| description | The utility model provides a gas curtain sealing device for a fire hole of a coke oven. The gas curtain sealing device comprises a fire hole in a coke oven body and is characterized in that the upper and lower two ends of the fire hole are respectively provided with a knife-edge gas curtain nozzle, and the knife-edge gas curtain nozzles are connected with a main nitrogen delivery pipe respectively through branch nitrogen delivery pipes. By means of arranging the knife-edge gas curtain nozzles in the upper end and the lower end of the fire hole of the coke oven respectively, a nitrogen gas curtain with better sealability is formed at the fire hole, so that smoke can be effectively prevented from overflowing outwards from the fire hole, meanwhile, the sealing safety is improved by using inert gas, namely nitrogen, as a gas curtain medium, and accidents caused by mixing of high-temperature smoke and air are prevented effectively. |
