Abstract
the invention discloses a titanic chloride atomized method of magnesium method to produce sponge Ti, which is characterized by the following: assembling one cyclone atomized sprayer (2) in the outlet of titanic chloride inlet (1) of reactor (3); controlling the sprayer (2) as column shape; setting cyclone blade (7) in the sprayer; atomizing at high-speed in the sprayer (2); forming micro-fog drip with solid or hollow cone; leaving the sprayer (2) at high-speed; spraying on the metal magnesium; reducing.
Description
Technical field
The present invention relates to titanium sponge production, produce the titanium sponge method in particular to the magnesium method.
Background technology
Produce in the process of titanium sponge in the magnesium method, need to make titanium tetrachloride by titanium mineral earlier, it is used magnesium metal reduction, make titanium sponge after the purification.Normally the titanium tetrachloride under the normal temperature is directly added in the reactor and the MAGNESIUM METAL contact reacts by pipeline.Under the bigger situation of reactor capacity, reactor temperature is up to 800～920 ℃, and titanium tetrachloride enters to the reactor middle part, and most of titanium tetrachloride can gasify and react rapidly with melt metal magnesium, restores titanium; To add speed fast but because of titanium tetrachloride, the titanium tetrachloride of some liquid phase fails to gasify, MAGNESIUM METAL generation vigorous reaction with regard to direct and reactor center position, cause in this position reduction heat quantity set, this position titanium sponge Yin Gaowen and sintering brings following consequence: (1) reduction finishes, distills when purifying, agglomerating titanium sponge compact structure, impurity such as remaining MAGNESIUM METAL and magnesium chloride are difficult to remove, and influence quality product; (2) agglomerating titanium sponge compact structure is difficult to be crushed to the granularity that product index is stipulated; (3) user uses this titanium sponge to add man-hour at vacuum arc fumace titanium ingot, is difficult to make electrode, even made electrode, and easy fracture, short circuit when melting and burn out crucible, even the accident of blasting.Up to now, also do not solve the method appearance of this difficult problem.
Summary of the invention
Purpose of the present invention just is to provide a kind of magnesium method to produce the titanium tetrachloride atomising method of titanium sponge, the agglomerating difficult problem to solve reactor center position titanium sponge Yin Gaowen in the prior art.
For solving this difficult problem, the physicochemical property that the contriver produces the structure of reactor characteristics of titanium sponge and material to the magnesium method are studied and are thought deeply, through overtesting, invented method with the titanium tetrachloride atomizing, reduction reaction is carried out in reactor comparatively equably.Therefore solution of the present invention is that shower nozzle is a cylindrical shape at whirlwind-type atomizer of exit installation of the titanium tetrachloride inlet pipe of reactor, and inside is equipped with swirl vane, and outlet is designed to taper shape, to improve gas velocity.The liquid phase titanium tetrachloride that enters from header tank is through the swirl vane of shower nozzle, just the liquid of formation high speed rotating flows and atomizes in shower nozzle, mist droplet is solid circular cone or hollow cone or other shape, after throwing away at a high speed, the flaring exit of device forms mist droplet again, be ejected on the MAGNESIUM METAL, carry out reduction reaction.
Above-mentioned shower nozzle diameter is 20～100mm, and length is 30～200mm, and the outlet hole diameter is 4～10mm.
Magnesium method of the present invention is produced the titanium tetrachloride atomising method of titanium sponge, overcome liquid titanium tetrachloride in the prior art at reactor center position and MAGNESIUM METAL vigorous reaction, influence the difficult problem of titanium sponge quality, after the titanium tetrachloride atomizing, reduction reaction in the reactor is carried out equably, avoid the heat accumulation problem of original technology, thereby guaranteed the quality product of titanium sponge.The present invention is applicable to the producer that adopts the magnesium method to produce titanium sponge.

Embodiment
Following examples can clearer explanation the present invention.
Embodiment
In certain titanium sponge factory, adopt the magnesium method to produce titanium sponge.Reactor 3 is that a periphery is equipped with the container that pipe is established in heating, and MAGNESIUM METAL wherein is molten state.As shown in Figure 1, in the exit of the titanium tetrachloride inlet pipe 1 of reactor 3 a whirlwind-type atomizer 2 is installed.Shower nozzle 2 is a cylindrical shape, and its length is 150mm, and diameter is 60mm; Shower nozzle 2 wall thickness 3mm, inside is equipped with swirl vane 7, exports to be taper shape, and the outlet hole diameter is 8mm.The liquid phase titanium tetrachloride that enters from header tank is through the swirl vane 7 of shower nozzle, just the liquid of formation high speed rotating flows and atomizes in shower nozzle 2, mist droplet is solid circular cone or hollow cone, after throwing away at a high speed, the flaring exit of device forms mist droplet again, be ejected on the MAGNESIUM METAL, carry out reduction reaction, produce titanium sponge and magnesium chloride product.
Magnesium chloride product is discharged from, and titanium sponge is then sent to and distilled purification, removes impurity, and is broken again, obtains the titanium sponge product.
Claims (2)
1. a magnesium method is produced the titanium tetrachloride atomising method of titanium sponge, it is characterized in that an exit installation whirlwind-type atomizer (2) at the titanium tetrachloride inlet pipe (1) of reactor (3), shower nozzle (2) is a cylindrical shape, and inside is equipped with swirl vane (7), exports to be taper shape; The liquid phase titanium tetrachloride that enters from header tank is through the swirl vane (7) of shower nozzle, the liquid of formation high speed rotating flows and atomizes in shower nozzle (2), mist droplet is solid circular cone or hollow cone, after throwing away at a high speed, the flaring exit of shower nozzle (2) forms mist droplet again, be ejected on the MAGNESIUM METAL, carry out reduction reaction.
2. produce the titanium tetrachloride atomising method of titanium sponge according to the described magnesium method of claim 1, it is characterized in that described shower nozzle diameter is 20～100mm, length is 30～200mm, and the outlet hole diameter is 4～10mm.。
