Mixed aerial fog steel slag treatment device

Abstract

The invention relates to steel slag treatment, and provides a mixed aerial fog steel slag treatment device. The mixed aerial fog steel slag treatment device comprises a slag box, a chute and a dust collector. The dust collector communicates with a chamber of the slag box. The mixed aerial fog steel slag treatment device further comprises an air inlet channel, a water inlet pipe and a first fog spraying pipe. The air inlet channel and the water inlet pipe both communicate to the first fog spraying pipe. The spraying-out path of the first fog spraying pipe intersects with the sliding-out path ofthe chute. A reflection plate allowing steel slag impacting is arranged in the slag box. According to the mixed aerial fog steel slag treatment device, molten red slag is crushed many times in a molten state, the particle size is smaller than the particle size of air quenching method slag treatment, the crushing quantity of subsequent treatment is reduced, even direct application is achieved without secondary treatment, and the subsequent investment and energy consumption are reduced. After the molten red slag is crushed in the molten state, free calcium oxide in the molten red slag is in full contact with aerial fog and steam obtained through aerial fog conversion to be eliminated, elimination of the free calcium oxide is more thorough and faster than elimination of hot stewed slag, theproblem about stability of tail slag is solved more thoroughly, and reutilization of the tail slag is facilitated.

Description

technical field [0001] The invention relates to steel slag treatment, in particular to a mixed gas mist steel slag treatment device. Background technique [0002] With the development of my country's iron and steel industry and the increase in demand for iron and steel, the discharge of metallurgical slag, especially blast furnace slag and steel slag, as a by-product in the iron and steel production process, has also increased year by year. The traditional air quenching method of steel slag treatment has the advantages of small footprint, low investment, fast processing speed, and small particle size of the slag after treatment; the traditional thermal braising method occupies a large area, requires a large investment, and has a relatively larger particle size than the air quenching method. However, they have their own shortcomings at the same time. The wind quenching method is to drop the steel slag into water to cool down and dissolve it. The disadvantage is that although ...
