大唐多伦58000m~3/h空分设备空压机放空管道改造

大唐多伦58000 m3/h空分设备运行过程中,空压机防喘振放空阀反应迟缓,导致空压机卸载和空分设备紧急停车。防喘振放空阀移位并取消相应联锁后,问题解决。但随后出现了放空管道开裂破损现象,改造放空管道后此现象消失。简述空分设备配套空压机组的结构和主要技术参数,详细介绍空压机防喘振放空阀及放空管道出现的问题,阐述原因分析过程、处理措施及其效果。

Reform of venting pipeline of air compressor of Datang Duolun 58000 m~3/h air separation plant

During run of Datang Duolun 58000 m3/h air separation plant,the slow response of anti-surge venting valve of the air compressor results in unloading of air compressor and urgent shutdown of air separation plant.The trouble is eliminated through shifting of the anti-surge venting valve and canceling corresponding interlocks,however,then after,the venting pipeline is subjected to crack and damage.The said problem is also solved through reforming of the venting pipeline.The structure and main technical parameters of air separation plant-completed air compressor set are briefed,the troubles occurring in air compressor anti-surge venting valve and venting pipeline are detailed,and the cause analysis process,the corrective measures and their effects are described.
