Abstract

The invention relates to a processing device and technique for molten iron of a titanium slag smelting by-product. The device comprises a molten iron trolley, a granulating system, a high-temperature collection tower, an iron powder cooler, a control system and a collection transferring system. The molten iron trolley is arranged on a track and can be driven by a motor to move linearly on the track so as to carry and transport the molten iron. The granulating system is located under the molten iron trolley and can be driven by a high-speed rotary motor to achieve centrifugal granulating of the molten iron. The high-temperature collection tower is located at an outlet of the granulating system and used for collecting high-temperature solid iron powder particles. The high-temperature collection tower is connected with the iron powder cooler used for cooling the high-temperature solid iron powder particles. The iron powder cooler is connected with a cold state collection system. According to the processing technique, the molten iron flows out of the molten iron trolley and enters the granulating system; and the molten iron is granulated into ellipsoidal or spherical particles which are cooled in the flying process in the collection tower, and cold state iron powder is collected. The product additional value of the molten iron of the titanium slag smelting by-product is increased.

Description

technical field [0001] The invention relates to a treatment system for molten iron, in particular to a treatment equipment and process for molten iron, a by-product of titanium slag smelting. Background technique [0002] High-titanium slag is ilmenite concentrate heated and melted by an electric furnace, and it is a concentrated product of titanium dioxide obtained after melting and separating titanium dioxide and iron in ilmenite concentrate. High-titanium slag is neither mineral waste nor a by-product formed in the production process, but a high-quality raw material for the production of titanium tetrachloride, titanium dioxide and titanium sponge by sulfuric acid method and chlorination method. [0003] Foreign titanium dioxide production enterprises, the sulfuric acid process and the chlorination process coexist. However, almost all domestic titanium dioxide production enterprises use the sulfuric acid process. The main chemical reactions in the sulfuric acid titanium...
