Take care not to let the gas in the tube blow back. 当心别让管子里的煤气倒燃(爆炸)。
Dedusting Blast Furnace Gas by Means of Off-Line Pulse Blow - Back Dedusting Technique 离线脉冲喷吹除尘技术在高炉煤气除尘上的应用
At present, blast furnace bag type dusters usually use gas pressuring back blow dedusting system. Nitrogen pulse back blow dedusting system used for gas dry dedusting in large and middle-sized blast furnaces is in the experimental stage. 目前高炉袋式除尘器基本采用煤气加压反吹清灰系统,氮气脉冲反吹清灰系统用于大中型高炉煤气干法除尘尚处于试验阶段。
A comparison of advantages and disadvantages is made between the gas pressuring back blow duster and the nitrogen pulse back blow duster. 对比了煤气加压反吹除尘器与氮气脉冲反吹除尘器的优缺点。
