Definitions
- the invention relates to a method for granulating slag, in particular from a blast furnace and / or a smelting reduction plant, wherein a granulate-water mixture formed during granulation is fed to a granulation vessel and then to a dewatering plant in which the slag granules are dehydrated, and wherein the Granulating resulting H 2 S-containing vapors and gases are at least partially condensed in a congruent with the Grenulier disposer condensing space by injecting water.
- the air introduced into the system leads in other plant areas according to DE 35 11 958 C to a slight overpressure and passes through Granulatabsch- and other openings as well as over covers in the atmosphere. With the air, however, the harmful gases in concentrations that are above the permitted limits escape uncontrolled into the atmosphere.
- an overpressure is set in the granulating container and in the condenser space below the water injection. This is done by setting the water injection.
- the overpressure has the positive effect that the H 2 S-containing residual gases without forced delivery devices, such as fans and the like., Are passed to the downstream combustion point, ie slag trough.
- the amount of air introduced into the granulator reduces the amount of air and H 2 S cargo discharged from the system.
- the sulfur-containing vapors and gases produced during granulation are precipitated in a condensing tower 10 arranged above the granulation container 4.
- a device 11 for water injection is arranged, which is supplied via a fed from the collecting tank 23 water supply 12 with calcium oxide-containing water.
- a means 13 for collecting water and condensate e.g. formed by water gutters, arranged, which upper a discharge line 14 is connected to the water basin 7c.
