Problems solved by technology

[0002] At present, domestic and foreign chlorination methods mostly use boiling chlorination furnaces with sieve plates. The advantages are that the fluidized bed in the furnace is stable, easy to control, simple in equipment, and easy to make. Ditching makes the production index worse, and even forced to shut down the furnace, so the requirements for titanium-containing materials (natural rutile, artificial rutile, high-titanium slag, etc.), especially the requirements for calcium and magnesium impurities are relatively high
my country is a country with rich titanium resources. 95% of titanium ore is rock ore, which contains hi

Embodiment 1

[0012] Fig. 1 is the sectional view of multilayer flow fluidized chlorination furnace without sieve plate of the present invention, and the furnace body of chlorination furnace is garden column and garden cone, is made up of outer steel shell 16 and furnace lining 17 of liner refractory material, furnace cover 5 It is an inverted cone, and the furnace cover 5 is equipped with a gas outlet 6, an explosion-proof port 7, and a temperature measuring port 8. The connection between the furnace cover 5 and the furnace body is a self-weight compression connection, and the joint is sealed with a refractory gasket 9. The furnace body It can be divided into four sections from bottom to top. The first furnace section 1 is conical, with a temperature measuring port 29 on its upper part, and a flange 11 and a flange 14 on the furnace bottom fastened to the furnace bottom 13 by bolts. Connection, there is an elastic sealing ring 12 between the flange 11 and the flange 14 of the furnace bottom...

Abstract

The invention discloses a furnace with four segments, which is characterized by the following: the flannel (11) on the bottom of first furnace segment connects base flannel (14) with furnace base (13) through bolt, the second furnace segment (2) is conical, the third furnace segment is conical, the forth furnace segment (4) is column, the furnace base (13) is integral three-layer chlorine reserving structure, whose bottom board steel board (28) possesses cone chlorine reserving chamber of fireproof concrete, the chlorine inlet and outlet are opened on the chlorine reserving chamber, which is distributed at ring shape, the chlorine inlet connects chlorine pipe with each chlorine pipe allocating chlorine flow self-adjusting tool (24), the discharge hole (15) is set on the center of furnace base (13).

Description

technical field [0001] The invention relates to the preparation of titanium tetrachloride, in particular to a boiling chlorination furnace. Background technique [0002] At present, domestic and foreign chlorination methods mostly use boiling chlorination furnaces with sieve plates. The advantages are that the fluidized bed in the furnace is stable, easy to control, simple in equipment, and easy to make. Channeling will deteriorate the production index and even force the furnace to be shut down. Therefore, the requirements for titanium-containing materials (natural rutile, artificial rutile, high-titanium slag, etc.), especially the requirements for calcium and magnesium impurities are relatively high. my country is a country with rich titanium resources. 95% of titanium ore is rock ore, which contains high impurities such as magnesium and calcium. The high-titanium slag produced by electric arc furnace smelting generally contains 7-10% Mgo+Cao, and is produced in the chlori...
