the reduction operation, each still kettle and header tank enrichment high boiling titanium tetrachloride arranged, regularly return chlorination workshop thickener, the tail gas of all towers and equipment enters atmosphere through the acid seal tank.
The titanium tetrachloride that adopts the present invention to make with extra care, technique is simple, and the titanium tetrachloride quality of producing is high, is the best raw materials for production of titanium sponge.
