带报警装置爆破片在高含硫天然气放空系统中的应用

APPLICATION OF RUPTURE DISC WITH ALARM DEVICE IN HIGH SULFUR GAS BLOWOUT SYSTEM

高含硫天然气生产现场常见爆破片等安全保护装置,标准中规定爆破片更换周期2-3年,期间爆破片破裂难以及时发现,给安全生产带来隐患。基于姜一昌、温殿江等人设计的一种爆破片运行状态监测装置理论研究,在爆破片环缝圆板上设计1根固定报警导线,爆破片破裂时环缝圆板张开将其上固定的报警导线拉断,通过信号远传让操作人员及时发现爆破片破裂,从而第一时间更换爆破片。现场应用表明:带报警装置爆破片能够让值班室操作人员迅速发现爆破片破裂并及时更换爆破片,可有效预防长明火场站的火源通过破裂的爆破片越过阻火器进入气田水罐,防止安全生产事故的发生,对长明火和阻火器易堵塞的高含硫场站具有一定的推广应用价值。

Safety protection devices such as rupture discs are common in the production site of high-sulfur natural gas.According to the standard,the replacement cycle of rupture discs is 2 to 3 years,during which it is difficult to detect the rupture of the discs in time,bringing hidden dangers to safety in production.Based on the theoretical research of a monitoring device for the operation state of the rupture disc designed by Jiang Yichang,Wen Dianjiang et al.,a fixed alarm wire is designed on the circular plate of the rupture disc.When the rupture disc breaks,the circular plate of the rupture disc opens and the fixed alarm wire on the circular plate of the rupture disc will be broken.And the signal remote transmission allows the operator to detect the broken rupture discs in time and replace them as soon as possible.The field application indicates that the rupture disc with alarm device can make the duty room operators quickly discover the rupture disc and replace it in time,which can effectively prevent the fire source of pilot flame station from entering the gas field water tank through the broken rupture disc,and prevent work safety accidents.It is of certain value to promote the application in high sulfur stations with pilot flame and flame arresters prone to be blocked.
