8. it is a kind of using the residual neat recovering system of any of claims 1-7 to titanium sponge liquid produced during the preparation process
The method of state magnesium chloride progress waste heat recycling, which is characterized in that including：
S1, the collector (2) receive the liquid magnesium chloride of reacting furnace (A) discharge；
Liquid magnesium chloride is discharged to the flow controller (6) in S2, the collector (2), and the flow controller (6) receives institute
It states the liquid magnesium chloride of collector (2) discharge and is injected into the revolving cup (10), wherein gone out by the flow controller
Material mouth control valve (7) controls the aperture of the flow controller discharge port to control liquid magnesium chloride into the revolving cup (10)
Speed；
S3, flown out institute due to the effect of centrifugal force by the liquid magnesium chloride in the revolving cup (10) of the driver (11) driving rotation
It states revolving cup (10) and is moved towards the inner wall of the cooling chamber, the liquid magnesium chloride becomes spherical, magnesium chloride in the process
Grain；
S4, the magnesium chloride spheric granules encounter move downward after the inner wall of the cooling chamber with from the cold wind import (17) into
Enter the cold air heat exchange of the cooling chamber, the cooling is discharged from the cooling chamber discharge port in magnesium chloride spheric granules after cooling
Device (13), hot-air escape and enter the waste heat boiler (22) from the hot-blast outlet and exchange heat.
