Embodiment Construction

[0020] Embodiments of the invention: at first, TiO in natural rutile 2 The content is basically 96%, and the carbon content in metallurgical coke is basically 91.8%. The weight ratio of natural rutile to metallurgical coke is: 100:22.74. Since the price of natural rutile is higher, and metallurgical coke is cheaper, it can be considered to increase appropriately The amount of metallurgical coke is subjected to boiling chlorination. Before chlorination, metallurgical coke must be dried by hot air flow and then pulverized.

[0021] The production capacity of this system is 195,000 tons / year of crude titanium tetrachloride. In this way, when the natural rutile added to the chlorination furnace is 11476.08kg per hour, it is necessary to chlorinate with chlorine gas in the boiling chlorination stage, and the chlorine gas per hour is chlorinated. The amount of chlorine gas required for chemical purification is 20.848 tons.

[0022] After the boiling chlorination stage, the air volu...

Abstract

The invention provides a method for preparing coarse titanium tetrachloride. The method uses natural leucoxene as a raw material and metallurgical coke as a reducing agent to obtain the coarse titanium tetrachloride through the addition of chlorine for boiling chloridization, the cooling of a cyclone exhaust fan, atomization, the filtration of a cloth envelop collector and the absorption of a packed absorption tower. The invention has the advantages of expanding the sources used for producing the coarse titanium tetrachloride by using the natural leucoxene as a raw material, and removing slag and collecting titanium tetrachloride in a mixed furnace gas discharged from the top of a chlorination furnace. In the prior art, furnace slag produced during the production of titanium tetrachloride by using high titanium slag as a raw material is discharged from the bottom of the furnace, and the operation environment is severe and requires a gas mask for operation.

Description

Technical field: [0001] The invention relates to a method for preparing crude titanium tetrachloride. Background technique: [0002] At present, domestic production of crude titanium tetrachloride basically uses titanium slag or high-titanium slag as raw material. They all use ilmenite to smelt TiO in ilmenite in an electric furnace 2 The product obtained by enriching to a certain content. Usually TiO 2 The content greater than 90% is called high titanium slag, and TiO 2 The content less than 90% is called titanium slag, and the following are collectively referred to as high titanium slag. Since more than 90% of the titanium ore in the world is now used to produce titanium dioxide, the source of raw materials is increasingly tight. Moreover, each ton of high-titanium slag needs to consume more than 3,000 kilowatt-hours of electricity to obtain it. Now the TiO2 of high-titanium slag on the market 2 The content is basically no more than 90%, and the price is close to 4,0...
