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。 Datang Duolun 58000 m3 / h air separation plant operation process, air compressor anti-surge vent valve slow response, resulting in air compressor unloading and air separation plant emergency stop. Anti-surge vent valve shift and cancel the appropriate interlock, the problem is solved. However, there was a phenomenon of cracking of the vent pipe and the phenomenon disappeared after the vent pipe was renovated. The structure and main technical parameters of the air compressor supporting air compressor are briefly introduced. The problems of air compressor anti-surge vent valve and vent pipe are introduced in detail. The reason analysis process, treatment measures and effects are explained.
