Problems solved by technology
Using the existing single furnace body, not only cannot guarantee the average chlorination rate of titanium carbide reaches 85%, but also cannot meet the production process requirements, and the economy is not high
At the same time, due to the expansion of production capacity, if the diameter of the furnace body is simply increased, the feeding method at the bottom of the furnace body does not meet the process requirements, and the reaction temperature in the furnace is more difficult to control

The invention discloses a secondary reaction furnace for preparing titanium tetrachloride by low-temperature chlorination, and belongs to the technical field of design and manufacture of metallurgical production equipment. The invention provides a secondary reaction furnace for preparing titanium tetrachloride by low-temperature chlorination, which is easy to control the reaction temperature and can effectively increase the chlorination rate. The secondary reaction furnace includes a fluidized bed, a slurry return interface and a reaction furnace body, at least two reaction cylinders are arranged at the middle and lower part of the reaction furnace body, and each reaction cylinder is opened at the bottom. A set of the fluidized bed is arranged, and the return mud transfer interface is arranged in the middle and upper part of the reaction furnace body; during the low-temperature chlorination reaction, chlorine gas is input from the bottom through the fluidized bed into the reaction furnace In the furnace body, the normal-temperature slurry that regulates the internal reaction temperature of the reaction furnace body is input into the reaction furnace body from the middle and upper part of the reaction furnace body with the cooperation of the external slurry return system through the slurry return interface.
Description
technical field [0001] The invention relates to a secondary reaction furnace, in particular to a secondary reaction furnace for preparing titanium tetrachloride by low-temperature chlorination, and belongs to the technical field of design and manufacture of metallurgical production equipment. Background technique [0002] my country's vanadium-titanium magnetite resources are very rich, and the comprehensive utilization value is extremely high. The process of producing titanium tetrachloride by selective chlorination at low temperature is the first domestic titanium extraction technology of a steel group company, and its production line and production equipment currently only exist in the steel group company. The high-temperature carbonization-low-temperature selective chlorination process route is economical and mature, and has been used as the main production process in the domestic titanium extraction industry. As the core equipment of the chlorination system, the low-te...
