More Information
Summary:The utility model discloses a converter gas cooling device, which comprises at least two series-connected cooling sections (3), wherein a blast wall (6) is arranged between the adjacent cooling sections (3) and consists of a plurality of groups of mutually close water cooling pipes, and gaps between the water cooling pipes on the blast wall (6) are less than a propagation distance of the minimum flame after the converter gas is mixed with air; and the blast wall (6) can also be made from a heat resistant porous material, and an aperture is less than the propagation distance of the minimum flame after the converter gas is mixed with air. With the cooling device, the temperature of converter gas can be safely reduced to about 200 DEG C, water spraying or steam cooling are not needed, and the sensible heat of the converter gas can be recovered.
