     煤氣在使用過程中容易產(chǎn)生管網(wǎng)壓力波動,存在不安全因素。煤氣柜作為調(diào)劑煤氣供應(yīng)、減緩管道波動的有效方法,在冶金和化工等行業(yè)得到了廣泛的應(yīng)用。煤氣柜可以有效回收放散煤氣,充分合理利用企業(yè)內(nèi)部的附產(chǎn)煤氣,調(diào)節(jié)管網(wǎng)壓力。作為煤氣這個危險性氣體的“歸宿”,煤氣柜的安全運(yùn)行對于全廠的生產(chǎn)安全具有重要意義。
      山東金能科技股份有限公司是一家綜合性化工企業(yè)。多年來,公司秉承 “資源高效、綠色低碳”的循環(huán)發(fā)展理念,以技術(shù)創(chuàng)新為驅(qū)動、以資源高效利用為導(dǎo)向,打造了區(qū)別業(yè)內(nèi)其他企業(yè)的循環(huán)經(jīng)濟(jì)產(chǎn)業(yè)鏈,構(gòu)建了資源利用、產(chǎn)品結(jié)構(gòu)、技術(shù)裝備、環(huán)保模式四大差異化的盈利模式,實(shí)現(xiàn)了煤化工與精細(xì)化工的科學(xué)整合,做到了資源利用最大化與資源利用價值最大化。
      由于金能科技現(xiàn)有的30000m2煤氣柜控制系統(tǒng)在設(shè)計時不具備硬件的冗余、容錯和復(fù)雜邏輯判斷等功能,當(dāng)現(xiàn)場儀表出現(xiàn)顯性故障時,極易造成工藝事故。為提高全廠的安全水平,金能科技決定利用冗余控制技術(shù),升級現(xiàn)有的煤氣柜監(jiān)控系統(tǒng)。
      挑戰(zhàn)
      煤氣柜監(jiān)控系統(tǒng)是智能自動化儀表技術(shù)、自動化控制系統(tǒng)、計算機(jī)技術(shù)和網(wǎng)絡(luò)技術(shù)等多種技術(shù)的結(jié)合,涉及到多方面的知識。新系統(tǒng)的設(shè)計需要重點(diǎn)解決現(xiàn)有系統(tǒng)面臨的以下三方面問題:
       故障安全:原有系統(tǒng)配置不能夠排除當(dāng)現(xiàn)場儀表出現(xiàn)故障或假液位造成的顯性故障,易造成工藝事故。
       傳感器的獨(dú)立設(shè)置:對參與聯(lián)鎖的各個傳感器(如活塞高度、氣柜內(nèi)壓力等值)配置為單臺測量,未使用不同的測量方式,不符合傳感器冗余設(shè)置三選二的原則。
       硬件的冗余、容錯:模塊前期設(shè)計時,未考慮PLC模塊的冗余、容錯設(shè)計,如發(fā)生儀表的損壞、模塊損壞、電源異常斷電等故障時,極易造成工藝事故。
      解決方案
      針對金能科技干式煤氣柜實(shí)際情況,基于羅克韋爾自動化組態(tài)技術(shù)和人機(jī)界面檢測技術(shù),金能科技構(gòu)建了現(xiàn)代化的煤氣柜監(jiān)控系統(tǒng),并與原有控制系統(tǒng)實(shí)現(xiàn)了無縫的融合與兼容。
      項目總體實(shí)施過程包括五個步驟:氣柜監(jiān)控監(jiān)測系統(tǒng)總體的方案設(shè)計;氣柜監(jiān)測系統(tǒng)邏輯關(guān)系模型的建立;冗余、容錯目的的達(dá)成,及數(shù)學(xué)模型的建立;完成氣柜監(jiān)測系統(tǒng)軟件部分的組態(tài)設(shè)計與開發(fā);最終系統(tǒng)的聯(lián)調(diào)聯(lián)試以及持續(xù)改進(jìn)。
      新系統(tǒng)采用由羅克韋爾自動化PLC冗余控制系統(tǒng)結(jié)構(gòu),基于ContrlNet協(xié)議、工業(yè)以太網(wǎng)協(xié)議等通信方式,實(shí)現(xiàn)了傳感器、電源、控制單元以及通信的冗余設(shè)置,控制精度達(dá)到毫秒級,保證系統(tǒng)安全可靠運(yùn)行??梢酝瓿蓪ΜF(xiàn)場活塞高度、氣柜內(nèi)部壓力、油槽液位、頂部泄漏量的數(shù)據(jù)的采集和進(jìn)出口閥門等閥門的過程控制。對于輸入、輸出模擬量信號通過加裝防爆安全柵(一入兩出)進(jìn)行現(xiàn)場與控制系統(tǒng)的安全有效隔離,現(xiàn)場檢測信號一分為二,一路進(jìn)原有系統(tǒng)顯示報警,另一路進(jìn)本系統(tǒng)參與聯(lián)鎖控制,雙重保證檢測信號的穩(wěn)定性和安全性。系統(tǒng)所有開關(guān)量輸入、輸出信號都通過隔離繼電器隔離,保證測點(diǎn)的干接點(diǎn)輸入和輸出。
