Abstract
PURPOSE: To provide a protecting apparatus for exhaust-gas-treating apparatus and to collect the dust efficiently at the time of blast furnace blow-bye, by cooling unusual high temp. gas with water spray and with water flowing along the wall.
CONSTITUTION: In normal operation of a protecting apparatus 6 described above, blast furnace exhaust gas is led 2 tangentially into a casing body 1, then the gas flows down helically and is separated from dust of large particle diameter. The exhaust gas having been separated from dust is discharged 3 to an exhaust gas treating apparatus of the blast furnace. When unusual high-temp. gas is generated because of flow-bye etc., the exhaust gas is cooled by spraying 4 water in a quantity not more than that cools the gas to the saturation temp. In addn., the exhaust gas is cooled by introducing 5 water to the inner wall surface of the casing 1. The exhaust gas thereby cooled is fed to the exhaust-gas-treating apparatus of the blast furnace. The quantity of the spraying water is controlled by a water spray control unit 13 according to the temps. at the blast furnace top and at the apparatus 6.
