The invention relates to a process and a special device for refining and removing
alum continuously for TiCL4, which solves the problems that the TiCL4 has production cost, needs frequent washing, replacement and supplementation of
copper wires, can not implement
continuous operation, has high labor intensity and cause environmental
pollution. The process is as follows:
mineral oil and rough TiCL4 is added into a circulating
system according to a proportion of between 1.2 to 1000 and 1.6 to 1000, and VOCL3 in the
mineral oil and the TiCL4 contacts adequately and react to generate a high boil point matter; materials are forced to be circulated and heated by a
circulating pump, and the
heating temperature is between 137 and 145 DEG C; the
mineral oil and the TiCL4 are continuously added into the circulating
system according to the output requirement, so as to realize the
continuous production; a semi-finished product of the TiCL4 is obtained after
distillation, and the high boil point matter and other high boil point impurities in the
distillation are removed. The special device for finely producing and removing
alum continuously for the TiCL4 consists of a rough tatinium overhead tank, the
circulating pump, a
heat exchanger, a mixer, a
distillation kettle, an
alum slurry tank, a packing
tower, a condenser, a semi-finished tank, a mineral oil grove and a
metering pump.
