Description
Technical field
The utility model belongs to titanium sponge production field, and the high temperature in more particularly to inverted U reduction-retort distillation stage is dredged
Exchange device.
Background technology
Magnesium-reduced titanium tetrachloride method production titanium sponge is broadly divided into reduction and two stages of distillation, inverted U reduction-retort
Terminate to enter the distillation stage in reduction, start to need to be docked cold end reactor and hot junction reactor before distilling, during docking
The vertical tube needed in the big lid in hot junction loads onto high-temperature valve, and the vertical tube of the big lid of cold end loads onto seal plug.Distillation stage total duration about 100
Hour, the magnesium of hot junction inside reactor is remained in the distillation stage and magnesium chloride passes sequentially through the big Gai Heng in hot junction in the form of a vapor
Vertical tube and the vertical and horizontal pipe of the big lid of cold end, entering cold end reaction internal condensation turns into solid-state.Because cold junction temperature is relatively low, in magnesium vapor
The condensation of the exit below cold end vertical tube is easy to during entering cold end with chlorination magnesium vapor and forms condensate.With
The increase of duration is distilled, this position condensate can be cumulative, if taken no action to, ultimately results in the blocking of cold end vertical tube,
So as to it be interrupted to causing to distill.Still can not effectively it judge for distilling plugging degree situation in industry at this stage.
The common practice of current domestic titanium sponge industry is periodically to divide the plug for opening cold end vertical tube several times in the distillation stage
Plugging situation is checked, once find that plugging clears up condensate manually by operator using drill rod.Needed before opening plug every time
Suspend distillation, argon gas protection is filled with simultaneously to cold end and hot junction.Need to continue ceaselessly argon filling in the condensate of cleaning, with
It is useless to ensure that the Sponge Titanium in the reactor of hot junction is not arrived by air pollution.Cleaning vacuumizes to cold end hot junction again after terminating
Continue to distill.Suspend distillation every time, open and check cleaning, then the process for recovering to distill needs to take nearly 3 hours, this time
Interior power consumption, argon gas consumption are to influence a key factor of cost of sponge Titanium.
