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 metallurgicalproduction equipment. The invention provides the secondary reaction furnace for preparing the titanium tetrachloride by the low-temperature chlorination, which easily controls the reaction temperatureand can effectively improve the chlorination rate. The secondary reaction furnace comprises fluidized beds, a mud returning conveying interface and a reaction furnace body; at least two reaction cylinder bodies are arranged in the lower middle part of the reaction furnace body; one set of fluidized bed is arranged at the open bottom of each reaction cylinder body; the mud returning conveying interface is formed in the upper middle part of the reaction furnace body; in the low-temperature chlorination reaction process, chlorine is inputted into the reaction furnace body from the bottom of thefluidized bed; normal temperature mud for regulating and controlling reaction temperature inside the reaction furnace body is inputted into the reaction furnace body from the upper middle part of thereaction furnace body through the mud returning conveying interface under the matching of an external mud returning system.
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...
