Efficient long-service-life blowing method and system for vanadium extraction-decarburization duplex converters
An efficient long-service-life blowing method include the steps of introducing vanadium extraction converter flue gas and decarburization converter flue gas into an oxygen combustor; obtaining first-purity CO2—N2 mixed gas through the vanadium extraction converter flue gas; obtaining second-purity CO2—N2 mixed gas through the decarburization converter flue gas; obtaining O2—CO2—N2 mixed gas through the decarburization converter flue gas; obtaining first-purity CO2 gas through the second-purity CO2—N2 mixed gas; and using the first-purity CO2—N2 mixed gas for bottom blowing of the vanadium extraction converter, using the second-purity CO2—N2 mixed gas as a carrier gas for blowing iron ore powder into the vanadium extraction converter, and using the O2—CO2—N2 mixed gas and the first-purity CO2 gas as a carrier gas for bottom blowing of the decarburization converter and bottom injecting of lime powder into the decarburization converter.
