根據現狀考察點火設備市場,決定采用新型高能點火器裝置。
高能點火器裝置的(de)點火(huo)槍火(huo)花能量大,具有自凈(jing)功能,防(fang)潮防(fang)雨(yu)設計,點火(huo)槍長度(du)大于2m,可使電(dian)纜(lan)及(ji)點火(huo)器裝(zhuang)置避免(mian)高(gao)溫輻射(she)、烘烤(kao),高(gao)壓電(dian)纜(lan)采(cai)用硅橡膠耐溫高(gao)壓線(180°C,20kV),高(gao)能點火(huo)器安裝(zhuang)在筒體底部,不易燒壞且檢修維護方(fang)便。
高能點火器裝置的點火原理與噴氣式飛機發動機低壓高能點火裝置相同,其20J點火裝置輸出電流達500mA,脈沖放電單個火花能量可達1.1J。所有在高溫區高壓輸出線路都采取陶瓷絕緣體(95n高鋁瓷管)隔離、采用不銹鋼管保護、及熱密封措施(稱為高壓導電桿),該結構耐高溫、耐腐蝕、防水防潮,點火電極之間鑲有高新材料一半導體材料,使點火電極具有自凈功能、不積碳、不結焦。這種獨特的優越性能是普通高壓點火器裝置所無法比擬的,因此更適用于高空點火。
同時(shi)采用(yong)(yong)紫(zi)外線火(huo)(huo)(huo)檢(jian)(jian)儀,檢(jian)(jian)測火(huo)(huo)(huo)炬點(dian)(dian)(dian)燃(ran)(ran)與否,即使肉眼看不到,也能靠火(huo)(huo)(huo)檢(jian)(jian)儀測量出點(dian)(dian)(dian)燃(ran)(ran)與否。自動點(dian)(dian)(dian)火(huo)(huo)(huo)系(xi)統由點(dian)(dian)(dian)火(huo)(huo)(huo)觸發信號(hao)(hao)源、點(dian)(dian)(dian)火(huo)(huo)(huo)控(kong)(kong)(kong)制(zhi)單元(yuan)、高空(kong)點(dian)(dian)(dian)火(huo)(huo)(huo)裝置、助燃(ran)(ran)氣、蒸汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥等(deng)幾大部分構(gou)成(cheng)。點(dian)(dian)(dian)火(huo)(huo)(huo)控(kong)(kong)(kong)制(zhi)單元(yuan)主(zhu)機采用(yong)(yong)PLC實現系(xi)統控(kong)(kong)(kong)制(zhi)。點(dian)(dian)(dian)火(huo)(huo)(huo)觸發信號(hao)(hao)來自于(yu)集(ji)氣管(guan)上的壓(ya)力信號(hao)(hao)和長(chang)明(ming)燈的火(huo)(huo)(huo)焰檢(jian)(jian)測信號(hao)(hao)。在(zai)集(ji)氣管(guan)上設有壓(ya)力變(bian)送(song)器(qi),壓(ya)力信號(hao)(hao)及火(huo)(huo)(huo)焰信號(hao)(hao)送(song)至程控(kong)(kong)(kong)系(xi)統控(kong)(kong)(kong)制(zhi)柜(ju)。程控(kong)(kong)(kong)點(dian)(dian)(dian)火(huo)(huo)(huo)系(xi)統控(kong)(kong)(kong)制(zhi)柜(ju)用(yong)(yong)于(yu)處理裝置放散高爐煤氣的自動點(dian)(dian)(dian)火(huo)(huo)(huo)。當(dang)集(ji)氣管(guan)壓(ya)力信號(hao)(hao)處于(yu)高位信號(hao)(hao)報警時(shi),電(dian)(dian)(dian)(dian)(dian)(dian)動執行器(qi)打開放散閥板(ban),同時(shi),點(dian)(dian)(dian)火(huo)(huo)(huo)助燃(ran)(ran)氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥及吹掃氨氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閱打開并(bing)延時(shi)關閉,點(dian)(dian)(dian)燃(ran)(ran)點(dian)(dian)(dian)火(huo)(huo)(huo)長(chang)明(ming)燈引燃(ran)(ran)主(zhu)火(huo)(huo)(huo)炬。當(dang)集(ji)氣管(guan)壓(ya)力信號(hao)(hao)處于(yu)低位信號(hao)(hao)報警時(shi),點(dian)(dian)(dian)火(huo)(huo)(huo)助燃(ran)(ran)氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥關閉,熄滅點(dian)(dian)(dian)火(huo)(huo)(huo)長(chang)明(ming)燈。同時(shi),打開滅火(huo)(huo)(huo)氨氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥并(bing)延時(shi)關閉,電(dian)(dian)(dian)(dian)(dian)(dian)動執行器(qi)關閉放散閘(zha)板(ban),主(zhu)火(huo)(huo)(huo)炬熄滅,延時(shi)關閉相應消煙蒸汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥。
通過壓力變送器的壓力信號,裝置程控系統可判斷是否有高爐煤氣排放,并根據長明燈的火檢信號判定是否發出點火指令,觸發高能點火裝置是否點燃長火,自動點火系統回到巡檢狀態。若長明燈熄滅,并且仍有高爐煤氣排放時,自動點火系統將重新點燃長明燈。如遇點火故障(有放空高位壓力信號,但長明燈未點燃)則發出聲、光報警信號,報警信號送至裝置程控系統。更多油田專用點火裝置,高能點火器,防爆高能點火器,離子火焰檢測器,紫外火焰檢測器資訊歡迎關注西安軒信電氣科技有限公司。
