嘉華熱工高爐煤氣放散點火工藝描述

高爐煤氣放散點火裝置工藝流程的描述
嘉華熱工高爐煤氣放散點火
一、從高爐煤氣主管道上的放散閥處引出一管道,到放散閥頂部平臺,放散口處與西安嘉華熱工設備有限公司研制開發生產的高爐煤氣燃燒器內含防焦油點火桿、長明燈、火焰監測器、動態流體阻火器、穩焰環構成,并有48米塔架支撐固定,下與工藝管道閥組儀器儀表相連,組成高爐煤氣放散塔架,及燃燒裝置。

二、整個裝置由西安嘉華熱工設備有限公司自主開發研制的放散點火控制系統軟件為核心監測控制系統中,由壓力變送器采集4-20mA,模擬量信號傳遞給PLC軟件,軟件根據工藝要求的預設值發出指令,觸發點火程序,點火過程中,放散執行機構將放散閥的開度反饋給PLC控制系統,PLC系統通過閉環控制進行PID計算,有效的控制閥門的開度,保證整個高爐煤氣管網的壓力平穩,當達到放散壓力下線值時,啟動滅火程序既打開氮氣吹掃閥,關閉放散閥,10秒鐘后關閉伴燒長明燈,整個放散結束,以備下次使用,整個放散過程中,在中控室DCS上位機的PC界面用whcc組態的系統,對點火成功及點火失敗報警、及壓力變送器所送信號進行連鎖反饋控制,整個系統渾然一體,在中控室PC機畫面一目了然,整個系統穩定安全運行。
