Abstract

The invention discloses furnace slag granulating equipment for a vanadium-titanium magnetite blast furnace. The furnace slag granulating equipment comprises an outer box body and a plurality of high-pressure water guide pipes, wherein the front end of the outer box body is provided with flow spraying openings, and the high-pressure water guide pipes are horizontally arranged in the outer box body side by side; spiral flow guide grooves are formed in the inner walls of the high-pressure water guide pipes, high-pressure water guide cavities allowing high-pressure water to pass through are formed in the inner walls of the high-pressure water guide pipes, and the high-pressure water guide cavities are connected with an external high-pressure water source; the inner wall of the outer box body and the outer walls of the high-pressure water guide pipes form a high-pressure air flow guide cavity for high-pressure gas to pass through, and the high-pressure air guide cavity is connected with an external high-pressure gas source; and the front ends of the high-pressure water guide pipes are provided with water outlets located in the rear parts of the flow spraying openings, mixed flow cavities for mixing the high-pressure water and the high-pressure gas are formed between the water outlets and the flow spraying openings, and a plurality of concave parts are formed on the inner wall, close to the flow spraying openings, of the outer box body. The furnace slag granulating equipment has the advantages that water-gas mixing efficiency is higher, and the slag granulation rate is higher.

Description

technical field [0001] The invention relates to the field of slag granulation equipment, in particular to a slag granulation equipment for a vanadium-titanium magnet blast furnace. Background technique [0002] Vanadium-titanium magnetite is an important mineral resource. It is not only an important type of iron ore, but also the main carrier of vanadium-titanium resources. During the blast furnace smelting process of vanadium-titanium magnetite, due to various unstable factors of vanadium-titanium ore blast furnace slag, it is very difficult to select the type of slag treatment equipment, which has not yet reached a satisfactory level. [0003] Chinese patent number: CN201320277085.9, announcement number: CN203360462 U, patent name: a slag granulation device for a blast furnace for smelting vanadium-titanium magnetite, and discloses "a slag granulation device for a blast furnace for smelting vanadium-titanium magnetite, It is composed of an outer box and an inner box. The ...
