Problems solved by technology
Since the chlorination reaction is an exothermic reaction, as the furnace size increases, the heat generated by the reaction in the furnace increases. The furnace design adopts an insulation structure, and the heat energy accumulated in the furnace cannot be well dissipated to the outside of the furnace. The corrosion of equipment is accelerated under the action of medium and high temperature
Since the inner lining is mostly built with shaped refractory materials, there are many horizontal, vertical and radial brick joints in the construction. In addition, if the brick joints are not tight during the construction, chlorine gas can easily penetrate into the building through the brick joints. The outer wall, causing corrosion and perforation to the steel plate

Embodiment Construction
[0022] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.
[0023] figure 2 is a schematic longitudinal sectional view of a fluidized chlorination furnace 200 according to an exemplary embodiment of the present invention. refer to figure 2 , The boiling chlorination furnace 200 includes a boiling section 210 , an expanding section 220 , a straight section 230 and a furnace cover 240 . The boiling section 210 is arranged below the boiling chlorination furnace 200, and the titanium ore and chlorine gas are fully mixed in the boiling section 210 and the chlorination reaction of the titanium ore begins. The expansion section 220 is arranged above the boiling section 210, and the expansion section 220 can provide the space required for the chemical reaction to occur. The straight section 230 is arranged above the enlarged section 220, and the reacted material can pass through the straight section 230 and be disch...

Description
technical field [0001] The invention relates to a fluidized chlorination furnace and a manufacturing method thereof, in particular to a fluidized chlorination furnace with a long maintenance period and a manufacturing method thereof. Background technique [0002] The production of sponge titanium is the basic link of the titanium industry, because sponge titanium is the raw material for titanium materials, titanium powder and other titanium components. Usually, the production process of sponge titanium mainly includes: turning ilmenite into titanium tetrachloride, then putting it into a sealed stainless steel tank, filling it with argon gas, and making them react with metal magnesium. Among them, titanium tetrachloride is mainly used to produce titanium sponge, titanium dioxide and titanium trichloride. There are many ways to prepare titanium tetrachloride, mainly including boiling chlorination, molten salt chlorination and shaft furnace chlorination. Boiling chlorination ...
