PURPOSE: A device for preventing inflow of external air in exhaust gas recovery equipment of a converter is provided to doubly block external air flowing in through a gap between a hood and a skirt, thereby stabilizing the components of exhaust gas during work. CONSTITUTION: A device for preventing inflow of external air in exhaust gas recovery equipment of a converter comprises a lining part(150) formed at the top of a skirt(140) to block the space between a hood(120) and the skirt, a nitrogen header(160) which is installed on one end of the lining part stores nitrogen through a nitrogen supply line, and a nitrogen spray nozzle which is connected to the nitrogen header and sprays nitrogen to the nitrogen header to form a shield layer inside the lining part. |
