Description

Water slag filtering and lifting environment-friendly device for steel mill

Technical Field

The utility model belongs to the environmental protection field is handled to ironmaking grain slag, specifically is a water slag filters promotes environment-friendly device for steel mill.

Background

The granulated slag is a byproduct generated in blast furnace ironmaking, and is mainly used for manufacturing building materials after processing; in the production process of the blast furnace, after various raw materials and fuels entering the furnace are smelted, molten iron (steel-making pig iron or casting pig iron) and blast furnace gas as a byproduct are obtained, gangue in the iron ore and ash in the fuel are fused with a flux to form liquid slag, the liquid slag generally has the temperature of 1450-1550 ℃, and is discharged from a slag hole and an iron hole at regular time; the slag discharged from the slag hole is generally called "upper slag", the slag discharged from the taphole together with the molten iron is called "lower slag", and a small amount of molten iron is often mixed in the lower slag; the blast furnace slag mainly comprises CaO, MgO, SiO2 and Al2O3, which account for more than 95% of the total amount, and the 4 components can basically determine the metallurgical performance of the blast furnace slag. A large amount of blast furnace slag is transported to a slag disposal site as waste by a slag pot car, the treatment method is long-lasting, occupies a large area, pollutes the environment, has high operation and management cost, and often expands balls and the like in time due to untimely allocation of the slag pot, thereby influencing the on-time slag discharge and iron tapping of the blast furnace.

Due to the development of comprehensive utilization of blast furnace slag, blast furnace slag is mostly quenched into water slag, which becomes a raw material for making slag cement or slag brick, and can also be used for making slag wool, cast stone, expanded balls and the like. In order to recover the heat energy of the slag, reduce the water consumption and reduce the sulfide emission, a great deal of research on dry-process or water-less slag granulation technology has been carried out in all countries in the world since the eighties of the last century, but the practical degree is not reached so far, and it is estimated that the water quenching treatment of the blast furnace slag is still the mainstream process at least in the next years, so how to treat the water slag is still a relatively long research direction.

The traditional scarfing cinder method is at delivery port installation filter screen, then clears up the granulating slag through manual operation grab bucket, and the main problem of this kind of method is, the dross is difficult for snatching in the pond, if the filter screen scarfing cinder is not timely, then leads to the mesh to block up easily, brings very big hidden danger for subsequent hydrologic cycle technology, and simultaneously, the workman must the site operation grab bucket, intensity of labour is big, and work efficiency is low, consequently, need to develop new granulating slag and filter promotion environment-friendly device urgently.
