3results about "Titanium tetrachloride" patented technology

A novel circulating fluidized bed chlorination furnace system is disclosed. The outlet of the petroleum coke feed tank is connected in parallel to the lower inlet of the chlorination furnace via a discharge pipe. The bottom of the chlorination furnace also has multiple chlorine inlets and slag discharge ports. The chlorine inlets are connected to chlorine pipes, and the slag discharge ports are connected to slag discharge pipes. The top of the chlorination furnace has an outlet, which is connected to the side inlet of a high-temperature cyclone separator via a feed pipe. The top of the high-temperature cyclone separator also has a liquid discharge port, which is connected to the top of a low-temperature cyclone separator via a liquid discharge pipe. The top of the low-temperature cyclone separator also has a liquid outlet. This invention features a compact structure, convenient installation, stable operation, and is safe and environmentally friendly. The entire reaction system is fluidized, preventing slag discharge pipe blockage. The combined use of the high-temperature and low-temperature cyclone separators ensures multiple cycles, repeated combustion, and reaction of the titanium tetrachloride mixture.

The application is suitable for the technical field of titanium chloride white, and provides a device and method for reducing slurry solid content of a low-temperature chlorination leaching system; the device comprises a chlorination furnace, a low-temperature chlorination leaching tower, a spraying part arranged at a flue gas outlet of the chlorination furnace, a spraying groove for collecting spraying water discharged from the low-temperature chlorination leaching tower, and an organic reagent injection device arranged in the low-temperature chlorination leaching tower; the spraying groove provides spraying water for a heat exchanger through a conveying pump; an output end of the heat exchanger is communicated with an input end of the spraying part through a first conveying pipeline; a solid-liquid separator is further arranged between the heat exchanger and the conveying pump, the solid-liquid separator is used for solid-liquid separation of the spraying water input by the conveying pump, and provides supernatant after solid-liquid separation for the heat exchanger; and the device further comprises a refining system, and a concentrated phase output end of the solid-liquid separator is connected in a slurry evaporation furnace of the refining system.
