Description

Dust excluding hood device is handled to slag

Technical Field

The utility model relates to the technical field of environmental management, in particular to a steel slag treatment dust hood device.

Background

The steel slag is a complex substance formed by products of chemical reaction in the steel-making process, various slag-making materials and other materials. It is composed of various oxides formed by oxidizing impurities in pig iron, such as silicon, manganese, phosphorus, sulfur, etc. in the smelting process, and salts generated by the reaction of these oxides and solvent. Steel slag contains a plurality of useful components: mainly consists of 2 to 8 percent of metallic iron, 40 to 60 percent of calcium oxide, 3 to 10 percent of magnesium oxide, 1 to 8 percent of manganese oxide and silicate, so the iron-steel composite material can be used as a ferrous metallurgy raw material. The mineral composition of the steel slag is mainly tricalcium silicate, and then dicalcium silicate, RO phase, dicalcium ferrite and free calcium oxide. The steel slag is clinker, is a remelted phase and has low melting temperature. When re-melting, the liquid phase is formed early and the fluidity is good. The steel slag includes 3 kinds of electric furnace steel slag, open-hearth steel slag and converter steel slag.

The mainstream process of the steel slag treatment process comprises a hot splashing method, a hot stewing method, a roller method, a wind quenching method and the like. Among them, hot pour method and hot stuffiness method are the most commonly used. The method comprises the steps of pouring steel slag into a slag discharging tray from a steel making furnace, transporting the slag tray from a steel making span to a steel slag processing span by a slag tray vehicle, then hoisting the steel slag into a slag stewing pit by a slag spanning crane, circulating back and forth through slag dumping, water spraying/slag dumping and slag dumping, covering the slag pit when the slag pit is arranged at a specified position, carrying out water spraying cooling treatment on the slag, digging out the steel slag by an excavator after cooling is finished, and carrying out secondary treatment. In the treatment process, a large amount of steam and dust are generated in the steel slag treatment workshop, the dust is small in particle size, easy to scatter, high in moisture content, large in dust viscosity, dispersed in discharged state and high in collection difficulty, and most of steel slag treatment workshops cannot effectively collect the dust and the steam at present.

In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
