石油天然氣管道泄漏在線監(jiān)測報(bào)警裝置,是根據(jù)我國石油天然氣管道鋪設(shè)情況,特別是天然氣管道鋪設(shè)經(jīng)過人員密集區(qū)村鎮(zhèn)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(zāi)害,容易導(dǎo)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(qū)管道經(jīng)過的區(qū)域,在管道焊疤和管道連接處安裝石油天然氣泄漏在線監(jiān)測報(bào)警裝置,該裝置通過太陽能供電,陰天可連續(xù)供電15天以上,智能紅外天然氣泄漏監(jiān)測報(bào)警儀安裝于測點(diǎn)堰井,堰井采用雙紅外探頭設(shè)計(jì),檢測信號(hào)通過GPRS全網(wǎng)通模塊發(fā)送到管道局監(jiān)控平臺(tái),一旦檢測到微量泄漏,測點(diǎn)現(xiàn)場會(huì)立即啟動(dòng)高分貝防爆聲光報(bào)警器,提醒周邊群眾疏散至有效距離外,報(bào)警信號(hào)同時(shí)通過GPRS無線方式發(fā)送到沿途管道局平臺(tái),平臺(tái)通過及時(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(xiàn)場排查檢修,從而避免事態(tài)進(jìn)一步擴(kuò)大,和產(chǎn)生爆炸的危險(xiǎn)。
