摘要:

低压氨水主要用于焦炉荒煤气冷却,一旦停供将对焦炉生产造成严重影响,焦炉低压氨水阀门更换作业具有较大风险,特别是主管阀门更换比较困难。介绍了一种不停产更换低压氨水主管阀门的方法,可以保证在低压氨水阀门更换过程中集气管温度在可控范围内波动,有效避免了更换过程中可能产生的荒煤气放散及荒煤气导出设备损坏事故。

Abstract:

The low pressure ammonia liquor is mainly used for cooling crude coke oven gas,once it is cut off,the production would be seriously affected.The replacement of the LP ammonia liquor valve is very risky,in particular more difficult for replacing the main pipe valve.In this paper,a method of on-line replacing LP ammonia liquor valve is introduced,which not only ensures the GCM temperature is controllable in fluctuation,but also effectively avoids potential bleeding of crude gas and avoids damage to crude gas transferring device during the replacement.

Key words: Coke oven, LP ammonia liquor, Main pipe valve, Crude coke oven gas, GCM ,
