The invention relates to a converter fume high-temperature bag dust removal and recycling and secondary steam recycling
system, which comprises a converter, a vaporizing
flue cooling device, a high-temperature bag
dust collector, an exhaust-heat boiler, a speed regulation fan, a switching valve
station, a diffusing
chimney, a
gas cooling tower, a plurality of glasses valves, a dust
output device and a dust storage bin. The high-temperature bag
dust collector performs purification treatment on the fume till the temperature of 800 DEG C at an opening of the vaporizing
flue; the exhaust-heat boiler is arranged at the opening of the high-temperature bag
dust collector for performing the secondary recycling of the steam. The exhaust-heat boiler is connected with the speed regulation fan; an outlet of the speed regulation fan is connected with the switching valve
station, the diffusing
chimney and the glasses valves and then connected with the
gas cooling tower. The
gas cooling tower is arranged in front of an inlet of a
gas chamber. Due to the adoption of the converter fume high-temperature bag dust removal technology and the recycling of the secondary high-temperature fume
exhaust heat (secondary steam recycling) below 800 DEG C, the purification efficiency of the fume is high, the
system operates safely and stably, the
energy consumption is low, the recycled amount of the steam and gas is high, the
system blockage and secondary
water pollution are absent, and the
negative energy steel-making and
continuous casting are realized.
