Embodiment Construction

[0017] Such as figure 2 As shown, a steam thermal crushing device for iron slag includes a liquid slag storage tank 11, a powder slag collection tank 19, a powder slag transport tank 4, and a steam generating device. The slag outlet of the liquid slag storage tank 11 is connected through a liquid slag nozzle A powder slag collection tank 19, a powder slag transport tank 4 is arranged below the powder slag collection tank 19, a steam cooling tower 21 is connected above the powder slag transport tank 4, and a steam nozzle 7 is provided on the side of the liquid slag nozzle 8, and the steam cooling tower passes through the steam for its own use. The pipe 25 communicates with the steam vent 7 .

[0018] Such as figure 1 As shown, the working principle: After the liquid slag transport tank receives the iron slag, it is poured into the liquid slag storage tank, and the liquid slag flows out from the liquid slag nozzle located in the powder slag collection tank, and is broken by th...

Abstract

The invention relates to the field of steel and iron smelting waste heat recovery, in particular to an iron slag steam thermal crushing device and process, and the problem of iron slag waste heat recovery is solved. The iron slag steam thermal crushing device comprises a liquid slag storage tank, a powder slag collecting tank, a powder slag transportation tank and a steam generating device. The slag outlet of the liquid slag storage tank is connected with the powder slag collecting tank through a liquid slag nozzle, the powder slag transportation tank is arranged below the powder slag collecting tank, and a steam cooling tower is connected to the position above the powder slag transportation tank. A steam nozzle is formed in the side face of the liquid slag nozzle, and the steam cooling tower communicates with the steam nozzle through a self-service steam pipe. Nationwide sensible heat recovery of steel and iron slag converted into standard coal is about 16 million tons per year, the heat recovery effect is remarkable; and totally enclosed treatment is achieved, and dust pollution is avoided.

Description

technical field [0001] The invention relates to the field of iron and steel smelting waste heat recovery, in particular to an iron slag steam thermal crushing device and process. Background technique [0002] Most modern ironmaking uses blast furnace ironmaking. Blast furnace ironmaking is to directly reduce iron ore in a blast furnace and melt it into pig iron. This method is easy to operate, low in energy consumption, low in cost, and can be mass produced. The direct reduction ironmaking method is to reduce the ore in the solid state with a gas or a solid reducing agent. The raw materials and functions of the blast furnace ironmaking include (1) Iron ore: (sintered ore, pellets) to provide iron elements. Smelting One ton of iron needs about 1.5-2 tons of ore. (2) Coke: About 500Kg of coke is needed to smelt one ton of iron. Provide heat; provide reducing agent; Impurities, resulting in slag with good reactivity and appropriate quantity, need to add metallurgical fluxes su...
