石油天然氣管道泄漏在線(xiàn)監測報警裝置,是根據我國石油天然氣管道鋪設情況,特別是天然氣管道鋪設經(jīng)過(guò)人員密集區村鎮公路橋梁和涵洞時(shí),沿途管道經(jīng)常遭受重壓受損,也經(jīng)常遭遇泥石流沖擊等災害,容易導致焊疤和連接處產(chǎn)生漏氣,遇高溫明火極易產(chǎn)生爆炸。所以在人員密集區管道經(jīng)過(guò)的區域,在管道焊疤和管道連接處安裝石油天然氣泄漏在線(xiàn)監測報警裝置,該裝置通過(guò)太陽(yáng)能供電,陰天可連續供電15天以上,智能紅外天然氣泄漏監測報警儀安裝于測點(diǎn)堰井,堰井采用雙紅外探頭設計,檢測信號通過(guò)GPRS全網(wǎng)通模塊發(fā)送到管道局監控平臺,一旦檢測到微量泄漏,測點(diǎn)現場(chǎng)會(huì )立即啟動(dòng)高分貝防爆聲光報警器,提醒周邊群眾疏散至有效距離外,報警信號同時(shí)通過(guò)GPRS無(wú)線(xiàn)方式發(fā)送到沿途管道局平臺,平臺通過(guò)及時(shí)切斷沿途上下游閘閥,減小壓力等措施的同時(shí),立即安排現場(chǎng)排查檢修,從而避免事態(tài)進(jìn)一步擴大,和產(chǎn)生爆炸的危險。
