Abstract
In a process for granulating slag, from a blast furnace or a smelting reduction plant, in which a granule/water mixture formed during the granulation is fed to a granulation tank and then to a dewatering installation, in which the slag granules are dewatered. H2S-containing vapors and gases formed during the granulation are at least partially condensed by injection of water in a condensation space which is flow-connected to the granulation tank. H2S-containing residual gases are discharged from the compensation space below the water injection point, H2S is burnt.
Claims13
An installation for granulating slag from a blast furnace or a smelting reduction plant, comprising
- a granulation device, a slag channel for delivering the slag to the granulation device, a downstream granulation tank downstream from the granulation device for holding a granule/water mixture, a condensation device, which is flow-connected to the granulation tank, a water feed including a device for injecting water into the condensation device, and a subsequent granule dewatering installation,
- a discharge line from the condensation device for discharging vapors and gases a combustion chamber pipe-connected to the discharge line and provided in the condensation device connected below the device for injecting water.
An installation for granulating slag, a blast furnace or a smelting reduction plant, comprising
- a granulation device, a slag channel for delivering the slag to the granulation device, an extractor hood over the slag channel, for a downstream granulation tank down stream from the granulation device for holding a granule/water mixture, a condensation device, which is flow-connected to the granulation tank, a water feed including a device for injecting water into the condensation device, and a subsequent granule dewatering installation,
- a discharge line from the condensation device for discharging vapors and gases, the discharge line opening out into the slag channel between the granulation device and the extractor hood, the discharge line is provided in the condensation device connected below the device for injecting water.
