OXYGEN-ENRICHED SINTERING FLUE GAS CIRCULATION SYSTEM AND APPLICATION THEREOF

WIPO Patent Application WO/2021/072814

A1

The present application relates to an oxygen-enriched sintering flue gas circulation system and an application thereof. The oxygen-enriched sintering flue gas circulation system comprises a sintering machine, a first dust remover, a first fan, an oxygen addition system, a second dust remover, a second fan, and a post-processing unit. The oxygen addition system uniformly mixes oxygen with a circulating flue gas, ensuring the stability of the sintering yield and quality. A detection unit detects the oxygen content in the circulating flue gas in real time to adjust the oxygen addition amount by means of a control unit, and detects the oxygen content in the mixed flue gas in real time to feed back and adjust a flow adjustment device by means of the control unit, enabling the oxygen content of the circulating flue gas to be 18% to 30%.
