Fluidized bed furnace device system suitable for high-calcium-magnesium-titanium slag chlorination

Abstract

The invention discloses a fluidized furnace device system suitable for chlorination of high-calcium magnesium-titanium slag, which comprises a fluidized furnace body, the upper part of the fluidized furnace body is a reaction chamber, the middle part is an expansion chamber, and the lower part is a boiling chamber; the boiling chamber and A high-voltage pulse assisted upper slag discharge system is set between the expansion chambers, which cooperates with the automatic slag discharger connected to the lower slag discharge port to realize effective and clean separation of impurities such as calcium and magnesium in the fluidized bed, and effectively prolong the lifetime of the fluidized bed. Stabilization time to ensure sufficient reaction time between the material and chlorine gas; in addition, the lower part of the boiling chamber is equipped with an air distribution chamber, and the air distribution chamber is equipped with a hood casing with rectification holes, and the hood casing connects the gas distribution chamber and the boiling chamber; The hood casing is equipped with a double-channel spiral piece to realize high-intensity rotary cutting and agitation of the material bed, so that the material and chlorine gas can be fully mixed and reacted; further, a plasma gun ignition device is also installed in the fluidized fluidized furnace system to fully realize the titanium tetrachloride gas. High efficiency and fully automatic clean production.

Description

technical field [0001] The invention relates to a fluidized chlorination furnace chemical production device system, in particular to a fluidized furnace device system suitable for chlorination of high calcium magnesium titanium slag. Background technique [0002] At present, using titanium-rich materials such as titanium slag, rutile, and artificial rutile (main component: TiO 2 ) through high temperature chlorination reaction to produce titanium tetrachloride (TiCl 4 ), is the main process route for the production of titanium tetrachloride. However, industry technology research and production practice show that the large-scale boiling chlorination process has higher requirements on the content of impurities such as CaO and MgO in titanium-rich raw materials. Titanium-rich materials (high calcium magnesium titanium raw materials) with CaO+MgO content exceeding 1.5% are Difficult to use in boiling chlorination furnace with sieve plate. my country's Panxi region is rich in ...

Problems solved by technology

[0008] So far, no matter whether there is large-scale boiling chlorination technology of sieve plate in the world or in China, there is no Panxi titanium slag (the main component is TiO 2 =75~85%, CaO>1.5%, MgO>5%, the present invention is referred to as "high-calcium-magnesium-titanium slag") as a successful precedent of normal production of titanium tetrachloride as raw material
