【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、四塩化チタン等の製造に使用される流動層塩

を用いて説明する。Conventionally, titanium tetrachloride has been produced by reacting a titanium-containing raw material with chlorine gas in a fluidized bed chlorination furnace. The structure of the fluidized bed chlorination furnace for producing titanium tetrachloride will be described with reference to FIG.

する。塩素ガスはチタン含有原料４を流動化する過程で
四塩化チタンに転化し炉頂口６より取出される。A refractory material is lined inside the metal case 1 in order to prevent the metal case 1 from being chemically and physically damaged due to a fluidized bed reaction caused by chlorine. This refractory is constructed by stacking refractory bricks 2 in a mosaic shape and filling the gaps between the refractory bricks 2 with mortar 3. Then, while the titanium-containing raw material 4 is charged into the furnace, chlorine gas is blown from the furnace bottom opening 5 to fluidize the titanium-containing raw material 4. Chlorine gas is converted into titanium tetrachloride in the process of fluidizing the titanium-containing raw material 4 and taken out from the furnace top port 6.
ところが、この流動層塩化炉においては、従来より塩素
ガスの一部が流動層を通過せずに周囲の耐火物を通って
炉外へ排出されるという問題があった。これは耐火物
間、あるいは金属製ケース１と耐火物との間に生じる間
隙が原因である。However, in this fluidized bed chlorination furnace, conventionally, there has been a problem that a part of chlorine gas is discharged to the outside of the furnace through the surrounding refractories without passing through the fluidized bed. This is due to the gaps formed between the refractory materials or between the metal case 1 and the refractory material.

パスを発生させる。That is, when a refractory material is lined inside the metal case 1, a gap is inevitably formed especially in the portion of the mortar 3 ′ that is in contact with the metal case 1 due to deformation or the like accompanying reuse of the metal case 1. Since the mortar 3 is more easily corroded than the surrounding refractory bricks 2, by repeating the fluidized bed reaction, the mortar 3 between the refractory bricks 2 is preferentially corroded from the inside of the furnace to generate a gap. Then, when this gap is connected to the gap that originally exists in the mortar 3 that is in contact with the metal case 1 described above, a so-called short path in which chlorine gas escapes to the upper part of the chlorination furnace without passing through the fluidized bed is generated.

耗腐食され通常予期される寿命に反して極めて短寿命で
あった。このため塩化炉の耐火物の張り代えを余儀無く
され、経済性を著しく悪化させているのが実状である。This short-passing chlorine gas becomes unreacted chlorine, significantly reducing the reaction efficiency of the furnace. Further, not only chlorine but also CO which is a reducing gas or titanium raw material ore and coke particles which are fluidized bed components enter the short path. As a result, the refractory brick 2 and the mortar 3 were significantly worn and corroded, and had a very short life contrary to the normally expected life. For this reason, refractory materials in the chlorination furnace have to be replaced, and the economic efficiency is considerably deteriorated.
本考案は斯かる状況に鑑み、塩素ガスのショートパス並
びにそれに伴う未反応塩素の発生及び炉寿命の短縮を防
止し得る流動層塩化炉を提供することを目的とする。In view of such a situation, an object of the present invention is to provide a fluidized bed chlorination furnace capable of preventing a short path of chlorine gas, generation of unreacted chlorine due to the short path, and shortening of the furnace life.

The gap 7 existing around the refractory lining is characterized by being filled with a resin 9.

実現される。For resin injection, resin injection port 8 provided in metal case 1
As a result, the injected resin 9 preferentially fills and solidifies and seals the gap 7 at the portion of the mortar 3 of the refractory lining, especially the portion in contact with the metal case 1. Therefore, even if there is corrosion due to chlorine from the inside of the furnace in the portion of the mortar 3 between the refractory bricks 2, or even if the gap 7 due to this corrosion reaches the mortar 3'which is in contact with the metal case 1. The short path is not reached all at once, and unreacted chlorine is generated and the life of the furnace is extended.

Refractory brick 2 is 2 for the bottom of the furnace, which is in frequent contact with charging material 4.
There is a single-ply structure near the upper part and the upper part. Mortar 3'between the metal case 1 and the refractory brick 2

A large number of resin injection ports 8 are provided on the outer periphery of the metal case 1, and a thermosetting resin 9 is press-fitted from the resin injection port 8 in a heated liquid state. The resin 9 that has been press-fitted fills the gap 7 existing in the mortar 3'between the metal case 1 and the refractory, while the gap 9 existing in the mortar 3 between the refractory bricks 2 is filled, as shown in FIG. It is also filled in 7 and solidifies as the temperature decreases.
