Problems solved by technology

[0004] The defects of the prior art treatment process are low separation degree of slag and iron and long cooling period
In addition, a large amount of water needs to be consumed to cool the high-temperature desulfurization slag during the treatment process, and a large amount of water vapor and smoke are generated at the same time, which not only wastes resources but also pollutes the environment

Abstract

The invention discloses a general structure of a slag and iron separation and cooling device for molten iron desulphurization slag. The device is configured according to two modes, namely an off-line treatment mode and an on-line treatment mode; when the device is configured according to the off-line treatment mode, a lifting tip-over device and a slag tank are arranged; and when the device is configured according to the on-line treatment mode, an on-line moving device is arranged. By the adoption of the technical scheme, full separation of slag from iron can be realized, and the slag and the iron can be quickly cooled, thus realizing quick and continuous industrial production; one process comprises two use or configuration modes; under both the on-line treatment mode and the off-line treatment mode, a core technology in the treatment process is consistent with that of equipment; conversion between the two working modes can be quickly realized, so as to meet use requirements of different occasions, fulfill the aims of wide use range, flexible equipment configuration and simple maintenance, improve the treatment efficiency and reduce the investment cost.

Description

technical field [0001] The invention belongs to the field of desulfurization slag treatment technology and equipment manufacturing in molten iron pretreatment. More specifically, the present invention relates to the overall structure of a slag-iron separation and cooling device for on-line or off-line processing of molten iron desulfurization slag, which can efficiently perform slag-iron separation and cooling treatment on high-temperature desulfurization slag. Background technique [0002] At present, in the smelting industry, the treatment of desulfurization slag mostly adopts the treatment method of spraying water to cool down and then crushing and separating. [0003] The desulfurization slag treatment process in the prior art is to arrange the slag tank at the desulfurization operation site, and the hot-melt desulfurization slag in the molten iron tank after the desulfurization operation is directly picked up from the molten iron tank into the slag tank by a slag remova...
