Fluidized chlorination furnace

Abstract

The invention relates to the field of fluidized chlorination furnaces and discloses a fluidized chlorination furnace. The fluidized chlorination furnace includes a furnace body (1) having an inner chamber, a material feeding inlet, an air inlet, an air outlet and a slag discharge outlet. The inner chamber is respectively connected to the material feeding inlet, the air inlet, the air outlet and the slag discharge outlet. The furnace body (1) includes a reaction part furnace body (2), of which at least one part of the furnace wall is transparent. When a thermal-state test is carried out by the fluidized chlorination furnace, researches can observe reaction situation inside the fluidized chlorination furnace through the transparent part of the furnace wall during the thermal-state test, thereby researching chlorination characters and fluidization state of materials in the fluidized chlorination furnace.

Description

technical field [0001] The invention relates to the field of fluidized chlorination furnaces, in particular to a fluidized chlorination furnace. Background technique [0002] The production of titanium tetrachloride by boiling chlorination is one of the important processes in the production of titanium dioxide and sponge titanium by the chlorination method. This process generally uses titanium-containing raw materials and chlorine gas for chlorination in a boiling chlorination furnace to obtain an important intermediate in the titanium industry. The product is titanium tetrachloride. [0003] At present, relevant research institutions generally use fluidized chlorination furnaces to conduct cold-state tests to study the chlorination characteristics and fluidization state of materials in fluidized chlorination furnaces. However, since the reaction of the fluidized chlorination furnace in actual production is in a hot state, the composition of the material in the furnace is c...

AI Technical Summary

Problems solved by technology

However, since the reaction of the fluidized chlorination furnace in actual production is in a hot state, the composition of the material in the furnace is constantly changing, and the temperature, airflow distribution, and characteristics of the material itself are different from the cold test, so it is difficult to pass the cold test. Method to infer the actual operation of the chlorination furnace

The existing fluidized chlorination furnace usually includes a furnace body with an internal cavity, a feed port, an air inlet, a gas outlet, and a slag discharge port, and the internal cavity is connected to the feed port, the air intake port, the gas outlet, and the slag discharge port respectively. , the furnace body includes a reaction section furnace body made of opaque refractory materials, so researchers cannot observe the reaction inside the boiling chlorination furnace in the thermal test through the existing reaction section furnace body in order to study boiling chlorination Chlorination characteristics and fluidization state of the material in the furnace
