<p>An equipment for exhausting waste gas of a coke oven, which prevents heat loss of the coke oven and prevents damage of facilities within the coke oven due to thermal shock by flowing air of a high temperature into the coke oven and improves working environment and prevents breakdown of the facilities due to thermal expansion by flowing air around the equipment into the coke oven, is provided. An equipment for exhausting waste gas of a coke oven comprises: an exhaust pipe connected to a circulation path(11) installed below the coke oven; an air inflow part(20) installed on an outer surface of the exhaust pipe; a waste gas valve damper(30) which is connected to the exhaust pipe, and on which a blocking member for opening or closing the exhaust pipe; and a small flue(40) connected to the waste gas valve damper. The blocking member comprises an air blocking plate(34) and a waste gas blocking plate(36) installed above the air blocking plate. The air inflow part comprises a cover plate for controlling inflow of air and an air inflow part chain(23) for operating the cover plate. The equipment further comprises a reversing bar(50) installed on an upper portion of the waste gas valve damper to adjust opening and closing of the waste gas valve damper and the air inflow part. The waste gas valve damper comprises a waste gas valve damper chain(38) of which one end is fixed to the blocking member, and of which the other end is fixed to the reversing bar.</p> |
